WILLIAM P. SARRETT AND THORE A. BAKKE, OF WALLOWA, OREGON.

SAFETY-STIRRUP.

Specification of Letters Patent.

Patented NOV. 25,1913.

To all whom it may concern Be it known that we, WILLIAM P. SARRETT and THORE A. BAKKE, citizens of the United States, and residents of Wallowa, in the county of Wallowa and State of Oregon, have invented certain new and useful Improvements in Safety-Stirrups, of which the following is a specification.

This invention relates to improvements in safety stirrups.

The object of the invention is to provide a stirrup so constructed that a longitudinal and transverse motion permits one side of the stirrup to disengage and open thereby releasing the foot of the rider.

with this and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 represents a rear elevation of the stirrup in closed or operative position; Fig. 2 is a similar view of the stirrup in released or inoperative position; Fig. 3 is a side elevation of the stirrup in the position shown in Fig. 2; Fig. 4 is a side elevation taken from the inner side of the stirrup and with parts broken out; Fig. 5 is a similar view taken from the outside of the stirrup ;'Fig. 6 is a detail side elevation; and Fig. 7 is a similar view.

In the embodiment illustrated the invention is shown applied to a left hand stirrup but it may, of course, be used equally well on a right hand stirrup.

The stirrup shown comprises a foot plate or tread member A pivotally connected at one end as shown at H with a link I. This link I is pivoted at its upper end to a side member or standard B and positioned to swing in a plane at right angles to the plane in which the tread member A swings, said link being pivoted at F. The free end of the foot plate A is detachably engaged with the side member G as shown at G. A spacing member or cross bar D connects the upper ends of the side bar members B and G, and is preferably in the form of a sleeve having bolts E extending therethrough and through the ends of the side sections. This member 1) while it constitutes a spacing element for the side members also is designed to be engaged by a suitable strap, not shown, and which connects the stirrup to the saddle.

A catch J at the free end of the foot plate A engages a shoulder 0 on the member C when the plate is in operative or engaged position as shown clearly in Fig. 4:. This catch J has a hook d at its free end which engages the shoulder a and is provided at one side thereof with a recess which fits on a supporting hook f carried by the side member O. A pin G on the side member C engages a cam recess or track 6 in the cam catch J. This end of the tread plate A is held in closed position by a plate spring 6 secured at one end to the side member C and which bears on the upper hook shaped end d of the cam J and holds said hook yieldably in engagement with the shoulder 0. By this connection of the free end of the plate A with the side member 0 the same movement may be effected here that is produced at the hinge F at the other end of the plate until the cam J becomes disengaged at the points 0 and f from the member 0 when the stirrup opens and the tread plate A swings out into the position shown in Figs. 2 and 3.

The hinge F is preferably provided with a stop 2' which permits the link I to rotate only a distance sufficient to permit the cam J to disengage from the shoulders 0 and f and causes the stirrup to assume the position shown in Fig. 3. This stop 1' also prevents rotation of the link in the opposite direction.

A plate spring 72 mounted on a member I) engages a lug j on the link or cam member I and assists in holding the tread plate yieldably in operative position. The spring j is shown supported and held in position by a screw I and the groove n also by a slot in the inner portion of the side member B.

The side members B and C are preferably constructed of three strips fastened together by rivets as is shown in Fig. 7.

In the use of this improved stirrup should the rider fall and his foot remain in engagement with the stirrup the pull exerted thereby will cause the cam catch j to become disengaged fro-m the side member C against the tension of the springs b and Z0 and thereby release the tread plate A and cause it to swing in the position shown in Fig. 2 thus releasing the riders foot and preventing danger of his being dragged.

While we have described our invention with more or less minuteness as regards de berssand a tread plate pivotally connected atone end to one of said" side members to SWiIl in lanes at ri ht an les to each -other, and means: for detachably connecting the otherend of said plate With the other side member.

2. A. safetystirrup comprising side mem bersand, a tread plate pivotally connected at one end to one of said side members to swing in planes at right angles to each other,

.means for ,detachably connecting the other end of said plate With the other side memhem-said? means comprising a cam catch on ,sald itread plate, shoulders on said s1de mem- -ber- 1for engagement by said cam catch, and

a spring for holding said shoulders and catch in yieldable engagement.

3. A safety stirrupcomprising side mem-' bers, a spacer connecting the upper ends of said side members, a link pivotally connected at one end with the free end of one of said side members, a tread plate pivotally connected With said link to swing in a plane at right angles to said link, and cooperating means on the other side member and the free end of said tread plate for detachably connecting said plate and member.

4. A safety stirrup comprising side members, a tread plate pivotally connected with one of said side members a cam catch secured to the free end of sand tread plate and having a hook at one end and a recess at its other end, a shoulder on the other side member for engagement by the hook of said cam, another shoulder on said side member for engagement with the recess on said cam, said cam having a cam recess in its inner face, and a pin on said side member for engaging said cam recess.
