SPECIFICATION forming part of Letters Patent No. 790,549, dated May 23, 1905.

i Application iiled April 29, 1904. Serial No. 205,612.

To all whom/it www concern:

Be it known thatLWILLIAM BARTI-IOLOMEW,

lacitizen of the United States, residing at New York, in the county of New York, State of New York, have invented' certain new and useful Improvements in Edge-Smoothing Machines,

` of which the following is a specification, refironing operation; and the present invention has for its object to present this `edge toa smoothing-surface having sufficient moisture to`soften.the rough edge and permit it to be ironed by contact with the heated vfacefof the smoothing-surface as such an article is drawn or moved along such a surface. In order to prevent any excess ofy moisture, as well as the impingement of a direct jet of steam upon the article so-treated, which would injure the finish thereof, means are provided in this machine for obstructing the direct flow of the jet of steam, such means being preferably of `an absorbent character and'disposed to intercept the steam-passage extending from a steam-chamber' to the smoothing-surface.

A further'object o f the invention is to provide guide-plates adjacent to the smoothingsurface adapted to facilitate the introduction and movement of the article in contact with said surface and one ofv said Yplates being suitably apertured to prevent the lcollection of moisture thereon and to retain it in a suit-able cooled condition, so that it will not injure the surface of a starched and ironed article placed in contact therewith.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined the appended claims. In the drawings, Flgure l is a perspective .of the invention; Fig. 2, a central vertical secnut A3, into which a steam-pipe Afis threaded and projects downwardly through the steam- 'chamber into the discharge or drip pipe A5.

The steam-pipe is provided within thechami ber A with a suitable outlet A5 to permit the discharge of dry steam into the chamber, while the steam discharged from the lower end of the pipe will also rise through the drainpipe into the chamber, and the moisture or water of condensation will be discharged from the feed-pipe directly into the drain. This drain-pipe may be supported from the chamber in any desired manner '-for instance, by means of the nut A7, threaded into an aperture Aas in the lowerportion thereof and having an interiorly-tlneaded surface to receive the pipe A5.

.Disposed at one side of the chamber A is a sired configuration to accommodate the character of work to be performed thereon-for instance, slightly curved at its opposite ends ISL-while extendinginward from this smoothing-surface are a series of passages B2, extending to and communicating with the steamchamber A, so as to conduct a jet of steam from said chamber to the smoothing-surface.

These passages may be disposed in any pre-I ferred manner; but as herein shown they are disposed radially to the center of the chamber smoothing-surface B, which may be of the de- 5 between the passages to perform an ironing` function in the passage of an article across the face. The direct contact of a steam-jet with a starched and ironed article would destroy the finish thereof, and for that purpose an obxo struction is disposed to prevent this direct flow and to diminish the degree of moisture which will be presented at the open end of the passages. rIhis obstruction may be secured by different means; but as showing a desirable form thereof I have illustrated herein a chamber B3, extending transversely across and intereepting each of the passages, and within this chamber an obstructing medium 1s placedsuch, for instance, as an absorbent-cotton. 2o wick, as shown at Bf-which retards the d1- rect passage of the steam-jet and regulates the degree of moisture which can be applied to the edge of the article brought into contact with the smoothing-surface. For the purpose of supporting this article in contact with the surface and properly guiding the same a lower supporting-plate C is provided, which is suitmably apertured, as shown at C, for the purpose of retaining this plate at a lower temgo perature than the smoothing-surface and also for preventingthe collection of moisture thereon. The plate C is provided with a vertical wall C2, adapted to abut against the lower face of thesmoothing-surface B, and at each end with a rearwardl '-extending luO or ear (1313e- 33 l: b

neath said surface, the opposite ends C* of the plate being suitably curved or deflected downwardly to facilitate the introduction of an article between it and the upper plate D, which 4o is similarly deiiected in an opposite direction at its ends D', as shown in Fig. 1. This upper guide-plate D is provided with a vertical flange D2 and with rearwardly-extending lugs D3, through which and into the lugs C3 of the lower plate extend suitable secu rin g-screws D4,

passingv also through the body of the smoothing-face B.

In the operation of the invention the collar or other article to be smoothed is introduced 5o betweenthe guide-plates, as shown by dotted lines in Fig. 2, and drawn longitudinally along the smoothing-surface in contact therewith. During this movement the moisture emitted from. the steam-passages softens the starch 5 5 upon the edge of the article, which edge is immediately brought into contact with the heated face of the smoothing-surface between adjacent passages and an ironing function effectedwhich restores the finish to the edge while 6o removing any projecting or roughened surfaces whiclifrequently occur upon starched articles, particularly after they are worn to someextent.

It will be seen that the structure of steamcylinder permits the introduction of dry or superheated steam therein and readily conducts therefromany water or moisture which may be carried by the steam-pipe, so that the same will be drained into the discharge or cxhaust pipe at the lower portion of the chamber.

It will be obvious that changes may be made in the details of construction and configuration of this invention without departing from the spirit thereof as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-
