DAVID J. FARMER, OF PENN YAN, ASSIGNOR OF ONE HALF TO B. NELSON GERE, OF SYRACUSE, NEW YORK.

HORSESHOE-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 331,626, dated December 1,1885.

Application filed April 29, 1885.

To all whom it may concern:

Be it known that I, DAVID J. FARMER, of Penn Yan, in the county of Yates, in the State of New York, have invented new and useful Improvements in Horseshoe Swaging Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The purpose of this invention is to impart 1c the final finish to horseshoes which have previously been bent and brought approximately to shape.

The invention consists, chiefly, in the employment of shoe-holding dies and swages 1 mounted on arotary carrier, and an oscillatory arm carrying a flattening and compressing die in position to impinge the horseshoe carried by the dies of the rotary carrier, and a rotary plating-die, all combined with mechanism to produce a succession of action or operation on the metal in forming the shoe by the continuous movement in one direction of the rotary carrier, and thereby save much time and produce better results in the manufacture of horse- 2 5 shoes.

The invention also consists in novel means for guiding the die carried by the oscillatory arm, so as to cause said die to bear with uniform pressure on the entire surface of the 0 horseshoe; and the invention furthermore consists in certain auxiliary devices employed in connection with the aforesaid rotary diecarrier and oscillatory arm, all as hereinafter more fully described,and specifically set forth 5 in the claims.

The differentiating features of this invention over that described and shown in another application of even date herewith consist in the movement of the die and former carriers entailing different organizations of the machine.

In the annexed drawings,Figures1 and 2 are elevations of opposite sides of my improved machine. Fig. 3 is an end view of the same, with a portion broken away to better illustrate 5 other parts situated at the rear of said broken portions. Figs. at and 5 are vertical longitudinal sections taken, respectively, on lines no at and 3 3/, Fig. 3; and Fig. 6 is a vertical transverse section on line .2 z, Fig. 5.

Similar letters of reference indicate corresponding parts.

Serial No. 163,862. (No model.)

A represents the supportingframe of the machine, said frame consisting, mainly, of two rigid parallel upright walls rising from a base or bed plate, by which latter it is firmly se cured in position. In said walls arejournaled two shafts, B and B, one of which has affixed to it the driving pulley or wheel WV, balancewheel W, and a pinion,V, which latter meshes in a gear-wheel, U, fastened to the end of the other of the aforesaid shafts.

Between the two walls of the frame A is arranged a rotary die-carrier in the form of a wheel, 0, fastened to the shaft 13, on which wheel are mounted the dies h and t, which 6 5 hold the horseshoe to be operated upon, the central die, h, being fitted movably in a radial channel in the wheel 0, and held yieldingly protruding at the periphery thereof sufficiently to hold the horseshoe which embraces the said die. The die i surrounds the die It, and is rigidly secured in a countersink in the face of the wheel 0, and serves to resist the pressure of the swaging and finishing die hereinafter described.

At opposite sides of the die tare jaws f, which yield laterally and endwise, and are adapted to press against thesides of the horse shoes held on the die h. Said jaws are provided at their outer sides with'cheeks or rollers g,which, in the rotation of the wheel 0, encounter cams G on theinner sides of the frame A, and thereby cause the jaws f f to be pressed against the sides of the horseshoe, as aforesaid, said pressure serving to swage or thick- 8 5 en up the heel of the shoe and prevent the shoe from spreading while subjected to the pressure of the flattening and compressing die. The flattening and compressing die (designated by the letter is in the drawings) is car- 0 ried in proximity to the aforesaid shoe-holding dies, so as to impinge and thus flatten the shoe simultaneously with the swaging of the same. The die It is oscillated synchronously with the movement of the rotary carrier 0 by 5 an arm, D, to which said die is secured, and which is arranged radially to the wheel or rotary diecarrier 0, and hung on trunnions journaled in the side walls of the frame A, one of said trunnions projecting at the outside mo of the frame, and having affixed to it a crank,

H, which receives an oscillatory motion by a pitman, I, connecting said crank with awristpin, Z, on a wheel, L, fastened to the shaft 13, as shown in Fig. 20f the drawings.

In order to obtain auniform pressure of the flattening or compressing die on the entire surface of the shoe held by the dies of the rotary carrier 0, I make the oscillatory arm D flexible by providing it with a joint, m, and aflixing to the lower section of said arm a laterally-projecting arm, E, the free end of which is connected with and supported by the standards F F,which serve to guide the arm E, and thereby control in the line of motion the face of the die 70. The standards are arranged adjustably in relation to their distance from the rotary carrier 0 by means of plates (2 d, fastened to the base of the frame A, and having avertical flange provided with a horizontal slot, e, for the reception of the pin or bolt by which the foot of the standards is connected to said plate, as shown in Fig. 5 of the drawings. The connection of the arm E with the standards is also made adjustable by providing the upper end of the standards with aslot, a, which is vertical, and through which the wrist-pin b of the aforesaid arm passes. Said slot allows the aforesaid connection to besihifted and secured in position by nuts on the ends of the. wrist-pin b, so as to obtain the proper motion of the arm E, to carry the die It with uniform pressure across the shoe held on the dies of the rotary carrier 0.

If desired, the arm E may be made self-adjusting to allow the die k to conform to the surface of the shoe by leaving the said arm loose on the standard,and supporting it by springs c c in the slot (1, above and below the wrist-pin b. I do not, however, limit myself specifically to the employment of the standards F, as shown, inasmuch as the arm E may be supported by a hanger arranged above said arm.

M denotes a hub fastened to the shaft B in range with the wheel 0, andhaving secured to its periphery a die, a, which impinges and plates out the shoe carried by the wheel 0 during the rotation of the said hub and wheel. A bar, N, is secured across the front of the frame A and arranged to sweep the completed horseshoe from the wheel 0, the shoe being released from the holdingdie h by the retraction of said die caused by a cam, P, on the inner side of the frame A,which cam is encountered by a roller, 0, on the end of a stud-pin projecting from the side of the die and through the wheel and jaw. The said bar Nalsoserves to press the side jaws, f, endwise even with the face of the dies, toclear the jaws from obstruction when the shoe is drawn off.

The operation of my invention is as follows:-

The shoe is placed by the operator on the die mounted on the rotary carrier 0 in frontof the oscillatory die. Said carrier in its continuous motion in one direction passes the first point of impulse given the side jaws, f f, by the cams G, which swage the ends of the shoe, and at the same time the oscillating arm D is carried into action, and the flat die thereof is brought to bear on the shoe toflatten or compress the surface thereof. As the shoe is carried from the first and second action of the machine, the side jaws again receive the impingement of the cams G on the sides of the machine. A second swaging of the shoe takes place, and in the further rotation of the die carrier or wheel the shoe and jaws are again brought between another set of the cams G, and then the rotating plating-dien engages with the face of the shoe. At this point the operation is completed, and the shoe is subsequently dragged off by the bar N. As there are several dies on the carrier or wheel, it is obvious that more than one shoe may be operated on during one revolution of the rotary carrier.

If found desirable, the machine may be arranged to bend, crease, and finish the shoe from the bar by applying suitable mechanism for bringing the iron or straight blank in position for the former mounted on the rotary carrier or wheel, and arranging creasingtools in the die carried by the oscillating arm 1), or, if found preferable, may be arranged in a rotary die, n, which completes the operation of forming the shoe.

Having described my invention, what Iclaim as new, and desire to secure by Letters Patent, 1s
