' VENTING ATTACHMENT FOR GASOLINE TANK FILLING NECKS Filed Jan. 9, 1948 g v 9 I INVENTOR. William 1 1:2 111 K Patented Nov. 27, 1951 UNITED S TATES VENTING ATTACHMENT FOR GASOLINE TANK FILLING NECKS William Poznik, Brooklyn, N. Y.
Application January 9, 1948, Serial No. 1,305 7 Claims. (01. 220-86) This invention relates to an improved construction of filling necks for gasoline tanks and more particularly to a filling neck especially adaptedforuse withmotor vehicle gasoline tanks and having means for venting the tank the filling thereof.
Trapped air and gasoline froth causes much waste of gasoline and waste of time in filling gasoline tanks from the conventional discharge nozzle of gasoline pumps and results in the appearance of carelessness on the part of the attendant when overflow of the tank results fromeither of such causes.
Accordingly, it is the primary object of the present invention to provide a filling neck for gasoline tanks having venting means whereby air trapped in the tank can be vented around the filling nozzle without affecting the flow from said nozzle and so that gasoline froth will be retarded andbroken down into liquid and air permitting escape of the air and retention of the gasoline particles.
More particularly, it is an object of the present invention to provide a gasoline tank filling neck having an insertincluding anon-porous component adapted to closely engage around the discharge end of the nozzle and through which the gasoline is conveyed into the tank and having a porous or perforated surrounding body through which trapped air can escape around said nonporous :component and the nozzle but which will prevent or materially retard any escape of gasoline therethrough.
Another object of the invention "is to provide a device for the aforedescribed purpose capable of being employed as anattachment forlfilling necks of gasoline tanks.
Another object of the invention is to provide a venting attachment for filling necks of gasoline tanks which will readily adapt itself to discharge nozzles of different sizes and which will closely engage therearound to prevent escape of gasoline between said attachment and the nozzle.
Another object of the invention is to provide a device of the aforedescribed character which is normally closed and which is adapted to be opened by the application of a discharge nozzle thereto.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:
Figure 1 is an enlarged longitudinal, substantially central sectional view of the attachment;
during Figure? is a similar view on a reduced scale and partly in side elevation showing the attachment applied to the inlet end of the filling neck of a gasoline tank;
Figure 3 is a cross sectional View of the attachment taken substantially along a plane as indicated by the line 3-3 of Figure l, and
Figure 4 is a perspective View, partly broken away of the attachment.
Referring more specifically to the drawing, for the purpose of illustrating a preferred application and use of the venting device, designated generally 5 and comprising the invention, a portion of a gasoline tank such as is utilized with a motor vehicle is indicated at 5 equipped with a \filling neck 1 which extends upwardly or outwardly from an end or'side thereof and which may, if desired, be formed of end sections connected by the collard and clamps 9. The outer end of the filling neck 1 is internally and externally enlarged as seen at Ill to accommodate the attachment 5 although, if desired, said filling neck i may be of the same diameter throughout its length and either enlarged to accommodate said attachment 5 or the attachment may be reduced to fit the reduced outer end of the neck 1.
The attachment 5 includes a cylindrical outer wall or body I! which is provided at one end thereof with an out-turned flange 52 which seats in a flanged ring] 3 and may be secured thereto in any suitable manner as by soldering or welding, as indicated at I4. The annular flange portion 15 of the ring 13 is held in spaced relationship and concentrically around .a portionof the body H by the outturned flange 12 to combine therewith 'to form an annular recess l8 adapted to receive the outer end of the neck portion is when the body .H :is insertedinto said portion Ill, as illustrated in Figure 2 and so that said flange l5 will engage around said edge portion of the The body ll, including the ring E3 may be secured in any suitable manner as by :soldering or welding as at it! to the neck portion Ill for securing the attachment 5 thereto. The inwardly extending annular flange it of the ring I3 is provided with retaining means it] by which a closure cap, not shown, may be quickly and easilysecured thereto or removed therefrom.
A porous body or sleeve disposed in and has its periphery suitably secured to the internal side of the shell or annular wall i i and the bore thereof is provided with a beveled outer end 2! disposed adjacent to but spaced from the ring l3.
The opposite end of the sleeve or body member 20 is provided with an annular inwardly extendlar member 255.
ing, inwardly tapered recess 22 which combines with the opposite, tapered end of the bore 2! to form an annular neck 23 which taper in thickness toward the inner end of said sleeve or body member 20 and which is internally recessed, as seen at 24 to receive the enlarged, substantially conical shaped end 25 of a non-porous member or tube 26. The restricted, inner end of the tube 26 is provided with diametrically opposed substantially V-shaped cut-out portions 21, as best seen in Figure 2 forming corresponding flap members 28 at the restricted end of said tubular member 26. The porous element 29 is preferably formed of a resilient material such as sponge rubber but may be formed of other porous or perforated material including certain ceramic material. If the element 26 is formed of a porous-resilient material the resiliency of its neck portion 23 will readily function to cause the tubular member 25 to normally assume the position of Figures 1 and land with the flaps 28 disposed in abutting engagement for closing the inner end of said tubu- Hovvever, the tubular member 21: is preferably formed of a non-porous resilient material such as rubber and which, due to its own resiliency, can cause it to normally assume the closed position just previously described.
From the foregoing it will be readily apparent that the vent attachment wiil assume the position as illustrated in Figure 1 when applied to the 1 neck portion H) and when the tank 6 is not being filled so that the tank 6 can be vented through the porous component 26 but the gasoline, not shown and gasoline froth Within the tank 6 will be prevented from passing to above the porous "porous neck portion 23 to be expanded by the discharge end of the nozzle 29 for spreading the flaps 28 to open the inner, restricted end of the tube 26 and so that gasoline from the nozzle 29 can pass therethrough into the neck 1 and then into the tank 6. Furthermore, the pressure of the gasoline in the restricted, inn-er end of the tube 26 will further act to open said tube even though thetube is not opened by the discharge end of the nozzle 29. The conical tube portion 25 will engage yieldably about the discharge end of the nozzle 29 to form a seal therearound to prevent air or gasoline froth from passing outwardly through the tube 26 and around the nozzle 29. However, the tank and filling neck can be vented by the air passing into the chamber 22 and through the porous body or sleeve 20 but gasoline froth will be retarded and broken down so that only the air therefrom will escape through the porous body 29 to the atmosphere while the gasoline particles will be prevented from passing therethrough and will find their Way by gravity back through the neck 7 to the tank 6. Thus it will be readily apparent that the tank 6 can be refilled more rapidly than is possible under conventional methods Without danger of gasoline gushing from the open end of the filling neck as a result of trapped air or frothing of the gasoline.
Obviously, if desired, the sleeve or body 26 with the tube 25 applied and secured thereto, as illustrated, could be secured directly in the filling neck 1 adjacent its open end and various other modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.
