sraiNe-ranni'ive STRUCTURE.

Application filed December 9, 1927. Serial No. 238,762.

This invention relates to resilient or spring padding structures. r

Resilient or spring pressed pads have many uses, onesuch use being in ironing machines. 5 In such machines the ironing elements, as for instance the ironing rolls,have their outer ironing surfaces provided with resilient pads to permit the surface to give or be depressed by buttons, hooks, orother project-ions carried by the garments passing through the machine Thel invention has for its salient object to provide a resilientpad structure that is sirnplein construction and that can be easily and quickly applied to the ironing element of an ironing machine or to any other structure at a minimum of expense.

Another object of the invention is to prol vide/a resilient pad structure so constructed and arranged that the springs or resilient elements are firmly and securely held in position under tension. f

Further objects of the invention will'appear from the following specification taken in connection withthe drawings, which form a part of this application, and in which Fig. 1 is a plan view partly broken away of an ironing roll having a resilient pad structure constructed iny accordance with the invention; l

i. The invention briefly describedconsists/ofl 'aresilient'pad structure in which the ele,-

* .menttowliich the padis to be secured is providfedlwith a groove ,or groovesv and a pluralit .of springs are secured toithe outer surface :0 theelement bysrecuriiig means, such as links, disposed in the groove or grooves.4 The.

springs are covered by s itable sheeting or a covering 'of felt or other suitable material.

In theJ particular embodiments of the inven tion illustrated the resilient pad structure has been,shoWn in connection -with the ironingelements of an ironing machine'y but it should be understood that the structure is not limited to this particular use and may be used in many other ways. For instance, the springs used in' upholstering furniture could be secured in the manner/illustrated and hereinafter, described.

Further details ofq the invention will appear fr om the following description.

In Fig. L there is shown an ironing roll 10 )for use i an ironing machine. The roll consists of a metallic shell 11, the outer surface 0f which,las shown in Figs. 1 and 2, is pro-l vided with a spiral groove 15.l This groove extends spirallyaround the outer surface of the roll from' one end to the other thereof. -In the. form of the invention illustrated in Figs. 1 to 4. inclusive, a plurality 'of setsI of springs A, B, G,`D., etc. are secured to the outer surface of the roll'10. Each set comprises a pair of springs 1 6 and 17, prefer- Vably of the spiral type, the two springs 16 and 17 being integrally connected by a portion 18. These sets of springs may be formed by straightening out one convolution of the.

spring and bending the springs intovparallel Y' relation as shown in Fi 2.

rllhe-'end spring16o the lset A is secured p I' Iin position b means `of a mfe'mber 20 having one .end 21v ooped around the base of the spring 16 and `having its .other-,end bent laterally as\shown'at 22 in Fig. 2 and secured in an aperture 23 formed'in the shell 11 in any suitable manner, as by means of a vscrew 24.

is disposed in the groove 15.

`Itwill'be noted that the securing member 20 The sets of springs are 'connected/tbgether by means of links 25, theF ends -ofthe links being looped around the bases of the springs of successive .sets andthe links, as shown in Figs. 2'and 3, being disposed' in the groove 15.

After the sets of springs are connected by means of the links 25thes ring structure is wound around the roll an the links 25 are seated in the groove. The spring at the other end of the spring structure is then connected to the shell by means of a member similar to the securing member 2Q.

The spring structure can be stretched tightly around the roll as it is Wound thereon, thus securing the springs firmly and securely to the outer surface of the shell under tension.

After the springs have been secured in the manner above described or in the manner hereinafter set forth, a suitable covering of sheeting, felt or other suitable material is Wound tightly around the outer ends of the springs.

In the form ofthe invention shown in Fig.

f 5, the springs are not secured in sets of two each but each spring 36 is secured to the adjacent springs by means of links 37 which are disposed in the groove in the same manner as the links 25 in the form of the invention already described.

In Fig. 6 a different type of ironing element is illustrated. |The ironing 'element in this case consists of a pressing shoe or board used particularly for pressing clothes. The board 45 is groov'ed, as shown at 4G, and springs 47 are secured to the board over the grooves in the manner shown in Figs. l to 4 or in Fig. 5. At one end of each set of springs there is provided an eye bolt 50 having one end 5l threaded and provided with a nut 52. rIhe eye bolt is connected to the end spring and extends through a flange 53 at the end of the board or shoe. By turning the nut the set of springs can be placed un der tension and securely held in position. The springs are covered by a suitable cover-` ing 48 as in the other embodiment of the in` vention.

From the foregoing description it will be seen that a simple, practical and inexpensiveY spring pad structure has been vdesigned and that spring padding can be'easily, quickly and economically secured to any desiredsurface in the manner described. Furthermore, it Will be clear that the springs Will be firmly and securely held in place.

l Although certain specific embodiments of the invention have been particularly shoWn` and described, itWill be understood that the invention is capable of modificationand that changes in the construction and in the arrangement of the various cooperating parts may be made Without departing from the spirit or vscope of the invention, as expressed in the yfollowing claims.

What I claim is: l

1. A resilient pad structurefcomprising a member having grooves therein, a plurality .of springs, and linksv connecting and securing said springs and disposed in said grooves.

my hand this 7th day 2. A resilient pad structure comprising a member having a groove therein, a plurality of springs disposed over said groove and seated against the surface of the member, and means connecting said springs anddisposed in said groove.

' A resilient pad `structure comprising a member having groove therein, a plurality of sliirings disposed over said groove `and seated against the surface of the member, means connectingssaid springs and disposed in said groove, and anchoring means for seagainst the surface of said element, and

7. In combination, a member having a groove therein, a resilient pad structure securedvto said member and comprising a plurality of sets of springs, each set comprising a pair of springs having their bases connected together, and means in said groove secured to and connecting said sets of springs.

8. In combination, a member having a groove therein, a resilient pad structure secured to said member and comprising a plurality of sets of springs, each set comprising a pair of springs having their bases connected together by an` integral connecting member, and means in said groove secured to and connecting said sets of springs.

9. In combination, an ironing roll having a circumferential spiral groove therein, a plurality of springs having their bases seated against the surface of said roll, and means in 'said groove for securing the springs to the roll.

An ironing roll comprising a shell having a spiral groove in its outer surface, ya plurality of springs arranged spirally around said shell over. said groove, means in said groove securing said springs to each other, means in said groove securing the end springs to said shell, and a flexible covering surrounding' said springs.

In Witness Whereof,`I have hereunto set of December, 1927. i FRANK M. PRATT.
