Abstract
An apparatus for indicating the amount of fuel in a fuel tank for a barbecue grill is disclosed. The apparatus includes a first housing member having indicator marks on an indicator wall thereof, a second housing member slidably engaging the first housing member and further securing the fuel tank, and a spring member connected to the first and second housing members to provide a resistive force to oppose the downward movement force of the fuel tank. The second housing member has a gauge wall with openings such that the gauge wall at least partially overlies the indicator wall of the first housing member to progressively expose indicator marks through the openings. The exposed indicator marks provide a readout of the amount of fuel remaining in the fuel tank.
Claims36
An apparatus for indicating the amount of fuel in a fuel tank for a barbecue grill, the fuel tank having a weight which provides a downward force, the apparatus comprising:
- a first scale member having indicator marks on an indicator wall thereof;
- a second scale member slidably engaging the first scale member, the second scale member having a gauge wall wherein the gauge wall at least partially overlies the indicator wall of the first scale member, and wherein the gauge wall has at least one opening;
- and,
- a spring member connected to the first and second scale members, the spring member providing a resistive force adapted to oppose the downward force of the fuel tank.
An apparatus for indicating the amount of fuel in a fuel tank for a barbecue grill, comprising:
- (a) a first housing member having an indicator wall with indicator marks thereon;
- (b) a second housing member slidably engaged with the first housing member, the second housing member having a gauge wall at least partially covering the indicator wall of the first housing member, the gauge wall having at least one opening such that the at least one opening in the gauge wall exposes an underlying area of the indicator wall of the first housing member, wherein one of either the first or the second housing member is adapted to remain in a fixed position, the other of either the first or the second housing member being slidably movable relative to the housing member that is adapted to remain in a fixed position, and wherein the housing member which is slidably movable relative to the other housing member is adapted to removably secure the fuel tank thereto, the fuel tank having a weight which provides an opposed movement force;
- and,
- (c) a spring member connected to the first housing member and the second housing member, the spring member providing a force in resistance to the opposed movement force of the fuel tank.
An apparatus for indicating the amount of fuel in a fuel tank for a barbecue grill, comprising:
- a first housing member having an indicator wall with indicator marks thereon;
- a second housing member slidably engaged with the first housing member, the second housing member having a first wall, a second wall substantially parallel to the first wall, and a third wall adjacent the first wall and the second wall, such that the first, second and third wall form a C-shape, the third wall at least partially covering the indicator wall of the first housing member and the third wall having a plurality of openings such that at least one opening exposes an underlying area of the indicator wall of the first housing member, wherein the first housing member is adapted to remain in a fixed position, wherein the second housing member is slidably movable relative to the first housing member, and wherein the second housing member is adapted to removably secure the fuel tank thereto, the fuel tank having a weight which provides an opposed movement force;
- a spring connected to the first housing member and the second housing member, the spring member providing a spring load force in resistance to the opposed movement force of the fuel tank;
- a first shaft connected to the first housing member;
- a second shaft connected to the first housing member;
- and,
- a plurality of rollers, one of the plurality of rollers attached to an end of the first shaft and an end of the second shaft, wherein the first, second and third walls of the second housing member partially encapsulate the rollers.
