To all whom it may concern:

Be it known that I, FRANKLIN H. TURNER, a citizen of the United States, residing at Sattley, in the county of Sierra and State oi California, have invented new and useful Improvements in Combined Saw Olamps and Sets, of which the following is a specication.

This invention relates to a combined saw clamp and set, and the piu-pose of the same is to provide a device of this class which can be quickly set up for use in woodland tracts where a cross-cut or analogous saw is used for felling trees and capable of beingsupported on a stump or other object and operative to hold a saw-blade dining a sharpening operation.

The invention consists in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawing, Figure l is a perspective view of a saw-clamp, embodying the featiues of the invention, and shown applied in operative position and as holding a saw-blade. Fig. 2 is a top plan of the clamp, and Fig. 3 is an end elevation of the clamp.

Similar numerals of reference are employed to indicate con'esponding parts in the views.

The numeral l designates a supporting strip or bed, having pairs of openings 2 arranged therein near opposite extremities, and flanges 21 arranged adjacent its side edges to adapt it for holding tools. The bed, at opposite sides, has securing chains'or analogous devices 3 attached thereto and provided with terminal hooks 4, for securement in a stump or other object on which -the supporting strip or bed l is disposed. Movably extending through the openings 2 are uprights 5, having clamping jaws 6 secured to their upper extremities and movable transversely over the supporting strip or bed l. Extending transversely inward through one side edge of the supporting strip or bed l, are clamping screws 7, to engage one set of uprights 5 and regulate the adjustment of the latter, and the jaw 6 carried thereby, in relation to the remaining jaw and uprights to accommodate variations in the thickness of saws. Movably attached to the lower ends of the uprightst 5, with which the screws 7 engage, are clamping levers 8, one on each upright, the said levers having inner enlarged or cam heads 9, to engage the inner edges of the uprights opposite those to which said levers are attached. The uprights with which the cam heads 9 of the levers 8 engage are disposed at one side of the uprights carrying said levers, as shown by Fig. l, and by causing the said lever heads to engage the uprights, as explained, the one jaw connected to the lever carrying uprights is firmly clamped against the saw-blade that may be disposed between the jaws. This operation of clamping the jaws is rendered practical bythe use of the set screws 7 which provide means for obstructing the outward movement of the uprights carrying the levers. In operating the levers 8 to set up the clamping action of the jaws just explained, said levers are pulled upwardly, and in releasing the saw-blade, a reverse movement is given to said levers.

To adapt the clamp for holding narrow saw-blades and projecting the teeth of the latter above the upper edges of the jaws, openings 10 are formed in the said jaws at suitable elevations to removably receive pins Il. The upper edges of the jaws G are curved to conform to the longitudinal curvatiue of the teeth of a sawblade in order that the latter may be equally exposed throughout the length of the blade held between the said jaws.

To support a saw-blade in horizontal position to permit its teeth to be set, arms l2 are pivotally mounted upon the supporting strip or bed near its opposite extremities, said arms being adapted to be swung inwardly when not in use, as disclosed in Fig. 2 of the drawings, and outwardly to project their free ends beyond one side edge of the supporting strip or bed when desired for use, as disclosed in Fig. 1 of the drawings. A saw set I3 is pivotally mounted upon the supporting strip or bed at a point centrally between the arms and is also adapted to be swung inwardly when not in use and outwardly to position its free end beyond the side edge ofthe supporting sti-iper bed when desired for use. The under surfaces of the outer portions of the arms and saw set are removed, as at 14, to permit their free ends to be swung over the flange 2L when moving the arms and saw set into position for use. The saw set is provided with a downwardly and inwardly inclined working face l5 and with an adjustable gage 1G. The upper surfaces of the inner-portions of the arms are removed, as at I7, to permit a saw-blade to be moved thereon when setting its teeth without injury to the teeth.

The improved device will be found exceptionally useful, particularly in forests or woodland tracts where it is not always convenient to have a bench or other supporting means for a clamp. It will be understood that changes in the proportions, dimensions, and minor l details may be resorted to without in the least departing from the spirit of the invention.

Having fully described and illustrated the invention, what I claim is:

1. A saw the bed to a clamp comprising a bed, means for securing stump or other support, said bod provided jecting through the slots, :1nd means for spreading the 1 0 lower ends of the uprights to chimp the jaws.

In testimony whereof, I aiiix my signature in presence 0f two witnesses.

FRANKLIN H. TURNER.
