STIRRUP FOR SADDLES.

SPECIFICATION forming part of Letters Patent No. 295,423, dated March 18, 1884.

Application filed May 23, 1983. (Model.)

To @Z5 whom it 11mg; concern:

Be it known that I, CHARLES C. PHIL- BRooK, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Stirrups for Saddles, of which the following is a specification.

This invention relates to metallic stirru'ps. Stirrups are of two general sorts-those with guards or toe-pieces, which prevent the insertion ofthe foot too far, and "open stirrups. All stirrup's, whether open or with toeguards, have two parts in common-the sole-plate77 and the bailg and also athird part for suspending the stirrup, soleeplate down, which in metallic stirrups is usually an 'eye perforated in the top bend of the bail, or attached to it. Hooded or toe-guard stirrups are preferred by .some people, because, in case the rider is thrown, the foot generally disengages more readily than from an open stirrup; and many people dislike the appearance of a stirrup with its sole-plate carried under the hollow of the foot, although the comfort of this position of the foot in the stirrup is gen'- erally acknowledged.

Hithertono metallic stirrup having toeguards and made in a single piece without rivets has come upon the market, and no such stirrup with toe-guards has been made of cast metal.

Hy invention relates to a stirrup having toe-guards, sole-plate, suspension-bail, and strap-eye, so shaped and modeled that it may be cast in a single piece in an ordinary twopart mold. Y

In the drawings, Figure 1 is a perspective from the rear end, and Fig. 2 is a perspective from the toe end.

Like lettersv indicate like parts in both figures.

A is the sole-plate, B is the strap-eye, B B2 are the branches of the suspension-bail, and G C are the toe-guards. lhe inner surfaces of the sole-plate A, branches B' B2, and toeguards O C all converge toward an imaginary point at or near the curve of the toe-guards, which bend over the toe of the riders foot, cr are transverse or inclined to it, so as to make draft-planes for the molder.

The

front surfaces as draft-planes for drawing in,

the opposite direction.

To start the molding operation a smooth plug or core is placed in the interior of the pattern, fitting the interior draft-planes, and having an external surface, which unites them by flowing curves, which are draft-planes for the same direction as the draft-planes of the exterior. lf the interior ofthe eye B is to be larger in front, its interior draitplanes may be toward the front. In this case the eye B would not be plugged in starting the molding. If the draft-planes of the interior of the eye B are t0 draw to the rear, the eye B should be plugged at the beginning. It is probably indifferent in which way of the two above suggested the draft-planes of the interior of the eye point. The pattern being placed on the plug or core described, the cope-frame is put round it and the sand sprinkled and rammed, as usual. It is then lifted off, the plug of the cavity of the stirrup pulled, and, if any, the

, plug of the eye B also, the parting sand scattered, and the other partof the mold placed, filled, rammed, and the like, the operation being thus, after the formation of the cope, continued in the usual way of molding in two-part molds.

It will be seen that the novelty of this stirrup is in the formation of its interior and back surfaces as drawing-planes from one direction, and of its exterior and front surfaces as drawing-planes from the opposite direction, whereby it is adapted for casting in a two-part mold, and also has imparted t0 it a graceful and peculiar appearance, as well as a character of solidity in the suspensionbail and foot-plate, and of lightness in the toeguards, specially desirable in this form of IOC 1o as described, in which all the interior and stirrup, and giving a better hang, when the l back surfacesare formed and fashioned as rider is not mounted, than is usual in stirrups draft-planes from one direction, and all the with curved toes, because it is less toe-heavy exterior and front surfaces are formed and than is usual. l fashioned as draft-planes from the opposite I claim as my invention and desire to secure direction, for the purpose set forth. by Letters Patentl An improved stirrup having suspension- CHARLES C' PHILBROOK' bail B B2, sole-plate A, strap-eye B, and toe- "Vtnesses: guards C C', of a single casting, substantially FRANK G.
