2' '0 all whom it may concern Beit known that I, CHARLES at Rockford, in the county of Winnebago and State of Illinois, have invented certa n new anduseful Improvements in Stanchions particularly to an improved stanchion, suptially on line 47-4 of Fig. 2;

porting means therefor, and means for simultaneously operating any desirednumber of stanchions of a series. has among its objects theproduotion of a device of the kind described that is simple,

convenient easy and positivein operation, durable, efliclent, ornamental and SLt1SfELC tory for use wherever found applicable.

More particularly it has among its objects the production of an improved: stanchion construction, preferablv double wacting, which stanchions maybe slngly or. simultaneously operated, and in whlch any oneor more of the same be locked shut and not be affected by the operation. of any others. It also has as an object the producy theends l1 and 12, which are provided with the

adjustable parts

13 and 14 and theparts l6 and 16 respectively, the samehavingthe tion of a construction of the kind described in which the stanchions may be adjusted for various sizes of stock. Many other ob- Figure 1, is a view in elevation from the,

Referring to the. drawings, inwhich the M. STEVEN- son, a citizen of the United States, residing 1 The invention double acting. stanchions. shownconsists of the parts 1 and2 suitably at their upper ends. 'llhe lower ends may lt ll tfiw beanchoredin any desired manner. 3 .As"

shown they are pivotally and adjustably sc' cured at 3 to a bare, provided with a stud or pin5 pivotally secured. to a ban? supported b the framepart 66. It is unnecessary to furtherdescribe theranchoring and construction of the lowerfend ofthe stanchion in detail, as the ban 7 forms a part of axseparate application. The frames 66: are preferably constructed as shown,

orin anrequivalent manner, and securedto the floor or curb in any desired manner. 1 shownythe two parts or legs 6 6 are connected by a preferably curved head consisting of a part orthe similarlyformed parts 88, or their equivalents, which may be secured inplacerby the bolts or screws 9, or equlvalent means for the purpose, The head parts 8 areformed s0 asto provide a slotl at thelower end andupper sides thereof.

The stanchionparts 1 and 2 are formed with projecting ends:21" and 21" arranged as shown. Part 16 i formed withthe gear. rack or toothed part 17 and part 16 with a similar rack 17', the two racks being spaced, as most clearly shown in 5 and 6. They arealso sllghtly curved as shown in the preferredconstruction. Arranged be tween the racks and carried by the head is a shaft 20, upon which i mounted a pinion or gear 19 arrangedto mesh with the

racks

17 and 17 Obviously, one stanchion part is moved it moves the rack connected therewith, and this, through the pinion 19, moves l the other rack in the opposite direction,

causing the stanchion parts to approach reach other orseparate, as the case maybe. Agshown in Fig. 1, the head is slottedas at 17 (on both sides) and ascrew or the equivalent passed through and into the rack. 1 These serve; as guides forthe free end of the racks and prevent the same from binding.

To simultaneously operate a series of stan ch1ons,I provlde an operatmg bar 22. The

bar 22 is slidably carried by the bracket 23, or its equivalent, supported in any desired manner, One of the projecting

parts

21 or 21, as shown 21, is provided with a latch member 24:, pivotally carried thereby, the same being formed with notches 24 on the opposite sides (see Figs. 1 and 2). The latch 24: is so pivoted to the extension 21 that it as is most clearly shown in detail in Fig. 6, in which latch 2st is arranged todetachably engage the bolt on bracket 25, which bolt also serves to lock the bracket on the rod 22. Any equivalent construction may, of course, be employed, Tn'this case bolt 26 is formed with the head 28 and provided with a spacer 27, or the equivalent, upon which the latch engages the nut 29, locking the parts to-- gether. A spring 30, or its equivalent, may be mounted on the bar 22 between the

brackets

23 and 25, the same tending to normally maintain thestanchions open or throw them to open position, as shown in Figs. 1 and 3.

Any number of springs may be employed upon the bar 22, one for each stanchion being shown. However, ordinarily it is not necessary to use any, and at least not to place one on the bar for each stanchion as shown. As described, the spring maintains the bar or tends to throw it for open positions of thestanchions, means being provided for throwing the same to locking position against the action of the spring and maintain it in locked position.

For throwing the stanehions to closed position, I provide a lever or arm 35, which is connected bylink 31, or the equivalent, to the bar. In the construction shown the link is pivotally secured at 33, to the arm 35 and at 32 to the bar. The: arm 35 is: pivotally supported at 3st to the bracket 36 on the stanchion head- Obviously, an. equivalent construction might be employed for the purpose.

As mostclcarly shown in Figs. 3 and 4:,it will be noted that I' have provided the part 16 with 21, similar to the other part 21'37 being a pin or bolt projecting therethrough. l'Vhen, the latch 24 is thrown over to the dotted position indicated on. the left hand stanchion in Fig. l, the same is arranged to engage with the part 2L orpin 37, and lock the two. stanchion parts 1 and 2 together.

On locking the two together, however, the latch is disengaged from the rod 22,. so that that stanchion or any other one in which the latch is so thrown, will for the time be disengaged from the controlling and. actuating mechanism and be independent from any other one. Any stanchion may in this manner be disconnected from the bar 22, so that when the remaining stanchions are operated the stock retained by the unoperated stanchion will be locked in place. In this manner any one or more stanchions may be thrown out of operation without affecting the operation of the others. It will also be noted by raising the latch 2i, any stanchion may be independently operated without operating any of the others. Consequently any one or more of the stock may be released without releasing the others.

Assuming the stanchions are open, as shown in Fig. 1, when the cattle are all in place, lever 35 may be operated to close the st-anchions, and it willbe noted thatif the lever is thrown, as shown in Fig.3, the pivotal point or center 33 isbelow the center 34; consequently, any pull on the stanchions tending to open the same will be prevented until the lever 35 is raised. However, any addition-a1 locking means may be employed, but when constructed as shownand described the same is ordinarily not necessary. Raising the lever 35 moves the bar 22, and through the latches 24 positively pulls the stanchion parts open, movement of one part through the racks and gears throwing the other part to open position. In case of a single acting stanchion, of course only the movable side would open.

To adjust the stanchion for different sized cattle it is only necessary to adjust the

parts

13 and 14 on the stanchion parts 1 and 2. The stanchion may be constructed so that the bottom may be adjusted by providing the additional holes in the parts 1, through which the pins 3 may pass. It will be noted that with this construction a separate stanchion head is not necessary, as the parts (i and 8 not only form the stall head frame but provide a stanchion support to which the stanchions are directly connected. in setting up the stall fume the partitions 3t), and connecting members shown, or their equivalents, are ordinarily provided.

It may be mentioned that in the drawings I have not considered it necessary to ondeavor to illustrate the parts in their proper relative proportions, as changes in the proportions of the parts would in no wise alioct the operation.

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 I do not wish to be understood as limiting myself to the exact construction, arrangement or combination of parts herein shown and described, or' uses mentioned.
