J. B. SWEETLAD, OF PONTIAC, MICHIGAN.
Letters .Patent No. 61,893, dated February 5, 1867. l
IMPROVEMENT IN SAWING MAGHINES. Y
-.ski-
TO ALL WHOM IT MAY CONCERN:
Be it known that I, J. B. SwEETnANm'of Pontiac, in the county of OaklandandlState of Michigan, have Ainvented certain new and useful Improvements in Sawing'Machines, and do herebydeclare that the 'following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon.
In the drawings, A A' A" represent three triangular metallic frames, which are placed at a suitable distance apart, and secured at their bottoms to a base, B.v These frames are secured together by means ofy twoside plates u u, which are bolted fast to the said frames. C represents a shaft, which .passes throughproper openings made to receive it in the frames A and A. One `end of this shaft is provided with a screw-thread, andthe other` end is made square to receive upon it a clutch, E. This shaft is provided near one end with a balance-wheel, R, and near the other with a circular` saw, I. The saw Ilis held in position by means of an annular plate or collar, e. J represents a sleeve or nut, with a thread cut on itsinside to fit the thread upon the end of shaft C. An auger, K, is secured in one end of sleeve J by means of a set-screw, c, which passes, through said sleeveso as to press against the auger. When the sleeve J is screwed on the end ofthe shaft C its inner end presses against the plate or collar e, and thus serves to stationy the sawI firmlyupon the shaft. D represents a shaft, which is secured between the framesvA and A", and operated as will` be described. One end of shaft D passes into clutch E, and is there stationed by means of a set-screw, a the other end' of said shaft Dis provided with an opening into which passes the tapering end of a screw, G. The screw G'Ipasses through a proper opening with thread in it in the upper end of frame A. F represents a sleeve, which passes over Vthe shaft D, and which is provided witha large wide screw-thread upon its outside. This sleeve is stationed on 'Y the shaft D by means ofV a. clutch, d, which is provided with a set-screw, b. The screw Gr is provided with two nuts, `7i and 2', one on each side of frame A, for the purpose of statiouing said screw in any desired position. Hrepresents a wheel, secured upon a shaft, S, which said shaft lies crosswise of the frames with its bearings upor the side plates u u. This wheel H is provided upon its periphery with a series of pins, which said pins are ih turn providedwith a series offriction-rollers, g g. These pins, with their rollers, are situated at regular intervals apart, and catching in the thread upon sleeve F serve to give motion to said sleeve, and consequently to the shafts D and C. vZ are a series of lugs upon the wheel H, which are situated Vbetween the pins. The shaft S is provided with a. crankhandle, which serves to give motion to the operating devices hereinbefore described. M represents a saw-buck, which is pivoted to the frames A A near their bottoms, and which swings toand from the sawIupon its pivots. This buck is provided with two guard-bars P P; the ends of said bars nextto the frames being formed so as to catch against one of the legs of the frames when the buck is pushed from the saw, so as to allow said buck to retreat only so far, or a given distance out of roach of the saw. O represents a spring, which is secured to one of the side plates u, and which serves to press the buck away from the frames. The buck is pressed toward vthe saw by the operator, and away from it by the spring O. N represents a forked device upon the upper end of the buck, to hold the wood to be sawed. L represents a platform supported upon arms projecting up from the plates u u, which serves to sustain anything to be operated 'upon by the auger K. 4
In using this machine for sawing wood, the timber is placed in the buck and pressed up toward the saw by the hand of the operator. By means of the handle T the wheel H is set in motion, which in turnA gives motion to sleeve F, shafts D and .0, and thus to the saw I. The samedevices of course give motion to the auger.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- The wheel II and worm-sleevevF, when used in combination with the clutch d and coupling E for revolving the shaft D and saw I, all constructed and operating substantially as described.
In testimony that I claim theiorcgoing, I have hereunto set my/hand and seal this 27th day of December, 1866.
