FEED-RE G'ULa ron.

Application filed March 18, 1901. Serial Ito- 363,026.

To all whom it may concern:

Be it known that I, ORVILLE M. .MORSE, acitizen of the United States of America, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain newand useful Improvements in Feed-Regulators, of which the following is a specification, reference being had therein to the accompanying drawings.

It is the object of the invention to obtain a feed mechanism for granular or comminuted material, in which the quantity of material fed in a 'iven interval of time may be regulated to alligh degree of accuracy.

To this end, the invention consists in the construction as hereinafter set forth.

In the drawings, Figure 1 is a perspective a view of one form of the apparatus; Fig. 2 is a vertical section in the plane of the adjustable feed spout; Fig. 3 is a section through a modified form of the apparatus; and Figs. 4 and 5, are diagrammatic sectional views, illustratin the principle underl ing the construction.

ltIy invention is base on the principle that the'angle of the sides of a pile of granular or commin'uted material remains practically constant under uniform conditions. Thus, if the granular or comminuted material is fed on a disk, or flat plate of any kind, so as to cover the entire surface, it will rise in a y ramidal form, the angle of the sides bein determined by the nature of the material employed. ain, if ranular or comminuted-materia is fed tirough an aperture upon a horizontal plate arran ed beneath the same, it will spread OUL at t e base, but on}; to a limited extent.

ased upon the principle as above stated, I have devised aconstruction of feed mechanism. in which the granular or comminuted material is fed over the edge of one plate on to a lower plate, being permitted to assume its natural angle, and the pyramidal pile thus formed is then moved laterally to discharge the same, being immediately replaced b a new supply from the up er plate or is ge. This ma be accomplishe in two ways, illustrated (llagrannnatlcall respectively in Figs. 4 and 5. In Fig. 5, the material A is fed through an a erture B in a plate C upon a lower plate D In Fig. 4 a late E, havin an aperture F, is provided with a superposed guard plate G above the aperture. This guard plate is of suflicientsize to prevent the spreadm of the material when actuated by gravity 9. one so .as to discharge through the aperture F therebeneath. If, however, the pile of material-resting on the 'base E is moved laterally, as by a sweep H, it will be i discharged through t e aperture F at a medetermmed by the s eed of the swee In like manner, a latera movement of t 1e pile U N IT EDiIA ES PATENTOFFICE. i

of material, asshown in Fig. 5, resting upon the plate 'D', will permit a rther discharge of the material through the aperture B, but as soon as lateral movement ceases, further feedin through the aperture B is arrested.-

With either of the devices described, the rate of discharge of the material is a function of the area of the aperture, the height of the space between the up or and lower plates, and the speed of the ateral movement imparted to the material. If these factors remain constant, the rate of discharge is constant, but avariation in one or more of the factors will produce acorresponding variation in the rate of discharge.

The preferred form of the embodiment of my invention is illustrated in Figs. 1 and 2, and is of the following construction: A is a stationary receptacle, or holder, for the su ly of granular or comminuted material.

1s the bottom plate of this receptacle, which is provided at one point, preferably near the periphery, with a discharge aperture C. D is a disk, or revoluble plate, beneath the receptacle A, which is mounted upon a shaft E, and is. driven at a constant rate of speed by suitable mechanism, such as the worm wheel F and the worm G, the latter being on a. shaft H, driven by the pulley I from a suit able source of ower. 0

Depending om the receptacle A, m reg istration with the aperture C, is a dischar e spout J having its discharge end vertically adjustable in relation to the surface of the disk B, preferably by providinga member K charge end K of the s out above the disk. If

the disk is revolve at a constant rate of speed throu h the mechanism described, the material will be fed thereon at a uniform rate, producing a circular column of uniform width and depth. Before the revolution of the disk is completed, this column of granular or comminuted material is deflected laterally over the edge of the disk by a suitable scraper L, which is shown and is provided 1 adapted to support the material fed through with two. scraping blades M and N. 1

has been stated, the spreading of the granular or comminuted material upon the supporting base will be constant under uniform conditions, but will vary to'some exent by variation in pressure. I, therefore, preferably provide a guard plate 0, above Lhedischarge aperture 0 for relieving the material in the spout J from the pressure of 'the weight of the material in the receptacle A; I have further provided a sweep, formed by the radial arms I, mounted upon the shaft E, which extends mto the receptacle A, these arms moving the material laterally to fill the spout J.

' This feed mechanism is capable of extreme nicety of adjustment, as theheight of the extension member K of the discharge s out may be adjusted by screwing it up or own on the threaded member J.

As a modification, the construction illus trated in Fig. 3 may be employed, in which the rate of feed is determined by the rate of travel'of a sweep P Within the rece tacle A. This sweep P moves the 'materia laterally beneath the guard plate 0, which is above the discharge a erture C permitting the dislaced material to fall through said aperture.

e rate of feed may be varied by an adjustable plate R, which increases or diminishes the area of the aperture C. This modification is not as desirable a structure or as accurate in its operation as the one illustrated in Figs. 1 and 2, but, in a broad sense, it embodies the same principle of operation.
