SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 788,528, dated May 2, 1905.

Application filed February 11, 1905. Serial No. 245,277.

To all whom it may concern.-

Be it known that I, JOHN FAFRI, a citizen of the United States, residing at Goble, in the county of Columbia and State of Oregon, have invented certain new and useful Improvements in Saw-Handles; and I do declare the following to be a full, clear, and exact description of the invention, 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 handles for crosscut-saws; and the object of the invention is to produce a simple and efficient apparatus of this nature which may be easily applied to a saw and so arranged that the handle may be adjusted for convenience in operating the saw and in such a manner that said handle may be held vertically or transversely.

The invention consists, further, in various details of construction and in combinations and arrangements of parts,which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings Figure 1 is a perspective View showing my device as applied to a saw. Fig. 2 is an enlarged perspective view showing the handle adjusted at right angles to the position shown in Fig. 1. Fig. 3 is a detail perspective view showing one of the parts of the device detached. Fig. 4 is a detail perspective view of the part of the device which engages the end of a saw and which receives the part illustrated in Fig. 3, and Fig. 5 is an enlarged detail view in elevation of the part of the device which engages the saw.

Reference now being had to the details of the drawings by letter, A designates a saw of the usual cross-cut form having apertures therein for the reception of the handle-attaching means.

B designates a screw having a head B,

which has two slots D and I), which intersect each other, as shown clearly in Fig. 5 of the drawings. Each of said slots has, respectively, lugs (Z and cl projecting from the opposite walls thereof and adapted to engage the holes of a saw, which in standard makes of saws are a uniform distance apart. Referring to Fig. 5 of the drawings, it will be seen that a portion of the side wall of each slot is inclined, as at E, while the remaining portion of the same side of the slot, as seen at E, is parallel with a central line through the slot. This inclined portion of the slot is for the purpose of allowing a saw to be inserted intermediate the adjacent lug upon the opposite wall of the recess in such a manner that the lugs will engage the holes in a saw from opposite directions when the saw is turned so that its opposite faces will engage the faces of the portions of the slot from which the lugs project.

K designates a bar having a handle K upon one end thereof, and said bar has a recess N, adapted to receive the square outlined head of said screw in the manner shown in Fig. 2 of the drawings. Said bar has a longitudinal groove O formed in one face thereof adapted to receive the end of a saw when the handle is adjusted to said saw.

Q, designates a nut, the bore of which is provided with threads which fit upon the shank portion of the screw B, and said nut has wings Q, for convenience of engagement with a spanner or other tool for the purpose of turning the nut against the face of a bar K in the manner shown in Fig. 2 of the drawings, whereby the opposite face of said bar K may be held securely against the end of a The outer threaded end of the screw B is fitted in a threaded boss T upon a plate T, which is held to one side of a handle S, and S designates a concaved plate, which is held to a portion of the handle S diametrically opposite the plate T, said plate S being held to the handle S by means of a screw 8*, which passes through the handle and engages a threaded-aperture in the end of the screw B.

In adjusting the device to a saw the lugs in one of the slots in the head of the screw are inserted in the holes near the end of the saw, and when the apparatus is adjusted in the manner shown in Fig. 1 of the drawings the handles K and S are in the same plane and in the plane of the broad face of the saw. To hold the screw securely in place when the lugs engage the apertures, the nut Q is tightened against the bar K, causing the same to bear frictionally against the end of the saw, the latter being held from movement by the lugs, thus securely clamping the apparatus in place.

When it is desired to turn the handle S at right angles to the position shown in Fig. 1 for convenience in sawing or for any other purpose, the nut Q, may be unscrewed and the head of the screw detached from the saw and the other slot in the head of the screw adjusted to the saw with the second set of lugs engaging apertures in the latter, after which the bar may be pushed over the head of the screw and made to engage the end of the saw, after which the nut Q may be tightened against the bar and cause the saw to be securely clamped.

It will be observed that while I have shown the bar K in the same position with relation to the saw in Figs. 1 and 2 the bar K may be adjusted at right angles to the position shown in Fig. 1, if desired, as the saw-engaging face of said bar is provided with intersecting grooves O and 0.

While I have shown a particular form of apparatus illustrating my invention, it will be understood that I may vary the details of the same, if desired, without in any way departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is*

1. An attachment for saws comprising a screw having a head with intersecting slots, lugs projecting from the opposite walls of said slots and adapted to engage apertures in the saw, a bar having a groove upon the face thereof and adapted to fit over said head, a tightening-nut mounted upon said screw and adapted to clamp said bar against the end of a saw,

and a handle fitted to the end of said screw, as set forth.

2. An attachment for saws comprising a screw having a head which is provided with intersecting slots, lugs projecting from the opposite walls of said slots, a bar adapted to fit over the head of said screw and provided with intersecting grooves upon one face thereof for engagement with the end of a saw, a nut mounted upon said screw and adapted to engage said bar and hold the same against the end of a saw, a handle upon said bar, and a handle fixed to the end of said screw, as set forth.

3. An attachment for saws comprising a screw having a headed portion provided with intersecting slots, lugs projecting from parallel portions of opposite walls of each slot, the portion of the wall opposite each lug of the slot being inclined, a bar having an aperture adapted to receive said head and having intersecting grooves in the face thereof, adapted to receive the end of a saw, a nut mounted upon said screw and adapted to bear against said bar, and a handle fixed to the end of said screw, as set forth.

4. An attachment for saws comprising a screw having a headed portion provided with intersecting slots, lugs projecting from parallel portions of opposite walls of each slot, the portion of the wall opposite each lug of the slot being inclined, a bar having an aperture adapted to receive said head and having intersecting grooves in the face thereof, adapted to receive the end of a saw, a nut mounted upon said screw and adapted to bear against said bar, a handle secured to said screw, and concaved plates fastened to opposite sides of said handle, as set forth.

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

JOHN FAFRI.
