'ro'ALL WHOM 1r MAY CQ'NGERN: l A
Be it known that LfJUDSoN A.- CLEAVELAND, ot' vLa. Fayette, in' thelcouutyot Tippecanoe, and State of Indiana, have invented a new and useful Improvement in Tools for Turning Shafting and Cutting Screwsgandp.
I do hereby declare that the following is a fullIl (clear, and exact descriptionof thesame, reference being had to the annexed drawingsmaling part of this spe'eilcation.. Y
This invention relates to improvements upon George H. Wells's screw-cutting tool, patented April 2, 1867.' The improvement consists in the adaptation ofthe stock by changes in its construction, to use on ordinary. lathes, either for cutting screws or turning shutting, and secondlypin providing, for each of Athe cutters, sctf screws. which, acting independently, may be used for adjusting the cuttersseparately,while the whole are fedV simultaneously by a screw acting upon the rest. Y v
In the annexed drawings, A represent-s the ways of an'ordinary'lathe. B is thcstock for holding .the shaft to be cut; it is formed, as shown in the drawings, to slide on the ways, and having the front end turned upwardsv to support the jaw C, by which theA rod to be cut is securely clamped to prevent vibration of the rod or shaft whilesubjected to the action of the cutters. Dis the rest,l which supports'the cutters, and slides ou n dovetailed projection, D', from the upper face of the stock B. It is regulated -by-ia. screw, E, by which it may beY advanced or retracted, carrying'wjth it'the cutters. A round grbove is cutin the .top of the rest Dywhich catches the' foot of .theposts F. The cutting-tools, G, pass through slots in the posts, and are held firmly in g'against the cutters'.
0n releasing these set-screws the `cutters may be independently lregulated by the set-screws I, passing throng-lr lugs, I', attached to the rest D. The points of the setscrews I bear against thcreafr ends of the cutters.
By this arrangement the successive depth of eut of't'he various cutters in the series may be regulated es required, either to cut'the thread of a. screw or-to turn oil` thesurface ofshafting.
WhatI claim as my inveutiomnnd desire to secure by Letterslatcnt, is-
1.- Tho combination of the rest D, stock B, and jaw C, the cutters G, a.nd the setscrcws I, andlugs I, by which the cutters `nitty be independently regulated in relation to one another, While-the rest is adjustable, so as; to more all the cutters'siuiultaneously, substantially as described. l I r l 2. The stock B, when'vco'nstructed as described, in combination with the'rest, D, adjustingscrew Eend a. seriesllo' cutters, GG, substantially as and for the purpose set forth. n v
In 'testimony whereof, I have sign ed my ns'mcto this specicntionin the presence of two subscribing witnesses.
