UNITED STATES PATENT Ormeac HENRY E. DOUGLASS, OF NEW BRIGHTON, PENNSYLVANIA.

IMPROVEMENT IN GRAIN-TOLLERS.

Specification forming part of Letters Patent No. 223,034, dated December 30, 1879 application filed October 2, 1879.

To all whom 'it may concern:

y Beit known that I, HENRY E. DOUGLAss, of New Brighton, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Telling Grain 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it pertains to make and use it, reference being had to the accomv panyin g drawin gs,vvhich form part of this specitcation.

My invention relates to an improvement in devices for automatically tolling grain, or separating from the bulk of grain a certain portion, as is customary at mills, in payment for the grinding; and it consists in a rotary hopper provided with a spout, from which, when rotating, a required fractional quantity of grain falls at every revolution into a stationary compartment proportioned to the quantity of grain to be taken oft', while the remaining portion falls into other compartments and is separated from the former, as vill be fully described hereinafter.

The accompanying dra-Wings represent my invention.

Figure lis a vertical section of my invention. Fig. 2 is a plan view of the same.

In the frame A is supported an open cylinder, B, the closed bottom of which is cut obliquely. Within the cylinder is a circular horizontal frame, O, resembling a Wheel, its diameter being that of the inside of the cylinder. Instead of having spokes at regular intervals, like a Wheel, the circular frame is divided into compartments D, of unequal dime11sions,\vl ich compartments bear certain relations to the surface of the frame C. If, for instance, the surface of one compartment occupies one-seventh part of the Whole surface ofthe frame, the remaining part Would be six-sevenths, (-25) and, when rotating, the one-seventh of the grain falling from the spenta would enter the compartment of that size, While the remainder drops into the others. y l

The frame O being open, the grain passes freely through it to the inclined bottom, at the lowest part of which is an opening, a', from which it may be led to any convenient place.

Attached to the inside of the cylinder, under and in contact with the frame O, is a spout, E, of the form of the compartments D, which spout passes through the slanting bottom of the cylinder; hence all the grain dropped into any one of the compartments placed over this spout becomes separated from the rest.

The frame O, being movable, may be so adjusted that either one of the various compartments occupies the space over the spout E; consequently any desired fractional part of the whole into which the frame C is divided may be taken from the bulk of the grain dropped into the hopper while rotating.

The hopper H is placed upon a vertical rod, b-that is, passing through the center of the fra-me O downward-and is pivoted upon the frame A. The hopper is of the form of a funnel, to which a spout7 n, is attached in a position to discharge the grain continuously into the compartments, and is rotated by means of a pulley, d, on the lower part of the rod b.

Having thus described my invention, I claim- The rotating hopper H, spout u, rod b, and pulley d, in combination with the stationary frame O, arranged substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 23d day of September, 1879.

p HENRY E. DOUGLASS.
