The Buffalo Specialty Company, Buffalo, N.Y., is manufacturing the tandem power hack saw here illustrated. Although it comprises two saws in one it is said to be simple in mechanism and to contain an unusually small number of parts. The parts, however, are reinforced wherever strength is demanded, thus insuring rigidity and freedom from vibration, preventing the breakage of saw blades and making it possible to secure a smooth, straight cut. The bearings are all bushed with bronze and fitted with brass oil cups, excepting the ways, which are babbitted throughout. This is said to secure perfect alignment and great durability with a minimum of attention. While ordinarily run at a speed of 85 revolutions the tandem machine has been operated at a speed of 110, cutting 2-in. tool steel with practically no evidence of wear on the saw blades. This work is accounted for by the flexible or accommodating feed of the tandem, together with the lifting motion of the saw frame and arm on the return motion. An automatic shut-off is provided, which stops the saw the instant the cut is through: there are also vises for holding the material
being sawed, arranged with swivel jaws, which adjust themselves to grip iron or steel of any shape, whether straight or tapering. Among the economic reasons urged for the use of this tandem saw are that the price of the tandem is less than the price of two good single machines of the same capacity; that it requires but one belt, and therefore saves one belt, one pulley and often an entire countershaft. It also saves floor space, power and cost of installation, as well as the wear and tear of an additional machine. The two saws of the tandem may be operated together or separately as desired |
