MILTON M. MIKAN, OF DURAND, MICHIGAN.

oATTLE-sTAivcnIoN.

To all whom it may concern: 1

Be it known that 'l, MILTON MIKAN, a citizen'of the United States, residmg, at Durand, in the county of Shiawassee and State of Michigan, have invented new and use- .ful Improvements in Cattle-Stanchions, of

. which the following is a specification.

This invention relates to ini'pro'vements in cattle stanchions and meansfor locking and releasing the same the inventionrconsisting in the construction, combination and arrangement of devices hereinafter described and claimed. 7

- One object of my invention is to provide improved means for simultaneously locking or releasing either one of anumber of stanchions, and thereby avoid the necessity :of go-.'

7 ing into the separate cattle stalls forlocking or unlocking thestanchions thereof 'Another object is to pr0v1de means for disconnecting the stanchlon locking and unlocking devices from the common actuating rod to enable any desired stanchionor'stan- I chion's to remain inoperative when the iothers .25

are locked or released.

-;In the accompanying drawings: Figure l is aside elevation of a cattle stanchion and locking and releasing means therefor constructedin accordance with my invention and showing the stanchions in locked posi- I 'tions. Fig. 2 is a detail elevation on a larger scale of one of the stanchions and its locking and releasing means, showing the stanchion in open position. Fig. 3 is a detail'horizontal sectional view ona plane indicated-bythe line aa ofFig. 1. Figs. 4: and 5 are detail views; Fig. 6 is a detail perspective view of the catch for locking the bars in closed position. Fig. 7 'is a detail perspective of the mechanism for preventing movement of the rod.

My improved cattle stanchion locking and.

releasing mechanism is adapted for operaone or any desired tion in connection with number of stanchions. Each stanchion 1 is provided with vertically. arranged pivots 23 at its upper and lower ends which are mounted in pivot bearings in a plateor other elevated device 4 and in a sill or other base support 5; The lower pivot 3 is' provided with a stop 6 which may be of any suitable construction and which coacts with a fixed stop 7 to limit the movement of'the stanchion so that the latter canonly turn through about one fourth of a. circle. On one side of the stanchion is a movablecbar-s Specification of Letters Patent. Patented pl 23, 1916 Application filed'November 6, 1914. Serial No. 870,673. l

which is hinged or pivotally mounted at its lower end as at 9 and is adapted, at its upper end, to close against the head 10. of the stanchion as at 11. The stanchionhead has a shoulder 12 and the bar 8 carries a pivotallyinounted catch 13 which is adapted toengage the shoulder 12 to lock the bar 8 in closed position. Said bar is also provided with a spring 1 1 to snap the catch 13 into engagement with the shoulder 14 when the bar closes. The said catch is provided at its engaging end with a semi-circular arm 15 for a purpose prescntly'described.

A common operating rod 16 for the re'-' leasing and locking devices of all the stanchionsis mounted for longltudinal moveni'enton standards 17 which are here .shown asoarranged on the plate 1:, these stanchions being preferably provided with rollers 18.

which bear against said operating rod and lessen friction. A spring 19 is connected to,

one end.of therod16 to move the latter in .one' direction. A chain 20 is attached to the aclutch element 25 on one side which may be engaged with or disconnected from the clutch element 23 to lock said wheel 22 to the wheel 21 or release it therefrom. A shifting lever 26 is provided to thus lockor release the wheel 24. An operating chain 27. is engaged with the wheel 24 and is adapted to be manually operated to coact with said wheel to cause the wheel 21 to be turned therewith when-the wheel 24: is in clutched position. l/Vhen the wheel 24 is clutched to the wheel 21 and is turned in one direction by the chain 27 the operating rod 16 is caused to move longitudinally in one direction against the tension of the spring 19, to'

Said 'sprin'gs yield to the swinging'move ment of the stanchion occasioned byrtlie' movements of the animal but tendto keeps the stanchion parallel or approximately so with the operating rod 16 to facilitate the movement and operation of the levers 30. In connection with eaoh,s'tanchion I"a1so provide a catch releasing lever 37 which i is fulcruined at 38 and the lower end of which is arranged above thestanchion and slot the block islocked to the rod 16 for movement therewith;
