FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 400,720, dated April 2, 1889.

Application filed October 20, 1888.

To all whom it may concern:

Be it known that I, JOHN B. WHEATLEY, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful lmprovement in Feed-Regulators, of which the following is a specification.

This invention relates more particularly to an improvement in the feed-hoppers of roller or grinding mills, and has for its object to provide means whereby the material in the hopper is prevented from overflowing the hopper or clogging the feed-spout in case the material is fed in excessive quantities to the hopper.

The invention consists of an overflow-passagecommunicating with the upper end of the feed-hopper and Aa distributing device whereby the Vmaterial is allowed to escape from the hopper when it rises to a certain height and is uniformly distributed in the overflow-passage.

In the accompanying drawings, Figure l is a vertical cross-section of a feed-hopper provided with m`y improvement. Fig. 2 is a vertical longitudinal section thereof in line c Fig. l. Fig. 3 is a horizontal section of the hopper.

Like letters of reference refer to like parts in the several figures.

A represents the inclosing-casin g of a rollermill, B the feed hopper surmounting the same, and b the discharge-opening at the lower end of the hopper.

c is a feed-roller arranged in the dischargeopening b, and d an adjustable gate whereby the feed is regulated.

E represents an overflow-passage arranged on one side of the feed-hopper B and extending from the upper portion of the hopper to the lower end thereof. The passage E is preferably formed by a partition, e, arranged within the hopper parallel with the adjacent side wall thereof, and the passage communicates with the feed-hopper by means of au opening, f, arranged in saidpartition near the upper end thereof and extending across the entire width of the hopper. The lower end of the overflow-passage E is o pen and terminates within the casing A at or near the dischargeopening-b of the hopper.

F represents a distributing device arranged Serial No. 288,635. (No model.)l

in the overfiow-openingf, and consisting, preferably, of a revolving roller, as shown. This roller serves to distribute the material as it flows through the opening f and delivers the same upon the grinding-roller below in a uniform stream.

Should an excessive quantity of material be accidentally fed into the hopper B by opening the slide in the feed-spout to an undue extent or from some other cause, the material' will rise in the hopper until it reaches the overflow opening f, when it will escape through said opening into the passage E and pass from the latter into the casingA upon the grinding-rollers.

By providing a distributing-roller in the overflow opening f the material passing through this opening is delivered to the grinding-rollers in uniform sheets in the same manner as at the discharge-opening b Yof the h opper, thereby effecting an even grinding of the material iiowing through the passage E.

The distributing-roller F is driven from the feed-roller c by a belt running around pulleys mounted on said rollers or by other means.

I claim as my inventiou l. The combination, with the feed-hopper provided with a discharge-opening, of a partition forming an overflow-passage communieating with the upper end of the feed-hopper and a distributing-roller whereby the material is uniformly discharged from the upper end of the feed-hopper into the overflow-passage, substantially as set forth.

2. The combination, with a feed-hopper provided with a discharge-opening, of a partition arranged within the hopper and forming an overflow-passage on one side of the hopper, an opening arranged near the upper end of said partition between the hopper and overflow-passage, and a distributing device arranged in said opening, substantially as set forth.

Witness my hand this 28th day of September, Isss.

JOHN Bv. VHEATLEY.
