1st drive: The drive of the electric hobby hacksaw is particularly characterized by its own drive motor, which is firmly mounted in the substructure and the speed can be continuously regulated.

ufir speed, is generated by a diemer (also called chopper) The speed is very important because apart from wood, also metal or plastic saw blades, for the respective Material processing can be clamped.

g.Double saw bow with tensioning device The double saw bow is specially marked by legs .- _: blade clamping device, whereby fine and coarse, thick and thin saw blades intended for wood or other metals can be carefully clamped. The double saw frame, which is made of two identical flat materials, is riveted together from the back to the center of the saw frame of the Sr _r -blattes, the screws are tightened and the saw blade is slightly tensioned by the clamping screw in the clamping device. The saw bow is completely free of distortion thanks to its two identical side brackets.

p. The Schwabbe l (Piberationsschmirgelbrett) Until now, the Schwabbel is unique for a hobbyist. In conjunction with the saw, however, it is very important because the sawn edges are sanded the same way. Since a buff only makes short forward and backward movements, it should be noted in particular that there is no risk of injury to a conventional rotating emery disk . \

Main parts :

All parts are finished before assembly. '' Base plate, spacer frame, 2 side walls in which all movable and immovable parts of the machine The saw frame, buffing device and motor with a small V-BELT DISC.

Assembly :

The spacer frame is mated to the base plate, then

the limce side wall is attached to the left side of the distance frame screwed on, then the motor with the flange is inserted into the flange bore from the outside left ;: and screwed to the sideband with 4 screws. before ι the engine is the Kuroelwelienlarer in the side wall ι pressed into which the cylinder shaft is inserted, we-u.

The coarse iveilbeltenscne made of plastic is cast onto the crankshaft. After inserting the turbo shaft, the four V-belts are loosely fitted over the large and small V-belt pulleys 7, "Jyen. Now the fully assembled fciägebürel with the bearing pin is inserted into the bearing pressed in at the back, then A connection is established by a connecting rod from the crankshaft to the saw bracket. The fe.-tic mounted buff is then placed on the upper spacer frame, then the opannscnrauDJ is from the clamping device of the saw bracket to the rear rubber bearing of the buff in the pannvorrichtun ~ screwed in. Now there is an operation from the motor via the V-belt to the crank shaft, from this via the crank rod

to the saw frame uid from the saw blade tensioning screw of the tensioning device; to scabble inevitably ρ: produced. The further assembly consists in that the recnce side wall with the counter bearings of the saw frame and crankshaft is pushed into this and the side wall is screwed to the spacer frame. After hang up and Säjre- \ diagram Bolt is still the -. "Iemer connected to the motor end of the Monoage.

Claims (1)

June 7, 19 78 By Gm 5745 Protection claims 1. Electric hacksaw, especially for DIY enthusiasts, with a Saw frame and with a sowing blade that can be pulled into the seed frame, marked by the fact that the S ^ bracket (11) pivotally mounted and at a distance from its bearing point (22) can be driven by means of a crank (6), which never corresponds to the output a continuously controllable drive motor is connected in its speed. 2. Hacksaw according to claim 1, characterized in that that the saw bow (11) consists of two essentially identically designed and cover bracket parts fastened to one another is formed. 3. Hacksaw according to claim 1 or 2, characterized in that that the S /: annf laugh the saw bow (11) for clamping a saw blade (20) are slightly oeboaen outwards. 4. Hacksaw according to one of the preceding address, thereby characterized in that it has a clamping device (23, 24, 27) for the saw blade (20), the clamping member of which (27) is connected to a buff (33) which can be moved back and forth in its longitudinal direction. 5. Hacksaw according to claim 4, characterized in that the buff (33) is displaceable on a base (28) is, which also serves as a spacer between two parallel side walls (12). 6. Hacksaw according to claim 4 or 5, characterized in that that the buff (33) carries a rubber ring (36) through which the clamping member (27) passes. - -2, - ' ■ June 7, 19 78 By Gm 5745 7.
