2 Claims.

The object of my invention is to provide a simple, durable and inexpensive buck of improved construction for ironing machines, and particularly of the type employing a cold buck plate 5 and a hot head plate. In this type of ironing machines considerable annoyance has been experienced due to the fact that clothes ironed thereby frequently become spotted due to the condensation of moisture in the padding from the L0 clothes as they are being ironed, the moisture causing a portion of the coloring matter in the padding-to be dissolved and carried to the garment being ironed, resulting in undesirable stain.

It is, therefore, the object of my inventionto iii-provide an improved buck plate so constructed that condensation of the moisture in the padding will be eliminated.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of my improved buck, showing the manner in which it is supported beneath the head plate. The mechanism for supporting the buck and head plate is eliminated inasmuch as it forms no part of this present invention.

its oo-acting head plate.

Referring to the accompanying drawing, the reference numeral indicates the buck plate, which is formed preferably of cast metal and of a shape to fit the under surface of the head plate 11. The upper surface of the buck plate 10 is preferably finished, said finished surface having one or more layers of heat insulating material 12, such as asbestos. The edges of the insulating material terminate with the edges of the buck plate 10.

, Covering the upper surface of the heat insulating material 12 is a moisture proof heat conducting member 13, preferably a sheet of steel. The edges of the member 13 are rolled over the edges of the heat insulator and under the edges of the buck plate 10, in the manner clearly illustrated in Figure 2. The member 13 is fitted snugly to the heat insulating material.

Supported above the plate 13 is a layer of padding 15 of ordinary construction and usually formed of flexible fibrous material. The entire padding is covered with a layer of cloth 16, having. itsedges folded under the edges of the mem- Figure 2 is a sectional view of the buck and hers 10 and 13, said edges being stitched in position in the usual manner. The cloth 16 supports the padding in place which may be removed, often as necessary. I g. n

The top surface of the padding 15 is preferably convex to fit the concave under surface of -the member 11.

The buck plate and head plate are provided with mechanism for separating the two members while placing the clothes in position to be ironed, and for bringing the two members together and applying pressure and heat to the head plate 11. This may be accomplished either through an electric heating unit or by means of a. heated fluid such as steam. The buck plate 10 is operated comparatively cold. 7

As soon as pressure has been applied to the members 10 and 11, and a damp garment to be ironed is placed between the said members, it will be seen that heat from the member 11 will turn the moisture into steam, at large portion of which will be forced downwardly into the padding 15 until after the head member 11 is removed. This steam will engage the member 13, which has been preferably heated by means of the member 11 and through the padding 15.

The upper surface of the insulating material will also be heated to a less degree, while the under surface of the insulating material will be at a temperature substantially equal to the temperature of the buck plate 10:

In actual operation the temperature of the member 13 is always maintained at such a degree that condensation of the steam in the padding 15 is prevented. The heat insulating material is designed to prevent cooling of the plate '13. The member 13 also prevents moisture from being absorbed by the heat insulating material as the said material is more effective when dry.

By forming the member 13 of heat conducting material such as steel or other metal, heat may be conducted longitudinally through the member 13 from one end of the padding to the other, if for any reason a large amount of moisture is being vaporized on one end of the padding while on the other end the padding is comparatively dry, thereby providing means whereby the comparatively heavy moisture portions will be supplied with heat fast enough to prevent condensation, and always maintain the padding in such condition that spotting is prevented.

I claim as my invention:-

1. In a device of the class described, a cold metallic buck plate adapted to co-operate with a heated head member, heat insulating material carried by the upper face of the buck plate, a

layer of moisture proof material having heat conducting properties covering said insulating material, a layer of fibrous padding over the outer surface of said moisture proof material, and means for binding all ofsaid members together, whereby the moisture proof heat conducting material will become heated by heatradiated or con ducted from the co-operating head member to evaporate any moisture engaging the same from material being pressed between said buck plate and the co-operating head member and at the same time prevent any of said moisture or steam from entering the heat insulating material.

2. In a device of the class described, a cold buck plate adapted to co-operate with a heated head member, heat insulating material carried by the upper face of the buck plate, a moisture proof sheet metal plate supported on the upper surface of said insulating material and having its ends folded over the ends of said heat insulating material and under the edges 'of said buck plate, a fibrous padding carried by said sheet metal plate, and a fibrous covering for said padding having its ends folded over the ends of said sheet metal plate, whereby the sheet metal plate will become heated by radiation or conduction from the cooperating heated hea'd member to evaporate any moisture engaging the plate from material being pressed between said buck plate and its cooperating head member and. at the same time prevent any of said moisture or steam from entering the heat insulating material.
