Patented July 8, 1952 "UNITED STATES 2.-.6oa621 MILKIN'G MACHINE HANG-En Leander F. Fasching, Winsted, Minn.' applicati@ Juneye, 194s, serial :a1-,853 1y claim. (C1. 24a- 285)- The present invention relates to a novel and improved device or hanger for suspended-type milkingV machines, the samebeing such in const'ruction that it is calculated to take the place ofsurcingles such as arecurrently used on a cow being machine milked.

More specifically, the invention has to do with an up-to-date highly practical hanger construction which lends itself to adequate and satisfactory use when adjustably clamped on a fixed portion of a dairy barn stall.

In carrying out the principles of the invention I have found it` expedient and practicable to utilize a vertical member of a dairy barn stall as a suitable place to attach a milking machine hanger. Therefore, it is an object of the invention to provide a simple, reliable and efficient hanger which accommodates the cow and the attendant andwhich takes the form of an attachment which is readily suitable and applicable to the associated parts of the stated stall.v

A further object of the invention is toprovide an attachment-type hanger which is strong, reliable, easy to handle and which adapts? itself to the'various needs of each individual cow.

A further object of the invention is toprovide a hanger'which has facilities whereby it may be regulated in relation to the cow as to height, extended location of the primary machine hanger arm, which allows 'he latter arm to be appropriately tilted or angle for best results, a guard arm being embodied to prevent side movement of the cow during the milking step.

Briefly, the preferred embodiment of the invention is characterized by a U-shaped fixture,

means swingably mounting said fixture on the chosen part of thestall, said fixture including a horizontal limb, a vertical shaft portion and an upper limb, the shaft portion being swingably and adjustably mounted, the first named limb serving to accommodate an extensible and retractable hanger arm and the upper limb serving to accommodate the aforementioned guard.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

'Figure' 'l is a fragmentary elevational view basedv on- Figu'r 1 and vshowingI .the clamping bands, tubular bearing and hanger i'lxturei bodily adjusted from left to right to vary the verticali-ty of the: axis of oscillation ofsaid fixture.; Y

ReferringV now to the: 'drawings by distinguishing reference" numerals and. accompanyingl lead lines and;` with reference-first' toxFigure l, the numeral 5 denotes one ofthe end-frames ofa dairy'v barn stall". including an :upright -6 and an 'L-shaped L portion embodying ra, horizontal limb` 1: and vertical 'limb 8 Vwhich is here usedas a support for the invention. It is to be stated that some stall frames are not necessarily shaped alongthe lines of the one disclosed in Figure l. However, the invention is satisfactorily attachabler to most types. What is more, andas far as-the' invention isf concerned, I am interested only in av fixed support ytot which ther attachment is applicable, for example, the limb or support 8. The invention is characterized by a substantially U-shaped fixture 9 whose central portion constitutes a shaft I0, whose lower arm II projects at an angle in relation to the shaft and support 8 and whose upper arm I2 is somewhat shorter and obliquely disposed. The shaft portion is provided with a shoulder I3 which rests rotatably upon the upper end of a tubular vertically elongated bearing I4. The shaft Ill is rotat- -able in the bearing and the bearing is detachably and adjustably mounted on the support 8. More specifically, the bearing is provided with outstanding screw-threaded studs l5 which pierce apertures in the central portions of duplicate clamping bands I6, said bands being fashioned to rotatably and. slidably embrace the support 8. The band ends are connectedby appropriate to accommodate assembling and clamping nuts I8. The hanger arm is tubular and denoted by the numeral I9 and is telescopically slidable on the limb I I. The left hand end of said arm terminates ina hanger hook 2|] which serves to accommodate a suspension-type milking machine 2|. A sleeve 22 is slidable on the limb I2 and has a set screw 22 for regulation and clamping purposes and the free end of the sleeve is curved and upturned as at 23 enlarged perspective viewshowso that it will swing in the path of the frame member 1. It is obvious that by reason of the clamps I6 the entire hanger may be lifted and lowered in respect to the stall floor, whereby to place the hanger arm I9 and milking machine at the desired level, depending on the height of the cow being milked. By rotating the clamps in respect to each other around the axis of the support 8, the shaft IU may be canted or cocked to an angleto=properly tiltthe limb II and consequently the hanger arm thereon. The guard sleeve 2| may be adjusted according to requirements of the cow and the attendant to limit and prevent side movement of the cow. vThe weight of the milking machine on the telescoping arm' I 9 serves to maintain said arm frictionally in the position to which it is adjusted. The entire.,

hanger, including the parts described, except the bearing I4 and clamps I6 may be swung forward and out of the way, when not in use.

In addition to the above, I desire to point out that the tip 23 ofthe guard arm is curved in amanner shown with a view toward minimizing injury and discomfort to theside of a cow as will be evident from the drawings. Further, and as stated said tip 23 is turned diagonally up to properly coact with the frame structureA 'I thusfpermitting the units to'be parallel with said frame structure when in a forward out-of-use position.

The guard arm also serves as a suitable stop when in the latter position. Further, the tip 23,-nced not necessarily rest against the side ofthecow when the unitis in position foruse. The cow may have up to four to six inches of side movement without ill eilect on the milking unit operation or hanger; Again, as stated the main purpose of the guard arm is to prevent excessiveside movement which might pull the milking machine off the hook 20. All frame members are used in rows andtherefore Vthe frameto the left'side of the cow prevents her-'from veering off to the left Changes in shape, size, materials and rear'- rangement of details and parts maybe resorted to in actual practice, so long as they do not depart from the spirit of the invention'or the scope of the appended claim, as is-well understood. l

Having described the invention, what is claimed as new is:

A cow stall attachment of the class shown and described comprising a tubular bearing adapted for vertical disposition in relation'to a relatively fixed support, said bearing being provided with a pair of integral outstanding screw-threaded studs, a pair of clamping bands having intermediate apertured portions embracing said bearing, said studs' extending athroughgj the" aperturesrin the ba'n'ds and beingprovided 'with assembling nuts connecting the bands with the bearing so that the latter may be firmly but detachably mounted on the stated support, a substantially U-shaped heavy duty Xture adapted to support a weighty suspension-type mechanical milking machine, said xture comprising a shouldered vertical shaft portion mounted for rotation in said bearing with ythe shoulder resting on the bearing and further including a horizontal lower limb and an obliqueangled upper limb, a tubular arm telescopically mounted on said lower limb and terminating 'at` its outer end in a hanger hook, and a guard sleeve slidably and adjustably mounted on the free end portion of 'said upperlimb, the free .end of said guard sleeve being laterally bent and said sleeve being provided with set screw whereby it may be adjustably fastened to said upper limb.
