SPECIFICATION forming part of Letters Patent No. 408,329, dated August 6, 1889. Application fi ed May 25, 1889- Serial No. 312,088. (No model.)

To all whom it may concern:

Be it known that we, JAMES H. TAYLOR and CHARLES POVEY, citizens of England, residing at Attleborough, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in I-Iorseshoe'Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable IO others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters an d figures of reference marked thereon, which form a part of this specification.

Fig. 21 is a rear view, and Fig. 22 a section, of one of the levers P, on an enlarged scale, taken through the rolls f f Fig. 23 is a side view, and Fig. 24 a face view, of the shoe-forming die, 011 an enlarged scale. Fig. 25 is a bottom view, Fig. 26 an edge view, and Fig. 27 a crosssection, of the bar as formed ready to be fed into the machine.

The nature of our invention is defined in the claims hereinafter presented.

In the drawings, A denotes the frame of the machine supported in bearings a C6, in which is a shaft B, having fixed on one end of it a gear C, engaging with a pinion D, secured on a driving-shaft E, sustained in bearings I) b, fixed to the fraineof the machine, the said shaft E being provided with a fast pulley F and a loose pulley G.

Keyed to the shaft B and arranged cen- 7o trally thereon, between the sides of the frame A, is a bed-plate F, the periphery of which, except where it is provided with the curved bearings c 0, (see Figs. 2 and 19,) is concentric with the shaft B. The said bearings c c, of which there may be two or more in number, are arranged at regular intervals, the curved surface of each being the arc of a circle, and each receives and supportsa semicircular rocker G, having flanges e e to keep it in position in the bed-plate. Said rocker also has a notchf to receive a projection g from a supporter H, to which is secured the shoe-forming die I, as shown. Projecting from the supporter H are flanges h h, which rest against the sides of the rocker G and keep it in its due relation therewith. Pins '1 i, secured in opposite sides of the supporter H, serve as pivots for the outer ends of headed rods j, arranged within and projecting from 0 spring-cases 716, secured to opposite sides of the bed-plate F. The springs Zin said cases encircle the rods j, and are compressed between the head of the said rods and the head of the cases it, and serve to keep the faces 3 5 of the supporter H against the periphery of the circular auxiliary bed-plates U U, hereinafter referred to, and the circular face of the rockers G against their bearingsin the bed-plate. (See Figs. 2, 3, and 19.)

Supported in bearings m m in the front portion of the frame A is an eccentric-shaft J, having fixed to one end of ita gear K, engaging with the pinion D. Said gear, owin g to the fact that the bed-plate is shown as having but two shoe-forming dies, is provided with half the number of teeth of the gear C. Encompassing the eccentric portion of the shaft J is a sleeve forming part of a pitman M, its upper end being pivoted at n to a slide N, carrying the swaging devices 0 0, which operate with the abutments p p to thicken the ends of the bar of iron to form the shoe, and the pieces 0 and 13 also serve as shears to sever the said bar after being fed the proper distance into the machine, or until it reaches a gage 19 provided with means for adjusting it and clamping it in position.

A plate q is secured to the front of the machine and supports gibs 4' between it and the slide N, and has screws for adjusting the gibs against the slide to compensate for the wear of said slide and its ways. Extending from said plate (1 and resting against one side of the frame of the machine is a bracket 0, pivoted to which and so as to revolve in a horizontal plane is a series of rolls 3, (see Figs. 1, 4, 1'7, and 18,) one of said rolls being connected to a gear 2, engaging with a gear a, fixed to an arbor provided with a roll '0 and a crank-wheel 10, supported by a slide 00, which can be adjusted horizontally with relation to the rolls 5' by a screw 3 so as to cause the roll 11 to bear against a bar of iron when between it and the rolls 5 sufficiently to feed the said bar through the passage as and into the machine by turning the hand-wheel 10. (See Figs. 17 and 18.) The slide 00 is sustainedin another slide 2, which can be adjusted horizontally by a screw a in a direction at right angles to that in which the slide a: can be moved, said slide 2 having a guide I), arranged in front of the rolls 3, as shown, to keep the bar in position against said rolls, and the said slide ,2 is clamped in position in the bracket 0 by a screw 0', arranged in groove d therein.

Extending upward from the front portion of the frame is a yoke L, to which is pivoted at e the levers P P, which carry the bendingrolls ff (See Figs. 2, 17,21, and 22.) These rolls are supported so that they can freely turn on bolts f fixed to the arms by nuts g and are slightly tapering, the ends of said rolls having the larger diameter being next the levers P, and the upper ends of the said levers are drawn toward each other by a'sprin g g. The object in tapering the rolls ff is to insure the forcing of the surface of the shoe, which, when it is completed, is the top surface of it, so that said surface shall bear nearits outer edge on the face 01 of the forming-die I. (8% Figs. 23 and 24:.) cause the bar to stand with relation to the die essentially as shown in dotted lines in Fig. 23. This is done to prevent the creases in the shoe from being narrowed or partially This will.

closed while the shoe is being acted on by the hammer, it being so arranged that when the die is passing under the hammer, the hammer shall barely touch the outer edges of the creases in forcing the shoe against the face 00 of the die to incline or concave its upper surface.

Above the bed-plate F, and mounted in hearings in the frame A, is a shaft Q, the part of it between the said bearings being eccentric to the journals of said shaft, and on said eccentric is arranged a hammer R, applied to it so that it can revolve thereon. The said shaft is provided with a driving-pulley Pivoted to a rod-h, supported in bearings IL2 in the upper part of the frame A, are two gravitating arms T, which rest at their free ends (see Fig. 2) on the periphery of auxiliary bed-plates U, supported on the hub of the bed F, so that they can turn thereon. The peripheries of said auxiliary bed-plates furnish bearings for the faces 3 of the supporters H, and, together with the bed-plate F, sustain the die when the blank is forced against it during the bending of it, and also while being acted upon by the hammer R. Each of the arms T has an inwardly-projecting ledge 2", on which rests a slide V, projections is from said slide extending into slots Z in the arms T. Supported on said projections and pivoted to pins 077,, projecting upward from the slide V, are nippers WV, the tails n of which rest on the projections 70 and extend into the said slots Z in the arms T. Each nipper has a roll 0 pivoted to it, which enters curved notches p or p in the arms T when the slide V is at either extreme of its range of movement in said arms. When the slide V is in its lowest or forward position in said arms T, as shown in Fig. 2, the rolls 0 are moved into the notches p by the tails n of the nippers striking against the lower or forward ends of the slots 1 in said armsT. (See Fig. 13.) The .slide V and its nippers when in this latter position are ready to receive the shoe-forming die I with a shoe upon it, and supposing the bed-plate F to be in revolution in the direction indicated by the arrow in Fig. 2, when the advance end of the supporter H strikes the inclined portion 8 of the arms T, said arms will swing upward on their pivot into a horizontal position and bring up against stops s fixed in a yoke A secured to the frame of the machine, and the die I, with the shoe, will pass between the nippers lV,and on the advanced or toe portion of the said die striking the slide V at q'the said slide will be carried forward with the die, and as the rolls 0 are moved out of the notches p of the arms T the nippers W will turn on the pivots m, and their jaws 25 will grasp the shoe near its ends and firmly hold. said shoe to the die while the .rolls move along against the straight portion 0" of the arms T.

The arms T so operate the die-supporter H and the rocker G as to maintain the die I with the shoe thereupon and held thereto, as here inbefore set forth, in a horizontal position while passing under and being operated upon by the hammer, so that the shoe when it leaves the hammer will be straight when viewed in edge View and not curved, as are the shoes heretofore made in machines having the forming-dies supported on a bed rotative on a horizontal axis. The shoe, having passed from under the hammer, is released from the grip of the nippers by the rolls 0' swinging into the notches p of the arms T, and at the same time the toe of the shoe will slip past and be carried under the part g of the slide V, and in its downward course will meet the clearers t which are adjusted to pass between the shoe and the die and disengage it therefrom and cause it to pass down the chute X.

The chuteX is supported on a shaft Y, sus tained in bearings fixed to the frame A, and has clamped to it an arm it, provided with a setscrew ta which passes through said arm' and bears on the frame. A spring v, secured to the free end of said arm and to the frame, keeps the set-screw n against the frame and allows the chute to swing in its bearings when the die is moving in contact with the clearers. The said clearers t are secured in position by clamp-screws and nuts, as shown, which admit of their adjustment.

The bar B from which the shoes are to be formed, is represented as creased and rolled into the required shape, and when introduced into the machine is to be heated to the proper temperature to enable the forming of it to be carried on.

The operation of the machine may be thus described: The bar, having been creased, partially punched, and rolled into the required shape, as shown in Figs. 25, 26, and 27, is introduced in a heated state between the guide b and rolls 9, (see Fig. 4,) till it is gripped by the roll 1, when the attendant, by revolving the crank-wheel to, advances the bar through the passage as a proper distance or till its forward end reaches the gage p (see Fig. 17,) the bar being represented in dotted lines. The machine being in operation, the slide N will now rise and advance the swaging-dies o 0', the portion of the bar within the machine and between the gage p and the cutting-edge o of the die 0 being severed from the bar by the edge 0 and the lower end 13" of the abutment p, which serve as shears. The severed portion of the bar or the shoeblank will next be compressed between the swaging-dies p p ando o to thicken its ends, immediately following which the forming-die I will rise against the middle of the said blank, and the swaging-dies 0'0 will simultaneously retreat from it. The said forming-die I in advancing will force the blank between and against the rolls f and f successively, the former bending the toe portion of the blank and the latter the quarters and heel portions. The spring g, resisting the spread of the upper arms of the levers P P, causes the rolls f to bear the inner edge of the blank firmly against the edge of the die, and the taper of the said rolls f and f causes them to force the surface of the blank near its outer edge, which is the top surface of the shoe, against the face 00 of the die. (See Figs. 23 and 24.)

It will be observed that when the die I bears the blank against the rolls f the rocker G will turn in its bearing in the bed-plate, so as tobring the face of the said die into parallelism with the inner face of the levers P, which position it will hold till the ends of the shoe-blank pass from contact with the rolls f when the rocker will assume its normal position. The die continuing to advance, when the forward end of the supporter I-I reaches and moves against the inclines s of the arms T said arms will be raised against the stops 3 and into a horizontal position, and the toe of the die 1, meeting the part qof the slide V, will carry said slide forward and cause the nippers \V to grasp the shoe, as hereinbefore described,- and hold it firmly to the die. The rocker G, when the supporter passes under the said arms, will turn in its bearing, so as to cause the surfaces 5 of the said supporter to bear fairly against the surface 5- of the arms T, (see Fig. 19,) and this movement of the rocker in its bearing will maintain the die I and its supporter in a horizontal position while said surfaces are in contact and the shoe is being subjected to the action of the hammer B, after which the nippers will be caused to release their hold on the shoe, as hereinbefore set forth, and the surface s of the supporter being carried out of contact with the surface s of the arms T the rocker will again assume its normal po-- sition, depress the toe of the die, and carry it under the part q of the slide V. The free ends of the arms T, as soon as said surfaces 8 and .9 pass out of contact, will drop onto the periphery of the auxiliary beds U, the slide V will move forward into the posit-ion shown in Fig. 2, and the die I, with the shoe, will pass onto the clearers i which will enter between the shoe and die and release thesaid shoe from the die, so that it will pass into the chute X and be conducted from the machine.

From the foregoing it will be seen that by our improvements a horseshoe, when it passes from the machine hereinbefore described, is much nearer completion than are the shoes formed in the machines heretofore in use, provided with dies fixed in the periphery of a rotary supporting-bed, as the shoes formed in said machines are curved, as seen in edge view, and before they can be used must be subjected to a straightening process in another machine adapted for the purpose, whereas the shoes formed in our machine are straight in this particular when they leave the machine, and do not require any such treatment. Furthermore, this machine admits of the making of a rolled or a hammered shoe, and when it is desired to make the latter the shaft Q is revolved in its bearings by a belt applied to the pulley S, which will impart tothe hammer the IIO proper motion; but when it is desired to make a rolled shoe the belt is removed from the pulley S, and the shaft Q is turned in its bearings till the sleeve R is brought into the desired or proper position with relation to the die. Then said shaft is clamped in its hearings so that it cannot revolve, in which case the sleeve will turn on the said shaft and roll the shoe against its die as it passes along underneath and in contact with the said sleeve.
