FLATWORK IRONER Application filed January 539, 1930. Serial No. 421,892.

The invention relates to laundry and dry cleaner machinery, more especially to socalled iiat work ironers of eithervthe chest or cylinder type of iroiier. y

It has for its object means for directing the work leaving one roll to the succeeding roll, and more especially toV eliminate the unsightly string marks from the work, being particularly adaptable to laundry machinery wherein the work is stripped from the rolls by suitable flexible stripper devices, for example, in the manner more particularly set forth in my lDatent 1,867,741 granted to me July 19, 1932. Through the use of such stripper devices no string marks areu present in tlie finished work even whenstrings ork the like are employed in connection with the first roll-all traces thereof being obliterated by the action of the subsequent rolls.

A further object of the invention resides inA means to enhance the effectiveness of operation of the machinery by kpreventing the work fro-m rising unduly in the space between the successive rolls of the ironer, and thus obviate temporary shut-downs and work turnbacks. The invention is more particularly adaptable-to ironing machines in which pro- Y vision has been made for preventing the Bill dropping down or 'backwardly from a roll of'its cover cloth which is lapped thereon, for example, by means of guard members and in the manner set forth in 'my aforesaid patent.

In carrying out the invention, there is associated with' the usual rolls of a flat-work ironer, provided with suitable guard or binder members located longitudinally thereof at required intervals and bearingrbotli on the feed and delivery sides of a roll to insure the retentionof a cover cloth firmly thereon as well as to prevent said cover cloth from dropping down or baclrwardly, extensions or guide toes or lilre members arranged to project outwardly from-these guard or binder members both at the feed side of a roll and atjits delivery side;

These guide toes arebowed to conform to the steam chest periphery andare adapted to engage with the Work fed to a roll as it issues therefrom in the event of its rising beyond a' predetermined distance, as well as serving to assist in the progress of the `Work betweeni rolls. The said guide toes, vmoreovenare. arranged to yield in case of unavoidable jam, either through their inherent elasticity or; that of a carryingguard member or in beingi flexibly or hinge'dly connected therewith;`

rEhe nature of the invention, however, willv best beunderstoo'd when described inV con-1 nection with the accompanyingdrawings, inwhich: Y

Fig. 1 is a fragmentary plan view of aflatV work iro'ner equipped with t-hefn'ovell work-directing means. j F'g. 2 is a fragmentary vertical section ings, and on an enlarged scale. y. Fig. 3 is a fragmentary longitudinal sec-; tion through a fiat work ironer and illustrates the application of the novel guidingl members thereto. v Y 'j Fig. l is an enlarged vertical section through aroll and combined guard and-guide member, with portion of work passing therethrough in the direction indicatedby the arrows. t

Referring to the drawings, the inventioni's illustrated, by way of example, as applied to an ironing machine of the chest type having a plurality of ironing rolls 10 which are adapted to iron fiat work, such as bed and" table linen, etc. The said rolls to this end v are journalled for rrotation abovea. steamheated chest 11, the surface of which immediately beneath each roll is generally concave to secure greater ironing contact.` -Noclaimis made to the apparatus per se, thejsame'being of any well-known or specialdesign andi provided V'with standard mechanism (not shownyfor rotating the individual rolls.` Y

These rolls are covered with a cloth covering 12, usually hair padding, wool pad' ding or matted padding which is frictionally held thereon by being wound thereover with lapped portion 18 to insure 'retentionof the cover on the roll surface. Said cover cloth, particularly at the lapped' portion 13, has a tendency to work `away from the under`i` lying cloth portion on the return travel; and provisionhas been made, in the application' SUL" of suitable guard or binder members let thereto, to prevent this breaking away and doubling over, as is more fully set forth in my said Patent 1,867,741.

These guard members aie associated with the individual rolls, as shown, and extend over substantially the exposed portion of a roll to bear both upon the feed and delivery sides thereof, serving to retain the cover cloths thereon, and are disposed longitudinally of a roll preferably equidistantly at the required intervals.

As a convenient means of thus positioning the various guard members, brackets 15 extend longitudinally over the ends of a roll, being secured to the side frame pieces 1G of the ironing machine; and the said brackets support also a hollow triangular holding member 17 positioned over a roll parallell to its longitudinal axis and held to the respective brackets by means of upright supports or posts 18 screwed thereto and beveled at the top. The side walls of member 17 are brought together over said beveled portion and are secured at their upper edges to close the niem-vr ber, as by riveting. Angle pieces 19, furthermore, are-attached to the underside of the member 17 to hold between their downwardly directed sides, as by means of a Cotter pin 20, Van upwardly-turned slotted spur 21 of supports 22 to which the guard members are welded. The said guard members7 moreover, are preferably of resilient material and more or less semi-circular in form to cover substantially the exposed portion of the roll with which they coact. Y

Stripper members 23 are also shown associated'with a roll, on the delivery side thereof to strip from themthe work2el as it passes from one roll to the next, all of which is more particularly set forth in my aforesaid patent. These stripper fingers may conveniently be secured by notching the inner ends thereof as at 25 and inserting the same through corresponding slots 26 inthe corresponding side ofthe hollow holding member 17.

In the operation of flat work ironers in which the usual Vendless work-conveying members, as cords or tapes, are dispensed with in whole or in part and stripper members, as the fingers 23, substituted therefor, there may be a tendency for the work to rise between rolls above'the surface of the steam chest, yfor example, as indicated in Fig. 4 of the drawings, and particularly at the feed side of a roll.k Y

In accordance with the invention there are, therefore, provided guide toes 30 at the feed side of a roll, which toes may be associated with the corresponding guard members 14 either integrally or in being hingedly secured thereto; and the same are designed to yield under sufficientV pressure 'as in being inherent- Y ly flexible or flexibly or hingedly connected with the corresponding guard member.

F or example, the end of a guard member at the feed side may be continued substantially horizontally outwardly over the steam chest periphery and curved to conform substantially thereto, the extreme outer portion of the extension being turned over, as at 31, to afford a smooth edge. It is preferred, also, to provide a correspondingprojecting portion or toe 32 at the delivery end of a guard member, in accordance with the arrangement set forth in my aforesaid patent, and the projecting toe from the guard member of one roll is then arranged to coact with the corresponding projecting toe member of the succeeding roll to substantially bridge the intervening space, as is more clearly set forth in Fig. 8 of the drawings. These coacting toes are arranged, preferably,to then lie adjacently each other and the one on the feed side slightly above the plane of the coacting toe to avoid obstructing the flow of the work, and thus serve, also, to limit the rise of work passing from one roll to the next and guiding it thereto if required, being displaced from the chest surface a distance to permit normally the work to pass freely from roll to roll.

By the foregoing expedient, the eectiveness of the operation of the ironer is greatly enhanced in that shut-downs and turnbacks are obviated; and the arrangement is particularly suitable for use in laundry and dry vcleaner machinery not provided with the usual endless work-conveying cords or tapes, being thus especially-adaptable to machinery equipped with flexiblework-stripping fingers.

1. In a flat work ironer, including a succession of ironing rolls with lapped cover cloth:

guard members associated with the individ- Y ual rolls, extending over substantially the exposed portion of a roll and bearing upon both the feed and delivery sides thereof to retain zontally therefrom over a portion only of the intervening roll space at the feed side of a roll,

andV at the delivery side thereof, the toes o f successive roll guards coacting to bridge the intervening space between the successive rolls for limiting the rise of work therebetween.

2. In a flat work iro'ner, including a succession of ironing rolls with lapped cover cloth: guard members associated with the individual rolls, extending over substantially the exposed portion of a roll and bearing upon both the feed and delivery sides thereof to retain its cover cloth thereon, and yieldable guide toes associated with the respective guard members and extending substantially horizont-ally therefrom over a portion only of the intervening roll space at the feed side of a roll and at the delivery side thereof, the toes of successive roll guards eoacting to bridge the intervening space between the successive rolls for limiting the rise of Work therebetween and the toe on the feed side of a roll being slightly above its coacting toe.

In testimony whereof I aix my signature.
