April 28, 1877.

To all whom it may concern:

Be it known that I, EDWIN A. MARTIN, of Thornville,in the county of Perry and in the State of Ohio, have invented certain new and useful Improvements in Grain-Sacking Scales and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement ofa grain-sacking scale, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure l is a side elevation, gitudinal vertical section, of

A represents the box to W ing parts are attached. opening, 13, at the top, grain is poured in, and box divides into two inc with openings at a at the end of the box.

The mechanisms attached to the box are precisely the sam and hence a description of for both.

There is, however, oted in the sides of mouth B, which from side to side, alternately nals of thi and Fig. 2 a lonmy invention. hich all the work-- i This box has an through which the below the same the lined passages, G G, bottom-one at each the ends of e at both ends, one will answer a valve or gate, D, pivthe box A, below the valve is to be thrown over to direct the flow of grain into the passages O G. Thejours valve project through the sides of the box, and upon each one is secured a lever, D, having both ends pointed, as shown.

At the end of the box A is secured a frame, E, and in the same upon suitable knife-edges is hung a cross-bar, G.

From the center of this crossforward a beam, G end, and a hook, I, su one end of the bar G backward along on this scale-beami bar extends having poise H on its spended from it. From G extends a scale-beam, the side of the box, and s an adjustable Weight,

arms, I) and b exte by means of or recess in raised, said gate w right-hand of said lever or a suitable such weight.

At that end of th I raised, and the sack to be suspended fr manner that Now,

At the same the rod d manner. removed, an gate J raised weight D what I claim Letters 1. The com substantially 2. The com dated July 31, 1877; application filed It is, however, evident t maybe used insteadof From the cross bar nds upward into-asl The valve or gate D bein shown in Fig.
