ELECTRIC AL CONDENSER.
Specification of Letters Patent.
Patented Oct. 8, 190.7.
To all whom it may concern:
Be it known that 1', Lion GERARD, a subject of the King of Belgium, residing at Brussels, Belgium, have invented a certain new and useful Improvement in Electrical Condensers, of which the following is a description.
The object 1 have in view is to produce an electrical condenser which will permit of a close approximation of the condensing surfaces to obtain capacity, and will at the same time allow the use of currents of very high tension without endangering the permanency or elliciency of the apparatus.
In the drawing is illustrated in vertical section a construction designed to carry the invention into effect.
The inclosing tank 1 of metal is provided with an insulator 2 secured centrally upon its bottom plate, upon which insulator is supported a metallic cylinder. or rod 3 rising centrally in the inclosingltank and forming one of the condenser surfaces.
Surrounding the rod pr cylinder 3 and arranged con centrically therewith andwith eachother are placed a number of metal cylinders 4, 5, 6, 7, 8, which may be supported in any suitable way, such for instance as by screws 9 of insulating material which pass through screw-threaded holes in each one' of the cylinders into suitable depressions in the next inner cylinder, or in the case of the innermost cylinder into depressions in the central rod 3. These insulating screws 9 not only support the cylinders upon each other and upon the central red, but also furnish a means by which the cylinders canbe accurately centered upon each other and by which any tendency of the surfaces to change their relative positions will be prevented. The
The cylinders 4 to 8 may be made of cast metal with theirsurfaces machined so as to be truly concentric, and these surfaces are preferably highly polished, the cylinders being given a considerable thickness, which will not only permit this accurate machining of the surfaces, but will give the cylinders suflicient strength and stiffness to maintain their shape accurately. The cylinders are made of such progressively increasingdiameters as may be necessary to bring the surfaces into the close approximation required to give the desired capacity. The central rod 3 is also turned to a I true cylinder and its surfacepolished. The cylinders 4 to 8 are necessarily made progressively shorter from the innermost to the outermost cylinder in order to permit theproper configurationof their ends, but this can be done without material variation in the condensing surfaces since the shorter cylinders have a progressively greater diameter.
In order to permit the nesting of the cylinders upon each other, the upper flaring ends of the cylinders are made removable and are fitted to thebody of the cylinders by means of rabbet joints which hold the remov able end pieces concentric with the body of the cylinders. Thdcentral rod and the different cylinders are connected together electrically so as to form alternately different poles, which are j oined to the conduc- 7 tors 10, 11 leading through insulators 12, 13 supported in the cover of the tank 1. The tank is provided with a filling of a liquid insulator 14, such for example as a heavy paraffin oil preferably dried before use, which liquid insulator alsofills the spaces between the con- 30 (lensing surfaces and forms the dielectric between such surfaces. Owing to the heat produced at the condensingsurfaces and in the dielectric, a circulation of the liquid dielectric between the condensing surfaces is effected, so as to keep such surfaces The body of the liquid insulator in the tank is sufficiently great so that its temperature does not rise materially, ormeans may be provided for artificially cooling the liquid, as will be well understood.
This construction of condenser not only has the advantages before set forth, but is also one which can be cheaply manufactured by ordinary machine-shop opomtions. The number of condensing surfaces may be varied in accordance with the desired size and capacity of the apparatus, and for condensers of small capacity a single cylinder external to the central rod employed.
What I claim is:
1.. In an electrical condenser, the combination of vertlcally arranged annular condensing surfaces separated by annular spaces having a. gradually increasing width at the ends of such surfaces, an lnclosing tank, and a liquid dlelectrlcdn said tank filling the spaces between the con-, denslng surfaces and circulating therethrough, substanmay be tlally as set forth.
2. An electrical 'condensenhavlng condensing surfaces composed of several concentric open-ended annular plates, such plates from the one of smallest diameter to the one of largest dlameter having a. progressively increasing out '1 ward curvature towards their ends, substantially as set forth.
3. In an electrical condenser the*comblnatlon of concentric condensing surfaces having outwardly flared ends producing spaces of gradually increasing width towards the ends of the cylinders such cylinders being made progressively shorter as their diameters are increased, and a li uid dielectric filling the spaces between the cylinders,
substantially as set forth.
4. In an electrical condenser, the combinationofa series of concentric condensing surfaces having flaring ends producing spaces of gradually increasing Width at the ends L0 ut the cylinders, the ends of'the cylinders being removable to permit the assembling of the cylinders, and a liquid dielectric filling the spaces between the cylinde1's,-substantially as set forth.
