MICHAEL FA'LOS, OF BOSTON, MASSACHUSETTS.

TOOL HANDLE.

Application filed January 18, 1923. Serial No. 613,385.

To all whom it may concern:

Be it known that I, MICHAEL FALOS, a citizen of Ukraine, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Tool Handles, of which the following is a specification.

This invention relates to new and useful improvements in tool handles of a type adapted to operatively support cutting tools.

An important object of the invention is to provide a tool handle, frame adapted for adjustment to accommodate tools of dif ferent lengths.

A further object of the invention is to construct a tool handle which embodies suitable construction to enable different types of tools to be supported thereby and to be used to the advantage and comfort of the person operating the same.

A further object of the invention is to provide a tool handle that is simple in construction, cheaply manufactured, strong, and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevational view of the tool handle embodying this invention and wherein the same is shown with a hack saw blade properly supported thereby,

Figure 2 is an end elevational view-of Fig. 1,

Figure 3 is a side elevational view showing parts of the frame broken away, and further showing one means of adapting the handle for supporting a file,

Figure 4 is a similar view to Fig. 3 and shows a second form of an attachment for properly supporting a file,

Figure-5 is a fragmentary sectional view taken on line VV of Fig. 1,

Figure 6 is a detail view of one of the clamping members employed by the invention,

Figure 7 is a detail view of one of the file supporting elements, and- Figure 8 is a sectional view taken upon line VIII-VIII of Fig. 1.

Referring to the accompanying drawing and particularly to Figspl and 2 there'is shown an adjustable tool handle frame embodying a rear section 1 and a front section The rear section 1 consists of a longitudinal channel arm 3 having formed integrally therewith and extending at right angles thereto, a depending leg 4 that is provided with a laterally extending foot member 5 at its lower end. This foot member 5 is longitudinally slotted for a portion of its length, as at 6, while the unchanneled portion 7 is provided with a longitudinally extending bore 8 which is adapted for loosely receiving the threaded end of a clamping element carried by the various tool engaging members. This rear section 1 is provided with a hand grip portion 9 that is similar in construction to the hand grip portion carried by the front section 2, but is somewhat differently formed in shape. As Fig. 2 shows an end view of the hand grip carried by the front section and better shows the exact construction, it is believed that a detailed description of this grip, when section 2 is more fully de scribed, will be suflicient for both.

The front section 2 is provided with a longitudinal arm 10 havlng a reduced end portion 11, as best shown in Fig. 1, and is further provided with a depending leg por tion 12 having an enlarged lower end 13. Formed in this enlarged portion 13, ad jacent its upper end, is a transverse bore 14 which is adapted for receiving one of the clamping members employed to support the forward tool engaging member and is further provided with a threaded recess 15 which is adapted for receiving the screw 16 therein. Referring particularly to Fig. 2 there is shown a forward hand grip which embodies a core member 17 that is formed integrally with the front section 2 and is provided with face plates 18 that are secured to the core by means of the screws 19 and are constructed from any suitable material, such as wood, bone. rubber composition, or the like.

Referring particularly to Fig. 1 and Fig. there is shown a means for securely clamping the two sections 1 and 2 in their adjusted position. The reduced end portion 11 formed on the longitudinal arm 10 is provided with a number of series of transverse recesses which, in this particular showing, displays two separate series, butit is to be understood that the number may vary according to the desire of the manufacturer without departing from the spirit oi? this invention. Each series GilllJOtllGS a central recess 19 and a pair of relatively small re cesses 20 that are positioned one on either side of the central recess. One side of the ('hannel arm 3 carried by the rear section l is provided with a similar series of recesses that are adapted to aline with the recesses 19 and 20 carried by the reduced end 11, while the opposite side of this channel arm 3 is provided with a single recess 21. that alines with the central recess formed in the first irnentioned side. The channel member 3 and reduced end 11. are adapted to be retained in their adjusted position by the clamping bolt that provided with a rectangular head adapted for carrying a pair of pin members 24 which are spaced laterally from the shank of the bolt. It will be clearly seen in "Fig. 5 that the bolt 22, when positioned within the recesses 19 and 21 and the recess alining therewith and formed in the opposite side of the channel arm 3, will properly position the pins 24: for being inserted through the suitable recesses formed in one side of the channel arm 3 and engage the similar recesses QOiiOrmed in the reduced end 11 and that the winged nut will retain these members in this assembled position when tightened upon the bolt 22.

The front tool supporting member is em-- ployed when the handle is used as eithera support fora hack saw blade or for a file and consists of a body portion 26 that is provided with a foot portion 27at its lower end, v Formedin' this body portion 26 is a longitudinally extending slot 28 that terminates short of the foot portion 27 and is adapted for receiving'the'bolt 16 which. is provided with a knurled nut 29, as shown. There further provided a clamping bolt 30 that extends through this longitudinal recess 28 and the transverse bore 14 formed in the enlarged end 13 of theidepending leg 12. This clamping bolt 30' is shown. in detail in Fig. 6 and embodies a rectangular head 31 that is provided with laterally extending lugs 32 which form pockets33 that are adapted for engaging the side members ofjthe body portion 26. This clamping bolt may be provided with a winged nut 34, as shown in Fig.1, or a knurled nut 35, as shown in Figs? and 4. The foot portion 27 carried by the body portion 26 is provided with a longitudinally extending bore 36 that is adapted to receive a hack saw blade supporting post 37 that is provided with a laterally extending pin 38 carried by the outer end andadapted to engage the usual aperture formed in the'end of a hack saw blade. The foot portion 27 provided with a transverse slot 39 that is adapted to receive a" pin 40 carried by the post 37 and is provided :tor allowing angular adjustment ofa hack saw carried by the frame? The rear support for the hack saw blade i1 comprises a body portion 42 that is adapt ed to be positioned within the longitudinally extending slot 6 formed in the foot portion 5, and is further provided with a longitudinally extending threaded post l3 that is positioned within the bore 8, as shown, and is adapted for receiving a knurled thumb nut 44- for securely clamping the supporting member in place. The body portion 42 is further provided with a depending leg .45 having a transverse bore lt that is adapted to receive the threaded post 47 which is provided with a laterally extending pin 18 for engaging the usual aperture formed in the end of a hack saw blade and is further provided with a winged'nut 49 which is employed to place tensionupon the hack saw blade a l for retaining it inits proper position.

Referring particularly to Figs. 3,4 and 7, thereis shown a clampingfmeans for securing various forms of files to the handle. This clamping element embodies a pair of side plates 50'and 51 which are adjustably engaged by the thumb screws 52 as best shown in Fig. 7. The clamping plate 50 is provided with a laterally extending arm 53 that is adapted to be positioned within the longitudinally extending slot 6 formed in the foot 5 and is furtherprovided with a threaded post 54 that is adapted to be positioned within the bore 8 carried by the said foot. This threaded post is provided with a knurled nut 55 which will securely'hold the clamping elementinplace. Theclainping plates 50 and 51 are provided upon their nnitingfaces with arecess 56 and lug 57 respectively which coacts with the thumb screws 52 for preventing relative movement between the two plates. Thereis also provided a substantially rectangular recess formed by mating channels 58and 59 which are adapted to suitably clamp the usual rectangulaifshank formed on certain types of files. Thereis further provided a sub stantially square recess 60 that is formed from channels cut in the mating faces of the two clamping plates and is adapted for securing a/square sleeve 61, as best shown in Fig, 4, which is provided with a longitudinally extending bore 62 adapted for re ceiving the shank 63 formed on the tile 6-4. This sleeve is further provided with thumb screws 65 for securely clamping the said file shank in place. i

It is believed from the above detailed description ofthe various elements assembled to provide this tool handle that no further explanation'is necessary. and that the operation will be apparent.

It is" to be understood that the form of this invention herewith shown and described is to be taken asthe preferred example of the same, and that'various changesin the shape, size, and arrangement of parts maybe resorted to without departing from the spirit of the invention or the scope of the sullijoined claim.

aving thus described the invention, I claim A tool handle comprising a pair of members adjustable longitudinally with respect to each other and means for securing said members in adjusted position, one of said members being provided with a vertical body portion terminating at its lower end in a rearwardly extending foot having a channel recess at its forward end and a wall at its rear end forming the rear end of the channel recess and provided with a bore, an an led tool support having a horizontal portion fitting said recess and provided with a threaded shank extending through said bore, a nut on said shank, said tool support further having a vertical portion provided with means for adjustably securing a tool thereto, the second member having a vertical body portion, a tool support mounted against the forward face of the lower end of the last mentioned vertical body portion and slotted from front to back, the slot extending from a point adja cent the upper end of the support to a point adjacent its lower end, a T-bolt extending through the upper end of the slot and the vertical body portion and having a nut thereon, a stud bolt screwed in said body portion and projecting through said slot, and a nut on said stud bolt.

In testimony whereof I aflix my signature.

MICHAEL FALOS.
