'HORSESHOE-SWAGlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 331,625, dated December 1, 1885.

Application filed April 29. 1885.

To all whom it may concern.-

Be it known that I, DAVID J. FARMER, of

' full, clear, and exact description.

This invention relates to a machine for swaging and finishing horseshoes which have been bent and brought approximately to shape.

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.

This invention consists in an improved combination and arrangement of the requisite swaging and finishing dies and their actuating mechanism, which imparts to said dies a combined oscillating and rotary movement, and which movements cause the dies to impart to the horseshoe an even contour and the desired finish, and at the same time producein the crease of the shoe the varied angles of depression required for the disposition of the nails to be driven at difierent points into the horses hoof.

In the annexed drawings, Figures 1 and 2 represent elevations of opposite sides of the machine. Fig. 3 is a top view of the same. Fig. 4 is a vertical longitudinal section on line a: :r, Fig. 3. Fig. 5 is a vertical transverse section on line y y, Fig. 4; and Fig. 6 is a horizontal transverse section on line z z, Fig. 5, and showing the die-carrying portion of the bed and the jaw-compressing rollers.

Similar letters of reference indicate corresponding parts.

A represents the supporting-frame of the machine, which frame consists, mainly, of stout parallel vertical walls or pedestals, on which are mounted a rotary shaft, a, and oscillating shaft b, the former receiving its motion from the main driving-shaft, as represented by dotted lines in Figs. 1 and 3 of the drawings, and the shaft 1) receiving its motion from the shaft a by a wrist on the latter, and a rock arm or crank, c, on the shaft b, and a Serial No.163,861. (No modeLl pitman, P, connecting said wrist and rock arm. On the rotary shaft a is rigidly mounted the die (I, which is designed to swage, plate out, and finish the horseshoe, as hereinafter described.

Under the shaft a is arranged a curvilinear oscillating bed, B, in the form of an oscillatory arm, mounted on ashaft, O, which is supported in the frame A. Said oscillating bed is pro- 5 vided with the usual die, f, and former e in the center of said die, and at opposite sides of this die and former are laterally and longitudinally yielding jaws g, carrying swagingdies 9, as best seen in Figs. 5 and 6 of the 5 drawings, said jaws projecting above the die f to compress the shoe around the former e, as

hereinafter explained.

The bed B receives its motion by the medium of a link or arm, D, hinged to the bed, 0 and having its opposite end bifurcated and formed with hooks h, by which it is detachably connected with trunnionst'on the free end of a rook-arm, E, attached to the oscillatory shaft 1). By means of a lever, Z, fulcrumed on 7 5 the frame A, and havingan arm, l, engaging with a pin, m, which projects from the side of the link D, said link can be raised to draw the hooks it out of engagement with the trunnion 1i, and thus deprive the bed B of its action without stopping the movement of the other parts of the machine.

r r designate rollers pivoted to slides n, which are supported'in boxes 0 in the two inner sides of the frame A, and are movable at right angles to the bed B. Set-screws 8, extended throughthe aforesaid sides of the frame and bearing on the end of the slides it, serve to adjustably confine said arms in their position.

Ido not limit myself to the curvilinear movement of the bed B, as it is obvious that the said bed can be arranged to move rectilinearly without impairing the efficiency of its operation with the rotating die.

In operating the described machine the connecting-link D is thrown out of engagement with the rock-arm E in time to bring the bed B to lie dormant at the front end of the machine, where the operator applies to the 100 former e the horseshoe, which has been previously bent approximately into shape, and,

thus embraces said former. Then by means of the lever Zthe connecting-link I) is dropped into engagement with the rock-arm E, which imparts an oscillating movement to the bed B. In this movement the horseshoe is moved back and forth under the rotary die d, the pressure of which plates out and flattens the shoe, while the rollers r r press the jaws g 9 against the sides of the shoe, and thus compress the latter around the former e. In the backward movement of the bed B'the side jaws, g, are again compressed, and at the same time crowded forward by the impingement of the rollers M". The forward movement of the jaws carries the swaging-dies closer to the heel portion of the shoe-former, and thereby imparts a second swaging to the shoe, and prevents the spreading of the heel portion of the shoe while subjected to the action of the plating-die. At the same time the toe portion of the shoe is sufficiently relieved from the pressure of the swaging-dies g'to permit of the displacement of the metal incident to the plating out of the shoe.

In the aforesaid operation the pressure of the rotary plating-die d crowds the displaced metal from the heel toward the toe of the shoe, and thereby upsets the edges of the crease in the sh0e,so as to give it the proper angle of depression for the reception of the nails,which, in applying the shoe to a horse, have to be driven at a different angle at the toe than at the side of the hoof.

It will be understood that in the forward movement of the bed the shoe is swaged on the sides, and the heels are brought up in thickness for a calk, and in the return movement of the bed a second swaging takes place, as described, and the revolving die is brought to act on the face of the shoe for plating it out.

The degree of lateral compression to be applied to the shoe in the before-described operation can be regulated by the set-screws s, which sustain the arms to which the rollers r are pivoted.

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

1. In a horseshoe swaging and finishing ma chine, the combination of an oscillatory bed, a die and former mounted on said bed, laterally-moving swaging-jaws at opposite sides of said die and former, and a rotary plating-die over the oscillatory bed, substantially as described and shown.

2. In a horseshoe swaging and finishing machine, the combination of an oscillating bed carrying a die and former, and laterally-yielding jaws at opposite sides of the die and former, compressing-rollers at the sides of the jaws, and a rotary die arranged to impingethe shoe carried on the aforesaid bed, substantially as described and shown.

3. In combination with the oscillating bed carrying a die and former, and the actuatingarm of said bed, a detachable connecting link or arm,whereby the bed can be thrown into a dormant position during the motion of the machine, substantially as set forth.

4. In combination with the rotating die and curvilinear oscillating bed carrying a die and former, an oscillatory shaft, a rock-arm on said shaft,and provided with trunnions on its free end, and a connecting-link hinged to the oscillating bed, and having its opposite end bifurcated and formed with hooks adapted to be thrown in and out of engagement with the trunnions of the rock-arm, substantially as described and shown.

5. In combination with the oscillating bed carrying a die and former, a rock-arm provided with trunnions, a coupling-link having hooks adapted to engage the trunnions, and a lever for throwing the link out of its engagement with the rock-arm, substantially as described and shown.

6. In combination with the oscillating bed carrying a die and former, laterally-yielding jaws at opposite sides of said former, arms supported movably at right angles to the bed, jaw-compressing rollers pivoted on said arms, and set-screws for adj ustably confining the arms in their position, substantially as described and shown.

In testimony whereof Ihave hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 12th day of February, 1884.

DAVID J. FARMER. [L. s.]
