Description
`reitsh gioire hattet @time I. R. HARMAN, 0F WHITESTOWN, INDIANA, ASSIGNOR TO HIMSELF AND THOMAS J. MEGINNIS, OF THE SAME PLACE.
Letter-s Patent No. 73,000, dated January 7, 1868.
IMPRQVEMENT 1N swine-MACHINES.
TO ALL WHOM IT MAY CONCERN:
Be it known that `I, I. R. HARMAN, of Whitestown, Boone county, and State of Indiana, have invented :t new and useful Im}.' 1ovcment is Drag-Saws; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure 1 is a perspective view,
Figure'2 is a side elevation, and
Figures 3, 4, 5, and 6,-sections in detail.
The nature of my invention consists in the use of an eccentric-cam, in combination with a. movable centre, at one end of the shaft, with slides at the other end of the same shaft, with friction-rollers combined with said shaft, as hereinafter fully described.
To enable others skilled iu the art to make and use my invention, I will proceed to describe its construction and operation. y
In the construction of my invention, (numerioals are used instead of lettersvof the various parts, and the same figures designate like parts in each of' the drawings,) iig. 1, the frame of the machine; fig. 2, the adjustable guide, which works on a pivot, aattaching it to portion of the frame at the rear end, and having at the front end attached a sta-ple, slipping down over a small post of the frame, to keep it in place in rising and lowering in the eet of sawing. Figs. 4, 5, and 6 form an eccentric, in which a friction-roller, attached to the end ofthe 1 saw-guide, operates, to give a vibrating motion to the saw, and by which means a reciprocating inotion is obtained in running the saw. Figures 7 7 are slides, in which the two friction-rollers play, which are'attached vte the front end of the saw-guide. Figure 8, the saw. Fig. 3, thc'reciprocating saw-guide, to which the saw is attached, the rear end of which operates on a cam, te obtain the reciprocating mot-ion of the saw. 3, the pston-rod, connecting guide 3 to the crank-wheel. 10, the crank or fly-wheel. 11, the bevel-gear wheel,- on the same shaft with the ily or crank-wheel. Figure 9, the drivingwheel, to which the power is attached bya crank or otherwise. In figs. 3, 4, 5, and 6, in Drawing III, 13 is the spring to replace the cam 5. 14 14, the friction-ro1lers, ope-rating on the slides 7 7, for guiding the saw, and 15 the friction-roller operating on cams 4, 5, and G, to produce reciprocating motion in running the saws. v i
In the operation of my invention, motion is given to it by means of the crank or other power, which is communicated to the saw-guide (iig. 3) by means of the piston-rod 3', causing it to move forward the length of the piston-rod, being guided in its course by the friction-rollers working in the slides 7 7, and the cam-slide 6'6, and the spring-cam, marked 5, as friction roller 15, in running forward, descends the inclined plane on spring-cam 5, and between it and the upper cam-slide G, until the length of the stroke Ibrings it to the lower end of the spring-cam, which is then relieved of its weight, und the roller 'rests on the lower cam-slide 4, allowing the spring-cam to be operated by the spring 13, thus changing its relative position to the lower and upper cam-slides 4 and 6. The roller tlicn, in the backward stroke of the piston, rests on the lower slide until the length of the stroke is made, causing the spring-cam toA oscilliite as the roller nsecnds the inclined plane of the lower cam-*slide until it rises on a line parallel to the top side of the spring-earn, when the said cam is again operated on by the spring 13, pressing it` down to receive the friction-roller 145 in again making its forward stroke, as before described, thus operating the saw, und givingto it the motion required. 4
It will be seen that'by means of the staple attached to the guide 2, the saw is raised and lowered to suit the size ofthe piece of timber to be sawed.
Having thus fully described the nature 'of my invention, what I desire to secure by Letters Iatent, is-
'lhe combination of the movable centre 15 with slides 7 and 7, 4 and 6, and eccentric-cam A5, and spring 13,
all constructed and operating substantiallyas set forth.
' I. R. HARMAN.
