JONAS D. HENRY AND WILLIAM E. \VOOD, OF PORTLAND, OREGON.

FEED-MILL.

SPECIFICATION forming part of Letters Patent No. 449,445, dated March 31, 1891.

Application filed January 27, 1890. Serial No. 338,319- (No model.)

To (0% whom, it may concern:

Be it known that we, JONAS D. HENRY and WILLIAM E. W001), citizens of the United States, residing at the city of Portland, lil ultnomah county, in the State of Oregon, have invented a new and useful Improvement in Feed-Mills, of which the followingis a specification.

Our invention relates to improvements in feed-mills, the object of which is to improve and simplify the feeding mechanism for urging and discharging the feed into the mill, combined with handy means for regulating the discharge of such feed intothe mill. This we believe to accomplish in a better and more perfect manner by the means illustrated in the accompanying drawings, forming a part hereof.

In the drawings, Figure l is a side elevation. Fig. 2 is an end view of the hopper, showing the gateadjusting mechanism. Fig. 3 is a perspective view of the hopper and shoe with parts broken away. Fig. 4c isa perspective View showing the manner of operating the pitman-rod, and Fig. 5 is a top view of the mill with parts broken away.

Like letters refer to like parts.

The inclined vibrating shoe A is hung from two upper i and two lower t" springs, which springs we prefer to construct of wood, but may be constructed of any other suitable material. The attachment of the springst' to the standards D D and frame of the shoe and of the springs i to the end of the shoe and the supporting'frame E is a mode we have found most convenient as well as serviceable, enabling the several parts of the mill to be located in their proper place for giving the same a large vorking capacity. The pitman-rod Z, operating the shoe A, is given the shape shown in the drawings, being made quite thin at 76, so that it will yield to the vibrations of the shoe without danger of breaking, and the means of operating the same is seen in Fig. l, its end is being attached to a cross-board under the frame of the shoe, and its eccentric set on the shaft carrying the pulley m, the pitman being held in place on the eccentric by means of two strips of metal Z. The throw of the pitmanrod should be about half an inch. The feeding device, however, constitutes the main feature of our invention, and consists of a bottomless hopper against the open base of which slides an inclined board or feeder a, carried by and oscillating with the vibrating shoe A, and in so doing impelling the feed into the shoe, such feed being discharged through an opening in the inrter end of the hopper, the quantity of the discharge being regulated by means of an adjustable sliding gate Z), operated by means of a lever 0, connected with such gate by an arm f, passing through a slot cut in said end of the hopper, the lever 0, when adjusted, being held in place by being pressed against the rack O by the spring h. h is a strip of metal for such spring h to slide on. The space in which this gate 1) slides is covered by a sheet of metal 6 to prevent feed from getting into it.

The pulley m, operating the pitman, is run by a belt from a counter-pulley it, set on the shaft of the pulley n, to which the power for operating the mill is transmitted.

In the housing 7" r are two crushers or rolls 0 0, their journals revolving in the bearings of the saddles p p, the roll 0 operating the roll 0 by friction and the bearing of the latter on the former being adjustable by means of set-screws q. The feed to be crushed being inserted in the hopper,it is discharged in desired quantity into the shoe A and thence carried to the rolls or crushers o 0, passing in its course through a sieve s, and the crushed feed being emptied into a convenient receptacle by means of the elevator F, which is run from the pulley m.

Now what we claim as our invention, and desire to secure by Letters Patent, is-

In a feed-mill, the combination of the hopper, the adjustable sliding gate b, and the adusting mechanism therefor, consisting of the rack O, lever 0, provided with a spring h, pressing it against such rack, and arm f, by which said lever is attached to the gate, the hopper being supported over an inclined vibrating board a on the shoe A, which coacts therewith and constitutes its bottom, all as herein substantially described.
