Abstract
635,227. Reciprocating saws ; percussive drills. SCINTILLA, Ltd. Oct. 22, 1946, Nos. 31358 and 31359. Convention dates, Nov. 24, 1944 and Feb. 15, 1945. [Classes 124 and 145 (ii)] [Also in Groups XXII and XXIV] A motor-driven hand tool for reciprocating a saw, chisel or file has a motor which is mounted in a housing forming the handle of the tool and which drives means for reciprocating the tool at right angles to the axis of rotation of the motor, and a counter-balance system is provided to balance the reciprocating masses. The motor 1 is controlled by a. switch 1<SP>1</SP> and drives a shaft 3 having a pinion 4 which engages gears 5, 6 of equal size mounted on stub shafts. By means of eccentric pins 7 and 20 engaging slots 8 and 21 in the tool carrier 10 and a balance weight 22, respectively, the latter parts are reciprocated at the same speed but in opposite directions. Alternatively, the eccentric pins may be joined by connecting rods to the reciprocating parts or pins on the reciprocating parts may ride in eccentric grooves in the gear wheels. In a modification, the stub shafts may be journalled in an intermediate plate removable with the tool casing so that another implement such as a compressor may be engaged with a dog clutch on the motor shaft. In a modified drive, Fig. 5, a rotatable drum 36 with internal teeth 42 is driven by a pinion 43 on the motor shaft and has a cylindrical crank member 35 eccentrically and rotatably mounted in it. The crank member has a pinion 37 meshing with and rolling round a fixed internal gear ring 41 and also an eccentric crank-pin 38 engaging a collar 50 on the tool carrier. The diameter D of the planetary pinion 37 is half the diameter of the gear ring 41 and the eccentricity K of the pin 38 is half the diameter D so that rotary motion of the drum 36 is converted into reciprocating motion of the tool carrier. The crank member 35 is recessed at 51 on one side so that the remaining mass forms a balance weight. A slotted support plate 19, Fig. 2, for the work is adjustably fitted at one side of the tool casing and has a roller 18 supporting the tool. At the opposite side of the casing a block 28 may be fitted for mounting the tool in a vice. A cover 27 pivoted on a screw 26 is provided.
