The spring 15 is free or floats comprehended in or is a component of one between the members 1 'and 13, for it is not or more condenser units of the receiving secured to either of those members or to any set. other member.

On the inner side of the panel 1 is the ledge Upon the part of the shaft 10 overhanging member 2 of sheet metal, having the downbeyond or extending to the right of the bearwardly extending flange 3 secured, as by ing'member 4, as indicated inFig. 1, are spot-Welding, to the panel 1. secured one or more parallel conducting Upon the ledge member 2 may be carried leaves or plates 17 constituting the rotatable other devices or elements of the radio rearmature assembly or rotor element of the or the like.

Co-acting with the rotor plates 17 are the stator plates or leaves 19 disposed substantially parallel with each other and suitably s aced to permit interleaving therewith of the rotor plates, as well understood in the art.

The stationary armature plate assembly or stator comprises the plates 19 through apertures in which extend the rods or bolts 20. Surrounding each of the rods or bolts 20 and serving as spacers for the plates 19 are the Washers 21. The nut 22, threaded upon each of the rods 20, serves as an abutment .between which and a washer 23, held by a nut 24, the plates 19 and washers 21 are confined.

The several rods or bolts 20 may be di rectly and individually secured to the panel or plate 1, but, as indicated, and particularly when the rotor is in electrical communication with the metal panel 1, there is utilized for each bolt 20 an intervening member 25 of insulating material secured to the panel 1 by any suitable means, as for example by screw 26.

' The members 25 are preferably threaded onto the bolts or rods 20 as indicated, and the osition of the stator structure lon itudinally of the axis of the shaft 10 is ad ustable and determinable by the nuts 27 threaded upon the bolts or rods 20 and abutting hgainst' the members 25.

The structure above described is broadly of the character disclosed in the aforesaid application, particularly in that the stator structure is supported upon or secured to the panel 1 independently of the mounting or support of the rotor element, whereby the panel 1 is a component part of the condenser unit, and whereby the positions of the rotor and stator elements with respect to each other are determined by their re spective independent attachments to the panel 1. In the structure herein described and claimed the stator element is attached to the panel 1 at one or more points, each of the attachments is adjustable to efl'ect adjustment of distance of the stator structure from the panel 1 and, preferably, each attachment comprises a member of insulating material for supporting and determining the distance of the stator structure from the panel 1 and for insulating the stator structure from the panel.

What I claim is:

1. The combination with a paneLof rotor and stator elements of a condenser, a support for said rotor element on said panel,

said stator element comprising a rod, plate structure carried by said rod in co-operative relation with the plate structure of the rotor element, and means securing said rod tosaid panel independently of said rotor support, whereby said panel is included in a condenser unit with said rotor and stator elements.
