Abstract
Abstract A fuel dispensing nozzle includes a body having a spout slidably supported thereon with a valve, which is in the body and controls flow from the body to the spout, opening only when the spout is disposed in a tank to be filled. For fuel to flow through the spout, another valve, which is actuated by a manually operated lever, also must be opened in addition to the valve that is opened by the spout being properly disposed within the tank being filled.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
241 words
An automatic shut-off nozzle comprising a body having an inlet and an outlet, a first valve in the body controlling flow of liquid into the body through the inlet, manually operated means controlling the operation of the first valve, a spout communicating with the outlet, one end of the spout being slidably mounted on the body, a second valve associated with the outlet and operated by the sliding movement of the spout, the second valve being disposed within the body, means disposed within the body and acting on the body and one end of the spout to urge the spout to a position whereby the second valve is maintained in a closed position to close the outlet, the other end of the spout being insertable into a fill opening of a tank, means mounted on the spout adjacent the other end, the mounted means engaging the tank upon insertion of the spout into the fill opening and stopping movement of the spout into the fill opening after a predetermined further movement of the spout into the tank so that the body can be moved toward the tank relative to the spout and against the urging means to open the second valve and allow flow through the spout, and automatic operating means acting on the first valve to close the same upon the liquid level reaching a predetermined point in the tank regardless of the operating position of the manually operated means.
Claim 2
Dependent Claim
241 words
An automatic shut-off nozzle comprising a body having an inlet and an outlet, a first valve in the body controlling flow of liquid into the body through the inlet, manually operated means controlling the operation of the first valve, a spout communicating with the outlet, one end of the spout being slidably mounted on the body, a second valve associated with the outlet and operated by the sliding movement of the spout, the second valve being disposed within the body, means disposed within the body and acting on the body and one end of the spout to urge the spout to a position whereby the second valve is maintained in a closed position to close the outlet, the other end of the spout being insertable into a fill opening of a tank, means mounted on the spout adjacent the other end, the mounted means engaging the tank upon insertion of the spout into the fill opening and stopping movement of the spout into the fill opening after a predetermined further movement of the spout into the tank so that the body can be moved toward the tank relative to the spout and against the urging means to open the second valve and allow flow through the spout, and automatic operating means acting on the first valve to close the same upon the liquid level reaching a predetermined point in the tank regardless of the operating position of the manually operated means.
Claim 3
Dependent Claim
241 words
An automatic shut-off nozzle comprising a body having an inlet and an outlet, a first valve in the body controlling flow of liquid into the body through the inlet, manually operated means controlling the operation of the first valve, a spout communicating with the outlet, one end of the spout being slidably mounted on the body, a second valve associated with the outlet and operated by the sliding movement of the spout, the second valve being disposed within the body, means disposed within the body and acting on the body and one end of the spout to urge the spout to a position whereby the second valve is maintained in a closed position to close the outlet, the other end of the spout being insertable into a fill opening of a tank, means mounted on the spout adjacent the other end, the mounted means engaging the tank upon insertion of the spout into the fill opening and stopping movement of the spout into the fill opening after a predetermined further movement of the spout into the tank so that the body can be moved toward the tank relative to the spout and against the urging means to open the second valve and allow flow through the spout, and automatic operating means acting on the first valve to close the same upon the liquid level reaching a predetermined point in the tank regardless of the operating position of the manually operated means.
Claim 4
Dependent Claim
241 words
An automatic shut-off nozzle comprising a body having an inlet and an outlet, a first valve in the body controlling flow of liquid into the body through the inlet, manually operated means controlling the operation of the first valve, a spout communicating with the outlet, one end of the spout being slidably mounted on the body, a second valve associated with the outlet and operated by the sliding movement of the spout, the second valve being disposed within the body, means disposed within the body and acting on the body and one end of the spout to urge the spout to a position whereby the second valve is maintained in a closed position to close the outlet, the other end of the spout being insertable into a fill opening of a tank, means mounted on the spout adjacent the other end, the mounted means engaging the tank upon insertion of the spout into the fill opening and stopping movement of the spout into the fill opening after a predetermined further movement of the spout into the tank so that the body can be moved toward the tank relative to the spout and against the urging means to open the second valve and allow flow through the spout, and automatic operating means acting on the first valve to close the same upon the liquid level reaching a predetermined point in the tank regardless of the operating position of the manually operated means.
Claim 5
Dependent Claim
77 words
The nozzle as set forth in claim 1, wherein the second valve includes a valve member connected to the spout and a valve seat formed in the body, the valve member being movable with the spout, and the second valve is opened after the predetermined further movement of the spout into the tank is stopped and the body is moved relative to the spout toward the tank to move the valve seat away from the valve member.
Claim 6
Dependent Claim
51 words
The nozzle as set forth in claim 1, wherein the urging means comprises a coil spring surrounding the spout adjacent the one end thereof and mounted between the body and the spout and the spout has means to prevent activation of the automatic operating means unless the second valve is open.
Claim 7
Dependent Claim
98 words
The nozzle as set forth in claim 1, wherein the body is provided with an adaptor adjacent the outlet, the one end of the spout being slidably mounted in the adaptor and held therein by a cap, a retaining ring on the one end of the spout and engaging the cap, the urging means including a coil spring between the one end of the spout and the adaptor, one end of the spring engaging the adaptor and the other end engaging the retaining ring, the spring urging the spout to a position wherein tHe second valve is closed.
Claim 8
Dependent Claim
77 words
The nozzle as set forth in claim 4, wherein the second valve includes a valve member connected to the spout and a valve seat formed in the body, the valve member being movable with the spout, and the second valve is opened after the predetermined further movement of the spout into the tank is stopped and the body is moved relative to the spout toward the tank to move the valve seat away from the valve member.
