TOOL-HANDLE.

Specification of Letters Patent.

Patented Dec. 7, 1909.

Application filed February 8, 1908. Serial No. 414,881.

To all whom it may concern.

Be it known that I, EDWARD KENER, Jr., a citizen of the United States, residing at Bufialo, in the county of Erie and State of New York, have invented a new anduseful Improvement in Tool-Handles, of which the following is a specification.

This invention relates to an ad ustable tool handle which may be readil attached to or removed from different kin s and s zes of tools, such as files, chisels and soldering none.

The object of this invention is to produce a handle of this character which is strong and durable in construction, which can be quickly and securely applied to differenttools and removed therefrom and which can be produced at comparatively low cost,

In the accompanying drawings consisting of two sheets :Figure1 is a longitudinal section of one form of tool handle embodying my invention. Figs. 2 and 3 are cross sections in the correspondingly numbered llnes in Fig. 1. Fig. 4 is a sectional perspective view of the partially formed clamplng sleeve or nut of my improved tool handle. Fig. 5 is a perspective view of theclampmg sleeve in its completed form. Flg. 6 is a perspective view of one of the jaws of the handle. Fig. 7 is a plan View of the partially formed body of the handle shown in Figs. 1, 2 and 3. Fig. 8 is a longltudinal section showing another form of tool handle embodying my invention. Fig. 9 is a front elevation thereof showing the tang of a tool therein in section. Fig. 10 is a cross section in line 10-10, Fig. 8. Fig. 11 is a perspective view of one of the jaws employed in the tool handle shown in Fig. 8.

Similar letters of reference indicate corresponding parts throughout the several views.

The form of tool handle shown in Figs. l7 is designed to be made wholly of metal. The body of this handle is constructed of a single sheet of metal so as to form two like arms or sections A, A which are connected at their rear ends by a transverse web a and each of which is semi-circular in cross section so that together they form a tubular or hollow body. The rear parts of these body sections are provided with perforations b so as to permit the air to circulate freely through the same and keep the handle cool, this being particularly desirable when the handle is applied to a tool which is heated as for instance a soldering iron. The sections of the body are free to move toward and from each other radially for adapting them to different sized tangs of tools, this movement of the body sections being permitted owing to the resilience of theweb connecting the rear ends of the same. During this radial movement of the body sections the same are guided upon each other but prevented from moving laterally with reference to each other by means of lipsv or ears 0 stamped out of the rear parts of the sect ons and bent inwardly from each body sectlon and against the inner side of the adacent portion of the other body section, as shown in Figs. 1 and 3.

The front end or shank of each body section has one half of a screw thread 01 formed thereon by stamping, the threads of both sections belng so arranged that they lead from one to the other and together form a screw shank on this end of the body.

In making the body of the handle a flat blank is stamped between suitably constructed dies so as to produce the semi-circular formation of the sections and form the threads thereon while the sections are unfolded and arranged end to end, as shown in Fig. 7 The sections are then folded toward each other along the central part of the connecting web a as a turning point and then the guide lips c are bent inwardly from each section and against the opposing section. Engaging with the exterior of the threads of the screw shank is a screw threaded clamping sleeve or nut which together with the shank embraced thereby tapers forwardly so that upon screwing the sleeve rearwardly on the shank the front ends of the body sections will be moved toward each other while upon screwing the sleeve forwardly the rear ends of the body sections are permitted to separate. This clamping sleeve or nut may be variously constructed but is preferably formed of a single piece of sheet metal which is first stamped from a blank so as to form two semi-circular threaded sections E, E arranged side by side, a longitudinal bead 6 connecting the adjacent longitudinal edges of the sleeve sections and dished in the same direction as said sections, a longitudinal.

sleeve sections are then bent toward each other on the connecting bead as a turning point and the channel on one section is interlocked or seamed over the flange on the other section so as to securely embrace the same, thereby completing the circular form of the sleeve, as shown in Fig. 2. This bead and seam form shoulders, projections or abutments which permit a firm grip of the hand tobe obtained on the sleeve and thus enable the sleeve tobe easily screwed on and off the handle body sections for tightening or loos ening the same on the tang of the'tool.

Wlthin the front ends of the body sections or arms are arranged two gripping jaws which are adapted to engage with opposite sides of the tang of the tool to which the handle is applied. Each of these jaws is preferably constructed of metal and comprises a semi-circular dished body G which tapers forwardly, a transverse web 9 arranged at the front narrow end of the jaw body and provided with a V-shaped notch or seat g and a transverse rear web it arranged at the rear or large end of the body and provided with a V-shaped notch or seat h in line with that of the front web. Each of these jaws rests within the concave side of the front tapering portion of one of the body arms and is secured therein both against radial and longitudinal displacement by means of retaining lips or lugs 2' formed on opposite edges of the respective body arm and bent inwardly against the concave side of the jaw next to the inner sides of both of its transverse webs, as shown in Figs. 1 and 2.

For the purpose of applying the handle to a tool the clamping sleeve is screwed forwardly 011 its arms to permit the front ends of the latter to separate the required extent. The tang of the tool is then inserted between the two-jaws and engaged on each side with the V-shaped seats of the respective jaw. Upon now screwing the sleeve backwardly upon the shanks of the body arms the same are drawn together and their aws are firmly pressed against opposite sides of the tool tang so that the handle and tool are firmly and reliably connected.

In the manufacture of this tool handle the use of solder is wholly eliminated, all the connections and fastenings being effected by bending lips or lugs so that the parts are interlocked or connected and held in place.

In the modified construction of my improved tool handle shown in Figs. 8 to 11, the body of the handle is constructed of a cylindrical piece of wood which is split lengthwise at its front end forming two arms A A which are connected at their rear ends by the unsplit rear part a of the body, while their front ends are constructed to form forwardly tapering shanks, The opposing inner sides of these arms are proits outer part forms one half of an external screw m. The seats of both jaws are arranged opposite each other and are adapted to engage with opposite edges or sides of the tang of the tool against which they are firmly held by means of a screw sleeve E engaging with the threaded outer parts of the ferrules in the manner described with reference to the construction shown in Figs. 17.

Each of the ferrules is preferably constructed of sheet metal and held in place on its body arm by means of spurs a arranged at the rear end thereof and driven inwardly into the respective arm, as shown in Fig. 8.

My improved adjustable tool handle is not only convenient in use but also effects a considerable saving in expense inasmuch as it is more durable than the ordinary handle heretofore in use.
