VARIABLE connnnsnn'.
My invention relates to the construction of variable condensers comprising two sets of plates in which the plates of one set are interleaved with those ot another set and are mounted to be moved relatively thereto. The object ot' my invention is to provide an improved construction oi the condenser- V2---2 of Fig. l; and Fig. 3 is a detail ot' oneA of the plates drawn to a larger scale.
The condenser comprising my invention is built up of two sets ot' substantially semicircular plates, a, stationary set l and a rotatable set 2, theplates ot' the two sets being interleaved and relatively vmovable without contact. The plates comprising each set are identical. Each stationary plate is provided with three openings 3 of a size to receive the securing means, to be describedl later, and
the material surrounding each opening isA expanded to forni oppositely extending flanges 4 and 4: or what might be termed a double cup with portions extending equi-distantly from both sides of the plate. The platesmay be conveniently given the desired torin by apunching operation, the dies being so made that the two oppositely extending annular anges formed in theplates have a height equal to one-half 4of the desired spacing of the plates. To build up the stationary element of a condenser having plates so toi-med, the individual plates are stacked up with every alternate plate inverted and with the openings 3 in alinenient. The stack thus formed is then placed between the two insulation plates 6 and 7 and the three securing bolts 8 passed through thealining openings in the condenser plates and through corresponding", openings in the insulation lates. A suitable spacing washer 9`inay be used above the top condenser plate and the set firmly secured together and to the insulation plates by nuts vl0. It will be noted that .by giving each plate a double cup or double 'flange formation such as illustrated and by plates.
arranging the plates with each alternate plate inverted, corresponding flange por tions ofgadjacent plates bear against cach other. lt is unnecessary therefore that the flanges be given square edges as would be the case were the flanges to extend to one side only of tlie plates and the plates were to be stacked up without reversing alternate plates. With this construction the plates sci lii'inly against each other with a predeterniiued and accurate spacing.
The. plates comprising the rotatable set are each provided with a single concentric opening ll with the material surrounding the openings Jformed up into oppositely extending annulaitlanges just like the stationary rlhcse'are also stacked up with each alternate plate inverted and secured together on a spindle l2 by being clamped between a sleeve lland a nut lil. A knob 15 and dialv 16 are shown mounted onl the spindle l2 as is usual.
While I have described only one einbodiment of my invention, I do not wish to be limited -to the particular form shown and described as it will be apparent that many modilications therein may be made without l departing from the scope of my invention as set forth inthe appended claims.
What I claim as new and desire to secure by Letters Patent of the :United States, is
1.111 a variable condenser, a series of parallel plates having alined openings ther-ein, a clamping member extending therethrough, said plates having integral spacing portions adjacent said openings and extending laterally from opposite sides oitl the plates, the spacing portion on one side of each plate being further from the axis of the clamping element than the spacing portion on the opposite side.
2. In a variablecondcnser, a series of parallel plates having alining apertures therethrough and clamping` means extending therethrough, said plates having spacing means comprising annular llangesextending on Aopposite -sidesthereof and surrounding said clamping means, the diaineter of the flange on one side ot' each plate being greater than the diameter of the flange on the opposite side of the same plate.
3. In a variable condenser, a series ot" parallel plates having alined openings therein, a clamping rod extending therethrough, said plates having spacing means comprising a pair of integral concentric an4 nular flanges formed therein around said openings, one of said flanges projecting at one side of a plate and the other projecting at the opposite side thereof, said flanges having a height substantially equal to onehalf the distance between adjacent plates, the diameter of the annular flange on one side of each plate being greater than thediameter of the annular flange on the opposite side of the same plate.
4. In a variable condenser, a series of parallel plates having alined openings therein, a clamping rod extending through said openings, each plate having spacing means comprising a pair of annular flanges formed integral with thel plate around the axis of each opening, one of said .flanges projecting beyond one side of the plate and the other` projecting beyond the opposite side of the plate, the diameter of the annular flange on one side of each plate being lgreater than the diameter of the annular flange on the opposite side of the same plate said flanges forming spacing elements for the plates. y
5. An electric condenser including a plate havinga boss on each side of the plate, each boss being integral with the plate and formed from the metal of the plate, a portion of the original surface of the plate appearing on each boss in a plane parallel to the plate said boss elements serving as spacing elements for the plate. f
6. An electric condenser including a series of plates, each plate having a boss on each side thereof, each boss being integral With the plate and formed from the metal of the plate, a portion of the original surface of the plate appearing on each boss in a plane parallel to the plate, said plates arranged with the axes of the boss elements coinciding and parallel With the axis of the capacitor, the boss on one plate bearing against the boss of the adjacent plate, said bosses serving as spacing elements for the plates, a shaft extending through said boss elements, the axis of the shaft being parallel 'to the axis of the Capacitor and means upon the shaft for securing said plates together by pressing the boss elements together.
7. An electric. condenser including a plate, a boss formed on each side of said plate from the metal of the plate, the metal ofthe/plate being folded in one direction along the longitudinal axis of the plate and then folded back in the opposite direction along the axis of the plate and crossing the central plane of the plate to the opposite side of the plate and there folded again along a plane at right angles to the axis of the plate. v
8. AnA electric condenser including a plate, a boss formed on each side of said plate from the metal of the plate, the metal of the plate being folded in one direction along the longitudinal axis of the plate and then folded back in the opposite direction along the axis of the plate and crossing the plane of the plate to the opposite side of the plate and folded again on the last mentioned side along a plane at right angles to the axis of the plate, said boss being in the form of a cup, the plane through the center of the plate and parallel to the plate cutting the cup between its rim and bottom, the axis of the cup being parallel to the axis of the plane.
In Witness whereof, I have hereunto set my hand this 25th day of September, 1923.
