IMPROVEMENT IN PEGGiNG-MACHINES.
Specification forming part of Letters Patent No. 38,463, datedMay 12, 1853; antedeted June 30, 1862; reissue No. 6,985, dated February 29, 1876 application filed September 17, 1875.
. of the city and county of Providence, State of Rhode Island, have invented certai? new Pegging Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, forming part of this specification.
Figure 1 is a perspective view of my machine. Fig. 2 is a view of the upper part of the same. Fig. 3 is a front elevation of the same; Fig. 4 shows the cam and the slide in section. Fig. 5 is a front view, showing, the cover removed. Fig. 6 is the feeding device. Fig. 7 is a view of the driving-head, and Fig. 8 a sectional view of the same.
Similar letters of reference indicate corresponding parts.
My improvement in machines for pegging soles of boots and shoes has reference to that class capable of performing the operation antomatically by motive power.
The machine is supported upon a suitable bench or table, in such manner that the awl and driver project snfticiently to allowthe sole of the boot or shoe to be placed beneath the same, and to be operated upon without interference from the bench or table supporting the machine.
All parts are caused to move by power applied to the single shaft A, as shown in the several figures in the drawings. The awl and driver have vertical and lateral mbtion in the same planes in 'hothdirections, and at fixed distances apart, imparted to them, so that while the shaft is in motion the fastening device, which secures the sole to the bootor" shoe, is being made or cut from the material automatically fed thereto, and carried to the proper position to receive the blow from the hammer or driver.
In machinery for securing the soles to boots or shoesit is considered important that, where the fastening device is to penetrate the leather and hold the parts together by friction on the fastening, the same should be driven by a blow rather than by pressure, the leather will close more tightly around the fastening, and the fastening derice is less hello to cramp or crook in its passage.
As the awl and driver are to advance in regular order at fixed distances apart, it has been usual to place both in one stock and to drive both together. This plan is found defective, in that it is difiicult to prevent overdriving of the fastening device, especially when the awl is penetrating places in the leather which are softer than in others, since an amount of power must be applied which will overcome the resistance in the hardest places.
By my improvements the and is driven by .a positive force from the shaft by a cam,
which can be arranged to drive the awl any desired distance into the leather, while the driver is actuated by the sudden recoil of a suitable spring. 7
By the use of the dash pot or retarder the action of the spring is so governed that the fastening can be driven either even with the surface of the sole, or below the surface, as is required in channel-work, by regulating the air-cushion so as to arrest the force of the hammer at the proper point.
The and and driver are fitted independent of each other to holders or stocks, thus allowing the distance between the iiistening to be regulated as required, as the awl is attached to the slide having both a vertical and a lat eral motion, the driver-stock resting in a vertical slot in the back of the same slide.
The feed stock or foot 1), in which the and is held, as shown at a in the several figures, is secured to the vertically-moving plate b, and is furnished with a slot to regulate the distance betweenthe awl and driver, so as to produce either coarse or tine work, the owl being placed the proper distance in advance of the driver. The piece b is a flat piste, with bevelededges to fit into a dovetail-groove in the latern'ilymoving piece (3, as shown in Figs. 2, 3, and 4. The laterally-moving slide 0 plays upon a lixed guide, 0, secured per inanently to the tabie or l'rame, and is held in place by dovetail-grooves, in the manner described fer the piece 3), as seen in The driver, shown at f, is a small bar or punch of steel, or other suitable metal, fixed in the end oi a stock, by which it is raised and driven upon the ihstening device. The stock is shown at g, being a bar titted to he in a groove on the inside of the plate h. g is or made part of one or both of the rolls.
a- 'irojection or toe, Figs. 3, 4, and 7 by which .the stock g is lifted through the action of the cam i.
The driver is lifted against the force of the spring h, which forces the driver on the fastening device, and that into the sole as soon as the driver is permitted to descend by the disengagement of thetoe from the cam.
The descent of the peg-driver is controlled by the retarder, -soattached as 'to regulate the force. of the spring, toward the end-of the downward motion,=by the air-cushion in the dash-pot.
The dash-pot is seen at K, and the plunger at K in the several figures. The parts are set in motion by, the cams fitted to one endof the shaft A.
The slide-plate b, to which the and is attached, is made'to playvertically by means of the crank, the pin in of which enters a cross-- slot, m, shown in dotted linesin Figs. 3 and 7.
The piece 0 is caused to move back and forth upon its horizontal slide by the cam n, seen in Fig.5, and shown as if the slide-plate were removed. l
The cam'n, acting upon a projecting pin or I plate, Z, secured to the slide, drives the piece Qonly in one direction. It is caused to return by the force-of a recoil-spring, seen at C, Fig. 2.
The material for the fastening device is fed I along the'cha'nnel 0,'Figs. 2, 3, and 6, by
means of fluted or corrugated roll or rolls, having a roughened surface, and turned by means of a reciprocating-pawl operating upon and engaging with ratchet-wheels securet i to he reciprocating or vibratory motion .of the pawl is given by a lever made to operate at the right"time by a pin, q, Fig. 3, which plays in a crookedor cam slot, q, in saidlever.
The operation of the machine'is as follows:. The boot or shoe, as the case maybe, is supported upon a last, which is supported upon a post hinged to the floor, or the last may be held in any other way which will permit of its being carried along in the proper direction by the feed mechanism.
The position of the shoe is shown at B. The edge of the sole is to be kept pressed up against a guide-plate, so that the fastening'device may be driven in at the same distance from the edge all around the sole.
The material from which the fastening is-to be, made or cut being placed into the channel 0, revolution is imparted to the driving-shaft A,-a-nd the operation commenced at the me. The plate or vertically-moving slide 6 descends and causes the awl a to perforate the sole, at
the same time a cutter attached to b, shown at S, Figs. 3 and 7, cuts off one fastening de vice. The cam n'now arrives at the stud i, Fig. 5, and causes the slide 0 to move in the direction of the arrow. This carries 6 along, while the awl is in the leather, and the-serrated foot of b pressing against the sole, which feeds by moving the sole with it, asis shown back to the place of starting, thesole of the shoe being held meanwhile in a fixed position by means of a roughened surface-stud whieh presses down upon the sole, as seen at 1., Figs. 3 and 7. By these means the driver is ad vanced overthe fastening that has been previouslycut from the material and carried along, with its channel to its inner end, and will stand directly under the driver. 7 While in this position the toe t'will have arrived at the pin 9 on the stock of' the driver g, and will cause the latter to be lifted acertain distance. As soon as disengaged, the; spring h will act to force down the stock g,
ening device, and thus drive it through a hole *in the bottom of the feed-channel into the sole I beneath. The retarder now comes into play, as the plunger K, dropping into the dash-pot K, as the driver descends, cushions upon the Lair beneath, and thus arrests the force of the .blow toward the end of its stroke.
To regulate this partwith nicety, an escape- -hole is placed near the bottom of the dash-pot, as seen at u, Figs. 2 and 8, with a screw'stop' to cover it, so that, by screwing this stop out .or in,-the escape of air is regulated, and thus the velocity of the descent of the driver controlled. Having thus described my invention, I claim as new and desire to secure by Letters Pat- 7 .e ut 1. In a shoe-pegging machine, a reciprocating cutter arranged to separate the fastening device from the material automatically fed to said cutter,thedriver, thestock of which trav- "els between closely-fitting guides, and a spring r arranged-in direct contactwith the driver-stock, all combined substantially as set forth, whereby the driver, with its stock, is reciprocated, and acts in a direct line to drive the fastening gdevice home at a single blow by the action of the spring, substantially as and for the purpose specified. p 2.
