SIGNORS TO THE LODGE & SHIPLEY MACHINE TOOL COMPANY, OF CINCINNATI, OHIO, A CORPORATION.
GAGE DEVICE FOR LATHES.
Specification of Letters Patent.
Patented Nov. 14, 1905.
To all whom it may concern:
Be it known that we, NICHOLAS D. OHARD and WILLIAM LODGE, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gage Devices for Lathes, of which the following is a specification.
Our invention relates to gage devices for the work-tool of an enginelathe.
One of the objects of the invention is to provide means for accurately setting or alining the tool relative to the tool-post, so that the tool may be fed into the work with precision at a predetermined point, the cutting edge of the tool being presented correctly.
Another object of the invention is to provide means for positively limiting the inward travel of the tool-post when it has reached a predetermined diameter relative to the work clamped between the spindles.
The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a top plan view of a lathe-bed, tail-stock, and carriage with our improve ment in position. Fig. 2 is an enlarged plan view of the'diameter-gage. Fig. 3 is a section on line 90 90, Fig. 2. Fig. 4 is an enlarged side elevation of tool-post, partly in section, upper portion of tail-stock with diametergage in position of centering. Fig. 5 is a side elevation of stop mechanism mounted on the tool compound rest. Fig. 6 is an enlarged front elevation of the stop shown in Fig. 5. Fig. 7 is a section on line w w, Fig. 5. Fig. 8 is a front elevation of one of the journalbrackets of the stop mechanism shown in section Fig. 7.
1 represents a longitudinal bedway. 2 represents the carriage thereon. 3 represents the tail-stock thereon.
4 represents the spindle or dead-center of the tail-stock.
5 represents the cross-rail of the carriage.
6 represents the base of an ordinary compound rest engaging the cross-rail 5, and 7 represents the tool-holder, having the base 7 which has a sliding gibway engagement with the upper face of the base 6.
8 represents the tool.
8 represents the hand-wheel for reciprocating the tool -holder 7 upon the base 6. (See Figs. 1 and 4:.)
The cross-feed-screw mechanism for reciprocating the base on the cross-rail 5 is not shown.
9 represents a collar adjustable rotatively upon the spindle of the tail-stock. It is provided with a radial alining-finger 10 and with a series of radial diameter-gage pins 11.
12 represents a stud secured to the base 6 under the projecting end of the tool 8. The stud 12 is provided with a center point 17. The finger 10 is provided with a center line 16. (See Figs. 1 and 3.) The finger 10 telescopes in the casing 13, projected from the collar 9, (see Fig. 3,) there being a spring 14 between the finger and casing holding the latter normally retracted. Finger 10 is provided with a handle 15, projecting through a slot in the casing 13, for manipulating the extensible finger 10.
On the side of the base 7 of the toolholder are brackets 19 19 (see Fig. 5,) in which are mounted an adjusting-screw 18, having the manipulating-knurl 2 1 20 represents a stop secured to the base 6 of the compound rest adapted to cooperate with the projecting end of the screw 18 to arrest the travel of the tool-holder upon the base of the compound rest at a predetermined point.
Bracket 19 is provided with the key 22, sliding within a groove formed longitudinally in the screw 18 to hold the screw against rotation, so that it may be longitudinally adjusted by manipulating the knurl 21.
ltlode 0f0peratt0n.'l he carriage is moved over toward the tail-stock and adjusted longitudinally of the bed until the line 16 of finger 10 registers exactly with the point 17 of stud 12, when the extensible finger 10 is brought into alining position. The collar 9 is then rotated and the finger 1O manipulated to bring the end of the finger opposite the tool' The tool is then adjusted in its seat until its cutting edge is alined with the line 16 of finger 10. As the line 16 also indicates the cen ter of the gage-pins 11, it is obvious that by this process the tool is not only alined substantially at right angles relative to the lathe axes, but that it is also alined relative to the gageins, so that the transverse position of the e ge of the tool can be properly gaged by these pins. Next, the pin of the desired gage of work is selected and by the rotation of collar 9 is presented opposite the cutting edge of the tool. The hand-wheel 8 is then manipulated to feed the tool-holder in until the edge of the tool just engages the selected gagepin. At this point the knurl 21 is rotated to bring the end of the screw 18 into engagement with the stop 20. The tool-holder can then be fed backward on the base 6, the car' riage moved opposite to its point of work, and the tool-holder fed in. Obviously the tool will then enter the work at the proper position, and the feed of the tool-holder will be automatically stop ed when the work has been reduced to the se ected diameter. It is obvious that this stop mechanism might be placed between a tool-holder and the crossrail of the carriage if a simple rest were used instead of a compound, it being the function of this rest to stop the traverse of the toolholder on the carriage at a predetermined point. v
Having described our invention, we claim 1. In an engine-lathe, the bed, carriage, tail-stock, spindle, and tool-holder trans versely slidable on the carriage, a rotatablyadjustable collar on the spindle provided with a plurality of different-lengthed gagepins, an adjustable .screw on the toolholder, and a cooperating stop adapted to be engaged by the end of the screw, to stop the traverse of the tool-holder at a selected point,
substantially as described.
2. In an enginelathe, the bed, carriage, tail-stock, spindle, and tool-holder transversely slidable on the carriage, a rotatablyadjustable collar on the spindle provided with an extensible alining-finger, an aliningstud on the tool-holder under the projecting edge of the tool, adapted to cooperate with the alining-finger for setting the edge of the tool, and means for clamping the tool on its holder, substantially as described.
3. In an engine-lathe, the bed, carriage, tail-stock, spindle, and tool-holder transversely slidable on the carriage, a rotatablyadjustable collar on. the spindle provided with a plurality of different-gaged pins, an adjustable screw on the tool-holder, a cooperating stop adapted to be engaged by the end of the screw to stop the traverse of the tool-holder at a selected point, an extensible alining-finger also projected from said collar, an alining-stud on the tool-holder under the projecting end of the tool, adapted to cooperate with the alining-finger for setting the edge of the tool relative to the holder, and also relative to the gage-pin, and means for clamping the tool in its holder, substantially as described.
In testimony whereof we have hereunto set our hands.
