HOG SELF-FEEDING MACHINE.

Specification of Letters Patent.

Patented Jan. 28, 1919.

To all whom it may concern:

Be it known that I, THOMAS CARR BRACK- ENBURY, a British subject, and residing at No. 1335 10th avenue west, in the city of Calgary, in the Province of Alberta, in the Dominion of Canada, have invented a new and useful I-Iog Self-Feeding Machine, of which the following is a specification.

This invention relates to improvements in hog self feeding machines of the type having a rotary hopper set above a circular trough, and the objects of the invention are to prevent the feed falling through when the hopper is stationary, to eliminate waste in hog feeding, to eliminate uneasiness and friction among the hogs feeding, to prevent the feed from coagulating or becoming a solid mass, and generally to improve and simplify the construction of the device to cause the various parts thereof to better perform the functions required of them.

The invention consists essentially of the improved construction hereinafter described in detail in the following specification and accompanying drawings forming part of the same.

I attain these objects by the machine or device illustrated in the accompanying drawing, in which Figure 1 is a full exterior view of the hog self feeding machine with cover, and showing hogs feeding; Fig. 2 is a vertical cross section of the entire hog self feeding machine; Fig. 3 is a view of the interior cone with container removed; Fig. 4; is an interior view of the container apart from the cone and trough, showing guide braces; Fig. 5 is a cross section of the ball bearing casting, showing threaded pipe standard, lock nut and chords attached.

Similar numerals refer to similar parts throughout the several views.

The heavy sheet metal cone 1 in Fig. 3 constitutes the bottom or base of the hog self feeding machine and stands at an angle greater than the angle of repose of small chopped grain. The base of the cone 1 is extended out beyond the rim of the container and at the outer edge a flaring flange 2 creates a trough 3, the edge of which flange is curved so as to protect the hogs from injury. The pipe standard 4 threaded at the top rests upon and is made fast to the floor or base of the cone 1 at the point 5 and passes through the apex of the cone at 6. Just above the apex 6 of the cone a heavy plate 7 encircles the pipe standard. To the heavy plate 7 are attached iron bars or guide braces 8 extending to and through the container or hopper and projecting over the edge of the trough at 9.

The purpose of these iron bars or braces is; first, to maintain the container or hopper in alinement with the pipe standard 1; second, as stated above, to loosen the feed and to prevent it from coagulating or becoming a solid mass; third, to provide, through their projecting over the top of the trough, fins or blades which turn and revolve the container or hopper as the hogs push and press against them when feeding. A ball race casting is fitted to the threaded top of the pipe standard. The casting is in two sections. The lower section 10 is threaded; the upper section 11 is not. Attached to the upper section 11 of the ball race casting are the iron chords 12 which extend to the sides of the container or hopper and support it. The upper section 11 of the casting, of course, can revolve freely.

The container or hopper is lowered or raised by turning the lower section 10 of the casting upon the threaded portion of the pipe standard 4;. At the point 13 is a lock nut which looks the lower or threaded section 10 of the casting and prevents it from revolving when the container or hopper is turned in hog feeding. 1a is the container or hopper. -15 is the covering of the container.

I claim:

1. A hog feeder comprising a feed trough, a rotary feed hopper located over the trough and having the lower edge projecting inwardly from the edge of the trough, and a plurality of blades extending through the feed hopper and over the trough.

2. A hog feeder comprising a stationary feeding trough, a cone centrally disposed therein, a standard extending upwardly 100 from the cone having a threaded portion, a two-part ball race mounted on the standard having one-part fixed to the standard and the other part free to rotate, a rotary feeding hopper connected to the part of the 105 ball race which is free to rotate, a plurality of radial blades extending through the feedard, radial blades secured to the plate exing hopper and over the edges of the feedtending through the feeding hopper and ing trough. over the edges of the trough. 1O 3. A hog feeder comprising a feeding Dated at Calgary, Alberta, this 14th day 5 trough, a central standard therein, a feeding of February, 1918.

hopper rotatably mounted on the standard, a plate rotatably mounted on the stand- THOMAS CARR BRAGKENBURY.
