Dec. 2, 1952 cs. D. SPENCER NOZZLE FOR BOTTLES Filed Feb. 14, 1950 Patented Dec. 2, 1952 NOZZLE FDR BOTTLES George Douglas Spencer, Erdington,

Birmingham,

England, assignor to Joseph Lucas Limited, Birmingham, England Application February 14 In Great Britai For use in replenishing (or topping-up) the electrolyte in an electricity storagebattery, it is known to employ a Water bottle having a nozzle which can be inserted through a hole in the battery case. The nozzle is of the kind which contains a spring-loaded valve having a stem which projects from the nozzle and when pressed into contact with the upper edge of one of the battery plates, causes the valve to open. Water can then flow from the bottle to the battery until the end of the nozzle is sealed by the liquid in the battery. Further discharge from the bottle then ceases.

The primary object of the present invention is to provide an improved nozzle for use on a bottle as above described. The invention may, however, be applied to bottle nozzles for other analogous purposes.

In the accompanying drawings:

Figure 1 is a sectional side elevation and Figure 2 an end elevation illustrating an embodiment of the invention.

Figure 3 is a cross section on the line 33 Figure 1.

Referring to the drawings, the nozzle comprises a tube a of appropriate length and diameter, and having at one end a socket b adapted to eifect a screw-thread or equivalent connection with the bottle neck 0. At the junction of the tube and socket is formed an annular seating d for a valve 8 of the poppet type, and from the valve extends a stem 1 which projects slightly from the outer end of the tube a. Longitudinal ribs 9 on the stem serve to centralise the valve stem in the tube.

According to the invention, there is employed a washer made from rubber or other convenient flexible and resilient material. The washer is shaped to provide an outer annular part It adapted to be supported on a shouldered portion of the socket, a central boss 1' extending from one side of the washer and adapted to bear on the valve, and a plurality of radial arms 9 interconnecting the boss and annular part, the arms providing between them adequate apertures for the free flow of water therethrough. Preferably the boss 2 is formed with an axial bore as shown to receive a short central projection is on the valve.

When the nozzle is attached to the bottle neck,

11 March 10, 1949 1 Claim. (Cl. 226-19) the annular part of the washer serves to effect a fluid-tight seal between the nozzle and bottle, and the boss serves to hold the valve on its seatmg.

The mode of use of the bottle for topping-up a battery is the same as that above described. On pressing the projecting end of the valve stem into contact with the upper edge of a battery plate the valve is moved off its seating, at the same time causing the arms of the washer to be elastically deflected. On withdrawing the nozzle the arms resume their initial position and cause the valve to be re-closed.

By this invention a desirable and advantageous simplification is effected in the construction of bottle nozzles of the kind described.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

A bottle nozzle comprising the combination of a tube having at one end a socket for attachment to the neck of a bottle, the socket having a shouldered portion, an annular valve-seating between the socket and tube, a valve co-operating with the seating and having a stem which extends through and slightly beyond the outer end of the tube, and an apertured washer made from flexible and resilient material and seated on the shouldered portion of the socket to effect a fluidtight seal between the socket and the outer end of the bottle neck when the socket is attached to the bottle neck, the washer being formed with a central boss which serves to press the valve on to its seating.

GEORGE DOUGLAS SPENCER.
