I claim:
1. A horsehoe bending apparatus for forming horseshoes from strip bar stock and comprising:
(a) stationary frame means;
(b) form support means pivotally carried by the frame means, a forming plate carried on the support means and having a portion of the outer edge thereof in the shape of the inner periphery of the desired horseshoe, a pair of oppositely disposed guide plates carried by the support means on opposite sides of the forming plate for providing a channel around the outer edge of said forming plate for receiving bar stock therein;
(c) a bending stop member secured to the frame means and spaced from the forming plate, said stop member having a groove therein in a plane parallel to that of the forming plate;
(d) bar stock engaging means carried by the form support means for selective engagement with one end of the bar stock;
(e) means for rotating the engaging means with respect to the stationary frame means in a plane parallel to that of the forming plate;
whereby upon rotation of the engaging means, the bar stock segment is pulled through the bending stop member groove and is bent around said shaped portion of the forming plate outer edge to form a horseshoe.
2. The bending apparatus as set forth in claim 1 wherein the bar stock engaging means also comprises an elongated lever arm having a handle portion at the outer end thereof, the inner end of said lever arm being pivotally attached to the form support means, an elongated engagement tool pivotally carried by the lever arm and having a sharpened point for selective engagement with the strip bar stock, and locking means carried by the engaging means for selectively locking said engagement tool in engagement with said strip bar stock.
3. A bending apparatus as set forth in claim 1 wherein the forming plate has a first edge portion shaped substantially semicircular and the opposite edge portion shaped substantially in a half-elipse, the minor axis of the half-elipse coinciding with and common with the semi-circular portion cord.
4. The bending apparatus as set forth in claim 1 wherein the stationary frame comprises an elongated housing having means for attaching said housing to a stationary structure.
5. The bending apparatus as set forth in claim 4 wherein the form support means comprises an elongated rod rotatably and reciprocally disposed within said housing and having the outer end thereof extending out of said housing, the forming plate and guide plates being disposed on the outer end portion of the rod, the planes of said plates being perpendicular to the axis of the rod.
6. The bending apparatus as set forth in claim 5 wherein the outer most guide plate and forming plate are secured to the outer end of the rod for movement therewith and the inner guide plate is provided with a central bore therethrough for slidably receiving the rod therethrough.
7. The bending apparatus as set forth in claim 6 wherein an elongated helical compression spring is disposed around the outer periphery of the rod, one end of said spring being an engagement with the stationary frame, the opposite end thereof being attached to the inner end of the rod to yieldably force the rod in a direction interior of the housing, the outermost guide plate and attached forming plate being yieldably forced toward the inner guide plate.
8. The bending apparatus as set forth in claim 7 and including a vise operator means carried by the elongated housing and engageable with the elongated rod for selective longitudinal movement of said rod against the force of said helical spring.
9. The bending apparatus as set forth in claim 8 wherein the vise operator means comprises an aperature in said housing, an elongated foot pedal means pivotally attached to the housing adjacent said aperture, one end of said pedal means being engaged with the inner end of the elongated rod within the housing, the outer end thereof extending outwardly from said housing, whereby pressure exerted on the outer end of said pedal means moves the rod longitudinally against the force of the helical compression spring.
