IRONING BOARD Filed Feb. 20. 1933 Patented Feb.- 20, 1934 UNITED s'rA'rlzs APanam' OFFICE ZCIaims.
My object is to provide a simple, inexpensive and durable improvement in ironing boards, including a thin metal sheet on top of an ordinary ironing board.
Another object is to so mount the metal sheet Athat it will be ilxed to the ironing board in a manner that will not permit the metal sheet to buckle.
A further purpose is to arrange the metal sheet within the outline of the board, so that it will not buckle against a pad or the like arranged above the metal sheet and secured to the board.
It is my object to provide a sheet of metal which can be quickly heated, which will absorb some but not too much heat,'and which will reflect heat, to accomplish the desired results hereinafter referred to. l
Another object is to provide such a device with heat insulating material below the reflecting sheet.
Another object is to provide such a board together with a thin cloth covered metal sheet, adapted to be placed over a collar or a part or all of some article to be ironed, in such manner that the user may run the at iron over the second sheet for ironing the article between the sheets.
With these and other objects in view, my in` vention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully. set forth, pointedv outein my claims, and illustrated in the accompanying drawing,'in which:
Figure 1 is a perspective view of an ironing board equipped with a metal sheet and embodyingA my invention.
Figure 2 is a transverse, sectional view taken on the line 2---2l of Figure 1.
Figure 3 is a vertical sectional view through a second sheet to be attached for ironing collars and the like. In the accompanying drawing, I have used the reference numeral 10 to indicate generally an ordinary wooden ironing board supported by the usual foldable legs 11 and 12, and braces 13.
On the top of the ironing board, I place a thin l the board, so that it will not expand to the edges l thereof when heated.
An ordinary cloth pad 16 may be placed over the sheet 14 and fastened to the board 10 in any suitable way.
It will be understood that any means adaptable for the purpose may be used for securing the refleeting sheet 14 to the ironing board 10.
I have found by extensive tests that the ordinary ironing board absorbs a great deal of heat from the fiat iron. By using the reflecting sheet 14, experiments showv that much of the heat is l reflected upwardly instead of being absorbed into the board 10. At first the reecting sheet 14 absorbs some heat, but at all times, it reflects much of the heat. f
.By using a reflecting sheet of this kind, I nd that that the amount oi electric current necessary to keep the flat iron hot enough for satisfactory ironing is substantially reduced. Reduction in current amounts to as much as in the neighborhood oi 25%. This is true because heat ordinarily absorbed into or passing into the lwooden board is reected upwardly and is not lost where my reflecting sheet is used. Furthermore on account of the fact thatA the reecting sheet` the garment receives heat'from below as well as from above, and a better gloss is obtained.
Similarly, I find that there is secured with this reflecting sheet a better gloss on ordinary white garments.
The sheet 14 should be quite thin, so it will not absorb too much heat and to reduce expense. The character of the metal and the thickness may be varied to some extent.
Preferably insulating material 19, for instance an asbestos sheet,is placed underneath the reflecting sheet 14. This serves to hold the heat in the reflecting sheet and to prevent-passage of heat to the wooden board, and still further contributes to the economy of the electric' current. This heat insulating or non-heat conducting material `may be in any form and Vof varying thickness as may be desired, and may be fastened tothe wooden board or to the reiiecting sheet or may be simply placed in position as. an independcnt unit. It makes it' pessime to reduce me thickness or the sheet 14 to a mum.
The dlculty of ironing some articles, for ingstance, collars, is Well known. I preferably provide for use with my board a. thin small sheet A of metal 17, covered by cloth, canvas or the like 18, so as to be quite smooth. li preferably provide the sheet 17 with a iexible handle or the like 19 for convenience in handling it when hot. This sheet A can be placed overa collar or the like, laid out on the ironing board without wrinkies, and the at iron then run over the slceetv A for ironing the coller between the two heated surfaces and assuring 'the absence of wries. Especially if the sheet A is rst heamd, this method gives an excellent finish to starched articles.
I claim as my invention:
2. In a structure of the class described, a supporting element, a thin metal heat reectingsheet on the supporting element wholly within the outline thereof, a. pad outside the sheet and extendingr over the edges thereof and secured to the supporting element.
