Abstract: A scotch yoke mechanism for converting rotational movement into reciprocating linear movement and having an adjustable stroke length. The scotch yoke mechanism includes a stroke length toggle eccentrically connected to a cam such that the stroke length toggle may assume one of first and second positions. The first position defines a first stroke length which is shorter than a second stroke length defined by said second position. Rotational movement of the cam causes the stroke length toggle to assume the first position when the cam is rotated in a first direction to assume the second position when the cam is rotated in a second direction opposite the first direction.

Abstract: The invention describes a cutting knife for a cutting tool for cutting through adhesive beads on glass panes of vehicles, having a cross section that is bent into a U-shape and comprises a first limb, configured as the attachment part, with a receiving opening for attachment to an oscillating drive, and a second limb that is configured as the cutting part and is joined via an intermediate part to the attachment part of the cutting knife, the intermediate part and the cutting part being shaped such that a distance exists in the radial direction between the center point of the receiving opening and at least one cutting edge. The cutting part has, in a middle region between its outer free end and its angled transition to the intermediate part, a lesser width than at the transition and at the outer end. This results in a reduced susceptibility to breakage.

Abstract: An electric power tool has a motor-driven circular tool that can be clamped by means of a clamping device. A mechanical braking device (2) serves to brake the tool. A safety element (4) prevents improper handling of the electric power tool. In a safety position, the safety element (4) prevents the motor from being turned on and activates the braking device (2). In a release position, the safety element (4) allows the motor to be turned on and the braking device (12) is released. An additional locking mechanism prevents that a clamping lever, needed to actuate the clamping device, can be actuated in the clamped state in the safety position. In the release position of the safety element, the locking mechanism is unlocked.

Abstract: The present invention 10 is an improved electric knife with several enhancements which make it uniquely suited for use in its intended watery environment. In case it is accidentally dropped in the water, it has several floatation chambers 54 in the handle 24 and the end cap 52 that will keep it afloat and nearly water and damage free for a reasonably long period, certainly time enough for any reasonably serious effort at retrieval to be effective. The end cap 52 is highly buoyant, having a sealed partial vacuum chamber 54. The housing has several sealed buoyant air chambers 54 in the. rearmost area to directly offset the weight of the battery pack 36. The motor housing unit also provides buoyancy and floatation by the presence of the water-resistant seal 63 at the juncture of the knife blades 42 and the handle housing 24. The critical areas around switches 44, 50 and access openings are also watertight for operating in wet or rainy conditions.

Abstract: The invention relates to portable handheld work apparatus including a brushcutter, edge cutter or the like. The work apparatus has a drive motor (1) and a cutting tool (2) driven by the drive motor. The work apparatus includes a guide tube (3) for guiding a drive shaft (4) as well as a handle (5) fixed on the guide tube (3). The drive shaft (4) connects the cutting tool (2) to the drive motor (1). The handle (5) is in the form of a handle bracket (8) and can be pivoted about a pivot axis (7) lying transversely to the longitudinal axis (6) of the guide tube (3) for adjusting the distance (a) of the handle to the guide tube (3). A spring action handle bracket holder (22, 23) is mounted between the handle bracket (8) and the guide tube (3). The handle bracket holder is especially vibration dampening and extends with a component in the direction of the longitudinal axis (6).

Abstract: A hand-operated electric tool, especially a jigsaw, has a motor unit provided in the tool housing. The motor unit contains in a motor housing the stator and the rotor. One end of the rotor shaft projects from the motor housing and is mounted in two bearings fixed in the motor housing. A countershaft forms an extension of the rotor shaft and carries a toothed arrangement. The countershaft is coupled to the rotor shaft and is rotatably mounted in a bearing. The rotor shaft and countershaft engage axially with radial play and are coupled non-rotatably by co-operating radial projections and recesses receiving the projections. In the region of the overlapping portions of rotor shaft and countershaft, one of the shafts has an annular portion extending at least over a part of the circumference. The annular portion is substantially in line contact with an adjacent circumferential surface of the other shaft. The line contact permits misalignment of the rotor shaft and countershaft but reduces noise.

Abstract: An electrically operated slicing knife includes an axially movable switch guard overlying the switch of the knife. The switch guard is movable to a first position whereat the switch is uncovered and a second position whereat the switch is covered to prevent a user from actuating the switch. A pair of user actuated buttons control ejection of the blade of the knife. When the buttons are in a first position, the blade is locked relative to the knife handle, and the switch guard when positioned to uncover the knife switch maintains the buttons in their locked position. When the switch guard is moved to cover the switch, the buttons can be actuated by a user to unlock the blades from the knife handle.

Abstract: Power-driven work tool including a shank (2, 3), a drive motor (4), and a working tool (1) driven by the motor. The working tool is rotatable around at least one axis perpendicular to the shank by a controller (8). The controller is attached to the shank and connected to the working tool or a bracket thereof by a wire or rod (10), which transmits pulling or pushing force. The motor (4) is at one end of the shank (2, 3) and adapted to drive the working tool (1) provided at the other end of the shank via a drive shaft extending through the shank. The shank is provided at the end thereof connected to the working tool with a hinge (6) for angular movement of the working means, and the drive shaft provided in the shank (2, 3) is connected to the working tool via a flexible shaft extending through the hinge (6).

Abstract: A device for severing a bonding strip located between and securing together two rigid panels, one of which may be of glass. The device has a flat elongated blade intended, in use, to be inserted between the panels to sever the bonding strip. The device is provided with a rest mechanism adapted to sit on one of the panels being separated to guide reciprocation of the elongated blade, whereby the blade reciprocates in a direction parallel to the panel being separated.

Abstract: The electric kitchen knife has blades (2) connected to the front end of a main housing (5), and the blades (2) move in reciprocal motion to cut food. The main housing (5) has a stand leg (6) projecting from the bottom surface positioned away from the center of gravity towards the blade end. The stand leg (6) maintains the main housing (5) in an upright standing position. Held by the stand leg (6) in an upright standing position on a table (7), the front end of the main housing (5) is raised separating the blades (2) from the table (7).

Abstract: A trimming machine includes a centrifugal clutch for transmitting power from an internal combustion engine to a cutting blade. A manually operated throttle lever controls an output from the internal combustion engine by adjusting an opening of a throttle valve via a throttle wire. A friction member arranged to oppose to a clutch drum of the centrifugal clutch. A first swinging member is connected to the friction member and swings between a braking position to be pressed against the clutch drum and a releasing position to be spaced from the clutch drum. A second swinging member is connected to a connecting point at an intermediate portion of the throttle wire and pivots about a pivoting pin thereof with respect to the first swinging member when the throttle wire is moved by operating the throttle lever.
