COMBINED IRONING'AND' FOLDING MACHINE.

Application filed December 19, 1919, Serial No. 346,067. Renewed November 12, 1921. Serial No. 514,822.

kind used in connection with the ironing,

mangling, pressing or drying of sheets of flexible material of anykind,

The objects of the invention are to produce a single machine of this kind which performs two operations on the articles, namely the ironing, smoothing or mangling and the folding of the same; also to provide a machine of this kind which is compact in arrangement and in which both operations of ironing and folding can be accomplished in practically the same amount of floor space heretofore required for ironing alone; also to provide feeding means of improved construction for conducting the articles from the ironing mechanism to the folding means; also to improve the construction of machines of this kind in other respects hereinafter specified.

The accompanying drawing is a side elevation of a combined ironing and folding machine embodying the invention, the folding mechanism being shown diagrammatically.

A represents the frame of a machine which may be of any usual or suitable construction and on which suitable ironing, mangling or smoothing mechanism is arranged. The ironing mechanism shown in the drawings iiicludes a steam chest B which may be of any usual or suitable construction and may be heated by steam or other means. The upper face of the steamchest is provided With depressions into which a plurality of padded rolls C extend, the rolls being rotated by any suitable means, (not shown), in the direction indicated "by the arrows, so as to feed the material to be ironed or mangled from the receiving end b of the steam chest to the discharge end 5' thereof. The articles to be ironed or mangled are advanced over the surface of the steam chest by the'padded or cloth-covered surfaces of the rolls and. are ironed or smoothed by engagement with the smooth and heated surface of the steam chest B. After the ar- Specification of Letters Patent.

Patented May 23, 11922.

holes have passed to the discharge end b of the steam chest they are taken up by an endless apron D passing over rolls d and are carried onthe upper run of this apron in close proximity to, or in contact with the steam chest B, so as to effect a further drymg of the articles. All of these parts have heretofore been used in connection with ironing machines or mangles and of themselves constltute no part of this invention. In ironing machines as heretofore used, means were provided for taking the sheets from the apron D at the receiving end of the machine and returning them to the discharge end of the machine, but these means are dispensed with in the improved machine and the ironed or mangled articles pass to the conveyors or tapes of a folding mechanism at the front end of the machine and may be discharged at the rear end of the machine in folded condition.

In the construction shown, thisfolding mechanism includes a suitable'conveyor E for the articles, which may be in the form of an endless apron or of a plurality of end less tapes passing over a roller 6 at the receiving end of the machine and over the rollers e e and e Any of these rollers may be driven in any desired manner to impart movement to the conveyor E. The conveyor E also bears against the roller 03 of the conveyor D in such a manner that the articles immediately upon passing out of contact with the steam chest B are taken up by the conveyor E which passes the articles to the folding mechanism. After passing on to the conveyor E, the articles to be folded engage a contact device F, having a part which extends into the path of movement of the articles to be folded and which closes an electric circuit, not shown, during the time that the article to be folded is in engagement with the contact device F. G represents the first folding member which is represented dia grammatically in the drawing and which when not in operation occupies the position shown in dotted lines at 9. When the part of the article to be folded reaches the. path of movement of the folding member G, this member is moved into the position shown litlti ried around the roller 6 between the conveyors or tapes E and H.

The mechanism for effecting the folding of the articles, including the contact member F and the folding member G, preferably aotsto fold each article at a distance from the ends of the article proportional to the length of the article and is not shown in the drawing. This timing mechanism connecting the contact member F and the folding member G may be of any suitable construction, for example, the timing mechanism may operate in a manner similar to the mechanism shown in Patent No. 1,313,713, of Aug. 19, 1919, assigned to me. No attempt is made in this application to describe the operation of the timing mechanism for causing the actuation of the folding member G at a definite interval of time after the article has passed the contact member F, since mechanism for accomplishing this result is fully described in my hereinbefore mentioned patent. I represents diagrammatically a housing or container for the timing mechanism. The tape H is preferably partly covered by means of a guard h which prevents the article to be folded from being carried between the conveyors E and H before the actuation of the foldin member G.

Before the article which has been folded by means of the folding member G is discharged from the conveyor IE, it passes and actuates a second contact member K which may be of similar construction to the member F. This member makes contact to complete an electric circuit while the folded article is in contact therewith and is operatively connected through the timing mechanism with the second folding member L. The articles to be folded for the second time are discharged from the'first main conveyor E to a second main conveyor referably consisting of a plurality of tapes I passing over rollers on m and m The folding member L may be constructed as shown in the patent above referred to so as to extend into the other suitable receiving means at the dis-' charge end of the machine.

In case long sheets are folded the sheets after-passing over the shield or guard h will fall upon the tapes M and will be carried by the same toward the discharge end of the machine until the folding member G is actuated, whereupon the article will be drawn back and passed between the rollers e 6?. By means of this arrangement ofv the first and second main conveyors E and M, lon sheets Will not be creased before the fol ing and a very compact arrangement of the folding mechanism is made possible, and since the sheets do not actuate the contact member K until after they have been folded, the passing of the long, unfolded sheets upon the tapes M .will have no effect whatever upon the second folding member L, since the contact member K is only actuate-d by sheets which have been folded by the member G.

The arrangement of the folding devices beneath the steam chest of the ironing machine is extremely desirable since it utilizes a space which is now of no use and furthermore a more thorough drying of the sheets is effected owing to the fact that the same are folded in close proximity to the steam chest B. By means of the folding mechanism described, the sheets, after passing through the machine are discharged in a condition in which they can be easily handled by a single operative for further folding, if desired, or for removing from the plat-form P. The arrangement of the folding mechanism underneath the ironing machine also effects a very material saving in the floor space necessary, since both folding and ironing machines require a large amount of floor space in order to enable them to handle large sheets of material. The folding mechanism also helps to insure proper drying of the articles since the tape conveyors support the articles in such a manner that the moisture may pass from the articles through the spaces between adjacent tapes. The folding mechanism further helps the drying of the articles by passing the samethrough the machine by a circuitous route and by passing the same from one set of tapes to another.

The machine shown in the drawings and described includes a flat work ironer of well known construction, but it is understood that it is not intended to limit the invention to use in connection with an ironer of this kind since ironing apparatus, manglesor analogous machines for smoothing or drying sheets of substantially flat material may be used in place of the fiat work ironer shown and described, and the word ironing as used in the specification and claims is not intended to limit the invention to use in connection with ironing machines of the kind shown, but is intended to apply to mangling and analogous machines for smoothing or performing similar operations on the articles.
