Q IMPROVEMENT SAWlNG-MACHINES.
Specification forming part of Letters Patent No. 46,833, dated March 14 1865..
To aZZ whOm Jt flmg concern:- ,I
Be it known that I, EDsELL TOTMAN, of Columbus, in'the county of Warren and State Improved Sawing-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable same, reference being had to the accompanying drawings, forming part of this specification, in which- I Figure 1 is a side sectional view of this invention, taken in the line on 00, Fig. 2 Fig. 2, a plan or top view of the same; Fig. 3, a side view ofa portion of the same.
Similar letters of reference indicate like parts.
This invention consists in combining a re ciproeating and a circular saw in such a manner that a sawing-machine may be obtained for sawing either large or small logs, and the machine easily changed, so as to be used in The invention is designed for sawing logs transversely with the grain, such as are commonly termed cross-cut sawing-machines.
A represents a horizontal framing, having the shaft 0, toone end of which the horse or other draft-animal is attached, said frame D port for a portionof the driving-gear, consist- F, on the shaft 0, and also consisting of a By this arrangement it will be seen that moor frame D is rotated. On the lower 'end of the shaft 0 thereis a crank-wheel, H, to which one end'of a pitman, I, is attached, the opposite end of said pitman being connected to a slide, J, which works between guides to a, on the framing A, and has a bar, K, attached to it by a hingeor joint, I). This bar K has a saw, L, secured to it, and it will be seen that as the sweep or frame D is rotated a reciprocating motion is imparted to the saw, the latter being allowed to feed itself to its work by its own gravity, in. consequence-0f the bar K being connected to the slide J by the hinge or joint I). This reciprocating saw L is used for specified.
ing small logs is composed of the following parts.flame horizontal framingA there is placed'an upright framing, consisting of two .serve as a support for the upper part of the shaft 0. On the upper part'of the .shaft 0 there is keyed a pulley, N, around which a belt, 0, passes, said belt alsopassing around a pulley or drum, 1?, on a shaft, 61, between the upper part of the standards a c, and on this shaft (1 there is fitted a swinging frame, Q, composed of two bars, e 6, connected by crossrods f. In the lower end of this swinging frame Q there is .icircular saw, 1%, which is driven by a belt, g, from the pulley or drum P, and below the swinging frame there is a buck or horse, S, 'designed for holdingxthe wood or small logs to be sawed by the saw R. The circular saw, it will be seen, feeds itself to its work by its own gravity in connection with that of. the frame Q.
rangement I obtain a machine which may or? used for sawing either large or small logs and this is a great advantage, for in sawing small logs the circular saw works much more rapidly than the reciprocating saw, and, consequently, if the latter were usedfor sawing small logs the work would be done comparatively slow, for a rapid movement of the reciprocating saw would not answer for sawing large logs-the saw would not only be liable to heat but also to kink or bend and be broken,
It is not, of course, designed to use more than one saw at once. The belt 0 may be cast off from the pulley N when the reciprocating saw is used, or the framing which supports the circular saw, as well'as the swinging frame Q, may be entirely removed, and also the buck or horse S.
I do not claim separately or in the abstract any of the parts herein shown and described;
but
I claim as new and desire to secure by Letters latent- The sawingmachine hereinbefore described, consisting ot 'thc frame A, shaft (J, pulleysN P, swingingframe Q, crank-wheel H, pitman I,
and saws It L, constructed and arranged as I'Vitnesses (l. OADY, HAWLEY DAVIS.
