v UNITED STATES PATENT OFFICE GEORGE W. MACKENZIE, F BEAVER, PENNSYLVANIA, ASSIG-NOR TO CORRECT "MEASURE COMPANY, OF ROCHESTER PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA ELECTRIC METER- PUMP Application filed September ,Vide means for simultaneously controlling the main valve and the pump drive mechanism and which shall be" adapted to lock said mechanism in its inoperative position when the metering device is not-in use.
These and other objects will become more apparent from a consideration of the accompanying drawings in which like reference characters designate like parts and in which Fig. 1 is a front elevational view of a metering pump with the housings removed and embodying the principles of this invention; Fig. 2 is a side elevational view thereof; Fig.
- 3 is a detail view partly in section and partly in elevation illustrating the method of locking the nozzle and pump operating mechanism; F ig. 4 is a cross sectionalview of a' combination switch and valve for controlling the, drive mechanism and the valve; Fig. 5 is an end elevational view thereof; Figs. 6 and 7 are top plan and cross sectional views, respectively, of a by-pass valve employed in the system and Figs 8 is a cross-sectional view partly in elevation of a combined strainer and valve employed in the structure in the manner hereinafter described.
With reference to Figs. 1 to 3 inclusive, of the drawings, the structure therein illustrated comprises a base 1 an upper support- 2, vertical supporting rods 3.and an upper and lower housing 4 and 5 respectively.
Supported within the lower housing is a strainer 6 illustrated in Fig. 8 of the drawings havin the connection 7 leading to the storage tan from which the fluid is pumped and having a branch 8 connected to an upright pipe 9 and a by-pass connection at 10 which connects to the by-pass valve 11, which 80, 1929. Serial No. 396,116.
communicates with an expansion chamber 13. The connecting line 9 ofthe strainer is secured to the inlet connection 14 of a fluid pump 15 which is provided with a passage communicating at16 with the by-pass line 12 and a connection at 17 with a control valve generally designated at 18 and which is more clearly illustrated in Figs. 4 and 5 of the drawings.
The pump 15 is supported on a bracket 19 that is clamped to the uprights 3 and a motor 20 is secured to the underside of the support 19 and operatively connected by a. chain drive 21 with a sprocket wheel 22 that is mounted to rotate with the pump shaft 23. The control valve 18 is connected by pipe 24 to a meter 25 carrying an indicating dial 26 and the-meter is connected by pipe line 27 to a visible flow indicator 28 to which a flexible hose is connected at 29.
Mounted on the upper housing 4.is a dome 30 having a light bracket 31 secured. thereto provided with sockets32 for receiving an electric light bulb and asocket 33 is provided for lighting the face of the meter dial. The electric lights are controlled by a switch 84 provided with a switch box 35 which is connected by a conduit 36 to the upper lights and a conduit 37 to a conduit box 38, the latter being connected to another conduit box at 89 and thence to a source of electrical current.
As shownin Fig. 4-, a motor switch 40 is provided for controlling the drive motor 20, this switch being operated by a plunger 41 in response to the rotary movement of a cam 42 which latter is secured to a cam shaft 43 that is controlled in its angular movement by a lever 44' which is manipulated through an operating rod 45 shown in Figs. 2 and 3.
A second cam 46 is secured to the shaft 43 to operate the control valve 18, this valve being controlled with the operation of the motor switch 40 through the cam 42. The conlatter by an upright connecting pipe line 12 placed to permit drainage of fluid through the tube 49. The ball 47 seats on the flanged face of which constitutes a seat against which the valve 53 rests in its connected position and against which it'is biased by the coil spring 54. J
In Fig. 8 the strainer 6 is illustrated as provided with a valve 55 which is constructed to be seated against the pressure column of the valve and adapted to rise inresponse to fluid passing upwardly through the Valve passage.
The passage of valve 55 is cut oif from the main passage by a filter screen 56 through which the fluid must pass when it is drawn from the source or storage tank by the pump 15.
As shown in Fig. 3 of the drawings, a nozzle 57 is secured by a flexible hose 58 leading to the connection 29 of the flow indicator and the nozzle is adapted to rest in a hood '59 provided on top of the pump when not in use. In this position, the nozzle bracket 60 and the operating lever 61 are adapted to pass over a hook 62 which is provided with a perforation or opening 63 for receiving a pad lock whereby the nozzle may be locked in its inoperative position. To place the nozzle mechanism on the hook 62 it is necessary to depress the latter to its lowermost position, thereby depressing the operating rod 45 to the position where the cam shaft 43 is rotated to shut off the motor switch 40 and the main valve 18.
The operation of the meter pump is briefly as follows :lVith the nozzle 57 removed from hook 62 the latter is lifted to rotate cam shaft 43 by raising the operating rod 45 and turning the crank or lever 44 that is secured to the cam shaft 43. When so raised, switch 40 is operated to energize the pump motor 20 and simultaneously the'valve 18 is depressed by its cam 46 to the open position. WVhen the pump is actuated the fluid is drawn through the strainer 6, the valve 18, and from the valve 18 through the upper connection 24 to the meter 25 from which it passes through line 27 to the visible flow indicator, thence throughthe connection 29 of the flexible hose 58, to the nozzle 57 The meter dial indicating the volume of fluid passing through the the by-pass connection at 16 and 12 leading from the pump to the strainer 11. When the nozzle 57 is subsequentl hung on the hook 62, the latter is lowere whereby the opereratlng valve are controlled throu ating rod 45 is depressed to operate switch 40 through the cam 42 of the cam shaft, thereby deenergizing the drive motor 20.
By this arrangement, the motor and oph the operating lever whereas the flow of fluid is in: dependently controlled through the nozzle lever 61. Vith the locking mechanism previously .described, both the motor control and fluid control are rendered inoperative since the operating lever and nozzle lever areboth locked against movement.
, It is obvious from the foregoing description of this invention that meterin pumps made in accordance therewith, prov1de positive and expedient means for dispensing gasoline or the like in a minimum of time and with absolute control of the quantity of the fluid being dispensed by the apparatus.
Although one embodiment of the invention has been herein described and claimed, it will be obvious to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.
I claim:
ing in combination a pump connected to a storage tank,,electrical apparatus for operating said pump, an electric switch for con trolling said pump, a control valve disposed in said outlet connection and'an operating shaftprovided with means for actuating said switch and valve and an operating rod connecting said shaft for actuating the latter, said rod being provided with means for engaging the dispensing nozzle whereby it is depressed to actuate the operating shaft.
