HARRY R. VAN DEVENTER, OF NEW YORK, N. Y.,' ASSlGrNOR TO DUBILIER CONDENSER CORPORATION, OF NEW YORK, N. Y., CORPORATION OF DELAWARE.

ELECTRICAL CONDENSER.

Application flled'March 11, 1925. Serial No. 14,814.

This invention relates to electrical condensers.

An object of this invention is the production of an exceedingly cheap and simple, yet effective electrical condenser;

Another object of this invention is the pro- I duction of. a condenser wherein the condenser sections are so arranged and maintained under pressure that the condenser will admit of heavy usage, the arrangement being such as to reduce to a minimum the matter of replacement and repairs.

A further object of this invention is the production of a condenser composed of but ,few parts substantially constructed, with a ready removal feature of any part which may to the particular construction, which for the pur Jose of explanation, have been made the sub ect of illustration.

In the drawings forming a part of this specification Figure 1 is an end elevation of a member with condenser sections mounted thereupon Fig. 2 is a sectional view taken on line 22 of Fig. 1; I

t Fig. 3 is a top plan view illustrating condenser sections mounted upon a bar;

- Fig. 4 is a vertical transverse sectional view of the form shown inFig. 3;

Fig. 5 is averticalsectional view illustrating a plurality of condenser sections mounted upon a circular member andv encased corre.-

sponding semi-globular housings; and

Fig. 6 is a transverse sectional view taken on line 66 of Fig, 5.

Referring by numerals to the drawings, 1 represents for example a copper'bar, mounted upon the opposite sides of which are corresponding condenser sections 2 clamped or compressed upon the bar by corresponding and oppositely disposed transverse'compres sion plates 3 having apertures 4 in their ends through which are passed corresponding bolts 5 provided with nuts 6. By screwing down the nuts 6, compression is exerted between the clamplngpart-s 3, thus compressing the condenser sections against the bar intermediate the condenser sections. Mounted upon the threaded end-of one of the bolts 5 over the nut 6 1s a nut 7 adapted to clamp between itself and the tap 6 a lead, not shown.

In Figures 3 and 4 I have shown a modified form, wherein the member 1 is of necessity wider, and is provided with an aperture 8 centrally'located as to its width. Arranged on both sides of the bar parallel to the edges thereof and adjacent to the aperture 8, are corresponding and oppositely disposed condenser sections 2. i

Bearing upon the condensersec-tion's 2 are -corresponding compression plates orclamps 9 having central apertures 10. .A'bolt 11 passes through the apertures 10 and the aperture 8 in the member 1. Mounted upon the protruding end of the bolt 11 is a nut 12,

I which, when turned down, exerts a compression between the clamping parts 9, and over the nut 12 is a nut 13 adapted to clamp be tween itself and'the nutv 12 a lead, not shown.

The aperture 8 in the member is 'much larger than the apertures 10 in the clamps and greater than the diameter of the bolt 11, hence member 1 does not contact with the bolt 11, however, the bolt 11 does contact with the clamps 9, and acts as a terminal.

In Figs. 5 and 6 I have shown another form wherein the member 1 takes the configuration of a circular plate havingfa terminal 14' formed upon its periphery. The plate has a central aperture 15 corresponding to the aperture 8, and a series of apertures 16 adjacent to its periphery, the object of whieh'will here inafter ap ear.

,Mounte upon eachside 'of the circular plat'e'l is'a series ofcondenser sections '2,

each oppositely disposed with relation to the corresponding section on the reverse side of the plate. Bearing against the condenser sectionsare circular compression plates v17 and 18. The'plate 18 is cut away, as at 1-9, in order to remove surplus material. The compression plates are centrally apertured, as at 20 and 21, the aperture 21 being threaded. A bolt 0r shaft 22 passes through the aperture 20 in the plate 17, the aperture condenser'sections2 upon the intermediate circular member 1. The bolt 22 has an elongation 23 which forms a terminal 24.

Mounted upon the reverse sides of the circular member 1 are corresponding semiglobular housings 25, each having a flange 26,

. the periphery ofwhich is equal to the peferred embodiment of my invention, I wish.

riphery of the circular plate 1. The flanges 26 are provided with apertures 27 which register with the apertures 16 in the disk 1, and bolts 28 are passed through the registering apertures for effectively securing-the housing in place.

One of the semi-globular housings 25 is provided with a central aperture 29, around which is formed a shoulder 30. An insulating sleeve 31 having a flange 32 is fitted into the aperture 29, the under surface of the flange 32 bearing against the shoulder 30. The terminal 24; passes through the sleeve 31 and is provided with a nut 33 which bears against the flange 32, and is further provided with anut 34 fitted on over the nut,33, and adapted to'clamp between itself and the nut 33 a lead, not shown.

If desired the member 1 in Figures 1 and 2 may be in the form of a plate, tube, split longitudinally and open at its ends, and filled with insulation 35.

While I have shown and described the preit to be understood that I do not confine my- 7 self to the precise details of construction herein set forth, by wayof illustration, as it is appjarent that many changes and variations may e made therein, by those skilled 1n the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims. I

Having thus described the various features of my invention, what I claim as new and desire to secure by Letters Patent is:

'1. In a condenser, a central member of conductive material, a condenser section on one face of said member, another condenser section on the same face of the member adjacent the first section, corresponding condenser sections on the opposite face of the member, clamping mem ers on the opposite sides of the central member engaging the condenser sections, and securing means for holding the clampin members in position to compress the con enser sections against the central member.

2. In a condenser, a central member of conductive-material, condenser sections on each of the op osite faces of said member, clamping members on the opposite sides of said member engaging said sections, and means for securing the clamping members in position to compress the condenser sections against the opposite faces of said member, said means passing through said central member.

3. In a condenser, a central member of con ductive material, a condenser section on one face of said member, another condenser section on the same face of the member adjacent the first section, corresponding condenser sections on the opposite face of the member,

5. In a condenser, a disk havin an aperture therein, a plurality of con enser sections mounted upon each side of the disk, clamping parts bearing against the respective condenser sections, a bolt passing through the clamping parts and the aperture in the disk, the bolt functioning as a terminal and exerting a binding force between said parts, and means for connecting a lead to the condenser.

7 In a condenser, a circular plate having' an aperture therein, a plurality of condenser sections mounted upon each of the opposite sides of the plate, circular-compression plates bearing against the condenser sections, a shaft passing through the center of the compression plates and said aperture, means upon the shaft for exerting a pressure between the plates, and a terminal formed upon the end of the shaft.

8. In a condenser, a circular plate having an aperture in its center, condenser sections mounted upon each side of the plate, compression plates bearing against the condenser sections, a shaft passing through the center of the compression plates, and said aperture, means carried by the shaft for exerting compression between the compression plates, and the end of the shaft forming a terminal. v

In a condenser, a circular plate, corresponding semi-globular housings oppositely disposed upon the plate, flanges upon the semi-globular housings, the peripheries of the flanges being equal to the periphery of the plate, a terminal formed upon the periphery of the plate, condenser sections mounted upon opposite sides of the plate, means for compressin the cond'ensersections upon the plate, one o the housings having a central aperture, and a terminal associated.
