Specification of Letters Patent.
Patented J an. 8, 1918.
Application filed March 12, 1917. v Serial No. 154,157.
To all whom it may concern:
Be it known that I, PLA'roN LA ZAnroEs, residing at New York, in;the county and State of New York, have invented. certain new and useful Improvements in Tool-Holders, of which thefollowing'is a specificar tion'. i a
This invention relates to tool-holders, and
more particularly to a combination toolholder, such that the tool may be set .in different positions without disturbing the mounting or adjustment of the. holder proper, and whereby various kinds oftools maybe held in position to operateupon' the work. I
The prime object, of the present invention is to simplify the construction of tool-holders of this character as hitherto constructed, and to providean instrument which may be quickly andeasily adjusted to various positiOIlS. I .t I
A further object of the invention is to provide a new and improved instrument of the type which,-while possessing all. of the advantages of a single tool, may be utilized for the various purposes above indicated, and whereby one usingthe instrument may use the same to hold a tool to work either as a left, center or right tool ina lathe. I Other objects and aims of'the'invention, more or less specific than those referred to above, will be in'part obviousandinspart pointed out in the course of the following description of-the elements, combinations, arrangements of parts and applications of principles, constituting the inventionyand the scope of protectioncontemplated. will beindicated in the appended claims.
In the accompanying drawings, wherein I have illustrated a preferred embodiment of my invention, 7 I
Figure 1 is a view in elevation, partly in section, showing the same. H
Fig. 2 is a top plan view thereof; and Fig. 3 is a similar view of the turret head. Y Y
Referring now to the drawings, wherein similar reference characters refer to similar parts through the several views, the reference numeral 1 denotes the shank ofthe tool-holder, consisting of a straight rectangularly fo'rmedba'r, which is adapted to be mounted and clamped in the tool supporting device of a lathe in the manner in which an ordinary tool is usually supported. This shank portion at its outer end is provided with an enlarged portion or head 2, having a socket 3, the inner wall f thereof being formed from the arc ofa circle, and being inclined, ascle'arly shown in Figs. 2 and-3 of the drawings. The reference numeral '5 indicates a turret member, said turret member being of frusto-con cal shape, andl'is adapted to fit nicely within the socket 8, the upper wall 60f the member 5 engaging with the under surface of the arm? of the head 2, and the lateral wall of saidturret member engaging with the wall 4 of said head 2, as clearly shown in Figs. 1 and2 of the drawings. 1
Turret member 5 is provided with a centrally disposed threaded-aperture 8, which is located directly beneath an aperture 9 provided in the arm 7 of the head- 2, and extending through the aperture 9 and engaging the threads of the aperture 8is a clamp bolt 10, having a shoulder ll'adapted to rest upon the outer surface of the arm 7. By means of this" construction: it will be seen that when the turret member 5 is positioned in the head 2, the same may be firmly clamped against rotative, or in fact any movement therein, by means of this clamp bolt 10. Y ,The turret member 5 is provided with an aperture 12(which extends'entirely'therethrough, and is so formed as to engage the shank 13 of a tool inserted therein A threaded aperture 1% is located directly above the aperture 12 and leads into it,
:said aperture lt being adapted to receive a clamp screw 15, by means of which the tool 13 is held in position within the aperture12. The clamp or set screw 15"is 'pr'ovided with asouare'd or hexagonallv formed socket 16 adapted to receive a suitable-tool by means of which itmaybe manipulated.
shank or spindle of a boringtool, such as shown at 18, said boring toolbeing held clamped firmly in the Iabove set forth, in a construction :scope of the following claims, it
s-on-ly and notin a lim ting se in position in the aperture 17 as by meansof set screws 19 and 20 extending through threaded ape'rturesprovided in tlIQriUPPQI'IJS part of the turret member. The turret member is also provided with another horizontally formed aperture; indicated at- 21, this than the aperture 17,
aperture being smaller adapting it to receive the shank or spindle of. a smaller boring instrument, which may be clamped therein as means of the set screws 22 and 23. k I The manner of using my improved tool holder will be apparent to one skilled in the art without further description, served, however, that when the shank of the tool-holder has been properly supported and clamped in the lathe, .a tool of the type required to be used for any actor of work may be inserted within the aperture 12 and locked therein as by means of the set screw 15. T he set to the desired position by manipulating the clamp screw 10 to loosenv the turret member-5, whereby the latter may be rotated to such position as to carry the tool to the desired position relative to thework, whereupon said turret member vmay be then socket byvmeans of the clamping screw 10. Owing to. the fact that the turret member is .revoluble, it will be seen that tools may be set to, work on either the right or left, .or in.anvintermediateiposition. It willalso be seen that when it desired to usethe tool .for boring purposes that the required boring instrument can'be inserted in either of the apertures 17 or 21. o It will accordingly'be seen that I have provided an instrument. well adapted to attain, among others, allfthe aims and objects very simple and efficient manner. I 7 5 J As many changes could .be made in this without departing from the is intended that all matter-contained in the above description'cr shown in the accompanying drawing shall be interpreted as illustrative nse.
Having thus described my invention wh at I claim asneW and desire to secure by Letters Patent is:
