DE LANCEY, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNORS T GILBERT BARKER MANUFACTURING COMPANY, 0F WEST SPRING? FIELD, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS LIQUID DISPENSING APPARATUS Application led November 15, 1929. Serial No. 407,532.

This invention relates to improvements in liquid dispensing apparatus, of a type adapted for dispensing gasoline, oils and the like. The invention has for one object the provision. of improved means for locking up the 'nozzle of the dispensing hose, when not in use, preferably in a manner such that it not only cannot be used but also so that it is protected from the weather.

The invention also has for an object the provision of hose nozzle locking means of a type which will 'also prevent opening of the valve of the nozzle while the latter is locked M Another object of the invention relates .to

a liquid dispensing apparatus, having a power-operated pumping means with means for starting and stopping the same, and -consists in an arrangement, whereby the hose 2o nozzle when in position for locking prevents operation of said starting and stopping means.

A further object of the invention relates to a liquid dispensing apparatus having` a plurality of delivery hoses, all served from a single power-operated pumping means, and 4consists in an arrangement, whereby the How to any one hose must be stopped before the nozzle of that hose can be placed in position for locking and whereby the pumping means must be stopped before all the hose nozzles can be placed in position for locking.

I have chosen as an illustrative embodiment of my invention, a so-called meter-type 85 dispenser, including an electrically or other power driven pump which supplies two discharge lines, each including a meter. The invention, however, is capable of use in many other dispensers, which diffenwidely from that herein shown, and itris therefore not the intention to have the invention restricted to the particular form of dispenser shown.

Other objects and advantages will appear in the following description and will be pointed out in the appended claims.

The invention will be disclosed with reference to the Vaccompanying drawings, in which Figs. 1 and 2 are front and side elevational views, respectively, of a dispensing apparavided with outwardly projecting parts 16 tus embodying our invention,-the enclosing casing of the apparatus bein shown in section and certain parts being' roken away to reveal interior mechanism;

Fig. 3 is al sectional plan view taken on the line 3-3 of Fig. 1;

Figs.`4 and are fragmentary views, taken from the same direction as Fig. 2 but drawn to a larger scale to clearly show the detail of the valve and switch operating mechanism; and

Fig. 6 is a sectional view taken o n the line 6-6 of Fig. 5.

The apparatus includes a framework (Figs. 1 and 2) made up of a base 10, a cap 11 and four upstanding pipe columns 12, which are secured at their lower ends to the base and at their upper ends to the cap. The space between the base and cap. is enclosed by a two-part sheet-metal casing 13 of modified square cross section. The cap 11 is formed with lateral openings 14 '(Fig. 2) in the front and back, through which electric lamps 15 may extend. The cap is-also pro- 'u' which form hoods for the lamps. The cap may also support'the usual ornamental illuminated globe, indicated in part at 17 The several lamps are mounted in sockets, such as 18, and these in turn are supported by conduits 19, camying the supply wires 20.

In the lower portion of the apparatus is a su; table pump 21. having a rotary drive shaft 22, suitably coupled, as by a exible coupling 23 to the drive shaft 24 of an electric motor 25. The motor and pump are suitably secured to the upper and lower ends, respectively, of a frame 26. This frame lies between and is bolted to a pair of angle irons 27.. Each angle iron is secured to the adjacent pipe column 12 by U-bolts 28. A conduit 29 leads, from a position near the base 10, upwardly to a condulet 30 which is suita# bly secured to the frame or motor 25 and carries a branch conduit 31 leadin to a. switch housing 32. The switch, contained in housing 32, has a lever 33 which normally occupies the position shown in Fig. 2 and tends to assume that position wherein the switch is open. This switch controls motor 10 and 31.

The suction side of pump 21 is connected to a pipe 33', adapted for connection to an underground supply tank. To the dis-` chargle sideof the pump, a'pipe 34 is connected yw ich supplies two branch pipes 35, each leading to a suitable ow .meter 36. Connected to pipe 34 is an air dome 37. Interposed in each branch pipe 35 is a suitable stop valve 38, having an operating shaft 39, carrying a lever 40. The flow meters 36 have 4dials 41 and indicators 42 (Fig. 1) which are visible through suitable openin s 41 in casing 13, as will be clear from ig. 2. The discharge pipe 43 for each meter leads horizontally outward, thence upwardto cap 11 and thence outward through a suitable opening in the cap. To the end of pipe 43 is attached a suitable sight glass 44 and to the latter the usual dispensing hose, shown in part at 45. The free end of each hose carries a valved hose nozzle 46, having an operating lever 47 and a guard 48 for the latter.

Thettwo meters are supported by and between a pair of plates 49. The inner and adjacent corners of these plates are cut olf at an angle, as at 50 (Fig. 3). ThisA allows the body of meter 36 to enter between the pair' of plates far enough so that two of the studs 51, which secure the sections of the meter housing, can be passed through holes in the plates and secured thereto by nuts 52. The outer and non-adjacent edges of plates 49 have upstanding flanges 53, each of which abuts a pipe column 12 and is clamped thereto by a U-bolt 54.

Intermediate the two flanges 53 of each plate is a centrally located and forwardly extending part 55, which terminates with a.

downwardly turned flange 56. Secured to.-

each such flange is a bracket 57, Ywhich extends outwardly through casing 13 and, near its outer end, carries an upwardly extending lug 58 having a hole 59 therethrough. The hose nozzles 46 are adapted to be supported one on each bracket 57. Part of the: guard 48-of each hose nozzle can rest on bracket 57 rasshown in.-Fig. 1 while-the remainder of upper end must be lnserted in a hole 60 in casing 13.

v Levers 61, one forL each meter of the apparatus, are provided for operating, from a point outside the casing, the motorswitch and the two valves 38. Each such lever is fixed to the outer end of a shaft 62. The two The alined shafts 62 are rotatably supported by two bearing bushings 64, secured one in each flange 56- and below the bracket 57. Each bushing passes through flange 56 and has a flange 65 (Fig. 6) to abut the outer face thereof. The inner end of each bushing is threaded to receive a nut 66 by which the bushing is clamped to flange 56. Each shaft l is held against undue endwise movement between the hub of its lever 61 and a collar 67 fixed to the shaft.

Each shaft 62 has xed thereto a lever 6 8 and both these levers are located inside housing 13. Each lever 68 carries two heads 69 and 70, arranged one on each side of the lever and at radially spaced points. Each of these heads is mounted to turn freely in'the lever about an axis parallel tothat about which the lever turns. A link 71, in the form of a round rod, is threaded at one end into each `head 69, or otherwise adjustably connected thereto, and at its other end is slidably eng ged with a head 72, having a vertical trunn: on 73 which loosely fits in a hole in a valve lever 40, being held in place by a pin 74. An abutment 75 is formed on each link 71 toengage one face of its head 7 2 and the opposite face thereof is engaged by a spring 76 coiled around the link and held in place by a washer 77 and cotter pin 78. The other head 70 in each lever 68 is connected by a link 79 to the switch operating lever 33. Link 79 is threaded in head 7 0, or otherwise adjustably connected thereto, and near its other end has shoulders 80.. The connection of both links 79 to lever 33 is effected bymeans of substantially U-shapedpieces 81, arranged one on each side of lever 33 'with the cross bar portion of each engaging the lever and pivotally connected thereto by a pin 82. The links`7 9 are slidably engaged, one in each of the members 81,' sliding in the outstanding ears thereof, until arrested by the engagement of the shoulders 80 with the uppermost ears. i

With the parts positioned as in Fig. 4,*both valves 38 are closed and the motor switch is open. With both hose nozzles hung up on their respective supports, the guards 58 of the hose nozzles will prevent movement of levers 61 in such directions as would cause opening of their respectiye valves or closing of the motor switch. Movement of either lever 61 in the opposite direction is permitted to a limited extent by the springs76 but not to any such degree as would enable the links 79 to be drawn out'A of the ears of members 81. With either hose nozzle removed from its support, one of the levers 61 is then free to move into a position such as shown in Fig. 5, and when so moved causes the openingof the valve 38, controlling the pipe which supplies the nozzle thus removed. Also the switch lever 33 is moved to on position. In opening the valve 38, the shoulders 75 engage head 72 and thus move lever 40. In closing this valve the transmission from link 71 to head 72 is through spring 76 and, after the valve has been closed, this spring yields, if necessary, to allow lever. 61 to be brought back far enough to permit the'hose nozzle to be hung up on its support. It is usually desirable to have the movement of link 71 somewhat in excess of that required to close thevalve to insurea tight closure of the Samef/-the spring 76 taking care of any overtravel of the link. In closing the motor switch the shoulders 80 on the particular link 79, which is moved downwardly, engages its member 8l and moves the same. When this link is drawn upwardly by the movement of lever 61 into valve closing position, the link 7 9 willslide till) in member 81, but the switch lever will be restored to the position-shown in Fig. 4, by the mechanism of the switch which is of the self opening type. To hold the switch closed, the pivot 70 between lever 68 and link 79 is arranged to cross slightly to the left (as viewed in Fig. 5) of the line connecting the centers of shaft 62 and pivot 82. The valve lever 40 can move only through a limited arc and, when the valve is opened as shown in connection with the left valve in Fig. 5, its lever limits the extent to which the pivot 70 can cross the aforesaid line of centers.

In operation, one or the other of the hose nozzles must be removed before the operator can start the pump motor or open either of the valves 38. Having removed a hose nozzle, the operator moves lever 61 into a position, such as shown in Fig. 5, and far enough so that the lever will remain in its moved position due to the crossing centers action, above described. By so doing, the pump 21 is set in operation and that valve 38, which controls the flow to the nozzle thus removed from its support, is opened. rlhe operator then inserts the nozzle in the lling opening of a. gas tank and controls the flow 'by means of the lever i7 of the nozzle valve. l/V hen the liquid delivery operation has been completed the operator naturally wishes to hang up the nozzle and the only means provided for this purpose is the bracket 57. Before the operator can hang up the nozzle on this bracket, he must move lever 6l out of interfering relation with the bracket and by so doing, he causes the valve 38 to close and, if the other nozzle is also hung up, stops the pump naotor.` The stopping of the motor, however, cannot take place until both nozzles are hung up. rIhat is, while each valve is independently controlled by a lever 61, the control of the motor'by the levers, insofar as stopping it is concerned, is a joint action. Either lever can be moved to start themotor but both must' be moved to locking position lbefore the motor can be stopped. rIhe locking of the hose nozzle on its support also locks the hose nozzle valve lever 47 and the lever 61.
