' Y sIeivoR To SAID ounnin' I CATTLE smaltoIIIo'ivVV Appl-mamme@ December 21,vv ree?. serial Np.'Y 241,'5o4f 1 pivotally mounted neck bars, .provided at their upper ends with arms pivoted thereto and to each other. common pivot point between the arms, the neck bars are swung relatively to the head to enlargev or .diminish the space therebetween into which the vneck of the animalis to be received. The vinvention further pro`V vides a simple mechanism for displacing the above mentioned pivot point y1n the manner desired, and this mechanism'is preferably,v

controlled by an operating lever.

A The invention is fully disclosed by wayof example in the following'description and 1n the accompanying drawing, .1n which- Vligurel is a front elevation of the devicev in closed position;

F ig. 2 is a section on the line 2-42 of Fig-k ure 1; and

YI4`ig'-3 is a section on the line of vFig-v Lure1.f

Reference to these views will Vnow be madeY by use of like characters whichV are employed to designate corresponding parts throughout. The device is supported in a frame consist-y ing of a base member 1, a pair of uprights or standards 2 secured thereto, anda pair of rails 3 fixed across the standards in the same horizontal plane and near the upper ends f thereof. A hollow head 4, preferably a metall-ic member, is suspended from the rails by a pair of chains" 5 attached to opposite sides thereof and anchored as at 6 in lthe rails.

Within the hollow member lare pivotally Y vided with chains 27 attached to rods 28.011

mounted a pair of neck bars 7 in such a manner that the upper ends thereof are free and protrude above' the upper edge of the head 4 as shown in Figure 1.

Several holes 8 are formed through the The operative parts of the present device?` include a head supporting a pair of spaced,

On displacement of theV `head for accommodatingthe ,pivot pins 9,2 whereby the normal spacing between lthe neck.v bars may be varied accordlngto the particu'-A lar'adjustment.l The upper ends of the bars are bifurcated as at 10 forthejpurposes*of-re-` ceiving arms 11 pivotally .connected therein of the-bars andhave their inner-.ends pivotallyconnected to each otherbya -pin 13. The

outer ends of the arms are also provided each with a seriesy of apertures 14 for selectively receiving the pins 12, whereby the spacing of.

the bars 7 may be further adjusted.

"An arm' 15 has one end pivotally supported betweenthe rails 3 and the other end pro# yby pins 12.'. YThe'arms'll extendinwardly vided with a depending link member 16 which forms aboxor socket 17 'as shown more clear- L f Y.

ly in Figure 2.- A clip 18 ispivotallyheld'by`v the f'pivot" pin 13 ypreviously mentioned and t is equipped with a ball`19 receivedinfthe' socket 17 so thatl aA universal joint isjipro vided between the parts 16 and 18.

Theuprights 2 carry clips 20 above fthe; y

rails 3, and in these clips isslidably mounted an .operating rod v21.!` Alink 22 pivoted at both its endsV connects the rod to thenpivot point between the arm 15 and the link memj ber 16. l y- 'Froni .one of of thelever is attached'asat25 to the `rod21 I the standards2"extends/ai;` bracket'23havi'ng anV operatingllever 24'piv-v` oted,theretointermediate itsends. On'ekend"l 26.l It willbe apparent that by means of the operatinglever 'the'rod 21 maybe slid across the frame, in consequence of which the link l. f

member 16 will be raised or lowered according to the direction in which the operating lever is swung. This action results in a lifting or lowering of the arms 11 at their common pivot point, so thatthe neck bars 7 will v.

be expanded or contracted beneath the head 4' according tothe direction in which the operation is performed.

VThe lowerL ends of the neck bars are prothe base member 1 for the purpose of anchor- Ving these yends and yet' permitting movement In the use of the device, the normal spacing of the bars 7 according to the size of the animal is determined by adjusting the pins 9 and 12 in the selected apertures 8 and 14. In order to release the animal, or to initially permit him to enter the device, the operating lever 24: is moved to the dotted, line position shown in Figure l, whereupon the common Vpivot point of the arms l1 is displaced and the bars 7 are caused to diverge beneath the head 4. In locking the animal betweenthe bars, it will be obvious that a reverse movement of the lever 24 will close the bars on the animals neck. The opening or expanding operation cannot be initiated atlthe bars 7 for the reason. that such movement of the bars4 Will tend to lower the common pivot point. of.

thev arms ll, which now decline towards this pivot point, and will cause lthe point to bear upon a; heavy.V plate 29 secured on the upper edge of the head 4.

Although a speciiic embodiment of the invention has been illustrated and described, it will beunderstood that various alterations in the details ofV construction. mayv be made without departing from the scope of the in.

vention as indicated by the appended claims.

vWhat we, claim is l. A stanchioncomprising a frame, a fixed rail included in said frame, a swing'ablehead suspended from said rail, a pair of neck bars pivoted to, said head, arms pivotedAv to said bars and pivotally connected together, and

saA

means fon displacing the common pivot point of said bars, whereby to swing said bars relatively to said head. Y

2. A stanchion comprising a frame, afiXed railfinclnded in saidY frame, a swingable head suspended Afrom said rail, a pair of neck bars pivoted to said head, arms pivoted to said barsa'nd pivotally connected together, an arm pivotedj to said rail,1 a link connecting said last named arm to the common pivot point of the first'named-arms,and means for swinging saidilast; named armen its pivot'point, whereby;A to swing said bars relatively toisaid` head.
