PUNCHING AND EYELETING MACHINE.

SPECIFICATION forming part of Letters Patent No. 413,752, dated October 29, 1889. Application filed January 22, 1889. Serial No. 297,179. (No model.) Patented in England June 14, 1887, No. 8,518.

T at whom it may concern.-

Be it known that we, ARTHUR GARRETT, watch-maker, ofHigh Street, Towcester, and GEORGE WEBSTER, shoe-maker, of Astcote,

bothin the county of Northampton, England,

have invented certain new and useful Improvements in Punching and Eyeleting Machines, of which the following is a specification, and for which we have received a patent IO in England dated June 14, 1887, No. 8,518.

This invention has for its object to improve the construction and efficiency of eyeletingmachines to be used chiefly inthe-manufacture of boots and shoes.

I 5 Hitherto attempts have been made to effect eyeleting in different ways. For instance, the eyelet has been caused to punch its own hole, a very unsatisfactory arrangement. Separate punching and eyeleting machines also have been placed side by side and operated by separate treadles. With this arrangement, however, any mistake of the operator in putting his foot on the wrong treadle is likely to bring down the punch when the eyelet only is required, or vice versa, and possibly punch a hole through the Vamp, or

spoil the boot by a misplaced eyelet.

According to the present invention the punch and the eyeleting ,device,'and-also the hooking arrangement, when' hooks are required in lieu of eyelets, are operated by a single lever worked by a treadle, which lever also actuates the feed of the eyelets or hooks one by one when required. 3 5 The machine consists,essentially, of a punching-cylinder, an eyelet or hook delivery or feed, and a crumping-rod for fixing the eyelet or hook in the hole punched. The mechanisms for feeding and delivering the eyelets and the hooks are substantially alike, and each of them may properly be termed an eyelet feeding and delivery mechanism, because the hooks are in effect eyelets having attachments of peculiar form and are the 5 equivalent of eyelets. Where eyelet feeding and delivery mechanism is herein referred to in a general way it is to be understood that such terms are intended to include either of the forms of mechanism shown.

In the accompanying drawings, Figure 1 is a front elevation of a machine embodying our invention, and including both the eye- Fig. 5 is a horizontal section on the line 3 4 of Fig. 4, showing the anvil or punching or riveting blocks. Figs. 6, 7, and 8 are details relating to the eyelet-feed. Figs. 9 and 10 are sectional and face views of the hookhopper and feed-box detached and in a vertical position. Figs. 11, 12, 13, and 14: show on an enlarged scale the lower part of the hook-deo 5 livery contrivance in two positions. Fig. 15' shows, also enlarged, the hook-delivery slide in cross-section, and the arrangement for insuring the delivery of the hooks one at a timer Figs. 16, 17, and 18 show in side elevation and detail a modification in connection with the punching and riveting blocks.

A is a hand ortreadle lever pivoted to the framing of the machine and provided with a spring a, for holding it normally in the raised position of Fig. 2. On the under side of this lever A is a projection a, which overlies the end of aforked slide B, jointed to the pivoted link 6. Beneath this slide 13 is the head of the punching-cylinder C, which slides vertically in the machine-framing.

At the lower end of the cylinder 0 is the punch 0, carried by the L-shaped piece of metal 0', whichis pivoted in a slot in the cylinder. The punch c is held in a vertical position by the spring 0 (shown best in Fig. 2) until pushed aside in the manner to be hereinafter described. h

Vithin the cylinder 0 is a rod D, called herein the crumpingrod. The upper end of this crumpingrod stands some distance above the upper end of the cylinder 0, andis held in that position by the coiled spring (I, lying between the collar (1 on the rod D and a projection within the cylinder. The lower 9 5 end of the rod D is provided with a spring point or needle, for the purpose hereinafter mentioned. y M

The lower part of the frame-casting contains the punching and eyeleting blocks 100 which form the anvil or resistance whereol the punching of the hole and-the riveting a1 effected. This anvil consists of a movable block E, having on its face an elastic plate, of

brass or other suitable material, to take the blow of the punch, and also a nipple for turning up and riveting the back of the eyelet. Each of these is brought successively into position immediately beneath the punching-cylinder, which also contains the crumping-rod, by the pivoted lever F, suitably provided with a set-screw to limit its rocking movement. The slidingmovement of the cylinder 0 is controlled by a lever G, pivoted to the framing, and to a link g, pivoted to a collar on the cylinder. The head of the lever. G is provided with a bowl for taking a bearing against a cam a fast on the lever A. A tension-spring g connects the lever G and the collar to which the link g is pivoted and tends to draw the cylinder 0 in an upward direction.

Z) is a stop for preventing the slide B rising too high, and b is a tension-spring for keeping the slide forward when the machine is out of action. The depression of the lever A causes the projection a to bear upon and depress the slide B, which in turn depresses the cylinder C, carrying the punch. The punch is thus driven through the work laid upon the anvil. At this point the delivery of the eyelet or hook, as the case may be, takes place.

\Ve will first describe the eyelet-delivery. The eyelets, which are of ordinary form, are contained in a feed-box H, mounted upon the side of the machine. (See Fig. 1.) This feedboX consists of a vertically-rotating drum h, a stationaryhopper, and plate, which together close its front. The drum h is perforated with radial holes. Into these holes the necks of the eyelets fall, and as the drum rotates are carried round therewith onto a supporting-plate h (see Figs. 7 and 8) within the drum, which leads to the delivery-slide I. The rotation of the drum H is in the direction of .the arrow, Fig. 3, and is effected by means of the ratchet-wheel arrangement shown in Fig. 6.

h is the ratchet-wheel, mounted concentrically with the drum, on the back plate thereof. Pivoted on the drum-spindle is an arm h carrying a pawl h*, engaging with the teeth of the ratchet-wheel. To the arm h* is pivoted a link h *,to which again is pivoted the link h flwhich itself is pivoted to the framing. ()n the lever A is a bowl a which descends upon the link h and causes that and the link h to spread and move the arm h* and pawl h round over the teeth of the ratchet-wheel. Vhen the lever A is raised, the elasticity of the coiled spring 71 causes the links 723* and to approach, whereby the arm h* is raised and an intermittent rotary movement communicated to the drum. A spring retainingpawl h** is loosely pivoted to the framing to check backward movement of the. drum, a slight reversal being, however, permitted by he play of the pawl upon its pivot, to insure a clearance of the eyelets should there be a tendency to block in the feed-box. The delivery-slide I is pivoted to the front plate of the eyelet-drum, near the exit-plate, and is suitably curved to bring its lower end near the work to be eyeleted. consists of a back plate and flanges for overlying the eyelet-heads as they slide down, neck outward. The eyeleting-slide is brought into position by the vertical rod J, which is capable of partial rotation on its axis, and which at its lower end is connected to the slide I by means of a crank-arm provided with a slot in which a loop (connected with the slide) works. There is also an outside loop fixed to the casting to prevent too great an outward movement of the feeder-tube. The rotation of the rod J is eifected by a bowl j on the side thereof, near the upper end, coming into contactwith a spring finger or latch 66* on the lever A. The depression of the lever A causes, through the projection a and slide B, the depression of the punching-cylinder O. The blow having been struck by the punch and a hole made in the work, the projection a slips from ofi the slide B and allows the under side of the still descending lever A to come into contact with the head of the crumping-rod D. At the same moment the cam (1 which, from its formation, has allowed the cylinder C to descend, begins to raise the latter by means of the lever G, and in this it has the assistance of the spring g. The dcscent of the crumping-rod D, forced down by the lever A, causes its end to protrude from the bottom of the retiring cylinder C, pushing aside the pivoted punch c. The finger of now causes the rotation of the rod J, and thereby advances the end of the eyelet-slide beneath the descending crumping-rod. The pin in the end of the crumping-rod enters the first eyelet in the slide and withdraws it therefrom past the spring retaining-plate Wherewith the slide is furnished. The continued descent of the crumping-rod carries the eyelet into the hole prepared for it, while the slide is permitted to retire, the finger a* having passed the bowl j on the rod J. After the punching, and before the delivery of an eyelet into the hole punched, the anvil receives, through the bowl of and pivoted lever F, a movement which brings the nipple into position beneath the crumping-rod, in lieu of the plate which received the blow of the punch. The lever A is now thrust completely down, and the riveting of the eyelet within the punched hole is completed.

When it is desired to insert hooks in the work instead of eyeletsas, for instance, in the upper port-ion of lace-boots for facilitating lacing-the eyelet-delivery is disconnected from the rod J and the contrivance shown on the left side of the machine, Fig. 1, and in detail in Figs. 9, 10, 11, 12, 13, 14-, and 15 is employed. The hook-feed box K is somewhat diiferent from the eyelet-feed box, and is mounted obliquely to the machine upon a The eyelet-slide IIO circular, receives rotary motion in the manwhich drives the ratchet-wheel.

ner best shown in Fig. i. A ratchet-wheel k is fixed on the back plate of the box, with which wheel engages the pawl The pawl 70 is carried by the radial arm 10 and the link k which latter is pivoted to the forked lever 70, to which back and forward movement is given by the bowl a upon the lever A and by the spring 76 The depressionof the lever A causes the backward movement of the longer arm of the lever 70', and through the arm 70 and link k draws the pawl 70 over the teeth of the ratchet-wheel. The release of the' lever 70 allows the spring to advance it, and with it all parts connected thereto, including the pawl The circular feed-box is contained within a box or hopper K open at back to permit the action of the rotating mechanism, and being of such a diameter as to allow the heads of the hooks to lie between it and the feed-box. The latter is provided internally with radial projections at its circumference, (see Fig. 10,) by which the hooks as they catch upon the edge of the feed-box are carried upward. As the-hooks reach the highest point they are received onto the edge of a plate Z, down which they slide by their ownweight into the hook-delivery slide or carrier L, a guard Z being provided for preventing the hooks from falling off the plate Z. The lower portion ofthis carrier L is fully illustrated at Figs. 11, 12, 13, 14, and 15 of the drawings. The carrier L is pivoted to brackets on the framing, and is connected to the rod J through the link j The carrier contains a channel for the hooks and a plate or rib in linewi-th plate Z, above mentioned, and is provided with an attachment L sliding in guides upon the carrier.

The attachment L* terminates in a bridge M.

The carrier is also provided with a contrivance N, for retaining the hooks and allowing them to pass one by OnwThe sliding portion L* is drawn in an upward direction by the spring 0, secured to the bracket 0, carried by the casting.

The bridge M, above mentioned, consists of back and front plates, with room for the hookhead to lie between them, and is pivoted to the sliding portion L Its normal position is such that the front plate immediately un derlies the rib within the hook-carrier. To the upper part of the sliding portion L* is pivoted the rod P, (see Fig. 13,) to the end of which is pivoted one end of the link 19. The

other end of this link 19 is pivoted to the crank-arm'm fast upon the shaft m, within the bridgeM. The shaft m extends lengthhook by a stop N* on the framing when the" carrier is advanced by the rotation of the rod J after the punching operation. The retaining device N (see Fig. 15) consists of a pair of pins 01, placed at different levels and projeeting into the channel of the carrier, near one side ofthe rib above mentioned. The pins n are carried by a U-piece n, jointed to the bell-crank lever n pivoted to the plate a Fixed to the carrier,'upon the same pivot-pin, is the plate n which lies outside the rod P and serves to take the pressure of the stop N? and transmit it to the said rod. The bell-crank lever 02 is forked (see Fig. 15) to embrace the rod P, so that the movement of the-latter rocks the former, and thereby gives a reciprocating movement to the pins 72. The hooks as they slide down within their carrier are intercepted by the upper of the two pins 01.; but on the rocking of the lever 97. the first hook is dropped by the upper pin onto the second, and from thence to the bridge M. We will now suppose the hole for the reception of the hook to have been punched. The descending lever causes the rotation of the rod J in the same manner as described with reference to the eyelet mechanism; but in the present case the hook-carrier L is connected by the link 1' to the rod J, and is therefore by its. rotation advanced to the descending crumping-rod. This advance causes the plate a to strike the stop N*, by which it is compressed against and swings the rod P into the position shown at Fig. 14. It will be noticed from this View that the bridge M has now assumed a horizontal instead of a vertical position beneath the hook-carrier, and that the hook is held neck downward upon the lower plate of the said bridge, and is retained within the notch therein by the pin m In this position the crumping-rod D descends upon the bridge and the central spring-point within it (the length of which is regulated by a suitable set-screw) strikes and holds the bridge in a central position, while the crumping-rod presses down the same and drives and rivets the hook into position in the work. After the riveting the lever A is allowed to rise and the crumping-rod to retire,as before, and the spring 0 returns the sliding portion L* toits normal position, while a flat spring 0 causes the pendent rod P, now released from 'the pressure of the plate n andstop N, to return the bridge into a vertical position ready for the next hook.

If it be desired to make use of the eyeleting or hooking mechanism without repeating the punching blow, the leverA is not permitted to rise sufficiently to bring the projection a above the punching-slide, and thus eyeletafter eyelet or hook after hook can be inserted in any kind of prepared work while the punch relnains'inoperative. v

Mention must now be made of the guide q q, provided with points, either of which can at pleasure be raised above the level -of the-anvil for securing the work in position by passing one of the pins through the lastmade hole. The guides are in the form of bellcrank levers, with the upper or horizontal arms bent inward at their forward ends (see Figs. 1 and 3) and lying in recesses cut for them in the framing on either side of the block or anvil. These arms are pierced to receive the guide-pins, (see Fig. 5,) which may be set at any desired distance from the center to suit the work in. hand. The tails of these bell-crank levers q q lie in contact with a bolt Q, sliding transversely in the framing. This bolt is provided with cam-faces, so that if slid from right to left, or vice versa, one or other of the guide-pins is raised or lowered, as required, according to the direction of Working.

It now remains to describe a modification in connection with the anvil which is shown in Figs. 16, 17, and 18 of the drawings. In this modification instead of the punchingplate and riveting-nipple being provided with a sliding movement, theirposition is changed in a rotary direction, which gives an economy in space in some cases advantageous. R is the cylindrical punching-block fast on the end of 'a horizontal shaft '7. S is a crank-arm, and s is a link for communicating motion in a rotary direction from the pivoted lever s. The punching-slide is provided with an elastically-pivoted joint to prevent too heavy a thud of the punch 011 the brass block, and so avoid the breaking of the punch-bits.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, we declare that what we claim is 1. A combined punching and eyeleting machine consisting, essentially, of a reciprocating punching-cylinder carrying a laterallymovable punch, a cramping-rod reciprocating in said cylinder in line with said punch, and a shifting anvil for receiving the punch and crumping-rod, substantially as described.
