Y VISIBLE DISPENSING DEVICE Filed May 29, 1929 UNITE,
ROBERT W. COBB, OFA JAMESTOWN, NEW
STATES NEW YORK YORK, ASSIGNOR TO JULIAN PUMP AND l MANUFACTURING COMPANY, OF JAMESTOWN, NEW YORK, A CORPORATION OF VISIBLE DISPENSING :DEVICE Application mea May y2e,
This invention relates to an improvement in a visiblefdisp'ensing device for gasoline pumps and the like. l
In its preferred embodiment this invention ,5 contemplates the provision of a device adapted to be mounted upon a gasoline pump of the Wet ordry'hoseftype whereby the actual dispensing of gasoline isy visibly brought to the attention ofthe purchaser thereof.
Prior to thisfin-vention devices of this generalV type havebeen in use but, due to regulations in certain States relating to the visible dispensing of gasoline, these devices fail to fulfill the purpose intended. Since the States arenot'wholly in accord in their requirements it is essential that avisible dispensing device embodying all the required features be provided. Applicant has therefore produced a device which, while indicating the iiow of gasoline therethrough,y also prevents the ac- @umu-lation of air in the dispensing line and which is equally applicable for use in conjunction with pumps of the wet or dry hose type.
Theprinci-pal' object of this invention is to provide a-device of this class indicative of the amount of gasoline contained within the transparent domey through which the gasolinel must passduring; the' dispensing operation.
Anotherobj'ect of this invention is to providev a device of this class which clearly indicates to the purchaserl that gasoline is actually being'dispensed.
A further=objectjofthis invention is tolprovide a device of this class of'economical construction and adaptable for both wetk and dry hose type pumps and which complies with the laws of certain States relating to the visibledispensing of gasoline.
@ther and further objects ofthis invention will appear from a consideration of the following specification taken in conjunction with the5 accompanyingy drawing, andi in which Fig. 1 is a front elevation of a gasoline pump ofthe wet'hose type showing one modiicati-on of this invention mounted thereon;
Fi-g.,2"isan enlarged vertical sectional view of the invention, showingthe inlet and out- 1929. serial No. 366,880.
let passages for the gasoline and the means by which oscillation of the gasoline within the dome is obtained; and
Fig. 3 is a plan view of the device with the glass dome removed disclosing further struc* turalI details of this invention.l
Referring to the drawing and particularly to Figure 2 thereof, this invention comprises a base generally indicated by the reference numeral '10. The base 10 is provided with a gasoline inlet passage 12 and outlet passage 13.' Encircling the passages 12 and 13 and formed in the upper face 14 of the base is an annular depression orrecess 16. Centrally of the face 14 an angular boss 17 is provided. A threaded opening 18 is provided in the slanted face of thevboss 17 and a deflector or baffle plate 2O is secured to this face by means of the screw 21. The plate 20, being mounted substantially at a Aforty-tive degree angle to the face 14 ofthe base 10, closely approaches the substantially vertical wall of the glass dome 25. The purpose of this is to insure sufficient oscillation of the liquid as it passes through the dome to indicate to a purchaser that the pump is working and gasoline is being dispensed.
Mounted within .the annular recess 16 is a suitable gasket 26. The glass dome 25, lterminating in a flanged rim 27 is adapted to restwithin the depression 16 upon the gasket 26. A second gasket 29 is placed upon the upper face of the rim 27 of the glass dome and a clamping ring 31 rests upon the gasket 29. v
Extending downwardly from the upper face 14 of the base 10 and exteriorly ofthe recess 16 are a plurality of threaded openings 33. The clamping ring 31 is provided with outwardly extending bosses 34 each of which has formed therein a vertical opening 35, the number of openings 35 corresponding to the number of drilled openings 33. The glass dome 25 is drawn down into sealing engagement with the gasket 26 through the use of'bolts 37.
LocatedV within the glass. dome and prior to the mounting thereof lupon the base 10 is a ball 38 formed from cork or other suitable lOatng Substance When this device is used in connection with gasoline pumps of the dry hose typre, the normal position of rest of the ball 38 is substantially as shown in dotted lines, Figure 2 of the drawing, covering the inlet opening 12. However, when this device is in use upon a pump of the wet hose type as illustrated in Figure 1, the ball occupies a position of rest adjacent the head of the glass dome as shown in full line of Figure 2. A wet hose type pump maintains gasoline at all times in the 'system directly down to the nozzle of the dispensing hose, whereas, a pump of the dry hose type is required to be operated to cause gasoline to flow throughthe glass dome 25, passage 13 and hose 39.
The above described device, although applicable for use upon pumpsofeither the dry or wet hose type, is usedmore often upon the` latter type. This is due to the fact that nearly all types of dry hose pumps are provided with a visible gasoline container from which dispensing takes place. However with apump such as shown in the drawing, there is no visible means of indicating that gasoline is-actually being dispensed withoutfthe attachment of applicants device.
When the pump is of the gasoline.V Thus, when further dispensing is carried on, the pump will fail to give absolutely accurate measure. The laws of certain States require that no such condition eX- f ist and consequently applicant through the use of the float 38 and plate 20 is able to instantly cause the removal of an air pocket in the dispensing dome. As gasoline enters the passageway 12 it moves upwardly toward the top of the dome and, ,following the contour thereof, is directed upon the plate 20. A part of the gasoline passes out through the passageway 13 andl theremainder sets up a swirl- .ing motion causingy the float 38 to oscillate rapidly about the dome. With each oscillation of the float it causes a small'amount of air to pass out through the passageway13 until only gasoline remains within the dome. It is to be understood that'themotionof the float about the dome is very rapid and consequently any air pocketed in said dome is removed almost instantly. It is to be further understood that, except under conditions as above described, the dome will be filled at all times with gasoline and the float will rest against the top of the dome. 1
Attention is directed to the fact that a Y first operated or directly y after having run dry, no gasoline is contained customer need only Awatch the glass doine and the float within it to determine whether or not gasoline is being properly dispensed.
The purpose of this device when used in conjunction with pumps ofthe dry hose type is identical. However, when this type of pump is not operating the float rests upon the mouth of the passageway 12 where it can receive and be oscillated by the first flow of gasoline into the dome. I n y While only one modification of this invention has been shown and described, applicant does not intend to be limited thereto since it is obvious that other modifications and adaptations may be made without departing from the spirit and scope ofthis invention as vset forth in the following claims. y f i Having thus set forth my invention what I claim is new and for which I desire pro-z.
