Description
IVLPETERS, PHOTO-LTHUGHAPHEH WASHINGTON D C `TO ALL WHOM IT MAY CONOERN;
@uitrit .gratte gamut- @frn Letters Patent No. 78,387, dated May 26,- 1868.
IMPBOVED HOLDER FOR LATHE-PLANERS.
dlgs Signale nimh tu ir; there tettnr rttnt mit lurking part nf tirarme.
Be it known that I, JOSEPH P. MANTON, of the Vcity and county ofProvidcnce, in the State of Rhode Island, have invented a new and useful Improvement in-Tools for Lathes, Pl'aners, and similar machines; and I do hereby declare that the following specification, taken in connection with theA drawings, making a part of the same, is a. full, clear, and exact description thereof..
Figure 1 is a top view of the holder and its too-l.
Figure 2 is a side' View.
Figure 3 exhibits a side view of one of. the halves of the holder, and also-a top view ci" the same.
Figure 4 is an end view.
Figures 5 and 6 are parts to'be referred to.
Figure 7 exhibits'th'e cutting-tool.
It is advantageous to machinists employing lathes,1 planets, and like machines, to make'usc of toolfholders of iron, in which the cutting-tool can be secured, instead of forging, from steel,'the tool and shank in one piece.- The economy in time and material which results from the employment of independent tools and holders is well understood.
Various tool-holders have been heretofore devised, but all with which I am acquainted are objectionable,
Aeither on the score of inability tohold the tool firmly, so as to prev-entits chattering or, if unobjeetionable on this account, are costly in structure.
In the drawings, fig. 1, it will be seen that my improved tool-holder A consists of tivolbars, a d, of metal, placed side by side, the two so placed together being of the convenient dimensions to suit a. tool-post. Near their rear ends, these two bars :ire held together by a rivet, b, or are otherwise firmly united, but a portion of their surfaces, in juxtaposition, say from their front extremities tothe point c, is cut away. The purpose of so cutting away their surfaces is to enable that end of the holder to yieldto the strain of a clamp-nut, B.
Thetool G is set, at any convenient or preferred angle ,with the axis ofthe holder, in a mortise, D, onehalf of such mortise being made in each of the bars making up the holder. The size and form of the mortise should correspond with the sizerand shape of the tool, but should be always such that, when the two parts a a of the holder are strained toward each other, at. their forward end, by the clamp-nut B, tho tool will be firmly griped.
tool-holder made as described can be manufactured at a. comparatively trilingexpense, as compared with others, for the same purpose, heretofore known, and, in point of strength and capacity to hold the tool firmly, is superior to any other. i
What I claim as my-invention, and'desire to secure by Letters Patent, is
A tool-holder, constructed substantially as herein described.
l JOS. P. MANTON.
