NEW BRITAIN, connncrrcor, A. conronarron or conro'on-smrnnme HOLDER.-

Patented Dec. 10, 1912.

Application filed July 18.1912. Serial No. 710,140.

To all 'whom it may concern Be it known that I, Josnrn M. HANGE,

: a citizen of the United States, residing at New .Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Tool-Sharpening Holders, of which the following 1s a full, clear, and exact description.

The present invention relates. to holders for cutting tools and specifically to one designed for use in connection with various forms of sharpening surfaces and affording means for adjustment to suit varying conditions as well as combining simplicity and strength of structure with a wide range of use. These and other advantages will appear from the more detailed descriptionfollowing taken in connection with the accompanying drawings forming part thereof and illustrating a preferable embodiment of the invention.

In these drawings, Figure 1 is a top plan view of the holder having a plane cutter mounted therein and in operatlve position on a flat sharpening surface. Fig. 2 is a side elevation, partly in section, of the parts shown in Fig. 1. vFig. 3 is an end elevation of the holder. supporting and guiding carriage. Fig. 4 is a transverse sectional view taken through the bracket carrying the tool planting screws.- Fig. 5 is a side elevation of the holder having a chisel mounted therein and in operative sharpening position on a grind stone.

Referring to the drawings by numerals: the main body of the holder is preferably formed as an integral structure, such as an iron casting, and embodies adownwardly inclined portion 1 of skeleton form serving as a tool seat and having an upstanding bracket 2 extending transversely thereover and spannin the tool seat, this bracket being provide with a plurality of threaded bores 3 therein extending longitudinally of the bracket and adapted toreceive clamping screws 4 whose lower ends, when screwed down, will engage a cutting tool, such as the plane cutter 5, and clamp the same on its seat 1. In the drawings I have shown three spaced threaded bores so that wide as well as narrow cutting tools may be clamped on the cutter seat of the holder. The spacing and number of these bores, however, may be varied within the practical accomplishment of the object recited. From the upper and therefor.

rear end of the inclined seat portion 1, the main body portion extends substantially horlzontally in .the.form of an integral arm 6. At its farther or rear end, forming the mar end of the body portion, this arm is formed with a I threaded bore 7.' The threaded standard 8 of a supporting carriage 9 engages with this bore and because of its threaded engagement therewith is enabled to rest'on a base and support the tool holder with the edge of the cutting tool car ried'thereby inclined at various angles relative to a sharpening surface with which it may cooperate. In order to securely lock the supporting carriage in its adjusted position relative to the arm 6, I preferably form one or more grooves'lO longitudinally of its threaded standard 8 :and provide the arm 6 at its farther end with a thumb screw 11 threaded into the extremity of the arm to extend transversely therethrough and into the bore 7 so that it may be moved to bring its inner end into engagement with a groove 10 to lock the standard Sagainst adjustment-destroying movement. The carriage 9 carries at its base a suitable roller 12 which forms an anti-friction bearing and support In Figs. 1 and 2 I have shown this roller resting on a base and the tool frame and tool cooperating with a flat sharpening surface, such as an oil stone 1.3. In such a construction, when the roller carriage has been adjusted to support the cutting edge at the proper angle to the oil stone surface, the tool holding frame may be freely moved back and forth, thereby moving the cutting edge of the tool back and forth over the stone and at the proper angle thereto; In Fig. 5 I have illustrated this same construction of holder applied to a grindstone 14 of the circular revolving type, the threaded standard 8 being adjusted to incline the cutting edge of a chisel 15, for instance, carried by the holder, at the proper angle for sharpening. The roller 12, of

course, rests on the edge of the grindstone ,and 1s revolved as the stone revolves.

From the foregoing it will be evident that I have provided a tool holder capable of a wide range of use in connection with various sizes of cutting tools, and provided with adjustable supporting means affording angular adjustment of the body and tool and affording a support for the tool holder ca pable of free rectilinearmotion to sharpen the same on a plane surface, and also adapted to properly osition and support the tool upon a curved rotating surface as well as adapted for use under various other conditions of'work.

I have described and illustrated a preferable embodiment of the invention, but desire it understood that the structure thereof is susceptible of modification withinthe spirit of the invention and the scope of the appended claims.

What I claim, therefore, and desire to secure by Letters Patent is:

1. In a device of the character described, in combination, an integral body having a tool seat thereon and provided with ,tool clamping means adjacent thereto, a support, for said body portion adjustable relative thereto, and meansfor locking said support in adjusted position. 7

2. In a device of the character described, in combination, an integral body having an inclined portion forming a tool seat and provided with tool clamping means adjacent thereto, and a support for said body portion adjustable relative th'ereto whereby the angle of inclination of a tool edge rela tive to a sharpening surface may bevaried.

3. In a device of the character described, in combination, an integral bod portion provided with a downwardly incllning tool seat at one end thereof, tool clamping means adjacent said seat, and a supporting carriage for said body portion 'connected thereto adjacent its opposite end.

4. In a device of thecharacter-described, in combination, an integral body provided with a downwardly extending tool seat at one end thereof and having a threaded bore formed therein adjacent its opposite end, tool clamping means adjacent said seat, and a supporting carriage havinga standard in adjustable threaded engagement with said bore and having an anti-friction supporting bearing at its base.

5. In a device of the character described, in combination, amain body portion having a downwardly inclining portion at its for ward end forming a tool seat provided with carriage provided with a supporting ro1er at its lower end and havlng an upwardly extending standard threaded to adjustably engage the threaded bore of said body portion, and means carried b said body portion for locking said standar in adjusted position.

6. In a device of the character described,

in combination, an integral body portion comprising an arm and a downwardly inclining portion extending therefrom to form a tool seat, and an independent support adjustably connected to said arm.

7. In a device of the character described, in combination, an integral body portion comprising an arm, a downwardly inclining portion ending therefrom and provided with a tool seat thereon and with a bracket overstanding and-spanning said tool seat, clamping means mounted in said bracket and adapted tobe adjusted to engage and clamp a cutting tool on said seat, a supporting carriage in adjust-able engagement with said arm and means for locking said carriage in adjusted position relative thereto.

8. In a device of the characterdescribed, in combination, a main body haying a downwardly inclining portion at its forward end forming a tool seat and provided with a bracket extending transversely of and overstanding said seat, a tool clamping member carried by said bracket and adapted to engage and clamp a tool on said seat, said body having a threaded bore formed therein adjacent its rear end, and a supporting carriage provided with a roller at its lower end and having an upwardl ard threaded to engage t e threaded bore of said body portion.
