HoRsEsHoE-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 513,456, dated January 23, 1894.

Application liled July Z0, 1893.

To all whom i# may concern.-

Be it known that I, HENRY E. DARBY, a citizen of the United States, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Horseshoe-Swaging Machines, of which the following is a specification.

My invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon,which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure l of the drawings is a view in side elevation of my improved horseshoe-swaging machine, broken away at its middle part to show the presser-rolls in cross-section. Fig. 2 is a top plan view of the same. Fig. 3 is au edge view of one of the die-supporting links of the endless carrier, detached. Fig. 4 is a top plan view of one of the shoe-supporting swaging-dies detached. Fig. 5 is a side elcvation of the same.

My improved machine is adapted for swaging horseshoes after the same have been formed by bending horseshoe-blanks in any p 3o known manner.

The object of my invention is to provide an endless carrier for the swaging-dies which will cause the dies to properly present the formed shoes to the presser-rolls to be swaged there` by, and afterward cause the swaged shoes to be discharged by gravity from the swagingdies. When the' swaging-dies are presented to the presser-rolls by an endless carrier movable in a horizontal plane upon drums rotary on vertical axes, with the dies secured on one side only to the carrier, as heretofore prac# Serial No. 480,986. (No model.)

sides of the respective dies, whereby the dies are properly presented to the rolls and maintained in a proper position during the swaging operation, and afterward inverted to discharge the swaged shoe from the dies by gravity.

A is the bed of the machine, the upper surface of which forms a table A on which the shoe-supporting swaging-dies B rest as they are carried to and from 'the horizontal presser-rolls O, O', each of which rolls has end -beariugs in the uprights A2 erected from opposite sides of the bed. The presserrolls are located the proper distance apart for the upper roll to bear upon a die-supported shoe when the bottom of the die rests upon the lower roll, in passing between the rolls, and properly swage the shoe, or make it conform to the shape `of the die-surface. The supporting and swaging surfaces of the dies may be of any known form. The dies are supported and presented successively to the presser-rolls by means of an endless carrier comprising the chains, D, D', supported upon and driven by drums in the form of sprocket-wheels, D2, D3 mounted upon shafts D4, D5 which have bearings in the bed A at opposite ends of the machine.

The drums are rotary on horizontal axes, parallel with each other and parallel with the axes of the presser-rolls, whereby the carrier is made to travel in a vertical plane bisecting the presser-rolls at right angles to their axial lines, and so located relatively to the rolls that the carrier passes between the rolls, and from upper to lower side of the drums.

The swaging-dies are severally provided with the usual die-center B shaped to fit the interior of the shoe and raised from the plane anvil-surface B2, on which the shoe rests when presented to the presser-rolls. The raised portions, B3 are adapted to give to the outer surfaces of the heel of the shoe, or to maintain therein, a correct form during the swaging operation.

The swaging-dies are severally provided on their opposite sides with a recess B4 adapted to receive a supporting pivot DG projecting `interiorly one from each of a pair of oppo- IOO ended slots B4, in the opposite sides of the die-block, and each is provided on its inner end with a cylindrical head D9 adapted to enter the chambered recess B7 in the dieblock. I am thus able to pivotally support the dies on opposite sides which causes both sides of the die to continuously travel at the same rate of speed and properly present the shoes to the rolls and maintain them in proper position during the swaging operation. The dies, thus connected with the carrier, can be easily detached or replaced in case of breakage or wear.

It is only necessary to run the carrier around until the die to be removed is opposite the openin g F in the bed or frame, at which point the die can be easily raised from the carrier and withdrawn through the opening and another die substituted in its place in the carrier. When the carrier-supported dies are face upward, their backs rest upon the plane upper surface of the bed along which they slide, and by which they are confined within the carrier.

As the dies are sucessively carried from between the rolls on the upper side of the bed they are each inverted, as the carrier passes fromthe upper to the lower side of the drum, and the swaged shoe falls from the die by gravity into a suitable receptacle not shown.

The carrier-chains run parallel with each other and may be a pair of separate detached chains, or connected at intervals, as indicated by dotted lines G in Fig. 2, thus forming practically a single chain, the essential feature of my invention being a supporting connection between the carrier and two opposite sides of the die.

By pivotally connecting the die on opposite sides with the carrier, so that the axial line of such connection is parallel with the axes of the presser-rolls, as shown, the die is free to oscillate on such axial line in passing between the presser-rolls, whereby the strain upon the die and carrier is lessened.

Power is applied to the upper presser-roll through the pulley C2 fixed upon the roll-trunnion C3, and may be transmitted to the carrier supporting drums by means of the pulley 04 also fixed upon the trunnion C3, the pulley C5 fixed upon the sprocket-wheel shaft D4 and the connecting belt C6.

What I claim as new, and desire to secure by Letters Patent, is-

1. In ahorseshoe-swaging machine, the combination with a pair of presser-rolls,and drums severally rotary on parallel axes, of a pair of parallel carrier-chains supported and driven by the drums, and shoe-supporting dies supported by and between the carrier-chains, substantially as described.

2. In a horseshoe-swaging machine, the combination with a pair of presser-rolls, and an endless carrier, of a shoe-supporting die pivotally connected on opposite sides with the carrier, substantially as described.

3. In a horseshoe-swaging machine, the combination with a pair of presser-rolls, and an endless carrier, of a shoe-supporting die, and a detachable hook-and-eye connection between the die and carrier, substantially as described.

4. In a horseshce-swaging machine, the combination with a pair of presser-rolls, of an endless carrier, and a shoe-supporting die pivotally connected with the carrier on an axial line parallel with the axes of the presser-rolls substantially as described.

In testimony whereof I have hereunto set my hand this 11th day of July, 1893.

HENRY E. DARBY.
