ROUTER.

AApplication filed February This invention relates to an improvement in routers, and the like, vand has for an objecttol provide betterzmeans for mounting the motor constitutingvthe source of power, with respect to the element ofthe machine .receiving the drive from `the motor.

Another object consists in providing a universally adjustable y mounting for the motor. y

Another object consistsinprov'iding such a mounting which is conveniently supported from the machine proper so as to facilitate the drive.

Another object consists inprovidingy certain improvements in the form,.construc tion -and arrangement of the several parts .whereby'the above named and'othervobjects may effectively be obtained.

A practical embodiment is represented in the accompanyingdrawings, in which Fig. 1 represents a detailvplan'view of parts disclosing my invention;

In this class4 of machines,- the tool rotates veryrapi'dly.' and it. is Ia matter. of importance thatfthev drive :from` the source of power shall be; effective and vfree from abnormal conditionsor drawbacks.- An elec tric motor mayv be employed for the source of por/"Tier, and itis desirable that itspulley of the inventionV 1o, l1926. ser'iarNc. 8732i.v

"It is also desirable that the top of tlieniotor pulley shall be level withftheline of separation between the said rfast and loose pulleys.v invention includes means for nu'oiliitirrg.ther motor so that it can'attain and maintai-nthis position.

A second bracket v7 is 'fixed to and; projects from the bed 1 of Ithe machine, Iand has a substantially circular ertremity. `This vbracket is designed for the mounting ,ofthe electric motor 8. U j Y Said motor is bolted, 'jo'r otherwise 'suitably secured, to andiscf) *which is, itself, secured toa'plate QFby'meais ofcap screws 9** that fit in slots iformedin the plate 9* and are threaded into-fthe disc9.

This disc m"a'y be of any suitable forrn. .f j

The lp'latefQ* yis supported by vapliirality V(inV the present instance three). of cap screws V10 `that yare threaded through4 the circular extremity of the' bracket' 7 with their points extending upwardly. The cap screws thus constitute ja' three-'point support for the a central;apertureLlQgin:thejeitrenity 4off the bracket "I and itsvpoint isfthreadedf into the plate 9", wherebythesai'd cap screwserves -as means forfli'oldingr theplatefdown on the cap yscrews 10,.',b'ec'ause the fhea'd of the Vcap screw `,lll limitsv its y .upward move'm'entli'n the bracket. ,Y j. l' j As a resultof'the foregoing arrangement, it will` be Seen the 'height of the IIiiotor 8 with respect to the pulley's'l', Q ,Roan loevv regulated by adjusting the, screws ,110, lasavgr'oup,

zontal, planes, the belt makes a quarter turn, and this is a desirable drive for this machine.

y By reference to Fig. 1 it will be seen that the central plane of rotation ofthe pulley 13 is tangential to theperiphery of the pulleys 4,5, atfthe point where the belt 15 comes to seenY that the top of the pulley 13is level with the line of separation between the A'suaabie but Shifting device, including ya1s,t rap'16, a yoke 17, slide rod V1S, skeleton arm 19, and treadle rod 20, isV provided for causing the belt 15 to engage either .the fast or loose pulley, as desired.,V "Ihe specific form .l of this mechanism, which is well known,constitutes no part of this invention.

Referring to Fig. 4, it will be seen that the parts are the saine las described in connect-ion with Figs. 1 to Sinclusive, but there is av V'slight dilierence in application, in that the screws 10 are reversed sothat their heads stand up against the bottom of the plate 9*. This provides for an increased elevation of the said plate, and hence, of the motor it carries. `lIhe loperation of the partsis the i same als in connection with the disclosure of Figs. 1 to 3 inclusive.

Referring` to'theform shown in Fig. 5, the construction andV operation are the same as the form shown in Figs. 1 to 3 inclusive, except that the disc 9 and cap screws 9** are j 'omitted` The motor is bolted or otherwise suitably secured directly to the plate 9*, without any sliding adjustment thereupon.

It will be understood that various Vchanges may be resorted to in the form,`construction, andarrangement of the several parts'with` Y out ldeparting fromV the spirit and scope of my invention, and-hence I do not intend to Y be limited to the details herein shown and described eXcept'as they may be included in the claims.
