Application iled November 1,0,.K1911. Serial No. 659,475.,
Zh all whom z't may concern.'
' Be it known thatL HERMANN NEWMANN, a' citizen 'of Germany, residing at New 'York city, county and State of New York,- have invented a -new and Improved Turret Attachment for Engine-Lathes, of which the follow-ing -isa specification.
This invention relates t0 a novel turret for lathes which is adapted to be secured more particularly to the slide restof an engine lathe.
The turretcomprises essentially a rotatable holder that supports a plurality of tools extending alternately in a radial and axial direction.
The invention further' comprises novel means for locking said holder against rotation, after a selected tool has been brought into working-position. y
In the accompanying drawing: Figure 1 is a face view of av turretattachment embodying my invention; Fig. 2 a vertical section on line 2-`- 2, Fig.- 1 showing some of the parts in view;- Fig.- 3 a top view ofFig.y 1; Fig. 4 a cross section on line L1:-4, Fig. 2, and lFig. 5 arear view of Fig. 1.
M-y turret 'attachment is shown to be secured to the to-p slide of a cross-feed slide rest 11, although it is obvious that it may also be supported by a compound slide rest without depart-ing from the spirit of my invention. Slide 10 is provided with a rela'-l tively iixed- Z-shaped support 12, the upper horizontal'arm ofwhich 1s rovided with a groove 13. Into the latter is fitted the depending feather 14 of an L-shaped bracket 15, the parts 1 2 and 15 being held in position by passage of a screwbolt 18, the head 19 of recess of va "circular-tool holder 20, whereby a screw=21 tapped into said head andholder prevents an independent rotation of these parts. 'Diskl 20` is preferably slightly vided with a plurality of spaced bosses 22 preforated as `at 23, six of said bosses being shown in the drawing.l Perforations 23 extend'in parallelism with the axis of bolt 18 and are adapted for the'reception'of suit-` able tools (not sh'own), which may be held in position by clamp screws 24. Intermediate bosses 22, thereis arranged u A 20,1 apliiralityof radially'disp'ose Till-shaped a screw bolt 16 having countersunk4 nut 171. Bracket is perforated for the.
on holder.
screws 26, which are tapped into the clasps and pass loosely through elongated bores or slot-s 27 of the holder, to permit a slight adjustment of the tools. Owing tothe slight concavity of disk 20, clasps assume a slight dip, so as to throw the Workingedges of the tools well forward of the tool holder and' thus obtain a desirable clearance between the .work and the holder.
intermediate bracket 15 and holder 20, Lthere is fitted upon bolt 18 a disk28 which is connected to theholder by pins* 2.9 so as to participate in the rotation thereof. Disk 28 is provided with peripheral notches 30, the number of which corresponds to the combined number of bosses 22 and clasps 25. Notches 30 are adapted to be engaged by a deten't 31 pivoted to bracket 15 at 32 and .influenced by a spring 33. The threaded section of bolt 18`is engaged by a clamping nut 34 adapted to frictionally engage bracket. 15 and having a neck 35 which is loosely encircled by a ring 36. The latter has a pair of lugs 37 straddling an elbow lever 38 that is fulcrulned to said lugs vat 39. The upper arm ofleverI 38 constitutes a handle, While the lowerarm is adapted to be received Within either one of a plurality of transverse grooves 40 formed on the periphery of nut 34. The rearwardly protruding fend ofy -bolt 18'carries a. radial pin 411 which is adapted to engage a pin 42 of nut 34 that extends in parallelism with the axis 'of bolt 18.
f In lise, the bosses -22 and clasps 25 hold ,a plurality of different tools adapted to perjforml the various operations in metal Yetc, working, the particular tool in use being 'always horizontally alined Wit-h bolt 18. If it is desired to bring another tool carried by holder 20 into the operative iwi-1mm Y handle of lever 38 is rotated while the lower arm of the latter inserted into one of the grooves 40, so as to loosen nut 34, and thereby render holder 20 turnable. Lever 38 is then thrown up to release nut 34and the AAea Y latter is turned by hand to impart a correaxis ofthe holder being ascertained-by the cooperation of the notched disk 28 and de-g tent"'31.` Nut 34 is now tightened up bye to said y'holder by "hand, and lever 38 is tilted until its` lower arm engages one of the grooves-l0, wherebyy the handle of said lever is utilized for linally tightening nut 34, in which position the parts remain until a furtheryexchange of tools is necessary when the operation described is repeated.
I claim:
1. A turret for lathes comprising a bracket adapted to be secured to a sliderest, a bolt rotatably mounted in said bracket, a tool-holder non-rotatably secured to one end of the bolt, a grooved clamping nut carried by the other end of the bolt and adapted to frictionally engage the bracket, a ring encompassing the nut, andV al lever pivoted to sai/d ring and adapted to engage the nut-grooves.
2. A turret for lathes comprising a bracket adapted to be secured to a slide rest, a screw bolt rotatably mounted in said bracket, a tool holder carried by said bolt, a grooved nut engaging the bolt, a ring turnable on said nut, anda tightening lever pivoted to said ring and adapted to engage the nut-grooves.
3. A turret for lathes comprising a bracket adapted to be secured to a slide rest, a headed screw bolt rotatably mounted in said bracket, a tool holder non-rotatably secured to the headed end of the bolt, a radial pin carried by said bolt, a clamping nut engaging the boltand having a pin that is adapted to be engaged by the first named pin, and means for tightening said nut.
