To Il whom it may concern:

Be. it known that we, WILLIAM ERNEST Kansnaw, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia` and 4State of Pennsylvania,

and CARROLL Hoven, a citizen ofthe United States, residingv at Radnor, in the county of Delaware and State of Pennsylvania, have jointly invented a new anduseful Improve- 1nent in Battery-Cell Fillers, of which the followingvis a specification.

The principal object of the present invenltion is to provide a cell filler adapted for attachment'to a hose or tube and in which the signal and its battery and circuit connections and all the other parts are portable as a unit at the end of the hose or tube through which the supply of fluid is delivered. Another object is to facilitate the 2 operation of` filling inconveniently located cells. f The third object of the invention is to provide for the use of a comparatively small battery .which does not add appreciably to the weight of the device; and another object of the invention is to provide a con venient, eliicient and simple cell tiller.

The invention will be claimed at the end hereof but will be first described in connection with the embodiment of it chosen from o other embodiments for the sake of illustration in the accompanying drawings forming part hereof and in which Figure 1 is a side view showing some'of the principal concealed parts in dotted lines.

Fig. 2 is a top or plan view of the righthand end of the device shown in Fig. 1 with parts omitted, and

Fig. 3 is a sectional view illustrating diagrammatically circuit connections.

VIn the drawings 1, generally, is a handle or stock, as of wood, internally chambered" as at 2 and forked or bifurcated at 4 is a signal lamp arranged through the wall of the stock or handle and visible from the outside thereof. As shown the lamp projects through a fiat 5 provided on the stock. y 6 is a battery arranged in the chamber 2 of the stock and it is removable through the end of the stock which is vnormally closed 5 by a detachable cap 7 having a contact spring 8 and constitaltingy one of the. ter` minals of the battery. The contact 9 oonstitutes the other terminal of the battery. The nozzle 10 is movably mounted in the u vbifurcation 3 and is provideduwith contacts yshown as made in two Aparts of which the Va head 17 to which the han le or stock is -pivoted and with an angle bend which re- 11 and 12 insulated from each other bv insulation 13 and adapted to be bridged bv liquid as will be hereinafter described. The contact 11 may well be of copper material andit is connected to the positive end of the battery as by a conductor 14. vThe contact l12 may well be of leaden material and it is connected to thc negative end of the battery as by a conductor 15. 'lhecontact- 11 is part 11al is detachable by means o a screw thread and this is advantageous because the part 11a is subject to wear and can be easily removed for renewal,- and when worn does not interfere with the operation of the device because the lead contact 12 controls the level at which the circuit is closcd'and the signal given. 16 is a collar mounted on and insulated from the other parts of the nozzle and it serves as a limit stop when the nozzle 1s inserted in the battery jar and it also serves to limit the range of movement of the nozzle in respect to the stock or nozzle. The contact 11 is hollow and is rovided with ceives the end of the hose or tube 18 which passes through a hole in the end of a centrally pivoted spring pressed finger released i lever 19 shown as carried by a band 20 on the stock orphan'dle. 11a may be provided with spaced feet or pro]ect1ons 21 to insure a fluid outlet even when the end of the nozzle is in contact with a flat surface and .with a screen 22 which prevents or opposes dripping and which is exposed to water.

'In use the nozzle is inserted into the filling opening of a battery jar a, and the collar 16 fixes the depth of the insertion. For this 9 operation. The lever 19 is pressed toward the stock or handle thus releasing the hose so that fluid runs through the hose and nozzle 10" Aand fills the battery. a. When this happens the circuit is closed through the electrolyte andthe lamp is lighted, indicating that the cell has been filled to the required level.

Thereuponthe handle 19 is released and the 105 filler lcan be conveniently used for filling other cells since it can be easily transported, because all of its parts, including the electric signal and its battery, are connected with and carried by it, A new battery can be pro- 110 The end of the nozzle vided by removing the cap 7. When the contacts are bridged by the electrolyte the oxygen given olf at the copper contact 11 by electrolytic action combines with the copper forming oxide of copper which is dissolved in the electrolyte. In this way the contacts oppose practically no counter electro-motive force to the voltage/of the battery 6, so that the latter may be comparatively small. Cop er and leaden materials are examples of electrodes which oppose little or no counter electro-motive force under the conditions presented in the operation of the described filler.

' It has been said that the part or tip 11 of the conductor nozzle 11, is removable or detachable from the conductor nozzle 11, and

for that purpose the conductor nozzle 11 terminates at ahigher level, or is shorter than the conducting contact 12 by which the normal level of the acid solution is limited, so that the joint or thread between the parts 11 and 11l is exposed to water flowing through the parts 1l and 11 and not to acid, and therefore the joint or thread between the parts 11 and 1la does not become corroded but can be easily detached.

We claim:

l. A portable cell filler comprising in combination a handle or stock internally chambered and bifurcated, a fluid supply tube arranged outside of said chambered portion of the stock, a signal lamp arranged through the wall of the stock and visible from the outside thereof, a battery arranged in the chamber, a nozzle movably mounted in the bifurcation and provided with contacts adapted for liquid bridging, a controlling valve for the nozzle, and circuit connections for the battery, signal and contacts.

2. In a cell iiller the combination of a stock or handle, a battery and signal mounted on the stock, a nozzle movable in respect to the stock or handle and provided with contacts, a fluid supply for the nozzle 1ncluding a valve carried by the stock, and circuit connections carried by the stock or handle, substantially as dcribed.

3. In a cell iller the combination of a handle or stock internally chamber-ed and carrying an electric signal, a -battery mounted in the chamber and carried by the stock, a fluid supply for the nozzle arranged outside of the chambered portion of the stock, and circuit connections for the bat-ter and signal including conta/cts adapted for liquid bridging.

4. In portable cell fillers the combination of a battery mounted-on the cell filler and contacts adapted for insertion in electrolyte and of which one is of copper and is connected with the positive end of the battery and of which the other is/of leaden material and is connected with the negative end of the battery, the leaden material and copper under electrolytic action being substantially devoid of counter electro-motive force whereby a comparatively small battery suitable for application to the stock can be employed.

5. In a portable cell filler the combination ofa battery and contacts connected therewith and adapted for insertion in electrolyte and being respectively of copper and leaden materials which do not develop counter electro-motive force. under electrolytic action whereby the battery can be small and portable.

6. In a portable cell filler the combination of a sleeve of insulating material, a leaden contact tube arranged outside of the insulating sleeve, a tube of conducting material arranged inside of the insulating sleeve, and a cont-act of copper material projecting beyond the insulating sleeve and having detachable connection with the conducting tube, substantially as described.

7. In a cell filler the combination of provisions including a Contact by which the high level of the electrolyte is indicated, a conductor nozzle through which water is supplied, and a joint inthe conductor nozzle located above the high level of t-he electrolyte and in the'path of the Water and by which the tip of the conductor nozzle can be readily removed.
