UNITED STATES PATENT OFFICE.

ALBERT MORLOCK, OF BROOKLYN, NEW YORK, ASSIGNOR TO JAMES S. SIMPSON AND GEORGE F. SlMPSON, BOTH OF SAME PLACE.

GRINDlNC OR PULVERIZING MILL.

SPECIFICATION forming part of Letters Patent No. 373,190, dated November 15, 1887.

Application filed February 4, 1887. Serial No. 226,537. (No model.)

To all whom it may concern..-

Beit known that I, ALBERT MoRLocK, of Brooklyn, Kings county, and State of New York, have invented a certain new'and useful Improvement in Feeding Mechanism for Grinding and Pulverizing Mills, of which the following is a specification.

I will describe my improvement in detail, and then point out the various features in the claims.

In the accompanying drawings, Figure 1 is a side elevation of the mill, with some of the parts in section and others broken away, embodying my improvement. Fig. 2 is a rear elevation of the same.

Similar letters of reference designate corresponding parts in bot-h figures.

The mill in connection with which I have shown my present improved feeder embodied, is known as an eccentric mill, but it Vmay be of any desired or suitable construction.

My present improvement relates particularly to the means for feeding materialinto a chamber. A, containing mill plates.

D designates a chute, which is of concavoconvex form, tilted downwardly at the 'forward end, which projects over a collar, C, on the upper mill-plate. The chute is hung at the rear end upon a pivot-pin, d, extending from the basesection of a feed-hopper, E, and is supported at its forward end upon a pin, d', which is affixed to a lever, G. This pin will preferably be made in the 'form of a screw, and pass through a screw-threaded hole in the lever, and may be provided with ajam-nut, sol

-t-hat the pin may-be elevated or lowered to ferent positions by means of aset-scrcw. This arm I is acted upon by a cam or eccentric, B, which is mounted upon the main shaft B of the mill, so as to rotate with the latter. The upper part of this lever has connected to it one end ofaspring, J,wh0se other end is connected to a screw, K, which latter extends through a standard, L, mounted on the mill-frame. A nut applied to this screw provides for adjusting the same lengthwise to vary the tension of the spring. The springJ vibrates the lever in one direction and the cam B vibrates the le ver in the other direction.

By adjusting the arm at different angles to the lever G the throw ofthe lever may be varied, because as the lever is moved nearer to or farther from the shaft B it will be acted upon more or less by the cam B', whereby the rocking motion of the lever G will be augmented or increased. By this means the de-v gree of vibration of the chute D can be varied as desired, so as to regulate the feed to the mill.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a mill, the combination, with a vertical main shaft, of a cam mounted on said shaft, a rocking lever, an adjustable arm on said le- Ver near its lower end extending into a position to be operated upon by said cam, and a chute connected to said arm and vibrate thereby, substantially as specified. 1

2. In a mill, the combination, with a vertical main shaft, of a cam mounted thereon, a rocking lever, an adjustable arm on said lever extending into a position to be operated upon by said ca m to rock the lever in one direction, a spring for rocking the lever in the other direction, and a chute connected with said lever and vibrated thereby, substantially as specified.
