STANCHION.

Specification of Letters Patent.

Patented Nov. 1, 1913.

Application filed July 1, 1912. Serial No. 706,925.

To all whom it may concern:

Be it known that I, GUSTAVUS TARCZA, of the town of Litchfield, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Stanchions; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the referencenumerals marked thereon, which form part of this specification.

My present invention relates to stanchions having a movable side which is adapted to be moved toward or from the fixed side of the stanchion and at all times have the two sides substantially parallel to each other.

The object of my invention is to provide a stanchion of this class which is simple in construction and efficient in operation and not likely to get out of order.

A further object is to provide such a stanchion wherein the power to open or close the stanchion is applied near one end of the movable side and further separate means are provided for keeping the movable side parallel to the fixed side.

A still further object is to provide such a construction and such means of moving and equalizing the movement of the movable side as shall be adapted for use with what is commonly known as a swinging or pivoted stanchion.

Figure 1 is a front elevation with some parts broken away of a stanchion embodying my invention. Fig. 2 is a front elevation of the stanchion shown in Fig. 1 when the parts have been moved to open position. Fig. 3 is a horizontal sectional view on line 33 of Fig. 1. Fig. 4: is a horizontal sectional view on line 14 of Fig. 1. Fig. 5 is a horizontal sectional view on an enlarged scale on line 55 of Fig. 1.

Referring to the drawings in a more particular description the stanchion proper consists of a fixed side 8 rigidly connecting the top 9 and bottom 10 and an oppositely disposed movable side 11 which is mounted to be moved toward or away from the fixed side as by having the ends of said movable side slidingly mounted in slots 12 and 13 in the right hand portions of the top and bottom respectively. At a point 14: a little below the top 9 there is pivotally connected to the movable side 11 a link 15 having its other end pivoted at 16 to the upper end of a lever 17 which is fulcrumed at 18 to the fixed side 8 and has its lower end extend below said pivoting point 18 and to the outside of the fixed side. A lever 19 pivoted at 20 to the bottom 10 has at 21 a sliding pivotal connection with the lower end of lever 17 and continues thereabove: some distance for suflicient operating leverage and may conveniently have its upper end extended into a slot 22 .at the left end of the top 9. It will now be obvious that by reason of the connections formed therebetween by lever 17 and link 15 moving the lever 19 away from the stanchion or to the left as seen in Figs. 1 and 2 will communicate an outward movement to the upper end of the movable side 11 and that a reverse movement of the lever 19 will cause said upper end of movable side 11 to approach the fixed side 8.

In any stanchion it is very desirable to have the movable side substantially parallel at all times to the fixed side as this provides a larger opening for the admission of the cows head when the stanchion is in open position and avoids the accidental premature closing of the stanchion by the cow raising her head against a slanting movable side such as is commonly used when the movable side is pivoted at its lower end. I have further found that to obtain such a parallel movement of the movable side by means heretofore in use that will impart a similar amount of movement to both ends of the movable side from one operating lever or other means has marked disadvantages. One disadvantage is that any such levers or connections will be either too complicated or extend farther beyond the outline of the stanchion than is practical. A further disadvantage is that any such direct powercommunicating means to the lower part of the movable side is apt to be in the way of the cattle or be injured or broken thereby. In order to obviate these disadvantages I apply my power directly to the upper end only of the movable side and provide further or separate means operated by the motion of said upper end to obtain an equal movement of the lower end of said side. Further in order to obtain simplicity in this equalizing device I employ an equalizing device that operates in one direction only and use a resilient member for the return movement. Such an equalizing device comprises a flexible member 23 which is fastened at its upper end at 2% to the top 9 at the right hand end of the slot 12 and extends thence over a roller 25 suitably mounted near the upper end of the movable side 11 and extends,

thence downwardly preferably housed with in a groove 26 in the rlght edge of said side,

thence below a roller 27 suitably mounted cured at one end at 30 to the right end of slot 13 and at the other end to the movable l side near its lower end as by means of a yoke 31 between the forks of which the flexible member 23 may conveniently pass. This resilient member 29 is tensioned to draw the lower end of the movable side away from the fixed side.

follows: An inward pressure applied to the operating lever 19 or an inward pressure applied directly to the upper end of the movable side 11 will cause said upper end to move inwardly or toward the fixed side. Such inward movement of said upper end will cause an upward movement of the flexible member 23 in the groove 26 and in an obvious manner through said flexible member being anchored at its lower end will cause the lower end of said movable side to move inwardly to the same extent as its upper end. It is assumed of course that the power applied is sufficient to overcome the slight resistance of the resilient member 29. When the stanchion has been thus brought to closed position as indicated in Fig. 1 it may be conveniently held by means of a gravity catch 32 pivoted upon the top 9 at 33 and having an angled face 34 adapted to drop against the upper right hand corner of the movable side. In moving the stanchion from closed to open position its operation will be as follows: First; the catch 82 will be unlocked by having its face 34: moved upwardly by the handle 35 of said catch, then an outward pressure will be applied either to the operating lever 19 or directly to the upper end of movable side 11 thereby moving the said upper end outwardly. At the same time the flexible member 23 will be allowed to freely move downward through the groove 26 allowing the lower end of said side to move outwardly under the tension of the spring 29.

It will be obvious that the stanchion now described may be such as are known as fixed stanchions and have the top and bottom long members common to several stanchions. It will be further noticed however, that my invention is particularly adapted for use with a swinging stan hion in that the parts.

are so arranged and operated as not to prevent at any time the free rotation of the stanchion and so that the rotation of the stanchion in its frame work does not interfere with the operation of the movable side or any of its connections.

As illustrated in the drawings my stanchion may be pivotally mounted upon any suitable frame work by means of a pin 36 projecting from the bottom 10 into a base board 87 and a bolt 38 extending upwardly from the top 9 into the top piece 89 of the frame work. Uprights 4:0 may be used in the ordinary way to support the top piece 39.

As seen in Fig. 1 it may be particularly noticed that when my, stanchion is in closed position the lever 19 stands closely against the fixed side 8 and the lower end of lever 17 does not project therebeyond. On the outside of the movable side 11 there are no projecting parts of any kind. It will be seen therefore that with the stanchion in closed position there are no parts or projections eX- tending abruptly beyond the sides of the stanchion to interfere with the cow reaching 4 around the stanchion on either side. It will be further seen that in closed position practically the full space between the sides is available inasmuch as the link 15 is now j raised to its upper position close to the top 9.

When the stanchion is in open position the operating lever 19 extends somewhat to the left of the stanchion proper and thereby practically prevents the cow putting her head to the left of the stanchion while the movable side is so far to the right as'to prevent the cow getting therebeyond on that side. Upon the cow putting her head into the proper opening between the two sides of the stanchion any upward pressure of her head or neck against the slanting side of the upper end of lever 17 operates to partially or wholly close the stanchion.

What I claim as new and desire to secure able side in the opposite direction when the upper end is so moved, said resilient member and equalizing member operating to keep said movable side parallel with said fixed side.

2. In a stanchion, a top, a bottom, a fixed side, an oppositely disposed relatively narrow side slidingly mounted in said top and bottom, means including a link and lever operatively connected to the upper end of said sliding side whereby movement of said lever will operate the upper end of said movable side, a resilient member tensioned to move the lower end of said movable side outwardly and a flexible equalizing member adapted to move the lower end of said movable side inwardly when its upper end is so moved, said resilient member and equalizing member operating to keep said movable side parallel with said fixed side.

3. In a stanchion, a top, a bottom, a fixed side rigidly connecting said top and bottom, an oppositely disposed relatively narrow side slidingly mounted in said top and bottom, means including a link and lever operatively connected to the upper end of sald sliding side whereby movement of said lever will operate the upper end of said movable side, a resilient member tensioned to move the lower end of said movable side in one direction and a flexible equalizing member adapted to move the lower end of said movable side in the opposite direction when the upper end is so moved, said resilient member and equalizing member operating to keep sacild movable side parallel with said fixed s1 e.

4. In combination a supporting frame and a stanchion pivotally mounted therein comprising a top, a bottom, a fixed side rigidly connecting said top and bottom, an oppositely disposed side slidingly mounted in said top and bottom, means including a link and lever operatively connected to the upper end of said sliding side whereby movement of said lever will operate the upper end of said movable side, a resilient member tensioned to move the lower end of said movable side in one direction and a flexible equalizing member adapted to move the lower end of said movable side in the opposite direction when the upper end is so moved, said resilient member and equalizing member operating to keep said movable side parallel with said fixed side.
