WOOD STIRRUP.

SPECIFICATION forming part of Letters Patent No. 267,961, dated November 21, 1882.

Application filed September 23, 1882. (No model.)

To all whom it may concern Be it known that we, JAMES WOOLWORTH and WILBER F. OowLEs, of St. Marys, in the county of Auglaize and State of Ohio, have invented a new and useful Improvement in Wood Stirrups, of which the following is a full, clear, and exact description.

Ourimprovements relate to the construction of wooden stirrups, in which the body of the stirrup is formed by bending a slat to the required shape and the ends connected by a roller or neck-block.

Heretofore in the manufacture of these stirrups, in order to use a roller having square ends, the slat has been formed with an offset at each end, so that when bent up the ends were of the required shape to receive asquareended roller; but in this form of stirrup, the slat being out at the ends diagonally of the grain of the wood, the stirrup was weakened at the point where the most strength was re quired. I

The object of our invention is to construct these stirrups so that they shall be equally as strong at the neck or bend as in any other part of the slat, and also to, provide for the easy bending of the slats, so that a good shape can be given to the body of the stirrup.

To these ends our invention consists of a slat bent into the desired shape and slitted in the direction of the grain of the wood, said slat being bent at its upper ends vertically where the roller or connecting cross-piece is connectedthereto, substantially as hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar lettersv of reference indicate corresponding parts in all the figures.

Figure l is an edge view of one of the slats from which a stirrup is to be formed after being cut and previous to bending. Fig. 2 represents a similar slat with the saw-kerfs differently arranged. Figs. 3 and 4. are side views of a complete stirrup. Fig. 5 is an end view of the same.

A in Figs. 3, 4', and 5 is a complete stirrup, the body portion of which is formed of the bent slat a, having its ends connected by the roller or neck-block 12.. against which the ends of the roller 11 take are bent outward, so that a roller having straight ends may be used, and the roller is attached in the usual manner by bolts 0, pass The ends of the slat a ing through it and the ends of the slat. In the manufacture of the stirrups the slats a are first cutout, of suitable width and thickness,

and with the ends tapering in the usual man- Fig. 4 shows a complete stirrup made from a slat similar to the one shown in Fig. 1. In Fig. 2 the cuts d extend only a short distance from the ends, or just far enough to allow of the bend to accommodate the roller. In order to form the main bend, the slat is made with saw-kerfs e, and these cuts we make of the V form shown, or widest at their outer ends, which allows of the ready bending of the slat to the form required; and it will be seen that the pieces between the saw-cuts being of dovetail form, or wider at the inner portion, it is impossible for the pieces to become loose and fall out, as is usually the case when thesawcuts are made of uniform width.

Fig. 3 shows a stirrup made from the slat shown in Fig. 2.

By this construction we are enabled to give the proper bend to the stirrup at the neck to receive a square-ended roller without weakening the stirrup. At the same time less material is required than in the ordinary stirrup, in which there is necessarily a waste in order to form the offset at the side.

It will be understood that we lay no claim in this application to the stirrup shown in Fig. 3 of the drawings.

Having thus described our invention, we claim as new and desire to secure by Letters Patentv The described wood stirrup A, consisting of the slat a, slitted in the direction of the grain of the wood, as at d, and of the roller or bar b, bolted to the slat, said slat being bent to stand vertically where the cross-bar or roller b is connected or bolted thereto, substantially as set forth.
