Abstract
Abstract A gasoline level indicator for a motorcycle having the fuel tank in front of the operator''s seat consists of a transparent plastic tube vented at the top running downward over the tank and connects to the fuel line from beneath the tank. The tube is contoured to lie flat on the outside of the tank in full view of the operator so that the operator can observe the level of fuel in the tube which is the same as the level in the tank.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
215 words
A fuel level indicator for the fuel tank of a motorcycle comprising, a length of flexible transparent plastic strip having formed therein a tube passage from one end to the other of the strip, said tube being bented at one end and connected at the other end to the fuel line from the bottom of the tank, said length of plastic strip being attached along a portion thereof contiguous to the outside of the tank from a point substantially at the top of the tank to a point substantially at the bottom of the tank with the vented end of the tube at the top of the tank and extending downward therefrom on the tank substantially within the view of the operator of the motorcycle, whereby fuel from the tank fills the tube to a level in the tube even with the level of fuel in the tank, said level in the tube being visible to the operator, and a connector having one arm adapted for connection to the other end of the transparent tube, two other arms adapted for connection in the fuel line and containing in said one arm means for damping the flow of fuel into and out of the transparent tube without damping the flow of fuel in the fuel line.
Claim 2
Dependent Claim
215 words
A fuel level indicator for the fuel tank of a motorcycle comprising, a length of flexible transparent plastic strip having formed therein a tube passage from one end to the other of the strip, said tube being bented at one end and connected at the other end to the fuel line from the bottom of the tank, said length of plastic strip being attached along a portion thereof contiguous to the outside of the tank from a point substantially at the top of the tank to a point substantially at the bottom of the tank with the vented end of the tube at the top of the tank and extending downward therefrom on the tank substantially within the view of the operator of the motorcycle, whereby fuel from the tank fills the tube to a level in the tube even with the level of fuel in the tank, said level in the tube being visible to the operator, and a connector having one arm adapted for connection to the other end of the transparent tube, two other arms adapted for connection in the fuel line and containing in said one arm means for damping the flow of fuel into and out of the transparent tube without damping the flow of fuel in the fuel line.
Claim 3
Dependent Claim
44 words
A fuel level indicator as in claim 1 wherein, one side of said strip along the length thereof is substantially flat, and the length of transparent strip has an adhesive on the said flat side for attachment to the outside of the fuel tank.
Claim 4
Dependent Claim
99 words
A fuel level indicator as in claim 2 wherein, only a portion of the length of the transparent strip has an adhesive on the said flat side for attachment contiguous to the outside of the tank, and the end of said tube extending therefrom is not so attachable to the outside of the fuel tank, said portion and said extending end being provided in sufficient length for attachment and connection of the transparent strip to a variety of shapes and sizes of tanks by cutting off the ends thereof to attach and connect the strip to a particular tank.
Claim 5
Dependent Claim
89 words
A fuel level indicator as In claim 1 wherein, the transparent strip is so shaped in cross section that the axis of the inside of the transparent tubing is sufficiently raised from the outside surface of the tank when the flat side thereof is contiguous with the outside surface of the tank that the fuel level in the tube is readily visible to the operator viewing the fuel in the tube through the rounded side of the tube in a direction along the said outside surface of the tank.
Claim 6
Dependent Claim
24 words
A fuel level indicator as in claim 1 wherein, the transparent tube is vented at the one end into the top of the tank.
Claim 7
Dependent Claim
59 words
A fuel level indicator as in claim 1 wherein, at least a portion of the outside surface of the strip is curved, and the radius of the tube is substantially less than the radius of curvature of the curved side of the strip, whereby the transparent strip magnifies the image of fuel in the tube visible to the operator.
