Appiication July25, 1936, Serial No. 92,660

3 Claims.

The device forming the subject matter of, this application is a stanchion structure for a stall, and one object of the invention is to provide novel means for holding one of stanchion members against opening movement when the other stanchion members are opened. Another objectof the invention is to improve the mechanism by which the so-called sure stops are operated'and controlled. I r

It is within the province of the disclosure'to improve generally and to enhance the utility of devices of that type'towhich the invention appertains. Y

With the above and other objects in view,

" which will appear as the description proceeds, the

invention resides in the combination and arrangement of parts and in the details of constructicn hereinafter described and claimed, it being understood that chang es in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention. a

In the accompanying drawings: Fig. 1 is a perspective view showing a device constructedin accordance with the invention;-

Fig.'2 is a top plan wherein parts are omitted; Fig. 3 is an elevation showing the stanchions opened, parts being broken away; 7 a Fig. 4 is an elevation showing the movablestanchion members held closed by the locking pin;

Fig. 5 is a'detail enlarged from Fig. 4, parts being broken away; a a

Fig. 6 is a longitudinal section on the line 6 6 of Fig. 5; I V

Fig. '7 is a transverse section on the line 1-1 of Fig. 5;

Fig. 8 is a section on the line 8-8 of Fig. 3. In the drawings, there are shown many parts which are well known in the art, and the descrip: tion of those parts may be shortened accordingly. The numeral 5 marks a base carrying stall posts 2. Partitions 3 are connected to the base I and to the stall posts 2. Parallel track rails 4, preferably outwardly and oppositely facing channels, are secured at 5 to the upper ends of the stall posts 2. Anchor blocks 6 are held by securing elements 1 between the track rails 4.

Relatively fixed stanchion members 8 are pro vided. Any suitable means 9 may be supplied for connecting the upper ends of the stanchion members 8 for swiveled movement to the blocks 6.

(CL- u h-148) lower ends of the stanchion members 8 and i loosely to the base i. The stanchion members I0 haveextensicns it at their upper ends, these extensions working between the parallel track rails 4.

Parallel slide rods I5 operate above the track rails 4. The rods l5 may be actuated in any suitable way, for instance by means of a lever l6, fulcruined on the track rails 4, a link ll being pivotally connected at one end to the lever l6, and 10 being pivotally connected at its opposite end to the slide rods l5. U-shaped connectors ifi'are pivoted. at 9 to the slide rods l5 and the bends of the connectors I8 receive the extensions [4 of the movable stanchion members l0.

As one of the novel features of the present invention, it is to be observed that brackets 29 are held by the securing elements I on one of the rails 4. The brackets have oppositely prolonged extensions 2! engaging the horizontal 53 flangesof the corresponding track rail l, to hold the brackets in the horizontal position of Fig. 5. Each bracket 20 terminates in a hollow head 22. The hollow head 22 has a key hole slot including a circular portion 23 and an extension 24. There are openings 25 in the body portions of the track rails 4, The openings 25 are arranged in substantial. alignment with the circular portion 23 of the keyhole slot in the head 22 of the bracket 263.

VA locking pin 26 is mounted for longitudinal 30 sliding movement in the openings 25 of the track rails 4, and in the circular portion 23 of the key hole slot in the head 22 of the bracket 28. At one end, the locking pin 26 has an enlargement 21. Intermediate its ends the locking pin 26 is provided with a laterally projecting bit 28. The locking pin 26 is supplied at one end with an offset handle 29. The handle 29 projects in a direction opposite to the bit 28. The enlargement 21 on the locking pin can pass through the openings 25 of the rails 4, but is large enough so that it cannot pass through the circular portion 23 of the key hole slot in the hollow head 22.

In order to prevent the cattle from inserting their heads into the wrong places, upwardly extended sure stops 32 are provided, these sure stops being disposed between the stanchion members 8 and the stall posts 2. The lower ends of the sure steps 32 are pivotally connected at 33 to brackets on the stall posts 2. In their upper ends, the sure stops 32 have elongated slots 34 (Fig. 3). The

upper ends of the sure stops 32 operate between the track rails 4. In the slots 34 of the sure stops 32 work connections 35 joining the ends of links 38 pivoted at 31 to brackets 38 secured to the slide rods l5.

Collars 39 are slidably mounted on the sure stops 32. The collars 39 have outwardly extended projections 40. Levers 4| of the first order are provided and are located on opposite sides of the stall posts 2. The levers 4| are fulcrumed at 42 on bolts or the like, carried by the stall posts 2. At one end, the parallel levers 4| are pivotally mounted on the projections 40 of the collars 39 and are held thereon by cotter pins'43. The opposite ends of the levers 4| are pivoted on projections 41 carried by collars 45 slidably mounted on downwardly extended sure stops 46 located between the stall posts 2 and the stanchion members it. Cotter pins 44 in the projections 4'! of the collars 45 hold the ends of the levers 4| on the projections 41. The upper ends of the sure stops 46 are pivoted at 48 to brackets mounted on the stall posts 2.

The general operation of a device of the class described is well known. By means of the lever l6 and the link H, the slide rods I cmay be operated to' open and close the movable stanchion members l9, through the instrumentality of the connectors l8.

Sometimes it isdesired that one of the movable stanchion members Ill be held closed, in order to keep in a particular cow. In the ordinary operation of the device, the locking pin 26 is pulled to the left, into the dash line position of Fig. 7, the locking pin then hanging in the hollow head 22, because the enlargement 21 of the looking pin is big enough so that it cannot pass through the circular portion 23 of the key hole slot in the hollow head 22. When it is desired to hold any movable stanchion member W in the closed position shown in Fig. 6 of the drawings, the locking pin 26is shoved to the right in Fig. '7, until it extends through the openings 25 of the track rails 4, the bit 28 on the locking pin passing into the head 22 through the reduced part 24 of the key hole slot. Because the handle 29 on the locking pin 26 extends into a direction opposite to the bit 28, and because the handle 29 is heavier than the bit, the handle tends to rotate the locking pin 26 into the position shown in Fig.

7, the bit 28 then extending upwardly and being engaged'within the hollow head22. In order to withdraw the locking pin 26, the locking pin may be rotated by means of the handle 29, until the bit 28 extends downwardly, and then the locking pin can be shifted from the solid line position of Fig.

7 to the dash line position of that figure, the bit 28 passing outwardly through the reduced slot '24 of the head 22, the enlargement 2'! of the looking pin engaging within the head 22 and holding the locking pin in the inoperative position depicted in Fig. 7.

When the rods |5 are shifted lengthwise, swinging motion will be transmitted to the sure stops 32 and 46, the levers 4| transmitting motion from the sure stop 32 to the sure stop 46. The particular way in which the levers 4| are connected with the sure stops 32 and 46 adds to the efficiency of the device and results in a construction which is well adapted to withstand long continued use, without expert attention.

. the beveled or inclined surface 5|] and drops over the upper end of the'part i4. Thus the stanchion member H] which has been released individually is-coupled automaticallyagain with the operating mechanism represented by the rod-s I5 and the connector I 8.

Having thus described the invention, what is claimed is:

1. In a stall, a guide comprising upper rails having openings, first and second stanchion members, the first stanchion member being movable between the rails, toward and away from the second stanchion member, means for attaching the second stanchion member to the guide, a hollow head secured to one rail and having a key hole slot comprising a main part and a reduced extension, a locking pin mounted in the openings and in the main part of the key hole slot and engaged with the first stanchion member to prevent the first stanchion member from moving away from the second stanchion member, the pin having an upstanding bit engaged within the head, to prevent the withdrawal of the pin, the pin having a depending handle constituting a weight that holds the bit in the position stated, the pin being rotatable to align the bit with the reduced extension of the key hole slot, whereupon the pin may be withdrawn from engagement with the first stanchionmember, the pin having a terminal enlargement of such size as to pass through the openings but to engage in the main part of the key hole slot, thereby leaving the pin hanging from the head.

2. A stall constructed as set forth in claim 1, and wherein the means for attaching the second stanchion member to the guide also holds the head on said one rail. r 3. A stall comprising a base, a top guide, a stanchion post extended between the base and the guide, an upwardly extended sure stop on one side of the post and having its lower end pivoted to thepost, the upper end of the sure stop being movable in the guide, means connected to the upper end of the sure stop for swinging the'sure stop toward and away from the post, a downwardly extended sure stop located on the opposite side of the post and having its upper end pivoted to the post, collars slidably mounted on the sure stops, intermediate the ends of the sure stops, the collars having outwardly and oppositely extended projections, and levers disposed side by side and located on opposite sides of the post, the levers being fulcrumed intermediate their ends on the post, the ends of the levers being secured on the projections of the collars for pivotal movement.v
