Specification of Letters Patent.

Patented Dec. 11, 1917.

Application filed October 15, 1917'. Serial No. 196,721.

To all whom it may concern.

Be it known that I, ERNEST TILLER, a sub ject of the King of Great Britain and Ireland, and resident of London, England, have invented certain new and useful Improvements in and Relating to Presses for the Manufacture of Horse and Like Shoes, of which the following is a specification.

This invention which relates to the manufacture of horse and the like shoes is characterized in that the bar forming the shoe is maintained at a white heat during shaping and tooling, the inner curve of said shoe beingkept heated while striking the nail holes and heels during finishing off, so that a shoe is turned out perfectly flat and symmetrical, obviating constant re-heating and consequently a lot of smiths work.

The invention is illustrated by the accompanying sheets of drawings in which Figure l is a plan view of a press embodying the essential feature of the said invention.

Fig. 2 is an elevation thereof, partly in section.

Fig. 3 is a plan view of a modified arrangement of press.

Fig. 4 is a similar view but showing the top member of the press raised.

Fig. 5 is a sectional view on line :20, of Fig. 3.

Fig. 6 is a front view of Fig. 4.

Like letters of reference indicate correspending parts in the several figures.

in carrying out the invention and referring first to Figs. 1 and 2, which show a press constructed in such a manner that the upper member of said press not only holds the shoe to the upstanding portion or die block of the lower member of said press but also serves to shape the shoe to the die blocklower member so as to give it its finished form.

A white-hot bar 0:, indicated in dot-and dash lines Fig. 1, from which the shoe is to be formed, is clamped by one end on to the upstanding portion 6 of the lower press member a by means of a clamping device (Z and the lever e which is pivotally mounted on a rod f extending upward from the lower press member a is pulled around 011 its pivot to the position shown in Fig. 1, bending the bar, by the engagement therewith of the roller 9 which is carried by the lever 6, around the wall it of the upstanding fixed die element 5. The nail holes in the shoe may be drilled before being, but otherwise are, struck through the striking holes i in the lever 6, holes 7' to correspond with those formed in the shoe being provided in the upstanding portion to allow of the penetration of the striking tool through the shoe.

To keep the bar a at a white heat during the pressing and striking the lower press member a is heated from below by means of one or more gas jets 76, Figs. 1 and 2, or blasts of air and gas, in such manner that the walls it of the upstanding portion F) become so heated as to keep the shoe, especially (and this is an essential feature of the invention) the inner curved surface of said shoe, at a white heat, and this is effected by chamber-111g the body of the lower press member and providing the same with a central hole at through which extends vertically the pivot rod f of the lever e for the passage of the heat.

Referring now to Figs. 3 to 6, which show a modified arrangement of press used with the foregoing arrangement for finishing off and tooling the shoe.

The white-hot shoe is placed around the upstanding portion or former die block Z) of the lower press member, said upstanding portion being shaped to the true inner curvature of the finished shoe by the arrangement previously described with reference to Figs. 1 and 2 and in lieu of or in addition to the upper press member of the previous arrangement, viz:-the pivoted lever e and its roller 9, use is made of a presser plate 6 hinged at e to the lower press member and recessed on its underside at a Fig. 6, to correspond to the true outer shape of the shoe.

This presser plate 6 is now brought down and pressure applied to the handle a of the presser plate a which now constitutes the upper press member, and to maintain or keep the shoe at white heat during pressure the lower member 0 of the press is heated from below by one or more gas jets 1; in such a manner that the walls k of the upstanding portion of said lower member 0' become so heated as to keep the shoe, espe cially the inner curved surface thereof, at a white heat. This, as shown in Figs. 4 and 5, is effected by chambering at b the upstanding portion b, which portion 6 is now closed at the top, that is to say, the central hole m in the previous example is dispensed with, and providing a series of holes or passages b radiating from the center and through said upstanding portion to the walls 7:, thereof and by an undercut passage 12 running around the walls h of said upstanding portion so that the heat or jets of flame may play upon the inner curved surface of the shoe, the heat or flame passing out by way of a hole 12 in which the undercut b terminates and a corresponding hole 6 in the upper member or presser plate e.

The presser plate '6 and the upstanding portion b areprovided with holes 2" and y" shaped to aline with one another when said presser plate is brought down, so that the nail holes and heels can be struck in the shoe, all correctly. positioned before said shoe is removed, the walls of both presser plate and upstanding portion being slightly beveled to allow of the easy removal of said shoe.

To assist in maintaining the heat while bending and striking, the lever e, i. 6., the upper press member of the first described arrangement, may carry any suitable arrangement of nozzles or jets connected up with a gas supply in order that a flame or flames may play upon the bar while being tooled, and, if desired, the radially disposed holes or passages of the second described arrangement may also be employed in conjunction with the first described arrangement.

The arrangement of heating and the holes and passages in the upstanding portion of the lower press member may be varied without departing from the spirit of the invention, viz :maintaining the shoe at white heat and the heating of the inner curve thereof while striking and finishing 011'.

Having now described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. An apparatus for forming horse shoes including a chambered press member, means for supplying heat to said chamber, a fixed die element on the press and having a central chamber in open communication with the chamber of the press member whereby the heat therefrom will maintain the inner side of the die in a heated condition, and a movable die member cooperating with said fixed die.

2. A press for formin or finishing oii horse and like shoes consisting of the combination of a former die block upon which the heated metal is placed, means whereby said former die block is adapted to be heated to maintain the temperature of the metal, and a movable die member to compress the metal on to the former die block and hold it and mold it on to the former die block.

3. A press for the manufacture of horse and like shoes, consisting of a former die block shaped to the true inner curvature of the finished shoe, means for heating from below the former die block around which a heated metal bar is adapted to take, said former die block forming the lower member of a press, an upper presser member adapted to draw the heated metal to its outer inished curvature, said presser members having striking holes.

4. A press for the manufacture of horse and like shoes, comprising in combination a chambered lower press member, a former die block thereon shaped to the true inner curvature of a shoe, a central opening extending from said chamber and through said former die block, jets or nozzles for conveying a source of heat to said chamber and central opening, a rod extending vertically through said central opening, a lever pivotally mounted on said rod, a roller carried by said lever, and a clamp for clamping the heated metal on to the former die block.

In testimony whereof I have ailixed my signature this 27th day of September, 1917.

ERNEST TILLER.
