ELMA P. KUPFER, OF LEONIA, NEW JERSEY.
FLAME-SHIELD FOR GAS-STOVES.
Application filed June 28, 1915.
To all whom it may concern Be it known that I, ELMA P. Kmernn, a citizen of the United States, residing at Leonia, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Flame-Shields for Gas-Stoves, of which the following is a full, clear, and exact specification.
This invention relates to gas stoves, and has for one of its objects to provide an improved form of flame shield for such stoves which will reduce the quantity of fuel or gas consumed and also save time in heating a vessel or container.
In the operation of the ordinary open gas stove, such as is illustrated in the accompanying drawings, a large proportion of the heat units are ineffective for heating a vessel placed over the burner by reason of the horizontally moving air currents between the burner and the bottom of the vessel, so that it requires a much longer time to heat the vessel to the desired temperature and consequently consumes a considerably larger quantity of gas than would be necessary if the flame were protected from such horizontal air currents.
It is the aim of this invention to provide a simple and inexpensive form of shield for this purpose which may be detachably fitted to any gas stove and the use of which will.
result in a large saving in the cost of operating the stove and also greatly reduce the time consumed for heating or cooking food, etc.
Another object is to provide a detachable flame shield which may be very easily placed in position or removed by simply taking off the grid above the burner and which cannot be easily displaced or turned over when once attached.
A further object is to provide a shield which allows the necessary lateral travel of the heat along the bottom of the vessel being heated and permits the required air circulation through said shield while at the same time protecting the flame from the air currents which interfere with and detract from the efficiency of the burner.
Other objects will appear as the description proceeds.
The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of Specification of Letters Patent.
Patented Oct. 12, 1915.
Serial No. 36,690.
this specification, and then more specifically defined in the claims at the end of the descr ption.
In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views :Figure l is a perspective view of a common type of gas stove, showing my improved flame shields applied to its two burners, and one of the grids removed to more clearly illustrate how the shields are put in place. Fig. 2 is a perspective view of one of the shields drawn to a larger scale, and Fig. 3 is a vertical section through the platform supporting the stove and the top plate and grid of the stove, to more clearly show how the shield rests upon said platform and extends up substantially to the plane of the bottom face of the grid.
The gas stove 1 illustrated in Fig. 1 is of a well known type and has a top plate 2 supported in horizontal position by legs 3 resting on a platform 4t which may be any suitable level surface. The top plate 2 is provided with openings 5 above each of the burners 6 for permitting the heat to reach a vessel which may be placed over said openings, and as is usually the case said openings are fitted with removable grids 7 supported in position substantially in the plane of the top plate by lugs 8. The gas is fed to the burners by a pipe 9 extending along the front of the stove and from which branch pipes 10 run to each burner.
My improved flame shield comprises a cylindrical metal tube 11 as most clearly shown in Fig. 2. Said tube is provided with a plurality of vertical slots 12, preferably three, extending upward from its lower edge a suitable distance to permit one of them to fit over the branch gas pipe 10 and the lower end of the shield to rest firmly upon the platform 4 on the-base level of the legs "of the stove. When the shield is in position, as illustrated in Fig. 8. its upper end reaches up substantially into the plane of the under surface of the grid 7 while its body portion surrounds the burner 6 and prevents the flame therefrom being blown to either side before it reaches the grid. Inasmuch as the shield terminates below the grid. suflicient space, namely the thickness of the grid, is left between the top end of the shield and the bottom of a vessel placed on the grid. to
permit the desired lateral travel of the heat along the bottom of the vessel and the required air circulation through the shield.
It will be noted that the shield extends down to and rests firmly on the platform 4 on the base level of the legs of the stove, so that there is no danger of said shield being displaced or knocked over, especially as the top of the shield is just below the grid and one of the slots 12 straddles the branch gas pipe.
The shield may be economically made of sheet metal as shown in Fig. 2, and may be easily and quickly attached to any stove not provided with a flame shield by simply taking oif the grid, as shown in Fig. 1 above the right hand burner, slipping the tubular shield down around the burner with one of the slots 12 straddling the branch gas pipe 10 until the bottom of said shield rests upon the platform a and then placing the grid back again in position as shown above the left hand burner in F ig. 1. The shield may be readily removed in a similar manner for cleaning or renewal.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A flame shield for gas stoves comprising a vertical tubular member to surround a burner and rest removably upon the base level of a stove independently of the stove and burner and extend up to the bottom of the grid of the stove, said tubular member having a slot extending upward from its bottom edge to fit around the gas pipe of he stove.
2. The combination with a gas stove having a burner, a gas supply pipe leading to the burner, and a removable grid arranged above the burner and resting directly upon the top of the stove, of a tubular flame shield removably fitted around the burner and terminating at its upper end just below the grid, the lower end of the shield extending below the burner and being supported independently of the stove and burner.
3. The combination with a gas stove having a burner, a gas supply pipe leading to the burner, and a removable grid above the burner, of a tubular flame shield removably fitted around the burner and having a slot entering at its lower end and fitting around the gas sup-ply pipe, said shield resting at its lower end upon the base level of the stove independently of the stove and burner and terminating at its upper end justbelow the grid.
4. The combination with a gas stove hav ing a top plate provided with openings, legs supporting said top plate on a suitable platform, burners arranged below said openings in the top plate and above the platform, gas supply pipes leading to the burners, and removable grids fitting said openings, of tubular flame shields surrounding the burners and having slots fitting over the gas supply pipes, said shields resting at their lower ends upon the platform independently of the stove and burner and terminating at their upper ends just below the grids.
In testimony whereof I have signed my name to this specification.
