Application led July 21, 1928,Seria1 No. 652,990. Renewed April 25, 1027.

Theobject of my invention is to provide a durable, resilient pad which will he capable of repeated use without damaging'l any garments which are pressed thereon and which will permit the passage of steam or other vapor or air therethrough at any and all times. This and other objects are accomplished by my invention, some embodiments of which are hereinafter more particularly set forth. f

For a more detailed description of my invention, reference is to be had to theaccompanying drawings, forming a part hereof. in which Figure 1 is a plan view of a padembodying my invention.

'Figure 2 is a sectional view taken on the line 2--2 of Figure 1.

Figure 3 is similar to Figure 2. except that it is smaller and the pads are shown under compression.

Figure 4 is taken on the line 4--4 of Figure 1, looking in the direction of the arrows, except that the pads are shown slightly separated instead of one resting on the other.

Figure 5 is an end elevation of a roller provided with a pad embodying my invention. 'i

Figure 6 shows one form of pad suitable for aroller of the type and kind shown in Figure 5.

Figure 7 is an edge view of the pad shov/n in Figure 6, and

Figure 8 is a plan view of a covering for the springs.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My improved pad 1 in the embodiment shown in Figures 1 to 4 inclusive is composed o two elements each of which is a pad,I one being designated by the character 2 and the other by the character 3. The pad 2 is covered by two layers ot gauze 4 and the pad 3 by a single layer 5. These layers may be secured in any suitable way as by folding over. as shown in Figure 4.

Each element of my pad is provided with springs 6 composed of a sheet of a hard drawn brass 7 which has a series of tongues 8 and 9 struck up therefrom; the tongues 8 `standing' in one direction and the tongues 9 in the other, and these tongues are so arranged and disposed that the rows alternate so that the tongues 8 will be adjacent to the tongues 9 on each side and the tongues 9 will be ad]acent to the tongues 8 on each side.

When these tongues are made they are preferably formed with free ends which are curved downwardly, as indicated at 10, so that under no circumstances will they dig into or injure wire fabrics 4 and 5 While functioning.

When the pad 1 is put under compression. as shown in Figure 3, the two elements 2 and 3 are evenly compressed because they are of substantial even strength s o that 'if the pad 1 is compressed a distance say of one quarter ot an inch. each element is compressed onehalf this much. If more than two layers are employed, the depression of each layer will vary inversely with the number employed, as is obvious. When each tongue is compressed, it is somewhat flexed, but all the bending does not occur in any tongue because the stresses are transmitted through the tongue to the body of the sheet 7 which is correspondingly bent; that is for example, if a tongue 8 be compressed at 11 the sheet 7 will be elevated slightly at 12 so that the stresses are well distributed throughout the entire spring 6 and all wear and tear is not concentrated at any point.

In the embodiment of my invention shown in Figures 5 to 8 inclusive, the structure is modified so that it may be applied to a roller 13 such as a heavy roller in a mangle or other ironing machine which is driven through its axle 14 in the conventional manner. This roller has a coarse spring 15 of the type shown in Figures 1 to 4 inclusive and this goes entirely round the circumference once and then the samesheet is cut with smaller springs 16 of the same identical type which a're-so small that the tongues 8 and 9 of the large spring cannot go through the openings from which the smaller springs are sprung and these small springs are continued through 360 degrees and rest over the large springs and then secured to one end of the small springs as at 17 is a covering which may be a weaving 'of ratan or similar substance 18 with its wire mesh 19 resting thereon and this extends through 360 degrees and completely covers the fine springs 16 and then secured to the end of the wire on top of this ratan and resting thereonis the cloth 2O which may be placed in one or two layers, as desired. The cloth is preferably canvas or duck, such as is usually used for covering rollers. The s ring cushion, ratan, and cloth are laid-so that as the roller runs l whatseparated. Of course this does not occur inpractice where the' parts cooperate in such a manner that a smooth, cylindrical surface results, thesprings compresslng at the point of starting in 'such a manner that this result is obtained.

In Figure 8 is shown a substitute for the wire and ratan, the parts 18 and '19. This substitute 21 is composed of sheet brass, the same as the .coarse and line springs, except that it is slotted with long rectangular slots 22 which are so arranged and disposed that the center of one slot is opposite the ends of adjacent slots. These slots are so narrow that the tongues of the-springs 16 cannot pass through` them. f

.When the pad shown in Figure 5 is used, steam can readily pass through the pad one way or the other because there is nothingto stop it and the pad may give at any olnt so as to permit a button, or other artic e on the laundry to press against the pad and pass Without detriment or injury and as soon as this depressing influence is removed, the pad assumes its normal shape and furthermore, this padis capable of a very great compression because of its two layers. It is also obvious that this pad may be readily applied by securing one end of the larger spring at 23 to the face of the roller, as by soldering or otherwise, as desired, and then the roller is run and the pad wrapped around it with the result that it wraps true if it is started right and is ready for immediate use. When used the cloth will from time to time wear out and will have to be replaced while the remainder of the pad remains intact for an indeinite time.

1While I have shown and described some embodiments of my invention, it is obvious that it is not restricted thereto, but that it is broad enough to cover all structures that' come within the scope of the annexed claims. 5f,

row standing in one direction and those in an adjacent row standing in the opposite direction and a covering means for said spring element. v c

2.- In a device of the class descrbedya spring 'element composed of a sheet metal base with tongues cut therefrom, said tongues being'struc'k up in a series of rows, the tongues in each row standing in one direction and the tongues in adjacent rows standing in the opposite direction. y

3. In a pad of the class described, a sprin element composed of spring tongues strucg from a sheet metal base, said tongues being arranged in rows with ythe tongues in each row standing in the same direction and in the opposite direction from the direction in which the tongues stand in adjacent rows,

said tongues having downwardly curved free enls and a flexible cover for such curved en s.

4. A ad for a roller, the pad being comsof posed o two layers of spring fabric, the inner layer having spring tongues struck therefrom which are larger than the spring tongues struck from the outerl layerand a suitable covering for said springs.

5.. In a pad of the class described, a spring element composed of spring tongues struck from a sheet metal base said tongues having downwardly curved ends adapted to engage a exible cover.

6. In a pad of the class described, a sprin element composed of spring tongues struc from a sheet metal base in parallel rows, said tongues having downwardly curved free ends adapted to engage a cover.

In testimony whereof, I have hereunto set my hand this 27th day of June, 1923.
