SPECIFICATION forming part of Letters Patent No. 643,189, dated February 13, 1900.

` Application filed March 4, 1899. Serial No. 707,768. (No model.)

T 0 @ZZ whom t may concern:

Be it known that I, ADAM KREUTER, a citizen of the United States of America, and a resident of Chicago,county of Cook, and State of Illinois, have invented certain new and useful Improvements in Mangles, of which the following 4is a specification, and which are illustrated in the accompanying drawings, forming a part hereof.

My invention relates to that type of machines of the class named in which a padded cylinder is employed in conjunction with steam-chests, garments to be ironed being passed between the cylinder and the faces of the steam-chests; and the objects of the invention are to improve machines of this type by providing the steam-chests With suitable supports by which they may be adjustably held in proper relation with the cylinder and to provide improved means for bringing the steam-chests into action.

A further object is to provide means for drying the fabric with which the cylinder is covered.

These several objects are attained in the construction hereinafter fully described, and which is illustrated in the accompanying drawings, in Which- Figure l is a side elevation of the machine, partly in vertical central section. Fig. 2 is a detail sectionon the line 2 2 of Fig. l. Fig. 3 is a detail section on the line 3 3 of Fig. 1. Fig. A is a transverse vertical section on the line I 4 of Fig. l, and Fig. 5 is a detail of a joint used in the machine.

The machine, generally speaking, com prises a frame upon which is journaled a cylinder, as B, a pair of segmental steam-chests H K being mounted concentrically with the cylinder and supported upon sliding bearings, upon which they "may advance toward or be withdrawn from thecylinder, suitable levers being provided for controlling such movements. The frame comprises the two end standards A A and the side rails o, uniting these standards. At their upper ends the standards are provided with suitable boxes, upon whichis j ournaleda shaft C, upon which is fixed a cylinder B, which is made of sheetsteel, freely perforated, and supported by the spiders b, xed upon the shaft. The cylinder B is enveloped in a textile or felt pad b.

Power is applied to rotate the cylinder by means of a belt-pulley D, fixed upon a shaft d, journaled longitudinally as to and extending the entire length of the frame and carrying pinions d', one adjacent to each end, which pinons el' intermesh with gear-Wheels E,which are mounted upon shafts e, projecting outwardly from the standards A, the hub of the gear-wheel E being prolonged and comprising a pinion e', which intermeshes with the gear-Wheel F,fixed upon the shaft C. This train of gears is in duplicate, one at each end of the machine, in order that the strain may be more evenly applied.

A steam-coil is located within the cylinder B and,as shown, comprises a plurality of longitudinally-disposed steam-pipes Gr, one between each pair of spokes of the spiders b. Steam is served to this system of piping through a steam-pipe c, which may be located at either end of the machine and which enters a suitable longitudinal aperture formed in the end of the shaft C, a stuffing-box c2 being applied 'to the end of the shaft in order to make a steam-tight joint, while permitting the shaft to rotate relatively as to the pipe o. Connection is made between the tubular portion of the shaft C and one of the steam-pipes Gr, as shown at g, and at its farther end this steam-pipe G is united with one of the adjacent pipes of the same character, as shown at g', which in turn is similarly united at its farther end to its next neighbor,

this series of connections being continued so as to connect the entire system of tubing and the last pipe G being connected with a suitl able longitudinal aperture in the end of the shaft C opposite to that at which the steam enters, which aperture in turn is connected with the discharge-pipe c in the same manner as the connection is formed with the pipe c. The cylinder B being perforated, a circulation is provided through the covering-pad b', and as a result this pad is kept dry.

I believe myself to be the first to apply heat to the interior of an open-ended perforated cylinder for the purpose of drying its envelop by the direct action of the heat and by the circulation of air directly stimulated thereby.

Usually machines of this type are entirely unprovided with means for drying the cylinder-envelop. I am aware that it has been IOO proposed to set up circulation of air through the envelop by applying suction to the interior of the cylinder; butthis is inefficient, even though heat may be introduced into the cylinder, for the reason that the air drawn through the envelop is necessarily comparatively cool, and hence lowers the temperature of the envelop, thereby not only checking evaporation, but robbing the steam-chest of heat which should be applied directly to the goods.

The steam-chests H K, which coperate with the cylinder, are segmental in form, their inner faces being polished for application to the goods and being concentric with the cylinder B. These chests are of the samelength as the cylinder. The frame of the machine is provided with suitable brackets, as P, for supporting the steam-chests, and preferably the supporting-faces o f these brackets are flat and in the plane of radiiof the cylinder, two of such brackets foreach of the chests being provided, one at each end of the machine. As usual in machines of this type, one of the steam-chests, H, is set at a greater elevation than the other, K, for convenience of feed and delivery, the goods being fed to l the machine from a table, as'V, carried by the chest H, and discharged therefrom at the.A

upper edge of the chest K, which carries a table W, upon which they may be deposited. The lower edges of the steam-chests overlap, as shown at X, so that when they arebrought up to position for service a continuous surface is presented forbearing against the goods as they are carried along by the cylinder. Each of the chests is provided with coperating brackets 7?, 7c, adapted to rest and slide upon the brackets P, and for the purpose of lsecuring durability, and also for the purpose of providing for a proper adjustment of the chests relatively as to the cylinder, a shoe h is interposed between the brackets h 7c and the brackets P. This shoe shouldbe loosely connected to one of the coperatin g brackets. As shown, this connection is with the chestbracket and is accomplished by the use of dowel-pins h2, preferably fixed in the shoe and loosely entering suitable sockets in the connected, so as to bear upon it.

bracket. A pair of adj usting-screws h3 passes through the bracket with which the shoe is While I have shown the shoe as connected with the chest-bracket, it is obvious that it might be connected with the frame-bracket, and in the latter event the adjusting-screws h3 will be correspondingly changed. By turning down the adjusting-screw h3 nearest to the chest it will be seen that the lower edge of the chest will be thrown inwardly toward the cylinder, while the setting-up of the outer adj listing-screw will result in tilting the chest in the opposite direction, so that its upper edge will be thrown more lnearly to the cylinder.

The details of construction for the support of the two chests being the same, I have not deemed it necessary to describe and fully illustrate more than one.

The movemen of each of the steam-chests is controlled b a pair of lever-arms M O, one member ot each pair being located at each end of the cylinder. These lever-arms M O are pivotally mounted upon a shaft Q, which for the sake of greater strength runs the entire length of the machine, and this shaft is supported upon the frame, preferably by means of brackets q in arch form, supported by t-he side rails a. The connection between the lever-arms M O and the steamchests being identical in form, I have shown in detail only one. The arm M is pivoted to lugs m m', formed upon the outer face of the chest H. As the end of the arm M oscillates with a shaft Q as a center, while the movement of the chest H is a reciprocation upon a right line, in the construction shown conipensation for the diverging. of the paths of the two parts is provided for by making the aperture in one of the parts larger than the pivot-pin 'm2, which unites the arm M with the lugs m. This lost motion does not interfere with the proper action of the machine, while fullyservingthepurposeinview. Each of thel lever-arms M O has a downwardly-projecting arm m o, and between them there is located a cam R, mounted upon a shaft r, journaled in the standards A A and controlled by means of a hand -lever S. When the cams R are turned to spread the arms m o, the steam-chests H K are forced toward the cylinder B. A segmental ratchet U is fixed upon the shaft r, and with it cooperates a gravity-pawl u, which prevents the recession of the parts when the stearnchests are advanced toward the cylinder. Upon the release of the pawl u and the throwing back of the cam R the steamchests fall away from the cylinder, their supporting-brackets being inclined downwardly at their outer ends.

It is necessary in machines of this character that the polishing-surfaces be held to the cylinder by yielding supports, and this is provided for by settin g transversely through each of the arms m o a reciprocating [iat-headed bolt T, against the head of which the cam R bears, and encircling the stem of the bolt with a coil-spring t, the aperture provided for the bolt being counterbored to accommodate the spring. As thus constructed the parts of the machine may be easily adjusted and always kept in proper relation, any wear of the bearing parts being easily compensated for by a readjustment by means of the screws h3.

The chests I-I K are supplied with steam by means of a pair of pipes Z, leading one to each of the chests and being capable of sufficient oscillation to permit of the movement of the chests in the manner described.
