MOUNTING MEANS FOR LIQUID DISPENSING DEVICE AUXILIARIES Filed Jan. 21, 1948 2 SHEETSSHEET 2 INVENTOR 10 H. HIX WOLFE Talmw' fiTuM ATTORNEYS Patented Mar. 17, 1953 UNITED STATES PATENT, oEEJCs, MOUNTING MEANsf o nIsPENsmq I A v I DEVICE Acxrcmnms n. Hix Wolfe, Dayton, ohie gassi nart ith nayi ton Pump and Manufacturing Company, Dayton, Ohio, a corporation of .Ohio 7 Application January 21, 19 48,-Serial No.3,628 I This invention relates to dispensing pumps and particularly to dispensing pumps of the type employed in service stations and which include a pumping mechanism, a meter connected to receive the fluid flow from said pumping mechanism, and a computer connected to be driven by the meter and arranged to indicate the quan tity and price of the delivered fluid.

Pumps of the type referred to above are generally arranged with the pumping mechanism and drive motor therefor mounted in the bottom of the pump housing and with the meter placed thereabove and operatively connected with the computer and indicator which is mounted in the top of the pump casing. 1

The pumps are generally quite compact and there is little waste space within the pump housing. Accordingly, the computer, meter and pump, when mounted in the pump housing, are difficult to service due to lack of working space.

Also, these auxiliaries generally have mounting feet or projecting bosses thereon by means of which they are secured to the supporting frame work of the housing. These mounting feet or bosses make the removal of the auxiliaries diificult because the said auxiliaries must be lifted from the supporting frame work when they are to be removed from the pump housing. This operation is especially difficult when the pump assembl becomes compact and the various parts are closely arranged therein.

According to this invention the foregoing difficulty in connection with the assembly and servicing of metering and computing pumps is eliminated by a novel arrangement wherein the several pump components are slidably mounted in the pump housing.

The primary object of this invention is to provide a dispensing and computing pumping mechanism which is easier to assemble and service.

Another object'of this invention is the elimination from dispensing and computing pumps, and similar mechanisms, of the usual type of supporting means for the several auxiliaries of the pump, such as the pump proper, the meter,- and the indicating computer. 7

A still further object is theprovision of an following description taken in connection .with' the accompanying drawings in which:

"scnims.v (cuppa-52s Figure 1 is a .view looking at theindlcating side of atypical dispensing pump andwith thejfrontz panelremoved; p

t Figure; .2 is a view'looking at the pump illus trated'in Figure 1 from the right side thereof and with the near panel removed;

'FigureB is a plan viewindicatedby the line 33 on Figure 2 and showing more in detail the improved supportingmeans for: the:pump auxiliaries according to this invention; and

Figure 4 is a somewhat enlarged view showing the removable drive connection employed for connecting the computer with theoutput shaft of the meter.

Referring to the drawings, a pump adapted to be arranged according to this invention may comprise a base member l0 and secured to the said base member and upstanding therefrom are a plurality of angles 12 forming corner posts for the supporting frame work for the pump. A housing comprising a plurality of front, side and top panels as generally indicated at I 4 is mounted about the frame work and may be supported thereby in any suitable manner.

The front and back panels as indicated in Figure 2 may comprise windows I 6 through which the indicating faces as at l8 of the computer and indicator may be viewed.

Suspended from one side of the pump is a flexible dispensing hose 20 which may include a nozzle 22 on the free end thereof and which normally is suspended on ahose hook as indicated at 24.

The pump comprises an inlet pipe 26 which leads to a pumping mechanism 28 which is arranged to be driven by an electric motor 30. The pump has a discharge at 32 which is connected by a conduit 34 with a-meter 36. The conduit 34 preferably includes the flanged connectors at 38 which can be disconnected thereby to separate the meter and pump if so desired.

The discharge side of the meter is connected by a conduit 4a which leads upwardly within the frame of the pump to a casting member 42 which in turn is connected by means of a conduit, not shown, with the stationary end of the dispensing hose 20. The cast member may include sight glass elements 44 which are arranged, as shown, above each of the indicator faces I8.

3 dials projecting through the windows 52 in the indicator faces I8.

The internal construction of the pump meter and computer form no particular part of the present invention and they are therefore shown in elevation and without any detail construction.

Each of the foregoing auxiliaries is subject to being serviced at periodic intervals and accordingly it is desirable that they be easily removable from the pump frame. Accordingly, the pumping mechanism 28 has the laterally projecting parts 54 which rest on guides or angle members 56 which extend across the pump frame from front to back thereof. right side of the pump in Figure 1 is supported between the corner posts l2 at that side of the pump, while the guide member 56 at the left side of the meter in Figure 1 is carried on a frame work 58 which is connected with the side posts I2 at the other side of the pump and which forms a mounting platform for the drive motor 30.

The pump 28 is rigidly connected with the guide members 56 by means of the cap screws 60 which pass through the said guides and into threaded bores in the laterally projecting parts 54 of the pump frame. It will be apparent that if the cap screws 60 are removed the pump 28 can be removed from the pump frame by sliding it in a horizontal direction off the guide members 56.

Turning now to the meter 35, it will be observed that the said meter has projecting from the bottom thereof a plurality of bosses 6-2 which rest on a tray or platform 64 and which are secured thereto by the cap screws 66 passing through the platform and into the said bosses. The tray or platform 64 extends the width of the meter 36 and has laterally projecting feet or skid portions 68 thereon. These skid parts rest on a fixed platform or shelf 10 and are slidable beneath the cleats 12. The arrangement thus provides for a guide by means of which the: meter can be placed in the pump frame or removed therefrom by sliding it in a horizontal plane.

The fixed platform 18 comprises a plate having the front and back edges thereof turned down for the purpose of giving it rigidity and extending from side to side within the corner posts 12 of the pump frame. The said platform is supported on the corner posts by the bracket members 14 which extend between the corner posts at the side of the pump frame and have the turned under lips H which engage the underneath side of the platform "3E; on each side thereof. The shelf or platform H3 is preferably cutout as at 13 to provide a recess within which the outlet fitting 32 of the pump 28 can be received.

It is to be noted that the outlet fitting 32 of the pump is positioned to one side of the meter so that the meter can be inserted in the pump frame and removed therefrom without interfering with the pump in any manner whatever.

For rigidly clamping the meter in position there may be a boss 89 secured to the upper side of the shelf and a cap screw 82 passing through the tray 54 and into the boss 88. In this manner the position of the meter on the shelf or platform 18 can be definitely fixed. This provides for rigid alignment of the said meter with the pumping mechanism and when both have been placed on their corresponding guide members and clamped thereto the standard interconnecting conduit member 3 can be employed for effecting fiuid connection therebetween.

Turning now to the computer mechanism 58,

The guide member 56 at the it will be seen that this auxiliary, similarly to the meter 36, comprises dependant boss members 8 1 which rest on a tray 35 and which are secured to the said tray by the cap screws 88. The tray 86 comprises the laterally extending skid parts Si receivable beneath the guide members $2 which are mounted on the upper side of a shelf or plat form 94 carried in the pump frame by the bracket members 98 which correspond to the bracket members i4 associated with the shelf 7%.

Also, a clamping and aligning boss and cap screw 98 are employed whereby the position of the computer on its shelf is definitely fixed. It will be apparent that once the meter and computing devices are mounted on their corresponding shelves and clamped thereto by their corresponding clamping screws, a connection can be made between the output shaft of the meter and the input shaft of the computer. The means for effecting this connection is illustrated in Figure 4 wherein it will be seen that the input shaft 48 of the computing device has a slotted end thereon into which extends the ball and pin fitting I538. The ball and pin fitting is a part of a shaft I32 which has a similar ball and pin fitting W; at its lower end. The ball and pin fitting at the lower end engages a slotted sleeve let which is pinned to the output shaft 46 of the meter by a pin I88. By removing the pin its the sleeve H36 can be moved downwardly over the meter shaft and thereby release the shaft 62 so that the meter and computer can be disconnected. A clearance hole H9 in the shelf 9 provides for sufiicient space for easily installing or removing the shaft H32.

From th foregoing description of the structural arrangement of this invention it becomes apparent that each of the pump auxiliaries comprising the pump 28, meter 36, and computing device 59, are mounted in the frame of the pump on a slide arrangement so that they can be placed in the pump by a sliding motion from one side thereof. Also, each of these auxiliaries can be removed from the pump frame by disconnecting it from its associated auxiliary and unclaniping it from its supporting shelf and removing it by ahorizontal sliding motion. This eliminates lifting and supporting these heavy units during their placement within the pump frame or their re-= moval therefrom.

Also, and especially in connection with the indicating device or the meter, the auxiliaries can be loosened from their supporting shelves and partially removed from the pump as indicated by the dot-dash outline for the meter in Figure 2 whereby they are in position to be more easily serviced. This facilitates the servicing of the de vices so that they can be restored to service much more quickly in case repairs are needed.

It will be understood that this invention is susceptible to modification in order to adapt it to different usages and conditions and, accordingly, it is desired to comprehend such modifications within this invention as may fall within the scope of the appended claims.
