GUs'rAvE n. lnwonznreor siN-i?imNoisoo,catwomanv INSTRUM ENT-.MAKERs Toot- HOLDER To all w/Lom. it magj'conccru:
lle it known thatI I, Ges-ravi; 1I.. D\\"onz'EK, acitizen of thclfnited States, residing at San Francisco, in the county of San Francisco and state of `California, have invented certa-in new and useful Improvements in 'Instrument- Makers Tool-l lolders, of which the following is a specification. Y
)ly invention .relates to an improved instrument-lualers tool-holder for use with lathes, the object of my invention being to provide a device of this character by which the lathe-tools may be conveniently and successively presented in position in the order in which they are to be used upon an article turned ina lathe and so that. they can be readily applied one after the other without the necessity of nice adjustment by hand when a new tool is used.
)ly invention therefore resides in the novel construction, combination, and arrangementof parts for the above ends hereinafter fully specified, and particularly pointed out in the claims. c
ln the accompanying drawingsf Figure 1 is a perspective view of a portion of the lathe, showing my invention in use therewith. Fig. 2 is a top plan view of the tool-holder. Fig. 3 is a bottoni plan viewthereot'. Fig. 4t is a longitudinal section of the tool-holder. Fig. 5 is a longitudinal section on the li-ne A A of Fig. Fig. f3 shows the device held in a different manner. Fig. iisa detail longitudinal sect-ion through .the center of one of the enlarged cylindrical threaded portions of the slots to show the manner 0f holdingr the tool therein.
Referring to the drawings, 1 represents the stein of the t oel-holder, said stem bein gad aptcd to be held in the slide-rest 2 of the lathe 3 in the same way as the tool itself is ordinarily held. Said stem branche-S int-o forks 4, between theends of which isa bolt 5, which serves asa shaft forpthe rotating tool-holding cylinder 6. Said cylinder t5 is formed with a series of deep slots 7, extending therethrough parallel to the axis ot' the cylinder, said slots bein g enlarged at asuitable depth into .cylindrical and screw-threaded ways 8 to receive the screws 9. The tools are shown at 10 and rest in said slots between the ends of the screws 9, andare thus readily adjusted lengthwise Supposing that it is of the cylinder by .moving the screws 9 along the screw-thread ed ways S. it one end of the cylinder are secured the sect-ions l1 12 of an end plate, which sections have their opposite edges overhanging, so as to forni a beveled or undercut groove for the reception of a cutting-ott' tool-13. This tool 13 does not need to be adjusted except for wear, since it is used only for the purpose'of, cutting off the article after it has been turned. '.lo adjust for wear or grinding, the section 11 is removed and the tool moved up and s'aidsection then replaced. lt is therefore not necessary that the section 12 should be made removable, although so shown. cutting-ott tool is mounted a cylindrical stop 14, which is set at the proper point to determine the exact length of the article to be turned.
ln the slot-,T opposite to said lnthe'end of the cylinder opposite to-theA cutting-ott` tool are formed, one adjacent tolthe end of each slot, sockets l5 to receive the inwardly-extending end 1G of a locking-lever 17, actuated by a spring 1S.
The operation of il.' e device is as follows: d
esired to turn or fashion in succession a number of small articles identical in size and form, suoli articles bein-g cut oil? in succession from a rod orbar of the desired material, the first part of the operation consists in moving out'said rod until its end strikes the stop 14, it being observcd'that this stop vprojects farther outward than the cutting-ot tool, which is axiallyin line therewith. The rod being thus extended, the locking-lever is actuated to unlock the cylinder, and thepcylinder is turned by hand to bring the tool in the next slot into positio'nto operate Vupon the bar or rod. \\'hen the tool in t-his slot has been so operated, the cylinder is in like manner tu rned through another part of a: revolution to bring the next tool into operation. In certain eases, however, it is possible to make cuts with two tools in the same slot before thus turning the cylinder. The
operation is thus continued u util all the tools have been brought into cutting operation,
and finally the leutting-otitool 13 is used for' cutting ot the article which is heilig fashioned, the tool-holder being then in the position to commence upon anot her a rticle,where 'upon the previous operation is repeated.
The utility of this contrivance arises from the fact that in the ordinary manner of turning small articles, which depends upon adjusunent of the tool at a proper distance by hand, it is vimpossible to obtain articles accurately identical in size and form on aeeonnt of slight variations in adjustment of the cutting-toch \Vith this contrivance, after theseries of tools have been once set for cut-- already described, I provide the following. arrangement:- In the stem of the holder is-| formed an aperture 19,tlnougluvhieh is passed j a stud 20, extending upwardly frolna slide 2l,
heldin the undercut groove for the cutterholder, and upon the upper end of said stud is screwed a nut 22, thereby clamping the;
stein of the tool-holder in position, but permitting it to be set a greater distance from the axis of the lathe than when the stein is held in the ordinary cutter-holder.
I elaiinl. A tool-holder having asteln, a tool-holding body rotatably carried by said stem, and having a series of longitudinal slots for adjustably holding tools, said slots having enlarged cylindrical screwthreaded portions, screws in said enlarged portions for holding the tools, and lneansfor locking the tool- Aholding body at points in its rotation, snbstantially as described.
A tool-holder haring a stem, a tool-holding Jody reyolubly supported by said stem, means for holding a series of tools in said body at points around its circumference, an end plate removably secured upon one end of the cylinder and having an overhauging being also provided with a part having an overhanging edge opposite to the first over- 4S edge extending across said end, and said endhanging edge'to form an undercut groove for hol-ding a cuttingpt tool at the end of the tool-holding body, and means for loekingthe tool-holding 'body at points in its revolution,
'substantially as described.
In witness whereof vI have hereunto setmy hand in the presence of two subscribing witnesses. GUSTAYE ll. D\\'ORZEK. 'tnesseS:
