EDWIN BECKVVITH, OF BUTLER, PENNSYLVANIA.

GRASS-MOWER.

SPECIFICATION forming part of Letters Patent No. 255,913, dated April 4, 1882, Application filed December 31, 1881. (No model.)

To all zr/Lom it may concern:

Be it known that I, EDWIN BECKWITH, a. citizen ot' the United States ot' America, residing at Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Grass-Mowers; and I do hereby declare the following to he a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart ot' this specification.

My invention relates to an improvement in grass-mowers; and it consists in two circular horizontal cutting-blades whose faces nearly touch each other, the upper one rotating and the lower one stationary. Both blades are at their cireumferences provided with cuttingteeth, and motion is imparted through any suitable cog and bevel gearing communicating with the driving-wheels ot' the carriage, as will be more fully described hereinafter.

The accompanying drawings represent my invention.

Figure l is a plan view; Fig. 2, a vertical longitudinal section,

and Fig. 3 is an edge view.

A represents the carrier ot the cuttingblades, consisting of a straight piece, a, that terminates at its outer end in a horizontal cirend being attached to the carriage. Under the piece ct there is to be a pivoted wheel for support of the carrier, turning in all directions with the carriage. 0n top ot' the piece a is secured another shorter piece, b, whose outer end, e-a holizontal quadranthas its curved side turned out and backward. The pieces a and bare recessed at their outer ends for the admission between them of two circula-r blades, B B', placed horizontally, their faces nearly in contact. The under one, B, is rigidly secured on the disk d,

whose circumference extends to the teeth on the blades. Both blades are armed with teeth formed to cut in one direction only, and the grass when cut is pushed away from the cutterby theroundedelulcot' thepiece b. Through the center of both blades passes a spindle, c, that is journaled in or passed down through the disk d, and passes out through the corner of the quadrant e, where, by a bevel-wheel and other suitable gearing, it is connected with the carriage driving wheels, which are not here shown, as they-form no part of this invention. The upper blade, B', is fastened to the spindle and revolves in close proximity to the under one, cutting the gra-ss and flinging it backward.

Having thus described my invention, I claim- In a grass-mower, the carrier A, composed of the two pieces t b, the part a having its front end formed into a circular disk, d, which forms a support for the non-rotating blade B, and the part b, having the quadrant c formed upon it, substantially as shown.

In testimony whereof' I affix my signature in presence of two witnesses.

EDWIN BEGKWITH.
