Bottled gas cart

In a movable cart for supporting at least one pressurized gas cylinder, the combination comprising:

• a housing having an interior compartment which is proportioned to receive and contain said gas cylinder, said housing having a lower end with means for journaling wheels thereto and wherein said housing has a front face and opposite side surfaces which extend upward from said lower end thereof,
• means for selectively securing said gas cylinder at a fixed position within said housing,
• means for delivering a flow of gas from said cylinder to a location outside of said housing,
• first and second spaced apart wheels journaled to said lower end of said housing, said wheels being at locations which cause said housing to be raised from the underlying floor or the like and to be supported by said wheels when said housing is in a tilted orientation,
• further including a downwardly extending leg disposed at said front face of said housing substantially midway between said side surfaces thereof, a first pivot coupling connecting an upper end of said leg to said housing, said first pivot coupling being oriented to enable pivoting of a lower end of said leg towards said front face of said housing and outward therefrom, a third wheel located substantially equidistant from said side surfaces of said housing and a swivel connector coupling said third wheel to a lower end of said leg,
• wherein said leg has a first aperture situated at the location of said slider member on said leg when said lower end of said leg has been pivoted toward said front face of said housing and has a second aperture situated at the location of said slider member on said leg when said lower end of said leg has been pivoted outward from said front face of said housing, and a movable latch pin carried by said slider member in position for engaging in said apertures.

• means for selectively securing said gas cylinder at a fixed position within said housing,
• means for delivering a flow of gas from said cylinder to a location outside of said housing,
• first and second spaced apart wheels journaled to said lower end of said housing, said wheels being at locations which cause said housing to be raised from the underlying floor or the like and to be supported by said wheels when said housing is in a tilted orientation,
• wherein said housing is proportioned to receive a pair of said gas cylinders in upright side by side relationship and has a floor and a front region and opposite side walls and a rear wall which extend upward from said lower end of said housing, said rear wall and at least a rearward portion of each side wall being formed by a pair of angled wall members which are separately hinged to said front region of said housing whereby said wall members may be pivoted away from each other to open said housing for installation and removal of said cylinders.

A movable cart for supporting and transporting pressurized gas cylinders comprising:

• a closed housing having a floor, a front wall, opposite site side walls, a rear wall and a top wall forming a compartment of sufficient size to contain a pair of said gas cylinders in upright side by side positions, a first portion of said walls being joined to another portion of said walls by hinges to enable opening of said housing;
• first and second wheels journaled to said housing, said first and second wheels being disposed at opposite side regions of said housing adjacent the base of said front wall thereof and being positioned to extend forward from said base of said front wall and to extend upward from the plane of said floor at locations which cause said housing to be raised from the underlying surface and to be supported by said first and second wheels when said housing is tilted into an inclined orientation and which cause said housing to rest on said underlying surface when said housing is shifted to a more upright orientation;
• at least one pivotable leg disposed adjacent said front wall of said housing, said leg having an upper end that is pivoted to said housing and a lower end that may be pivoted outward from said front wall of said housing;
• means for selectively holding said leg at the outwardly pivoted position of the leg;
• a third wheel coupled to said lower end of said leg and being swivelable relative thereto;
• a plurality of gas outlet fittings secured to said housing and being accessible from outside said housing;
• a cylinder selector valve secured to said housing and having a manually operable valve setting selector that is accessible from outside said housing;
• and
• means for transmitting gas from a selected one of said gas cylinders to said outlet fittings in response to actuation of said valve setting selector.
