CORPORATION, OF DAYTON, OHIO, A CORPORATION OF OHIO LIQUID msrnnsm'e grammes Application flled OctoberJ, l98. S'erial No. 309,461.

This invention relates to liquid dispensing apparatus and more particularlyl to a gasoline pump of that type in whic a delivery receptacle is drained through the delivery 6 hose to a drain pipe, which usually leads back to the storage reservoir. To drain the delivery receptacle in this manner the drain pipe is provided with a receptor or socket into which the nozzle of the hose is inserted and in which it is retained during the draining of the receptacle.

One object of the invention is to provide a simple easily operated means for retaining the nozzle in the receptor and for sealing the connection between the same.

A further object of the invention is to provide such retaining means which will hold the valve in the hose line open so long as the nozzle is retained Within the receptor.

A further object of the invention is to provide a simple eflicient locking device to positively prevent the separation of the retaining devices and to thus prevent the removal of the nozzle from the receptor.

A further object of the invention is to provide means controlled by the presence of the nozzle in the receptor to prevent the closing of a valve in the hose line; and to prevent the insertion of the nozzle in the recepto when that valve isclosed.

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

In theaccompanying drawings Fig. 1 is a vertical sectional View, partly in elevation and partly broken away, of a gasoline pump embodying my invention; Fig. 2 is a side elevation of the nozzleand a portion of the receptor; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2; Fig. 4 is a transverse sectional view taken approximately on the line H of Fig. 2: Fig. 5 is a side elevation of the receptor and controlling device show ing the cap' for the receptor in its closed position; and Fig. 6 is a detail view of a portion of the nozzle. I

In these drawings I have illustrated one embodiment of my invention and have shown the same in connection with a gasoline dispensing pump of a well known type. It will be understood, however, that this particular embodiment has been chosen for the purposes of illustration only and that the mechanism may take various forms and may be applied to dispensing apparatus of various kinds without departing from the spirit of the invention. j

The dispensing apparatus shown in the drawings comprises a hollow standard or housing 1 on the upper'end of which is supported a delivery receptacle 2, preferably havingtransparent walls. Connected with the. bottom of this delivery receptacle is a delivery hose 3 having at its free-end a dischargenozzle 4.. The deliveryreceptacle is provided with an overflow pipe 5 which is connected with a 'drain pipe .6, preferably leading back to a storage reservoir, and which serves to return to the storage reservoir any 01' DAYTON, OHIO, ASSIGNOR TO THE NATIONAL PUD IFS excess liquid pumped into the delivery recep- I tacle.- The pumping mechanism for filling the delivery receptacle is not shown but. may be of the usual or any suitable .type Conlnected with the drain pipe 6 andarranged on the outside of the housing 1 is .arecept orpr socket member 7 adapted to-receive the Inez; zle l. Suitable means are provided for seal:- ing the connection between the sockefiaiid the nozzle and, as here shown, the nozzle is pro.-

vided with a flange 8 in which is'arranged a gasket 9 to engage the upper edge of the re.- ceptor, so that when the nozzle depressed firmly into the receptor the gasket willseal the connection. The discharge-portion of the nozzle is preferably of flexible material,

such as interlocking flexible brass tubing,

thus adapting the nozzle for insertion in the straight socket of the receptor but.perinit.- ting it to be bent or shaped by hand to adapt it to insertion in the filling fuel tanks of different automobiles.

The nozzle and receptor are provided with cooperating parts to retain the nozzle; in the receptor and these parts are preferably of such a character that when brought into cooperating relation they will press the gasket 9 firmly against the end of the-receptor. These cooperating parts are, in thef present instance, of such a character. that they may be brought into interlocking relation. by. the

movement of the nozzle in the receptor. The

opening of the nozzle 4 has a laterally extending lug constituting a retaining 'member and, in the present instance, thislug is connected at its outer end with, and forms a part of the structure of, a handle 11 by means of whichthe nozzle is manipulated. The receptor 7 has near its upper end a. laterally extending part 12 which is preferably provided at its outer end with a flange 13 on which the outer portion of the retaining member 10 of the nozzle rests and on WhlCh it may have sliding movement. Rigidl y secured to and, in the present instance, forming a part of the laterally extending member 12, is a lug 14 extendlng transversely to the retaining member 10 of the nozzle and constituting a second retaining member to cooperate with the retainin member on the nozzle. This second retaining member 14 is spaced above the flange 13 a distance suificient to permit the lug or retaining member 10 to enter the space between the flange and the lug 14 when the nozzle is moved about a vertical axis in the receptor, thereby causing the lug 10 to engage the underside of the lug 14 and to be so interlocked therewith as to retain the nozzle in the receptor. Preferably one or both of the retaining members have their contacting surfaces inclined, as shown at 15, so that when they are brought into interlocking engagement the nozzle will be pressed down wardly to insure a tight sealing contact between the receptor and the gasket 9.

The gasoline pump to which the invention is here applied is of the wet hose type, that is, the hose is normally full of gasoline. To this end the nozzle 4 is provided with a valve 16 to control the flow of gasoline through the hose. This valve is not shown in detail but may be of any suitable character in which the valve member is normally closed, as by a spring. A valve stem 17 projects beyond the nozzle and is arranged to be engaged by one arm, 18, of a bell crank lever which, in the present instance, is pivoted on the handle structure 11, and the other arm, 19, of which is arranged adjacent to the handle to be enaged by the fingers of the operator, wherey the movement of the lever will actuate the valve stem 17 to open the valve in the nozzle.

- The retaining member 14 of the receptor is so arranged that the valve will necessarily be open when the two retaining members are brought into interlocking relation and, as here shown, this retaining member is arranged in the path of the arm 18 of the actuating lever so that that lever must be moved to a position to open the valve before the retaining members can be fully interlocked. Preferably the outer end of the retaining member 14 is beveled, as shown at 20, so that it will engage the end of the arm 18 of the actuating lever and automatically open the valve when rotatory movement'is imparted to the nozzle to move the retaining member 10 into interlocking engagement with the retaining member 14. The valve will be retained in its open position as long as the retaining members are interlocked.

A locking device is provided to positively prevent the withdrawal of the nozzle from the receptor, this locking device being preferably key controlled. In the present construction, the locking device comprises a lever 21 mounted on a fixed part of the apparatus adjacent to the receptor, such as a bracket 22 secured to the housing 1, and movable into the path of the retaining member 10 of the nozzle when the latter is in operative engagement with the retaining member 14 of the rereceptor, thereby providin a positive stop to prevent the rotation of t e nozzle in a direction to separate the retaining members. As here shown, the locking member 21 is slotted at 23 to receive a pivot lug 24 on the bracket 22 and therefore has both pivotal and sliding movement with relation to the bracket. When the nozzle is to be locked the looking member is moved into a horizontal position and then slid lengthwise into the path of the retaining member 10. The locking member here illustrated has a laterally extending flange 25, the outer edge of which is inclined to engage the retaining member 10. This flange has an aperture 26 so arranged that when the locking member is in its operative position the aperture will be in line with a second aperture 27 which, in the present instance, is formed in a lug 28 carried by the bracket 22, the a-l ined apertures being adapted to receive the hasp of a padlock 29.

In the present apparatus the hose line is provided with a second valve 30 which, as

here shown, is interposed between the end of the flexible hose and the delivery receptacle. This valve is actuated by a shaft 31 which is operatively connected therewith and is provided with an actuating handle 32. In a wet hose pump this upper valve 30 is normally open and is in fact an emergency valve. In a dry hose pump, that is, one in which the hose is normally empty, the valve 30 may constitute the controlling valve for the hose. As has been stated, in the wet hose pump the valve 30 is normally open and is usually sealed in its open position. The operation of the valve 30 is controlled by a device of such a character and so arranged as to make it necessary that the valve shall be opened before the nozzle can be inserted in the receptor and to prevent the closing of the valve 30 while the nozzle is in the receptor. As here shown, this controlling device comprises a lever 33 pivotally mounted on the receptor and connected by a rod 34 with an arm 35 on the valve actuating shaft 31. the connection being of such a character that the lever 33 will be moved about its axis when the valve is opened or closed. A cap or closure 36 is pivotally mounted on the receptor and arranged for movement into and out of a osireceptor, and when the nozzle is in the receptor the cap will be held in its open position by contact therewith. The lever 33 has a proj ecting end or finger 37 so arranged that when the valve 30 is open this finger will be out of line with the mouthof the receptor, thus permitting the nozzle to be inserted therein or the cap to be moved to its closed position. If the valve 30 is closed when the cap 36 is in its closed position the finger 37 will be moved into a position immediately above the cap and will thus prevent the opening of the receptor until the valve 30 is opened. Should the valve 30 be closed while the cap 36 is in its open position the finger will extend across the open mouth of the receptor in such a manner as to prevent the insertion of the nozzle. Therefore the valve 30 must be opened before the nozzle can be inserted in the receptor. When the nozzle is in the receptor any attempt to close the valve 30 will cause the finger 37 of the lever to engage the nozzle and prevent the further movement thereof and thus prevent the valve from being closed.
