['0 LZZ wim/m, 'it may concer/n Be it known 'that l, lov W. S'rnvimson, a citizen oi? the United States, residing at l-larvard, in the county ot lillclwlenry and State et llllinois, have invented certain new and useful improvements in Stanchions, oit which the following is a description.

ll/ly invention belongs to that general class ot devices particularly adapted for securing cattle .in their stalls, and has l'or` its object the production ot such a device that is simple and ell'ective in operation, and which possesses peculiar advantages in the method and convenience oli operation. To this end my invention consists in the novel construetion, arrangement and combination oit parts herein shown and described, and more par* ticularly pointed out in the claims.

lln the drawings, 'l indicates the :door ol' the stall, which the other end, `or the end near the animals head,` preferably raised to ttorin a base wall 2, carrying the stanehions. 3 indicates a division bar between, the stalls .separatingI the animals, and also serves brace to rigidly :support fthe `structure carryinap,P thestanchions. .l-ltiare substan 19er. serial no. aviator.

tially vertical tubular members which at their lower ends are rigidly connected to the ed base if), and above the stall divisions 3 are ri gidly connected. ln the preferred con struction shown, the members l extend outwardly `trom each other near the bottom and are thence inclined upward toward each other, at or near their meeting point being bound togrether by a. suitable coupling member 5 (Figures l, 3 and ll). rllie inclination ot' these two members l is substantially parallel with that of the approximate stanchien bars Ll when the latter are open, orming` what is sometimes called a sure stop to prevent the animal passing its head between said supports Ll: and the stanchion as the `animal enters the stall (see dotted lines,

Figures l and 3.) Abo-ve the coupling the two bars or tubes 4t are extended upward to the desired height, and at the upper end rari-y the member (i which secures the two 'te' -l toggjetber and rigidly engages them with a horizontal bar 'l'. The bar 7 pre- 'lierably angular or irreggl'ilarly formed s0 as to maintain its position and properly and non-rotatively support the various parts in suitable ali ,ggnment rlhe structure thus 'lia-r described rigid in its nature and consti tutes the traine worlr of my improved device.

8--8 are 'the stanchion bars which are supported and depend from the top structure. lliese are ordinarily metal tubes and may, ilIv desired, be 'provided with wood or other 'suitable linings 9 upon the inside. rl`he members 8 are pivotally supported at the top on members l0-l0?, which are slidinpD'ly mounted upon the horizontal bar 7. The lower ends oif members @-8 are pivotally connected to a link member 11 so as to allow the upper ends to be separated as indicated in dotted lines, said link member beiV n; provided with an extendingf boss 1Q which .loosely `positioned within a compiufativcly large recess 1S 'formed in the hase 2, so as to allow the lower endroit the ffstanchion to have a limited. inoveinent transverselv the stanchion, and at the sarnetime permit-ot a limited pivotal movement oli the `entire stanchio-n when it is closed, pro vidinn` 'tleribility oil `movement very advangreons in devices ol' this character. A i, 1... l!- may be secured upon the support it desired, to restrict the movement and prevent undue wear. e

. it:suitableI points upon-tbe horizontal bar yat a point between its ends as at 22.

7 are rigidly secured guides 15 (Figures 5 and 10) which slidingly Support a master rod or bar 16. These guides are positioned between the meetingor approximate upper ends ol? the stanehion bars 8, and when all are suitably locked, serve as ay stop to prevent movement upon the bar 7.

lAt one end of the section a bell-crank lever 17 is pivotally supported at'18 and is,

connected by a link 19 to the sliding master bar '16 (lligur'es 1, 2 and The operation of the lever, 'therefor-e, serves to control the movement of the master bar 16 back and orth in its guides.

Rigidly secured adjustably upon the bar 7 near each stanchion, but on the side opposite the lever 17, is a sleeve or collar 20, slide-ble on the bar 7, and which at a point preferably, below the bar 7 pivotally supports a lever 2% linl-z 23 for each stanchion is pivotally connected as at 24e with the approximate end of the lever 21, and at its other end is connected to the supporting parts l0a so that as the master bar 16 is longitudinally moved, it will oscillate the lever on its pivotal support. The opposite end of the lever which extends upon the other side of the bar 7 is pivotally connected as at 25 to a link 26 which is extended and pivotally connected asV at 27 to the part 10 rot the stanehion nearest to the lever 17 or on the opposite yside of the dividing piece 15.

to Abe brought into engagement with a pin 29 or equivalent member carried upon the ,supporting member lOfl of the stanchion bar opposite to the lever 17. It is obvious therefore' that the swinging` of the lever 17 will cause the oscillation of the bar 16, and the .members 10L with which the locking inemher Ll() is connected. `lever 21. which at its opposite end, by means l ofthe link 26, will throw the cooperating' This will oscillate the member 10 in theopposite direction, moving; the top ol the members 8 apart, as indicated in the dotted lines, and opening the stanehion. This would be the operation. un-

` less the two .members 'l0 were locked to ejetlier. In the preferredikconstriietion, a locking member `is provided for that pur pose, when desired to prevent accidental separation of the' parts and for the further purpose of locking certain stanehions firmly together, while other stanchions may be opened by operation of the bar.

`In the simple form of locking member illustrated, a slotted bar 30 is pvotally supported as at 31 upon one ol` thel members. as 10, while the cooperating;v member is pro vided with a cooperating pin lt is thus apparent that if the locking member il() is engaged with the pin 32 and the loelringr member fl() is disengaged l'roni the pin 2S), the operation oit the lever will reeiproeate the bar 16 without affecting the stanehion bars locked together, as indicated at the left in lull lines on Figure l. (.)n the other hand, if the locking member 30 is disengagged from the pin 32, while the laleh Illl engages the pin 29, a reriproeation of the bar 1G by the lever will oseillate the lever 21 upon `its pivot.y and through the link eonnection described, will more the parts lll apart from or toward each other and the support 15, as indicated in Figure 6.

The advantages oit this form ot construetion are many, In the first instance. when the tops of the stanchion bars are loeked together as indicated in Figure 2` the danger of accidental disengagement and opening is very remote, and a degree olt security is gained which is important in this line of industry. The bar 17 also throws by its center 18 in such manner as to add to this security. Il: now it is desired to release all of the cattle held in the section` the attendant moves alongr on the opposite side and disengagjes the several latches il() Vl'roni their Cooperating' pin 32. as indicated in full lines in Figure 6 and in dotted lines at the right in Figure 1 and the lel't in lfhrnre il. 'lhe operation of the lever will then simultaneousl)v open all the stanchions, as indicated in dotted lines. and release the cattle. ll on the other hand. it is desired to release but a portion or a part of the cattle thus eonined, the attendant will simply operate the latch 30 upon those stanehions where il is desired to release the cattle. at the saine time disconnecting the latch 40 from ils engaging` member 29. The movement. ol they bar will then serve to open the stain-lilou where the latch 30 is disconnected, while all others will be maintained in a elosed and locked position as indicated in Figure 'l where the open stanchion .is shown in dotted lines.

It at any time it is desired to releasey but a single animal. the all'einlant may release both latches Il() and lll. when the upper ends ol the stanchion bars may be readily moved apart and the animal released without in any way ii'iterferinn; with the other eonnee tions. Likewise. a sinefle animal may be se cured by reversing the operation just described.

When the stauehions are secured together as indicated in Full lines1 a limited pivolal movement ot the stanchion is permitted by reason of the pivotal Connection ol the upper part of the stanchion with the supportinglr members 10-10, which is not interfered with by the loose connection at the lower .l lll tia/insel end of the stanchion. llVhen the stanchion is open however, as indicated in dotted lines, it is supported at three points as indicated, and these points are somewhat Widely separated. rl`he pivotal :lunction in this position is substantially eliminated, rendering it impossible for the stanchion to turn upon a vertical pivotal point which might interfere with the proper engaging of the neck of the ani mal therewith. As belore stated, when in the open position, the inclination of the stanchion bar 8 and the supports l are such as to form a sure stop and to insure the proper positioning or' the animals neck in alignment with the stanchion.

llt is obvious that an equivalent construe tion of many parts will Serve the same pun pose the details above simply describing the preferred form illustrated.

Having thus described my invention, it is obvious that various immaterial modifications may be .made in the same Without departing from the spirit of' my invention; hence l de not Wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
