LIQUID-DISPENSING NOZZLE. i

Application filed October 22, 1920. Serial No. 418,789;

of the liquid is greater than the vclosing presl sure on the valve.

My invention is particularly directed to an improvement inthe dispensing nozzle located at the free end orp the flexible hose which leads from a gasoline pump, whereby the gasoline which is left in the flexible hose will be retained therein so that each purchaser of gasoline will receive exactly the amount of gasoline registered by the pump, the valve at the same time serv-l ing to prevent leakage at the nozzle, and being so arranged that it cannot be tampered with at the exterior.

A practical embodiment of my invention is represented in the accompanying drawing, in which,

Fig. l represents the liquid dispensing nozzle in top plan.

Fig. 2 represents the same in side eleva-- tion.

Fig. 3 represents a section talren in the plane of the line lll-lll of Fig. l.

rllhe flexible hose which leads to the gasoline pump, not shown herein, is denoted by l. lt may be provided with a nipple 2 by means of which it may be secured to the branch 3 of the dispensing nozzle by means of a suitable union l.

The dispensing nozzle is provided. with a partition 5 upon one side ot the lateral supply port 16, which partition forms the bottom of a recess 6. A suitable cap 7 serves to close the mouth of the recess 6. The noz-v zle is provided with a partition 8, upon the other side or' the lateral supply port 16, which partition has a discharge port 9 therethrough.

At the discharge end of the nozzle, a strainer l() may be located, which strainer is held in position by a union 11, which engages the nozzle and also the iiange of a nozzle extension l2.

T he head i3 oit' the discharge valve serves to open and close the discharge port 9. The valve stem 14 extends through the partition 5, into the recess 6 where ay spring l5 engages the stem for normally holding the discharge valve closed. It is intended that this spring shall be suiiiciently powerful to hold the valve closed against the weight oi the liquid inthe line back of the valve except when the delivery pressure is exerted on the liquid as for instance, by the operation of the pump. greater than the pressure of the spring l5, therebyl automatically opening the valve. The moment the delivery pressure stops, the valve will automatically close, thus holding the liquid in the line back of the valve so that on the next operation of the pump, the discharge of the liquid from the nozzle`i i mediately begins.

By the provision of this automatic discharge valve in the dispensing nozzle, an accurate measured supply of the liquid is ensured for each customer, thereby eliminating all discussion as to who is entitled to the liquid in the line beyond the pump, as so frequently happens in the type of liquid supply to which this invention is directed.

lt is evident that various changes may be made in the construction, form and arrangement of the several parts without departing 'from the spirit and scope of my invention; hence l do not intend to limit myself to the particular embodiment herein shown and described, but,

lWhat l claim is l. it. liquid 'dispensing nozzle having a lateral supply port, a partition forming a recess on one side of the supply port, a par tition having a discharge port therethrough on the other side of the supply port, a valve for the dischargel port having its stem extending into said recess, and a spring in said recess engaging said stem to normally hold the valve closed.

rlhis delivery pressure will be 2. A liquid dispensing nozzle having a enga-ging said stem to normally hold the lateral supply port, a partition forming :L valve closed, and a. cap foi' closing the mouth recess on one side of the supply port, :i parof said recess. "i0 tition having a discharge port therethrough n testimony, that l claim the foregoing as 5 on the other side of supply port, a valve for my invention, l have signed my name, this the diseharge port having its stem exteiid- 18th 'clay of October, 1920, ing into said recess, a spring in said recess EMERY REED.
