HANDSAW- Specification of Letters Patent.

JOINTER.

Patented Feb. 26, 1907.

Application filed September 7,1906. Serial No. 333,703.

To all whom it may concern; I

Be it known that I, ALPHEUs P. HALL, a l citizen of the United States, residing at Graysville, in the county of I/Vhite and State of .Illinois, have invented certain new and useful Improvements in I-Ianclsaw-Joi11ters; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in handsaw ointers, and comprises a simple and efficient device of this nature whereby the cutting edges of teeth may be conveniently trued.

The invention comprises various details of construction and arrangements of parts, which will be hereinafter fully described, and then specifically defined 1n the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a perspective view showing the application of my invention. Fig. 2 is a cross-sectional view through the device, showing a file held thereto; and Fig. 3 is an enlarged detail perspective view of the in vention.

Reference now being had to the details of the drawings by letter, A designates a jointing device which is made of a single piece of metal having one end bent at an angle at A and having a lateral extension A and again bent at an angle with a downwardlyextend ing flange A forming a partial closure to receive a fileB, which rests upon the inturned lips O. Projecting from the body portion of the jointer are the lugs D, which extend at right angles therefrom and are adapted to contact with the face of a saw-blade E. The lower end F of the jointer is bent at an angle parallel to the lugs D and is adapted to cooperate with the lugs D to hold the saw parallel with the body portion of the jointer.

In adjusting the device for operation a file is placed in the position shown in the drawings and the device placed against the face of the saw-blade, with the lugs and bottom of the device against the face of the saw as guides. By moving the file lengthwise back and forth, keeping the guides in contact with the saw, -it will be noted that the teeth will be truly jointed.

By the provision of a device of this nature it will be observed that a simple and eflicient combination file-holder and gage is provided,

made, preferably, of a single piece of metal,

and by which the cutting edges of teeth may be accurately and quickly jointed.

What I claim is A saw-jointing device made of a single piece of sheet metal, the upper portion of which is laterally bent forming an extension A with a downwardly-bent flange A laterally-projecting lugs C struck up from the opposite edges of the shank portion of the device, with their upper surfaces in a plane coincident with the end of said flange A and adapted to hold a file, lugs D also struck up from the opposite edges of the device and projecting slightly in advance of the lugs O and parallel thereto, the lower end of the device being at right angles, as shown and described.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
