The wheel is convcnrently mounted by pressing the shaft, it against the panel by means of ntetai sprin r clips to which are fastened to the ancl and exert a sprint. action on the shaft. A groore across the clip serves to retain the shaft it in alignment. One of the clips is used as a l(lllllll;ll, as it makes electrical contact with the shaft and thus with the resistance. element 1. as previously explained.
The appearance of the completed rheostat is shown in Fig. 3. )fcourse, in cabinet. use the only part seen is a snntll portion of the wheel 6. The rest, howcver, easilt 1 accessible and the resistance rlmncnts may lie easily interchanged with very little labor or disturbance.
To recapitulate, this invention providcs a rheost-at which is made up of tt scniicirculor element 2 which may be clamped to a pant-1 3 so as to enclose a. portion of the regulatting wheel 4. By this construction a very compact and efiicient'f arrangement is secured which is admirably adapted for panel mountings.
The accompanying drawing, and related description, disclosing the nature of the invention, are not intended to be talien as the only embodiment nor to be construed so as to at all limit the spirit or scope of the invention.
I claim:
1. A rheostat comprising;- a mounting, an adjustment. control partiall projecting and a re- 3l illllt Qlttncht attached to said mounting as to part ially en ircle said vontroi.
2'. A rhcostat for panel iiiotiii'ti21g,'coinprisiug a scuiicircular resistor. a clamp adapted to secure said resistor to a panel pcrpendieular thereto, an adjusting wheel provided with a cont-actor cooperating with said resistor. and an axle electrically con ncctcd with said contactor, spring clips engaging said axle for mounting said wheel on a panel so that a portion of said wheel 1)lt) lt('t through said panel and the remainder lies substantially within the coinpass of said resistor.
:5. A rhcostai comprising a support having a slot thcrcin, an adjusting Wheel pet pendicular to said support and adapted to partially project through said. slot, retain ing incans to mount said adjusting wheel on said support, a semicircular resistor se-- cured to said panel so to encompass a portion of said wheel, a contactor mounted on said wheel in electrical connection with said rvtuinin; means and said resistor, and means for iiulicating the position of the contractor.
1. A rlicostat comprising a support, a rontrol lt'WtillilJl) mounted on said support with its axis parallel to the surface thereof, said control wheel partially projecting through an opening; in said support, a resistor mounted onsaid support, and a contactor enoug in; said resistor, said control being operable to client relative movement of said contactor and rcsist'or.
lu tcstiiiioii whereof I tjlliX my signature.
