' Application filed December 20, 1924. Elerial No. 75?,189.
This invention relates to improvements in tank closures of the type provided with a vent opening to permit the flow of air to or from the tank as the liquid contents there- 5 of varies, and more particularly to means adapted to prevent leakage of the liquid through the vent when the tank is in an abnormal position such that the vent is at or below the level of the liquid.
Tank closures of the character described above and made in accordance with the present invention as defined by the claims are particularly useful in connection with the fuel tanks of outboard motors. These motors are portable and provided with means for quickly attaching or detaching them to the stern of a boat. It has been found from experience that when these motors are carried about or placed upon the the usual vent opening in the cap or closure for the gasoline tank. When the motor is in a vertical position at the stern of the boat. the cap is above the levelof the gasoline 2 in the tank so that no leakage through the vent opening is possible.
One of the objects of the invention is to provide an improved tank closure having a vent opening with means for closing the vent when the motor or tank is tilted from its normal, vertical position.
Another object is to provide an improved tank closure of the character described in which the vent is automatically closed by gravity-controlled means upon tilting of the motor or tank from normal, vertical position.
Another object is to provide a tank closure of the character described which is simple, durable and which may be economically manufactured.
Other objects and advantages will hereinafter appear. V
For the purpose of illustrating the invention, an embodiment thereof is shown in the drawings, in which Figure 1 is a rear end elevation, partly in section, of the upper portion of an outboard motor showing the improved tank closure or 6 cap applied to the gasoline tank, the motor and tank associated therewith being in normal, vertical position;
Fig. 2 is a sideelevation, partly in section, of the improved tank closure or cap,
ground, leakage of gasoline occurs through FFZICE'.
Fig. 3 is a view similar to'Fig. 2, showing the position of the various parts when the motor is tilted;
Igig. 4 is a section on line 4-4 of Fig. 2; an
Fig. 5 i a section on lin'e 5-5 of Fig. 2. The invention comprises, in general, a cas- 1ng1 provided with a vent opening 2, means such as a valve 3 for opening and closing the vent, and means such a substantially spherical actuating member 4 .arranged for cooperation with valve 3 to automatically move the same to close the vent when the cap is tilted to a position such as shown in Fig. 3. Casing 1 may comprise a body orplaced upon its side and the cap tion 5 which is threaded into the neo 6 of the tank 7, and an upper wall or top 8 having a boss 9 at the center thereof'through which the vent opening 2 is made. The lower end of body portion 5 is internally threaded to receive a similarly threaded plug or bottom member 9 having a concave surface 10 arrangedopposite vent opening 2 and upon which actuating member 4 is seat: ed for the purpose hereinafter explained. Plug 9 may be provided with the usual openings 11 to receive a spanner wrench for adjusting themember axially with respect to.
casing 1. The bottom member 9 may be provided with an opening at the center thereof to receive the upper link 12 of the usual anchor chain 13 for preventing the cap from becoming lost when the same is taken oil" for the purpose of filling the tank, the end 14 of the link being riveted over, as shown, to secure the chain to the bottom member.
The valve 3 may comprise a shank 15 loosely fitted in the vent opening 2 and a head 16 which her 4.
A gasket 17 ma be placed between neck 6 of the tank an the top 8 of the casing to Igirevent leakage of gasoline between these pa s.
The plug or bottom member 9 is adjusted with respect to casing 1 so that when the cap is in normal, vertical position as shown in Fig. 2, valve 3 is supported by actuating member 4 inposition to open the vent and permit the flow of air to or from the tank is engaged by actuating memshowing the position of the various parts by way of suitable openings 18 in the body vided to lock the former in adjusted position.
When tank 7 and the cap secured thereto are tilted so that the latter is in a position such as shown in Fig. 3, actuating member 4 will dropi by the action of gravit and roll upon the concave surface 10 and orce valve 3 in osition automatically to close the vent opening, as shown, the outlet end 20 of the vent opening being restricted to provide a suitable seat against which the tapered end of valve 3 fits. From the foregoing it will be seen that when the cap is tilted or moved from its normal, vertical position the actuating member 4 will move by the action of gravity alon the concave surface 10 and automatically orce valve 3 in position to close vent opening 2. Leakage of gasoline from the tank is thereb prevented.
Various changes in t e size, shape and arrangement of the parts may be made without departing from the spirit'of the invention or the scope of the claims.
The invention claimed is: I
