Application Med Il areh 11, 1925. Serial No. 14,815.
This invention relates to electrical devices, and more particularly to electrical condensers.
An object of this invention is the production of a condenser, the component parts of which are exceedingly cheap and sim le, the arrangement of the parts being such at the matter of replacement andA repairs is reduced to a minimum.
Another object of 'this invention is the production of a condenser .which is compact, durable and ecient, and so designed that it will withstand rou h usage.
Another object othis invention is the production of a condenser so desi ned and constructed that it will not over eat and thus cause a break down.l
A further object of this mvention is the production of a condenser, having a unique terminal so constructed and arran ed, and
' mounted within the wall of the casing, that undue heatin around the terminal is avoided. Yet a furt er ob'ect of this invention is the simple yet dura le manner in which the condenser casing is formedv and mounted, all
unnecessary lparts being eliminated. With these and other objects in view which may be incident to my improvements2 the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements..compris1n`g my invention, ma be varied in construction, proportions an arrangement, without departing from the spirit and Isco e of the appended claims.
f In order, to make my invention more clearly understood, I have shown in the accompanying drawings means for carryin the same into practical effect, without limiting the improvements` in their useful applications to the particular constructions, which for `the pur ose of explanation, have been made the sub]ect of illustration.
'In the drawings forming a part of this specification: I p
Figure 1 is a top plan view illustrating the condenser casing, the condenser sectionsV and compression plate being shown in dotted lines; l y Y Fig.4 2 is a-vertical` sectional view taken on vline 2 2 of Fig. 1;
Referring by numerals to the drawings, 1
representsa metallic base having a number of apertures 2 distributed an equal distance apart adjacent to the edges. Mounted upon the base is a glass casing 3 having an integral rifght angular flange 4 in which are a number o apertures 5. The casing is further provided with a central aperture 6 having a shoulder 7 formed therein, the object of which will hereinafter appear.
The flange 4 of the casing 3 bears against the base 1, the apertures 5 in the flange registering with the apertures 2 in the base. A
gasket 8 is interposed between the flange and base, and studs 9 pass up throu h the registering apertures 2 and 5. uts 10 are mounted upon upwardly protruding ends of the studs 9 and one of the studs 9 is further provided with a nut 11 adapted to clamp between itself and-the nut 10 a lead, notl shown.
Mounted upon the base 1 within the casing 3 are corresponding condenser sections 12.
plate 13 w ich supports like condenser sections 14 mounted immediately above the secltions l2. Bearing upon the sections 14 is a plate 15 having its respective ends projecting beyond the condenser sections and provided with apertures 16, which register with op o'- sitely disposed apertures 17 in the base. r-
. responding bolts 18 pass upward through the registerin apertures 16 and 17 and are provided wit nuts 19. By means of this construction a uniform pressure is exerted on the condenser sections.
A split sleeve 20, of any suitable non-conduetive material, having a flange 21 and an internal rib 22, encircles a terminal plug 23 having a groove 24 which receives the rib 22.
, Bearing u on these condenser sections is a The sleeve 20, with the plug 23 mounted therein, is fitted into the aperture 6, the iiange 24 on the sleeve bearing against the shoulder 7, the lower end of the sleeve bearing against a gasket 25 fitted over the downwardly projecting end of the plug 23.
The plug 23 is threaded into a non-,conducting sleeve 26, the upper end of which bears against the gasket 25. The sleeve 26 extends downwardly through an aperture 27 in the plate 15 to a position slightly above the plate 13 suiiicient to allow for expansion and contraction. A braided copper wire 28, which passes through the sleeve 26, connects the plug 23 to the plate 13. The upper end of the plug projectlng through the sleeve 20 is threaded to receive a nut 29, and upon the top of the plug is a set screw 30 for attaching a lead, not shown.
In Figs. 5 and 6 I have shown a modified form wherein the base 1 and casing 3 take a circular form in lieu of the form shownin Figs. 2 and 3, hence the plates 13 and 15 would also take a circular form in order to conform with thel configuration of the casing.
The difference involved is that in this 'formv a greater number of condenser sections 12 may be employed, also the compression bolts 18 are interposed alternately between the condenser sections, which would tend to more evenly distribute the pressure. In this form the non-conducting sleeve 26 is omitted. The terminal plug 23, which is connected to the plate 13 by a braided copper wire 28, has a flange 31. A mica washer 32 is slip ed over the plug 23, and bears against the ange 31. The plug 23 is passed up through the aperture 6, the washer 32 bearing against the under surface of the casing wall.
A mica washer 33 is fitted over the protruding end of the plug and bears against the outer surface of the casing wall. A nut 34 is threaded on the protruding end of the plug and bears against the washer 33. 'By tightening-'the nut 34, the terminal plug is secured in place. Fitted on the protruding end of the terminal plug over the nut 34 is a nut 35 adapted to clamp between itself and the nut 33 a lead, not shown.
Figs. 4 and 7 are diagrammatical illustrations of two distinct types of condenser stacks, either of which may be employed in the construction of the condenser sections. The form shown in Fig. 4 consists of a plurality of condenser plates 36 and ielectric sheets 37. `The condenser plates are nected in groups 38 in conjunction with intermediate condenser plates and dielectric sheets. The form illustrated in Fig. 7 comprises a plurality of condenser plates 39 and dielectric sheets 40 connected in series.
With the arrangement shown in Figure4 some of the plates are isolated constituting in eiect floating capacities, and if this arrangement is adapted for either the sections sire to secure by Letters Patent is:
of connecting the conductive plates of the condenser may be employed.
While Iv have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not conine myself to the precise details of construction herein set forth by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing trom the spirit of the invention, or exceeding the scope of the appended claims. Y i
Having thus described the various features of my invention, what I claim as new and del 1` In a condenser, a base, a casin mounted upon the base, a plurality of con ensersections mounted upon the base within the casing, a plate intermediate the condenser sectier of condenser plates bearing against the.
base, a top plate bearing against the top tier, means between the baseand top plate for-exerting a pressure, a terminal in the wall of the casing, and a connection between the terminal andthe intermediate plate.
3.` In a condenser, a base, a casin mounted upon the base, a plurality of con enser sections mounted upon the base within the casing, an intermediate plate between the` condenser sections, a top plate bearing against the condenser sections, means for exerting a pressure between the base and top plate', a terminal mounted in the wall of the casing, a sleeve mounted upon the inner end of the terminal, a braided wire extending through lminal passing through an opening in said plate.
