摘要： To prevent formation of burrs and splinters upon sawing a workpiece (3) with a continuously moving saw band (9) operating in a cutting movement direction (18), the saw band (9) is guided at an inclination or angle (19) with respect to a support surface (2) of the workpiece (3) at least just before cut-through, in which the angle (19) is open or away from the support surface, with respect to the cutting movement direction (18). A saw band holder (8) can be tipped or tilted about a pivot axis (7) offset from the support surface, or guided, already initially, at the angle which, preferably, is between about 1.degree. and 10.degree. and, especially, about 3.degree..

摘要： A tree felling apparatus mountable to a vehicle includes a frame defining an opening for receiving a tree and a chain saw mounted for linear movement across the opening for felling the tree. One side of the opening is defined by an anvil having a sharpened edge for increasingly engaging the tree as the frame is advanced to receive the tree within the opening. The sharpened edge also extends sufficiently so that it overlaps the leading edge of the chain saw as the saw completes its cut. The anvil thus serves as a stationary, stable pivot point for the falling tree and protects the underlying chain from the force of the falling tree. Wedges are spaced across the saw bar of the chain saw for directionally felling the tree.

摘要： A throttle actuating mechanism is employed in conjunction with a chain saw which has a trigger and is mounted for pivotal movement about a rotary axis from a rest position toward a workpiece. The mechanism includes a lever pivoted coaxially with the rotary axis of the chain saw and carrying an adjustable pin. The pin is engaged by the chain saw trigger when the chain saw is pivoted toward the workpiece, whereby the lever pivots in a first direction along with the lever. A spring yieldably opposes pivotal movement of the lever in the first direction, thereby causing the pin to actuate the trigger when the chain saw leaves its rest position. The lever engages a stop while pivoting in the opposite direction and before the chain saw reaches its rest position, whereby the trigger is deactivated when the chain saw is in its rest position.

摘要： A metal cutting band saw equipped with blade twisting guides and pivotal, scissors-like mounting which enables the saw to be used as a cut-off or mitering tool, is configured to provide for maximum depth of cut by locating the blade guide mounting bar in a position which does not restrict clearance distance to less than the separation distance between the blade runs.

摘要： A horizontal power band saw having a frame fabricated of rigid weldments (as opposed to castings) thereby to appreciably lower the cost of the band saw. A system is disclosed for accurately pivotally mounting the saw head on the saw bed, for adjusting the pivotal axis of the head parallel to the bed, and for positively holding the head in desired relation with the bed so as to enable the head to be repeatedly and accurately raised and lowered while the blade of the saw is held in a plane generally perpendicular to the bed. The saw blade is tensioned in such a manner that a desired tension load can be accurately applied to the blade and so that the tension load on the blade can be accurately read out. Also disclosed is the provision of guides for holding the blade in a desired cutting orientation with the guides including guide rollers, thrust bearings, and carbide blade guide inserts wherein the rollers, bearings, and inserts may be readily and accurately adjusted so as to accurately guide and hold saw blades of varying thicknesses. Further the band saw includes a quick-acting vise enabling the saw operator to quickly release a work piece and to positively grip the work piece in another position along its length so as to enable repeated cuts on the work piece to be accurately and rapidly accomplished.

摘要： A machine and method for mechanically and simultaneously sizing and cutting multiple strands of flexible metallic conduit to desired lengths, and for facilitating the application of a fitting to either end of the respective resulting lengths, in which the conduit is simultaneously drawn, by a roller drive, from a number of rolls of same in parallel strands and is fed past a cutting station the conduit length desired, after which feeding of the conduit strands ceases and the conduit lengths are simultaneously severed from the row of strands by sawing. The machine includes a device for mechanically rotating the individual end fittings for the conduit length ends, whereby the machine operator can individually manipulate the individual conduit length ends to apply same to the device to permit the end fitting for same to be mechanically rotated into its fully seated position in the conduit end, and an attachment that permits the conduit wiring to be mechanically fed into same and cut off at the right length to complete the conduit assembly.

摘要： There is disclosed a portable band saw having a travelling band cooperating with pulleys so located that the front and rear band portions are positioned in relatively close but spaced relationship. The pulleys rotate parallel axes. Longitudinally spaced guide means are incorporated which cooperate respectively with the front and rear portions of the band so that, with adjustment, the guide means cause the band to be disposed with the rear portion in desired alignment with the front portion, thus permitting the portable band saw to selectively make either straight or angular cuts.
