Patented 'June 24, 1930 UNITED STATES PATENT! OFFICE PAUL M. MARIO, OF BROOKLYN, NEW YORK, ASSIGNIOR TO WILLARD STORAGEYBATTERY COMPANY, OI CLEVELAND, OHIO, A CORPORATION OF WEST VIRGINIA RADIO BATTERY CONSTRUCTION Application filed July 5, 1924- Serial No. 724.,833.

simple and tight joint to prevent leakage or splashing.

Another object of'the invention is to pro vide a combination and arrangement of parts which are extremel simple in their construction and assem ly so that the battery can be manufactured at a very This invention is an improvement over the radio battery construction shown in' my patent No. 1,485,282 issued February 26, 1924.

The invention is illustrated in the drawings, of which- Figure 1 is a sectional view of the upper end of a batteryshowing' the closure construction;

Fig. 2 is a plan view of the battery;

Fig. 3 is a sectional view through one form of closure cap; Y

Fig. 6 is a plan view of the cap shown in Fig. 5; and Fig. 7 is a sectional view through a still further form of closure cap.

The forms of the invention shown in the drawings are preferred forms, although it is understood that modifications in the construction andarra'ngement of the parts and.

' in the character of the materials used may be adapted without departing from-the spirit of the lnvention as set forth in the appended claims.

.In its general aspect the mvention contemplates the rovlslon of a parts to form t e. closure for t e container of a radio battery, which will be few in' number and yet so efiiciently related as to form a strong and durable type of closure low cost and 15 yet be very strong and durable.

plurality. of

capable of being manufactured at an ex; tremely low cost To this end I provide a cap portion of some pliable material such as soft rubber which is disposed across the top of the container and provided with passages through which the terminals of the electrodes to a battery extend. This cap is held in place by a ring which embraces the end of the container, said ring being provided with means for engaging thetop of the cap around its periphery to hold the rap firmly in place on top of the container.

The invention further contemplates the combination with the cap of soft pliable material such as rubber, of a layer of stifier material such as hard rubber, which may be connected thereto in any suitable manner" such as by vulcanization. This reenforcement is intended for the purpose of reventing the pliable cap from sagging or ending under the weight of the parts connected thereto whenever the container is of considerable size.

The invention still further contemplates the provision of certain forms of thecap through the cap, in order to insure that no v leakage of the liquid occurs.

In the referred forms of the invention as shown 1n the drawings, I provide'a container 1, which is preferably of glass, the upper end of which is provided with threads 2 adopted to be engagedby a sleeve orring or cover member 3, this ring being provided with a flange 4 which extends inwardly a short distance sufiicient to extend over the u per edge of the. cap. This flange is adapted, as the ring 3 engages with the .u per end of the container 1, to bearon t e periphery of a closure cap 5. This closure cap .is preferably made of any suitable 10o pliable material such as soft rubber, although, of course, it may be made of hard rubber. This cap is provided with nipples such as 6, preferably formed integral with the cap and of substantial height compared to their width. These nipples are pierced to permit the passage therethrough of the upper ends 7 and 8 of the electrodes of the battery.

In some forms of the cap I provide a dependent flange such as 9 which fits snugly within and against the inner walls of the container 1 so as to further insure 'a tight joint between the cap and the container. In certain forms of the cap I also provide a recess 10 cut out of the under surface of the cap so that liquid which may be formed on the upper ends of the electrodes will have a longer path to travel to get out through the joint than otherwise, and in this respect the liability of leakage is further reduced. The cap 5 is provided with a filling aperture 11 and a vent hole 12. I 1

In another form of the invention, shown in Fig. 4, the container 13 is provided with threads 14 engageable with a ring 15 having an inwardly extending flange 16 adapted to bear on the periphery of a cap 17, preferably of soft rubber. This cap, however, is provided with a reenforcing layer 18 of, preferably, stifl'er material, such as hard rubber,

which is preferably vulcanized thereto. This cap 17 is also provided with nipples 19 through the

upper ends

20 and 21 of which the battery electrodes extend. It will be noted in Fig. 4 that the lower edge of the cap 17 extends straight across the top of the container.

In the form shown in Fig. 5 the cap 17 is provided with a layer 18 of reenforcing material, and nipples 19. In this form, however, the cap is provided on its under surface with a dependent flange 22, as well as a recess 23 on its under surface. This recess is formed for the same purpose as the recess 10 previously mentioned. The cap 17 1s also provided with a filling aperture 24 and a vent hole 25;

In the form of the cap 17 shown in Fig. 7 the lower edge of the dependent flange 22 extends straight across without being provided with a recess 23.

The reason why the layer of reenforcing material, such-assrubber, is'applied'or vulcanized to the cap of softermaterial is to .give it the proper stiffness whenever the cap is to be used on the ends of containers of substantial diameter where the liability of a vsoftrcap to sagor bend is greater than/with A smaller sized containers.

In the general contem lation of the invention, therefore, it can" e observed. that I provide a cap which is laid on the upper. end of the container and, held thereon by the engagement' therewith of part of a. ring which embraces the u per end of the container, this part pre erably being an inwardly extending flange. It will be noted, however, that this flange extends only far enough inwardly to engage the edge of the cap and does not interfere with the area 00- cupied by the nipples, so that the ring can be screwed on tightly against the cap without affecting the position of the nipples. Therefore the closure can be made very tight without the liability of the ca being twisted. The elimination of this liability prevents the parts of the battery connected to the cap rom getting out of alinement.

What I claim is 1. A battery construction, which comprises a cap of pliable material adapted to be placed across the open end of a battery container and to rest on the upper edge thereof, a dependent flange formed on the under surface of the cap, said flange adapted to provide a shoulder to bear against the inner upper edge of the container to form a tightjoint therewith and means engageable with' said cap to force the latter into contact with the upper edge of said container.
