SPECIFICATION forming part. of Letters Patent No. 342.278. dated May 18, 1886.

(No model.)

To all whom t may concern:

Be it known that I, EDWIN E. BEAN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, haveinvented certain new and useful Improvements in Pegging-llachines, of which the following is a specification.

My present invention relates to improvementsin pegging-machines for boots and shoes, substantially of the character shown in Letters Patent No. 135,681, to Erastus VoodWard; and it consists in improvements of machinery of that character, whereby its efliciency and usefulness are increased.

In machines of this class the work is held or supported on what is called a horn, this horn being adapted to be swung partially or entirely around, so as to present all parts of the Work successively to the action of the machine.

In the operation of the machine a hole is first punched in the work andy a wire peg is cut off by themachine to a certain length from alonger piece of Wire. Then this peg is carried over to and drivenin the hole and there headed, clinched, or set, so as to make a secure and firm fastening. Finally, the Work is fed along aproper distance for the next hole to b punched.

My present invention relates mainly, first, to improvements in the apparatus for feeding the Wire and cutting off the peg; second, to improvements in the apparatus for carrying the cut peg under the driver and driving it; third, to improvements in the mechanism whereby the necessary motions are given to the punching and driving tools, and, fourth, to improvements in the construction of the machine whereby a clinching or heading of the peg on the inside is accomplished in a more effective manner than before.

Figure 1 is a side elevation of my machine. Figs. 2, 3, 4, 5, 6, 7, 8, and 9 are details of different parts. Fig. 10 is an enlarged side view of the upper part, taken from the same side that Fig. 1 is taken. Fig. 11 is an enlarged side View of the upper part, taken from the side opposite to that of Figs. 1 and 10. Fig. 11a is a detail'showing the cam and its immediate adjustments for operating the headof the upper part of my machine. Fig. 13 is a detail. Fig. 14 is an enlarged front view of the upper part of my machine, a part of the sliding plate being cut out, so as to show the recess on its rear side and the cam that works it. Fig. 15 is a plan view of a part of the head ofthe machine. Fig. 16 is an enlarged side view of a part shown in Fig. 11, and relates particularly to the wire feeding and cutting-oft` mechanism. Fig. 17 is a section on line a: x of Fig. 16.

The shaft B is the main source of power in the machine, powerbeing applied through the pulley B. The up-and-down motion of the awl, the carrier D', which is also connected with and moves up and down the mechanism for feeding and cutting off the peg-wire, and of the driver and driver-bar E E is derived from a rocker arm or lever, C3, mounted on the auxiliary rockershaft C', which is rocked from the main shaft by the lever C2, Working in a camvgroove on the wheel-cam C. This is best indicated by dotted lines in Fig. 14. The to-and-fro motion of the awl and driver,whereby each is brought successively over the work at the point where the peg is to be driven, is obtained by mounting them in a sliding car riage or plate, (best shown at A", Fig. 10,) which is slid back and forth by a cam, B2, mounted on and driven by the main shaft, also by means of a lever, H, operated by the motion of the plate A2 and connected at its outer or moving end with a second sliding plate, H". This second plate, which is perforated at H5 to receive the cut peg and acts as a carrier for it, is brought up to and carried back from the proper point over the Work to deliver the 'peg in place under the driver to be driven into the hole previously formed by the aWl, and is then carried back to receive another peg. The heading or clinching action, which should occur simultaneously with the driving of the peg, is also obtained from the main shaft B by means of the cam-wheel P12, lever P, (see Fig. 11^,) mounted on the auxiliary shaft G, connecting-rod P, and system of bell-crank levers, (best shown in Fig. 1,) causing a moving anvil or clincher, M, to come up through the horn'and meet the inner end of the peg, thereby clinching it.

ing device. Fig. 12 is an enlarged rear view The timing of the machine is as follows:

IOC)

The first operation is the feeding of the wire and cutting off of the peg, and simultaneously the punching of a hole through the work; second, the withdrawal of the awl and the return of the peg-feeding mechanism to its highest point, third, the lateral movement of the awl, driver, and cut peg, whereby the awl is moved away from its position over the hole in the work, which is taken in turn by a carrier containing the cut peg, the driver at the same time being brought into a position immediately over the peg to drive it into the work; fourth, the driver descends, and a't the same time the clincher ascends to Ldrive and clinch the peg, after which the driver is raised or withdrawn; fifth, the peg-carrier, awl, and driver are returned to their original positions, and the work is simultaneously fed forward a distance corresponding to the interval between two pegs.

I will first describe the mechanism for feeding the peg-wire and cutting off the peg, and also in connection with it the device whereby I insure the automatic regulation of the length of each peg to correspond with the thickness of the work at that point where the peg is to be driven. The bar Ct, Figs. 14 and 16, as it ascends, acting through the toggle C5 C, Fig. 16, causes the levers G C, which swing upon a pivot, C7, to open the jaws C CH, and thus be freed from the wire. Now, the continued 1no tion (the wire being held by a friction-pawl, c', Figs. 16 and 17) of the bar C* will draw the jaws G8 C8 up to the required distance for a feeding-down action. This feeding-down action is effected by the movement of the arm D, which is secured to the awl-bar D', Fig. 14, the end of which passes into a slot, el, in the bar Gt, and thus causes the said bar C4 to move up and down with the awl-bar D', except that in the beginning of the downward stroke the bar C* does not begin to move, as the slot c2 is longer than the arm D is wide. In other words, Ihave provided what is called lost motion.77 As the bar C* moves down, it, acting through the toggle C5 C, moves the levers C" C downward without closing thejaws C8 Us, as the guides C9 G" on the adjustable plate MT prevent this action; but as soon as the lower ends of the toggles G5 C5 have descended below the guide-pieces C9 C, then they are free to open the levers C C", and thus cause t-he jaws Cs C8 to grasp the wire suciently to feed it downward. This grasping pressure remaining the same until the upper ends of the levers C C have passed below the studs G1 C1", then the levers C C are free to be expanded by the toggle action ofthe toggles G5 C5, and thus close the jaws Cs C8 with different motion to cut off the wire. The function of the guide-pieces C9 is to regulate the feeding of the peg-wire just the proper distancel to give a peg which shall correspond in length with the thickness of the work at the point where it is to be driven, and I will now describe the mechanism by which this is accomplished. As has been said, the gripping action of the levers Cn 'fixed position.

will not comeinto play until they have passed beyond the guides C". These guides are connected through the plate MY with a sliding rod, M, operated by a link, M", worked from a rockershaft, M, which in turn is rocked by an arm,1 u, attached to and driven by a connecting-rod, K. This is illustrated in Figs. 1, 11, and 16. The lower end of this connecting-rod K" is carried upon onearm of a lever, K6, the other end of which carries the standard K', by which the horn K, which carries the work,is raised and lowered. (See Fig. 1.) It is therefore obvious that through the connections described the amount of depression of the horn K from' its highest position to correspond to the thickness'of the work produces a corresponding amount of elevation of the guides C", and therefore a corresponding regulation of the height at which t-he feeding of the peg-wire begins, and consequently the length or extent of such feed.

From the above it may be seen that the length of the wire fed .down at each motion is governed b v the distance of the guides C G9 above the studs Gm C1", since the grasping action takes place when the toggles are released from the guides U C, and the cuttingotf action takes place when the upper ends of the jaws G C have passed below the studs C10 Cl". This feeding and cutting-off mechanism slides in agroove made in the piece A5, Figs. 16 and 17, which is secured to the main frame of the machine by screws AT AT A7, Fig. 16. This fixed piece serves also to hold the stud Ain a This stud A", in combination with the spring S, holds the friction-block A8 against the sliding plate A and presses it (the sliding plate Al) against the fixed way A, so that the whole wire feeding and cutting mechanism is held in place, unless forcibly acted upon by the positive motion of the machine.

The same downward movement of the lever C3 which feeds and cuts a peg drives the awl through the stock to form a hole. This is accomplished by the following mechanism: The outer end of the lever C" carries a pin, d?, and when by the movement of the plate A4, as above described, the awl-bar D has been brought in position to drive the awl through the work to punch the hole, this pin d'2 lies within a slot, d, in the awl-bar, which is arranged to slide vertically up and down through the plate A, which carries it. The machine being so timed that the awl-bar is up when the feeding of the wire begins, the same down ward motion of the lever C3 which causes the feeding and cutting off drives the awt-bar down through the work, and the upward motion of the lever C withdraws it from the work. The hole now having been punched and peg cut off, the next operation is to convey the latter, and also the driver E, to a position where they shall be in aline over the punched hole, so that the descent of the driving-bar shall drive the peg. The peg, when cut, enters a slot or hole, IP, in the slide H2 I CU ITO

The same motion which carries the awl out of place and the driver into place over the punched hole .in the stock also (by reason ot' the action above mentioned, through the lever H, attached to the plate A4) carries the slide H" over and upon a xed base-piece or guide, H, until the hole H5 stands over a similar hole, H1 in the piece H, (see Fig. 17,) through which the awl has descended to punch the hole in the work. Then the descent of the driverbar E drives the eut peg into the work, and the simultaneous ascent of the clinchingblock N clinches or heads the peg on the inside.

I will now describe the mechanism by which this motion of the driver-bar and clincherblock is obtained. The driver-bar E, like the awl-bar D', is arranged to slide vertically in the plate A.v The drivel-bar is provided with a slot matching the slot d3 in the awl-bar, before described. The lateral motion of the plate A* which brings the driver-bar in position over the hole in the work also brings the slot in the bar into engagement with the pin d2 on the lever C. Consequently the second stroke of this lever C depresses and raises the driver-bar in the same way that the tirst operated the awl. During the operation of the driver-bar, however, the wirefeeding mechanism is at rest, being disconnected from the lever C3.

Simultaneous` action of the clincherN is accomplished in the following manner: In operation the boot or shoe is placed upon the upper end of the horn K, with the edge under the feed-wheel I and against the gage G, and there held by the pressure of the spring Kl, acting through the rod K, foot-lever K, and links Ki' K3, attached to the collar k, Figs. l, 2, and 3, and standard K. The upper end of this horn K adjusts itself to the thickness ofthe sole, but is not held rigidly in its vertiealposition, except when the. shoe is being acted upon by the awl, peg inserting or heading operation. When these are all accomplished, then the horn is freed, so that the shoe-feeding motion may take place. The mechanism for thus fastening' and freeing the horn consists in a device which locks and unlocks the rod K, this rod K" con trolling the horn through the foot-lever K. This mechanism consists of a collar, L, Fig. 12, which surrounds the rod K, and is held with a slight elasticity by means of springs L2 and L", so that its motion is very limited. The object of allowing this limited motion of the collar L is to prevent au absolutely abrupt check ofthe motion of the horn. Vhen the grip-lever L" is raised up, the rod K can move freely up and down, subject only to the action of the spring K1", Figs. l and l0; but when the grip-lever LVl is thrown down it causes the collar L to seize upon the rod K", and thus hold it, and through it the horn K. Motion is given to the grip-lever L by means of the link L", which is pivoted to it by the pin p. The upper end of the link L"h is attached to a lever, L, by a pin, Z, Figs. ll and 12, which in turn is operated by the cam LS,

which acts through the pin L7 and gives the desired movement to the lever L6. 1

I will now describe the heading device. This consists of a quadrant-shaped block of metal, N, which swings on trunnions n2 n2, Figs. 4. and 6, and is provided with a projection, N', the upper end of which projects through the opening N2, Fig. 4, so that it may come flush or slightly above the uppersurface of the horn. n is a ridge formed on the piece N, and is intended to tit in the groove n', Fig. 4:, so as to form a steady-piece. N3, Figs. et and 5, is a lever, the upper end of which rests against the back or underside of the hammerpiece N, and is so proportioned that when the small part N4 otl the hammer-rod N5 is in the position shown in Fig. 4 it will allow the hammer-piece N to fall back, as shown in Fig. 4;

` but when the hammerrod N5 moves upward it will throw the lower end of the lever N backward and the upper end forward, so astto throw the hammerpiece N nearly into the position shown in Fig. -that is, into such a position that the ha mmcrrod N5 N4 can come immediately under it and give it a sutiieient blow to head thepeg. Mot-ion is communicated to the hammerrod NA1 N5 by the lever' N, which swings on the pin Nl. The end N8 ot"Y the lever N is connected to the rod N" by nuts, which allow the horn to swing without turning the rod N This rod N9 is attached to a lever, Nm, swinging upon the pivot P in the foot-lever K (See Figs. 1 and 9;) The lower end ot' the bell'crank lever N1 is connected by a link, P2, and a pivot, P3, to the lever I, which swings upon a pivot, K8, which serves for both the foot-lever I i and the bellcrank lever P". To the end of the lever P, I attach, by means of the pin P", a vert-ical rod, P, which passes up through the center of the main standard A ofthe machine. The mechanism for operating this rod Pi is shown in Fig. 1l^. The upper end of the rod PG is attached by a forked piece, P7, and the pin PS to the lever Pi. This lever P has attached to its lower part a projection, Pl, which works in a cam-groove, P".

Instead of permitting the ham mer or clincher N to swing so far back as to require a special part-such as N'l-to bring it into place, I torm it, as shown in Fig. S, with ashoulder to arrest its motion when it is swung su'liticiently ihr back to be out of the way ofthe awl, and yet while it is still within the line of motion of the hain1nerrod. This is one of several modifications that may be made in the mechanical embodiment of this part of my invention, which I believe to consist., broadly, in combining with the hollow horn swinging in a circle around its standard an interiorly-located hammer or clincher, which is so constructed that it may be brought up every time squarely upon the end ofthe peg and in direct opposition to the downward blow of the peg` driver. In all previous devices ofthis charac ter the construction has been such that at cer-A tain portions of the work, owing to the angle at IOO IIO

IIS

which the hammer or clincher was presented to the head of the nail, it has been impossible to give any other than a glancing blow, and in consequence the work has been very imperfectly performed. By my present invention I entirely obviate this difficulty, and thereby furnish an important improvement in machines of this class.

The final operation is to feed the work along into place for the next hole to be punched, and I will now describe the mechanism for doing this: I represents the feed-wheel, which is op erated by a ratchet, l', and pawl I2, Figs. 16 and 17, the pawl I'l being attached to the slide H4 by a pivot, I3, and operated by a spring, I5, Figs. 14 and 17, and limited in its motion bya check-block, I4, Fig. 17. G, Fig. 14, is aguide and an auxiliary feeding device, it being attached to the sliding plate A4, so as to slide forward at the Sametime, although not in accord with the feed-wheel I-that is, the friction on the guide G will not be so much as though it were a stationary guide, the slip being reduced about one-half.

To retain the awl-bar D and driver-bar E in their highest position when not in engagement with the pin cl2 on the lever-C3, a pair of ribs or projections, E2 D3, are provided, one of which, D3, enters the slot in the awl-bar Df, and holds it up when the driver-bar E is engaged by the pin d2, and the other of which, E2, enters the slotin the driver-bar E, and holds it up while the awl-bar is being held up by the same pin. llhe location and arrangement of this detail are best shown at Fig. 17.

I claim- 1. The combination,with the revoluble horn K, having its upper or working face perforated, of an interiorly located hammer or clineher pivoted thereto,and arranged to swing into and away from the perforation in the horn, as set forth.

2. The combination of the horn K, having a perforated workingface, a swinging hammer a simultaneous to^and-fro movement of the awl, driver, and peg-carrier is obtained, substantially as set forth.

6. The combination,with the horn K and its support or standard K, of the lever K6, carrying the standard and connecting rod K9, rockshaft M', vertically movable guides C, and

rockerarms connecting the rockshaft with the connecting-rod K9, and also with the vertically-movable guides G9, whereby motion of the horn up or down will produce similar motion of the guides C9, all substantially as set forth.

7. The combination of a toggle-bar, C, the toggle C5, the pivoted grippers and cutters C, and the stud A6,whereby the continued motion of the toggle-bar operates to press the grippers against the peg-wire to feed and cut the peg.

8. The combination of the sliding plate A, lever H, sliding-plate carrier H4 H4, and perforated supporting-plate H, as set forth.

9. The combination of the hammer-rod N4 N5, lever N6, connecting-rod N", lever Nw, adjustable link P2, lever P4, connecting-rod P6, lever P, and cam P, as set forth.

In testimony whereof Ihave signed my name to this specification, in the presence of two subscribing Witnesses, on this 31st day of October, A. D. 1884.
