Description

y 7, 1929. H. o. FARR'INGTON 1,711,931
MECHANISM FOR ADJUSTING CONDENSERS Filed Oct. 25, 1927 MMWMW //7 en tar V At t orneys 25 to those skilled in 5 the latter being mounted respectively on the shafts 0, c which carry the plates 12,11). As the shaft 9 is rotated in a' clockwise direction, the gear 0 will be turned,'then the gear 0.
10- It is obvious also that the principle of the ixivention can be applied to three or more plates or groups of plates as well as to the two illustrated in the drawing, since in such a case each cani'or gear may be divided into as many sectors as there are plates, one sector of each camhaving a spiral contour, the other sectors being circular.
do not confine myself to the use of cams such as are illustrated, but may employ other types of cams or levers or combinations of uivalent mechanical elements to obtain simi ar1 results.
Having thus described certain embodiments of this invention, it should be evident the art that various changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.
cams mounted shaft carrying said cams,
' lar contour,
I claim capacity, comprising fixed plates and a plu-' rality of movable plates,
a rotatable shaft, on said shaft, there being a cam for each movablepiafie, cam followers for said cams, and means operatively connecting said plates with their respective cam followers, said camsbeing shaped to cause said plates to move through their respective ranges of motion successively.
2. An electrostatic condenser,-comprising fixed plates and a pair of about an axis, a gear associatedwith each plate and mounted to move coaxially therewith, a rack meshing with each said gear, a cam engaging each said rack, a rotatable knob mounted on-an end of said shaft, one of said cams having a spiral contour over half its periphery followed bya semi-circuother said cams, having a semicircular contour followed by a spiral contour.
In testimony whereof I have afiixed my signature.
HERBERT o. FARRINGTON.
