J., asslgnor t the United States of America as represented by the Secretary of War Application May 10, 1945, Serial No. 592,952.- 4 Claims. (01. 136-133) (Granted under the act of March 3, 1883, as
amended April 30, 1928; 370
The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.
My invention relates to primary cells and more particularly to sealing means for said cells.
An-object of my invention is to provide improved sealing means for a cell of the metal oxide-zinc type.
Another object of my invention is to provide a metal disc adapted so as to compressibly seal itself with a grommet of resilient material.
Another object of my invention is to provide a grommetof resilient material-adapted so as to form a compressible seal between a metal disc and the free edge and shoulder of a cell container. Another object of my invention is to'provide a metal disc adapted so as-to form the negative terminal of a cell.
-A still further object of my invention is to provide a metal disc adapted so as to make an electric contact with the anode of a cell.
A primary cell is known in the art comprising an anode in the form'of a strip of corrugated zinc foil contained within a roll" of alkali-resistant material, a depolarizer cathode of reducible mercuric oxide, an electrolyte comprising a solution of potassium hydroxide saturated with zinc oxide, said-electrolyte being held absorbed within said roll of alkali-resistant absorbent material, a container for said cell parts of iron or steel, said for said container which forms the cover and the negative'terminal of said oeIL'said zinc top being fitted into an elastic Neoprene ring or grommet, saidzinc top' and Neoprene ring-assembly resting on the shoulder formed The mentioned cathode is disposed at the bottom of'the container, with the anode above it, the two electrodes being separated by a porous disc. Theherein above described cell under test was observed to have a tendency to leak or to have a certaina'mount-of creepage of the potassium hydroxide electrolyte. My invention will eliminate saidleakage and prevent the creepage of the potassium hydroxide electrolyte.
My invention will be more fully understood from'the following detailed description taken in connection with the accompanying drawing, wherein I have shown a preferred embodiment thereof.
secure by Letters Patent Referring to the drawing:
Fig. 1 is a sectional perspective view of the metal disc,
Fig.2 is a sectional perspective view of the grommet, and
Fig. 3 is a. sectional view of the cell assembly.
Referring to Fig. 1, my device consists of a metal disc l0, such as a zinc disc, with a downwardly extending skirt H. The grommet l2 in Fig. 2 is inwardly beveled at l3 and M. The metal disc IU of Fig. 1 fits closely in the circular channel l5 of the grommet l2 and the downwardly extending skirt ll of Fig. 1 fits closely through ing skirt ll peened outwardly, and also upwardly against the lower portion of the grommet. Thus, a channel is formed in the disc, into which channel the inner part of the lower portion" of the each of these coacting members is sealed into the channel of the other, which construction provides a very eiiective double seal. The metal disc-grommet assembly I! rests compressibly upon the shoulder ll! of the container IS. The peened portion of the downwardly extending skirt ll of the metal disc I0 makes close electric contact with anode 20. The free edge 2| of the Having thus described my invention I desire to and claim:
1. In a primary cell comprising a metallic container, electrodes and an electrolyte within the container, the combination of a metallic disc on one of the electrodes, a grommet insulating the disc from the container, said disc and. grommet having opposed annular interfitting channels each sealingly receiving a portion of the other.
2. In a primary cell comprising a metallic container, electrodes and an electrolyte within the container, the combination of a metallic disc on one of the electrodes, a resilient grommet insulating the disc from the container, said disc and grommet having opposed annular interfitting channels each sealingly receiving a portion of the other, the upper marginal portion of the container being pressed inwardly and downwardly onto the grommet.
3. In a primary cell comprising a metallic container, electrodes and an electrolyte within the container, the combination of a metallic disc on one of the electrodes, a resilient grommet insulating the disc from the container, said disc and grommet having opposed annular interfltting channels each sealingly receiving a portion of the other.
