KENNEDY DOUGAN, OF MINNEAPOLIS, MINNESOTA.

FEED-REGULATOR.

Specification of Letters Patent.

Patented July 4, 1911.

Application filed July 19, 1907. Serial No. 384,588.

To all whom it may concern:

Be it known that I, KENNEDY DOUGAN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Improvement in Feed-Regulators, of which the following is a specification.

This invention relates to feed regulators or governors, and has for its general object to provide a machine that will feed in a continuous unbroken uniform stream, any predetermined number of units of a fluid, such as grain or water, per unit of time, and, in the case of wheat, regardless of the conditions of the wheat relative to' its specific gravity, roughness, size, or state of dampness.

A special object of the invention is to provide a feed governor in which the throat and receiver cannot become clogged by the lodgment of straws, etc., contained in the grain being operated on.

The features of novelty are pointed out in the appended claims.

A preferred embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a side elevation, partly in section; Fig. 2 is a vertical section viewed on line 12-00 of Fig. 1, parts of the casing being broken away; Fig. 3 is a plan of the valve frame, detached; Fig. 4 represents a modified counterweight structure; and Fig. 5 is a detail of the receiver.

The body of the machine comprises the receiving chamber 1, a casing forming the throat 2, having the enlarged lower portion 3, and brackets referred to below. Further the machine comprises a valve or gate 4:, mounted on two horizontally disposed arms 5; a pair of depending rods 6 pivotally connected to said arms; and an impact receiving device 7, hereinafter termed the receiver.

The receiving chamber 1 communicates with the upper end of the throat 2 by an opening 8. The valve or gate 4: is set close to but not in contact with the wall of said opening and is of substantially the same size as the opening. The valve is carried by arms 9, branching from the arms 5, which latter are provided with knife pivots 10 resting upon brackets 11 secured to the easing of the throat.

Preferably the valve 1 is curved as shown, to the arc of a cylinder whose center is the pivotal aXis of the arms 5. Said arms are rigidly connected by a yoke-bar 12 to which is secured the graduated beam 13 provided with a fixed weight 1 1 and an adjustable weight 15. Depending from the respective arms 5 and pivoted thereto at 16, are two rods or links, 6 which carry at their lower ends the receiver, 7. Openings for said links are provided in the enlarged base 3. The receiver 7 as shown is in the form of a four sided tube disposed horizontally with its opposed upper faces 7 inclined outward and downward.

The links 6 are secured to the ends of this receiver, and are guided by parallel arms 17 which are set parallel to the valve arms 5. By this device, the receiver 7 will always present the same angle to a vertical plane, 1n any position which it may assume vertically considered. This feature is important, as feed governors having receivers that vary their angle to the stream of material falling upon them are inaccurate, and therefore do not fulfil their purpose.

The receiver is provided with an opening 18 for the reception of shot to be employed for proportioning the weight of the receiver to that of the arm 13, weight 14, etc. Said opening may be made in one end of the re ceivcr if preferred.

The lower two plates 7 of the receiver are not essential to the operation of the stream upon the receiver, but are provided merely to form a receptacle for the shot. When the governor is in use the opening 18 is closed with a plug as 18 seen in Fig. 5.

The beam 513 is provided with a compensating weight 19, set upon an inclined rod 20. By properly adjusting this weight 19 at the factory, the uniform regulation of wet and dry grains will be assured. That is to say: by adjusting said weight to a certain point on its beam, (which adjustment is made at the factory) the governor will be caused to feed the same number of units of grain per unit of time, regardless of the speis filled with glycerin or the like.

cific gravity, dampness or dryness, smoothness or roughness, of the grain. The weight of the compensating weight 19 is to be made about equal to the average impact force of the grain upon the receiver 7 which force is only about a quarter of one ounce produced by a stream of wheat falling at the rate of 10 bushels per hour.

To prevent the inertia of the'movable parts (when in operation) from carrying them too far in either direction, a retarding device or dashpot 22 is employed; its pistonrod 23 being pivotally connected at 24 to a bracket'25 on one of the links 6. The pot 22 'lhereceiving chamber 1 may be provided with manually operated cutoff slides 21, by which the width of the stream flowing through the opening 8 may be varied to that found to be most practical. A closing movement of the slides is followed by decreased impact upon the receiver, ascent of.

the gate 4, and such increase of depth of the stream as will maintain the previous rate of flow.

r Fig. 4 shows a modified arrangement of the graduated beam that is especially desirable in larger sizes of feed governors. Its

purpose is to obviate an inconveniently long beam as 13, projecting outward beyond the body of the machine as in Fig. 1. The

arms 5 are extended to unequal lengths, forming arms 26 and 27, between which the beam 28 is disposed horizontally. It is obvious that as the weight 29 is moved along upon the beam it will either approach or recede from the pivotal axis of the yoke, the effect being the same as that of the weight 15 in Fig. 1.

The operation is as follows: The weight 15 is moved to the left to the limit of its movement and secured there by its thumb .tween the striking force of the grain upon the receiver, and the weights 15 and 19,

as the instant the striking force becomes heavier the gate 4 will be closed partly down, and the instant it becomes lighter the gate will be raised by the weight.

I claim'as my invention:
