Description

H. A. BREMER ELECTRIC CONDENSER Filed Sept. 21
Patented Nov. 4, 1924.
' UNITED STATES HARRY A. BREMER, OF CHICAGO, ILLINOIS.
ELECTRIC CONDENSER.
Application filed September 21, 1923. Serial No. 864,002.
To all whom it may concern:
Be it known that I, HARRY A. BREMER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Electric Condensers, of which the following is a full, clear, 'concise, and exact description.
My invention relates to electric condensers employing plates arranged in groups or sides, the plates of one condenser side being interleaved with the plates of the complemental condenser side, one of the condenser sides having a supplemental condenser plate adjustable with respect thereto and with respect to the other condenser side.
My invention has for its general object the provision of improved means for effectv ing the mechanical and electrical assemblage of the supplemental condenser plate with the condenser side provided therewith. The invention also has for its object the provision of improved means for holding the supplemental condenser plate in the position to which it is adjusted.
In carrying out my invention I employ a spring member which performs the function of assembling the supplemental condenser plate with the condenser side provided therewith, this spring also serving as a brake to hold the supplemental condenser plate in adjustment. This spring is desirably in the form of a clip made of spring metal, the sides of the clip having the shaft that carries the supplemental condenser plate passing therethrough,
The invention will be more fully explained by reference to the accompanying drawing in which Fig. 1 is a longitudinal b section of a condenser as it is preferably constructed in accordance with my invention: Fig. 2 is a sectional view on line 2-2 of Fig. 1; and Fig. 3 is a perspective view illustrating the spring clip and a carrier therefore in separated relation.
Like parts are indicated by similar characters of reference throughout the different figures. v
The condenser shown includes a frame work composed of two boards or plates 1, 2, of insulation and their metallic posts 3, 4, 5, assembled with these boards to maintain them in suitably spaced apart relation. The condenser frame is mounted upon a panel board .6 in any suitable way.
The adjustable side of the condenser is' composed of semicircular plates 12 interleaved with the plates 7. Each plate 12 has a rim portion 13 in the form of an ear projecting therefrom, each rim portion 13 having a hole formed therethrough through which the post 15 is. passed. Washers 16 surround the post 15 and are interposed between adjacent plates to maintain them apart a suitable distance. The plates 7 have semi-circular recesses 7' that accommodate the post 15 and parts thereon. This post is mounted to turn to make the capacity of the condenser regulable. For this purpose there is a knob or handle 17 upon I the outer end of this post, and this knob carries a flange 18 which is provided with suitable scale divisions upon its periphery.
The supplemental condenser plate 19 has a shaft 20 which passes through the post or shaft 15 and is journaled therein. After the capacity of the condenser has been approximately adjusted, by turning knob 17,
final or fine adjustment is secured by turning the shaft 20, to alter the position of the.
supplemental plate 19, with the respect to th condenser sides. A spring clip 21 is placed upon a positioner 0r carrier 21' through which the posts 3, 4, 5, and the shaft 20 pass. The spring clip has its bight portion in engagement with the positioner 21', the ends of the spring clip being pressed against hub 22 of plate 19, and the nut 22' that serves to secure the plates 12, the washers 16, and the post in assemblage. The shaft passes through the holes 23 and 24 in the clip, the hole 24.- being larger to receive a portion of the shaft 15 also.
The spring clip is in firm engagement with the hub 22 and the nut 22' and serves firmly to press the hub portion 22 against a spring 25 that is employed to connect the condenser with one of its terminals 26. The
spring 25, which is in the form of a spring plate, is spaced at its free end from the board or plate 1 by a screw 26 so as to furnish a yielding contact against which the hub 22 is pressed by the clip 21.
Changes may be made without departing from the spirit of my invention, having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. A condenser including 2 condenser sides; one of which is adjustable with-respect to the other; a condenser plate element supplementing one of the condenser sides and mounted to turn with respect to both condenser sides; and a spring engaging the supplemental plate element and the condenser side supplied with this plate element.
2. A condenser including 2 condenser sides; one of which is adjustable with res spect to the other; a condenser plate element supplementing one of the condenser sides and mounted to turn with respect to both condenser sides; and a spring in the form of a clip, engaging the supplemental plate element and the condenser side supplied with this plate element.
3. A condenser including 2 condenser sides; one of which is adjustable with respect to the other; a condenser plate element supplementing one of the condenser sides and mounted to move with respect to both condenser sides; and a spring engaging the supplemental plate element and the condenser side supplied with this plate element.
4. A condenser including 2 condenser sides; one of which is adjustable with respect to the other; a condenser plate element supplementing one of the condenser sides and mounted to move with respect to both condenser sides; and a spring in the form of a clip, engaging the supplemental plate element and the condenser side supplied with this plate element.
5. A condenser including 2 condenser sides; one of which is adjustable with respect to the other; a condenser plate element sup plementing one of the condenser sides and mounted to turn with respect to both condenser sides; a spring engaging the supplemental late element and the condenser side supplie with this plate element; and a. spring terminal plate against which the supplemental plate element is thrust by spring.
6. A condenser including 2 condenser sides; one of which is adjustable with respect to the other; a condenser plate element supplementing one of the condenser sides and mounted to turn with respect to both condenser sides; a spring in the form of a clip, engaging the supplemental plate element and the condenser side supplied with this plate element; and a spring terminal plate against which the supplemental plate element is thrust by the spring.
7 A condenser including 2 condenser sides; one of which is adjustable with respect to the other; a condenser plate element supplementing one of the condenser sides and mounted to move with re ect to both condenser sides; a spring engagmg the supplemental plate element and the condenser side supplied with this plate element; and a spring terminal plate against which the supplemental plate element is thrust by the spring.
8. A condenser including 2 condenser sides; one of which is adjustable with respect to the other; a condenser plate element supplementing one of the condenser sides and mounted to move with respect to both condenser sides; a sprin in the form of a clip, engaging the supp emental plate element and the condenser side supplied with this plate element; and a spring terminal plate against which the supplemental plate element is thrust by the spring.
In witness whereof, I hereunto subscribe my name this 19th day of September, A. D. 1923.
