STIRRUP. l

Specification of Letters Patent.

Application filed March 4, 1907. Serial No. 360,432.

.and useful Stirrup, of which the folllowing is a specification.

This invention relates to a safety stirrup oi that type l in which the foot plate, hinged to the inner leg of the stirrup'is detachably secured at its opposite end` to the other leg of the stirrup; and the object of the invention is to provide a simple and safe locking device for fastening the free ends of the foot plate in operative position, whereby it is secured from disengagement by any amount oi pressure the rider may place on the foot plate, or any rocking motion of the foot while the ,rider is in the saddle. v.ln connection with the locking device is a pivoted bow standing normally in a forwardly inclined position with the crown o the bow arch above the riders instep and so placed that if the rider is thrown or unseated, the toes oi his boots will act on the bow of each stirrup and cause them to unlock the toot plates and release the feet of the rider.

With this object in view the invention consists in the peculiar, combination and arrangement of .parts hereinafter described and definitely claimed.

In the accompanying drawings: Figure .l i's a perspective view oi the left stirrup as seen from the iront, the foot plate being disengaged and partly swung downward; Fig. 2 is a view of the outer side of the stirrup with the foot plate in position and locked. Fig. 3 is a detail perspective view of a portion of the stirrup showing the foot plate forked for engagement with a projection on one oi the side legs.

Similar numerals of reference indicate the same parts in the vfigures.

The stirrup which has the general form of those now in use, comprises a bow l, an outer leg 2 and an inner leg 3. A loop 4 is connected to the bow l for attachment to the usual stirrup strap. The lower end of the outer leg 2 is forked as shown at 5 above which fork is hinged a hook 6 on a pivot7. The lower end of the 4 inner leg is formed into a boss which serves as one part 8 of a hinged joint for the inner end 9 of the foot plate l0. A pin ll passes horizontally through the boss 8 and the inner end of the foot plate 9 to serve the pintle for the hinge joint. Springing from the hook 6 above its pivotal connection to the outer leg 2 is an inner how l2 the other end 13 of which is pivot-ally connected to the inner leg 3 by a pin la in line with the pivot 7 on the opposite leg. The height oi the bow is such that when the rider s foot is resting on the foot plate the usual motions of the foot may be made without touching or dangerously i moving the bow, but if an accident should occur and the rider be dismounted or thrown the toe of his boot would catch the bow and swing it on its pivots.

Patented July 9, 1907.

The foot plate l0, as before stated is pivoted to the inn er bow 3.

The outer end of the foot plate terminates in a T-shaped projection l5, the stein 1 6 of which passes, when the foot plate is in operative position, between the prongs of the fork 5 on the lower end of the outer leg 2. The lugs 17 on the cross piece 18 of the T head projection l5 pass around and brace the front and rcar sides oi the prongs ot the fork 5, respectively, thereby holding the foot plate rigidly in position and preventing it from rocking.

The bow l2 is now swung forward until the hook 6 passes beneath the projection l5, as clearly illustrated in Fig. 2, the bow assuming the forwardly inclined position there shown. In this position the weight of the bow being thrown forward of the vertical planevof the pivot 7 serves to maintain the hook 6 in locked position, and thus prevent accidental unlocking and release oi the foot plate when mounting or dismounting.

It will be understood that instead of a fork 5 on the end of the leg 2 straddling the projection of the foot plate, a pin 19 may be substituted for the fork and the ,inclined forwardly. Should the rider be thrown or dismounted his foot, rocking on the ioot plate as a ful- `crum would cause the toe of his boot to be raised to such a height as to strike the inner bow l2 and raise it to the substantially vertical position, shown in Fig. l. This would cause the hook 6 to swing forwardly on its pivot and pass from beneath the projection l5 oi the i'oot plate, which latter being relieved of any outside support would swing downwardly and release the rider 7s foot from the stirrup.

Having thus described the invention, what is claimed is The combination in a stirrup having inner and outer legs, of a foot plate pivoted to the in-ner leg and adapted to swing downward by gravity, the opposite end of the foot plate and the lower portion of the outer leg having interengagng members to prevent independent lateral play, a pivoted bow arranged within the legs, said bow having at one end a curved hook adapted to engage under the free end of the foot plate and hold the same-locked to the outer leg, the how when in locking position being in clined. forward, so that its weight tends to maintain the hook in locked position.
