Application filed Kay 14, 1926. Serial No. 109,019.

, The invention relates to s ring. ironing pads as employed in ironing tables for pressing or in rolls of ironing machines, for example, pads of the type consisting substan- .5 tially of a base plate upon which are secured-a plurality of adjacent and helically coiled springs, the latter being covered by suitable caps or the like which support a fabric top com osed of one or more layers of suitable pa din material. In aprior application for U. Letters Patent filed by me the last day of May, 1923, Serial No. 635,853, I have disclosed a substitute for a large portion of the fabric padding generall5 ly employed, in that there is interposed bel tween the spring caps or springs themselves individual locks of more or less resilient material of a heat insulating nature. The arrangement set forth therein ihvolves the '20 use of a metallic cap fitting over the outer or free end of a spring to cover'the same and a second metal cap secured to or formed integrally with the first named cap for retaining and supporting the block of heat in sulation material fitted snugly therein.

I have found it ssible, however, with respect to the insu ating material substituted to eliminate this double cap and receptacle member while retaining the advantages of the intermediate resilient blocks of heat insulation material; and the present invention has for its object a cappmg member for the free end of the spring, and, also, to dispense entirely with the use of cap members of the aforesaid character and to employ merely a disk which is suitably formed to admit of its being removably secured to a spring end. When intended for use with.

insulation material, the coil disk is provided, also, with means for attaching and holding thereto a block of the heat insulating material in manner such as to be insured against dislodgment. A further object of the invention resides in a construction of 4 capping member which is of itself not only more readily and inexpensively manufactured, but in its use generally facilitates the assembly of the pad. A still further object resides in the novel arrangement as ap- 60 plied to rolls, whereby through the use of the novel disk members it becomes possible to hold in position and prevent from slipping the coverinfikmaterial or first layer of the padding for e blocks.

To this end, the invention comprises a novel disk mmber provided with integral springs 11; and, for example, two forms of and resilient means of attachment to the spring ends and from which may be struck up suitable holding portions for attaching to said disk a block of heat insulating material or for holding the covering material against slipping, or both.

"The nature of theinvention, however; will best be understood when,described in connection with the accompanying drawings, in which:

Figure 1 is a fragmentary detail view, partly in section, illustrating a plurality of springs and the novelmeans for supporting the fabric adding or covering of an ironing pad with intermediate heat insulating material.

Figure 2 is a similar view illustrating a modification.

Figure 3 is a perspective view of the novel disk member as constructed for retaining a block of heat insulation material.

Figure 4 is a vertical section of a disk with block of insulation material held thereby.

' 'Figure 5 is a fragmentary plan view of a portion of an ironing roll with a section of the fabric covering removed and showing also the novel manner of holding in position, and preventing from slipping, the covering material.

' Figure 6 is an enlarged fragmentary .transverse section through the pad shown in Figure 5. I Fi e 7 is a fra entary section of a simp 'fied form of t e pad supporting or capping member for the spring ends, and Fi re 8 is a plan view of the modified mem r.

-Referring to the drawings, the ironing pad may be of various shapes to suit, for

example ironing machines ofthe roll type,

Figures 5 and 6, and embodies a base plate 10 upon which is mounted a plurality of ad jacently disposed resilient members as the coil springs 11 with convolutions reduced in diameter at both ends, Figure 1, or only at the base end, Figure 2. These resilient members may be secured in any suitable manner to the base late; and at their tops receive the novel di member 12, more particularly shownin Figures 3, 4, 7 and 8 of the drawings. These disk members 12, in accordance with the invention, are so constructed astobereadily attachableto and removable from the tops of the respectlve the disk member may be employed to accommodate and provide for adequate attachmentto the two types of springs, namely, the conical free ended Spring, Figure 1,

and the full diameter end, Figure 2, of the drawings.

To this end, the novel capping member is constructed as shown of a circular disk of metal 12 which, when intended for use with heat insulation material, may be stamped out with a plurality of fins or projections 13 extending from its circumferonce, or edge in the case of a rectangular or other straight sided type, which rim portions are then turned upwardly at the edge of the disk to form a shallow dish-like member to receive and secure a block of heat insulation material 14; against becoming dislodged laterally. The blocks 14 may be of cork, leather, asbestos or composition of a more or less resilient and heat resisting nature, and are designed to be further held in position by spurs 15, preferably two, and which are struck upwardly from the disk. These spurs are pointed at their free ends to allow ready insertion of a block thereover, and will serve to further hold said block sufliciently to prevent its dislodgment. In the useof two or more of the spurs located eccentrically, rotational movement of a block is provided against; and in the manufacture of the disk, the said spurs 15 may be barbed, as indicated, to insure against too ready withdrawal of a block from a disk.

Also, in forming up the sides or holding flanges 13 of a disk, the intermediate portions left thereby are designed to be turned downwardly and under the disk with a more or less doubling of a portion thereof upon itself. This forms a plurality of curved spring fingers 16 adapted to fit within a free spring end to receive the same and be held under a slight spring pressure to the uppermost convolution of said end of a spring. In the event that full diameter free end springs are employed, as indicated in Figure 2 of the drawings, the rim portions left after striking up the projections 11 are not turned under to the extent required in thecase of the taperedoff spring ends, but are spread sufficiently to fit over the outside of the convolutions, as shown in Figure 2, rather than within the convolutions as in the embodiment illustrated in Figure 1.

The particular construction set forth lends itself also to the prevention of slipp ng of a superposed'covering strip of padding 20, Figures'5 and 6, in that certain of the spurs 15, for example those of a number of rows along the entire length of the roll near the edge of the material, may be of length sufficient to project a slight distance above the tops of the corresponding blocks '14 and pierce the material 20. If this end of the covering material should then eventually wear sufficiently to no longer be properly held thereby, it would be necessary merely to cut off a short length and then replace the strip over the protruding spurs. By the foregoing expedient, longer life of the padding material is insured and all danger of slipping and bunching thereof obviated.

\Vhen it is not desired to utilize an intermediate layer of heat insulating material, the simplified form of caping disk, illustrated in Figures 7 and 8, maybe employed. As shown, only the downwardly-turned spring fingers 16 are thenprovided integrally with the bod i of the disk as the upper projections or flange members 13 are not required. The upstanding spurs 15, however, may be retained for holding of the. padding material, but will be somewhat shorter; and it is preferred, furthermore, to provide the disk with perforations 21 for draining the pad of moisture.
