SPECIFICATION forming part of Letters Patent No. 227,409, dated May 11, 1880,

Application filed March 18, 1880. (No model.)

To all whom at may concern:

Be it known that I, RoLLIN G. BROWN, of De Witt, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Grain-Tallies; andIdo 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 accompanying drawings, which form part of this specification.

My invention relates to an improvement in grain tallies and it consists in a revolving tray which is divided into compartments or divisions, and which has a cam formed on its outer edge, corresponding to each one of the divisions of the tray, and which cams, as the tray revolves, serve to operate the counting mechanism.

It further consists in forming upon one side of the counting-wheels a projection to catch in the teeth of a pinion, which pinion is sufficiently wide to overlap and mesh with the adjoining wheel, whereby it is made to perform a double function, as will be more fully described hereinafter.

The object of my invention is to provide a tally in the measuring of grain which shall operate all the same whether the tray is turned to the right or to the left, and which shall be cheap and simple in construction, and always reliable in operation.

Figure 1 is a plan view of my invention with the front of the counting mechanism removed. Fig. 2 is a side elevation of the same, partly in section.

A represents a revolving tray which is divided into three or more compartments, B. In each one of these compartments a measure is placed, which is to be filled by the grain, and as one measure is filled from the hopper or spout the tray revolved so as to bring another one unde On the outer edge or circumference of s tally there are formed a number of cams,G, which correspond in number to the divisions B, and which cams serve to operate the pivoted lever D, which projects from the side of the box IE, containing the counting mechanism. The outer end of this lever is provided with a friction-roller, and

catches in the cams formed in the side of the tray, so that as the tray is revolved the lever is given a reciprocating motion on its pivot. Secured to this lever, inside of the box, is a suitable spring, which holds the end of thelever pressed constantly downward, so that after it has been released from the end of one cam it will be held in position to enter the end of the next succeeding cam, no matter in which direction the tray may be turned. The inner end of this lever is formed like an escapement, and serves to turn the wheel I forward just one cog every time the lever is operated by one of the cams. IV here itis intended to count bushels this wheel will be provided with but ten teeth; but where half-bushels are to be counted the wheel will be provided with twenty cogs, as in the present instance. On the inner side of this wheel there is formedaprojection or tongue, 0, which, as the wheel sweeps around, catches in the teeth of the pinion N, and for ever 7 revolution of this wheel I the pinion is moved just one tooth. This pinion is made sufficiently wide so as to mesh with the second counting wheel, R, which is provided with teeth on its edge, as shown, and which pinion, as it is moved forward one tooth at every revolution of the wheel I, moves the wheel It forward one tooth also. This same construction is continued on all of the other wheels of the counting mechanism, each one of the countingwheels being provided with teeth to mesh with the pinion, and a projection to turn the pinion one tooth forward at every revolution. These wheels, of course, represent tens, hundreds, thousands, and tens of thousands, and can be increased to any desired number.

The counting-wheels are all placed side by side upon a single pivot, and the pinions are placed upon a second pivot, which extends parallel therewith.

B y thus making the pinions sufficiently wide to be operated by one wheel and to operate a second wheel at the same time, the number of parts are greatly reduced and the cost of the mechanism cheapened accordingly.

Having thus described my invention, I clai1n l. The combination of a revolving tray divided into compartments B, and having cams 0 formed upon its outer edge, there being one tray is turned to the right or left substantially 1o cam for each one of the compartments, with a as described.
