SAW-HANDLE.

Specification of Letters Patent.

Patented Feb. 3, 1914:.

Application filed June 27, 1912. Serial No. 706,214.

To all whom it may concern:

Be it known that I, HERMAN A. J. THRUN, a citizen of the United States, and a resident of Ellson, in the county of Pine and State of Minnesota, have invented certain new and useful Improvements in Saw-Handles, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in handles employed in connection with saws especially used in sawing logs and large timbers, and comprises a handle arranged to be grasped by one hand, and the primary object of my invention is to provide a one man saw handle, of a simple and inexpensive nature and of a compact and durable structure, arranged so that the operator can firmly and conveniently grasp the handle in operating the saw.

IVith these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the-invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1, shows a side velevational view of a saw handle embodying my invention, secured to the end of a saw blade, a fragmentary portion of which is shown. Fig. 2, shows a top view of the handle. Fig. 3, is a section on line 3, 3 of Fig. 2.

In my present invention I provide a 'handle arranged to be secured to that class of saws known as a one man saw, used to saw logs and timbers. As these saws are often used in winter by operators having their hands protected by thick mittens, I embody a handle which can be conveniently grasped by the gloved hand, so that the saw can be firmly and conveniently held and accurately guided.

In the drawings the letter. S indicates a fragmentary portion of a saw blade to which the handle is secured. The saw handle proper includes a slotted head 1,'having suitable apertures to receive the securing bolts 4, by means of which the handle is secured to the saw blade in the manner shown in Fig. 1. Extending from the upper end of the slotted head is the crooked shank 2 having the base 3, from the face of which is continued the reduced tapering stem 7, which is square in cross section, and ends in the screw 17 'shown in Fig. 3. The base 3 is oblong and is provided with a circumscribing flange 8, extending from the face of said shank. Securely held to the tapering stem 7 is a flat handle 10 preferably made of hard-wood, which has one end 9, reduced so that this end will iit behind the flange 8, in the manner shown in Fig. 3, to securely hold the handle at that end, and prevent splitting of the same. The opposite end 11, of the handle is also reduced. As shown in Fig. 3, the socket within the handle is of a size to snugly fit the reduced stem 7.

In order to hold the handle 10 to the tapering stem I employ an apertured oblong cap 13, having the circumscribing flange 12 to form a socket as it Were, within the smaller end of this cap, to receive the reduced end 11, of the handle 10, thus also preventing the splitting of the handle at this end. As shown the cap .gradually flares outward so as to form a convenient base to receive the operators hand and prevent the same from slipping ofi' the handle 10. The reduced end of the stem 7, passes through an opening within the cap 13, which has a nut socket 14, within its outer face to receive the nut 16. In the drawing, a washer 15 is shown as interposed between the cap and nut. The handle is held at an angle extending obliquely to the head 1, so that the saw can be conveniently used.

A handle constructed according to my invention will not chill the hand of the operator, and is simple and inexpensive in construction and both durable and efiicient in operation. A handle embodying my invention may further be secured to any ordinary manually operated saw.

Having thus described my said invention what I claim as new and desire to secure by United States Letters Patent is:

A saw handle including a slotted apertured head from one end of which extends a crooked shank from which is continued a reduced tapering stem held oblique to said head, a circumscribing flange extending from the end of said shank, said stem being square in cross section and ending in a screw, a flat handle having a square socket to receive said stem, one end being reduced to fit behind said flange, the opposite end of said handle also being reduced, an apertured oblong cap having a flange to receive said last mentioned reduced handle end and gradually flaring outward from said flange with a nut socket in its outer face, the reduced end of said stem passing through said cap aperture, and a nut to hold said cap to said stem and handle, as and in the manner set 10 forth.

In testimony whereof I alfix my signature, in presence of two Witnesses.
