id WM ATTORNE Y Patenta& Nov. 10, 1931 PATENT OFFICE EDWARD L. BOWLES.- OF 'WA'I'EE'LIOW'N' MASSACEUSETTS CONDENSER Application filed Iarch 16, 1925. Serial- No. 15,769.
The present invention relates to electric condensers, and more particularly to fixed 'condensers A chief object is to provide an improved fixed condenser that shall be easy and cheap to manufacture and very eficient in operation.
Further objects' and advantages of the invention will be in part obvious and in part 'specifically mentioned in the description contained hereinafter.
In the accompanying drawings, Fig. I is a plan of a condenser constructed according -to a preferred embodiment of the present invention; Fig.II is an elevation of 'the same; Fig. III is a diagrammatic view, in section, illustrating the preferred Construction of a condenser manufactured according to the present invention; Fig. IV is a perspective view of several conducting and insulating sheets of a condenser arranged according to the pireferred embodiment of the'present inventon; Fig. V is a diagrainmatic section taken upon the line V-V of Fig. I, looking in the direction of the arrows; Fig. VI is a similar section taken upon the line VI-VI of Fig. I; and Fig. VII is a plan of a modified insulati'ng plate.
The preferred condenser of the present invention comprises a stack of alternately disposed, thin, conducting sheets 20 and 22, like tinfoil, and thin insulating sheets 24, like mica. It is preferred to have the sheets discshaped, with the diameter-'s of the insulating discs somewhat lar er than the diameters of the conducting iscs. The conducting sheets 20 are each provided with diametrically opposed lips 14 and 16, and the conducting sheets 22 are each provided with similar,
9 oppositely disposed lips 15 and 17. The li s 14, 15, 16 and 17 project beyond the perip eries of the insulatng sheets 24, as illustrated.
` The lips 14 of the group of sheets 20 are all disposed in alinement, as shown in Fig. V,
and, naturally, so are the lips 16. The lips 15 and 17 of the group of sheets 22 are similarly alined, as shown in Fig. VI. The lined lips 14 are midway disposed between the lips 15 and 17, the lips 15 mdway between the lips 14 and 16, and so on, the lips being staggered iind'icated at 30, 32 and 34, 36, respectively,
bent at rightangles to the body portion. The body portion 26 is in engagement with the' plate 5 and the body portion 28 in engagement with the plate 6. The arms .30 and 32 respec- I tvely contact with the lips 14 and 16, and the a'rm's 34 and 36 with the lips 15 and 1. Elec-' trical contact is thus established between each holder and the sheets 20 or 22, as the case may be, of one of the roups. Tle arm 30 is provided with an en portion 38 that is bent parallel to the body portion and pressed into intimate engagement with the plate 6 at a time when the stack is under pressure. Thearm 32 is similarly provided with a similarly bent end portion 40 that is pressed into intimate engagenent with the plate G. The arms 34 and 36 are likewise provided with end portions 42 and 44 that are pressed into intimate contact with the plate 5.
ach holder thus presses a ainst both sides of the stack of sheets and nterposed plates 5 and 6, eflecting a firmer holding action. The holding action is increased by reason of the fact that the end portions of the arms are arcuate, which tends to prevent the end portions opening out easily when the abovementioned pressure upon the stack is relieved. The holding pr'essure of the holders tends, therefore, to become eq'ualized throughout the area of the condenser. A very compact, easily manufactured condenser is thus provided at small cost.
Electrical connection to the condense' may be made by means of terminals 7 and 8. These may consist of binding posts, projecting rods and the like, but it is preferred to make them of lugs that are sti-uck or bent up out of the body portions of the holder. It is, of course,
essential to have the holders insulated from each other, and the insulating plates 5 and 6 fulfill this requirement admirably. They should be made relatively thick, so as to be stifl' enough to transmit the 'pressure of the holders to the stack. If greater stifl'enn action is desired, metal plates may be use instead of the insulating plates 5 and 6, provided that insulating barriers are provided between them and the holde'rs. To obviate any tendency of the holders slipping upon the stack, and thus possibly coming 'into contact with each other, one or both of the insulating plates 5 and 6 may be slightly flattened alon their periphery, as shown at 46, Fig. VII, and the holders may be bent against the flattened po'tions.. The fiattened portions 46 may be provided by making four tangential cuts, ninet degrees apart, along the periphery of the p ates.
It will be understood that the invention is v not limited to the exact embodiments thereof that are illustrated and described herein, but that modifications may be made by persons skilled in the art without departing from its spirit and scope, as defined in the appended claim. v
What is claimed is A condenser comprising a stack of alternately disposed disc-shaped conducting layers and insulating layers, the conducting layers each having oppositely disposed lips projecting beyond the insulatng layers, the conduct ing layers being arranged in two groups with the lips of each group in alinement with each other and out of alinement with the lips of the other group, the conducting layers of each group alternating with the conducting layers of the other group, two conducting sheet-metal 'holders between which the stack is disposed, and two insulatin disc-shaped members nterposed between t e stack and the holders, the holders each having a body portion in engagement with one of the members and two arcuate arms bent at right angles to the respective body portions along a substantial portion of the circumference of the condenser, each arcuate arm of each holder being between the two arcuate arms of the other holder along the circumference of the condenser, the bent-up arcuate 'arms of each holder contactingwith the oppositely disposed lips of one of the groups, and the free ends of the bent-up arcuate arms being' bent along the crcumference of the condenser parallel to the body portion into tight engagement with the respective insulating members, whereby opening out or bending back of the bent-over arcuate arms is prevented by the curvilinear form into which the sheet-me'. al holders are bent, the holders being insulated from each other.
In testimony whereof, I have hereunto subscribed my name.
