Specification of Letters Patent.

Patented Apr. 30, IMF.

Application filed June 23, 1916. `Serial No. 105,378.

To all wwm t may concern:

Be it known that I, EDWARD J. BRADY, a citizen of the United States, residing at Cedar Falls, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Stanchions, of which the following is a description.

My invention belongs to that general class of devices known as stanchions, and particularly a stanchion for holding cattle or the like. The invention has among its objects the production of a device of the kind described that is simple, convenient, durable, compact, efficient and satisfactory, for use wherever found applicable. It has particularly as an object the production of a stanchion of the kind described in which the upper ends of the stanchion members are double acting or both movable to open or close the stanchion, whereby stop bars or the equivalent are unnecessary, theconstruction of the stanchion itself preventing the cattle from passing on either side of same when the same is in open position. It also has as an obj ect the production of a stanchion in lwhich movement of one stanchion bar will impart movement to the other bar, so that when one bar is moved in either direction the other will move correspondingly in the opposite direction, whether in opening or closing the stanchion. It also has as an object the production of a device in which opening movement of the stanchion will be limited so that cattle cannot pass through and between the bars beyond the desired point. Many other advantages and objects of the y construction will appear to those skilled in the art from the disclosure herein mentioned.

To this end my invention consists in the :novel construction, arrangement and combination of parts herein shown and described, and 4more particularly pointed out in the claims.,

In the drawings, wherein like reference g parts,

Figure 1 is a view in elevation of my preerred form of stanchion;

Fig. 2 is a sectional view taken substantially online 2-2 of Fig. 4;

Fig. 3 is a view similar to Fig. 2, the ends of the stanchion members and latch being shown in elevation;

Fig. 4 is a sectional view substantially on line 4-4 of Fig. 3;

Fig. 5 is a sectional view substantially on line 5 5 of Fig. 3;

Fig. 6 is a perspective view of one of the stops or closures arranged one at each end of the head bar, and

Fig. 7 is a sectional view taken substantially on line 7-7 of Fig. 8.

Referring to the drawings, in which the preferred form of' my device is shown, I have shown a portion of the stall construe tion, consisting of the bar 1, supports 2 and 3 therefor, and curb 4, it being understood that this is only for the purpose of illustration, as any shape or size or make of stall construction and the like may be employed. My improved stanchion consists of the members or bars 5 and 6, which are preferably brought together atv their lower and upper ends. The lower ends may be connected together in any suitable manner. As shown, they are hinged together at 7. At the upper end of said members are arranged the heads 8 and 9, which carry the extending parts 10 and 11, formed integral therewith or separable, as shown. Arranged at the upper end of the stanchion members, and slidably carryingthe same, is a tubular member or head part 12, which is slotted on its lower face, the same being arranged with guides 12 (see Figs. 4 and 5) which are formed at one or both sides of the slot 13. The members 10 and 11 are projected into space in the bar 12,`and are formed as at 10 to overlie and slidab-ly engage the guides 12. Members 10 and 11 are provided with openings 14 and 15 respectively through the same, through which projects a bar or member 16, which is spirally twisted in opposite directions from the center toward each end so as to form substantially a thread 17 and 18. Any equivalent construction may be employed, but the twisted type of bar shown has been found to be particularly eflicient and inexpensive to manufacture. The twisted part forms substantially a thread, and the same is of light weight and operates freely. I show the head bar 12 provided with a supporting ring 19, by means of which the same may be suspended, as hereafter described. Obviously any equivalent may be employed for the head bar 12, for connecting the twisted bar 16, or ends of the stanchion members to the stall frame.

I preferably make the head bar or member 12 shown of sheet metal, bending the edges down, and thence inwardly, forming the flanges 12 and slot 18. The ends of the member are provided with end walls or plates 29, which may be secured in place in any desired manner. As shown, I form the same with the projecting tongues 30, which may be extended through openings in the member, and then upset or riveted down at the ends so as to securely lock the same in place. The end plates 29 serve as stops for the upper ends of the stanchion members when in their open positions, and also secure and reinforce the member 12, as mentioned.

To secure the members together in the operative position shown in the full lines in Fig. 1, I provide a latch member preferablv carried by one part and arranged to engage the other part. rIhe latch member shown comprises the member 23, pivotally secured to one head member 8 at 2i, the same being provided with one or more (as shown 2) extending engaging members 2G, shouldereds at 27 so as to engage the outer side of the member 11. The latch member is provided with an extension or handle 25, by means of which the same may be controlled and raised out of engaging position. A spring 28, or equivalent means, may lbe provided, if desired, so as to normally maintain the latch member in its engaging position. I have shown the bar 12 supported by the link 33 and eye 34, carried by the stall frame, the lower end of the stanchion being secured or anchored to the front curb by the chain 35, or equiva lent means for the purpose.

Y The operation of the device may be briefly described as follows: Assuming that the stanchion is as shown in the full lines in Fig. 1, the same may be opened by unlatching' or disengaging the latch extension or member 26 with the member- 11. Either of therstanchion members 5 and 6 may be moved toward the end of the head 12, or in some Vcases the same may drop, due to its weight, the ends being supported and guided by the guides. However, movement of one part causes a rotation of the twisted bar 16, and this causes the other bar to move, the'end of the bars acting substantially as stationary nuts, which are not rotatable but moved by the rotation of the screw. The bars 5 and 6 maybe moved or dropped'to the position shown by the dotted lines in Fig. 1.V This permits the stock to be released and the stanchion may remain open until it is again desired to lock the stock in the stall by the same. It will be noted by referring particularly to Fig. 1, that the stanchion members, by moving to both sides, make the use of stop bars or the like unnecessary. The stop bar, as provided, is ordinarily spaced between one stanchion and the stall side when only one stanchion member is adjustable or movable, so that stock will not pass through between the other side of the stanchion and stall.

lVith the present device herein described the stanchion members. since they both move, in themselves act as stop bars, and prevent the cattle from pushing their heads past the stanchion on either side between the stanchion and stall frame. Further, by opening both stanchion members the stock always inserts its head between the members. so that no time is lost in locking or unlocking the stanchions when the cattle are not in place. There being no stop bars or the like the cattle are free to turn their heads or otherwise move about the stall withoutdanger or injury, and with greater comfort. The mattei' of comfort is not a small matter, as tests have shown that dairy cattle increase their yield of milk when well taken care of and kept comfortable. The question of expense or economy is of importance, as the stall may consist of a minimum of parts.

Having thus described my invention, it is obvious that various immaterial n'loditications may be made in the same without'. departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described and uses mentioned.

lVha-t I claim as new and desire to secure by Letters Patent is 1. A cattle stanchion comprising a pair of coacting members pivotally connected at the lower ends, in combination with a cooperating member constructed on each side of its middle with a reverse twist to form a threaded member, said member being operatively connected to the said members at their upper ends and having free laterally movable portions capable of bodily defiection, and stops for restricting endwise movement of the same.

2. A cattle stanchion comprising an elongated pair of co-acting bars pivotally connected at the lower ends, carrying at their upper ends extensions, in combination withl a supporting tube longitudinally slotted on its lower face with the extensions extended therethrough and located within the tube, said tube permittin the cooperating bars to slide back and fort therein in the opening and closing movements of the same, in combination with a reversely twisted member operatively engaging the extensions, substantially as and for the purpose set forth.

8. In a device of the kind described, a pair of cooperating stanchion bars 5 and 6, pivotally connected at their lower ends and provided at their upper ends with extensions lO-ll, having formed therein slotted openings irl-l5, in combination with an elongated supporting tube l2 longitudinally slotted on its lower face through which extend the members 10-1i, said tube permitting the cooperating bars to slide back and forth therein `in the opening and closing movements of the same, a cooperating screw member transversely twisted from near its center toward the ends positioned in said slotted openings laf-15, and a latch member for locking the upper ends of the stanchion bars together when desired, substantially as described.

Ll. The combination with stanchion members connected for opening and closing movements toward and from each other, and means for locking said members in closed position, including locking projections on both members, and a common latch pivoted at its lower end to one of the members and at its upper freeend provided with portions for engaging over both of said projections to prevent separating movement thereof.

5. The combination with stanchion members connected together to have swinging movements toward and from each other in the opening and closing thereof, of an approximately straight hollow member into which projecting portions of said stanchion members project, means within said hollow member carried solely by the stanchion members for compelling opposite opening movements of the stanchion members, and means for suspending the stanchion to permit the swinging movements of the stanchion members, while maintaining engagement of said extensions with the hollow member.

6. The combination with stanchion members connected together for movement in opening and closing the same toward and from each other, a hollow member into which extensions of said stanchion members project, said extensions carrying an otherwise free device for compelling opposite movements of the stanchion members upon movement of one of them.

7. The combination with stanchion menibers connected together for movement in opening and closing the same toward and from each other, a hollow member into which extensions of said stanchion members project, said extensions carrying an otherwise free oppositely twisted device for compelling opposite movements of the stanchion members upon movement of one of them.

8. The combination with stanchion members pivotally associated for swinging movements toward and from each other in the opening and closing movements thereof, of an approximately straight hollow member into which extensions of said stanchion members project and with which said extensions are interlocked for sliding movement, a device within the tubular member supported by said extensions adapted to cause opposite movements of the stanchion members upon the movement of one of them, and means for suspending the stanchion to permit the swinging movements of the stanchion members while permitting the interloclred sliding engagement of their extensions with the hollow member.

9. The combination with stanchion mem'- bers pivotally associated for swinging movements toward and from each other in the opening and closing movements thereof, of an approximately straight hollow member into which extensions of said stanchion members project and with which said extensions are interlocked for sliding movement, a device within the tubular member supported by said extensions adapted to cause opposite movements of the stanchion members upon the movement of one of them, and means for suspending the stanchion to permit the swinging movements of the stanchion members while permitting the interlocked sliding engagement of their extensions with the hollow member, said device comprising oppositely twisted portions.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
