Abstract

160,727. Jerram, A. E. Oct. 17, 1919. Lawn-mowers.-The side frames 10, 11 of a lawn-mower are stayed together by cross-members 60, 61, 62 upon one of which the carrier 81 for the ledger blade 80 is pivoted, the movement of the carrier about its pivots being controlled by means mounted on another cross-member. The . cross-members are preferably permanently secured to the frame on one side and detachably on the other. The rotary cutter 20 and the rollers are preferably mounted in self-aligning bearings so that slight distortion of the frame will not affect the working of the machine. The ledger blade 80 is provided with two cutting edges and may be reversed on its carrier 81 which is formed with three lugs 85 bored slightly aslant in the horizontal plane to receive a long bush 86 bored equally aslant in the other direction and rotatably fitting on the cross-member 61. The middle lug 85 is provided with a cotter pin by which the carrier 81 may be locked to the bush 86 so that the carrier and the bush may be moved about the member 61 to adjust the knife 80 relatively to the rotary cutter. This movement is given by rotating a hand-wheel 93 operating a worm engaging a worm-wheel on a sleeve enclosing the cross-member 62 and carrying eccentrics at each end, the straps of these eccentrics being connected by links to lugs on the carrier 81. Relative movement of one end only of the ledger blade towards the cutter may be given by moving the bush 86 within the carrier. To adjust the height of the cutter-above the ground, the forward roller 70 is rotatable upon an axle 71 which is carried by crank arms 72. adjustable round an axis 73. The one crank arm is provided with an extension 74 formed with a pin which can move in a slot 77 and which carries a nut 78 by which the arm may be locked in the adjusted position. The slot 77 is formed in a forwardly extending part of the frame which serves as a foot for supporting the mower when stored as described in Specification 160,728.
