A field-ready oven has reinforced telescoped side walls that extend and hold a base, shelf, tray support and cover spaced apart. A low air intake and a semipermeable membrane deliver air and vapor fuel to catalyst pads on the shelf. Radiant heat from exothermic reaction is diffused over a bottom of a tray. Hot gas circulates around the diffuser and tray with a chimney effect before exhausting. A lid on the cover lifts for access to the tray. A fuel container in the oven forces fuel through a capillary restriction to limit fuel flow. A spring in the container is released to start fuel flow.

There is provided a stand for a canned heat fuel cell wherein the stand has a side wall, an upper marginal edge and a lower marginal edge, the side wall being sized to be slightly larger than the fuel cell side wall, inwardly extending groove dividing the side wall into upper and lower portions with the upper portion having a height greater than the lower portion and also having a plurality of apertures to permit an air supply therethrough, grill bars for sheeting on the top of the side wall, the arrangement being such that the stand will sit on the upper marginal edge of the canned heat fuel cell. The arrangement provides an efficient means of using the fuel cell while preventing bums to the user and/or damage to the substrate surface.

A valve of resilient material incorporated into a filler cap of a fuel tank for a portable camping stove, lantern or the like constructed to detachably receive an inflating needle connected with an elongated flexible hose having a pump engaged with the other end thereof. The filler cap is employed in the usual manner to replenish the fuel supply and when it is desired to pressurize the fuel tank, it is only necessary to force the inflating needle into a normally closed passageway in the resilient body which forms the valve.

A CAMP STOVE HAVING SEPARATE BURNERS THAT RECEIVE FUEL FROM SEPARATE VAPORIZING TUBES, BUT WHERE ONE BURNER HEATS BOTH OF THE VAPORIZING TUBES, AND FURTHER HAVING A CONTROL AS BETWEEN TWO BURNERS THAT RECEIVE FUEL MIXTURE FROM THE SAME VAPORIZING TUBE SUCH THAT WHEN THE CONTROL IS CLOSED IT DIRECTS ALL OF THE MIXTURE TO THE SECOND BUT AS IT IS SHIFTED TO ADMIT FUEL MIXTURE TO THE SECOND BURNER IT ALSO THROTTLES THE FUEL MIXTURE PASSAGE TO THE FIRST BURNER SO THAT FUEL MIXTURE IS DIRECTED TO THE BURNERS IN APPROXIMATELY EQUAL QUANTITIES WHEN THE CONTROL IS FULLY SHIFTED.
