STANCHION'.

SPECIFICATION forming part of Letters Patent No. 496,390, dated May 2, 1893.

Application filed September 29, 1892. Serial No. 447,214. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM S. ANGELL and CHESTER A. WINN, citizens of the United States, residing at Charles City, in the county of Floyd and State of Iowa, have invented certain new and useful Improvements in Self- Olosing Stanchions; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to stanchions for fastening cattle in their stalls, and its object is to provide a simple, strong and efficient device for the purpose named. The stanchion comprises two bars, one fixed and the other substantially parallel therewith and rotatable on its axis. Means are provided which hold the rotatable bar normally in a closed position, but yield automatically to permit the bar to rotate when the animal inserts its head. The bar can be rotated by hand when the animal is to be released, and devices may be provided for opening all the stanchions simultaneously.

In the drawings, Figure 1 is an elevation from the manger side of two stanchions embodying our invention, and shown in an open position. Fig. 2 is a top plan view, and Fig. 3 is a detail view. Fig. 4 is a perspective view showing the stanchion closed. Fig. 5 is a detail view of the upper end of a stanchion, showing it open.

To a suitable sill A and top plate B are fastened upright posts O O, the former constituting the fixed bars of the stanchions. The other bars D are attached to the sill and plate, or to bars fastened thereto, by suitable pivots, hinges or the like, so as to be capable of swinging on a vertical axis, like a door.

When turned into the position shown in Fig;

4 and in dotted lines in Fig. 1, the stanchion is closed,the space between the bars 0 and D being then insufficient to permit the animal to withdraw its head. But when the bar D is turned into the position shown in full lines, in Figs. 1 and 5 the space between the some device which permits it to yield inwardly toward the manger when the animal pushes its head between the bars. This device is preferably a spring E, attached at one end to the frame, and at the other end to the turning bar. Any suitable substitute for the spring may be employed, such as a weight. This yielding device permits the stanchion to open inwardly only and prevents the animal from backing out after it has pushed its head through the bars, and the turning bar has swung back against the animals neck.

To release the animal, the bar may be turned by hand. If two or more are to be released at the same time, the turning bars may be connected so as to be moved simultaneously. This may be accomplished in any suitable manner, as for instance, by a rod F sliding in eyes f and having studs f to engage with arms d projecting from the turning bars. A lever G may be arranged to operate the rod. When moved to the position shown in full lines in Figs. 1 and 5, the studs f carry the arms 01 to the left, and thus open the stanchions. Upon releasing the red, the springs automatically close the stanchions. Notches f in the rod permit any stanchion to be opened by hand, when the rod is so wide as to overlap the'ends of the bars D.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. Astanchion comprising two bars located a suitable distance apart, to receive the neck of the animal one being pivoted on a vertical axis at or near the edge farther from the other bar, and a yielding device for holding the pivoted bar closed, substantially as described.

2. In a stanchion the combination with a stationary bar, of a bar turning ona vertical axis at or near the edge farther from the stationary bar, and a spring having one end attached to the turning bar to hold it yieldingly closed, substantially as described.

3. The combination with two or more stanchions, each comprising a stationary bar, and

a bar rotatable on a vertical axis, of means I00 for simultaneously turning all said rotatable In testimony whereof We affix our signatures bars, substantially as described. in presence of two witnesses.

4. The combination with a stanchion comprising a fixed bar, and a bar turning on a 5 vertical axis, of means for yieldingly closing said tnrningbar, an arm projecting from said Witnesses:

bar, and a sliding rod having a stud to engage ROBERT EGGERT, with said arm, substantially as described. HIRAM A. SCHNEIDER.
