Application September 21, 1934, Serial No. 744,985

7 Claims. (Cl. 221-25) My invention relates to improvements in battery fillers, and particularly to a device of this character intended and adapted to be used to contain distilled water, and to readily and easily be manipulated to supply water into the usually relatively small openings of the battery, without spilling or overflowing of the water.

An object is to provide a device of this character including a main container of not readily frangible material, which is ordinarily more or less opaque, together with means by which the quantity of water or otherliquid that is in the container can be readily ascertained.

Another object is to so construct the parts that a discharge tube, readily handled and manipulated to properly direct and to control the supply of water or liquid is included and is, associated with the container in a manner to give facility and to avoid the possibility of damage in use.

Still another object is to provide a container with an opening through which liquid is readily supplied for filling, and which opening and the adjacent portions of the container are so constructed that a. hydrometer or other testing instrument is readily and conveniently held in place therein and is protected against damage or breakage, when in place, or when being inserted or removed.

Yet another object resides in so constructing, positioning and assembling the parts that the container structure, of not readily frangible material, will afford protection. to a gauge tube and to the filler tube to protect the same when the device is in use. I

With these and other objects in view, which will be apparentto those skilled in the art, my invention includes certain novel features of con struction and combinations of parts which will be hereinafter set forth in connection with the drawings and then pointed out in the claims.

In the drawings:

Figure l isa view in perspective illustrating one adaptation'of the present invention.

Fig. 2 is a vertical sectional view through the struct Fig. 3 is a vertical sectional view taken substantially at right, angles to the showing in Fig.

:2, and with a hydrometer in place.

, Fig. dis a fragmentary detail sectional view. The container, generally indicated at i, is made of hard rubber, vulcanite, or other readily molded and substantially non-frangible or not readily frangible material, preferably possessing a degree of elasticity or yieldability to prevent fracture or breakage due to dropping, knocking against objects, and other shocks or blows encountered in use. This container, preferably of a size to hold a. quantity of water suiiicient for several battery fillings, has in practice been made to have a ca 5 pacity of substantially one gallon, although not limited to such capacity. The container is advantageously shaped to be substantially cylindrical in its body portion, with the upper portion tapered to be of reduced size, as indicated at 2, l0 and of truncated cone form terminating in a relatively wide opening at 3.

This opening 3 is made wide to permit more ready molding and formation ofthe body portion, and more ready removal of any mold sections that may be required; and, the opening 3 is provided with an internal annular groove 4.

A funnel or neck 5, also preferably of tubular truncated cone shape,has an outwardly projecting flange 6 at its flared end to fit within the groove 4, and the edge around the open mouth I is preferably rounded and smoothed off and is of a size to receive and hold the bulb portion of a hydrometer or other, testing instrument, of the usual syringe type, with the usual glass barrel and other frangible portions of the hydrometer suspended centrally within the body or jug portion I, after the manner illustrated in Fig. 3.

The body or jug portion is preferably rounded up in its middle portion on the inside of the bottom to thus drain toward a lateral opening 8, formedthrough the wall of a recessed portion 9 of the body I, and it is preferable that bosses or knobs M be provided on the bottom portion at suitable points to serve as feet or rests. These bosses or knobs give increased material at the points where the greatest shock is ordinarily received by the body or jug portion when set down or dropped, and due to their rounded form and the more or less elastic and yielding nature of the material, these bosses will function to reduce and absorb such shocks. V

The body portion or jug l is preferably made with ahandle ll extending at one, side ofthe portion 2, so that as the handle isgrasped the body or jug portion will be held and will suspend, by balancing of the weight, insubstantially upright relation to avoid spilling the liquid through the open top at 'I. It is perhaps preferable that rib portions l2 be provided internally in the body '5 portion to reinforce and strengthen the walls thereof where strain is placed by the handle I l, and at any other desired points, and it is also perhaps desirable that circumferential or ,peripheral ribs or beads l3 be provided on'the outside of the body portion I to further reinforce and strengthen the structure. Also, these ribs or bead portions i3; through the inherent elasticity or flexibility of the material, aid in cushioning and absorbing shocks sustained laterally by the body portion. a

At one side, the portions i and 2 of the jug formation have a recess l4 formed to extend vertically substantially from the bottom to the top of the jug portion. The formation of this recess to extend up adjacent to the height of the bottom of the filler portion 5 requires the embodiment of an extension or boss l5 upon the portion 2 of the jug or body, and a bore is formed through this bossed or enlarged portion I! to receive the glass gauge tube l8, which is thus disposed to lie and be protected entirely within the recess I4. A p rt I! establishes connection with the lower end of the gauge tube l6, and a screw portion I8 turned into a correspondingly threaded portion of the bore I5 and holding the gauge tube in place has an air escape port I! therein communicating with the interior of the jug portion. Suitable packing washers 20v are provided to form liquid tight connections and to cushion the ends of the glass gauge tube IS.

A connecting nipple 2| is secured in the laterally opening passage 8 to be substantially within the reentrant recess 9, and the outer rim marginal portions of this recess 9 are rounded over or rolled in form, as at 22. A battery filler hose 23 is fitted at one end on the connecting nipple 2|, and this battery filler hose, which is preferably of soft rubber, may have a filler tip 24, of hard rubber, vulcanite, or other suitable material, at its outer end.

A supporting ear 25 is provided on the upper part of the jug portion, preferably above the placement of the connecting nipple 2i, and this supporting ear 25 has an opening 26 therethrough of suflicient size to receive and hold the free end of the battery filler hose 23, substantially after the manner illustrated in Figure 1.

As has been stated, the body or jug portion will be substantially opaque, or at least suiiiciently lacking in transparency to permit the user to determine with any degree of accuracy the amount of liquid contained therein and consequently the glass gauge tube is'provided to definitely, readily and accurately show the amount of liquid. Due to the fact that this tube is entirely within the recess i4 and is thus shaded, it may be necessary to provide a back card, shield, or reflector 21 within the inner side of the recess I back of the gauge tube I 6 to permit a better view and more definite and accurate determination of the water height.

In constructing the body or jug portion, the wide opening at-the upper end of the tapered portioii 2 will allow ready access for molding, removing mold sections, and the like, and when the mouth or filler portion 5 is mounted in place this restricts the opening sufiiciently to give a convenient filler opening and to yet give a conven-. ient and efiicient support for the bulb portion of a syringe hydrometer. In the construction of the body or jug portion, the filler portion 5 is made of rubber,'or other material that can be treated to be hardened, or of any suitable material that will stand the heat required for vulcanizing or hardening the material of which the portions I and 2 are constructed. The body or jug part, consisting of the portions i and 2, is then molded or shaped, and while yet in a pliable state is fitted over the flanged end of the filler portion 5. The entire structure is then subjected to further vulcanization or other curing, and the material then becomes firm and of more or less rigid character, at the same time being sumciently elastic and yieldable to resist breakage and to cushion against and absorb shocks encountered in use.

With the filler portion 5 constructed to be of substantially tubular truncated cone shape, the bulb of a syringe hydrometer will be conveniently and sufliciently supported thereby, as illustrated in Fig. 3, and yet if the hydrometer be twisted or moved to dispose its long axis diagonally, when being inserted in the jug or removed therefrom, the tapered flared formation of the part 5 will guard against contact with the glass barrel or other frangible portion of the syringe hydrometer to avoid breakage of or damage to the same. Further, this widened flared form lends to more ready placement and removal of the hydrometer.

Due to the fact that the glass gauge tube II is entirely within the recess l4, this tube is substantially housed and protected against contact with surfaces or objects that might cause breakage of the tube, and at the same time the tube is protected against contact with greasy or dirty objects that would cause smudging of the glass and obscuring of a proper and expeditious reading of the liquid height.

As the reentrant recess 9 has its outer edge rolled or rounded over as at 22, no sharp edge or corner is presented against the battery filler hose 23, and in consequence the hose will not be chafed, cut, or otherwise injured in use; nor, will the hose break or kink against the contacting portion of the jug structure.

My improved battery filler can be readily .23 is presented in convenient position for insertion within the filler opening of a battery or cell. The filler hose 23, being of soft rubber, can be pinched between the thumb and fingers to prevent the passage of water therethrough and the end of the hose can then be inserted in the battery filling opening without danger of leakage or spilling water upon the top of the battery. When the proper amount of water has been filled into the battery cell, the hose is again pinched to cut off the flow, and when the hose end has been raised above the liquid level and inserted through the opening 26, there is no possibility of water being spilled through or leaking from the filler hose.

While I have herein referred to this invention as a battery filler, and have described its construction and use only for this purpose and for dispensing distilled water, it will be appreciated that this invention can be used for substantially any and all liquids and to dispense such liquids wherever desired. Further, it will be appreciated that changes and variations can be made in the form, construction, arrangement and assembly of the parts without departing from the spirit and scope of my invention.
