, STANCIIION.

Application led November 23, 1909. Serial No. 530,414. n

To all who-mit my'concern: y

Beit known that I, AHENRY L. FEnRIs, a citizen of the United States, residing at Harvard, in the county of McHenry and State of Illinois, have invented a new 'and useful Improvement in Stanchions,of which ,p the following isa specification.

My: invention -.relates to new and useful Improvements -In stanchi'ons, andv 1s fully described and explained in the specification f .n and shown 'in the accompanying drawing, in which- Figure 1`is an elevation ofmyimprovedl stanchion showing the position which the parts occupy in use, and, In' addition, In

dotteddines, amovable side in its open position; Fig. 2 is a detailed transverse section 'of the upper portion of the stanchi'onnthe closed position being indicated in solldlines and the o en position in dotted llnes; kFlg.

3 is a. section on the line 3 of Fig. 2; Fig. Il:v

re secured the supportingfchains of the" stanchion, andthe said' brackets arefadjustL able uponV their respective tubes in order that the stanchion may be at all times properly balanced, whatever be the position of itsstationary, but adjustable, sides.

C is the stationary side of the stanchion,

the same being formed'of an outwardly fac'- ing met-al channelif-l beam of U-shaped cross 4section secured to the top and bottom of the if? stanchion by bracket c, held in place by set v sizes.

screws and capable of adjustment to accommodate thest-anchion to animals of different As this stationary side is adjusted it will be obvious that the center of gravity of the'stanchion will be shifter-h and it is to permit the stanchion to be sup ported at all times in line with the center 'of gravity that the brackets a, b are made adjustable. D is the movable side oi the stanchlon,

which,y is made in the form of au outwardly-A opening channel bar, the cornersof which 'wir s o'i U-shapein cross-section, in order il are rounded so that the narp corners shall be brought in conact with the necks of the animals held by `the stanchion.` The Patented Aug.; 1911i pivotal supportof thewmovable sideof-the V stanchion 1s furnished by'a-bracket al, rightangled in form, one endv of which isy introf' duced into the correspondingA end `O the .`botto1n-tube `A of thestanchion, and they other end of which is turned Vup .and pivl oted between the flanges vvof the movable member D of the stanchion.

stanchion lies a locking-bar E, at the end v 'of which is a downwardlyfturned hook e Within the tube B at the top offthel and which is provided, ata distance from i that' hook, with an upwardly-projecting shoulder e1. The locking-bar is provided with a downwardly-extending `handle E1,

which is slotted at e2, a pin e3 ext-ending through said slot and being secured between .flanges of the channel-bar which forms the .movable member D of thestanchion. The

handlel ljll'is'cast with a bore e* which recelveswithin it a spring e5, the tendency of which is to rotate the locking-bar and its handle about the pivot formed by the pin e3 1n such a direction as to press the lfree end of the locking-bar downward, and when the handle is depressed it will be evident that the spring will be compressedV and the hooke tube B is traversed near that end adjacent to the movable member of 'the stanchion by, a

pin F in position-to be engaged by the shoulder e1 upon the locking-bar.

The ,operation of the device will now be Jreadily apparent. W'hen the device is closed, pressure upon the handle will disengage the hook at the end of the locking-bar from the end of the. upper member of the stanchion with which it normally engages, per? mitting the movable member of' the stanchion to be swung outward laterally, so Vthat an animals head can pass between the side lmembers of the stanchion, either 1n entering :or leaving. The device can be closed with the greatest ease by simply pushing the movable member inward, and in such closingl the .locking-bar will, of course, be continuously guided by the tube'within which it lies, so that no manipulation is necessary in closing the stanchion eXcep-t to push the movable member. The engagement of the pin F with the shoulderupon the locking-bar obviously prevents the movable member from swinging open too far. ,I

The device is advantageous because of its end' ofthe locking-bar raised. The

simple construction,- because 4of the adjustable features embodied in it, and because the locking-mechanism is entirely closed and is continuously: guided by the inclosing-tube from its open. position to its closed position.

It is thus apparent that no matter how loosea singleand simple manipulation;

I realize that considerable variation is possible in the details of construction of my lmproved device, Without departing from the spirit of my invention, and I do not intend, therefore, to limit myself to the specifioform herein shown and described.

, What I claim as new and desire to secure by Letters Patent is y y Y In a stanchion, tubular top and bottom bars, slidable brackets on said bars, a side bar connected to said brackets, means forseslot and pin connection` therewith and the bottom bar, a locking bar adapted to'pass through -saidtop bar and having a handle portion mounted on said side bar and having curing said brackets in adjnstedlposition, aj, second side bar-pivoted 'at its lower end to vided at its forward end with a hook adapt- 1 ed to engage the outer end'of the top bar,

a shoulder in the rear of said hook,.a stop adjacent .the forwardend of said top bar wherewith said shoulder is adapted to engage in the withdrawal movement of said locking bar', aspring-carrying bore on said,

handle located below 4ite slotted connection with lthe side bar, a spring in said bore, whereby the hook end of said locking bar is caused t-oengage the outer end of the tubu lar top bar, and to be disengaged therefrom when said handle is depressed, Lfor the pur pose Set forth.4
