Specification or Letters Patent.
Patented Apr. 20, 1920.
Application filed November 4, 1919. Serial No. 835,774.
To all whom it may comem:
Be it known that I, ROBERT J. Frrza citizen of the United States, and
GERALD residerit of New York city borough of Manhattan, in the county oi New York and State of New York, have invented certain new and useful Improvements in Condensers, of which the following is a specification.
This invention is an improvement in condenser and has for its main object to provide more efficient and more easily applied insulation for the condenser plates. My invention is not limited to any particular form of condenser but possesses special ad vantages in connection with a condenser of that type in which there are relatively movable plates whereby the capacity may be varied.
As an important feature of my invention I coat the various conducting elements with a non-conducting film permanently deposited thereon and enveloping the conductor. This non-conductin film, coating or jacket is preferably of sue a character that it is not affected by the temperature, chemical or electric condition to which the condenser is subjected. As an example of such a film or coating I may employ an enamel 80 composition of such a character that it may be baked on to the plates or other conductors.
In the accompanying drawings I have illustrated merely one embodiment of my invention and have illustrated this on a very greatly enlarged scale, so far as the thickness of certain of the parts is concerned, in order to facilitate clear illustration.
In these drawings: Figure 1 is an inverted plan yrew; Fig. 2 is a section on the line 2-2 of Fig. 1
ig. 3 is an enlarged view of one of the 1 elements.
In the form shown, the condenser is mounted on a slab 10 of any suitable nonconducting material. A plurality of sta tionary condenser elements or plates 11 of substantially semi-circular form are rigidly secured to said slab by connecting bolts 12 or other suitable means and the plates are held in spaced IQlfltiOnBhlK by spacing plugs, collars or strips 18.
second series of substantially semicircular plates 14 are connected to a shaft or rod 15 and held in proper s aced relationship b spacers 16. The sing e rod 15 is mounted in the slab 10 to serve as a pivot and support for the plates. The rod 15 extends through the plates 14 approximately at the center of the curvature and is positioned substantially at the center of the curvature of the stationary plates 11. The latter are shown as cut away midway of the straight side to form a recess 17 receiving the rod 15 and the spacers.
As previously indicated the plates are shown greatly magnified, particularly so far as thickness is concerned. The plates 11 and 14 may be made only approximately one hundredth (.01) of an inch in thickness and the spacers are only of such thickness as to permit the movable plates to freely pass between the stationary ones. With the parts in the position shown in the drawing, the maximum surface of each plate is opposite to that of another plate, whereas by rotating the rod 15 by means of a knob or handle 18, or other suitable means, through 180 degrees the movable plates may be entirely moved from between the stationary ones. As an important feature of my invention each plate has a non-conducting coating 19 thereon, the coating being of the proper thickness in accordance with the electrical pressure to which the condenser is to be subjected. This coating may be of an enamel comcposition baked on or permanentlydeposite thereon but, in any event, should-be of such material that it will not be affected by and will adequately withstand temperature chemical or electrical conditions to which the condenser may be subjected.
By means of my invention the use of separate insulation plates is avoided, each plate carries its own insulation and in case of the breakage of the insulation of any plate the plate may be readily removed and replaced by a new one. As previously indicated, I do not wish to be limited, to the particular form of condenser illustrated as my invention may be applied to various diflerent types. I do not desire to be limited to the small number of plates shown, as in practice a very large number may be used.
Having thus described my invention what I claim as new, and desire to secure by Letters Patent is:
An electric condenser includin a plurality of, stationary conducting ates and a plurality of interposed mova 1e plates connected together and movable in their own planes into and out of position between said stationary plates, each plate having a non-conduotin film or coatin on both sides t ereof to inclose t e plate, the coating of each movable plate being spaced from the coating of the adjacent stationary plate by thin air spaces.
SIiIgned at New York city, in the county 16 of ew York and State of New York, this 28th day of October, A. D. 1919.
