Stir′rup.
1. (Manege.) A loop or ring suspended from the saddle for the foot of the rider. Fig. 5821 shows several kinds of stirrups. a. is formed of a block of wood, through which the stirrupleather is rove. a′ is the block detached. b has a pair of branches, which, if a rider be thrown and the foot catch in the stirrup; pull apart and release the foot b′ is a spring which holds the parts in normal position, except when the strain occurs in case of accident. c is also a safety-stirrup, having a pivoted foot-rest which throws the foot of a dismounted rider out of the stirrup. d has a roller at the top and joints at the sides, to release the foot. e has a guard to keep the foot from penetrating so far that it would be jammed in case of accident. f is the Eagle stirrup. It has a bent wooden frame, with arms united at top by a ferrule and stirrup-strap. g shows the frame detached. h is the hood. The ancients mounted their horses in various ways:— By vaulting. By short ladders. By teaching their horses to kneel. By horse-blocks. By grooms, who lifted them on. By the hands or knees of their servants. By a step or projecting-bar on their spears. No traces of the stirrup are found in the old Greek and Latin writings, coins, or statues. The celebrated equestrian statues of Trajan and Antoninus are destitute of stirrups, the legs of the riders hanging down without any support whatever. Xenophon does not mention them in his work on horsemanship and the art of riding. See saddle.

2. (Machinery.) A band or strap which is bent around one object and is secured to another by its tangs or branches. 3. The iron loop or clevis by which the mill-saw is suspended from the muley-head, or in the sash. A sawbuckle. The example (Fig. 5823) shows two forms. The saw-blade may be held by a cotter or key which passes through a hole in the saw and above the bar from which it is suspended; or it may have cheekpieces riveted to it, which afford hold for clamping devices.
