county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in GrindingQMacl-iines, of which the following is a. specifi- My said invention relates tien and arrangement of the driving gear for the carriage and the work'lholding mechanism ofa grinding machine,.whereby a'sing'le motor mounted` upon the machine itself, or any yother convenient power,l may be employed for driving said carriage and work without the use oftoverhea'd shafting, all as will be hereinafter more fully described and claimed. i

Referring to 'the accompanying drawings which are made a part hereof and on which similar reference eharacters indicate similar parts: Figure l is an elevation of one side of a grinding machine embodying my said invention, a portion of the head-stock base and frame being broken away to show the interior construction, and Fig. 2 a detail erosssection on the dotted line 2-.2 in Fig. l. i l

In said drawings the portions marked Arrepresent the main frame of the machine, B the traveling carriage, C the head-steek spindle, and Dthe motor for I The frame A and traveling carriage are of substani tially the same'form and construction asshown in 'several of my former'patents'. The grinding wheel W and the mechanism connected therewith are mounted on said carriage B and driven by a motor M also mounted on said carriage.` This feature of construction forms' .the subject' matter of a separate application and is 'therefore notparticularly described herein.`V 1

The head-stock spindle C is journaled in asleeve C1 which is swiveled-on the top of a base C2 whieh..is mounted to slide upon the top of the table C3.

The motor is an ordinaryelectric motor of suitable Ipower mounted upon a frame or bracket A2 secured rigidly to one end of the frame A of the machine.- It is connected by means of a belt l with a pulley on the end of a driving shaft 2 which is journaled insuitable bearings in the frame A? beneath said motor. -A gear 3 is mounted uponvsaid shaft 2 and meshes with Ya similar gear 4, mounted upon a drivingfshaft which is also journaled in bearings Vin frame A2 and is the shaft to which is geared the ,mechanism 'for driving the traveling carriage B. The gears 3 anda are preferably of that character which permits a change of speed be tween the parts, as shown. Another gear wheel 6 on 1 shaft 2 meshes with a gear 7 on the lower end of 'a vertical shaft 8, which shaft is mounted in suitable 'bearings in frame A2; Saidshaft 8 is provided with a joint Q eXtending in one direction and ajoint v extending inthe other direction, and between said joints it is to an improvedeonstruc? formed in two' parts adapted to telescope one within the other, being held from independent rotation'by being formed angular in cross section or by a spline and groove connection. Above the'joint l0 is mounted another gear wheel, II, which meshes with a similar gear wheel l2 on the end of a longitudinal shaft 13,

which is mounted at one end iu a bearing formed in a bracket A3 secured to the end of table C3 and at its other end is` mounted in bearings in the base (l2 of the head-stock, being adapted to 'slide through said bearings when said head-stoel; base is adjusted. A small gear wheel v14,I is mounted on said shaft l3 just inside of head-stock base and meshes with a gear l5 on the lower endA of a vertical shaft 1G, which is mounted in bearings in apart connected withthe'sleeve C1. Another gear wheel I7 on the same shaft meshes with the gear wheel I8 on a short horizontal shaft I9, mountedin the frame of sleeve@l and a gear wheel on the outer end of said shaft 19 engages with internal gear around the flange of the face plate C of the head-stock spindle C. By this arrangement lthe table4 C3 on which the head-stock' and the foot-stock C4 are mounted is permitted to swingen its pivot clamping bolt to any angle desired for the purpose of grinding tapered work or for any purpose, as will be readily understood. The table C3 is clampedito the bed by means of a pivot bolt l25 and washer 26, as indicated, and as shown in several of my former patents, for instance, No. 483,288.

The arrangement of gearing-for driving carriage B from shaft' 5 may be any arrangement -suitable for t the purpose, such as shown in some of my former pat- 1 ehtsbut I have indicated by dotted lines in Fig. 1.a j simple arrangement for the purpose of merely showing VAsonrieoperative connection. In the arrangement thus v shown, all worm is mounted upon-said shaft 5 adapted to mesh with a gear 3l on a transverse shaft 32 which has apinion 33 meshing with a4 raek-barB5 'on carriage B. The reversing clutch mechanism commonly used is -net shown herein. `This' 'arra ngementx for driving the carriageand the work by a,motor carried onthe machineitself is very simple and enables the machine to be driven without the use of overhead 'or line shafting while at the same time providing amachine adapted for universal grinding and to 4Aallow the various required speeds for the work and the several-adjustments of said work. 2 -v i I It is obvious lthat amotor need not be mounted upon the machineas: shown in drawing but power can be applied to thepulley on shaft 2 froniany convenient -source without departing from my invention, and' still avoid the use ofthe overhead shafting.

Having thu's fully described my said invention, whatv IV claim as new and desire to secure'by Letters-.Patent is1- A '1.
