Abstract: The clipper lever support insert may be inserted into a clipper lever. A finger insert may have two approximately parallel sides formed from metal. The sides may be shaped to the approximate form of a drive finger side. A shaft end insert may have a plurality of sides approximately in the shape of a rectangular box formed from metal. The sides may be shaped to the approximate form of a motor end cavity side.

Abstract: Disclosed is a hair clipper having a moving lower blade, in which the lower blade moves so that upper and lower blades reciprocate in opposite directions and cross each other. In the hair clipper, an eccentric cam is connected to a rotary shaft of a motor installed in a main body, and an eccentric shaft formed on the eccentric cam is inserted into a fixing groove formed in an upper blade fixing plate and vibrates horizontally, the lower blade is mounted on a blade support, such that the lower blade can move horizontally, and is fixed to one end of a link, the central portion of which is fixed to the blade support, and the other end of which is fixed to the lower surface of an upper blade fixing plate, to which an upper blade is fixed, and thus, when the upper blade fixing plate vibrates horizontally by the rotation of the motor, the lower blade vibrates on the blade support by the link in the direction opposite to the vibration of the upper blade.

Abstract: A shear device includes one or more fixed blades secured to the front portion, one or more cutter blade coupled to a lever and moved relative to the fixed blade in a shearing action by the lever. A cam member is rotatably received in the housing and engaged with the lever, and a motor coupled to the cam member for rotating the cam member to move the lever in a reciprocating action and to move the cutter blade relative to the fixed blade in the shearing action. The cam member includes a radially outer peripheral portion slidably received in a notch of the lever.

Abstract: A de-hiding tool includes a handle section with a long blade cover, a pair of counter-rotating and oscillating cutting disks mounted face-to-face and driven by eccentrically mounted drive arms operated by a self-contained air motor, a short blade cover mounted to a side of the cutting disks opposite from the long blade cover, and an adjustable blade support which includes an adjustment shaft extending through the blade covers and providing a means for adjusting the spacing between the blade covers from the outside of the tool housing. The blade adjustment system includes an insert with threads accessible from the outside of the housing to adjust the size of a gap between the blades by corresponding movement of a spacer inside the cover. This controls the face-to-face pressure on the blades to make them cut more efficiently and to compensate for the blades being ground thinner when resharpening the blades.

Abstract: An interlock structure of the cable type for stacked plural drawer cabinet structures which limits the opening of drawers to a single drawer and prevents plural drawers being opened at the same time. An elongate base or frame is mounted in the cabinet adjacent to the drawers. The frame supports plural (one for each drawer) eccentric blocker elements and adjacent follower elements and supports at one end a provided slider element having limited movement. A cable is attached at one end to the slider and at the other end to the frame with an intermediate loop which provide two cable courses, one of said courses threaded on the successive blockers and the other course operably threaded over the respective adjacent followers maintaining the respective blockers and followers in operative engagement. The blockers are moved by interference engagement by a selected drawer.

Abstract: A power skinning knife with a drive mechanism that may be easily removed for cleaning and a high efficiency pneumatic motor. The main drive gear is located on the same side of the pinion gear as the drive mechanism cover plate permitting removal of the drive mechanism without removing the drive motor. Other improvements include a replaceable main bearing plate in case of bearing failure damage, a combined drive mechanism cover and barrier plate manufactured of a different material than the remained of the housing to increase wear resistance, hollow drive pins to reduce the oscillating mass and operating vibration, and a spring mounting for the motor to assure accurate alignment of the motor and gearing system after each disassembly of the tool.

Abstract: To mow even soft grass more tidily in shearing mode without kicking pebbles, a pair of two grass cutting wheels are pivotally driven by an engine in two mutually-different directions. One cutting wheel is slidably fixed relative to the other cutting wheel for safety. The mowing machine can be used in common to shear off grass on the ground and trim a garden tree by adjusting an angle between a hollow grip pipe and the machine cutting surface.

Abstract: A microsurgery saw comprising drive means for producing rotary motion, rotary-to-lateral converting means operatively driven by the drive means, saw support means for pivotally supporting a microsurgery saw operatively connected to the converting means for transmitting lateral drive motion to the microsurgery saw, drive casing means surrounding and positioning the drive means and saw support casing means surrounding and positioning the saw support means is disclosed.

Abstract: A wool shearing handpiece enclosed within a casing through which extends a drive fork driven at a rear end for oscillation about an intermediate pivot to reciprocate at an open forward end of the casing a cutter across a comb, and wherein the closing force between the cutter and the comb is derived from a frame having a pair of depending arms which at least partly span and bear down upon a forward end portion of the fork with an adjustable force.

Abstract: An improved clipper and oscillating drive lever for engaging a slot in the movable cutter of a clipper. The distal end of the lever has two resilient prongs biased to a first spread greater than the dimension of the slot such that the prongs must be squeezed together to engage the slot. Some preferred embodiments include inwardly-turned tips. Reduced noise and improved cutting efficiency are provided.

Abstract: A drive mechanism for a dry shaver comprising a shear foil and a cutter reciprocatory relative to the shear foil includes a single-phase synchronous motor having a drive shaft. A cam is mounted on the drive shaft, and a transmission roller is constantly in contact with the cam. The surface of at least one of the cam and the transmission roller is provided with a layer approximately 1 mm in thickness of an elastic material.

Abstract: The clipper is driven by a flexible shaft from a stationary motor supported by a stand clamped to an edge of a grooming table. Because the motor is not incorporated in the clipper casing as characterizes prior art clippers, the casing is lighter, operates at a cooler temperature and can be made more powerful by utilizing a motor of higher rated horsepower and rpm than the smaller type motors incorporated in a clipper casing.

Abstract: An arrangement for removing skin of slaughtered animals has a housing substantially forming a handle, two cutting disks having a central plane corresponding to a central plane of the housing, a drive and transmission, a separating wall formed of one piece with the housing and separating the transmission from the cutting means as well as including a center plate extending substantially in the region of the central plane and a limiting plate extending substantially normal to the latter, a spacer ring abutting against the central plate and supporting the cutting disks, and two covers of which one cover is connected with the central plate and partially supports the eccentric shaft, and the other cover abuts against the limiting plate and is pressed against the spacer ring, wherein the central plate of the separating wall has a free end portion which is overlapped by end portions of the covers.

Abstract: A portable power driven implement having a motor as a power source and a drive train which is compact and the components of which are readily accessible, in which the motor rotates drive means which is connected to rotate output means, and in which a linking member connected to the rotating output means imparts reciprocating motion to a tool member, the linking member spanning the drive means and configured to avoid interfering engagement therewith.
