To all whom it may concern Be it known that I, Swear Mon, a citizen oi. the'United States, and a resident of the city or" Qhicago, (look county, Illinois, have invented certain new and useful Improvements in Ironing-Machines; and I do hereby declare that the following is a lull, clear, and exact description of the same, re terence being had to the accompanying drawhugs, and to the letters of reference marked thereon, which form a part of this specification. I *With ironing machines for use in afiording certain kinds of finish for starchcd articles, the rolls are diven at approximately the same perioheral rate of speed. For an other type or finish, for starched articles, the main or heated roll or cylinder is driven at a rateof speed different from the peripherally arranged roll or rolls, thereby necessitating slipping of the heated rollers on the article being ironed to afiord a luster or polish. Various mechanisms have been provided to enable a single machine to impart either kind of finish. As a rule, however, the mechanisms whereby the adjustment is eliected are so complex as to entail considerable loss of time in making the change of adjustment and furthermore, in but a very few ironing machines has it been attempted "to ait'ord two or more driving rates for the heated roll as com )ared to the constant rate for the smaller roll.

The object of this invention is to afford an ironing machine of exceedingly strong, simple and durable construction}, and m which adjusting mechanism is provided whereby the larger or main cylinder may be driven at any of a plurality of rates of speed as compared with the smaller peripherally arranged rolls.

' It is also an important object of the in-- 'ention to afford 'a, shifting" mechanism whereby the drive ofthe main or heated roll may be varied to the peripherally arranged rolls without stopping the operationactuation to change'the driving rate for one machine to be run continuous y of the machine, thus enabljn the ironing and to impart either a dull or a polished finish on any article byquickly adjusting the maehineas the fabric is fed thereinto.

' it is also an object of theinvention to ail'ord an" exceedingly simple shifting mechanism, positive in action and capable of use in any" position of the rolls and capable of set of rolls while the machine is in operalion without mulaugori'ng the mechanism.

.Itis also and liually an important object of the invention to a'llord means whereby the peripherally arranged rolls may be instantaneously thrown away from. the central roll to release any articles passing through the machine should a stoppage be necessary.

The invention embraces many novel features and consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

As shown in the drawings: Figure 1 is a view in end elevation of a device'embodying my invention. Fig. 2 is a similar view of the opposite end of the machine with parts broken. away. Fig. 3 is a fragmentary longitudinal section. Fig. 4 is an enlarged fragmentary detail of a part of the feed mechanism showing the same in section. Fig. 5 is an enlarged vertical section of the steam connection. l ig. (3 is an enlarged detail of the gland therefor.' Fig. 7 is a frag mentary detail view of the shifting mechanism for Varying the drive of the rolls. Fig. 8 is a similar view partly in section and illustrating the construction of the clutch. Fig. 9 is a section taken on line 9-9 of Fig. 8. Fig. 10 is an enlarged fragmentary section taken on line 10-10 of Fig. 3. Fig. 11 is a section taken on line 11 of Fig. 2,

tary section taken on line l212'0f Fig. 2, with parts omitted. Fig. 13 is an enlarged detail of the adjusting member for the roll ers. Fig. let, is an enlarged detail of the shifting lever for lowering the lover feed roll away from the upper feed roll.

As shown in the drawings: Said ironing machine comprises a suitable frame consisting of end members A-A, each of which may be constructed in a single casting and which are rigidly secured or stayed together by means of bolts a, any number of which may be used, and which serve to rigidly hold said end frame members in parallel and unvarying relation. Journaled in said frame near thctop thereof is the hollow main cylinder or roll B; provided at its ends with axial b-7), which cxtcnd through suita le bearings in the frame and of which the gudgeon is provided with an axial bore extending udgeons thcrethrough and into the cylinder and in which is inserted steam pipe 25 secured in with parts omitted. Fig. 12 is a fragmen- This, as shown, is

place by means of a suitable gland N, which affords a steam tight connection between said pipe and the inner walls of the gudgeon. Said pipe at its outer end is threaded into a fitting If, provided with a central partition Z), as shown in Fig. 5, in which is threaded a p pe b, which extends axially through the pipe 5 and into the cylinder to near the opposite end thereof. Said pipe I), is materially "smaller in diameter than the inner bore of the outer pipe b and serves as an inlet pipe for hot steam, which enters the fitting b, from a steam pipe -72, and exhausts from the fitting by means of an exhaust pipe Z1 the steam entering the cylinder through the smaller inlet pipe I)", and exhausting therefrom from the relatively larger pipe b and smaller pipe 17 The main frame members A-A, as shown, are provided with seats in the tgp thereof adapted to' receive the radially a justable bearin boxes Z-d'd d of the peripherally a justable smoothing roll s D, which, as shown, are four innumber and extend paralll the main cylinder B,and bear uponthe periphery thereof normally,

as shown in Fig. 3.

As shown, an adjusting member d, is provided at each side of the machine for each pair of rollers, which supports the bearing boxes and the lower end of the members are extended to form a thrust rod as shown in Fig. 2. For the purpose of guiding each member d, bolts d are secured to the respective frame mem er A or A, one for each adjusting member, and extends through a slot at, in the adjusting member. Said thrust rods extend radially inward at vided with outwardly directed, cylindric boss s adapted to enter tme eccentrically arrah'e slots in the cams D which are pivote on the gudgeon b and b so that when swung in one direction they act to draw the rollers D, firmly down ron the main cylinder and when swung irrt "e opposite direction, owing to the eccentricity of 'the cam slots, they act to moye said rollers D, away from the peri hery of the main roll. As shown also, in ig. 3, each of said bearing boxes is provided with a tension device embracing a spring d, ada ted to bear upon the 'ournal boxes for the s aft of each of saidro ers, and as shown, adapted to be adjusted inwardly by means of a set screw d to regulate thepressureiof the 1 1 upon the main cylinder. As shown, means are provided for swinging said eccentrics in either direction embracing, as shown, a mutilated gear on the lowerend thereof indicated by e, and adapted to be engaged by a pinion e secured-in a shaft 6, w iich extends beneath and longitudinally of the main rided a worm gear e adapted to be actuated by a worm e" on the end of a shaft 6,-

andactuated by a handwheel E, from the operating position, so that by rotating the hand wheel in one direction the smaller, rolls are quickly adjusted from the main'fcylinder, and by turning in the opposite direction, aredrawn firmly into operative bearing thereon. The shaft or gudgeon for each of the smaller rolls D, is provided upon one end with a pinion (i adapted to mesh with a spur gear C,'journaled upon the gudgeon b, of the main cylinder and from whence said smaller rolls are driven. To impart the drive to said rolls a shaft F, is jourualed-in the main frame members beneath the main cylinder, and is provided with a belt pulley f, to enable the machine to be connected with a source of power. Recured on said shaft also, is a pinion f, which mesheswith a spur gear f, on a stud shaftF', and rigidly secured thereto is a pinion f, (shown in dotted lines in Fig. 1), and which meshes with a spur gear 1, on a shaft F As shown also, a pinion f, is provided on said shaft, which meshes 'with the gear C, to drive the same, so thatsaid gear (J, is at all times driven by, the directly connected train of gears through the main driving pulley f. Journaled on said frame are feed rolls indicated by G-G', which coact to deliver the fabrics to be treated inwardly to the cylinder and between said rolls and the main cylinder are smaller coacting rolls G -G, as shown in Fig. 4. As shown, the feed roll G, is driven from the pinion j", which meshes with a gear 7, on the end of said each end of the main cylinder and are proroll The shaft F extends through the frame members, and is provided on its opposite end from the' gear f, with gears g -e-g, of different sizes, each of which is rotatably secured on the shaft, but either of which is adapted to be rigidly engaged on the shaft by means of a suitable clutch, embracing, as shown in Fig. 5), a collar I, secured between the gears and through which and through the shaft extends a longitudinal slot, in which is seated a pin 2', extending trausversely the shaft and collar having threaded engagement atboth ends with the pins i,

which extend through the collar parallel to the shaft and are adapted to engage insuitable aperturcs or notches in the. respective gears, as shown in Fig. 8, and as shown, a push'pin I extends through auaxial aperture in the end of theshaft F and engages said pin or rod 1', so that either of said gears 9 -9 may be rigidly engaged on the shaft to afford the drive fonthemain cylinder,

which is accomplished as follows: A stud shaft 9 is rigidly secured on the main frame member A, and rotatabl secured thereon are the axially connecte gears 9 -9; of

which the gear 9 meshes with the gear 9*, and the smaller gear meshes with the gear g, which, as shown, is larger than the gear 9*. The main driving gear H, for the main cylinder 3, is rigidly secured on the gudgeon b, and meshes with the gear 9 and as show n, also the gear 9 meshes with the gear 5 on the end of the upper feed roll G. In consequence, the main driving gear H, for the main cylinder may be either driven positively from the shaft Fiby means of a gear when engaged by the clutch, or may be driven through a transmission consisting of the positively driven gear 9 when engaged by the clutch, to the smaller gear 9", 011 said shaft the larger gear 9 secured to the gear f and driving back to the gear 9*, then rotatable on the shaft F and which in turn drives the gear H, in consequence enabling the larger cylinder to be driven at a higher speed than when it is driven directly from the gear r As shown also, the upper feed l won at, a ditl'erent rate of speed roll is from the lower with such transmission. The smaller feed ro ls G -G may be driven by means of a gear y on the shaft F driving to a gear as shown in Fig. 4. As shown in Fig. 4:, a feed chute K, is provided to direct the fabrics to be ironed, as for in stance collars or cults, between the feed rolls H G. and between the lower feed rolls G and G inclined bed 7- to prevent the articles falling between the feed rolls and as shown also, an upper guide plate is is provided to rc\'ent the same turning over the upper feed roll G. Between the feed roll G and the main cylinder is also an inclined bed or table ll, so that when the articles are fed between the rolls, the same are delivered continuously through the machine.

The operation is as follows: The cylinders and'rolls are driven at a rate preferably to allord the desired finish for the articles being ironed or laundried. In one finish the la 7 or main cylinder (heated of course, by the steam admitted thereinto), is driven at a very slightly dil'lcrent rate from the driving rate ot the smaller rolls, in consequence, a. highpolish or luster is not afforded to the stare-bed articles ironed thereby, and this is desirable for many articles of apparel. In others, as in the ease of collars and culls, and shirt bosoms, it is desired to allot-d high a. luster or polish possible, and for this purpose, it is desired to afford a considerable ditlercncc between the peripheral rate of the main cylinder and the smaller .olls. This, of. coins accomplished by means of the transmission before described. For instance, when driving the main cylinder direct through the medium of a gear gflwhen rigidly secured on the shaft by means of the clutch, it is obvious that the rate of speed of the n ain cylinder is very much less than is the use when the gear g be permitted to rotate freely on the shaft F and the gear 9' being rigidly engaged to the shaft, when engaged by the clutch drives to a smaller gear 9;, rigidly connected to the large gear 9 and drives back to the smaller, and that again to a larger. In consequence, affording a marked increase in the rate of drive of the main cylinder as compared with the smaller cylinders, or rollers, the rate of which is practically uniform at all times. Owing to this difference in the peripheral rate of the rolls, it is, of course, necessary for one or the other of the rolls to slip upon the article being ironed, and this slipping action produces the desired friction to afford the requisite polish. Should it occur at any time that it is necessary to stop the machine by the use 01 the. hand wheel i the smaller cylinders may be instantly elevated away from the main cylinder, thereby preventing burning and may as quickly be put into operative position when it is desiredto again start the operation. As shown, means are also provided for throwing the lower feed roll G downwardly away from the upper feed roll G, should it be necessary to stop the machine. For this purpose, a cam slot is pro-' vided at the lower side of the disk on each of the gudgeons b--?), and engaged therein is a pin m, of a lever M, which is fulcrumed on the shaft, F and at the outer end of which is supported bearings for said lower roll. When the cam is swung by means of the hand wheel E, so as to elevate the smaller cylinders D, the inner end of said lever M, is thrown upwardly, thus in consequence carrying the outer end downwardly and moving the lower feed roll away from the upper, as shown-in Fig. 2.

Of course, I am aware that variations in detail may be effected without departing from the principles of this invention, and I have shown but one of several arrange merits whereby the desired effects may-be accomplished. I therefore do not purpose limiting this application for patent otherwise than necessitated by ,the prior art.
