COMMODORE P. HELLYER, OF RUSSELL, IOWA.
DRAG-SAW MOTOR.
SPECIFICATION forming part of Letters Patent N 0. 660,955, d t d O t b r 30, 1900.
- Application filed June 4, 1900- To aZZ whom it may concern.-
Be it known that I, COMMODORE P. HELL- YER, a citizen of the United States, residing at Russell, in the county of Lucas and State of Iowa, have invented certain new and use ful Improvements in Drag-Saw Motors, of
which the following is a specification.
My invention relates to improvements in drag-saw motors, all of which will be fully described hereinafter and particularly pointed out in the claim.
The object of myinvention is to provide a mechanism by means of which a drag-saw can be rapidly operated and by means of which it can also he raised and lowered in respect to the object being sawed.
In the accompanying drawings, Figure l is a side elevation of a motor embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation looking at the opposite side from that shown in Fig. 1.
Referring now to'the drawings, A is a rectangular frame in which my mechanism is supported. Journaled in the front end of the frame is a horizontal shaft B, carrying at one end a crank G, to which one end of a pitman D is pivotally connected. The opposite end of this pitman D is pivotally connected to an operatinglever E at the point E, which is intermediate the ends of the said lever E. From this it will be seen that when the upper free end of the lever E, which has its lower end pivotally connected at the point F, is reciprocated the shaft B is rotated.
Secured to the shaft B is a pulley G, around which passes a belt or chain H, the said belt or chain H passing also around a smaller pulley I, which is fast to a crank-shaft J. This crank-shaft- J has a crank K intermediate its ends and carries a balance or fly wheel L.
Projecting verticallyand situated at a point intermediate the front end of the frame A is a suitable standard M, and having one end connected with the said standard M is a bar N, the opposite end of the bar N being connected with the frame A. AleverPisintermediately pivoted to the bar N near its front end, and connecting the front end of this lever P and the crank K of the shaft J is a pittnan Q. Pivotally connected with the oppo- Serial No. 19,039. \llo model.)
site end of the lever? is a saw carrying pitm-an R, the outer end S being suitably constructed to receive the saw T. This saw-pitman R consists of two parallel separated bars situated at opposite sides of t he vertical standard Maud also at opposite sides of a vertical rod a. serves as a means for raising and lowering the saw-pitman R, is pivotally connected with a lever b, the opposite and inner end of the said lever being pivotally connected in any suitable manner with the frame A.-From this description it will be seen that the sawpitman R rests upon the lever b and is supportedthereby, while it is guided in its move- The lower end of this rod a, whichtnents through the medium of the standard M and the bar a. The upper end of the bar a. is pivotally connected with the outer end of the intermediately pivotaliy supported lever 0, the said lever 1; serving as means for raising and lowering the lever 12, and hence in turn raising and lowering the saw-pitinan R, and consequently the saw.
The handle end of the lever 0 extends to the rear portion of the machine, whereby the operator can oprratethe lever E with one hand for causing the reciprocation of the saw and wit-l1 the other (preferably the left hand) grasp the hand end of the lever c for raising and lowering the saw through the medium of the saw-pitman R, as before explained.
For the purpose of assisting in guiding the saw a lever 61 has its inner end pivotally con-' nected with the standard M and has its outer end provided with a downwardly-projecting fork e, which straddles the upper edge of the saw T. This guiding-lever d passes loosely through a loopf upon the rod a.
From this description it will be seen that the operator can cause a rapid reciprocation 'of the saw with one hand, while with the other hand he can regulate the engagement thereof with the object being sawed.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
In a drag-saw the combination with a saw and a reciprocating mechanism operatively connected therewith, of a lever b for lifting the saw, a lever c operatively connected with the lever 19 through the medium of the verti-.
ner end pivotnlly connected and it souterend in presence of Lwu witnesses.
provided with a fork engaging t-he top edge COMMODORF P HFTTYFR of the saw, the bar (1 being intermediately I J J J J but slidably connected with Ihe bar a, whereby when the saw is lifLed the guiding-bar d is also lifted, substantially as described.
