MPROVEMENT IN MACHINES FOR MEASURING GRAIN.

Specification forming part of Letters Patent No. 39,959, dated September 15, 1863.

To all whom it may concern:

Be itknown that I, CHARLES Boss, Hartland, in the county of Livingston and State of Michigan, have invented a new and improved device for tallying or registering the measures of grain as the latter is drawn from a bin or grain-receptacle 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specificatiomin which- Figure l is a front view of my invention; Fig. 2, a section of the same, taken in the line 00 00 of Fig. 3; and Fig. 3, a side view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in connecting in a novel way the slide which covers the disehargeopening of a bin or gram-receptacle with a ratchet-wh eel,havin g an index attached to it which works over a dial, all the parts being arranged in such a manner that by operating the slide so as to open and close the discharge-aperture, the ratchet-wheel will be turned and the number of measures drawn from the bll indicated by the index on the dial.

To enable those skilled in the art to fully understand and construct my invention,[ will proceed to describe it.

A represents a portion of one sideof a grain bin or receptacle, and B is a slide which is fitted between guides a a, attached to the inner side of the bin A.

G is a discharge-opening made in A, and at such a. position relatively with the slide that the latter may be moved or adjusted so as to cover the former.

D is a metal arm, which is attached vertically to the back part of the slide B. This arm extends upward to the upper surface of the upper guide, a, and has a block, E, at tached to it, the under surface of said block being on the upper surface of the guide a, on which the block is allowed to move freely as the slide B is moved. The upper surface of the block E is of inclined form, and slightly rounded or curved, as shown in Fig. 2.

F is a box, which is attached to the inner side of A, just above the guide a and block 1 E. Within this box F there is placed a ratchet-wheel, G, the front journal, I), of which passes through A and has an index, H, attached to its end. This index works over a circular dial, I, on the front side of A. (See Figs. 1 and 3.)

J is apawl, which is formed of a fiat piece of steel bent in right-angular form. One end of this pawl is secured to the outer side of the box F, as shown at c c, and the opposite end passes through a slot or opening, (I, in the bottom of box F, as shown clearly in Fig. 2. This pawl J is, when not acted upon, kept free from the ratchet wheel G by its own elasticity, and the pawl is directly over the block E and in such a relative position with it that each time the slide B is moved so as to close the discharge-openingG of the bin or grainreceptacle, the block E forces upward the pawl J, and the latter thereby turns the ratchet-wheel G the distance of one tooth, and the index H will be turned the distance of one graduation on the dial I; hence each measure of grain drawn from the bin will be indicated by the index on the dial as the slide B is shoved inward, and the dischargeopening 0 closed each time the measure is filled.

I would remark that the ratchet-wheel Gr may be provided with a holding-pawl, or afriction-plate, K, may be made to bear against itsjournal b, in order to preventthe ratchet from turning during the descent of the pawl.

I am aware that tallying-machines already exist in which ratchet-wheels and indices are employed, and I do not claim the invention of such devices; but,

Having thus described my invention, what Patent, is-

The combination, with the frame A, discharge-opening U, and grain valve or slide B of a grain-bin, of the arm D, inclined block E, actuating-pawl J, and index-box F, containing the indicating mechanism, in the manner and for the purpose herein shown and described.
