Laura CBcprZc/Znd. I (I'M r Patented Oct. 24, 1944 UNITED STATES PATENT OFFICE Lauri C. Barland, Leicester, Mass, assignor; to Parker Manufacturing Company, a corporation of Massachusetts Application July 23, 1942, Serial No. 451,989

2 Claims.

This invention relates to tool handles and the object is to provide an improved construction for mounting a thin blade, such, for example, as that of a keyhole saw, in a handle, the body of which may conveniently be formed of wood.

My invention will be well understood by reference to the following description of an illustrative embodiment of the invention shown in the accompanying drawing as applied to a wooden handle for a keyhole hack-saw. In this draw- 111g:

Fig. 1 is a side elevation of the complete'saw;

Fig. 2 is an end view on a larger scale showing the handle as seen from the right of Fig. l with the blade omitted;

Fig. 3 is a section on the line 33 of Fig. 1;

Fig. 4 is a plan of the blade-retaining fitting at an intermediate tage in its manufacture;

Figs. 5 and 6 are a side elevation and a top plan view respectively of the fitting; and

Fig. '7 is a section on the line 7-1 of Fig. 4.

The construction shown in the drawing embodies a handle I suitably shaped from wood and kerfed completely across one I end, as best seen in Fig. 3, to provide opposed arm II defining between them an opening or slot into which the blade l2 may enter and wherein it is held and positioned by a suitable metallic fitting.

The preferred form' of this fitting shown in the drawing is constructed from sheet metal, the partly formed blank being shown in Fig. 4, and it comprises two channel plates each having a web I4 and flanges IS, the two webs being connected by integral bridge portions l8 adjacent the flanges. The partly formed blank shown in Fig. 4 may be bent along the lines of connection of these bridges to the form shown in Figs. and 6 providing a structure wherein the two channel plates are spaced by the integral connection provided by the bridges 18, as seen in Fig. 6, which structure may be slid into the kerf in the end of a handle H] between arms II with be provided on the fitting at a location remote from the bridges. Herein (see Figs.'7 and 6) portions of the plates are shown upstruck to form the webs of the plates against the sides of the kerf and the flanges I6 fitting over the upper and lower sides of the arms ll, thus locking the fitting against angular movement relative to the handle.

As best seen in Fig. 2, the bridges it hold the plates I4 in spaced relation and also define between them a vertical slot into the blade which may he slid longitudinally, the edges of the blade being received with a slight clearance between the stops provided by these bridges.

To further position the blade against excessive angular movement, means for that purpose may pairs of inwardly facing bosses 28 adjacent the inner ends thereof, which pairs are vertically spaced a distance slightly greater than the width of the blade l2. While the bosses oppose one another, preefrably they do not normally make contact for a reason. hereinafter set forth, but they overhang the edges of the blade above and below in the manner shown in Fig. 3 to aid in the positioning of the same. 1

To secure the fitting to the handle body l0 and to retain the blade against longitudinal withdrawal, a screw 22 is provided. One of the plates M has an opening 24, which may be formed with an outwardly projecting lip 26 to provide a greater depth of metal, and which is tapped to receive the screw. One side of the handle body l0 has a hole 28 which registers with the opening 24 when the parts are in position. The body of the screw 20 is received in the opening 23 in the handle and locks the fitting to the same when the screw is entered into the tapped hole while the end of the screw, projecting beyond the plate l4, bears against the blade l2 in the manner of a set screw to secure the same. The

other plate l4 may be cut away to provide a relatively large opening 30 opposite the location of the screw to permit the blade to be flexed into the same under the pressure of the set screw, as illustrated in Fig. 3, to increase the effectiveness of the binding action.

The shallow lip 26 about the opening 22 is received in the hole 28. Not only may the arms H of the wooden handle be sprung somewhat when the fitting is entered therebetween, but since, as described, the bosses 29 do not make contact but have a slight clearance as illustrated in Fig. 6, the sides of the fitting may be flexed toward one another to facilitate the insertion of the fitting with the lip 26 sliding along one face of the kerf until it reaches the position of the hole 26.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, as is in fact clear in several matters from the description itself. Reference is to be had to the appended claims to indicate those principles of the invention exemplified by the particular embodiment described and which I desire to secure by Letters Patent.

I claim:

1. A fitting for mounting a blade in a kerfed handle comprising a pai of channels having closely spaced Webs to be received in the kerf and their flanges directed outwardly to overlie the handle at the sides of the kerf, spaced bridges connecting one end of the webs and defining between them a slot into which theblade may be entered, and means between the webs and remote from said end to cooperate with edges of the blade to position the same.

2. A fitting for mounting a blade in a kerfed handle comprising a pair of channels having closely spaced webs to be received in the kerf and their flanges directed outwardly to overlie the handle at the sides of the kerf, spaced bridges connecting one end of the webs and defining between them a slot into which the blade may be entered, and portions upstruck from the webs at a location remote from said end to cooperate with edges of the blade to position the same, said portions being in opposed pairs having a clearance between them in the normal unstressed position of the plates relative to said bridges.

LAURI C. BARLAND.
