Definitions
- This invention relates to-a new and improved device for mowing grass by hand, and is more especially designed for mowing lawns.
- the invention consists in a novel manner of constructing the frameof the machine, and mounting it on a roller, whereby the latter is made to have sufiicient traction to drive, in the most eflicient manner, the cutting-device.
- the invention also consists in a novel manner of applying the handle to the frame of the machine,
- the invention also consists in a novel and improved cutting-device, which may be constructed at a very small cost, and still be; strong, durable, and notliable to 8 ring during the operation of cutting.
- he invention further consists in a peculiar application of shoes to the device, whereby the height of the out may be regulated as desired. 7
- Figure 1 is a side sectional view of my invention, taken in the line a: as, fig. 2.
- Figure 3 a side view of oneof the shoes pertaining to the same, and a portion of the framing to which the shoe is attached.
- the frame of'the machine is composed of two sidepieces, B B, connected, at their rear ends, by a crossbar, 0, andconnected, near their front ends, by a fixed cutter-bar, D, which may be of wrought or c'astiron, facedwith steel at its upper surface.
- the shaft c has a-ratchet-wheel, F, keyed firmly upon it, into which a pawl, G, attached to one end of the roller, catches, and causes the shaft to turn with.
- each side-piece B there is attached a shoe, 'N.
- These shoes are rounded. up at each end, as shown at dd, and at the centres of the shoes there are vertical portions, 0, which have, oblong slots, e, in them, through which screws 1? pass into the side-pieces B B, as shown clearly in fig. 3.
- Q represents a bail-shaped rod, the ends of which are curved, or bent inward, or toward each other, to form journals, f f, which are fitted in holes in the side-pieces B B of the framing, a little behind the ends of the roller-shaft a.
- This rod is provided at its centre with a socket, R,
- the cutter M As the machine is shoved along, the cutter M, as it rotates, cuts the grass, the edges of the blades 0, as they pass over the edge of the cutter-bar D, severing it.
- the joiu'nals ff of the bail-shaped rod Q are allowed to work freely in the side-pieces B B, so that in pushing the machine along, said rod will not interfere in the least with the equilibrium of the frame on the shaft of roller E.
- This device will operate and cut grass quite close to trees and shrubs, without injuring or cutting them.
- the rotary cutter M cannot spring-a result due to the material, (cast-iron,) and the spiral form in which it is cast.
- the whole device complete, ready forms, may be furnished at a small cost, and there are no parts lia ble to get out of repair or become deranged by use.
- the frame By attaching the handle to the frame of the ma .chine, by means of pivots or hinges, the frame, it will be seen, is allowed to adjust itself to the inequalities of surface over which it may pass, without any labor,
- cutter of this class cannot be made inflexible, or sufiicieutly stiff, when composed of a series of parts eonuected together, the blades, or cutters will spring, yield, or give, and render the operation of the machine very imperfect.
- the spiral rotary cutter M provided with the cutting-cdges'c, when hung above the cutterD in a frame, which is adj nstable upon the. shoes N, in the manner and for the purpose specified.
- the frame mounted on the roller E, and provided with the adjustable shoes N, rota-i'y'cutter M, fixed cutting-blade D, bail Q, and handlesS, all operating substantially as'aucl for the purpose set forth.
