This invention relates to multiple-operated stanchions for use in cow stalls, and is fully described in the following specification and shown in the accompanying drawings, in which:

Figure 1 is a rear elevation of the stall front with stanchion mounted therein, showing the stanchion closed;

Fig. 2 is a similar view showing the stanchion open;

Fig. 3 is a top plan view of the stall front slightly enlarged;

Fig. 4 is an enlarged partial vertical longitudinal section on the line at of Fig. 3;

Fig. 5 is a similar transverse section on the line 5 of Fig. 3;

Fig. 6 is an end elevation 01": the right-hand end of the stall front;

Figs. 7, 8 and 9 are sections on the lines 7, 8 and 9 of Fig. 3;

Fig. 10 is an enlarged partial section on the line 10 of Fig. 3;

Fig. 11 is a partial top plan view of the same; I

Fig. 12 is a partial vertical section on the line 12 of Fig. 10; and

Fig. 13 is a side elevation partly in section showing the bottom part of the stanchion.

The embodiment illustrated comprises a stall having a front made up of vertical pipes 10 and 11 which may be secured to a concrete curb 1.2 by any suitable means such as clamps 13. The top member of the stall front consists of two spaced facing U-shaped members 14: as shown in 5 which are secured to the tops of the pipes 10 and 11 by means of the spacer-clamps 15 and 16 and the bolt 17.

A stanchion A is hingedly suspended from its top by means of a swivel bolt 18 to a member 19 which is secured to-the spaced top memhere 14 by means of a bolt 20 as shown in detail in Fig. 10. The lower part of this stanchion is loosely connected to the member 21 by means of a pin 22 and chain 23.

p head 24: is s'lidably mounted between the spaced top members 14: and carries two parallel slide rods 25 which are guided in the casting 26 at the top of the pipe 10. The head 24 carries a pin 24: on which is pivotally mounted one end of the link 27 the other 1926. Serial no. 118,700.

end being pivotally mounted in the outer end of the crank 28 which is journalled on the upper end of the pipe 11 and retained in place by means of a set collar 29. An oper ating lever 30 is pivotally connected to the crank 28 by means of a pin 31 and has a' slot 32 which is adapted to fit over cit-her of the pins 29* or 29 on the two sides of the set collar 29. As shown in Fig. 1, the operating lever 30 covers the pin'29 The parallel slide rods 25 carry a casting which is adjustably secured thereon by means of set screws 34: and on this is carried a finger 35 which is p'ivotall'y connected by the pin 36. The free end of this finger is grooved upwardly and normally rests on top of the top membersle. I

In Fig. 1 the spaced slide rods 25 are at the extreme right-hand end of their throw with the operating lever 30 locked over the pin 29 while in Fig. 2 the rods 25 are at the eXt-remeleft of the throw with the lever 30 locked over the pin 29. In the latter position the finger 35 extends some distance beyond the extension 37 ot the upper stanchion member 38 which lies between the top members 14: and which is secured to the mov-' able stanchion member 39, the latter being pivotally mounted at 40 to the C-shaped stanchion 'frame 41. A spring 42 (see Fig. 13) tends to maintain the stanchion sidebar in an open position as shown in Fig. 2. The stanchion side bar 39 is p'ivotally connected at 43 to a slotted guide member 44 which extends throughthe hollow top member 45 and surrounds the bolt 46. As shown in Fig. 2 the guide member is at the outermost end of its stroke and is stopped by the bolt 46. As previously stated the extension 37 does not quite engage the finger 35 in this position.

To close-the; stanchioirfrom the position shown in Fig. '2, the lever 30 is raised until it clears the pin 29 and this lever is then swungflaround through an angle of substantially 180 to the position shownin Fig. 1. During this operation the finger 35 picks up the extension 37 and brings it up to theclos ing position wherein this stanchion 37 is substantially on the same axial line as the pin 18 so that in the closed position the stanchion A is free to swing about while in the open position shown in Fig. 2, it is held parallel to the stall front. A bar 47 is rigidly connected to the pipe 10 for pre venting the cow from getting her head through the stall front at the left of the stanchion and a bar i8 is pivotally mounted at 49 to the pipe 11 at the right-hand side of the stanchion, the upper end passing through the space between the top members M and resting against the head 2%. Grav'ity holds it in contact with this head so that it moves back and forth therewith.

It will be understood that the stall front and stanchion illustrated is only the righthand one of a series which may consist of two or more and that the other are substan tial duplications except for the matter of the operating lever 30 and the parts immediate ly related thereto. T op members 14" are secured to the ends of the top members l t by means of a filler member in and a bolt 14 Likewise the slide rods are secured to the ends of the slide rods 25 by gripping members 25* and bolts 25.

It will beunderstood fromthe foregoing that moving the sliderods 25 to the left movesall of the fingers 35 thereby permitting all of the stanehions to open simultaneously. Likewise moving the slide rods 25 to the right closes all of the stanchions.

If it is desired to open any of the stanchions while the others are closed, this may be done by raising the finger 35 for that particular stanchion. hen the slide rods 25 are again moved to the open position, the fingers 35 which are coneavely grooved on the lower surface, as shown in Fig. 10, and which have thus been raised to open one or more of the individual stanchions will pass over its extension 37 and because of said concave groove will be guided thereon and drop behind the extension 37, and on movement of this slide rod again to the right will close these stanchions as well as all of the others.

It is also sometimes desirable to retain one or more of the stanchions locked while opening the others, and for this purpose I have added a clip 50 which is jonrnalled on one of the slide rods 25 and-which has a shoul der 51 which engages a shoulder on the casting {2 so that while it is adapted to turn on the slide rod, it will not shift ondwise thereon. This cliphas an car 523 which is adapted to be drawn over in front of the extension 37 and to rest upon the opposite slide rod as shown in Fig. 11. hen this is done that particular stanchion will remain locked in closed position while the others not so locked vill open when the operating lever (is again moved to open position.

If desired, the link 27 (Figs. 1 and 3) maybe moved and placed on the opposite side of the post 11 in which case the operating lever 30 will then swing in the opposite direction from that which has been described.

A roller 24' on the pin 2 1 lies between the facing members 14 and serves to take the heavy lateral thrust of the link 37 wien a great number of'stanchions are set to be operated in series. This arrangement permits many more stanchions to be thus operated. 1

ll hile I have shown and described but a single embodiment of this invention, it is to be understood that'it is capable of many modifications. Changes therefore in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as disclosed in theappended claims.
