DRAG-SAWING MACHINE.
SPECIFICATION forming part of Letters Patent No. 228,064, dated March 30, 1880.
Application filed January 31, 1880.
To all whom it may concern:
Be it known that I, CLARK HAGERTY, of Killmoreville, in the county of Clinton and State of Indiana, have invented a new and valuable Improvement in Drag-Sawing Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a side view of my improved sawingmachine. Fig. 2 is a transverse section of the same 5 and Figs. 3, 4, and 5 are details.
This invention has relation to improvements in sawing-machines; and it consists in the arrangement and novel construction of the parts of the machine, as will be hereinafter more fully set forth.
In the annexed drawings, the letter A designates the base of the machine, composed of two beams, a, converging at theirfront ends and connected in rear by a brace, I), provided with feet a, designed to take hold upon the ground. The beams a have at their front ends metallic spurs c, that bury themselves in the log and hold the machine stationary.
B indicates a spring-board attached to the base Ajn front, and arranged at an acute angle thereto. This board carries at its rear end a seat, B, and has fulcrumed thereon in front of the seat a vertical vibrating lever, O, that extends up through a longitudinal slot, a, in the spring-board, and is provided at its upper end with a cross-handle, b. This leveris provided at its middle portion under the springboard with a bend, c, to which are pivoted the metallic coupling-straps O, the other ends of which are adjustably secured by means of a pivot, (Z, to the vertically-vibrating treadles D, pivoted at their front ends to the said spring-board at y, and extending to the rear within a convenient distance of the seat. These treadles are connected together by suitable rods y, and work together, and they are each provided with alongitudinal slot, d, (indicated in dotted lines, Fig. 1,) and a series of transverse perforations, e, in order to the ad- 0 justment of the straps O and to the limiting or regulating the throw of the treadles.
E indicates vibrating links pivoted to the beams a at one end, and at the other to the rear bend or offset, 0, of lever 0. These pivots e e are both in rear of the fulcrum e of the lever G, and the links E form with the said lever a toggle-joint connection between the base and spring-board, thus afi'ording great power to throw up the spring-board when the pivots e e and the fulcrum e are brought in line by drawing back upon lever G. The low part of this lever is provided with a deep notch, f, and is finished off with elbow-irons 9, usually of right-angular form, and having each an arm, h, extending to the rear and provided with spaced perforations i, for the attachment of the saw. This is accomplished by means of a bolt, t", extending through said perforations, ,and the pitman F of the saw, in which similar perforations are made. This arrangement allows the vibrating movement of the saw to be varied according to thethickness of the log.
The pitman F is made in two sections, j j, hinged together by their upper edges, and provided with a spring, 8, bridging the recess Z, in which the hinge w is fixed, and preventing the sections from having undue flexibility. This spring is secured at one end to one of the sections, and bears at the other on the other section. I
Upon the under side of thepitman, and extending across the joint of its sections, is a longitudinally-slotted metallic slide-plate, G, sliding 'endwise upon a bolt, a, extending through section j, and adjustably clamped thereto by a clamp bolt, 02. Extending through the section j is a stop-bolt, 0, the lower end of which extends through the slot p of plate G. This plate being secured to one section fixedly, and the stop being fixed in the other section and engaged in the slot of said plate, it is clear that the flexing of the pitman is thus brought within fixed limits.
By loosening the clamp-bolt, adjusting the slide G, and reapplying the said bolt, the degree of flexure may be increased or lessened, according to circumstances.
The sections of the pitinan are held in' line by the cheek-plates s.
The sawing-machine thus constructed drives the saw to out both ways, is self-clearing, and the return stroke is made without effort on the part of the sawyer, owing to the flexing of the toggle-joint connection of the spring-board and base and the vibration of the lever caused thereby.
What I claim as new, and desire to secure by Letters Patent, is-
1. The combination of a base, A, springboard B, lever U, i'nlcrumed in said board, deeply notched at fin its lower end, and having the parallel rearextending arms h, with spaced perforations i, and a saw-pitman, F, extending through said notch and adjustably bolted to said arms in rear of the lever O,substantially as specified.
2. The sawpitman F, composed of the sec tionsjj, hinged togetherat their upper edges, and the spring .9, bridging the joint of the sections and restraining their flexibility.
3. The combination, with the sectional CLARK HAGERTY.
