An arm 35, which is secured to the rear ear 24 of the lower' yoke extends upward to a point adjacent to the pivoted end ofthe spreader-bar, to which bar the arm is connected by a link 36. i

In some instances, it is not necessary'that i the hinged rail should be opened to its full extent this being the case When'small cattle are handled and in such instances, the pivot' bolt of the spreader-bar may be removed from the position shown and inserted in an `indicated by the dotted lines.

aperture 37, the hinged rail 17 being connected to the spreader bar through this aperture, it will be seen that in its opening movement the distance between the rails will be proportionately lessened. When this adjustment is effected, it follows that the link 36 must also be connected to the spreaderbar in a relatively proportioned distance, the said spreader-bar being provided with anaperture 38 for this purpose, and while I have shown only a single set of apertures for this adjustment, it is apparent that a series of such apertures may be provided.

Both the 4upper and lower strap-members, in which `the stanchion is trunnioned are provided with a series of apertures, into any pair of which may be fitted the retaining bolts 39. By this arrangement," as best shown in Fig. 3, the trunnions of the stanchion may be adjusted back and forth from the center-line of` their supporting-sills,

whereby said stanchion is brought in the correct position relative to the rear of the' stall in order to accommodate the device to the varying lengths of cattle, it being understood for sanitary reasons, it is desirable that the excrement from all the animals should'be deposited within .the line of a fixed trough to the rear of the stall.

'lhe several parts of the stanchion being in the position shown in Fig. 1, the animal can readily insert its head within the space between the upper yoke ando trip-bar. In owering its head, the animal causes t-he bar 32 to be disengaged from the pin 33, whereby the compression coil spring 28a is released, and its power will thus swing the hinged' rail inward to the locked position as This movement of the hingedr ra'il also causes the tripbar to swing down, as shown in the dotted position due to the link-connection between said trip-bar and yarm35. 4The upper end of the hinged rail in moving over to the locked position engages the nose of a dog 40, which dog drops over the rail and locks the same in this position, the dog being pivloted between the side-walls of the upper yoke as shown. Simultaneously with the engagement of the rail and dog, the inner edge of said rail strikes the tappet-bar'l3 and thereby disengages the bolt 8 from yits looked posit-ion with relation to the trunnion 3, thus rendering the stanehion free to swing about its axis, it being understood that the upper and lower trunnions are axially alined.

While I have shown and described the bolt 8 as being spring controlled, in some instances, the spring may be dispensed with, and when the operator pushes the hinged rail to its unlocked or open position, he may at the same time'manually operate the bolt so as to effect a locking operation between the stanchion and its upper trunnion, it being also understood that the operator is required to lift the dog 40 prior to unlocking the stanchion, said dog being held in engaging position relative to the hinged rail by a stop-pin 41, shown.l It will also be observed that the locking movement of the spring-controlled hinged rail is limited by means of the stop-nut 29, which nut is preferably adjustable and arranged to be engaged by the tongue 27'i11 opposition to the tensionof the released compression spring 28, which spring is preferably lhoused by the upper wall of the lower yoke to insure the same against accumulations of foreign matter.

I claim:

,1. A stanchion comprising upper and lower ykes, a fixed rail secured to the okes, axially alined trunnions for the yores, a spring-controlled rail in hingeconnection with said lower yoke, and a locking-bolt carried bythe upper yoke arranged to engage its trunnion, means 1n connection with the locking-bolt arranged to be actuated by the hinged rail, whereby said bolt is disengaged from the trunnion, and a spreader-bar interposed between the fixed and hinged rails in opposition to the spring-pressure exerted upon said hinged rail, the spreader-bar being arranged to be actuated in one direction by the animal.

2. A stanchion comprising upper andlower yokes, a fixed rail secured to the yokes, axially alined trunnions for the yoke's, a spring-controlled rail in hinge-connection with the lower yoke, a 'pivoted spreader-bar interposed between the fixedy and hinged rails, an arm extending from the lower yoke, a link connecting the arm and spreader-bar, a locking-dog for the hinged bar carried by the upper yoke, a spring-controlled bolt carried' by saidupper yoke, thebolt being adapted to engage e recess in the upper` yoke l'iunxi'ion, and means in connection with the holt arranged in the path of travel of the :ifoi'eeuid hinged rail, whereby the latter effeats a releasing movement of thebolt relati\ 'e to its seat in the recess of the trunnion. hiltestimony that I claim the foregoing` I i have hereunto set mj' hand at Milwaukee in the county of Milwaukee and State of Tisconsin in the presence of two witnesses.
