UNITED STATES PATENT OFFICE nare n. BRADLEY, or DAYTON, OHIO, AssieNon To NATIONAL rms CORPORATION,

OF DAYTON, omo, A CORPORATION or omo LIQUID DISPENSIN G APPARATUS `.Application med'lApril 20,

This invention relates to liquid dispensing apparatus and more particularly to that type of apparatus commonly employed for dispensing gasoline, and is a continuation in part of the joint application o Hanna and Bradley, filed September 5, 1930, Serial N o. 479,870.

One object of the invention is to provide such an apparatus with a hose support adapted to have interlocking connection with then hose nozzle of such a character that the nozzle can be quickly placed on and removed from the support and will be firmly supported thereby.

A further object of the invention is to provide such a hose support with means for preventing the opening of the nozzle valve while the nozzle is mounted on the support.

A further object of the invention is to provide such a support with improved means for controlling the discharge of liquid from the apparatus.

Other objects of the invention will appear as the apparatus is described in detail.l

In the accompanying drawing Fig. 1 is. a side elevation of a portion of a liquid dispensing apparatus showing my invention applied thereto; Fig. 2 is a rear elevation of the switch and valve controlling mechanism; and Fig. 3 is a section taken through the support on the line 3-3 of Fig 1.

In the drawing I have illustrated one einbodiment of my invention and have shown the same as applied to a dispensing apparatus of that type commonly known as a meter pump. This apparatus comprises a. discharge pipe 5 adapted to communicate with an underground tank and having interposed therein a rotary pump 6 which is operated by an electric motor 7, the motor being controlled bv a switch 8. A meter 9 is interposed in the discharge pipe beyond the pump, and connected with the outer end of the discharge ipe is a flexible hose 10, the pipe and the liose constitutin the discharge conduit for the apparatus. t(linterposed in the discharge pipe, between the meter and the flexible hose, is a cut-off valve 11.

rIhe hose 10 has at its dischar e end a nozzle 12 provided with a valve 13. ivotally 193i. sei-iai in. 531,461.

mounted on the nozzle is a lever 14 for actuating the valve and this lever is rotected by a guard 15 rigidly secured to t e nozzle and extending about the lever. The guard is provided with a slot 16 and the valve actuating lever has a slot 17 arranged in line with the slot in the guard. Mounted on a fixed part of the apparatus, in the present instance on the discharge pipe, is a hose supporting arm 18, here shown as a fiat bar which projects laterally beyond the apparatus and is adapted to be inserted through the slots in the nozzle guard and lever to support the nozzle and hose when the latter are not in use. The arrangement is such that the nozzle may be quickly and easily placed upon the support ing arin or removed therefrom and when mounted thereon will be firmly supported and held against turning movement. The guard arm is of such a length that when the nozzle is supported thereon the outer end of the arm will lie close to the body of the nozzle and the outer portion of the arm has therein an opening 19 so arranged that it will be located on the outer side of the valve actuating lever when the nozzle is properly positioned on the supporting arm. This opening is adapted to receive a looking device, such as a padlock 20, which serves both to retain the nozzle upon the supporting arm and to prevent the operation of the valve actuating lever while the nozzle is supported on the arm.

The supporting arm may also have near its outer end a recess 25 to receive a part carried by the nozzle, such as the hook 26, and thus provide means for quickly engaging the nozzle with the supporting arm between delivery operations and when it is not desired to lock the apparatus.

If desired, the su porting arm may be provided with means or controlling the switch 8 and the cut-off valve 11 and, as here shown, a crank arm 21 is rigidly connected with the supporting arm for movement therewith and is connected by means of a link 22 with the switch 8 4and by meansofa link 23 with the cut-oil' valve 11. The arrangement is such that when the supporting arm is in a position to sup ort the nozzle the switch will be open and t e valve 11 closed. Ifdesired, a

spring may be provided to raise the arm and thus close the switch and open the valve when the nozzle is removed from the arm. In the present arrangement the spring is applied to the link 22, as shown at 24. The weight of the nozzle and hose on the supporting arm will retain the switchfopen and valve closed so long as the nozzle is supported on the arm.

When the nozzle is removed for use the supporting arm is moved upwardly into the position shown in dotted lines, either manually or by the spring, thus causing the crank arm 21 to close the switch and to open the valve 11.

While I have shown and described one embodiment ofmy invention I wish it to be understoodthat I do not desire to be limited to the details thereof as various modifications mayT occur to a person skilled in the art.

aving now fully described my invention, what I claim asnew and desire to secure by Letters Patent, is:

1. In a li uid dispensing apparatus, a discharge conduit including a flexible hose, a nozzle on the delivery end of said hose having a valve, a lever for operating the valve, a guardA for said lever secured to the nozzle, said lever and said guard having alined openings, and a support for said nozzle adapted to extend through the openings in said guard and said lever and to have supporting engagement therewith.

2. In a liquiddis ensing apparatus, a discharge conduit inc udinga flexible hose, 4a nozzle on the delivery end of said hose having a valve, a lever for operating the valve, a guard for said lever secured to the nozzle, said lever and said guard having alined openings, and a supporting arm adapted to extend through the openings in said guard and said lever and having an opening to receive a locking member to hold said lever against movement whiler said nozzle is supported on said arm.

3. In a li uid dispensing apparatus, a discharge con uit including a flexible hose, a nozzle on the delivery end of said hose having a valve a lever for operating the valve, a guard or said lever secured to the nozzle, said lever and said guard having alined openings, and a support for said nozzle adapted to extend through the openings in said guard and said lever and to have supporting eiigagement therewith, said support having a recessed portion with which a part carried by said nozzle may be engaged to support said nozzle thereon independently of the opening in said guard.

4. In a liquid dispensing apparatus, delivery mechanism including a controlling device, a housing enclosing said delivery mechanism and having a slot therein, a discharge conduit leading from said delivery mechanism to the exterior of said housing and including a flexible hose, a nozzle on the delivthe end of said nozzle when the latter is placed on said supporting member, said opening being arranged to prevent the vertical movement of said nozzle while said lever and said guard are in supporting engagement with said supporting member.

In testimony whereof, I affix my signature hereto.

ERIC H. BRADLEY.
