Very satisfactory stocks have been designed by Gutenaecker, of Munich (Fig. 229). The four corner-posts (_a_, _a_, _b_, _b_) are eight inches square and eight feet long, of which three feet four inches are solidly implanted in the ground. They are united by side- and cross-bars (_c_, _c_, _d_). In front of the corner-posts (_a_, _a_) and in the middle line stands a head-post (_e_) of the same dimensions as the corner-posts, provided with a slot four inches wide and twenty inches long beginning three feet from the ground. In this slot is a pulley-wheel (_i_), and below it a windlass (_k_) for winding up the rope which is tied around the base of the animal’s horns. The corner-posts are provided with a slot (_n_) three inches wide and three inches deep, within which are placed two movable side-bars (_o_, _p_), which can be set at desired heights and fastened by iron pins. Between the front and rear corner-posts of the right-hand side is an eight-sided roller with a ratchet and click at one end, and having on one of the sides six iron hooks, to which a girth is attached. On the opposite side of the stocks, at the same height, is a stationary bar (_f_) with six hooks (_g_, _g_) on the outer side. The belly girth is six feet long, six inches wide, and terminates at both ends in several strong cords two feet four inches long with iron rings at their ends. Between the front corner-posts are a neck-yoke (_h_) and a breast-bar which slide in the slots (_m_) and may be fixed at desired heights by iron pins. On the rear face of each rear corner-post is an iron bracket (_s_) one foot and a half long, with a ring (_t_) six inches in diameter, through which passes a round pole padded in the middle and kept in place by two iron pins. Above each bracket is a hook (_u_) to which the end of the breeching attaches. [Illustration: FIG. 229. Gutenäcker’s stocks for oxen: _a_, front corner-posts; _b_, rear corner-posts; _c_, _d_, connecting bars; _e_, head-post; _f_, bar for holding belly girth; _g_, hooks for girth; _h_, neck-yoke; _i_, pulley-wheel; _k_, windlass with ratchet and click; _m_, slot for neck-yoke and breast-bar; _n_, slot for movable side-bars; _o_, _p_, side-bars; _r_, hook for fetlock strap; _s_, iron bracket; _t_, iron ring for rear cross pole; _u_, hooks for breeching.] Before an animal is brought into the stocks the neck-yoke is raised, the breast-bar lowered, and the girth left hanging from the hooks on the stationary bar. The ox is then led into the stocks and the rope which is tied around the base of the horns is carried over the pulley (_i_), fastened to the hook on the roller (_k_), and wound up till the head is tight against the head-post. The yoke and breast-bar are then placed in position and fastened, the breeching hung on the hooks (_u_), and the belly girth attached to the hooks on the roller, so that, if need be, it can be shortened till it bears the animal’s entire weight.
