Abstract: The saw includes a frame having an opening with a pair of proximate and distal blade retaining chucks located on respective sides of the opening. A saw blade is retained between the pair of chucks. A plurality of pulleys are attached in spaced relation to the frame including pulleys on opposed sides of the opening. A flexible band is entrained about each of the plurality of pulleys, with the band having a first end operatively connected to the proximate blade retaining chuck and a second end attached to the distal blade retaining chuck. A reciprocating drive is attached to the proximate blade retaining chuck. The reciprocating drive and the flexible band work in conjunction to pull the blade in opposite directions during each cycle of the drive. An alternative embodiment of the present invention may take the form of a stationary table saw.

CPC classification number: B23D49/006 , Y10T16/498 , Y10T83/8878
Abstract: A power saw has two oppositely reciprocating saw blades guided and supported in a receiving slot in a support plate. The blades are supported during sawing along shoulders on their outside by lower edges of support sections of the support plate. The arrangement is such that forces generated in operation during cutting press the saw blades together in the area of their teeth. This prevents saw dust, chippings etc. penetrating between the two saw blades. Preferably, the thickness of the saw blade shoulders are not greater than half the thickness of the saw blades, and preferably no greater than the thickness of the support section edges. The teeth of the saw blades may be so ground and arranged that the resultant force on the teeth during cutting also forces the saw blades together at their teeth.

Abstract: A saw blade comprises a support member having at least one edge, and, spaced along that edge, a series of slots in each of which is secured a saw tooth and in which a portion of the tooth is located within the slot and a further portion extends beyond the slot to overlie a portion of a surface of the support member.Part of the slot and a part of the tooth may be sector-shaped, each slot may include an entry portion with side edges and a base edge or edges, and the tip of the sector-shaped part is located centrally of the base edge, the sector-shaped part communicating with the entry portion via an opening in the base edge whose sides are rounded and which are a tight fit with a mating portion of a tooth, the remainder of a tooth fitting into the slot with some clearance.The invention also extends to a tooth for the saw blade, the tooth having a cutting portion and a body portion to locate in said slot.According to a further aspect of the invention, a cutting blade has hardened cutting teeth located in the slot in the blade, there being a support edge or edges spaced from the cutting edge of the blade and substantially parallel thereto which engages a support surface on a guide for the blade.The support edge(s) may be provided by a strip fixed to the blade or by edges on the teeth remote from their cutting portion which project beyond the surface of the blade.
