To all whom it may concern: igspet end 5 are views showf lie it known that 1', WILLIAM Dosrninn, to make the sections of which the env citizen of the United States, residing at or easing of the condenser is constit New York, in the county of New York and these two sections being presented by State of New York, have invented certain 4: and 5 in the relative positions which new and useful Improvements in Electrical occupy when about to be 21Dll6l to the b Condensers, of which the following is e. of the condenser and secured in place, the specification. I two views being on s reeuced scale. This invention relates to an improvement The same numerals identity in electrical condensers such as are adapted parts throughout. for use in radio apparatus and other elec In the particular decor on of the trical devices. ferred form of my condenser her 1..

An object of my invention is toprovide a trated, use the number it to inoics condenser that can be manufactured in. 516: body or so-called stack Or the cone ventageous form and to the size required, which consists of a top and bottom i uiid so constructed that all liability of sheet of insulation, between which a t. breakage and derangement of structure or of conductive innteri such function is entirely obviated. and sheets of dielectric meteriei A; further object of the invention is to m ca, arranged in alternation so provide a condenser, the elements of which mica separates the foil; one-heir are arranged to be as compact as possible, Sheets of foil constituting one green o and which has an outer casing or envelope of plates for connection to one t that entirely encloses the body of the conan electric circuit, and the other r 3. denser, thereby greatly adding to the conductive sheets constituting co entree; strength and durability, and at the same taryset of elements forconnection. time permitting the condenser to beeasily posits terminal of the circuit. and conveniently connected in the circuit of ture and arrangement of the parts which it is intended to be a part. Preferstack 1 may be of any suitable ably, I make the enclosing easing of metal, and is not a part of the invention he but of course other suitable material may be f 'th. lhe body or stack 1, when so used. is covered by an envelopeor cnsin." r

in a, manner which will be more fully ex plained presenti At the o posits extremity, and flaming the recess are projections 10, adopied to be bent along transverse lines 11. At each side of -he blank or section 3 ere extensions 12, adopted to be bent along the two longitudinal lines 13 and one corner of these extremities 12" is rounded as shown at HR The projection 6 has a. perforation 15 in the outer ere trcmity of some,

The shape of the other blank or section is the some, and the various parts thereof are provided; with corresponding uumerels but the letter 10 is used in connection with each numeral so that this blank, and. its parts,- mey he distinguished throughout from the blank just clescrihecl.

To attach these two blanks to the stock 1 so cs make iihem hold together and, soclose stack, the stock can be first ie'd upon the blank as indicated by the.

The opposite ends of the condenser ssaclz: will ehouc coincide wi'ih. the lines 11 and che inner line 8*, and the top and bottom edges will. about coincide with the inner longitudinal lines 13*. The projections 10' the'lines 1) ouhword are at least as ioug es the thickness of the steak, auci these projections 10 are bent up against the adjacent end of the condenser at the opposite corners ihereoi.
