BURGER, OF EAST CLEVELAND, OHIO, ASSIGNOR TO THE WARNER AND SWASF,Y COMPANY, OF CLEVELAWD, 01-IIO, A'- CORPORATION OF OHIO@ CROSS-SLIDE CARRIAGE FOR TURNING AND FACING. BLANKS. Application. filed April 7,1922. Serial No. 550,256. This invention relates to', an improved cross slide carriage for ttirnino, and f,@eing bevel gear and other blanks. The principal object of the present invention is to pro@ide a, turning and facing machine wherein the ore@test possible efficiencv is obtained in t:.urii7incr and facing bevel@ gear blanks and tlle lilce by the provision on a mdehine of the lathe t37pe. of v@n imptoved 10 cross slide carrielge havin& compouiided tool slides adapt6d to be provided with tools foi-'ti.irning and facing blanks 6f the type @ibove stttea together witli means for simultaneotisly opei-ating both slides so as to do i5 the work for which the machine is designed efficieiatly and a6curately, with the tools traveling in the correct,angular directions and @vith n-iinimum idle moirements. A further object is to obtain the above re-. 20 sillts with my invention embodied in the form of an attachment@ which cari be. applied. in a very effective manner to a standard mtchine such as a ttirret lithe or engine. lathe so ,s to transform the machine temporarily 25 int6 a i I ery 6fficient tilirning and facing macliine for turning and facing bevel gear blalnks and the like. A furthei- object of m@ invention is to I)rovide, iiieans whereby this' above stated 130 transformation, of -,t standard machine may be made in i, very simplified way by removing only a few parts of the standard machine and by . slid.ing the attachment into place with the iequirement o,lf but little time. 35 A Rirtlier object is tb attain the desired results -%vith a cross slide carriage having a plura-lity of tool slides which are moved in their in ividual paths which may be acljusted at will, from a unitary point or by a com40 mon memb,-r servinlcr to cause the slides to move simultaneously in the desired manIlp1r, wher(@by the results are obtained -w".th efficient but greatly simplified mechanism. A 'Lui-tber object i@ to carry otit the results 45 desirecl with an attachment which can be readily applied to a standard@ carriaoe of the lathe, and to provide certain mecha@ism for rrto-i,ing the sli.des, capable of b6ing ope,rated, by the niechanism of a standard 50 lctthe, eiiher from the usual cross slide operating m6chanism or @ from the usiial tiirret ol.)erating mechanism as may be desired.
