TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES C. WALKER, of Waco Village, in the county oi McLennan, and. State of Texas, hitveinvented a. new and improved Grain-Meter; and I do hereby declare the following to bee. full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specificatiovi, and in which- Figure 1 is a. vertical section of my invention.

Figure 2 is a. front elevation of the some.

Figure 3 is 'a cross-section of the tube A.

Similar letters of reference indicate corresponding partsin the several figures.

In this invention-the grain is poured into n circular chute, where, in'felling, it rotates a wheel, the revolutions of which, recorded by an indicator, mark the quantity of grain.

In order that others skilled in the art to which my invention eppertnins may be enabled to make and use .the same, I will proceed to describe it in detail.

In the drawings, A represents an annular chute, through which the grain is poured from the receiving pipe a to a, the discharge-port. Within this chute move the buckets b b of a wheel B, the'wheel-shuft being shown at Bnnd the spokes at b b. The spokes are provided with a. guard or rim, Bf", fitting closely to the inner Wall of the chute, and filling the slot 2 in order to prevent the escape of the grain. G is a brush attached to the wallof the chute A, where expands to receive the lower extremity of the supply pipe a, and operalting against the revolviug buc'kets 66, its office being to clean them and prevert the lodging of any kernels between 'the buckets and the walls of the chute. An indieatingapparutus, G, is connected with and operated by the revolving shaft 13, and marks accurately the quantity'of groin passed through the shute.

Iu eonstructing this meter the buckets b 6 should be made to fit closely and yet move freely :inthe chute 'A. The brush C is so fixed to the wall of the chute as to be eusily detachable at any time. To effect this a.

portion, D, of the wall of the tube at that point may be made detitchuble, and provided with holes in which the bristles may be fastened so as to project into the chute, as shown in the drawings. When in use the instrument is intended to be placed so that the line-I on-the dial shall be in a vertical position. A spirit-level, L, may be attached, if desired, in order to'uid in ascertaining the proper position of the instrument.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The combination and arrangement of the wheel B, annular chute A, and brush 0, in a. grain-meter, substantiully as and for the purpose specified. i i

I To the above specification of my improvement I have signed my hztnd' this 1 1th day of July, 1867.

JAS. 0. WALKER.
