ADJUSTABLE CUTTER HEAD AND' JEWEL BURNISEER.
@wwwa Patented Jan. 7, 1896.
NITED STATES PATENT OFFICE.,
LEMUEL N. JACKMAN, OF ELGIN, ASSIGNOR TO THE ELGIN NATIONAL IVATCII COMPANY, OF CHICAGO, IIrLINOIS.
\ ADJUSTABLE CUTT-ER-HEAD AND JEWEL-BURNISHER.
SPECIFICATION forming part of Letters Patent No. 552,687, dated January 7, 1896.
Application filed October 13,1893. Serial No. 488,068. (No model.)
To all whom it may concern:
Be it known that I, LEMUEL N. JACKMAN, of Elgin, in the county of Kane, and in the State of Illinois, have invented certain new and useful Improvements in Adjustable Cutter-Heads and ,Iewel-Burnishers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure l is a perspective View of my cutterhead arranged for use. Fig. 2 is a like view of the parts of the same separated from each other. Figs. 3 and 4 are respectively central longitudinal sections upon lin es .fr oc and z .e of Fig. l. Fig. 5 is a cross-section upon line y y of Figs. 3 and 4. Fig. 6 is a perspective view of my burnisher in position for use. Fig. 7 is a like view of the parts of the sameseparated from each other, and Fig. 8 is a central longitudinal section of the burnisher.
Letters of like name and kind refer to like parts in each of the figures.
The design of my invention is to facilitate the adjustment of cutting and other tools used in watch-makin g machines, and to enable jewels to be burnished into their settings with greater ease and accuracy; and to such end my said invention consists principally in the means employed for adjusting tools to and holding the same in position for use, substantially asand for the purpose hereinafter speci- It-consists further in the construction of the burnisher, substantially as and for the purpose hereinafter shown.
In the manufacture of watches and other line mechanism it is often quite difficult to set the cutters of lathes, and more especially those of automatic machines, and their adjustment requires much skill, patience, and time, and is usually effected by changing the form of each cutter until its operation is satisfactory.
To avoid such difficulty I employ a head A, which is adapted to be secured upon the end of a spindle B, or equivalent part, and within the outer end of the same form a dovetailgroove a similar to those employed in the slide-rests of' lathes. Within the groove a is fitted the correspondingly shaped end c of a block-C, which is adapted to slide lengthwise of such groove, and is moved to and locked in position therein by means of a screw I) that engages a threaded opening E in the head A, in rear of and in a line axially with said groove, and has a collar or flange d engaging a slot c in the contiguous face of said block.
In order that the engaging end or slide c may lit closely, but without undue friction, within the way a, the rear end of the block C is divided lengthwise from one edge nearly to the opposite edge, and through one of the parts thus formed` near' the cut edge is placed a screw F, which when turned inward bears against the inner face of the opposite parts` and operates to spread them, and thus widen one end of said slide. After the block C has been adjusted to position a slight inward movement of said screw will effectually lock it in place and prevent displacement. The outer end of said block is provided with an axial opening c2 for the reception of. any desired tool which when in position is locked therein by a setscrew c3 that passes radially inward, as shown.
This adjustable head is especiallyuseful in connection with a tool G for burnishing jewels into their bushings. As shown, said tool consists of a tube having a suitable diameter, with its outer end beveled in the form shown, and within its axial opening contains a rod I-I, which is adapted to rotate and slide freely therein. The rear portion of such rod is threaded, and carries a nut h that has substantially the same diameter as said tube, and may be adjusted toward or from its rear end.
The tool described, with rod or pump center inserted from the rear end, is placed within the opening c2 of the head C, with a spiral spring I around the portion of said center between the nut and its lower end, and is then locked in position by the set-screw c3. Said spring now holds said center with a yielding pressure at the outer limit of its motion, by which means when the tool is in use said center bears against the face of the jewel with sufficient force to hold the latter in correct position without in any manner interfering with the entire freedom of action of said burnisher.
`separated by the eut, into said groove, sub
stantially as and for the purpose speeified.
2. The combination of a block or support having a dove-tailed groove, a tool-Carrying head having an end shaped to it the groove, a screw engaging a threaded opening in the bleek and havinga eollar engaging a noteh in the head to adjust the head in the groove, and a serew engaging a eut or slit portion of the head to expand the same in the groove, substantially as and for the purpose shown.
3. The combination of a tubular burnishing tool, a spring pressed rod in the latter and a nut on the rod, to vary the pressure of the spring, substantially as and for the purpose deseribed.
In testimony that I elaiin the foregoing I have hereunto set my hand this 11th day of August, 1893.
L. N. JACKMAN.
