IV. J. WELLS, OF DELAWARE, OHIO.
IMPROVEMENT IN SAWlNG-MACHINES.
To all whom it may concern:
Beit known that I, W. J. WELLS, of Delaware, in the county of Delaware and State 0f Ohio, have invented a new and Improved Sawing-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a vertical section of my invention, taken in the line x a', Fig. 2, Fig. 2, a front view of the same with the feed-rollers in section, as indicated by the line y y, Fig. 3, Fig. 3, a horizontal section of the saine, taken 1n the line z z, Fig. l; Fig. 4, a section of a portion pertaining to the saine, taken in the line z z', Fig. 2.
Similar letters of reference indicate like parts.
This invention relates to a newT and iinproved machine for sawing wood or logs transversely with the grain, and is designed for sawing wood for fuel, and into pieces of requisite lengths for wheel hubs, spokes, and other articles.
The invention consists in certain means of operating a swinging frame carrying a circular saw, arranged in such a manner as to have a rising and failing movement, and used in connection with a 10g or timber feeding inechan ism, as hereinafter fully shown and described, whereby the machine is placed fully under the control of the operator, and rendered capable of working in a perfect manner for the desired purpose..
A represents a framing, which may be constructed in any proper manner to support the working parts, and B is a shaft placed in the lower part of said framing, to which shaft the driving-power is applied.
C is a bar, one end of which is fitted by metal straps a to the shaft B, so that it may rise and fall freely from said shaft as a center. In the free or disengaged end of the bar O there is fitted a mandrel, D, on which a circlilar saw, E, is keyed, said saw being driven by a belt, F, from a pulley, G, on the shaft B, as shown clearly in Figs. l and 3. In the bar U there is fitted a pendent frame, H, which is allowed to swing freely from pivots b, and through this fra-me H a screw-rod, I, passes vertically, said rod working in a female screw in the frame H, which is in fact a swinging nut. On the upper end of the screw-rod I there is a bevel-wheel, J, in which a corresponding wheel, K, on a shaft, L, gears, the rear side of said wheel K being provided with ratchet-teeth or projections c, to form part of a clutch, the other part of said clutch being formed ofsimilar teeth, c', on one end of a conepulley, M, which is placed loosely on the shaft L, and is moved or adjusted so as to be thrown in and out of gear with the wheel K by means of levers d d d, or any other suitable device. The conepulley M has a belt, N, passing around it, said belt also passing around a cone-pulley, O, on the driving-shaft B.
P is a crossbelt which passes around a pulley, Q, on the shaft B, and around a loose pulley, It, on the shaft L, the pulley R having ratchet-teeth e at one side of it, forming one part of -a clutch, the other part of which is composed of similar teeth, e', at the rear side of a wheel, S, which is permanently keyed on the shaft L. The loose pulley It is moved on the shaft L by levers f, arranged in any proper way.
rlhe levers d and j', by which the cone-pulley M and pulley R are moved, have springs T applied to them, which have a tendency to keep said pulleys out of gear, respectively, with the wheels K S, and U U are two lever-catches with which the levers olf engage, said catches, when the levers d j' are adjusted in a certain position, keeping the pulleys M R connected with their respective wheels K S. The levercatch U has a pendent bar, V, attached to it, which extends down over the bar G, and the catch U has a pendent bar, W, attached to it, which extends down and is connected to a lever, X, which projects underneath the bar C. (Sec Fig. 2.)
Y is a horizontal shaft in the framing A, which has a loose pulley, Z, fitted on it, around which a belt, ax, passes from a pulley, bx, at one end of the cone-pulley O 011 the shaft B.
A is a wheel which is keyed on the shaft Y, and has two levers, 0X cx, at one side of it, each lever having a rod, dX,`pivoted at its end, said rods passing through the wheel A', and provided with hooks or lips at their ends, which lap over a iiange, cx, at the side of the pulley Z which adjoins the wheel A. The
inner ends of the levers 0X 0X are connected to a slide, B', on the shaft L, which slide is moved or operated by levers dx, arranged similarly to the levers d f, for operating the wheels K S. On the shaft Y there is keyed a bevel-wheel, C', which gears into a wheel, D', on a shaft, E', the latter having a pulley, fx, upon it, around which a belt, gx, passes, said belt passing around a pulley at one end ot' a roller, F', which is underneath the saw E. A roller, F", may be placed at each side of the roller F', and parallel with it, as shown in F'g. 3.
'Ihe operation is as follows: The shaft B being operated by any convenient power, the cone-pulley M is thrown in gear with the wheel K, and the latter rotates the screw I, which feeds down the bar O and the saw E, the latter being rotated by the belt F, and acting upon the log or timber on the rollers F' F" F". As the saw completes its cut, the bar C strikes the lever X, and thereby actuates the catch U, so as to release the levers d, and admit of the cone-pulley M being disconnected from the wheel K, and the pulley Q, being then thrown in gear with the Wheel S, the motion of the screw I is reversed, and the bar O and saw E moved upward, until the bar C strikes the pendent bar V, which causes the catch U' to be actuated, and the wheel Q, to be disengaged from the Wheel S. The operator then actuates the levers dx, and connects the loose pulley Z with the wheel A', and thereby gives motion to the roller F', which feeds the log or timber along on the rollers F' F" F" the desired length. The cone-pulley M is then again thrown in gear with t-he wheel K, and the saw fed down to its work.
I would remark that when this rising and falling movement oi' the sawE is not required, the bar G may be moved upward to its fullest extent, and allowed to remain in that position, and used as an ordinary circular saw. This may be preferable when ligh`t or small wood is t-o be sawed. I would further remark that an ordinary reciprocating saw may be driven from the shaft B, to be used when required.
VThe swinging pendent nut'frame H, it will be seen, compensates for the curvilinear movement of the bar C, and prevents the bending of the screw I in the nut.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination ot' the screw I and swinging nut H with the saw-frame G, for feeding or ret-racting the saw, as described.
2. In combination with the aforesaid screw I, swinging nut H, and saw-frame G, the shaft L, wheels K S7 pulleys M Q, and belts P N, all arranged and operating as and for the purposes specified.
