Preliminary heating apparatus for torch lamp

Abstract

A torch lamp having a fuel container, an evaporation section and a handle for supporting the container. A spouting body is attached to the fuel pouring hole in the container. The spouting body is provided with an ignition device and an adjusting valve. A supply pipe extends from the spouting body into the container.

Description

Claims

1. Torch lamp comprising a fuel container for receiving fuel therein, evaporation means mounted on the outside of said fuel container and receiving fuel from said fuel container, a fuel valve connected to said evaporation means for controlling the fuel passing through said evaporation means, a compressor mounted on the outside of said fuel container for supplying compressed air to said fuel container, whereby compressed air in said fuel container is operable to force the fuel in said fuel container out through said evaporation means, said compressor having an elongated section functioning as a handle for handling the torch, a pouring hole in said fuel container for supplying fuel to said fuel container, preliminary heating means removably mounted in said pouring hole, said preliminary heating means being positioned for heating said evaporating means prior to operating the lamp to evaporate fuel, said preliminary heating means comprising a body disposed in said pouring hole, a supply pipe connected at one end to said body and extending downwardly therefrom into said fuel container, said supply pipe having at least one bottom orifice opening into the inside of said fuel container for receiving fuel from the inside of said fuel container and at least one upper orifice opening into the inside of said fuel container for receiving compressed air from the inside of said fuel container, said preliminary heating means further comprising an adjusting valve for regulating fuel and air through said supply pipe, a spouting pipe connected to said body and having an opening adjacent to said evaporation means so that when said adjusting valve is opened, fuel under pressure flows from said bottom orifice located in said fuel container and compressed air under pressure flows from said upper orifice located in said fuel container into said supply pipe to said body and thence through said open adjusting valve to exit through said spouting pipe, and ignition means mounted on said body for igniting the fuel at the spouting pipe such that burning fuel from said spouting pipe thereby heats the evaporating means until the evaporating means is sufficiently heated to support combustion of fuel supplied by way of said fuel valve.
