DEVECE FOR. PREVENTING: COWS FROM LYING- DOWN.

Application filed February 20, 1322.

To all whom it may concern: 7

Beit known that 1, HARRY lV. Base, a citizen of the United States, residing at New Berlin, in the county of Ghenango and State of New Yorkfhave invented certain new and useful improvements in Devices for Preventing Cows from Lying down, of

' which the following is a specification.

My invention relates to a device, for use in connection with a stanchion to prevent a cow from lying down after being washed or cleaned, preparatory to milking.

An important object of the invention is to provide a device of the above mentioned character adapted to be used in connection with the ordinary stanchion, and which will not be liable to inconvenience or injurethe cow, while standing, and will permit of the ordinary movements of the stanchion, by the cow. 1

A further object of the invention is to provide a device of the above mentioned character, which is readily reversible so that it may extend in either direction.

' A further object; of he invention is to provide adevice of the above mentionedcharacter, so constructed that a plurality of them may be released by the operation of a single lever or the like.

A further object of the invention is to pro vide a device of the above mentioned character, which is simple in construction, cheap to manufacture, strong and durable. I

ther objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation of apparatus embodying my invention,

Fig; 2 is a vertical transverse section, taken on line 2-2 of Fig. 1, looking in the direction of the arrows,

Fig. 3 is a horizontal section taken on line 3'3 of Fig; 1,

Fig. 1 is an enlarged side elevationof the device, showing it in the raised position,

Fig. 5 i a plan view of the same,

Fig. 6 is a side elevation of the vertically adjustable supporting sleeve or element, associated elements being shown in section,

i Fig. 7 is a horizontal section taken on line Z'? of Fig. 6, and, a

Serial 1W0. 538,074.

Fig. 8 is a detail section taken on line 88 of Fig. 6.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a supporting frame, as a whole, including a horizontal bar or tube 11, and vertical posts or tubes 12 connected therewith and supporting the same. Curved laterally extending bars 13 are connected with the bars 12 and extend downwardly for connection with the floor 14-, preferably formed of concrete. The bars 12 divide the structure into a number of stalls 15, as is well lmown.

Arranged at the forward end of the stalls are stanchions 16, which may be of any Well known or preferred type. These stanchions are pivotally supported at their upper ends by links 17, secured to sleeves 18, which in turn are mounted upon the upper tube 11. Chains 19 or other flexible elements serve to connect the lower ends of the stanchions with the floor 1 1.

The device to prevent the cow from lying down comprises an arm or bar 20, which is preferably tubular, and has its free end bent into a curved point or neck 21, so that the cow may not be injured. The inner end of the arm extends into a tubular socket 22, rigidly secured upon a fiat head or disk 23, and preferably formed integral therewith. The head or disk 23 is provided with a central 1 opening 24 (Fig. 7 to pivotally receive a cylindrical extension or trunnion 25, formed upon a head or disk 26. The extension or trunnion 25 has a reduced screw threaded extension 27, forming a shoulder 28. The extension 27 receives a cap or head 29, held thereon by a nut 30. It is thus seen that the shoulder 28 will engage with the head or cap 29, and the head or disk 23 will be free to swing upon its pivot 25.

The head or disk 26, Fig. 6, is provided with a pair of rearwardly extending apertured knuckles or ears 31 and 32, preferably formed integral therewith. These ears or knuckles are arranged within ears or knuckles 33, and the two sets of knuckles are pivotally connected by means of a vertiare ' .position.

it parallel with the stanchion.

justedupon the post 12, and clamped thereto at the desired position.

Surrounding the bolt or pivot element 34, between the ears 81 and 32, is a coil spring 38, one end of which contacts with the clamp or sleeve element 35, and the other end with the head or disk 26, Figs. 6 and 7. The function of this spring is to swing the iead or disk 26 in one direction upon its pivot, for normally retaining the arm 20 substantially parallel with the stanchion 16. The lower ear or knuckle 32 is provided with apair of lateral extensions 39, having screw threaded openings 40. A stop bolt 41 may be adjustably mounted in either of these openings, and carries a lock nut 42. The stop. bolt ll is adapted to engage with either stop lug 43, cast integral with the sleeve element 35. When the arm 20 extends to the left, the spring 38 has its ends engaging the right-hand portions of the sleeve element 35 and head 26, and the stop bolt 41 will then engage the left-hand stop leg 43. If the arm 20 is reversed so that it extends to the right, the spring 38 and stop bolttlare reversed,'so that the spring will then function'to swing the arm 20 and its head 26 in an opposite direction, retaining The stop bolt ll will then engage the stop leg 43, to the right.

In order that the arms 20 may be locked in the horizontal position, their heads or disks 23 are provided with a pair of diametrically oppositely arranged openings or notches 44, adapted to receive reoiprocatory bolts d5, slidable within guides or housings d6, preferably formed inte ral with the ear 31 and head or disk 26, as shown in Fig. 6.

The bolts are provided with slots or recesses 47, receiving screws 48, or like elements. The bolts are provided with shanks 49, and are urged downwardly by springs 50, surrounding the shanks within the housings 4-6. Itis thus seen that when the arm 20 is swung to the horizontal position, that the bolt will automatically enter the opening or notch 44-. and lock the arm in this A pair of notches {M are provided in each disk, so that the notches will function properly when the arms 20 are reversed.

Means are provided to simultaneously op- I erate the several bolts 4-5, including cables ly to the horizontal position.

51, extending upwardly for connection with cranks 52, which are ri idly mounted upon a rock shaft 53. This rock shaft is journaled within stationary bearings 54, and is turned by a lever 55, as shown.

-In operation, after the cows have been washed or cleaned, while standing in the stanchions, the arms 20 are shifted upward- As soon as they assume these positions, the bolts 45 automatically enter the notches 4A, and the arms are thus locked against vertical swinging movement. The arms 20 will prevent the cows from lying down, but does not interfere withthe ordinary movement of the stanchions. A cowfmay shift the stanchion laterally, or turn the same upon its pivot, as shown in Fig. 3, andthis movement of the stanchion will swing the arm 20 forwardly, the same turning upon the pivot 34. By these means anysudden movement or lunge of the cow will not break the stain chion or arm 20 or injure the cow. l/Vhen it is desired to lower the arms, the operator may swing the lever 55 upwardly and all of the bolts 45 will be retracted from the notches 14, and the arms 20 will gravitate to the lowered or vertical position.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:
