cured,- extendfromsideto side'of vrthe-bottomof 3 the board and are welded to the depending edge 4I) and the bottoms of the channels I3.

As previously pointed out, the reinforcing member II does not extend to the head of the table I0. It terminates along a line which is coincident with the section line 6-6 of Figure 1 to provide ve of the channels I3 with open ends through which the electrical heating elements are inserted. The heating elements comprise two lengths of Nichrome or other wire insulated with an asbestos cover. One length is designated a and the other b. The lengths are positioned side by side with their terminal ends adjacent each other. There is then formed in each wire a series oi ve loops or fingers I 'I which are tied at the open end as indicated at I8 or held by clips or other fastening means to form a harness I6 as shown in Figure 8. The lengths of the loops or fingers I'I correspond substantially with the lengths of the respective channels, I3 into which a respective loop is inserted. To install the harness it is only necessary to start each loop in the opening of its respective channel and then slide the whole harness into the position shown in Figure 1. In order to protect the wire from chaing at the openings of the channels i3, the edges of the channels at such openings may be rounded oi or there may be provided an end member I9 provided with a series of apertures located in alinement with the opening of each of the ve respective channels I3. In forming the apertures 2i), they are so pierced as to provide a turned-in bead 2I (illustrated in Figure 9) which provides a smooth and broad surface. The end member I 9 may be spot-welded or otherwise secured in place across the ends of the channels.

An enclosure pan or removable cover plate 22 holds the heat selector switch 3l), the sad-iron outlet 3I and the electric cord 32 for connecting the whole unit to the source of electric power. It also closes the openings to the channels i3 and cooperates with the underside of the ironing board to provide space for the bodies of such switch and outlet and for the various terminals and wire connections including portion of the heating elements between the ngers II. The pan 22 has a circular shaped edge to conform with the head of the ironing board. This edge has an upstanding rim 23 which nts within the depending edge 43. The rim 23 is provided with tabs 24 which engage the underside of the top to position the pan. Screws 25 hold the tabs to the edge li to detachably hold the pan. llhe pan 22 also has a straight edge provided with projections 26 which, in the assembled condition, are contained between the inverted channels I2 and rest on top of the cross member I5 to hold that end of the pan in position. The bottom of the pan 22 comprises Walls 2 and 28 which slope upwardly and outwardly from the at central portion of the bottom.

The slope of wall Z'Ivurges the elastic draw edge of any pad and cover set upwardly to prevent it from interfering with the operating member of the switch 30 .and the openings to the sad-iron outlet 3 I.

The selector switch 3i) is mounted within the pan 22 to the left of center, as viewed in Figure 3.v Its operating lever projects outwardly through the wall 2'I so that it may be easily accessible at the head of the ironing board. The switch 30 is a double pole two-throw switch of customary construction, but only three of the terminals are utilized as will be seen from the schematic drawing of Figure 10. An outlet 3l of customary design is positioned within the pan 22 on the opposite side from the switch 30. There is an opening in the wall 21 which receives the face of the outlet 3l so that the plug of the cord of an electric sad iron may be readily fitted in the outlet. An electric cord 32 enters the pan from the bottom, and is connected to the terminals of the socket 3I. This cord has the usual plug (not shown) which permits it to be connected with a source of electric power.

.As shown in the circuit diagram of Figure 10, one end of wire a and wire b are each secured to one terminal 33 (see Figure 5) of the outlet 3|. The other end of wire a is secured to terminal 34 of the switch 3U, and the other end of b is secured to the adjacent terminal 35. The movable blade of the switch 3i) is connected to the other terminal 36 of the outlet 3l) and hence through the cord 32 to the other side of the source of supply. The terminal 34 of switch 3B is electrically connected to terminal 31 of switch 3l). With these connections and with the cord 32 plugged into a standard source of electrical power, the switch 30 may disconnect both wires, connect wire a only, or connect wires a and bv in parallel with the power. When a and b are both connected, the maximum wattage is consumed and the board is heated at the selected high degree. When the wire a only is connected to the source of power, the wattage consumed is decreased and the board is heated at the selected low degree. The temperature of the board and any pad or cover set can thus be readily adjusted. In ironing some material it is preferable to have the board at the high degree while in ironing other material it is more desirable to have the board at the low degree.

The board is provided with a head stand 3B which protects the head of the board and the switch 33 when the board is stored. The stand 3B comprises a bridge member and two legs. The legs extend under the marginal edge All and project into respective inverted channels I2 to rest upon and be secured by screws 39 to the top of the cross member I5. The enclosure pan 22 is provided with slots 39 to accommodate the legs of the stand 38 when the pan is secured to the board.

In order to replace the heating elements, it is only necessary to remove the screws 25, permitting the pan 22 to be easily disengaged from the board, and withdraw the pan and the harness I5 from the board as a unit. When withdrawn it is easy to connect a new harness to exposed terminals in the pan. Thereupon the new harness (with pan connected) may be slid into the channels 53, the projections 26 placed into engagement with the cross member I5, and the edge 23 inserted within the margin 40 and secured in place by the screws 25.

Although only one embodiment of the invention is shown and described herein, it will be understood that this application is intended to cover such changes or modiiications as come within the spirit of the invention or scope of the following claims.

I claim:

l. An ironing board comprising a iiat top havn ing a head at one end, a longitudinally corrugated member secured to the under surface of said topto reinforce said board, said corrugations providing troughs adapted to receive fingers of a removable heater, said member terminating along a line spaced from said head to provide access the end of said corrugated member, said transw Verse member having holes in alinement with said open ends of said troughs and accommodating said ngers, said holes being provided with a bead-like margin to facilitate insertion and removal of said heater fingers.

3. An ironing board as claimed in claim 1 in which a cross member extends transversely across said corrugated member and is secured thereto to brace said board, said removable cover plate having tabs resting on said cross member to aid in holding said plate in position.
