A movable clipper blade is defined adjacent to front and rear ends thereof with front and rear oil passages and is positioned underneath the oil pad, such that the front and rear oil passages are communicated with oil storing grooves defined on a lower surface of the movable clipper blade, to supply oil between the movable clipper blade and a fixed clipper blade.

Abstract: In a hair-cutting apparatus (1) and in a toothed cutting device (7) for a hair-cutting apparatus (1) the toothed cutting device (7) comprises a first toothed cutter (13) and a second toothed cutter (24), which lie against one another in the area of their cuttertooth rows (18, 25) and which each have at least one supporting limb (20, 21, 46, 47) in their areas which are remote from their cutter-tooth rows (18, 25), and of which one toothed cutter (24) carries an intermediate element (48) of a low-friction material, which comprises at least one intermediate element portion (49, 50) interposed between two facing supporting limbs (20, 46, 21, 47), and furthermore it has the advantageous feature that the at least one intermediate element portion (49, 50) of the intermediate element (48) carried by the one toothed cutter (24) has a smaller dimension in the toothed cutter direction (17) than the at least one supporting limb (20, 21) of the other toothed cutter (13), which last-mentioned limb 20, 21 faces the at leas

Abstract: A hedge cutting bar is shown and described as having rivets for securing a cutting blade between a retaining blade and a stationary blade. The rivet structure includes a central flange and distal hubs whereby the central flange may occupy slots in the cutting blade while the hubs attach within respective mounting apertures of the stationary blade and the retaining blade. The thickness of the flange is greater than the thickness of the cutting blade whereby a gripping force provided by the rivet is taken up at the flange to avoid pinching of the cutting blade between the stationary blade and the retaining blade. The described fastening arrangement is less suspectable to loosening under the vibrational forces imposed during use of the hedge cutting bar than that of prior fastening arrangements.

Abstract: An improved heavy duty snips and shears useful for cutting sheet metal or other stiff or rigid material. The improved snips and shears include a lower blade having a substantially horizontally disposed body. The body of the lower blade comprises a first horizontal section, an intermediate downwardly inclined section, and a second horizontally disposed section. The inner edge of the intermediate section forms a cutting edge which is turned upwardly such that the cutting edge is raised above the first and second horizontal sections. The upper blade of the snips and shears is pivotally attached to the lower blade and includes a downwardly extending heel disposed at the rearward end of the cutting edge. A machine ground boss is formed on one of the blades and provides a friction surface which provides a pressure point of minimum area to facilitate sliding contact of the two blades.

Abstract: A shear is disclosed in a preferred form which is particularly suited for cutting and trimming hair and which includes means for varying the length of stroke of the cutting blade or blades which reciprocate generally parallel to the longitudinal axis of the handle, so that the unit can be manipulated in a manner similar to a comb or brush. The blade drive includes a transmission comprising a pair of eccentrics which are selectively phaseable to provide full range of stroke by addition and subtraction of their eccentric throws. The eccentrics are retained in their selected phase relationship by spring and frictional means which provide an overload release permitting the eccentrics to rephase to zero stroke when the imposed load overcomes the phase-retaining means. Control of the unit is effected by a rotatable and depressable button which controls the drive motor, adjusts the blade stroke by phasing of the eccentrics, and levers the cutting blade or blades from a retracted position into a cutting position.

Abstract: The single-toothed blade is pivoted at its rear end and driven at its middle section in arcuate reciprocation over the teeth of a fixed base plate by an electric motor. The blade and the slide of the crank-slide blade drive mechanism comprise the wear parts of the sickle-shear and as a subassembly is readily detachable from the crankpin for rapid replacement without the use of tools.
