Specleation of Letters Patent.
Patented July 5,1921.
Application filed September 2, 1919. Serial No. 321,128.
To all 'ui/7mm t may concern.'
lle it known that l, lILLIAM L. Cn'rLiN, a citizen oi the. United States, residing at Chattanooga, in the county oi Hamilton and State of Tennessee, have invented certain new and useful linprovcments in Lathe- Tool Holders, of which the following is a` specification. l
This invention relates to improvements in duple.; tool holders, particularly designed i'or use with engine lathes for facing both sides oi' gear blanks, flanges, etc. rEhe invention is in the nature ot an attachment which can be used` tor turning periphery, and may also be used ona lathe which is provided with multiple stops, one tool being used for roughing and the other for tinishing.
lt is the common practice in many shops where automatic lathes are not used, to use a single tool lor facing each side or a flange or blank, this requiring in every case several settings of the tool, and frequent changes to secure the proper widths.
The object of the present invention is to provide an .improved tool holder which includes means for holding a plurality oit diiierent tools, one of which will act upon one part or" the work and another oi which will operate upon a different party oi the work.
Another object or" the invention is to provide a device of this character which may be adjusted to work upon standard dimensions,
so that other work may be operated upon and brought to the standard dimensions.
A further object is to furnish a duplex tool capable of operating upon work of various widths and which may be adjusted to accommodate dilierent classes of work.
With the foregoing objects outlined and with other objects in view, which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.
Referring to the drawing,
Figure 1 is a top plan view ot my improved duplex tool holder and showing the tools engaging a work piece.
Fig. 2 is a side view of the same.
Fig. 3 is a front end view.
Fig. 4 is a rear end view of a modification.
ln the drawing, 1 represents a tool slide on a lathe carriage and this slide is provided with a 'lf-shaped slot 2, which has its vertical portion opening upwardly. Resting on the upper tace ot the tool slide, is a base plate or tool holder 3 having a downwardly extending guide which rests in the vertical portion oi' the slot 2 and a bolt 5 has its head 6 located in the horizontal portion of the slot 2 and is provided with a nut 7. By loosening the nut 7 the plate 3 may be permitted to slide along the tool slide 1 and when the nut is tightened, it will iirnily lock the plate 3 and tool slide together.
The base plate 3 supports a plurality of levers 8 and 9 which ar pivoted or iulcrumed on bolts 10 carried by the base plate and provided with nuts 11. The bolts 10 pass through apertures 12 in the base plate 3 and a series of these apertures are provided for each bolt, so that the fulcrums ot the levers 8 and 9 may be adjusted toward or away from each other to permit the tools 13 and 14 to operate upon work pieces of various widths. The rear portions of the levers 8 and 9 are provided with arcshaped slots 15, through which pass bolts 16 carried by the base plate 3 and having nuts 17. These nuts are used for clamping the levers 8 and 9 in various positions and for holding the tools 13 and 14 in engagement with the work.
lt will be noted that the diameter of each bolt 16 is less than the width of each slot 15, to permit proper cooperation of the bolts and slots when the bolts 10 are 'shifted in the various apertures 12.
The extremities of the levers 8 and 9 are provided with n uts 18 and 19, one of which has a right hand thread and the other of which has a left hand tread and these nuts 18 and 19 engage the threads of a bolt 2O having threads on one side of one pitch and threads on the other side of opposite pitch. The bolt 20 constitutes an adjusting means for the tools 13 and 14 and it is provided with a milled hand piece 21 and a graduated dial 22, said dial cooperating with a pointer 23 carried by the base plate 8.
ln operation, the tools are set first for the roughing cut, and the operator notes the position oi the dial 22 relative to the pointer 231l and after the roughing out is taken, the hand piece 21 is turned to set the tools for the finishing cut, and the operator notes the position oi the dial for the proper position or" the tools during the linishing cut. On the subsequent pieces, it only necessary to 'that is mounted on the lever 8a.
turn the piece 2O to the positions determined on the irst piece operated upon. By this arrangement, the operator is enabled to iirst setthe tools to accommodate standard sizesV during the roughing and finishing cuts'and he can then obtain the identical cuts on subsequent pieces vby setting the dial 22 in the same position which it occupied .during the first cuts.V
lin the embodiment of theY invention'illustrated Vin Fig. 4:, the levers 8'LL and 9a are adjusted by means of a non-rotatable threaded bolt 202L which is carried by the lever 9i1 and coperates with a nut 21a, which is mounted between the varms of a lfork 2lb, The nut 21al has a portion of itsperiphery roughened, as shown at 22, to provide a hand piece and the remainder of its periphery fashioned to provide a dial 23, that coperates with a mark or point 24 provided upon one of the arms of the fork 2lb. It will be seen that by turning the hand piece 22a, the levers 82L and 9a may be moved toward or away from veach other and in this manner, tools supported by the levers may be adjusted toward or away from the v'work piece. Y
I am aware that various` changes and modifications may be made in the constructions illustrated and described without departing from the spirit of the invention as settorth in the following claims.
What I claim and desire to secure by Letters Patent iszl. A'lathe tool holder comprising abase plate, a plurality of levers having their inv termediate portions kpivotally mounted on said base plate, a tool carried at one end of each lever, a threaded member connecting the opposite ends of said levers, a single hand engaging member mounted' on-.the
threaded member for causing movement of the tools toward or away from each other, and a dial and pointer for indicating variousadjustinent's of said levers.
2. A' lathe tool holder comprising a base plate, a plurality of levers having their intermediate portions lpivotally mounted on.
said base plate, a tool carried Vat the front end of each lever, a nut carried by each lever, a movable member having oppositely -V pitched threads engaging said nuts, a hand' rengaging member liXed to said member `for causing movement of the tools toward and away from veach other, `and means for indi- Y member for causing movement of thetools toward or away from each other.
4. Alathe tool holder comprising a base plate, a plurality of levers havingtheir intermediate portions pivotally mounted'V onV said base plate, said levers being provided with arc-'shaped slots, threaded pins mountc edk on the base plate and` extending through said slots, nuts engaging said pins for lock-Y ing the levers in adjusted positions, tools carried bythe front ends ofsaid levers and adapted `to operate on opposite sidesof a work piece, nuts mounted onthe rearends of said leversa member having oppositely pitched threads engagingsaid last named nuts, a' handv engaging member and' a dial Y fixed to said threaded member7 and apointer cooperating with said dial for indicating various adjustments of said levers.
