Title of Invention

"GAS PRESS"

Abstract

Gas appliances are replacing or augmenting the electrical appliances at least in the areas like Kashmir valley, where there is a shortage of power supply. Proposed Gas Press is one such appliance which is expected to be greeted with a warm market welcome. It consists of an iron base with perforated steel hood having a non - conducting and non-melting handle fixed at its top. A steel tube torch drawing LPG gas from a cylinder and entering the press from the back side heats inner side of the base if it is lighted with the help of an electronic lighter or burning match stick, introduced through a hole made in the side of the hood. Enough air supply is allowed through the hood and the two holes made in the middle of the steel tube torch to ensure complete combustion of the gas producing a hot blue flame. The flame is prevented from rising up-wards (towards the hood) with the help of the double walled wire-gauze shell and a concrete slab insulates the hood. The concrete slab also adds to the weight of the press for efficient ironing.

Complete Specification "Gas Press" Introduction: Gas appliances are rapidly replacing or augmenting the electric appliances, particularly in the areas where there is dearth of electricity or power supply suffers from low voltage. So in the areas like Kashmir Valley we experience increasing use of gas geysers, gas heaters, gas stoves etc. Now we are trying to introduce a gas press for use of ironing the clothes or drying wet garments. Construction and working: The Gas press consists of a heavy weight iron or light weight base Fig.a (1) and Fig.c(l) having a stainless steel perforated hood Fig.a (2) (of about 4 inch height) on it with a non conducting and non melting handle fixed on it (3). The holes of the hood of about 3mm dia allow a free supply of air. into the press Fig.a(4). A steel tube torch Fig.a(5) Fig.c(5)having two big holes in the middle c (6) for air supply, fitted at its rear end with a nipple of the aperture equivalent to that of a gas light nipple c(7) and a nipple of very large aperture fitted at its front end c(8), enters into the press from the back side of the hood in a inclined position facing the iron base. The steel tube torch (5) has an on-off regulator for gas at its back end Fig.a(9)and is connected to a plastic or rubber pipe Fig.a(10) carrying gas supply from a gas cylinder, through a three way connecting link, so that, other appliances as gas stove etc. also work carrying gas form same cylinder. The regulator remains out side the hood of the press. There is also a big hole Fig.a(l 1) at the back of the hood for inserting a lighter or a burning match stick. An automatic electronic lighter can also be use working with regulator itself as used usually in gas lights. When gas is allowed to enter the torch (5) by opening the regulator (9) a very thin ray of gas under pressure goes in and it is ignited at front end large aperture nipple (8) by a lighter or a mach stick and a hot thin blue flame strikes the inner surface of the base(l). The flame spreads on the major portion of the base heating it considerably. The free air supply passing through holes (4) of the hood (2) and then through the air holes (6) in the torch (5) allows complete combustion of the gas at the base. To prevent the flame from rising upwards (towards the hood) there is a double walled wire - gauze shell Fog.c(12) on the base (1) just covering the flame area. To insulate the steel hood further it is fitted with a concrete slab Fig.b(13). The slab is covered with a tin foil which apart from reflecting heat towards the base prevents the pieces of concrete (if any) produced by breaking of the concrete due to excessive heating, from falling. The concrete slab also increases the weight of the press to make it effective for ironing the clothes. This is all about the structure and working of the gas press. Alternatively, to heat the base we can use a circular Fig.d,i(14) or U-shaped tubular heating element Fig.d,ii(15) having perforations on its sides in place of a front end large aperture nipple. When ignited the small tiny blue flames come out of the small perforations and heat the base. One more alternative heating element in place of front end large aperture nipple or porous tubular element, will be the traditional wire - gauze heating bulb Fig.d,iii(16) used in room heaters working on gas with a reflector (17)at its back facing the iron base of the press. We claim: 1. A "Gas Press" meant for ironing the clothes or drying wet clothes, working on combustible gases as LPG etc., consisting of a steel tube torch having a regulator and a small aperture nipple at its rear end, two air holes in the middle and a large aperture nipple or tubular porous heating element or wire gauze bulb at its front end which throws a flame on an iron heavy weight or light weight base, the flame being prevented from rising upwards by a double walled wire gauze shell and a heavy perforated concrete filled steel hood with an insulated handle forming the outer body and a plastic or rubber pipe drawing gas from gas cylinder to the steel tube torch.
