Feb. 20, 1951 I. H. BORING PRESSING IRON Filed NOV. 15, 1946 IJ'AAC H. BORING Patented Feb. 20, 1951 UNITED STATES PATENT OFFICE PRESSING IRON Isaac Hartsell Boring, Maryville, Tenn. Application November 15, 1946, Serial No. 709,931 2 Claims. (01. 38-77) This invention relates to a pressing iron more particularly to a small electric pressing iron which can be usedwith or without steam depending upon the desire of the operator.

It is an object of the present invention to. provide a pressing iron which is of simple construction, which can be used with steam or at the Will of the operator can be operated without steam, and wherein the tank for containing the water which is used to supply the steam generating compartment is located in the handle of the iron removed from the basethereof so that the base of the iron need not be of large dimension to contain a water supply chamber.

It is another object of the invention to provide a combined steam iron and supply tank therefor within the handle, whereby the handle will be kept cool at all times, and wherein there is space provided above the heated base to which air can pass to keep the air which is heated by the top of the base of the iron from coming into contact with the hand rested over the handle and whereby the operator will not be subjected to the high heat of the iron.

It is another object of the invention to provide on the handle a control valve for controlling the flow of water from the handle to the steam chamber in the iron base so that While the operator is using the iron he may at any time cause the iron to generate steam while the same is in use and without the necessity of stopping the motion of .the iron over the cloth and wherein there is provided a control means so that the heat generated in the iron by the electric heat ing unit can be easily regulated to the different degrees of heat depending on the types of cloth being ironed.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevational view of the fiatiron embodying the features of the present invention.

Figure 2 is a longitudinal cross sectional view of the flatiron shown in Figure 1.

Figure 3 is a top plan view of the flatiron shown in Figure 1.

Figure 4 is an enlarged fragmentary end elevational view of the handle and showing in elevation the control valve accessible to the thumb of the operator while the press is being used to at his will deposit steam upon the cloth being ironed as in cases Where this may seem beneficial.

Figure 5 is a longitudinal cross sectional view of the iron base, and of one of the parts thereof but also showing another part in full.

Figure 6 is a cross sectional view of the upper part while showing the bottom part of the iron base in full.

Figure 7 is a bottom plan View of the iron base with the opening therein through which the steam is dispensed.

Figure 8 is a detail view of the bottom part of the base and looking upon the top thereof.

Referring now to the figures, [5 represents an iron base comprising a bottom part It and a top part IT. The bottom part [6 has an opening l8 therein through which steam is dispensed upon the piece of cloth being ironed at times: when the operator so desires that steam is needed. The bottom part [6 is of the usual press shape and has an upstanding flange IQ for providing a chamber divided into three

compartments

2i, 22 and 23. These three compartments are ob tained by providing walls or partitions 2d and 25. The compartment 22 is in alignment with the opening 18 of the base bottom part Hi and through which the steam is dispensed. The

partition 24 does not extend upwardly to the same height as the partition 25 thereby to provide an opening 28 between the upper edge of the partition and the bottom face 2? of the top part ll of the iron base.

The part H has extending downwardly from its bottom face 2! a hollow projection 23 having a chamber 23 therein and from which steam generated can be dispensed into the compartment 2! through an opening 3|.

In the compartment 23 there is disposed an electric switching device 32 supplied with electric current by a cable 33. Extending upwardly through the top part i! is a shaft 34 adapted to be operated by a lever arm 35 whereby to regulate the current supply delivered to heating coil units 36 which are contained on the bottom part it around the upstanding flange l 9. As best shown in Figure 8, the heating coil 36 extends substantially entirely about the flange l9, and the opposite ends of the heating coil are connected with terminal screws 31', mounted upon the rear side of the flange !9 andspaced transversely apart, as shown. A continuous elongated pad 36' of asbestos or the like may be arranged between the heating coil 36 and flange It. In order. to enclose the heating coil units 36 a sheet metal strap 3! may be extended around the peripheries of the top part I! and a shoulder 38 on the bottom part I6. This strap 3'! is retained in place by a screw 39. The parts l6 and l! may be detachably secured together by an elongated horizontally disposed screw 4|, extending through a depending projection of boss 42, formed upon the bot- Vertically spaced from the top part ll isa horizontally-disposed flat plate 44. The connection of the plate 44 is effected by long screws 45 extending through spacing sleeves 4-5. This arrangement will provide an open horizontally-disposed breezeway 41 so as to permit the top of the iron to be cooled as when air is passed laterally through the space '4]. Thus, as the iron is moved back and iiorth over the article being pressed, at free passage of air is achieved through the breezeway 4-1 to cool the :upper portion of the base and likewiseprevent the plate 44 from becoming overheated. The plate 44 will accordingly insulate "the iron base from a handle 48.

The handle 48 is in the form of a cylindrical tank adapted to contain the water used for effooting the generation of steam. The operator will grasp the handle 48 and inasmuch as there is water within the same the handle will be kept cool, and since there is provided a plate 44 by which aventilating space 41 is obtained the space around the handle through which the hand is extended should be kept to a minimum temperature and such that the operator need not be made uncomfortable by the heatupon his hands.

, The handle 48 is supported on vertical supports and 52 carried-on the top of the plate 44. Extending downwardly through the vertical support 5| is a tube 53 for conducting water from the tank 48 to the chamber 29. This tube passes downwardly through the plate M, the space 41 and through the top part ll into the chamber.

'The upper end of the tube 53 is supplied with a valve seat 5% with which cooperates a needle valve 55 extending upwardly through the tank and to the top thereof. Pivotally connected with the top of the needle valve 551s an operating lever 58, accessible to the thumb of the operator at one side of the handle. The lever 56 ispivotall-y mounted upon an upturned L-shaped bracket 57, rigidly secured to the top of the tank or handle in The lower end of the lever 56 is inwardly bent, as indicated at 58, to enter a small opening "59 in the vertical support 5i The lever 56 is free to swing in a vertical plane toward and away from the handle or tank 48, as shown in Figure 4, for causing the needle valve 55 to reciprocate vertically. In this manner the needle valve is raised and lowered from the valve seat 54, to permit water to be introduced into the tube '53. When the lever 56 is pressed inwardly toward the handle 48 the needle valve 55 will be raised from the seat 54, and when the lever '56 is released, the needle valve will return by gravity to the seat 54. The tank may be filled with water through a filler plug opening in the top of the tank and at the rear thereof, as shown at 51 Having now described my invention, I claim; 1. A. steam pressing iron comprising a bottom pressing plate having a steam discharge opening a formed therein, an upstanding substantially continuous flange formed on the top of the pressing plate and arranged inwardly of the marginal.
