Abstract

904,081. Rotary-scythe lawnmowers. WOLFGERATE G.m.b.H. Nov. 24, 1960 [Nov. 25, 1959; Sept. 8, 1960], No. 40472/60. Class 6(3). In a rotary-scythe mower wherein the prime mover is an electric motor M mounted on and insulated from the mower frame 1 and the upwardly-projecting part of the motor is protected by an insulating cowling 4, the cutter blade 6 being mounted on the motorspindle 11 by means of a hub 7, 8 which insulates the spindle from contact with electrical conductors. The motor is mounted on the frame 1 by rubber bushes 2 having integral studs which are engaged by nuts 3, there being no electrical contact between the motor and the nuts 3. The plastic cowling 4 is in two parts, the upper part having ducts 10 for ventilation, an airstream being produced by integral vanes 8<SP>11</SP> on a dish-shaped part of the hub 8. The blade 6 is sandwiched between the member 8 and a cap 7 with an integrallyembedded screw 9 which engages the spindle 11. In Fig. 3, the hub-portion 28 has labyrinthinl portions 29 which mate with similar portions 30 on the lower part 5<SP>11</SP> of the motor cowling.
