Abstract

1,152,547. Sawing. ANDREAS STIHL MASCHINENFABRIK. 28 Nov., 1967 [3 Dec., 1966], No. 53983/67. Heading B5L. A portable power saw comprises a rigid connection 10 between handles 8, 9 connected to a motor and motor housing 1 by means of vibration damping bearings 13, 23 arranged one at the front and one at the rear of the motor housing, the rigid connection consisting of a frame arranged above the motor housing and having its edges extending approximately parallel to the edges of the motor housing. The motor has a guide 3 for the bar 5 of a chain saw and at its rear is secured an extension 7 having a forked end carrying a bolt 14 on which are a pair of conically-shaped rubber sleeves 13<SP>1</SP>, 13<SP>11</SP>. A clip 17 embraces the sleeves and is secured to one end of handle 9, the other end of which is secured or integral with the frame 10 which is trapezoidal in shape and of generally U-shaped cross-section. At its other end the frame is secured by a bracket 19 to the handle 8. The frame is also connected by a clip 24 to a pair of rubber sleeves 23<SP>1</SP>, 23<SP>11</SP> on a bolt carried by a bracket on the motor housing. The front handle may be in the form of a stirrup which is secured by its lower end through a vibration damping bearing to the motor housing.
