IMPROVEMENT IN BAND SAWlNG-MACHINES.
Specification forming part of Letters Patent No. 130,615, dated August 20, 1572.
Specification describing an Improvement in Band Sawing-Machine, invented by HOSEA D. BLIss, of Hamburg, in the count-y of Fremont and vState of Iowa.
In the accompanying drawing, Figure l is a topviewofmyimprovedsawingmachine. Fig. 2 is a back view of lthe same..
Similar letters of reference indicate corresponding parts.
This invention relates to improvementin the class of band sawing-machines wherein the saw is so hung as to be inclined from a vertical plane when desired; and it consists, chieiiy, in the construction and arrangement of parts whereby the standard carrying the pulleys upon which the saw is mounted may be ad- Y justed at various angles to the reciprocating table with ease,
dispatch, and certainty.
A in the drawing represents the sawing-machine table or frame, ot suitable size, form, and material. and C the Aupper B is the lower drum holding the band-saw D. The shaft c of the lower drum has its bearings in the frame.
A, and serves also as a pivot for the lower end of the post E, in whose upper part the shaft b of the upper drum has its bearings. The bandsaw is laid around the two drums and is operated by means of a crank-handle, F, which is applied to the shaft a. On the latter the post E can be inclined at will to bring the cutting portion of the saw in a similar inclined position. A slotted segment, d, on the post, receiving a set-screw, e, serves as a means of fastening the post in any desired position. The crank Fis slotted where it connects with the shaft c, and can be lengthened or short-` ened in consequence, in order to give the requt site amount of power. For giving theright tension to the saw the shaft b is hung in a block,
,which can be set up or down in the slotted upper part of the post E. g is a slide in that part of the table through which the saw passes, and is moved in or out, as may be required, whenever the saw is changed from a vertical to an inclined position, or vice versa. Gris the sliding carriage on which the wood is fed to the saw, and H is a ledge or rest arranged on top of this carriage. The rest H is pivoted bya pin, It, and can thereon be turned to hold the wood obliquely or at right angles to the saw, as may be desired. lBy a screw, ,-passing through a slotted segment, j, the rest H can be secured in suitable position.
`I propose to use a band-saw with teeth of such form that it can be reversed by being turned inside out whenever the teeth are blunt on one side. Regular V-shaped teeth, properlyupset, will best answer this purpose.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The improved sawing-machine, formed of.
the table A, slide g, carriage G, pivoted guide l-Ij, pivoted post E, slotted adjusting-plate d, pulleys B (l, band-saw D, and crank-shaft, all constructed, arranged, and operating as specitied.
