Filed Aug. 22, 1969, Ser. No. 852,413 Int. Cl. D05b 35/00, 23/00 US. Cl. 112149 11 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION This invention relates to improvements in fur sewing machines and more particularly, it concerns an improved guide means for directing strips of fur to the feed mechanism of a fur sewing machine which operates to form a longitudinal seam joining the two strips of fur together.

In the manufacture of fur such as mink for garments, it is common practice to employ the letting out process to modify the shape of a skin before it is sewn together with other skins to form the ultimate garment. The letting out process calls for slicing the skin into diagonal strips Me to A inch in width and sewing the strips together after they have been oifset in the direction of slicing to make a longer and narrower skin to run the full length of the garment without seams showing on the fur side. It will be appreciated that this technique of modifying the shape of the skin is extremely tedious and requires highly skilled personnel, even when using currently available, precision sewing machines, because of the tolerances required in making a strong seam without wasting an inordinate amount of the fur strip in the seam itself. In US. Pat. No. 2,588,281, issued Mar. 4, 1952 to the present inventor, there is disclosed a guide mechanism for such fur sewing machines by which much of the difliculty theretofore encountered in feeding fur strips to a sewing machine was appreciably alleviated. Essentially, the guide mechanism shown in the aforementioned patent is in the form of an inverted V-shaped guide shoe, having downwardly diverging side blades and a central separating blade, which functions so that the height to which the edge portions of the strips of fur project above the feed wheel pair in a horizontal needle machine can be controlled accurately by varying the height of the guide shoe relative to the feed wheels and needle.

While the basic guide mechanism disclosed in the above-mentioned US. patent has proven to be effective in achieving its intended objective (i.e. reducing the time and skill necessary to obtain a uniform and even seam), some difiiculty has been experienced in the fur snagging or bunching against the central separating blade of the guide or otherwise extending through to the skin side of the fur and thus interfering with the formation of a completely acceptable seam. A partial solution to this problem is provided by recently developed sewing machines which employ a jet of air positioned ahead of or upstream from the guide shoe, in terms of direction of feed, so that the fur will be blown out from between the 3,572,268 Patented Mar. 23, 1971 strips of skin to be sewn. In apparatus heretofore available however, the air stream is directed normal to the skins and does not take into account the transverse lie of the fur on the adjacent skin strips to be sewn. In this latter context, it is noted that in most skins which are sliced diagonally in accordance with the letting out process referred to above, the hair on the skin lies in a direction transversely to the length of the strip. As a result, it often occurs that the hair on one of the two strips to be sewn lies or extends away from the edge of one strip whereas on the adjacent strip to be sewn thereto, the hair lies out over the edge to be sewn. As a result of this condition, there is an imbalance of hair on opposite sides of a normal medial plane between the two strips to be sewn. This imbalance of hair is neither accounted for by the air jet developing means in machinery presently available nor is it accommodated by the guide shoe of such machinery.

Another deficiency in available guide mechanisms for fur sewing machines of the type shown in the above-mentioned US. patent, is that of maintaining the guide in a central position relative to the nip of the feed wheel pair which presents the edges of the fur strips to the needle of the machine. In this connection, it is noted that in fur sewing machines of this type, one of two cooperating feed wheels is rotated intermittently about an axis fixed with respect to the machine housing whereas the other, though spring biased against the fixed wheel is free to move outwardly from the fixed wheel to accommodate different thicknesses of skins. For example, in the case of mink, the skin thickness in a female hide usually will be about .020 inch whereas the thickness of skin in a male hide will run as high as 0.060 inch. Thus it will be appreciated that the medial plane between the feed rolls will shift outwardly from the fixed roller by a distance corresponding to /2 the variation in the double thicknesses of skins to be sewn. Although optimum guiding of the strips to the wheels requires that the guide shoe be positioned directly on the medial plane between the feed discs, machines heretofore available have fallen short of such optimum guiding because they have not made provision for the varying thicknesses of skins to be sewn.

SUMMARY OF THE PRESENT INVENTION In accordance with the present invention, an improved apparatus is provided for guiding fur strips to a sewing machine which both compensates for the transverse lie of fur on adjacent skin strips to be sewn as well as for different thicknesses of skin. Essentially, the present invention contemplates a guide shoe resembling that illustrated in the present inventors prior US. Pat. No. 2,588,281, but in which the central separating blade of the shoe is pivotal over at least the forward portion of its length to account for the imbalance of hair on opposite Sides of a transverse medial plane passing between the strips to be sewn. Pivotal action of the separating blade is augmented further by an adjustable air jet nozzle which coacts with the separating blade in such a manner that when the blade is pivoted in one direction or toward that strip in which the hair lines away from the edge to be sewn, the air jet will be directed against the hair on the other strip which projects into the space between the two. In this manner, the edges of the skin to be sewn are cleared of hair in a highly eflective manner.

Also, the guide shoe and air jet are supported from the sewing machine housing to be adjustable relative to the medial plane between the feed wheels of the sewing machine. Moreover, means are provided for rendering this adjustment automatic in accordance with travel of the movable one of the feed wheel pair as different thicknesses of skin are fed therebetween. Vertical adjustment of the guide shoe is also contemplated to insure the proper depth of seam uniformly in a manner resembling that of the guide mechanism illustrated in the aforementioned US. patent.

Among the principal objects of this invention are therefore: the provision of an improved guide apparatus for fur sewing machines; the provision of an improved guide mechanism of the type referred to, which is adjustable to compensate for the imbalance of hair between a normal medial plane between the strips of fur to be sewn; the provision of such a guide mechanism in combination with an adjustable air jet nozzle to further compensate for the imbalance of hair between the strips as aforementioned; and the provision of a guide apparatus of the type referred to, which will be maintained automatically and precisely on center between the feed wheels of a fur sewing machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A fur sewing machine incorporating the improvements of the present invention is shown in FIG. 1 to include a housing, generally designated by the reference numeral 10, and having a lower base portion 12, an intermediate riser portion 14 and cover portion 16. In accordance with conventional practice, the lower housing portion 12 includes a boss 18 for supporting the bearing and final drive components of an intermittently driven, rotatable feed wheel 20 having a fixed vertical axis established by the boss 18. A second, movable feed wheel 22 is supported freely for rotation, also on a vertical axis, by a journal 24 carried on the lower end of an arm 26 formed as an integral extension of a beam 28 cantilevered from the front end of a slide rod 30 (FIG. 2). Resilient means, depicted by the compression spring 32 in FIG. 2 of the drawings, functions to bias the slide 30 and thus the arm 26 in a direction such that the movable feed wheel 22 is yieldably biased against the fixed feed wheel 20 as shown in FIG. 1. A horizontal needle 34 is carried by reciproeating means supported by the housing base 12 above the feed wheels 20 and 22 in cooperation with a needle guide 36 fixed above the movable feed wheel 22. The needle 34 cooperates with a looper 38 to form a seam between 4 two strips of fur skin fed by the wheels 20 and 22 when the machine is driven by power transmitted to a fiy wheel pulley 40.

The sewing machine components described above, as well as all other components thereof supported directly by the lower base portion 12 are conventional and well known to those familar with the fur sewing art. Additional information concerning such sewing machines may be found by reference to the above-mentioned US. Pat. No. 2,588,281 and further by reference to US. Pat. No. 2,132,379, issued Oct. ll, 1938, to C. Bonis. The point at which the structural organization of the present invention departs from that of conventional fur sewing machines is depicted most clearly in the drawings by the riser 14 and the components carried directly thereby. In this context it is noted that in conventional fur sewing machines, the cover 16 carries a lubricant to be dispensed by suitable means to the movable machine components incased within the lower housing part 12 and is movable away from the upper portion of the housing part 12 to facilitate inspection and maintenance of such sewing machine components. In accordance with the present invention and as shown in FIGS. 1 and 2, the cover 16 is pivotally supported on the riser 14 by hinges 42 located to the rear of the housing and retained in a closed position by latch means 43 on the front thereof. The riser 14, in turn, is pivotally mounted to the top of the lower housing 12 by similar hinges 46 and retained in a closed position against the housing by resilient latch means 48. Thus, it will be appreciated that the riser 14, as well as the parts carried thereby, can be easily incorporated as a module in the existing structure of presently available fur sewing machines merely by inserting the riser between the cover 16 and the lower housing portion 12.

As shown in FIGS. 1, 3 and 5 of the drawings, a fiuid conveying tube 50 is rotatably and slidably supported by the riser 14 by bearing openings formed in the front and rear walls respectively of the riser. The rear end of the tube 50 is connected to a source of compressed air (not shown), by a flexible hose 51. The portion of the tube 50 projecting from the front of the riser is formed to provide a lateral arm 52 which carries the improved fur strip guiding mechanism of this invention, generally designated in the drawings by the reference numeral 54. Although the details of the guide mechanism 54 will be described more fully in the description to follow, it will suffice at this point to note that the guide mechanism is positioned relative to the feed wheels 20 and 22 as well as the needle 34, both in term of vertical elevation or height above the operating plane of the needle and laterally with reference to a vertical medial plane passing through the nip of the rollers 20 and 22, by movement of the tube 50 on which it is supported by the arm portion 52 thereof. Specifically, relative vertical positioning of the guide mechanism 54 and the feed wheels 20 and 22 is effected by rotation of the arm 50 whereas lateral positioning of the guide mechanism relative to the medial plane of the feed wheel nip is effected by longitudinal sliding movement of the tube 50.

The manner in which the tube 50 is positioned automatically to bring about proper position of the guide mechanism 54 may be understood by reference to FIGS. 2-5 of the drawings. As shown in FIGS. 4 and 5, a collar 56 is clamped to the exterior portion of the tube 50 extending between the front and rear walls of the riser 14 by suitable means such as clamping screws 58. The collar is formed with a radially extending car 60 for supporting a laterally extending pin 62 carrying a cam follower bearing 64 on its outboard end. Thus it will be seen that the locus of the follower bearing 64 will establish both the angular position of the tube 50 and thus of the arm 52 as well as the axial position of the tube 50 relative to the riser 14 in which it is slidably and rotatably mounted. To position the bearing follower, a pair of bifurcated cam members 66 and 68 are adjustably positioned within the riser 14 as shown in FIG. 2. The member 66 is clamped about the slide 30 to which the movable feed wheel 22 is connected by way of the arm 26 and beam extension 28, thereby insuring that the cam member 66 will be moved directly with movements experienced by the axis of the feed roller 22 to accommodate different thicknesses of skin fed between it and the fixed roller 20. The camming member 68 is carried for adjustable fore and aft positioning by a rotatable screw 70 having a position control knob 72 projecting from the front wall of the riser 14. As shown in FIG. 2, the camming member 66 carries a forwardly and downwardly directed camming surface 74 whereas the camming member 68 carries a rearwardly and downwardly facing, inclined camming surface 76, the camming surfaces 74 and 76 being formed on bifurcated interleaved fingers so that the members 66 and 68 may be engaged against lateral separation. The respective camming surfaces 74 and 76 extend at 45 to the vertical and merge to establish an inverted V-shaped cradle for the follower bearing 64. The effect of this arrangment is that if the member 66 is moved forwardly by outward movement of the feed wheel 22 to accommodate an increased thickness of skin fed between it and the fixed feed wheel 20, the point of intersection between the camming surface 74 thereon and the camming surface 76 on the member 68 will be advanced forwardly by half the distance through which the member 66 is moved. Hence, the tube 50 and guide mechanism 54- will similarly be moved so that the latter maintains a medial position between the feed rollers assuming that such medial position was established initially. Manual adjustments of the position established by the locus of the bearing follower 64 may be made by rotating the knob 72 to change the fore and aft position of the bearing member 68. The bearing follower 64 is maintained in the cradle established by the surfaces 74 and 76 by a treadle (not shown) connected to linkage 77 coupled to the rear end of the tube 50. A return spring 78 (FIG. imparts a rotational bias on the tube 50 against the treadle. Also, a mercury switch 79 (FIG. 1) is carried by the link 77 to control the delivery of air to the hose 51 in a known manner.

A more complete understanding of the guide mechanism 54 and its operation may be had by reference to FIGS. 6-12 of the drawing. As shown in FIGS. 68, the guide mechanism 54 includes a guide shoe 80 having an elongated ridge plate 81 and a pair of outwardly diverging side blades 82 extending from the sides of the ridge plate 81. A bifurcated supporting plate 84 extends upwardly from the ridge plate '81 for attachment to a strut 86 by a screw 88, the strut 86, in turn, being attached adjustably to the terminal end of the tube arm 52 by a further screw 90. The leading end of the shoe 80 is formed with a notch 92 (FIG. 8) in the ridge plate portion 81 to receive a pivotal separating blade 94 (FIG. 6) having a similar notch 96 formed therein at the base of an upstanding control lever portion 98. As shown most clearly in FIG. 6, the separating blade 94 tapers rearwardly to a point 100 at its trailing end. The shoe 80 and separating blade 94 are preferably assembled by advancing the blade 94 longitudinally under the ridge plate 80 of the shoe until the notches 92 and 96 interengage to establish a pivotal connection between the blade 94 and the shoe 80. To secure the assembly, the trailing tip 100 of the blade 94 is soldered, welded or otherwise fixed to the ridge plate 81 centrally thereof. Since the trailing tip 100 undergoes very little if any movement, this manner of connecting the separating blade 94 to the shoe 80 will permit pivotal movement of the leading end of the blade 94 relative to the shoe 80 with a slight measure of flexing in the blade 94 due to the fixed connection of the tip 100 thereof to the shoe.

An air nozzle in the form of a cylindrical sleeve 102 is rotatably mounted on the open end of the tube arm 52 and carries a plurality of inclined louver-like vanes 104 or other fluid directing means across the terminal end or mouth thereof. An aperture 106 formed in the side of the sleeve 102 is notched to cooperate with a pin 108 on the arm 52 to facilitate angular adjustment of the nozzle and thus of the vanes on the tube arm 52. A knob 110 may be provided on the nozzle 102 to facilitate such adjustment manually. Also, it is to be noted that the mouth end of the sleeve 102 is formed with a notch 112 to receive the control arm 98 on the separating blade 94, the assembled connection of these two members being illustrated most clearly in FIG. 7 of the drawings.

The notch 112 is located to lie in a diametric plane normal to the vanes 104, or parallel to the direction in which air is deflected by the vanes 104, and on the side of the sleeve 102 toward which the air is directed by the vanes. Because of this arrangement, when the nozzle 102 is rotated to change the direction of air flow as directed by the vanes 104, the upstanding control arm 98 on the separating blade 94 will be carried with the notch to pivot the blade 94 in a direction opposite to that in which air is directed by the vanes. The importance of this interrelation of the blade 94 and the nozzle 102 may be appreciated by reference to FIGS. 10-12 of the drawings. The cross-section through a pair of fur strips A and B in FIG. 10, is taken at a plane located immediately upstream of nozzle 102 as it is shown in FIG. 9. The two strips A and B each include a skin S and fur F, the skins being symmetrically disposed relative to a medial plane YY which lies midway between the feed Wheels 2 0 and 22. Because of the natural pitch or lie of the fur F on the respective skins, the fur on the strip A extends over the edge of the skin and into the medial plane YY whereas the fur on the skin B extends in the other direction or away from the medial plane YY. Inasmuch as the fur sides of the two strips A and B are brought against one another by the feed wheels 20 and 22 in the actual sewing operation, it will be appreciated that the fur on the strip A will tend to project behind the skin S and pose problems to the development of an effective seam. In accordance with the present invention however, this problem is overcome in part by the directional air nozzle 102 and in part by pivotal movement of the separating blade 94. Specifically, and as shown in FIG. 11, upon passing under the air nozzle 102 which has been adjusted to direct air more heavily against the fur of the strip A than on the strip B, the fur tending to project up through the seam on the strip A will be blown downwardly as shown. Because there will be a build-up of fur on the sewing edge of the strip A, the corresponding pivotal action of the separating blade 94 as shown in FIG. 12 will compensate for this build-up and facilitate the guiding of the strips to the feed wheels 20 and 22 of the sewing machine. Yet the adjacent or seam edges on the respective strips A and B will be presented in true overlying coextensive relation to the feed wheels 20 and 22, the height of the skin above the needle 34 being governed by the lower surface of the ridge plate 81 in the manner described in the aforementioned US. Pat. No. 2,588,281.

To prepare the machine for operation, the operator first determines the lie of the fur F on the two strips A and B to be sewn and adjusts the nozzle 102 so that the proper notch in the opening 106 therein registers with the pin 108 on the arm 52. In the example illustrated in FIGS. 1012 of the drawings, the nozzle 'would be adjusted so that the vanes 104 therein were inclined toward the left of the medial plane YY and so that the blade 94 beneath the ridge plate 81 in the shoe is inclined toward the right as shown respectively in FIGS. 11 and 12. If on the other hand, no detectable imbalance of hair at the edges of the strips to be sewn could be observed, the nozzle and thus the blade would be adjusted to a neutral position or one in which the vanes were directed in line with the medial feed plane Y-Y and so that the blade 94 assumed a truly vertical position. Correspondingly, if the imbalance of fur on the strips were the reverse of that shown in FIGS. 10-12, the nozzle and blade would be adjusted to the opposite direction of that shown.

Because of the return spring 7 8 (FIG. 5), the rest position of the arm 52 will be elevated to that shown by phantom lines for example, in FIG. 9 of the drawings. To initiate the sewing operation, the treadle (not shown) to which the linkage 77 is connected is depressed, causing air to how through the tube 50 and out through the nozzle 102, and rotating the tube 50 so that the arm moves downwardly to the position illustrated in solid lines in FIG. 9 of the drawings. This operative position of the arm 52 and thus of the guide mechanism 54 is established by engagement of the follower bearing 64 on the pin 62 connected to the tube 50 (FIGS. 2 and 4) moving into the inverted V-shaped cradle established by the inclined camming surfaces 74 and 76 on the members 66 and 70 respectively. As various thicknesses of skins are incurred, causing outward movement of the feed wheel 22 relative to the fixed axis feed wheel 20, the cam member 66 will be moved accordingly. Because of the 45 disposition of the cam surfaces 74 and 76, the locus of the cradle formed thereby and thus of the bearing follower 64 will be moved through half the distance through which the wheel 22 is moved to maintain the feeding center of the guide shoe 80 and blade 94 on the medial plane between the feed wheels 20 and 22. Some attendant vertical repositioning of the guide shoe 80 will occur with such lateral positions. Because the swing of the shoe approaches tangency with the plane of the needle 34, however, such vertical repositioning will be negligible. If on the other hand, the wheel moves through a distance exceeding that anticipated with the particular skins of the fur strips being sewn, an appropriate adjustment can be made by repositioning the cam member 68 by manual rotation of the knob 72.

Thus it will be appreciated that by this invention there is provided a highly improved guide mechanism for fur sewing machines and by which the above-mentioned objections are completely fulfilled. Although the embod ment disclosed is preferred, structural variations therefrom are contemplated. Accordingly, the foregoing description is intended to be illustrative and not limiting in connection with the true spirit and scope of the present invention.
