SPECIFICATION forming part of Letters Patent No. 553,038, dated January 14, 1896.

Application filed July 14, 1894. Serial No. 517,513. (No model.) Patented in England June 5, 1894., No. 10,878; in Belgium June 15, 1894, No. 110,256; in Hungary June 24,1894,1 To. 665 in Austria September 3, 1894, No.-44/4,581; in France October 8, 1894, No. 238,904; in Germany December 19, 1894,1i0. 79,657, and in Canada May 13, 1895,1io. 48,936.

subject of the King of Prussia, Emperor of Germany, residing at Homb urg-vor-der-Iliihe, Germ any, have invented certain new and useful Improvements in Ironingdlachines, (for which I have obtained Letters Patent in Germany, No. 79,657, dated December 19, 189i; in Austria, N0. eat/1 ,581, dated September 3, 1894:; in Hungary, Jo. 665, dated June 24:, 1894:; in England, No. 10,878, dated June 5, 180i; in France, No. 238,904, dated October 8, 189i; in Belgium, No. 110,256, dated June 15, 18941, and in Canada, No. 48,936, dated May 13, 1895,) of which the following is a specification. r

This invention relates to that class of ironing-machines in which the polished ironingplate is heated and over which the articles to be ironed are passed under the action of press UITG-lOllGIS; and the object of the invention is to provide a simple and practical construction having great working capacity.

My invention consists'of certain features of construction and combinations of parts, to be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of my improved ironing-machine. Fig. 2 isa side elevation of the same, partly in section, on line a: m of Fig. 1. Fig. 3 is a plan view of the central part of the machine, the feeding and collecting tables being broken away and the endless band omitted. Fig. & is a section on line 4: i of Fig. 3, showing the bearing 'plate, rollers, and endless band in lowered position; and Fig. 5 is a similar section showing the same parts in raised position. 7

Similar letters of reference indicate corres ponding parts.

On a suitable frame A a suitable device A is suspended and which maybe either a charcoal, coke or gas heater. The heating device is arranged in such a manner that the heating-gases in order to escape into the chimneyfiue (not shown) must pass through the chamher it of a hollow casting B, which forms a heating-box provided with a polished top or ironingplate l3, and through the tubular exit-flue R located at one side of said box in the direction of the arrow 19, as shown in Fig. 1. In this manner the greatest part of the heat generated is absorbed by the polished ironing-plate B, which serves as the ironingsurface of the machine, whereby the polish is imparted to the article being ironed. An endless band D, of felt or other similar flexible material, moves over and in uniform contact with this ironing-plate B, and is driven by means of a pair of rollers C C, which are j ournaled in the ends of opposite bearingplates P P, and are rotated by means of a gear-wheel G mounted on the shaft Z of the roller 0, and by a gear-wheel G which intermeshes with said gear-Wheel G, said gear- Wheel G being mounted on a shaft 9 which is journaled in opposite sides of the frame of the machine and which may be turned by means of a hand-crank G. The side bearingplates of the said mechanism are supported at one end by means of a pair of arms H, which at their lower ends are pivoted on the shaft g, and which at their upper ends receive the ends of the shaft Z of the roller C, and at the other end by a pair of arms H, which arms H at their upper ends receive the ends of the shaft Z of the roller C, said arms H being fulcrumed intermediately of their ends-that is to'say, at or about the n1idlength thereof on a transverse shaft g. The shaft Z which carries the roller C is provided at one end with a sprocketwheel F, over which runs a sprocket-chain F, which also runs over a sprocket-Wheel F arranged at the corresponding end of the shaft Z, which carries the other roller 0. Said rollers G C may be adjusted to and from each other, so that the endless band D may be held at the proper degree of tension by means of suitable shifting devices, consisting of screw-threaded shanks S operated by turn-nuts S, which are arranged between the forks of forked brackets S said shanks being connected with the bearings 0f the shafts Z Z of rollers C C, and said shafts passing through longitudinal slots S of the plates P. As shown, shaft Z is provided at one end only with a shifting device.

For the purpose of ironing articles of different thicknesses it is necessary that the rollers should press upon the same with a cer-- tain amount of resiliency, so that they will not press upon the articles too stiffiy and in too unyielding a manner. At the same time it is necessary that the rollers should be capable of being brought into close proximity to or of being separated from the ironing-plate B". Both of these purposes are attained in the simplest and at the same time in the most practical manner by means of the mechanism comprising oscillating arms H H, which hold the rollers in position. The extended lower ends it of the arms H are connected by means of chains J or other suitable connections to the arms K on the rock-shaft K, draw-bars M, and treadle L pivoted at L to the lower end of the frame of the machine in such a manner that the arms II and with them the arms H can be rocked on their shafts g g. The endless band D can be, by means of these devices, moved to or from the ironing-plate B; but this movement is accomplished by the. arms H H in such a manner that the said band and the rollers are carried and the same are always maintained in parallel position with respect to said ironing-plate when the parts are in the relative position shown in the drawings.

After themachine has been used for some time the endless band D may require stretching to take up the slack. This is accomplished by the 'shiftin g devices S, by which the shaft Z is moved the required distance away from the shaft Z, but this destroys the parallelism between the arms H H and also between the endless-band and the ironing-plate B. It is only necessary in this connection that, when the endless band is in contact with the ironing-plate, this contact be uniform throughout the bearing-surface of the endless band, as before. This is permitted by constructing the arms H each of two sections respectively h and 77., both of which sections are provided with longitudinal flan ges 71 71?, through which pass the headed connecting-bolts h that are retained in place by the nuts 71 and one of said sections having longitudinal slots for the passage of the bolts, so that said section 71. may be slightly lowered by first loosening the nuts-of the bolts, and then tightening the same after the desired adjustment is obtained. While this adjustment enables the endless band to form parallel contact with the ironing plate, it will be understood that when it is raised off of the plate the parallelism will not exist; but this parallelism is not necessary excepting when the endless band is in contact with the ironing-plate. Mounted in the said bearing-plates P P, between the end rollers C O, which carry the endless band D, are a number of pressure-rollers G which are of the same diameter as are the rollers O C. These rollers 0 in connection with the end rollers, O 0, press the endless band against the ironing plate l3. lVhen placing these rollers C in position, care must be taken to arrange them at suitable intervals apart, as

shown in Fig. 2, so that the steam caused by the heat of the ironing-plate B upon the dam p articles and which passes through the endless felt band should not be retained by said roll.- ers, but be allowed to escape freely into the surrounding atmosphere.

In order to prevent the ironing-plate B be coming overheated, the chamber 75 which is provided within the heating-box B should have at a suitable distance from the ironingplate B a parallel horizontal partition or baffie-plate WV, as shown clearly in Fig. 4: and in dotted lines in Fig. 1, which is located mid way between the top and bottom of the heating-box, so as to divide it into an upper and lower portion. The hot gases strike against the partition-plate W and are caused to pass from the lower portion of the chamber is through the exit-pipe R and directly into the chimney-flue, while by reason of the fact-that the partition-plate ends short of the side wall of the heating-box, from which the exit-pipe extends, some of the gases pass through the opening formed and into the upper portion of the chamber, so that the ironing-plate is not subjected to the high degree of heat 01 the gases in the lower part of. the chamber.

In front of the machine a feeding-table O is fitted tothe frame A thereof at approximately the same height as that of the ironing-plate B. and at the opposite side of the machine a dis charge and collecting table 0 is also fitted. These tables are preferably of the same width as that of the ironing-plate B.

The construction of the heating device A is of secondary importance so long as care is taken to conduct the hot gases in the manner above stated.

The operationof the machine is exceedingly simple and is as follows: The heating device A is fired, so that the heat arising from-the same will be imparted in a sufficient degree to the ironing-plate B. The articles to be ironed having been prepared upon the feeding-table O,the treadle L is depressed andthe rollers and the endless band lifted from ofi the ironingplate. The clothes or other articles are now pushed forward from the feeding-table until they are seized by the endless band. The crank-handle G is now turned in the direction of the arrow II, Fig. 2, and the endless band caused to travel in the direction of the arrow IlI,same figure. The pressure on the treadle L is'now released, and the rollers and endless band are allowed to rest upon the article being ironed, so as to press the same uniformly against the heated ironing-plate l3,while said article is being drawn rearward by the endless band.in the direction of the arrow I until it reaches the collecting-table 0.

Having thus described my invention, l claim as newand desire to' secure by Letters Patent 1. In an ironing-'inachine, the combination. with a frameprovided with'an ironing-plate, of oscillating-arms fulcrumed tothe frame. bearing plates pivoted to said arms, a pair or endless band being always supported in parallel relation to the ironing-plate when the band is pressed against the same, sprocket- Wheels on the ends of the outer r01lers,' a sprocket-chain passing over said wheels, gear- Wheels and means for rotating said rollers through said gear-Wheels, substantially as set forth.
