19 Claims.

This invention relates to fastening devices employing flexible stringers adapted to be coupled and uncoupled, and particularlyto a slide mem= ber'engagingsaid devices for coupling and uncoupling the same and still further to a lock device for retaining the slide member in different positions of adjustment, and the object of the invention is to provide a slide member of the class specified with an operating finger-piece m movable relatively to the slide member and by means of which said member may be moved into its several positions; a further object being to provide means on said finger-piece adapted to be automatically moved, by gravity, into posi- 35 tion to engage the coupled links or other elements of the stringers of the fastening device and to be positioned adjacent one end of the slide member, whereby lateral pull or stress on the separate stringers or garments parts to which 24 they are attached will operate to automatically move the slide member into position to engage said means to fixedly secure and lock the slider against further movement; a further object of the invention being. to provide means on the slide member, engaging said finger-piece in the locking movement above referred to, for retaining said finger-piece and the means thereon in locked position and to prevent accidental displacement of said finger-piece; and with these and other g objects in View the invention consists of a device of the class and for the purpose specified which is simple in construction and operation, efidcient in use, and which s constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reierence characters in each of the views, g and in whicht-- v Fig. l is a plan view of several parts of my device mounted upon a portion or" a fastening device;

Fig. 2 is a side and sectional view of the de- 5 vice as seen in Fig. i;

.Fig. 3 is a view similar to Fig. 2 but showing the parts in a different position;

- 4 is a sectional view through a fingerpiece and lock device which i employ, the secgo tion being on the line l of Fig. 5;

Fig. 5 is a plan view of the device as seen in Fig. 4; and,

6 is a section on the line 6-6 of Fig. 3 with the slide member detached.

in Fig. 1 or the drawing, 1' have illustrated separate portions 10 and ll of a garment or two independent garment parts, to each of which are secured stringers 10a11a having interlocking links or other element 10b11b, such for example as the stringers and links of the fastening to device disclosed in my prior Patent No. 1,557,304, dated Oct. 13, 1925, and at 12, I have shown a coupling or slide member mounted upon and movable longitudinally of the stringers 10a-11a, and by means of which the links 101) and 11b of on said stringers are adapted to be coupled and 1121 coupled. I

The slide member 12, in the construction shown, comprises a die-cast body of unitary construction having diverging channels 12d12b interto secting at the contracted end of said body and separated at the enlarged end thereof by a partion wall 120 which tapers toward the contracted end of the body and terminates in ribs 12d in the upper and lower faces of said body, said it ribs extending to the contracted end of said body and adapted to enter the recesses between the links 10b11b, when coupled together and to facilitate the coupling and uncoupling of said links in the operation of the slide member.

The enlarged end of the member 12 is provided with laterally extending wings 13 which extend well upon the attached portions oi the stringers and prevents any possible displacement of the fastening device from the separate stringers in as the operation thereof, and especially when the stringers assume angular positions with reference to the longitudinal plane of the slide member, the inner adjacent facesof the wings 13 are fiattened as seen at 130; to insure this operation. Oh so one face of the slidemember 12 is a projecting rib 1d, T-shaped in form in cross section, to pro? vide grooves 15 at the opposite sides of said rib, to receive inwardly projecting fingers 16 at one end or" a finger-piece 17 employed for operating as the slide member 12. The rib 14 extends around the enlarged end of the slide member 12 to the opposite face of said slide member as seen at 18,

and the grooves 15 at'this end of the slide member are opened in the initial manufacture of the deme vice, to permit of the attachment of the fingerpiece 17 and then closed by forcing the top wall of the rib 14 inwardly as seen at 19.

In the construction shown, the closed end of the channeled or grooved rib 14 projects slightly beyond the contracted or lower end of the slide member 22 to-iorm a cam face 20 spaced slightly from the links 10b, 11b when the device is in use as seen in Fig. 2 of the drawing, and said end of the rib is also provided with a projecting lock bar or finger 21. The finger piece 17 has an enlarged apertured end portion 22 which may be curved slightly as seen in Fig. 4 of the drawing, and this end portion is adapted to be grasped by two of the fingers of the hand in the manipulation of the slide member. The contracted end of the finger-piece provided with the inwardly directed fingers or lugs 16 is apertured as seen at 23, the aperture being formed by stamping an L-shaped lock, pawl or member 24 from the material of the finger-piece 17, so that one leg of the L-shaped lock or pawl 24 is in spaced and parallel relation to the finger piece, and the end of said lock member 24 is pointed and curved outwardly, as seen at 25, to form a prong adapted to engage and pass between adjacent links 10b11b of the stringers when coupled together, and the rounded outer face 26 of the lock member 24 is adapted to engage the rounded cam face 20 on the slide member 12 to firmly force the prong end 25 of the member 24 into engagement with the links, and also to function as a wedge disposed between the coupled stringers and the slide member 12 to lock said member against displacement, and particularly downward movement or the separation of the stringers.

It will also be noted that in the above described operation, the lock bar 21 on the rib 14, which is positioned within the aperture 23, engages the rounded edge 2'7 of the member 24 where it joins the finger-piece 1'7 and passes into the fiat surface of the finger-piece, as seen at 28 in Fig. 3 of the drawing, and operates to retain the fingerpiece and the lock member 24 in the position seen in Fig. 3 against accidental displacement. and it will also be apparent that this structure will retain the finger-piece against flapping or.clattering movement common in other devices of this class, especially when used on galoshes and like apparel.

The above described operation will be more clearly understood from the following description. When the slide member 12 has been moved into a predetermined position to couple the slide members together, entirely and partially, and said finger-piece is released the same, due to its mounting and suspension, drops by gravity into the position shown in Figs. 1 and 2 of the drawing, in which position the lock member 24 is locked beneath and in slightly spaced relation with reference to the cam face 20, and the lock bar 21 is within the aperture 23 of the fingerpiece 17, and with the parts in this position, if lateral stress or strain is applied to the parts 10 and 11 or the stringers 10a-1 la thereof, a slight downward movement will be imparted to the slide member 12, and in this operation the cam face 20 will ride upon the rounded face 26 of the lock member 24 to firmly wedge and secure the lock member in position within and between the slide member and the stringers and also definitely stop further downward movement of the slide member 12. In thisjoperation the lock bar or finger 21 slides over the surface 27 and onto the fiat face of the finger-piece 17 and operates to retain said finger-piece and lock member 24 against displacement. Of course, it will be understood that a downward pull on the finger-piece 1'! alone will disengage the parts to This application constitutes divisional subject matter of an applicationSerial Number 136,905. which was copending with this application and has issued in Patent Number 1,702,640, dated February 19, 1929.

It will be understood that my improved locking means by virtue of its automatic operation rendersthe device fool-proof and positive in function, and while I have illustrated one method of carrying my invention into effect and have illustrated its use on a fastening device employing interlocking links of specific construction, my invention is not limited in this respect, and various other changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims, without depar ing from the spirit of my invention or sacrificing its advantages.
