Specification of Letters Patent.
Patented Feb. 19, 1907.
Application filed March 21, 1906. Serial No, 307,185.
To all whom, it 'IIl/Ll/Z/ concern/.-
Be it known that we, GEORGE T. REIss, a citizen of the United States, residing at Hamilton, Butler county, Ohio, (post-office address care Niles Tool Works Company, Hamilton, Ohio and W ALTER L. CLARK, residing at New York, New York county, New York, (post-oflice address Trinity Building, New York, N. Y. have invented certain new and useful Improvements in T ool-Holders for Lathes, of which the following is a specification.
This invention, relating to tool-holders for lathes, will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a tool-holder embodying our invention; Fig. 2, a plan of the same; Fig. 3, a front elevation of the main structure, and Fig. 4 a side elevation of the heel of the clamp-lever in somewhat modified form.
In the drawings, 1 indicates the base portion of the tool-holder, to be formed with or secured to any ordinary suitable tool-rest; 2, the tool resting thereon; 3, ears, one at each side of the tool, rising from the front of the base portion, the distance between the ears being much in excess of the thickness of the tool; 4, a horizontal pivot carried by the ears above the tool; 5, a rearwardly-extending lever having its heel fulcrumed on the pivot; 6, an arch carried by the base portion rearward of the ears, the lever projecting in under the arch; 7, a vertical set-screw through the top of the arch, its foot impinging on the free end of the lever; 8, a swivel uniting the foot of the set-screw with the lever; 9, a block between the tool and lever; 10, a bearing portion on the under surface of the lever engaging over the block; 11, lugs carried by the base portion to the rear of the tool, one lug at each side; 12, horizontal set-screws threaded through the lugs and pointing forwardly; 13, a heelblock between the rear end of the tool and the forward ends of the horizontal set-screws 12; 14, a swivel uniting one end of the heel-block to one of the setscrews 12, whereby the screw may draw the block rearward and whereby the block may be turned upward out of the rearward paths of the tool; 15, horizontal set-screws carried by the base portion in position to engage the tool sidewise near its rear end, and 16 similar set-screwsto engage near the front end of the tool.
The power of the screw 7 in clamping the tool is greatly increased by the action of the lever, which, if the bearing portion 10 be nearly under the pivot, becomes a cam.
The bearing portion 10 of the lever is much broader than the tool, thus permitting the tool in being set to be shifted sidewise squarely or angularly without detracting from the clamping function. The block 9 is useful and in some cases preferable, but not essential.
The heelblock and the screws 12 prevent retreat of the tool, and the turning aside of the heel-block permits the tool to be withdrawn rearwardly. The set-screws l5 and 16 are not clamping screws and may if loosely fitted be adjusted by the fingers with out need of a wrench. They position the tool and meet its side strains ,thus restricting the screw 7 to the office of merely holding the tool down, as distinguished from also frictionally clamping the tool with sufficient power to prevent its horizontal shifting.
1. In a tool-holder for lathes,-the combination, substantially as set forth, of a base portion having a horizontal tool-supporting surface, downwardly acting tool clamping means carried thereby, and tool-positioning set-screws carried by the base portion at each side of the tool and between said tool-supporting surface and said tool-clamping means.
2. In a tool-holder for lathes, the combination, substantially as set forth, of a base portion having a tool-supporting surface, toololainping means OPPOSILG said surface, a movable heel-block carried by said base portion to the rear of said tool-clamping means, a pair of set-screws carried by said base portion and forwardly engaging the rear of said heel-block, and a swivel uniting one end of the heel-block to the forward end of one of said set-screws.
3. I11 a tool-holder for lathes, the combination, substantially as set forth, of a base portion having a tool-receiving surface, a pivot I carried by said base portion, a lever mounted on said pivot and having a bearing portion adapted toclamp a tool against said surface, and a power device carried by said base portion and engaging the free end of the lever.
4. Ina tool-holder for lathes, the combina tion, substantially as set forth, of a base portion having a tool-receiving surface, a pivot carried by said base portion, a leverrrnounted on said pivot and having a bearing portion adapted to clamp a tool against said surface, and a set-screw carried by said base portion and engaging the free end of said lever.
5. In a tool-holder for lathes, the combination, substantially as set forth, of'abase por tion having a tool-receiving surface, a. pivot carried by said'base portion, a lever mounted on said pivot and having avbearing portion adapted to clamp a tool against said surface, a set-screw carriedby said base portion and engaging the free end of. said. lever, and; a
swivel uniting the end of the set-screw with the-free end: ofithe lever.
6". In a tool holder for lathes, theoombination, substantially as set forth, of a base portion having" a toolsupporting surface, ears rising from the forward portion ofthe sides thereof, a pivot carried by the ears, azrear- Wardly-projecting lever mounted on the pivot and having a tool-cla1nping bearing portion,
1 arch carried by the base portion over the free end of the lever, and a setescrew carried by the arch and engaging the free end of'the lever. GEORGE T. REISS.
