DRAG-SAW.

SEEGIFIGATION forming part of Letters Patent No. 660,177, dated October 23, 1900.

Application filed February 7, 1900. Serial No. 4,915. (No model.)

' States, residing at Pond, in the county of Benton and State of Arkansas, have invented certain new and useful Improvements in Drag- Saws, of which the following is a specification.

Our invention relates to improvements in drag-saws, and pertains to a supporting and actuating mechanism wherebya single operator can do the work which usually requires two, all of which will be fully described hereinafter and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of ourinvention, showing it in operative position upon a log. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged side elevation of the inner end of the supportingbeam, showing the depending hooks for attaching the beam to the log.

The object of ourinvention is to provide a simple and cheap mechanism which is adapted to have attached thereto an ordinary dragsaw, the mechanism so constructed that one person can operate the saw, the machine being constructed to actuate the saw in one direction, thus enabling one operator to perform the work which has heretofore usually.

required two.

Referring now to the drawings, A indicates -a beam which is provided at its inner end with a longitudinally-extending short block B. Pivoted between this block B and the adjacent portion of the beam A are the two depending hooks at, having their lower hook ends extending inward and adapted to be engaged with a log 0, as shown in Fig. l. Projecting upward between this block B and the beam A at a point intermediate the ends of said block is an eye b, to which one end of a hook D is attached, the opposite end of the hook being turned laterally and sharpened, as shown at c. This hook is adapted to extend at right'angles to the beam A and longitudinally the log 0 and to be driven into the said log. For the purpose of bracing the beam A against lateral movement and servingas a further means of connecting the beam to the log a rod E is provided, which has its outer end pivotally connected with the beam A at a point preferably beyond the center thereof,

machine is then ready for operation.

the inner and free end of the rod extending downward and sharpened to form a spike or hook adapted to be driven into'the log, as shown in Fig. 1, and thus serve to brace the beam against lateral play and serve to hold the same steady, as will be readily understood. Depending from the outer end of this beam is a supporting-leg F, adapted to rest upon the ground and to support the outer end of the beam. Intermediately pivoted to the opposite side of the outer end of the beam A from the said depending supporting-leg F is a lever G, the lower end of the lever having a coil-spring H connected therewith, the opposite end of this coil-spring adapted to be connected with one end of an ordinary dragsaw I, the opposite end of the drag-saw having the usual operating-handle J. The opposite and upper end of the lever G is connected by means of a rope, cable, or chain K with the free end of a coil orconvolute spring M, the said spring having one end rigidly connected with the beam and its opposite end,

as before stated, connected with the,upper end of the intermediately-pivoted lever G.

In operation the inner end of the'beam A is connected with the log by means of the hooks CL and c and braced in respect thereto by the rod E. The saw is then connected with the spring H, as clearly shown. The The operator draws the saw toward him by the handle J, and the spring M serves to draw it in the opposite direction, the same as an operator would do. The spring H serves to hold the saw to its work in the same manner as the saw would be held down by an operator having hold of the end of the saw to which the said spring is attached.

By means of this construction one person moves the saw in one direction and the spring M in the opposite direction, the said spring serving the same purpose as a second person, thus enabling one operator to perform the work which usually requires two to perform.

Our saw is here shown in connection with a log lying upon the ground, and hence in a horizontal position; but it will be readily understood that the beam can be attached to a tree and the saw then be in a horizontal position for the purpose of felling a tree. In this instance the supporting-leg will be folded parallelthe beam, or when the machine is not in operation it will be correspondingly folded.

The supporting-leg, when the machine is being used in connection with small logs, serves as a means to support the beam and also to prevent the rolling of the log.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-- 1. A drag-saw comprising abeam carrying at one end means for attaching it to the object to be sawed, and at its opposite end a supporting member, a lever arranged transverse the said beam, and intermediately pivoted to its outer end, one end of the lever projecting beyond the beam, and a downwardly-extending spring having one end connected to the projecting end of the lever and its opposite end connected to the said saw, and a spring connected to the opposite end of the said intermediately-pivoted lever, substantially as described.

2. A drag-saw comprising a beam A having one end resting directly upon the object to be sawed, the said end of the beam having separated downwardly-extending hooks, and a horizontally-extending hook situated at a point intermediate the said down wardly-extending hooks, a rod E having one end connected to the beam intermediate its ends, and extending diagonally therefrom, and having a hook at its free end for attachment to the object being sawed, a saw, the outer end of DAVID ADKINS.
