HEELHVIACHINE.

forming part of Letters Patent No. 329,022, dated @ctobez 27,1885. Application filed November 26, 1884. Serial No. 148,870. (No model.)

To all whom it may concern:

Be it known that I, FRnDnnIoK W. CoY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Heel-Machines; and I do hereby declare that the following is a full, clear, and exact description of the'same.

My invention is an improvement in heelmaking machines, and is especially designed as an improvement upon the machine shown in the patent of Edward H. Parks, granted by the United States Patent Oiiice on the 22d day of April, 188st, and numbered 297,487.

The main part of the invention consists of an'attachment to said machine, or to similar machines, for the purpose of inserting pegs or nailsin the heel after it has been formed. Some modifications have also been made in parts of the machine, mainly to conform to the said attachment.

In the machine shown in the aforesaid patent the lifts of which the heel is made are held together by means of paste applied to each lift after it has been cut. In working with some kinds of leather it has been found in practice that the lifts tend to curl or warp, and thereby separate, and it is to obviate this difiiculty occurring when such leather is used that the attachment above mentioned is provided. It is designed, therefore, for optional use, and the main machine may be used either with or without it.

The main feature of the invention consists in the combination of a pegging or nailing attachment with a heel making machine, in which the lifts are cut and placed together, and the nails or pegs afterwards inserted when in line with the movement of the dies carried by the table supporting the same.

The subordinate features of the invention are also hereinafter explained and specificall y claimed.

In the accompanying drawings I have shown an attachment adapted to insert pegs, and have confined the d scription to this form; but it will be well understood by those skilled in the art to which my invention appertains that peg-driving and nail driving mechanisms are old and equivalent mechanisms, and I do not limit myself to the particular kind of peg or fastening-pin, since the special peg cutting and feed- .pegging-machine is supported.

ing devices may be exchanged for known devices for feeding nails to the driving -instrument with the same effect. I have shown only so much of the said Parks machine as I deem 5 5 necessary to indicate the place and manner of attaching the aforesaid lift-fastening devices, and to include the other modifications hereinafter explained.

In these drawings, Figure 1. is an elevation of the left-hand side of the Parks machine, showing the attachment in place and in end view. Fig. 21s an elevation of the attachment as seen when looking from the rear of the ma chine. Fig. 3 shows in plan a section on line 6 00 cc of Fig. l and y y of Fig. 2. Fig. 4 is a view of the front of the attachment, the die being shown in place upon the bed. Fig. 5is a detailview of the peg-strip-feed mechanism, the cutting-knife, the driver, and awl, the V hinged plate being represented as thrown back in order to better show the feed rolls ordrums, &c. Fig. 6 is a section on line 2 a of Fig. Fig. 7 is a section on line 2: o of Fig. 6. Fig.

, 8 shows in plan the supporting-bracket for the 7 5 attachment. Fig. 9 is a section on line to w of Fig. 2. Fig. 10 is a section on line a a of same figure, and Fig. 11 is a detail view. Fig. 12 is a detail view of the mechanism for operating the conveyor-arm. represent details of the mechanism for operating the discharge-arm, Fig. 14. being a section on line y y, Fig. 13.

In these drawings, A A represent the sides or standards of the machine. Viewed from 8 the rear, (the attachment being on the rear of the machine) Ais the right-hand side piece or standard. To it is bolted a bracket, B, provided with a plate or base, b, on which the A stud, 1, 9c (dotted lines of Fig. 2,) is set in this plate and forms the pivot on which turns the frame of the pegging mechanism. A slot, 2, Fig. 8, in the other end of the bracket B, struck on a curve from the stud as a center, receives a 95 screw, 3, set in the lower face of the frame G, and limits the movement of said frame, while the screw-head prevents any upward movement of the frame by the concussion of the awl and driver-bars. The frame 0 is prefer- IOO ably a single casting having bearings 01 c for the main shaft 3 of the pegging mechanism.

Figs. 13 and 1t v Loose on this shaft is a sprocket-wheel, 4, connected to the shaft 3 by means of a springclutch, 5, splined to the shaft and pressed into contact with the toothed hub of the wheel 4 by means of springs. The sprocket-wheel runs constantly, being driven by means of a chain from another sprocket-wheel, 6, on the shaft G of the machine. The clutch'5 is thrown out of connection with the hub of the sprocketwheel by means of a bell-crank lever, f, pivoted on a stud on the bracket B. The lever has an arm, 7, provided with an incline, 8, adapted to impinge against a spur on the rim of the clutch, and thus throw said clutch out of gear with the hub of the sprocket-wheel.

The bell-crank lever is operated from an arm, 9, to which it is connected by a rod, 10. This arm is on a short shaft, 11, in bearings on the frame side A, the inner end of the shaft being provided with an arm, 12, a frictionroller on the end of which bears against a wheel, 13, on the shaft '14 of the machine. This wheel 13 is provided with a stud, 113, adapted to strike a corresponding stud on the arm 12, and through the described connection throw out the leverf, and thus allow clutch 5 to come in contact with the sprocket-wheel clutch at the proper moment and start the pegging mechanism, as hereinafter fully explained.

()n the inner end of the shaft 3 is a cam, 15, which acts upon a friction-roller, 71, on an arm, 16, fixed upon the bracket-plate b, so that when the shaft revolves and the high part 72 of the cam bears-against the friction-roller it causes the frame 0 to swing laterally on its pivoting-stud 1. A spring, 17, on the bracket bears with its free end against a stud on the frame (J, and causes the frame to return when the high part of the cam has passed the roller on the fixed arm 16. The particular shape of this cam and the precise movement of the frame are hereinafter described fully in connection with the mechanism for making the holes and driving the pegs.

In bearings in the frame 0, and above the shaft'3, is a shaft, 19, driven from a pinion, 20, on shaft 3, by an intermediate pinion, 21, in mesh with a pinion, 22, on shaft 19, the gearing being adapted to move shaft 19 twice as fast as shaft 3. The shaft 19 carries on its inner end a lifting-cam, 23, adapted to catch under a shoulder, 24, on a bar, 25, said bar sliding vertically in guides 26 and 27, and carrying on its lower end the peg-splitting knife 28. A rod, 92, forming an upper prolongation of the bar 25, is in a housing, 30, and is provided with a spring, 31, which throws.

down the bar, forcing the knife to split off a peg from the strip at each stroke. This bar also carries the driver 45. p

A wheel, 32, on the shaft 19, is provided with a cam-path, 33, into which projects a stud from a bar, 34, which carries the awl for piercing the leather.

On the frame 0 is a short rock-shaft, 35, an upper arm, 73, of which is in contact with a cam, 36, on shaft 19, and the lower end, 74, has a pawl, 38, .which moves the feed mechanism for the strip. It is provided with a spring, 60, for holding the roller to the cam and rocking the pawl. The spring-pawl is supported in a stud on the lower end of the lever and in engagement with a ratchet-wheel. 29, on the upper end of a shaft, 30, which has its upper bearings in a plate, 31, and its lower in the bracket 9 on the frame 0.

Between the bearings is a pinion, 33, in mesh with pinions 34 and 35 on vertical shafts 36 and 37, which have their bearings in the bracket 9. This bracket is chambered out to receive feed-drums 38 and "39 on the shafts 36 and 37, respectively. I

In the face of the bracket g is a shallow channel, 40, for the peg-strip, and the feed-drums, which are properly roughened or spurred to take hold of the strip, project a littleoutside the surface or bottom of the channel. The feed-rolls are both turned in the same direction by the pinion 33, and the parts are so adjusted as to bring the'strip forward at one movement a distance equal to the width of a peg.

ne side of the channel for the pegstrip is made movable, and consists of abar, 41, an enlarged part of which fits a chamber in the bracket, and is opposite a slot, 42, through which a set-screw, 43, is inserted into the enlarged part, whereby the bar may be set and held in any desired position, so as to prevent the peg-strip from rising from its position in the channel.

Across the channel for the strip is a path for the knife 28. The part of the bracket containing the channel is set-back at an oblique angle to the part which guides the knife and awl and driving-rods, so that the strip is split obliquely to properly form the pegs. The strip is held in the channel by means of a hinged plate, h, which covers the face of the channel. This plateis provided with a springplate, 46, held by a spring, 47, and adjustingscrew 48 against the pegstrip. The hinged plate is held closed by means of a pivoted stud and thumb-screw, 55. From the cuttingknife path the channel extends to the path of the driver 45, in which path it terminates, and when a peg reaches this path, being forced along by the advancing pegstrip and the cut pegs between, it is brought under the driver, which, as it descends, forces the peg through a hole, 84, in the bottom of the channel and into the heel-blank.

The bracket also is provide ith a guidehole for the awl 49, which is attached to the bar 34, operated by the cam-groove, as hereinbefore explained. A second awl may also be set in the bar in line with a second guidehole, 52, to be used when larger heel-blanks are made. Then the awl is inserted in the holder in line with the second hole, and the cam 15, on shaft 3, is changed for one having higher faces, adapted to throw the framethe space required.

It will be borne in mind that the peg-driving mechanism is in position on the rear of the machine, so that, when one of the dies is in place at the front and in process of filling, the other is under the pegging mechanism. The parts are so arranged and timed that as soon as the die is in place under the pegging mechanism the awl descends and pierces the blank. Then a high part of one side of the cam 15, on the mainshaft3,comes,byhalf-revolution,intocontact with the roller on the fixed arm and moves the frame laterally far enough to bring the driver with the peg in its path directly over the holejust pierced by the awl, and in this position the bar of the driver is dropped by the cam and forced down by the spring to drive the peg while the knife is cutting another peg. At the same time the awl descends, by reason of the sh aft moving twice as fast as the shaft 3,and makes a hole while the peg is driven in the first. The driver and knife are immediately lifted, and the frame is moved a step farther by completion of the revolution of cam 15, bringing the other and higher part thereofinto contact with the roller of the fixed arm, and the driver and peg are brought to register with the peghole last made, and the driver again descends and drives the second peg. The highest part of the cam 15 having passed the roller, the spring returns the frame 0 to its original position, and the mechanism is in readiness for a repetition of the operation.

As soon as the operation of pegging is finished the clutch is released from the drivingwheel on the main shaft,and the pegging mechanism remains quiet until the table has brought another blank around to its place.

In order to prevent any accident to the hands of the attendant, I have raised the die above the surface of the table and provided a collar, m, surrounding the same. The rear of this collar is inclined, as at m, so that the blank, as it is pushed off, slides down without turning over.

I have also improved the machine shown in the aforesaid patent in respect to the devices for conveying the blank to the pressing mechanism, and have devised means for holding the blank in accurate position to be pressed. This part of my invention is shown in Fig. 3. The position of the press is indicated at S and the conveying-arm at T. They retain the relative position which they held in the patent above referred to and, with the exception of some immaterial details of workmanship, are the same as the devices shown in the said patent, and are operated by similar mechanism.

Secured to the frame A is a bracket, which projects out over and above the table and is provided with two arms, which form bearings for the reduced end of a clearingarm, P, which has a depending plate upon its lower surface. This clearer has easy movement in the arms of the bracket, and between the arms a spiral spring is placed, secured at one end to the bracket and at the other to the journal of the clearer 1?, thus putting a tension upon the said arm and tending to keep it in its nor mal condition, or return it thereto when, as hereinafter described, it is moved therefrom. A bracket seen red to the press-frame supports a vertical shaft, a, to the end of which an arm is secured carrying a compound arm, B, one part of which serves as a guardplate for the outer circumference of the pressplunger, while the other serves to remove the blank from the plunger at the proper time.

After the blank within the die has been nailed, and the table begins its movement to the front, the ejector forces out the blank, and when it reaches the clearer 1? the blank is prevented from further movement to the front as it comes in the path thereof, while the die passes beneath it. If there is any pressure upon the depending plate, the clearer will turn in its hearing until the die has passed entirely from beneath it, when the spring will immediately return it to its normal position. As the blank is pushed from the moving die the con veyingarm swings around and conveys the blank to the pressing mechanism in accurate position against the guard-flange. The blank is then pressed and the movements of the various parts are so timed that as the presspiston descends to its normal position the shaft a is given a partial rotation, the guard-flange is moved to the right, and the opposite arm swings across the bed of the press, removing the blanks to a basket or receptacle set to receive them. i

In Fig. 12 I have shown suitable mechanism for operating the conveyerarm. This arm is upon a shaft having its bearings in an offset of the frame of the machine surrounding the revolving table. This shaft has a gear, 6, secured to it, into which a rack, a, meshes, to move the conveyer-arm over the table in conveying the heel from the die to the press. The rack is held in place and guided bya part of the shell or casing of the offset. The end of the rack is rounded or beveled and extended into the space between the table and the surrounding frame, and in this position the conveyer-arm is in its normal position. In the movement of the table a cam, c, or swelling is brought opposite the end of the rack, and in the continued movement of the table the said cam forces the rack back, thus operating the conveyer-arm to throw it inward over the table, as hereinbefore explained. After thecam on the table has passed this point, a spring, d, on the shaft of the arm retracts the said arm and causes the rack to assume its former position.

In Figs. 13 and 14 suitable mechanism is shown for operating the discharge-arm. The shaft 02 of this arm, as shown in Fig. 13, carries a gear upon its end which meshes with a rack, a, moving in suitable guides. This rack has a springprojecticn, p, secured to it, which is struck by a projection on the arm, which moves the toggle-levers of the press. This arm derives its motion from a pin set in the face-plate r, secured to' the shaft 9. This shaft is connected by shafts and gears to the main driving-shaft in theusual way. After the rack has been operated and the shaft it turned so as to discharge the heel in the press, a spring, 8, on the shaft returns the dischargearm to its normal position.
