Abstract

A portable open fireplace blowing appliance comprising a tubular body portion of a substantial length and uniform diameter formed of heat resistant material having a cap secured at one end, the cap having a centrally located opening between 1/32 of an inch to 3/32 of an inch through which a jet of air can be blown by placing the mouth at the other end, and a tapered mouth end of said body portion through which the user blows. By directing the blowing appliance to embers in a fireplace, the jet stream emerging from the cap opening causes the fireplace wood or charcoal to kindle and burst into flames.

Claims

1. A portable open fireplace blower comprising:

an open rigid straight line tubular body portion of substantial length and uniform diameter formed of heat resistant metal;

an end cap rivetedly secured at one end of said body portion having in a planar end section a centrally located orifice between 1/32 of an inch and 3/32 of an inch through which a jet of air is blown after placing the mouth of the user at the other end to blow, said cap having the same inside diameter as the outside diameter of said tubular body portion and the inside diameter of said tubular body being at least 6 times the diameter of said centrally located orifice;

a mouthpiece connector having an end opening whose inner diameter is substantially the same as that of said tubular body portion and is non-adhesively secured at the end of said body portion opposite said cap and orifice;

said mouthpiece connector including a tapered portion extending from the end of the tubular body and an end portion of substantially smaller diameter than said tubular body attached to the tapered portion;

a mouthpiece mounted on the end portion of said connector;

and said centrally located orifice being on the common central longitudinal axis of said body portion and said mouthpiece whereby a long column of air in said body portion under mouth pressure of the user exits as a fine single air jet along said common axis to permit accurate impingement of the air on a burning coal.
