CHICAGO, ILLINOIS, A CORPORATION OF momnamonmn.

Application filed May 14,

To all whom it may concern:

Be it known that I, WILLIAM SHIPLEY GREY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Ironing-Machines, of which the following is a specification.

The present lnvention relates to ironing machines, and particularly that type of ironing machines in which the goods to be ironed are passed between a cylinder and a roller or rollers, of which the former isusually made of relatively large diameter and provided with means for keeping it up to a high temperature, while the latter is usually of smaller diameter and employed in one or more units coacting with the cylinder and having means for forcing it, or them, toward the cylinder to develop the necessary ironing pressure.

Heretofore it has beencustomary' to clothe the smaller roller or rollers with a material that lends to them the inherent quality of yielding under inequalities in the thickness of the goods, such, for instance, as may be developed by buttons or other attachments carried by the goods but this clothing involves considerable expense in maintaining it. Moreover, it reduces the coacting roll to the capacity of a mere pressure device, without any ironing effect upon the surface of the goods with which it contacts, besides reducing to a certain extent the ventilation of the goods or the evaporation of their contained moisture under the heat of the main cylinder.

One object of the present invention is to eliminate the clothing from the coacting rolls of an ironing machine, to which end the. roll or rolls of such a machine have the surface so dressed that it may bear directly upon the upper surface of the goods and not only develop the necessary ironing pressure but produce an ironing effect over the upper surface of the goods in addition to that which is produced b the main cylinder on the under surface. 11 order that the coacting roll may com ensate for unevenness in the thickness of t e goods being ironed at any point Without interru ting the ironing effect of the remainder of the roller, the

roller is subdivided into a-series of short cylindrical sections supported in operative relation to the main cylinder with freedom to recede therefrom, one independently of the other, but each adaptedto maintain ironing pressure under normal conditions.

Another object of the invention is to maintam ventilation of the goods being ironed necessary to permit evaporation of their contained moisture under the heat of the main cylinder, and to this end, the independently yieldlng cylindrical sections of the roller are spaced apart to leaveventilating ridges between them'; and in order that the entire surface of the goods may be treated alike, a duplicate roller of subdivided and spaced apart cylindrical sections is located in position to act upon the goods after they leave the first roller, and has its ironing sections alternated in position with those of the first roller so that they correspond in position with the spaces between the sections of the first roller.

The roller sections may be mounted so that they maintain ironing pressure solely through gravitation; or they may be held under the influence of means that increases their pressure over that which would result from their inherent weight. The roller sections may be guided ,in their movement to and from the surface of the main cylinder by confining them between a pair=of guide rolls located at opposite ends'of a diameter of the roller which is perpendicular to the direction of their intended movement; or each roller section may be mounted upon a radius arm or between a pair of radius arms extending from a suitable pivot rod. The sectional coacting rollersmay receive their drive solely through friction of the goods being fed by the'main cylinder, or they may be positively driven through independent means.

Two embodiments of the invention are shown in the accompanying drawings by way of illustration. In said drawings- Figure 1 is an end elevation of a known type of cylinder ironing machine in which the eooperatin rollers ordinarily employed are substitute by the rollers of the present invention.

Fig. 2 is a plan view of the same.

Fig. 3-is a viewsimilar to Fig. 1 showing a modified method of mounting the coacting arms used for mounting a roller section of Figs. 3 and 4.

planes transverse to their axes into a series of short cylindrical sections 2* which, ac-

cording to Figs. 1 and 2, are confined between the guide rolls 3 located insultable I position to prevent displacement of the roll-' ers in a direction circumferential to the cylinder 1, and at the same time permitting:

1 limited displacement of the rollers from the cylinder in the direction in which they tend to move under unevenness in goods that may be fed through the machine. Inasmuch as the sections 2 may yield independently, displacement of one from the cylinder 1 will not interrupt the ironing effect of the others.

Since these sections have limited spaces develo ed between them by the bosses 2 ventilation of the goods or evaporation of their contained moisture is permitted to take place through thespaces. In order that the entire surface of the goods may be treated alike, the sections of the second roller 2 correspond in position to the spaces between the sections of the first roller, and the spaces between the sections of the second roller correspond to the ironing surfaces of the sections of the first roller, so that in passin under the second roller unfinishedzones o the goods receive the ironing treatment, and undried zones are afforded an equal opportunity to give off their moisture.

Obviously, the sectional rollers 2 may be multiplied in number if desired.

In the embodiment of the invention shown in Figs. 1 and 2, rotation is imparted to the rollers 2, 2, by the friction of the goods that are being fed through the machlne by the main cylmder 1.

If it be desired to positively drive the rollers 2, any suitable arrangement may be employed for this purpose, such, for instance, as the frictiondrive roll 4 (shown in Figs. 3 and 4) which is keyed upon'a shaft 5, to which positive rotation is imparted at a speed commensurate with the rotation of the cylinder 1, as, for instance, through the medium of the belt 6. Also, if it be desired to maintain a more accurate control over the rollers 2, or guide them more positively in their movements to and from the cylinder 1, they may be guided by radius arms 7 ivoted upon the shaft 5, as suggested in igs.

' ironin 3 and 4. In this arrangement the radius arms will enter the spaces between the roll sections 2 and be'connected with said sections throu 'h-means of pintles' 8; and in order that t e radius arms may enter into h ll 2 are bdi id d i Finally, if it be desired to increase the lroning pressure of the rollers 2, 2, the radius arm 7 will afford a convenient means for embodying this feature in the-machine, as for instance, by providing them with horns 9 pro'ecting in position to receive a I claim: 1.
