Abstract: The invention relates to a guide bar having a main member made of solid material for a motor chain saw. The guide bar has two flat sides and narrow edges defining a saw chain path. A cutout extends through the main member of the guide bar for reducing weight. The openings in the main member defined by the cutout are closed by cover plates for maintaining the stiffness and are attached to the main member of the guide bar. A fill body is seated in the cutout with an approximately precise fit and is connected to the cover plates in a force-transmitting manner. In this way, a higher torsion stiffness is obtained while at the same time retaining the reduction in weight.

Abstract: The cutterhead includes a cutting filament wound on a spool and this cutting filament is adjusted with respect to its effective cutting length in dependence upon the rotational speed of the cutterhead. The switching point for the automatic feed must be precisely matched to the drive speed in order that the desired effective cutting length is maintained. In order to assure the desired effective cutting length, a spring is provided which is adjustable with respect to its biasing force by means of an easily accessible adjusting member. This biasing force is matched to the speed-dependent centrifugal force such that the spool is released at a predetermined speed of the cutterhead.

Abstract: In connection with a conversion set for a portable circular saw, which latter comprises a housing, an associated electric drive motor with output shaft and, if necessary, also a gear, and at least one handle, it is proposed to attach to the basic unit remaining after removal of the circular saw blade a chain-saw adapter attachment, to convert the portable circular saw in this manner into an electric chain saw and to secure the chain-saw adapter attachment in place by means of mechanical stops provided on a main bearing plate and coacting with the gear housing of the circular saw and, in the axial direction, by tightening a screw upon the output shaft of the circular saw projecting through the drive pinion for the saw chain.

Abstract: A hand-held tool, such as a hammer drill or chipping hammer, includes a housing with a driving unit for supplying the driving force for the tool with the driving unit generating vibrations. A handle is mounted on the housing and is displaceable in the direction of the main vibration axis. A stop for the forward movement of the handle is provided by an electromagnet. The electromagnet is formed by a yoke, an armature and a magnetic coil and exerts a controlled constant force on the handle and the housing independently of the position of the handle relative to the housing. The electromagnet can be controlled depending on the position of use of the hand-held tool.

Abstract: A pipe scraper for scraping the end of a plastics pipe such as a plastics gas main or water main has a framework (10) in which is journaled a helically bladed rotary cutter (14) driven by means of a lever (17). On the shaft carrying the cutter is a pinion (16) which meshes with a larger pinion (19) driving a friction surface roller (21). The cutter is held in a Reed clamp and as the lever (17) is turned it rotates the helically bladed rotary cutter so as to scrape a low angle helical scrape approximating a longitudinal scrape. At the same time the rotation of the roller (21) causes the whole framework to rotate around the surface of the pipe so as to scrape the whole end peripheral surface.

Abstract: A one-piece razor handle molded from resilient plastic has spaced-apart opposing side walls joined at an intermediate location by a neck. The walls diverge upwardly from the neck into upper portions for gripping a blade cartridge, and extend downwardly to a spacer that extends between the lower portions of the wall. The lower portions of the walls, between the neck and spacer, are resiliently squeezable. The neck acts as a fulcrum so that the upper portions pivot outwardly as the lower portions are squeezed inwardly. A base joins the bottoms of the walls extending past the spacer.
