To all, whom/ it pmj/ concern- Be it known thatI, rEoRGaI-E. S'ravnssa.
citizen of the United States, residing at Lynn,
'driving such tools.
county of Essex, State of Massachusetts, haveA invented 'certai nnew and useful Improvements in Drives for Machine-Tools, of which the tollowing-'is a specification.
j The present invention relates to machine-l chi ne-tools which may be readily actuated into and out of operative' relation therewith and the speed at which-the machine-tool is driven varied at the will of the operator without the use of current controllingy and regulating In the accompanying drawings', which ,form a part of this specification, I have shown one sensitive drill-press. Y
Figure lis a broken side elevation with the several parts in operative relation. Fig.- 2 is atop plan. Fig. 3 is-a broken frontelevation of the friction-disks and their-supports, drawn to a larger scaleand Fig. 4 is a front sectional 'elevation'of themotorv and its sup'- port, taken on line 4 4 of Fig. 1. v
A is the main column of the drill-press, provided with parallel guideways upon which a \ferticaily-adjustable bearing B for the drillshaft C is secured and has mounted thereon a platen I) and a fixed bracket E in which the upper part of :the drill-shaft C is journaled.-

The drive-- Patented set. v26. 1905.'
The means forchanging the position ofthe friction-disk 11 .relatively to the axis of rotation of the drill-shaft C. to thereby vary the speed of rotation of the latter,'consists of a yoke-piece 12, Surrounding' the hub of the disk at its inner end andflongitudinally movable at its outer end on a guide-rod 13, projecting tromthe motor-frame parallel to the shaft 9 and to the middle of which a latchlever 14 is pivoted. The latch-lever -14 is provided at its free end with a'handle 15 and at one side near its pivoted end with a' latch projection 16, which isfadapted to take into" a series ofvnotches 17 in the'guid-rod 13 The free end of the latch-lever 14-is carried 4in a guide-box 18, fixed to the forward end of the guide-rod 13, and is normally pressed toward the'rod 13'with its latch in engagement with-a notch 17. by means. of'a rollerY 19,located in the guide-box 18 and havingthe opposite'fends of its shaft 20 engaged by helicalsprings 21,l so lthat when -the` positionv of the disk 11,is to be changed the free`end of the llatch-lever 14 is moved against the tension of the springs21 untilfthe Ilatch projection 16 is removed from its notch, and'then by a `push ora pull upon the lever 14, according as it is desired nto decrease'or incrcasethe speed of 4`the drill, the friction -disk 11 is moved to aposition farther from o'r nearer `to the'axis of rotation of vthe drill-shaft and loekedin its adjusted position bythe engage- By pivoting the ,motor in a plane beyond available to press the friction drive members 11 and 4 into working engagement, and in rder tovary-the pressure exerted by the weight ofthe motor-upon the ,drive members a leaf-spring 22, adapted to exert a counterbalancing pressure upon the motor, israrrangedvbetween theunder sideof the motr "9e projection 16 with a corre- I OO and -the top of the `column A and connected to the latter by a serew`23.` The means fory disconnecting the driving member 11 from' the driven member to thereby ...'re'st'ifthe drill-shaft-/C without' stopping themotor consists of a l'ever.24, pivoted to'one 'side, of 'the bracket F in suchposition that its short arm may engage av shoulder orsurface of the motor and tilt the latter upward when the lever is actuated from the full-line position t thedotted positionin Fig. l.
IV do not desireto restrict myself vto`V` the particular form or construction of parts herein described and shown, since it is apparent that they may be changed and modified without departing from my invention. 4
What 1 clalm as new, anddesire to secure by LettersA Patent of the United States, is
1. The combination in a machine-tool, of a l vertical shaft, a friction-disk connected thereto, a.,pivotally-supported motor having its shaft arranged at an angle to the first shaft and provided with a friction-disk adapted to rest upon the side of the first friction-disk, and means for tilting said motor-'to engage and disengage said friction-disks.
pivoted upon a stationary part and adapted to engage said motor to tilt it. and disengage 'said friction-disks. t
3. In a machine-tool, the combination of a drive-shaft, a driven shaft, cooperating friction-disks connected to said shafts, and means for adjusting the position of one of said disks relativelyto the other comprising a yokepiece, a notched guide-rod and a springpressed latch connected to said yoke-piece and engaging the notches of said guide-rod.
4. In a machine-tooLthe combination of a drive-shaft, a driven shaft, coperating friction-disks connected to said shafts, and means for adjusting the position of one of said disksv relativbely ,to the other comprising a yokepiece in engagement at one end with the friction-disk, a notched guide-rod in engagement with the other` end of said yoke-piece and arranged parallel to the axis of said disk, a guide-block secured to said guide-rod, a latchlever pivotally connected to said yoke-piece and adapted to engage said notches and a spring carried by said guide-block and oper- -ating to force said lever into locked position.
