Spccication forming part of Letters APatent No. 76,975, dated April 21, 186,8.

To all whom it may concern: y y

Be it known that we, HAZEN J. BATCEEEL- DER and GEORGE E. WOODS, of Marlborough, in the' county of Middlesex and State of Massachusetts, have invented a new andA useful or Improved Machine for Making Horseshoes; and we do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which-V l Figure l is a topview, and Figs. 2`and 3 are vertical and longitudinal sections of it, theybeing taken so as to showthe mechanismen opposite sides of the plane of section. Fig. 4 is a vertical section of the creasing and punching mechanism. Fig.5 isa horizontal section of the bender taken below its cap-plate.

In the drawings, A denotes the bender applied to a slider or carriage, B, which is ar ranged between parallel guides C C, constituting the top parts of the frame or table D, by which the operative parts of the mechanism are sustained.

The space a between the guides C C opens into a square space, b, sunk in the guides C C at their outer ends, and being open at its front end. This space b serves the purpose of disconnecting the horseshoe from the bender after the blank may have been carried between the two rollers E E. The heels of the bent blank will drop from the bender in the space a, and will be estopped by it during the retreat ofthe bender. The bent blank will be expelled from the space b by the carriage B during the next advance.

The bender gradually increases in width from its toe to its heel, as shown in Fig. 5, so that, during the bending of a blank by means of it and the rollers E E, each half of the blank shall be formed tapering from its quarter to its heel. The subsequent operation of creasing the blank will cause the heels to curve or bend inward.

The bender is provided with a cap-plate, d, which is fastened upon and projects beyond its edges laterally, as well as longitudinally, so as, with the iianges c c of the wheels E E, to hold the blank down upon the table during the operation of bending the blank.

Forimparting areciprocatin g rectilinear motion to the carriage B and the bender A,such

carriage has a connecting-rod, f, extending from it to a bell-crank, g, projecting from a driving-shaft, h, carrying a iiywheel, t', and a driving-pulley, lr. u

The shaft hkhas two cams, l m, iixed on it, they being toactuatetwo levers, FG, arranged over thel table in manner as represented. One of these levers-wiz., that marked F-,carries a shear or cutter, n, to operatewith `a stationary shear, o, fixed on the table, and opposite to a stop-gage, parran ged as represented.

VThe otherlever, G, carries a creasing-punch, p', and a nail-hole punch, r, which are arranged over a bed, s,'provided with an adjustable gage, t. Another or auxiliary nailholepunch, u, works up through thesaid bed, and projects from another lever, o, which is arranged, with reference to the lever G, in manner as shown in the drawings. During the descent of the front or shorter arm of the lever G it, by its pressure on the rear arm of the lever c, will move such lever so as to force its punch upward.

Within the tail or long arm of the lever G a cammed lever, w, is arranged. lt turns on a fulcrum, m, extending through it and the lever G, and has its cam z resting on the cam directly under the said lever G. To the longer arm of the lever w one end of a spring, y, is applied, the other end of such, spring being connectedto the rear end of the lever G. The rearmost position of the lever w, or that into which it will be drawn by the spring, is shown by dotted lines. When the lever wis in such position the creasing and nail-hole punches of the lever G will be so raised above the lbed s as notto pass into a horseshoe when placed thereon and the lever G is in operation.

Attached to the cammed lever is a cord, a', which is led forward toward the front end of the lever G, and when drawn back and hitched upon a stud or staple, b', causes the cammed lever to take the position exhibited by full black lines. This will so elevate the tail of the lever G and depress its front arm that, during the revolution of the operative cam of the lever G, a shoe, when laid on the bed s and placed against its gage in a position to be subjected to the action of either the creasin g-punch or the nail-punches, will be punched thereby.

The object of the auxiliary nail-hole punch is to prevent the nail-holes being formed with burrs at their lower'ends, as they are likely to be when one punch only is employed in their formation.

In operating with the above-described machinehan attendant takes a bar of iron and passes it between the shear-cutter n and its fellow o, so as to cause the end of the bar to abut against the stop p. The shear n will next descend and sever from the rod a blank or piece of proper length for the making of a horseshoe. Next, the bender will advance and touch the blank at its middle, and will force the blank against and between the periphery of the two rollers, by which it will not only be bent around on the bender, but will be swaged or tapered from its quarters to its heel. Next, the blank will be advanced over, and so that its heels may drop into the space b. Next, the l ter being so punched and creased, may be held and guided or moved by the hand of an attendant, or by tongs or the proper implements. Thelower or auxiliary nail-hole punch operates at the same time with the main nail-hole punch, and should be arranged a little aside of it, as shown in Fig. 6, which is a transverse section of the two, v'the same being to enable the points of the punches to pass byeach other without coming in contact While the punches are in the act of completing a nail-hole. The under side of the cap-plate of the bender is not parallel with the top of the table, but is set so as ,to rise a little from toe to heel, in order to' enable the tapering of the shoe from its ilanks to its heels to be accomplished.

We claim- 1. The combination and arrangement of the recess b with the carriage B, bender A, and rollers E E, formed and arranged substantially in manner land so as to operate as described.

2. The combination and arrangement of the cutting-shears n o, the stop-gage p, the bender A, the rollers E E, and the discharging-recess b, the whole being to operate as set forth.

3. The combination, as well as the arrange ment, of the auxiliary nail-hole punch u and its operative lever c with the bed s and the main nail-hole punch 'rand its operative lever G.

4. The combination ofthe gage t the bed s, the creasing-punch, and the lever 5. The combination of the cammed lever w with the operative cam m of the lever G, and with such lever Gr, provided with one or more punches,arranged to operate with a bed, s, in manner as described.
