"" YELQ ETE v MA H NEUMANNL'OF b w I NE TA wo n-o CALIF EED Be it known that I, Mi- 'r-H NEUMANN, a .citizen of the United States, residing at St. Cloud, "in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Automatic Calf- Feeders; and I do hereby declare the following to be a :fullfcleajr, and exact description of the invention, such as will enable others, skilled in the art to which it appertains to make and use the same. My present invention relates to automatic calf feeders of the type disclosed f'a'nd broadly claimed in" my two United States Patents, #1,276,946,' issued August 27, 1918, and #1,325,035,issued- December 6, 1915). I To the above end, the-[inventionconsists of the novel devices and combinations of devices hereinafter described and defined'in the claims.- p i I In the accompanyingdrawings, which illustrate the invention, like characters'in'dicate like parts throughout the several views.

by the posts'8, and constitute a part ofthe frame, The rails1 0 are rearwardlyinclined, and mounted thereon is a pair of wheelequipped travellers 1.2, Whilethe lower rails 11 are horizontal and have thereon a pair of sliding travellers 13. These travellers 12 and 13 are connectedoneach side of the frame, for simultaneous travelling movement on the respective rails,v by endless sprocket chains 14, in which said travellers are interposed." Both chains 14 are driven from an upper,shaft ljournaled in the rear post 8 above the. upper rails 10, and 'have secured thereto, between the members ofsaid wa snteek whe -16 whieea n d MeY O, 19212. pp i t fi A s ,1920.

J A milk-holding'trough 45 is carried by thefsupplemental frame 24, at the back thereof, andpriovided at its bottom with discharge spouts 46 arranged to delivermilk from said trough into [the pails 29. Normally, the spouts 46 are closed by valves 47 having yoke-like stems48, the armsof which are mounted in guides 49, on the trough 45, and, arranged to be engaged by trips 50 formed by extending therear arms of the secondary scale beams 26. v In the bottom of the trough 45 is a normally closed drain 51, under which is, located a discharge spout 52 secured to said trough. v

v A feed trough 53, for meal or other dry food, is carried by the travellers 13 and provided at its ends with trunnions 54 journaled in the notched disks 23 and travellers 13. This trough 53 is held in differentoscillated positions by means of a sliding latch 55 mounted in keepers on'the travellers 13 for .co-operation with the notched disks 23. These latches-55 are simultaneously operated by fingers 56, which are flexibly interlocked therewith, and carried by a rock shaft 57 journaled in bearings on said travellers 13. The'rockshaft 57 is provided witha the; supplemental frame into a position to' hand piece 58, by which it may be operated.

v Operation.

' Thev operation of the above described inventlon'may be briefly described as follows: Before feeding takes place, the pails 29 are outof the pail holders 27, and the supplemental frame 24 and trough 53 are in inverted posltions. The operator first turns bring the pail holders intoan upright p0sition. The pails 29 are then placed therein and the poises 33 shifted on the primary 1' tendant may operate thecrank 19 to so position said frame and thereby carry the pails 29, out-of reach of the calves, while said pails are being filled. The attendant may sup- 7 milk to flow into said pails.

then pour milk into the trough 45 and part thereof will flow through the open spouts 46 and into the pails 29.

Under the increasing load of milk in the pails 29, the action of the poises 33 is overcome and the primary scale beams 30 raised.

During the raising movement of the primary scale beams 30, the free ends thereof cam the lock plates 39 outward until they come into registration with the apertures in said lock plates. Said lock plates 39 are then free to swing, under the action ofgravity, into positions to cause the free ends of the priinary scale beams 30 to enter-the apertures therein and thereby automatically lock the said s ale beams against return movement.

The purpose of thus locking the primary scalebeams 30 is to preventthe pails 29 from rising as the weight of the milk is decreased by the calves drinking from said pails,and thereby cause the trips 50 to again openthe valves 47 and allow an, additional supply of After the pails 29 are filled with the milk and further supply thereto cut off by the valves 47, the attendant may operate the .crank '19 to lower the supplemental frame 24 and thereby bring the pails within reach of the calves. 'l his,lowering movement of the supplemental fram'e 24-w1ll, of course, impart a rearward travelling movement to the trough 53, so that it is out of the way. When the pails 29 arein their lowermost positions, the weight thereof comes directly on the supplemental frame 24, through the fingers 28, and thereby .affords a firm support for the pails whilethe calves are drinking.

In case it is desired; to one ofthe valves 47 may be kept closedby lifting the respective primary scale beam 30 and securing the same in a raised position by allowing its lock plate 39 to drop into interlocking engagement therewith. 'While onl two pails are shown, it is, of course, understood that the apparatus may be of such size as to hold any desired numberof pails.

.Meal or other dry food to be fed to the calves, may be placed in the trough 53, and i the crank 19 operated to cause the travellers 12 to move rearward, thereby lifting the pails 29 out of the way and causing the fill only one: pail,

travellers 13 tomove forward and position A the trough at the front of the apparatus,

When the calfxfeeder is not in use, the

pails 29 may be removed from their holders 9 interlocking .the same. therewith tohold said troughs in their emptying positions. "When:

the troughs 45v and 53 are in their emptying positions, they maybe easily cleaned and left in this positionuntil the next feeding time,

thus preventing dirt from settling therein. Any milk remaining in the trough 45 may be removed therefrom, before said trough is turned into an emptying position, by open ing the drain 51 to permit the milk to run into the spout 52, Where it may be caught.
