OLOF OHLSON, OF VANCOUVER, WASHINGTON.
SAW-HANDLE.
Application filed June 29, 1909, Serial No. 505,098.
To all whom it may concern:
Be it known that I, OLOF OHLSON, a citizen 0f the United States, residing at Vancouver, in the county of Clarke and State of WVashington, have invented certain new and useful Improvements in Saw-Handles, of which the following is a specification.
This invention relates to handles for cross cut saws; and its object is to provide handles of this class with improved devices for readily attaching or detaching the same with a saw-blade and also afford a guard which will protect the operators hands from becoming cut by the saw teeth.
The invention consists in the novel construction and adaptation of parts, as will be hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a side elevation of an embodiment of my invention applied to a saw-blade. Fig. 2 is a perspective view of the handle proper. Fig. 3 is a similar view of the handle securing member.
The reference numeral 5 designates the shank of the handle having at one end a sleeve 6 for the handle bar 7 and adjacent to the other end is a boss 8 provided with an aperture 9 to accommodate the securing member. From said shank are laterally extending spaced lugs 10 and 11. The lugs 10 are each provided with a notch 12 in their top faces to furnish seats for the back edge of a saw-blade, and, for a like purpose, similarly disposed notches 13 are provided in the lugs 11. The aforesaid notches of the respective lugs are arranged to be in alinement and are offset from the axis of the shank 5. The saw-blade, represented by 14:, Fig. 1, is secured in either pair of said notches by the above mentioned. securing member, which is comprised of a rod 15 which is screw threaded at one end. and is provided at its other end with an offset wing 16 which extends in an oblique direction from the axis of the rod and of a length from an intermediate shoulder 17, suflicient to extend beyond the points of the sawteeth when such shoulder is seated within a saw-gullet. Said threaded end of the rod Specification of Letters Patent.
Patented Oct. 11, 1910.
Renewed June 20, 1910. Serial No. 567,975.
is passed through the aperture 9 of the handle-bar to receive a winged nut 18 therebeyond.
In connecting a handle to a saw, the wing 16 of a securing member is inserted through a saw-gullet from one side and is then swung to bring the wing against the blade face, as shown in Fig. 1, whereupon the nut 18 is manipulated to cause the shoulder 17 being drawn hard against the blade and the latter into the selected notches of the handle bar. To detach the handle, the nut is first turned to loosen the securing member which is then rolled over to disengage the shoulder 17 from the saw and bring the wing into position to pass unobstructedly through the gullet wherein the shoulder was engaged.
The advantages of the invention reside principally in the facility afforded by the securing member with which the handle may be disconnected from the saw-blade as when it is necessary to withdraw the blade from a cut as the tree is being felled in toppling, and also in the protection alforded by the wing to guard the operators hands from becoming lacerated through contact with the points of the saw-teeth should the handle slip from his grasp when being operated;
lVhat I claim, is
A saw handle comprising a shank provided at one end with a sleeve and at its other end with an-aperture, a handle bar connected to said sleeve, a securing member projecting through the aperture and provided at one end with a shoulder adapted to engage the wall of a saw gullet for coupling the end of a saw blade to the shank, said member further having a wing projecting beyond said shoulder and directed obliquely with respect to the axis of the said member and extending toward the said bar to protect an operators hand, and means carried by the member and engaging the shank for maintaining said member in operative position.
