AUTOMATIC SACKFILLING AND SEWING MACHINE.

SPECIFICATION forming* part Of Letters Patent N O. 548,029, dated OCtOber 15, 1895. Application led October 15, 1894.. Serial No. 525,969. (No model.)

To @ZZ whom t may concern.-

Be it known that we, JOHN T. BIBB, ofTacoma, in the county of Pierce, and ARTHUR T. TIMEWELL, of Spokane, in the county of Spokane, State of Washington, have invented certain new and useful Improvements in Automatic Sack Filling and Sewing Machines, of which the following is a specification, reference being had to the accompanying drawings,

1o and to the letters and numerals of reference marked thereon.

This invention relates to means for sacking grain, ore, and other materials and for sewing the sacks after they are lled. It is designed to be an improvement on the invention disclosed in Patent N o. 476,7 78, granted to us June 14, 1892, and to which reference should be made.

In the drawings, Figure l is a perspective zo View of the machine. Fig. 2 is a plan of the same. Fig. 3 is a plan, on an enlarged scale, of the sack-holder. Fig. 4 is a vertical section on the line zc, Fig. 2, showing the devices to close the sack-holder. Fig. 5 is a plan 2 5 of the table-top, several parts of the machine being removed; and Figs. 6 to I3, inclusive, are details.

Similar letters and numerals of reference indicate similar parts in the respective figures. rhe table-top A is made of cast-iron or pressed steel, with its edge a turned down, as shown. It is provided at one end with adiamond-shaped hole a', from which aslot a2 eX- tends to near the other end of the table.

3 5 Flanges a3 are attached to or cast on the table-top to support and guide the sack-holder during its progress through the machine, and a series of rollers a4 are arranged in the tabletop at the opposite sides of the diamondy4o shaped hole a and the slot a2. The sackholder travels on these rollers through the machine, and they also serve to elevate it slightly above-the table-top to provide a space in which the sewing-needle can play, as will be described hereinafter. The table-top is supported by a series of legs B, (preferably made of T-iron,) bolted to thetable, as shown, and Ysuitably secured and braced at their lower ends by the frame b.

At each end of the machine a shaft C is journaled in suitable bearings c c, secured to the table-legs. These shafts each carry a sprocket-wheel c and two pinions c2 c2. The pinions c2 engage, respectively, racks cl d, attached to or forming parts of the ends of the frame D. The sprocket-wheels c c on the shafts C C are connected by the chain c3, and one of the shafts C is provided with a crank c4. By operating the crank c4 both ends of the frame D may be elevated or lowered, as desired, the object being to adjust the height of the frame to sacks of different lengths. Journaled in the frame D are four rollers, three of which are shown-viz., e, e', and e2. The shafts of the rollers e and e2 extend be youd the frameon one side thereof and are provided with sprocket-wheels f f driven by the chainF, which latter is driven by the sprocket-wheel g on the counter-shaft G, which receives its movement from the main drivingshaft H. A sprocket-wheel f2 is carried by a shaft journaled in suitable bearings on the frame b and serves as an idler around which the chain F runs. The rollers e and e carry the traveling bed or conveyer E and those e2 and e3 the conveyer and shaking-bed E. When the machine is in operation, the traveling bed E moves continuously; but the shaking-bed E has an intermittent travel. This is accomplished as follows: The sprocket-wheel f turns loosely on its shaft and carries on its inner face one half of a clutchft, (not shown,) the other half being keyed on the shaft and capable of being moved into engagement with the half on the sprocket-wheel by means of the rod f5, the latter being operated as hereinafter described.

Depending from each side of the frame D are brackets e' o', in which shafts I I are mounted. Each of these shafts carries two eccentrics t" o" and each is provided with a crank i2, the cranks of the two shafts beingconnected by the rod is. The end of one of the shafts I is connected to the lever J, and by rocking the lever the shafts I and their eccentrics i i will be partially rotated.

K is a frame having a convex top engaging the under side of the shaking-bed E. This frame K is within the frame D and adapted to have a vertical movement. It is provided with four legs Za 7c Zo Za, each having a caster k. The casters rest on the eccentrics t" t', and as the latter are operated by the movement of the leverJ the frame K and shakingbed E will be given a vertical reciprocating movement, which will shake the grain or other material into the corners of the sack.

The sack-holder X consists of four channeled metal bars 1, 2, 3, and 4, hinged together at their ends, as shown in Fig. 3. A crosssection of the bar is seen in Fig. 6. The holder is normally forced open by the springs 5 5 at the end joints. Near the ends are springaotuated claws (5 6, to which the upper corners of the sack are attached, these claws be ing operated in a manner similar to that described in our patent aforesaid. The sides of the sack are attached to hooks 7 7, hung on rods 8 8, adapted to have a sl-ight longitudinal movement iu the bars. The rods 8 8 are connected to levers 9 94011 the side joints ofthe holder, and the opening or closing of the latter effects the movement of the rods and the hooks 7 7, hung thereon. `Secured within the channel of the barsl, 2, 3, and 4 are a series of blocks l0 10, having inclined top surfaces. (See Fig. 7.) These blocks are so arranged that when the holder is opened the hooks 7 '7 will be caused to ride up their inclined surfaces and assume a horizontal position; but when the holder is closed the hooks 7 7 will move down the inclined surfaces and their points will hang down, `so that the sack will easily detach itself from them Whe-.n discharged at the delivery end of the machine. The bars 1 2 3 4 on their inner faces are each provided with a series of teeth 11 11 and recesses l2 l2. The teeth on one bar are adapted to the recesses of the opposite bar and serve to hold the sack when the holder is closed. The bars 1 and 2 on their upper surfaces are provided with a series of teethfwhich form, when the holder is closed, a rack 13.

L is a lever pivoted at Z on the frame-of the machine. At equal distances on each side of the pivot Z the vertical rods Z Z are connected at their lower ends to the lever L. At their upper ends these rods Z Z are attached to t-he short arms of bell-crank levers Z2 Z2, pivot-ed in brackets Z3 Z3, depending from the under side of the tabletop.

M M are rods secured at one end to therim a of the table and at their other ends to lugs m m on the under side of the `table-top. The

lugs .m m are provided with apertures through which the barsNNslide. Each of these bars is -upturned at its front end, andthe upturned portions fn 'n when in their normal positions project above the table-top and occupy the recesses n n at the side angles of the opening ct in the table-top. The rear ends ofthe bars N N have downwardly-projecting lugs n2 n2, which slide on the rods M M and are connected by links Z4 Z4 to the long arms of the bell-crank levers Z2 Z2. Spiral springs m m are titted on the rods M M between the lugs n2 and m and serve to maintain the bars N N in their normal positions. Vthcn the sacloholder is open and in place around the opening a in the table-top, the ends n n of the bars N N will engage the side joints of the sack-holder, and when the lever L is operated the bars N N will be caused to approach each otherand thereby close the sackholder. The movement of the lever L also effects the movement of the rod f5, the latter being connected atits upper end to the upper end of one of the vertical rods Z', thus partaking of its movement.

The counter-shaft G carries two pulleys g g and a spur-gear g2. Another shaft O is journaled in suitable bearings o o on the table-top. This shaft also carries two pulleys o o and a spur-gear o?, corresponding to the similar elements on the counter-shaft G. The shaft O is positively driven by the sprocketchain o1 from the shaft G. Belts c3 03 are driven by the pulleys g and-o andare for the purpose of returning the sack-holder from the delivery end of the machine, afterthe sack is released from it, to the opening a. The spur-gearsg2 o2 are adapted to engage the rack 13 on the top ofthe sack-holder and aid in drawing the holder and sack through the machine.

Pis a tube secured by suitable means to the under side of the table-top, and within this tube is a rod 79, with a surrounding spiral spring p. The rod p is free to have longitudinal movement in the tube P and when pushed outwardly will compress the spring 19. The forward end of the rod p is bent at an angle and provided with a head p2, which 4projects up through the slot a2 in the tabletopin the path of the sack-holder X. As the holder and sack travel through the machine, the rod p will be pushed forward against the force of the spring 1J until the holder opens `and becomes disengaged from the sack, when the force of the spring p will retract the rod pand force the sack-holder up the inclined bars Q Q onto the belts 03 03, which latter will return it tothe operator. The flanges ai on the table-top are arranged in a diamond shape at theidelivery end of the machine to permit the sack-holder to open by the force of the springs 5 5.

The bars Q Q are pivoted at one end to the table and normally lie in the slots q q in the table, their free ends being supported by triggers q q', (see Figs. 5 and 11,) pivoted on the under side of the table. Fach trigger is operated by a rod q2, adapted to slide in bear ings secured to the table. These rods are held in their normal position by springs g3. Only one bar Q and its elevating mechanism is shown in Fig. 1l; but `it is to be understood that the other bar Q is actuated in a similar manner. The rods q2 are operated by bellcrank levers g4, connected either to the le ver L or the rods Z. The movement of the lever L therefore effects three operationsviz., closing the sack-holder, bringing the two IIC halves of the clutch (not shown) into engagement, and lifting the bars Q Q.

The sewing device is indicated as a whole by S, the needle being indicated by s. The needle reciprocates immediately above the table-top and enters the sack close below the sackholder, the rollers a4 elevating the latter a suflicient height above the table-top to permit this action. The flanges 0.3 are cut away for the passage of the needle.

As we do not limit ourselves to any special form of sewing device, itneed not be further described herein, and reference is made to our said former patent as illustrating one form of mechanism to perform the sewing.

The general operation is as follows: The sack-holder X. is placed in its open position over the opening a and the sack attached to the hooks 6 and 7. The grain or othermaterial is then fed into the sack, and during the lilling the operator rocks the lever J, which imparts to the shakingbed E a vertical reciprocating movement and shakes the material down into the corners of the sack and aids in packing it closely in the sack. When the sack is lilled, the operator depresses the lever L, which movement closes the sackholder, brings the two halves of the clutch f4 into engagement, and thereby causes the shaking-bed E to travel, and elevates the free lends of thebars Q Q. The spur-gear g2 will now engage the rack 13 on the sackholder, and the sack will travel through the machine, being sewed during its passage. The spur-gear o2 will also engage the rack 13 and continue the forward movement of the sackholder, which will push the head p2 and rod p forward with it. When the sack-holder reaches the triangular shaped part of the flanges d3, the springs 5 will force it open and the sack will become detached from it. At the same time the spurgear o2 will be disengaged from the rack 13, andthe rodp will be retracted by the spring p and carry the sack-holder with it, causing the latter to ride up the rods Q Q onto the belts o3 05, which latter will return it to the operator ready for the attachment of another sack.

Having described our invention, we claimn l. In a machine for filling and sewing sacks, the combination with a table having an opening and a sack holder adapted when open to lit around said opening, of spring retracted bars engaging the sides of the sackholder, a lever, rods, bell-cranks and links connecting the lever and said bars whereby thesack holder is closed, substantially as specified.
