2 Claims. (oi. 88 137) My invention relates to ironing table tops and has for, its object to provide a wooden ironing table top of novel construction which'shall be light and strong and wherein the heat from the iron when used in ironing, will be largely retained in the portion of'the table top which is adjacent the iron.

The construction of ironing table tops generally employed at the present time embodies a solid board, usually a sheet of lumber of suitable thickness and shape supported by suitable legs. common operation the table top is provided with some kind of a cover pad over its surface and the ironing is effected in the usual way by means of an electrically heated flat iron, generally'referred to as an electric iron. The heat from the iron passes throughthe protective covering intothe substance of the wooden top and in time may produce cracking and warping, and, where the board is of suflicient thickness to give requisite 3.

. Fig. 6 is a sectional view these advantageous results are obtained are particularly pointed out in the claims.

In the drawing:

Fig. l is a top plan view of my ironing table top with the position of the skeleton framework indicated in dotted lines;

Fig. 2 is an edge-view of what is shown in Fig. l.

Fig. 3 is a plan'view of the skeleton framework of the ironing table top before the enclosing sheets have been applied thereto.

Fig. 4 is a very much enlarged transverse sectional view taken on line 44 of Fig. l..-

; Fig. 5 is a similarly enlarged longitudinal view taken on line of Fig. l.v

of a modification of the enclosing sheets.

As shown in Fig. 3, a'skeleton framework of a- 'table' topembodies longitudinal ribs It spaced apart so as to leave longitudinal channel spaces it between them, whichiribs it are secured at their rear ends to a rear block i2. Two obliquely invention to obviate these disadvantages by providing an ironing table top which will be much lighter than the solid wooden tops heretofore employed which latter will tend to warp or crack,

and which will have the advantage of retaining Y the heat from the iron in its top portion where it is available to aid in the ironing action. It is therefore, an object of my invention in carrying out the above designated purpose, to provide an ironing table top which comprises a multiplicity of supporting ribs, preferably of wood formed into a skeleton framework outlining the shape of the ironing table top, in combination with ply wood or other specially constructed sheets applied to thetop and bottom surfaces of said skeleton framework whereby a cellular structure is obtained which is at the same time very strong and relatively very light, and which embodies extensive spaces .between the top and bottom sheets.

It is a further object-of my invention to form on thefacing surfaces of the sheets which enclose the aforesaid spaces, a layer of some heat way and the heat from the iron will be retained in the top sheet.

Other objects and-advantagesof my invention I will appear in connection with the detailed deframework, setsof enclosed spaces it which bedisposed ribs l3 and N are united at their rear ends to outside ribs. I 5 and i6 and extend obliquely to the ribs it to a curvedfront piece If to which the oblique pieces i3 and It and some of the longitudinal ribs iii are united, others of the longitudinal ribs It being united with the oblique pieces 13 and It, all as clearly shown in Fig. 3.

"There is thus provided a supporting framework which is rigidly united together and which forms,

when top and bottomsheets are applied to the come in efiect dead air cells within the body of the ironing table top.

Blocks it placed as shown between pairs of the ribs it somewhat stifien the central portion of the ironing table top transversely. Upon'the cellular-skeleton framework, as shown in Fig. 3, a t'op sheet It and'a bottom sheet 2b are applied,

being secured to the outer surfaces of the ribs i0, i3, if, it and It, the end blockslZ and I1 and the blocks it by any desirable means, but

preferably some strong water proof glue. The sheets is and 20 will be quite thin and light, preferably beingformed of plywood. Three ply plywood 'is shownin Figs. 4 and 5 and I have found this to bever'y' satisfactory for the purpose. This is a standard and well known article of commerce embodying a central ply or layer of wood 2! and outside plies or

layers

22 and 23 with the grain ofthe wood of the several plies in crossing relation oneto the other.

.To the inner sides of the top ply wood sheet scription thereof and the novel features whereby it, I apply 'a layer f l'of some material adapted the lower enclosing sheet .20. The cellular spaces II are therefore, provided with facing whereby the heat transmitted through the top layers of this heat ray reflecting material. It 7 follows that whatever heat may be transmitted through the sheet is into the cellular spaces ll under the hot electric iron, will have its rays reflected back from the surfaces 25 of lower sheet 20. The cellular spaces II will therefore not be too substantially warmed and but little heat will be transmitted through the entire table top but most of the heat will be retained in the top layer or sheet N; v

Another form of material for the top and bottom sheets I! and I! isshown in Fig. 8, wherein retained in this top portion or sheet where it is available as an aidto the ironing operation.

I claim: a

1. An ironing table top comprising a skeleton framework formed of. longitudinal members spaced apart and secured at their ends, and.

relatively thin top and bottom sheets secured to opposite sides of said framework so as to provide a multiplicity of enclosed cellular spaces a sheet of wood 26 has layers of

paper

21 and 28 applied thereto with a layer of metallic foil or paint 29 applied to the outside of the layer of paper 28. v a

The advantages of my invention will be apparent from the foregoing description. A primary advantage is that an ironing table top is provided which at once is both very light and very strong and wherein the ironing surface is peculiarly adapted to meet the conditions requisite for an effective and satisfactory ironing operation. This advantage is combined with and very much multiplied by reason of the fact 30 that the structure embodies a multiplicity of sealed cellular spaces the fronting walls of which are covered with layers of heat ray reflecting material such as'metallic foil or metallic paint,

within the body of theironing table top, said sheets being covered with a layer of heat ray reflecting material on their surfaces towards said cellular spaces. v

2. An ironing table top comprising a shaped board having top and bottom portions, front and rear transverse end members secured to each thereof, a. series of frame members entirely around the rim of the board extending between the front and rear end members, a series of longitudinal members extending between the rear transverse member and the front members or the rim members to form a set of large spaces extending between the inner surfaces of the top and bottom members, and a layer of metallic foil on each of said inner surfaces forming limiting walls of said spaces whereby heat rays passing through the top wall from the electric iron when the ironing table top is in use will be reflected in said spaces and the heat retained in the top wall.
