PATENT CARL KNOPF, OF AKEN, GERMANY.

STIRRU P.

SPECIFICATION forming part of Letters Patent No. 635,556, dated October 24, 1899.

Application filed May 19, 1399- Serial No. 717,462. (No model.)

To all whom it may concern:

Be it known that I, CARL KNOPF, mechanical engineer, a subject of the Emperor of Ger= many, residing at Aken-on-Elbe, Burgthor 1, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Stirrups, of which the following is a full, clear, and exact description.

The invention relates to stirrups for ridingsaddles; and it consists in the construction and novel combination of the parts of the stirrup, as will be hereinafter fully described and claimed.

In the drawings hereto annexed and forming part of this specification, Figure 1 is a rear elevation of a stirrup embodying theimprovements of my invention. Fig. 2 is a vertical sectional detail view, the upper and lower portions only of the stirrup being shown in section. Fig. 3 is a side elevation, partly in section, showing the connecting-piece d in dotted lines when in position within the strengthened middle portion 0 of the stirrup and in full lines in sectional view when disconnected from its seat in the strengthened middle portion 0 of the stirrup. Fig. 4 is a sectional detail view taken on the line A B in Fig. 1.

Referring by letter to the accompanying drawings, 1) b designate the detachable stirrup-body, the sides of which curve outwardly in opposite directions and are connected at their lower ends by the usual rest for the riders foot. The upper ends of the curved sides I) b of the stirrup are suitably secured in the end of the strengthening block or piece 0, which is provided with a downwardly-tapered centrally-located slot 6', extending en- A transversely-disposed circular opening 6 extends entirely through the strengthening block or piece 0 and intersects the downwardly tapered slot 6'. A locking and a releasing pin f, provided with ahead f at one end and a flat reduced middle portion e, is curved at its opposite end in the direction of the height of the stirrup and is slitted or split to receive a loop g on the inner face of the transversely-curved half-hoop a, said loop q being retained in the split end of the pin f by a transverse pin p,

driven into a'lined holes provided for its reception. The ends of the half-hoop a are connected to the stirrup sides by suitable joints, as atjj. Two fiat springs g g, Fig. 1, under all ordinary circumstances hold the movable flat half-hoop a away from the stirrup, so that the cylindrical part of the pin f next to the head f occupies the tapered space in the block 0.

d is a wedge-shaped connecting-piece which is attached to the stirrup-leather by a loop fastening. The wedge-shaped connectingpiece (I is provided'with a circular pin-seat 6 made therethrough a short distance above the lower end thereof, and a slit or opening 61 leads from the circular pin-seat 6 down-- wardly entirely through the lower portion of the connecting-piece d.

When the connecting-piece cl is in its tapered seat in the strengthening-piece c of the stirrup, the half-hoop a, pressed outwardly by the spring g and the cylindrical portion of the pin f, occupies the opening e in said connecting-piece d. \Vhen the riders foot occupies the position shown in dotted lines in Fig. 3that is, in the upturned position-showing that he has been displaced from the saddle, and when the fall occurs, the upturned foot of the rider presses the half-hoop a back and the fiat portion 6 of the pin fis forced back and comes opposite the slit or opening 61 in the connecting-piece d and permits the flat portion 6 of the pin f to pass through the slit or opening 61 thereby releasing the stirrup from the connecting-piece cl, attached to the stirrup-leather, and prevents the rider from being dragged along the ground, as he would otherwise necessarily be. foot of the rider should pass through the stirrup the half-hoop would be automatically pressed back and the stirrup would be released from the connecting-piece d.

Having thus fully described myinvention, what I claim, and desire to secure by Letters Patent, is p In a safety-stirrup, the combination with a stirrup-frame provided with a centrally-disposed strengthening-piece c having the vertical tapered slot 6', and the circular inter- Even if the entire secting pin-seat (2*, of the movable pin f, f outlet-slit d communicating with said openhaving fiat portion e intermediate its ends, ing 6 substantially as specified. 10 the slitted end portion, the flat half-hoop a In Witness whereof I subscribe my signaconnected with the stirrup sides by hingeture in presence of two Witnesses.
