Description: |
| Abstract:
A portable gas forge. The forge is comprised of a housing having an insulated interior and an opening for insertion of the article to be heated such as a horseshoe or the like. The forge is resistant to blow-out by wind when used in the field and has a specially designed burner connected to the top of the housing. The burner is connected to a source of gas such as an LP gas cylinder. A gas orifice is connected to an enlarged burner pipe having a bell-shaped primary air inlet adjacent the gas orifice. A source of secondary air is located at the exterior pipe connection to the housing to provide an annular air passage through the housing to the burner outlet to obtain maximum flame concentration in the housing and inhibit burn back or back flaming. An internal restrictor adjacent the burner pipe outlet is employed to increase the burner gas velocity and aid in secondary air aspiration and combustion efficiency. A door is hinged at the bottom of the housing and may be opened to a horizontal position to provide a shelf support for the article to be heated. |
