CONDENSER.

appntion mea my 5,

To all whom# concern:

Be it known that I, PETER G. JAcoBsoN, citizen of the United States, 'residing at and State of'Illinois, have invented a certain new and useful Improvement in Condensers, of which the following. is a full, clear, concise, and

exact description.

My invention relates to electrical condensers and has for its object the provision of improved means for effecting the assemblyo-f the leaves which comprise the sides thereof.

In accordance with one characteristic of the invention there' is a mounting sleeve having a plurality of sets of arcuate slots distributed along the sleeve, the leaves of one condenser side entering said slots and being recessed to receive the unslotted portion of the sleeve which is formed with interleaving fingers that margin the slots therein. These fingers are preferably of wedge formartion whereby they exert'pressure upon each other longitudinally of the sleeve upon con' traction of the fingers. The spaces between the fingers extend through the material of the sleeve or tube into communication with the bore of the sleeve or tube.

In accordance with another characteristic of the invention the leaves of the other condenser side vare rovided with a mounting rod and a longitudinally split sleeve embracing said rod and formed with transverse fingers between which portions of these leaves are re` ceived whereby they are assembled with said Y rod. The leaves are desirably provided with aligned recesses through which the mounting rod is passed, there being fingers upon opposite sides of the split in the sleeve so that portions of the leaves which margin both sides of the recesses therein may be received between the fingers upon the sleeves.

There are preferably three such rods associated as described.

I will explain my invention more fully by referencev to the accompanying drawing in which Fig. 1l is a view in elevation, partially in section, of a condenser constructed in accordance with the preferred embodimentof the invention; F1g. 2 is a sectional view on line 2--2 of Fig. l 1; Fig. 3 illustrates some of the condenser leaves of one .condenser side and parts for assembling the same; Fig. 4 1s a view showing the sleeve offngered formation and some of the condenser leaves assembled therewith; Fig. 5

illustrates some of the condenser leaves of the other condenser side and the fingered sleeve for assembling the same, one condenser leaf being shown in assembly with the sleeve and another in and Fig. 6 is an enlargement of a portion of n 1g. 2 but before the split sleeve shown in this figure has been clinched into engagement with the rod passing therethrough, the clincning of the sleeve being indicated by dotted lines.

Like parts are indicated by similar characters of reference throughout the different figures.

The condenser illustrated includes two mounting plates l and 2 of insulating material which are assembled upon threaded metallic rods3 by means of nuts 4, 5, 6 and 7. These rods are assembled with the mounting board 8, there being distance preserving sleeves 9 that intervene between the nuts 4 andthe insulating plate 1. One of the con- 'denser sides is composed of a group of metallic leaves 10 yformed with aligned U- shaped recesses 11 through which the mounting. rods 3 pass, there being preferably three such mounting rods. A longitudinally split metallic sleeve or tube v12 embraces each rod 3 and is' formed with transverse fingers 13 upon opposite sides ofthe split in the sleeve, these fingers entering the spaces between the leaves. The spaces or slots 14 between the fingers communicate with the interiors or bores of the sleeves andvsnugl receive the portions of the leaves which7 margin the sides of the recesses 11 therein. In the process of assembly the split sleeve 12 is preferably initially of U-form as indicated in Figs. 3 and 6, the ends of the fingers being-clinchedinto engagement with the corresponding rod after the sleeve has been placed upon the corresponding rod with the sides of the recessll in the slots Abetween the fingers thereof.

The other condenser side'com rises leaves 15 which are interleaved with ti e leaves 10 and a metallic mountin sleeve 16. This mountingvsleeve has .aA urality of sets of arcuate slots distributed along the sleeve, there being three arcuate slots 17, 18 and 19 in each set that are arranged circumferenseparated relation;

Each sleeve is thus middle slot 18 of each circumferential set and Wing portions 23, 24 which respectively enter the end slots 17, 190i such set. T-he sleeve is formedwith .a set of fingers 25 upon one side, a set of fingers 26 upon the y other side, the fingers of one set interleav-l ing with the fingers of the otherA and the fingers of both sets tapering or otherwise formed to exert pressure upon one another longitudinally of the sleeve upon contraction of the ngers whereby the portions of the plates that are in the arcuate slots between the fingers are gripped into firm as` sembly with the sleeve.

threaded upon the other end of the shaft 28 and presses against the adjacent end of the mounting sleeve whereby the assembly of the mounting sleeve and shaft is completed. The shaft 28 projects through the mounting plate 2. A knob 32 has a stern 33 which is threaded upon the projecting front end of the shaft 28. The stem 33 serves to hold the bearing portion 34 between it and the nut 31 this bearing portion turning within the plate 2'. There is a rotative mounting for the `mounting sleeve when the condenser Side=carried by the mountingsleeve is to be adjustable, but the invention is not to be thus limited. v While I ha've herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made Without de- 1 arting from the siprit of my invention, but avingv thus described my invention I claim as new and desire to cure by Letters Patent the following:
