GASOLINE PUMP Filed June 23, 1927 2 Sheets-Sheet 2 Patented Apr. 15, 1930 UNITED STATES PATENT OFFICE E RL E. EIGKMEYER, or DAYTON, 02110, ASSIGNOR 'ro THE DAYTON mnvrr & MFG. COMPANY, or DAYTON, 01110, A conrona'rron or'onro GASOLINE PUMP Application filed June 23,
My invention relates to gasoline pumps and in particular to sight glasses therefor.
It is the object of my invention to provide a visible float mechanism for use as a sight glass in which the level of the gasoline at the top thereof is always visibly indicated to the purchaser, so that the top is not hidden by the dome or cap of such visible sight glasses heretofore known in the art.
Heretofore, the chamber consisting of the glass cylinder, the metal retaining cage and the dome has been filled with gasoline up to the level where the gas would run out the opening in the dome into the hose but this left the level of the gasoline at a point where thepurchaser could not see it so that it would be possible for an unscrupulous salesman to cheat the purchaser out of the amount of gasoline due him. This would amount to several inches of gasoline each time and a continuous cheating to this extent would become a considerable amount during the course of a days business.
It is my object to provide means by which the gasoline will be evacuated from the sight glass down to a point where the top of the gasoline will be always visible. Referring to the drawings: Figure 1 is a side elevation of my device; Figure 2 is a section on the line 22 thereof;
Figure 3 is a top plan view. Referring to the drawings in detail, 1 is a supply pipe threaded at 2 into the base 3 of a cage having spaced projecting arms 4 joined together by a ring or cap 5 at the top thereof. A glass cylinder 6 is mounted within the cage so that the gasoline therein may be observed and so that the rotation of the 40 spinner 7 may be observed, which spinner mg a gasket 10 and upright dome wall 11 forming part of the dome 12. This dome 12 closes the 1927. Serial No. 200,785.
is provided with a side aperture 13 to which is connected the hose 1&1. This hose extends down from the dome, and has a siphon action in removing the contents of the cylinder.
This siphon action ceases when the contents reach a certain level determined by the admission of air into the cylinders and around the edge. of the skirt 15. Within the dome there is a depending inwardly projected open mouthed skirt 15,the lower edge of which designated 16 coincides with the line 8 and is vvisible through the glass 6 at a point below -to the cage by the bolts 25, so that a strong integral housing is provided, the strain of the hose being communicated through. the metal cage to the supporting pipe 1 without Iimparting any crushing strains upon the glass 6.
If desired, a red line can be drawn across the glass corresponding to the line 8 in order -to indicate to the purchaser where the level .of the gasoline should be within the visible sight glass.
Method of operation-1n operation when the gasolineflows out, of the hose, it will continue to flow even after the gasoline descends below the lower edge of the opening 13 communicating with the hose 14; due to the siphoning action facilitated by the downwardly extending skirt 15. This siphoning action, due to the suction created, will cause the ball 22 to lift and air be sucked into the space 17. The siphoning action will be broken off when the gas level reaches the edge 16 of the skirt 15 because at that point the air in the passageway 17 can flow around the edge 16 and the siphoning action will be terminated.
It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varyin conditions and uses.
I-Iaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a sight glass mechanism, the combination of a gasoline supply and exit line, a sight glass, a dome member mounted on said sight glass, and means on the dome forming an air passage and extending to a point within said sight glass which is visible therethrough to admit air and said dome having means near the top thereof for connection to the exit line.
2. In a sight glass mechanism, the combination of an inlet pipe, a cage having aper tures therein, a sight glass carried in said cage, a dome mounted on said sight glass having an exit passageway above the sight glass, a siphon hose connected to said passageway and an inwardly extending downwardly projected skirt carried by said dome s aced from one wall thereof to form an air c amber, the lower end of said skirt being visible through said sight glass, and means for controlling the communication of said air chamber with the outside atmosphere consisting of a valve passageway having a valve seat controlling an atmospheric port, and a ball mounted in said passageway adapted to rest on said seat and close said port whereby the siphoning action of the fluid making its departure through the hose will draw out the fluid from the sight glass and draw in the air through the said port in which the air chamber handling the fluid reaches the bottom of said skirt whereupon the air in said air passageway will break the siphoning action and the fluid will cease to flow.
3. In a sight glass mechanism, the combination of an inlet pipe, a cage having apertures therein, a sight glass carried in said cage, a dome mounted on said sight glass having an exit passageway above the sight glass, a siphon hose connected to said passageway and an inwardly extending downwardly projected skirt carried by said dome spaced from one wall thereof to form an air chamber, the lower end of said skirt being visible through said sight glass, and means for controlling the communication of said air chamber with the outside atmosphere consisting of a valve passageway having a valve seat controlling an atmospheric port, and a ball mounted in said passageway adapted to rest on said seat and close said port whereby the siphoning action of the fluid making its departure through the hose will draw out the fluid from the sight glass and draw in the air through the said port in which the air chamber handling the fluid reaches the bottom of the skirtwhereupon the air in said air passageway'will break the siphoning action and the fluid will cease to flow, and spinner mechanism suspended from said dome for indicating the flow of fluid while said flow is taking place through the sight glass mechanism.
4. In a sight glass mechanism, the combination of a supply line, a siphon and exit line, a sight glass, a dome member mounted on said sight glass having a part extending to a point within said sight glass which is visible therethrough, said dome having means near the top'thereof for connection to said exit line, said part forming an air chamber from the top of the dome to the bottom of the portion of the dome which extends into the sight glass, and means for permitting the entrance of air into said air chamber when the siphoning action is taking place.
5. In a sight glass mechanism, thecombination of a gasoline supply line, a siphon exit line, a sight glass, a dome member mounted on said sight glass having a part extending to a point within said sight glass which is visible therethrough, and having means near the top thereof for connection to said exit and siphon line, said part of said dome forming an air chamber from the top of the dome to the bottom of that portion of-the dome which extends into the sight glass, and means for permitting theentrance of air into said air chamber when the siphoning action is taking place and to prevent siphoning when the gasoline reaches a certain level.
In testimony whereof, I aflix my signature.
EARL E. EIGKMEYER.
