Abstract
The present splitting saw generally comprises an elongated housing one end of which generally constitutes a drive end and the opposite end a driven end for an endless saw blade. The drive end mounts an electric motor connected by gearing to a drive pulley around which the drive end of said saw blade is trained, and the driven end is provided with a takeup pulley over which the opposite end of the pulley is trained. Both the drive and the driven pulleys are provided with radially and uniformly spaced drive pins, and the saw blade is provided with apertures that are spaced to receive the outer ends of said drive pins thereby effecting drive connections between the drive pins and the pulleys and the apertures in the saw blade.
Claims11
A portable carcass-splitting band-saw assembly comprising, in combination, an elongated body having:
- one hollow end mounting a transverse axle that extends outwardly across said hollow body end, and a drive pulley provided with an outer rim and mounted on said axle,
- a fixed cam having a semi-circular outer face that extends around approximately 180.degree. between the upper and lower end of the cam, and
- a plurality of spring-depressed drive pins that extend radially through the rim of the mentioned drive pulley, said pins being aligned with the mentioned semi-circular cam face and are projected by said face to extend beyond the outer surface of the pulley rim and into driving engagement with that portion of a bandsaw blade that is trained over the portion of the outer surface of the mentioned rim that is coextensive with the semi-circular surface portion of the mentioned cam.
A band assembly having a drive pulley, an endless band-saw having a plurality of equally spaced holes and mounted around said drive pulley, and cleaning means adapted to engage the surface of said drive pulley, comprising:
- (a) a plurality of retractable spring loaded pins mounted on said drive pulley, said spring loaded pins being normally biased inwardly for engaging at least several of said plurality of equally spaced holes;
- and
- (b) projecting means mounted in close proximity to the inner surface of said drive pulley for projecting said pins outwardly during a portion of the rotational cycle of said drive pulley whereby said pins are urged into at least several of said plurality of equally spaced holes to thereby provide traction between said drive pulley and said band-saw without interfering with the operation of said cleaning means.
The combination as described in claim 13 and wherein said projecting means mounted in close proximity to the inner surface of said drive pulley comprises a first cam mounted to project said pins outwardly during a portion of the rotational cycle of said drive pulley;
- and
- (a) said second projecting means comprises a second cam mounted to project said pins outwardly during a portion of the rotational cycle of said rotational pulley.
