Fig. 1 is a perspective view of my invention.
Fig. 2 is a top plan view of the same.
Fig. 3 is a vertical central section.
A represents a bed-plate, which is provided at opposite ends with supporting
flanges or legs a. A square hole is formed in the centre of the bed-plate, through
which passes the square-portion b of the shank of the horse-shoe shaped. die-head B.
Below the square portion b of the shank, the shank is made round and is screw-
threaded as at b¹. A gear pinion C is interiorly-threaded to fit the threaded end
of the shank, and is screwed thereon, and bears between the underside of the bed-
plate, as at a¹, and the upper side of the sleeve C³ that is balanced on the horizontal
shaft D that has its bearings under the bed-plate.
A gear wheel E is fixed to the shaft, and meshes with the screw-pinion C, and to
the outer end of the shaft is secured a hand-wheel F. By this construction it will
be readily seen that the die-head may be raised or lowered with respect to the bed-
plate. In the upper face of the die-head is made a groove 6' which corresponds to
the contour of the die-head and is a suitable distance from the outer edge thereof.
A lever G which has a slot g cut in its rear end, is secured on the upper side of the
die-head, by a bolt H which passes through the slot and enters the die-head.
A projection g¹ extends from the lower face of the lever G and enters the groove b³.
The lever is adapted to sweep around the die-head, which remains stationary, by
reason of its square shank which enters the square hole that is made in the bed-
plate. A roller I is secured on the underside of the lever, by a bolt i, and bears
near the curved side of the die-head. A plate K is secured by screws k on the
front side of the lever, adjacent to the die-head, and has a downwardly-extending
portion in the inner lower corner of which is cut an angular notch, that is
adapted to receive the flange of the L-shaped bars from which the blanks for the
horse-shoes are bended.
I have shown one of these bars at X, in position in the machine. L represents
a stop that is secured to the bed-plate adjacent to the die-head.

page_text: This stop is composed of an eccentric
which is journalled on an upwardly-
projecting stud . A spring 12 has one end fixed in the bed-plate, and its free end
bears against the eccentric, and keeps it from slipping.
The operation of my invention is as follows:-
The bar to bend is inserted, after being heated, between the die-head and the
eccentric-stop, the flat side of the bar being under the die-head, and the flange of
the bar being between the eccentric-stop and the die-head, the roller bearing against
the outer edge of the bar, and its flange being in the notched guide-plate. The
hand-wheel is turned and the die-head lowered upon the flat side of the bar, and
the hand-lever is pulled around, which bends the bar into the shape of the die-head,
as will be readily understood. The die-head is then raised, and the blank removed,
and the operation proceeded with as before.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The combination of the bed-plate, the vertically movable die-head, the stop,
and the pivoted lever, having the bearing-roller and guide-plate, substantially as
described.
2. The combination of the bed-plate, the grooved die-head, the slotted lever that
is pivoted thereto, and that has a stud for entering the groove in the die-head, the
bearing-roller and the guiding-plate, substantially as described.
3. The combination of the bed-plate, the vertically-movable die-head, having
a screw-threaded shank, the internally-threaded wheel for raising and lowering the
die-head, and the pivoted lever for bending the blank, and the stop-substantially
as described.
4. The combination of the bed-plate, the die-head having the depending threaded
shank, the gear wheel screwed on the shank the horizontal shaft having the hand-
wheel, and a gear wheel that meshes with the gear wheel on the shank, the pivoted
lever having the bearing-roller and guiding-plate, and the stop that is secured on
the bed-plate, adjacent to the die-head, substantially as described.
5. The bed-plate, in combination with the die-head vertically-adjustable as
described, the stop for holding one end of the blank against the head, the lever
carrying the guide-plate to engage with the blank, and a roller mounted in the
lever and operating against the face of the die-head, for the purpose set forth.
6. The bed-plate, in combination with the die-head, the spring-pressed eccentric-
stop for holding the blank against the head, and a pivoted lever for bending the
blank, as set forth.
7. The bed-plate, in combination with the die-head, the stop for holding the
blank against the head, and the lever for bending the blank, said lever carrying
a roller, for working against the face of the die-head, as set forth.
8. The bed-plate, in combination with the die-head, the stop for holding the
blank, the pivoted lever, and a guide plate carried by the lever and formed with
a notch or groove to receive the flanged side of the blank, for the purpose set forth.
9. The bed-plate, in combination with the die-head, grooved on its upper face,
the pivoted lever for bending the blank, and pins or studs carried by the lever to
work in the grooves of the die-head, as set forth.
