Specification of Letters Patent. Patented lVIar, 9. 1920,

Application filed December 21, 1917. Serial No. 208,227.

f0 all'whom it may concern:

Be it known that-I, ALVA J. FIsHER, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ironing-Machines,

of which the following is a specification.

My invention relates to an ironing machine and to the roll thereof and the'object thereof is to provide for such roll a. pad of a certain character offibrous material such as jute, whereby .the numerous objections heretofore experienced in practical use with pads of other material are efl'ectually overcome.

In practice pads for ironing machines are made of felt, such as cotton,.wool or hair felt, but all of these materials are open to objection. For instance, the cotton felt, owing to the heat and dampness acting upon it becomes very'hard and dense inasmuch as it holds the moisture coming from v the clothes being ironed and ina short time becomes practically a solid roll. A roll of seven inches in diameter willshrink to about six and one-half inches owing to the fact that the pad becomes packed solid.

In case of wool felt, the thickness thereof is about three-sixteenths of an inch as ordinarily used for this purpose and owing to this thickness there are only about five laps or thicknesses on a roll. As a result the first lap and the last lap cannot meet within about-two inches. otherwise there would be a ridge the entire length of the roll due to the fact thatat this particular point there would be six laps or thicknesses instead of five. Sometimes the ends of'the pads will overlap unintentionally and in this event the roll will not do satisfactory work as it will scorch the material where the ridge exists, or they clothes will not be thoroughly ironed inasmuch as the shoe isheld in contact with springs and consequently where there is an excess thickness the shoe will be released as the ridge comes around and into contact with the shoe. Moreover. a wool felt pad burns very easily with a little'eX- cess of heat and soon becomes discolored to adark brown besides becoming packed very hard. This reduces the strength of the pad and will cause it to break off in pieces.

In the case of the hair felt, a pad made therefrom is not strong and the result is much the same as in the ,case'of the wool felt, particularly as -to becoming hard and I packed and also as to permitting of only a few thicknesses to be applied owing to the thickness of the hair felt which is from one quarter to three eighths of an inch. Moreover it ismore diflicult to apply on the roll than either the cotton or wool felt.

I have discovered that a fibrous material such as jute has the proper characteristics and attributes to form a most efiicient pad inasmuch as it overcomes, all of the objections noted in respect to pads of the other materials mentioned, as well as other advantages as hereinafter noted and. as made apparent from the description of my new pad or illustration thereof in the drawmg.

In the drawing F igure 1 is a sideelevation of an ironing machine in which invention is embodied; Fig. 2 an end elevation thereof; Fig. 3 an elevation of the roll detached, showing the beginning of the op eration of applying the pad thereto; Fig. 4 a cross section on an enlarged scale taken on the line 44 of Fig.3; Fig. 5 a detail elevation of a portion of the roll showing one of the retaining hooks; Fig. 6 a section on the-line 6-6 of Fig. 5, and Fig. 7 a detail view of the fibrous material employed 'for the pad.

In Figs. 1 and 2 I .have shown the type of ironing machine to the roll of which my invention is applied. This ironing machine consists of a main frame 1 which'supports supplemental frames or end brackets 2. In these brackets is journaled the ironing roll 3 on whose-periphery is formed or mounted the pad 4. The shoe 5 is pressed against the pad or rather-against the clothes to be ironed which are interposed between the shoe and the pad. This pressure is a yielding one owing to the pivotal mounting of the shoe and the provision of the springs 6, the details of which it is unnecessary to explain as they are of well known character. The roll 3 may be of the usual construction but I prefer to make the same as shown in Figs. 3 and 4, providing it with a series of hooks 7 arranged at intervals along the length of the roll for'the purpose of en aging the inner end of the material of W ich the pad is formed.

The material of the. pad is of the coarse woven character as shown at 8 in Fig. 7,

such material in practice beingknown as jute. This material is first applied to the hooks of the roll and wound therearound as many times as required to give the necessary thickness or diameter of pad. It is found in practice that such to its original diameter to whatever size it may have been built up to, which invariable diameter is of great importance inasmuch as it provides a uniform ironing surface.

Other advantages of the jute pad are that it is impossible to burn the same with the heat applied bythe ironing machine shoe and that the dampness coming from the clothes being ironed penetrates and escapes through the pores of the jute pad, with the result .that a sheet or tablecloth for instance can be ironed in about twenty-five per cent. of the time required when the, other kinds of pads above mentioned are used. Moreover the pad retains its original character-'.

istics particularly its pliability, so that it is not necessary as in the case ,of the other types of pad to remove and Wash it. Furthermore the cost ofthe jute pad is only a fraction of the cost of the other kinds of pad.

In addition, the jute pad'Will not shrink a pad will hold which is of considerable advantage inasmuch as the danger of the, burning of the pad and goods being ironed is prevented. The ironing shoe being made of metal always retains its radius, and if he pad should shrink as happens to the old describedforms of pads, the area of contact between the shoe and pad is thereby reduced, with the result that the pressure of the shoe remaining the same the greater pressure exerted on the lesser area causes burning of the pad. Also, the jute pad can be advantageously used in connection with rolls having a solid or impervious surface, wherein the only places where the moisture or steam can escape are between the top and bottom edges of the shoe. The

jute pad permits this steam or moisture to pass through its pores and to escape 'adjacent these edges of the shoe.

I claim:

1. For the roll of an ironing machine a pad formed of jute wound therearound to provide a plurality of thicknesses.

2. In combination with an ironing machine roll having a solid or impervious sur-- face, a pad formed of jute and applied thereto.

ALVA J. FISHER.
