FILLING DEVICE FOR BATTERIES AND THE LIKE.

a ueanoa filed March 5, 1921. Serial no. 449,675.

To all whom it may concern Be. it known that I, Or'ro H. Korea, a citizen of the United States. residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in a Filling Device for Batteries and the like, of which the following is a specification.

My invention relates to a filling device for batteries and the like, and my invention particularly relates to improvements in filling devices used for filling storage batteries with water in sufiicient quantity to bring the normal water level to the proper height. above the plates within the battery.

The object of my invention is to provide a device having a liquid container which may be placed in an inverted position, resting upon the battery, having flexible tubes extending a predetermined length into thev battery, which tubes will not injure the battery plates, as the weight of the container rests upon the top of the battery and not upon the plates; a further object of my invention is to provide means for shutting off the flow of water through the tube from the container during the placing of the container into position upon the battery and also when removing the same from the battery, whereby water will not be spilled over the top of the battery, and a still further object of my invention is to provide a device which is simple in construction and operation, and which can be manufactured at a low cost.

Referring to the accompanying drawing, Fig. 1, is a perspective view of myimproved filling device; Fig. 2, is a side elevation of the filling device secured in a container and shown in the inverted position resting upon a battery, partlyshown in section; Fig.3, is a transverse section on line 33 Fig. 2; Fig. 4, is a vertical section on line 44 Fig. 3; Fig. 5, is a side elevation of a different form of stopper having finger recesses formed on opposite sides thereof for impinging the tubes, and Fig. 6 is a transverse section on line 6-6 Fig. 5.

In the accompanying drawings, in which like reference characters refer to like parts; 1 represents the stopper having a body portion 2 adapted to be tightly fitted into the mouth 3 of a container 4. The stopper 7 is provided with a head portion 6 connected with the body portion ,2 by a connecting member 7 which latter is a suflicient length to permit the stopper having a recess 9,

mensions so that a finger may be placed therein and compress either of the

tubes

12 and 13 extending longitudinally through the stopper.

The

tubes

12 and 13 are sealed, or tightly fitted, into the apertures formed through the body portion 2 of the stopper, to prevent air entering the container 4 around said tubes.

The connecting member 7 of the stopper is provided with a lug 15 positioned opposite to'the finger recess 9. Said lug 15 forms a ridge over which the tubes are slightly curved, as shown in Fig. 4, and against which the tubes may be more readily compressed by the finger to close the passageway through the tubes and thus shut ofi the flow of air or liquid through the same.

The head portion 6 of the stopper is adapted to rest upon the flange 16 formed on the top of the storage battery 17, and support the container 4 in an inverted posi- .tion with the ends of the

tubes

12 and 13 extending through'the filling opening 18 of the battery. The end surface of the head 6 is provided with radial grooves 20 to allow air to pass between the head and the battery flange 16.

The water tube 13. is out off the proper length beyond the head 6, so that the end of said tube will just touch the plates 22 of the battery and the air tube 12 is then cut as much shorter than the water tube 13 as it is desired to have the water level normally maintained above the plates.

Figs. 5 and 6, show a modified form of the stopper in which recesses 25 and 26 are formed opposite each other and extending through the stopper, exposing the tubes from either side of the stopper, thus permitting' the tubes to be compressed between two fingers, which may readily be inserted ger is placed up one or both of the tubes to shut off the flow of air or water through the tubes and the receptacle can then be inverted and placed on the top of the battery with-the tubes extending into thefilling opening; the finger is then removed and air enters the receptacle from the battery through the shortertube which permits the water to flow through the longer tube until the level of the liquid in the battery seals the mouth of the air tube. The fingers are again placed upon the tubes to prevent the water from dripping over the battery when the container is being removed from the battery. 7

Having thus described my invention I claim and desire to secure by Letters Patent:

1. A filling device comprising a stopper having a body portion, a head portion, a connecting member between the body portion and the head portion, flexible tubes extending through the said body portion and the head portion and projecting-predetermined leng'ths'beyond the head portion, whereby the head portion will limit the distance the tubes may be inserted into a receptacle, and said connecting member being constructed to permit the tubes ,to be compressed between the said body and head portions. 2. A battery fillin device comprising a stopper adapted to efitted intoa liquid container, said stopper having a portion thereon adapted to rest upon a battery adj ac'ent to the filling aperture formed therein, a tube extending through the stopper for the passageof air into the container and adapted to extend into the battery aperture and terminate at the normal liquid level of the battery, a second tube extending through the stopper for the passage of liquid into the battery and terminating below the said normal liquid level, and said last mentioned tube being made of flexible material so as not to injure the interior of the battery. o

3. A battery filling device comprising a stopper adapted to be fitted into a container, tubes extending through the stopper for the passage of air and liquid and adapted to be inserted into the filling aperture of a battery, said stopper having a portion adapted to rest'upon the outside of the battery to limit the distance the said tubes may be inserted into the battery and said tubes being niade of flexible material so as not to injure the battery plates.

4. A filling device comprising a container for holding a supply of liquid, tubes for the passage of air and liquid to and from the container, a member upon the container located adjacent to the said tubes forming a rest for supporting the container upon the top of a receptacle having a filling aperture formed therein, said tubes extending 'a predetermined length beyond the support ing surface of the said rest member to limit the distance the tubes may extend through the said aperture into the receptacle, and said member having an open portion formed therein exposing a portion of the tubes whereby the tubes may be compressed at a point between the container and the rest end of the said member to shut 0d the flow of liquid.

In'testimony whereof I aflix my signature.
