MACHINE FOR TACKING- SHOES.

Specification of Letters Patent.

Patented Jan. 30, 1912.

Application led January 28, 1904, Serial No. 190,932. Renewed ,Tune 1, 1910. Serial No. 564,454.

To all 'whom t may concern Be it known that I, HARRIE A. BALLARD, of Ashland, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Tacking Shoes, of which the following is a specification.

This invention has for its object to provide a pulling-over machine for boots and shoes, with means by which the pulled-over portion of the upper may be fastened to the innersole, and it has further for its object to provide a machine of the character described by means of which the manipulation of the shoe may cause the actuation of the fastener-driving mechanism so that while said mechanism is cont-rolled manually, yet it is set in motion by the manipulation of the shoe rather than by the manipulation of some other portion of the machine, as, for instance, a lever or treadle.

According to the illust-rated embodiment of the invention which is hereinafter described in det-ail, t-he machine may be provided with a gripper which may be closed manually to grip the edge of the upper. This gripper may for convenience be formed, in part, of the fastener-delivering nozzle, serrated on one face for the purpose, and a jaw pivoted to the nozzle to co-act with the serrated face thereof and adapted to be actuated by a foot-treadle. rIhe movable jaw is so arranged and located that it constitutes an abutment for the shoe, aboutwhich the shoe may be swung by the operator to draw the upper bodily about the last, to position Vit properly with respectthereto, so that its median line will coincide with the median line of the last.

- The invention may be conveniently embodied in a machine having mechanism for automatically feeding and driving tacks, but it will be understood that lany other form of fastener and fastener feeding and driving means may be utilized in lieu thereof.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, of which* Figure 1 represents in side elevation a Jracking-machine embodying the several features of this invention, and a portion of a shoe in process of lasting. Fig. 2 represents an elevation of the opposite side of Fig. 10 represents a section on the line 18-18 of Fig. 1. On the drawings,-10 represents the head or frame of the machine, which is mounted on a suitable standard, the-upper portion of which is shown at 11, in Fig. 3.

The tack-driver is indicated at 0 as attached to the llower end of a driver-bar 1. The said driver receives its motion from a shaft 12, journaled in bearings 13 13 in the head 10. The shaft 12 is rotated by a continuously-driven clutch-pulley of suitable construction, shown at 14 as mounted on said shaft. On the end of the shaft 12, adjacent the driver-bar -is aliXed a crank-disk 15 provided with a crank-pin 16. A roller 17 on the crank-pin 16 travels in a slot 18 in the driver-block 19, to which the driverbar is attached. By virtue ofthis construction and arrangement, the rotation of the shaft 12 effects the vertical reciprocation of the driver-bar 1. v As hereinafter described, provision is made whereby the-range of reciprocation of the driver-bar 1may be varied. y

The nipple-bar 20, to the lower end of which is attached-the tack-delivering nipple 21 and the gripping-lever 22, is adapted to slide in guides 23 23 in the head 10. A

backwardly-projecting extension 24 ofsaid nipple-bar engages the mechanism which causes the pulley 14 to clutch and drive the shaft 12 and automatically release and stop said shaft at the end of one complete revolution. Said mechanism comprises a plunger 25, which is mounted in a boss on the head 10. The upper end of said plunger is provided with a beveled face 250, which engages a projection 26 on the shaft 12. Said projection extends through the shaft to the clutch contained in the pulley 14. The clutch may be of any suitable construction which need not be specifically described.

The plunger 25 is normally held upward by a spring 27, and its lower end is connected to a tripping-lever 28. Said lever extends forwardly to the nipple-bar 20 and is fulcrumed at 29 to the head 10. A latch 30 pivoted at 300 to the forward end of the levell 2S rests on the extension 24 of the nipplebar 20, and is held against said extension by a spring 31. A linger 32 on the latch 30 engages an adjustable stop 33, in such manner that .when said latch is raised by the extension 2l, it raises the forward end of the lever 28 and is caused to oscillate on its pivot 800 until it has ridden off the end of said extension. In consequence of the freeing of the latch 30 from the extension 24, said latch is not affected by any further upward movement of said eXtension and the lever 2S is free to be returned to its former position by the spring 27. Not until the extension 2st has dropped to its former position does the latch 30 spring into place on said extension.

50 50 indicate the two inclined tackraces which receive the tacks from tack-reservoirs 51 51, one containing long and the other short tacks. Said races converge toward each other near the driver 0, but their slots 52 do not quite meet. At the lower end of the races 50 isgthe tack-feeder 53 mounted in a boss 54e on the head 10, and adapted to slide back and forth across the path of the tacks. Said feeder or tack-pick and the raceway may be moved one with relation to the other by any convenient means to cause the feeding` of the tacks successively to the nipple. This mechanism may conveniently include a bell-cranklever 70 fulcrumed at 71 to an ear projecting from the head and having its downwardly extending arm connected by pin 7 2 to the feeder The other arm of the lever may be connected by a link 73 to an adjustable stud 74 depending from the extension 24: of the nipple-bar 20. By reason of this construction, the vertical reciprocation of the nipple-bar causes the actuation of the tack-pick or feeder.

As previously stated, a gripping-lever 22 is mounted at the lowerend of the nipplebar 20, and is fulcrumed on a stud 61 passing through an ear on said nipple-bar. A link 62 connects the upper end of the lever 2-2 to one arm of a bellwcrank-lever 63 fulcrumed on a stud Gt on the head 10. The other arm of the lever 63 is connected by a thrust-rod 65 to a treadle (not shown) at the base of the standard 11.

A shoe to be lasted is presented to the tack-delivering nipple 21, so that the edge of the upper a projects between said nipple and the lower end of the gripping lever 22, as shown in Fig. 8. The inner faces of said nipple and gripping lever are provided with teeth, as indicated at m and y. A depression of the treadle already referred to causes the teeth y to close on the edge of the upper a which is held between the two rows of teeth m and y. The shoe is then given a forward and upward rocking motion, which causes the innersole Z) to bear against the rounded shoulder 220 of the lever 22, (see F ig. 9.) This affords a good purchase on the upper a and pulls it well over the edge of the innersole Z9. By continuing the tension on the upper and at the same time rocking it back to the position shown in Fig. 1, the shoe is ready to receive a tack.

It will be remembered that the nipple-bar 2O may have a slight upward movement in its guides 23 23. By pressing the shoe upwardly, still retaining the necessary tension on the upper, the nipple-bar 2O and its extension 24 will be raised so that the link 73 and lever will actuate the tack-feeder 53, thereby transferring a tack from one of the races 50 to the bore 60 of the nipple-bar 20, and at the same time the extension 24 will press upwardly the latch 30 which causes the lever 28 to withdraw the plunger' 25 from the projection 2G which automatically clutches the pulley 14. to the shaft 12. Thus the driver is caused to descend on the tack already placed in the bore 60 of the nipplebar 2O and drive said tack into the shoe. The latch 30 is so adjusted by the stop 33 that when the nipple-bar has reached its upper eXtreme, said latch, by reason .of the stoppage of its arm 32 by said stop, rides off the end of the extension 24e, and this allows the spring 27 to return the plunger 25 to its former position in the path of rotation of the projection 26. As the projection rotates, it engages the beveled face 250 of the plunger 25 and simultaneously unclutches the pulley 14 and arrests the rotation of the shaft 12 at the completion of one revolution. The shoe and nipple-bar 2O are then lowered, allowing the latch 30 to spring into place on the extension 24, the lever 22 is released, the shoe moved to another position, and the same operation repeated.

The race-ways are preferably connected at their lower ends and they, together with the tack reservoirs, are pivoted upon a vertical axis so that the lower end of the race-ways may be moved laterally to bring the end of either race-way into operative position with respect to the tack-feeder. The finger-lever 78 engages a pin 79 on one of the races so that, as the lever 78 is rocked up or down, it shifts the race-ways upon a vertical axis in one direction or the other. A spring 80 serves to hold the lever 78 in either of its two positions.

Provision is made for driving the tacks to a greater or lesser depth in the shoe by a shifting mechanism in the block 19 on the driver-bar 1. Said driver-bar is connected to the block 19 by a sleeve 91 contained in the block and in which the driverbar is held by collars 92 92 pinned to the drivenbar. A stud 93 which is atlixed to the sleeve 91 projects through a slot 94 in the block 19 and into a cam-slot 95 of a sliding-plate 96. Said plate is held in the block 19 by gibs 97 97. By sliding the plate 96 to one end or the other in the block 19, its cam-slot 95 coacting with the stud 93, raises or lowers the sleeve 91 in relation to the block 19. Hence the range of throw of the driver-bar 1 is raised or lowered. In view of the fact that no jack is employed, a spring 98 on the driver-bar is interposed between the sleeve 91 and lower collar 92 to absorb the shock which the operator would otherwise receive from the blow delivered by the driver-bar, but at the same time is of sufficient strength to drive the tack.

From the foregoing description, it will be apparent that the tack-feeding mechanism and the tack-driving mechanism are independently actuated, and that both are controlled by the tack-nozzle or nipple, or by the pincer or gripper.

For convenience of phraseology I have referred to the fastener driving and feeding mechanism as the tacking mechanism or tack-feeding mechanism, but I desire to have it understood that those terms are used in no limiting sense and that as previously stated herein, mechanism for feeding and driving nails, pegs, or other fastenings may be utilized in lieu thereof, without departing from the spirit and scope of the invention.

I do not herein claim the tack feeding and driving mechanism, per se, illustrated, described and claimed in my co-pending application Serial No. 276,398, filed August 30,1905, nor do I herein claim the lasting mechanism, per se, herein described, but which is described, illustrated and claimed in my copending application Serial No. 564,455 filed June 1, 1910.
