Y. Application February 13, 1948, Serial No. 8,207 3 Claims. (oi. 119 147) This invention relates to the cattle stanchion art and has for its primary aim to provide a stanchion which is practical and secure.

. The stanchion frame heretofore used has been latched in a closed position by means of a spring .themselves as this description progresses wherein reference is made to the accompanying drawings, in which Fig. 1 is a. view of the improved stanchion in front elevation;

Fig. 2 is an enlarged vertical fragmentarysectional view about on line 11-11 of Fig. 1;

Fig. 3 is a fragmentary view in longitudinal section showing the lock mounting;

Fig. 4 is 'a front elevation of a modified stanchion;

Fig. 5 is an enlarged detailed sectional view on line V-V of Fig. 4; and

Fig. 6 is an enlarged fragmentary view depicting the latch more clearly.

Referring more particularly to the accompanying drawings, the stanchion frame of Fig. l is made from channeled metal stock and comprises an upright frame member I having upper and lower transverse members 2 and 3, respectively, fixed thereto and forming therewith an opensided frame that is closed by an upright 4. This second upright frame member is movably secured at its lower end to the lower transversemember 3, as by a pivot forming bolt 5 that has selective engagement in one of a series of holes 6 therein to afford adjustment in size of the frame. The upper end of the second upright is bifurcated at 1 to straddle the upper transverse member 2 toslide thereon in guiding contact. This stanchion frame is suspended by a chain 8 from a stall structure 9 and has its lower end suitably anchored by a chain l0.

The movable stanchion or upright 4 has upstanding latch engaging portions H on opposite sides of the upper member 2 to be engaged by a pair of .latches l2 and I3. The latch part l5 where it is secured by suitable means such as a cotter pin IS. The latch I2 is likewise provided with the pintle or sha part l'l also journaled in the bracket l4 and its shaft part is provided with a crank portion 18 intermediate the two points of journal support in the opposite sides of the bracket 14, such bracket being in the form of a U-clamp adjustable along the upper transverse member 2 and suitably fixed by clamp bolts l9.

I3 is .journaled in abracket H by a pintle or shaft The suspension chain 8 has its lowermost link connected to this crank part I8 so that the weight of the stanchion frame will act through the crank part to urge and hold the latch l2 in. its operative position. The formation of the crank part provides a seat to receive the suspending member 8. Such lowermost link may also encircle the shaft part l5 for guiding support.

From the foregoing it will, be observed that the latch l3 may be manually lifted very readily, but that the latch I2 may only be lifted against the weight of the stanchion frame. Consequently, the cattle may shift and move the stanchion frame sideways without affecting the frame actuated latch I2.

In the embodiment shown in Figs. 4, 5 and '6, the stanchion frame has wooden uprights l' and 4' with the upper and lower transverse members 2' and 3' shaped from a metal strap and suitably secured to the fixed upright by a bolt 20. The movable upright 4' has its upper end guidingly arranged between the opposing sides of the upper member forming loop 2', the latter being provided with two series of openings 2| and 22 with the free latch l3 selectively engageable in an opening of the upper series 2| while the frame actuated latch I2 is selectively engageable in a hole of the lower series 22.

The improved stanchion is of practical design in that it permits the cattle to shift its position without jarring the latch inoperative. single latch type of stanchion it is possible for the cow, by moving her head about to extreme positions, to engage one of her horns with the latch in such a manner as to disengage the latch and therebyvpermit the stanchion to open and free the cow therefrom. This unauthorized opening of the stanchion is precluded in the present invention by the dual latch arrangement because both latches operate independently and therefore if the cow should lift one latch the other will still be operative to retain the stanchion in its closed position. Immediately upon the cow disengaging her horn from the latch the latter will drop down to its operative position so that the stanchion will again be secured by the dual latch arrangement.

In the w When it becomes necessary to unlatch the movable upright 4 (4) it is only necessary to lift on both latches. As the frame actuated latch is lifted, the crank part l8 will fulcrum upon the lower chain link and lift on the frame as indicated by the dot and dash lines 23 in Fig. 6.

The foregoing description has been given in detail for clearness and without thought of limitation since the inventive principles involved are capable of assuming other physical embodiments without departing from the scope and spirit of the appended claims.

What is claimed is:

1. A stanchion suspended by a flexible support and comprising separable upright frame members movably connected at their lower ends to enable placement of the stanchion frame about the neck of an animal, and a latch detachably securing the frame members together at their upper ends, said latch having a rigidly related pintle extending transversely of and journaled in spaced bearings provided in one of said frame members for pivotally mounting the latch to interlock with the other frame member, the portion of the pintle intermediate such bearings being radially displaced to form a crank part with a seat receiving the frame suspending flexible support to cause the weight of the suspended frame to crank the latch to its operative interlocked position.

.2. A stanchion suspended by a flexible support and comprising separable upright frame members movably connected at their lower ends to enable placement of the stanchion frame about the neck of an animal, a latch detachably securing the frame members together at their upper ends, said latch having a rigidly related pintle extending transversely' of and journaled in spaced bearings provided in one of said frame members for pivotally mounting the latch to interlock with the other frame member, the portion of the pintle intermediate such bearings being radially displaced to form a crank part with a seat receiving the frame suspending flexible support to cause the weight of the suspended frame to crank the latch to its operative interlocked position, said suspending support having an open link engaged in the seat, and a second latch having a mounting pintle journaled in said one frame member and extending through the open link in supporting contact therewith.

3. A stanchion suspended by a flexible support and comprising separable upright frame members movably connected at their lower ends to enable placement of the stanchion frame about the neck of an animal, and a latch detachably securing the frame members together at their upper ends, said latch having a rigidly related pintle extending transversely of and journaled in spaced bearings provided in one of said frame members for pivotally mounting the latch to interlock with the other frame member, the portion of the pintle intermediate such bearings being radially displaced to form a crank part with a seat receiving the frame suspending flexible support to cause the weight of the suspended frame to crank the latch to its operative interlocked position, said pintle with its crank being replaceable axially from the bearings, and means acting to retain the pintle against displacement.
