STIRRUP.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application led May 26, 1908. Serial No. 435,062.

To all whom @t may concern.'

Be it known that l', ROBERT E. H. Jol-1N- soN, a subject of the Emperor of Germany, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new and useful improvements in Stirrups, of which the following is a Heat-ion.

This invention relates to stirrups and embraces certain safety means by which certain dangerous features possessed by the ordinary stirrup are overcome whereby the foot of the rider is not liable to be caught or entangled in the new device and in case he falls or is thrown from the horse hisfoot is released. These and other features and Adetails of the invention will be more fully explained in the following specification, set fort-h in the claims and shown in the drawings, where:

Figure 1 is a sectional view of the stirrup through its center while in its normal condition. Fig. 2 is a front view of t-he device in its operative condition. Fig, 3 is a bottom plan view. Fig. Llis a top plan View.

The device comprises a base piece 5 of thin metal and having on its upper surface a grooved sheathing 6 of rubber or other substance to roughen same and prevent the foot of the person using the stirrup from slipping therefrom. Vertical `lugs 7 are also provided to prevent the lateral movement of the foot and the displacement of same.

At the front of the plate 5 rises an up right 8 which curves backward and at its end carries a block 9 with a vertical slot 10. Depending from the block 9 and on a line with one of the walls of the slot is a plate 11 whose object will be later explained, and to the upright are secured side braces 12 and 13 which are secured to each other giving the stirrup a solid and substantial character.

To the base plate 5 and the upper face of the block 9 are pivoted guard rods 14 which when not in use are sprung forward into the position shown in Fig. 1 but when the stirrup is in use and a pressure is exerted on the plate 5 the rods 14 are swung around on their pivots 15 to the positions shown in the other views or around towards the rear of the plate and at right angles to the upright S.

The guard rods 14 are thrown to their forward position and retained there by the springs 16 operating upon extensions 17 near the lower pivots as shown in Fig. 3, which also shows the guard rods in their forward position in dotted lines.

speci-- Adapted to move vertically in the slot 10 is a sliding plate 18 to the upper end of which is secured the stirrup strap 19 and it is retained within the slot 10 by a pin 20' which passes through the slot 21 and at the same time limits its vertical movements. This plate 18 has at each side the cam faces 22 and depressions 23 and it is in the latter that the guard rods 14 are located when in their forward or inoperative position. The plate is held in its lower position by the spring 24 which is secured to the upper end of the upright S and whose ends pass through ears 25 at the lower sides of the plate.

The operation of the safety device connected with the stirrup is as follows: As long as there is no weight on the plate 5 and strain on the strap 19 the rods 14 are sprung forward towards the front of the device thus clearing the sides but when a pressure 1s put upon the base plate the plate 18 is drawn upward through the slot 10 and the inclined sides 22 force the rods 111 around on their pivots until they occupy positions at right angles to the upright 8 and prevent the lateral displacement of the foot which causes the pressure. If through any accident the plate 5 is relieved of its pressure the plate 18 is returned to its normal position and the rods 14 allowed to return to their place towards the front of the stirrup as shown in Fig. 1 and in dotted lines in Fig. 3.

It is obvious that I do not confine myself to the exact construction of the parts as shown in the drawings as they may be modified or otherwise arranged without departin the plate ing from the essential features.

What I claim as new and desire to secure by Letters Patent is:

1. A stirrup comprising a base plate, suspension means for said plate, a sliding plate connected to the suspension means pivoted side guards at the frontof the stirrup, and means carried by the sliding plate forthrowing the side guards to the sides of the stirrup when pressure is put on the same.

2. A stirrup having a sliding plate a strap connected to the plate, said plate having cam faces, and guide bars normally positioned at the front of the stirrup and arranged for engagement with the cam faces when pressure is put upon the stirrup, whereby said bars are thrown to the sides of saidstirrup.

3, ln a stirrup, the combination with suspending means, of a base plate, pivoted guards at the sides of the stirrup, and a plate operated by the suspending means to hold the guards at the sides of the device.

el. In a stirrup, the combination with a sliding plate by which the stirrup is hung, ol" an upright from the base plate carrying the sliding plate, side guards normally positioned at the front of the stirrup, and means on the sliding plate to throw the side guards to the sides of the stirrup when pressure is put on same.

5. In. a stirrup, the Combination with a base piece, of an upright, a slotted block at the end of the u'pright, a sliding plate in the slot vin the block and hanging from the suspending strap, a spring to retain the block at its lowermost position, Cam faces on the plate and pivoted side guards at the front of the stirrup and adapted to be thrown to the sides when pressure is put on the stirrup.

In testimony whereof I affix my signature in presence of two Witnesses.
