THOMAS S. WILES, OF ALBANY, NEW YORK.

IRONINGi-NIACHINE..

SPECIFICATION forming part of Letters Patent No. 384,487, dated June 12, 1888.

Application filed November G, 1886. Serial No. 218,138. (No model.)

To all whom it may concern: l

Be it known that LTHOMAS S. WILEs, a citizen of the United States, residing at Albany, in the county of Albany, State of New York, have invented certain new and useful Improvements in Ironing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to ironing-machines of that class in which the ironing of articles of clothing is accomplished by a metallic roller adapted to beinternall y heated and having a hard smooth surface, (which roller is hereinafterdesignated as an ironing-roller,) which runs in contact with and against a-roller having an elastic covering with a Surface of muslin or other suitable cloth or fabric which will absorb and discharge moisture, (which roller is hereinafterl designatedas the clothed roller,) upon which the articles to be ironed will not slip. so easily as upon the ironingroller in passing between the said rollers while said articles are being ironed. The function of the elastic covering is to temporarily yield to hems, seams, and other thick parts of the article to be ironed, so as to materially prevent undue and injurious strain and compression thereof7 and also to tend to equalize the 1 ironing action of the rollers upon the thick and the thin parts of the article. A pair of rollers, one being an ironingroller and the other a clothed roller arranged to run in surface contact with each other, are generally termed a set of ironing andclothed rollers. It is desirable in machines of this class to provide means for temporarily and duly separating the rollers of a set from each other in order to prevent burning the covering of the one by reason of the heated condition of the other.

Among the other desirable objects in view in this invention is that of protecting the operator or operators from inj ury by being caught in the gearing of the machine or by the contact of the dress or other garment of the opin thefollowing description, and the novel feaerator or operators with a revolving shaft of the machine.

Other objects and advantages will appear tures thereof will be particularly pointed out in the claims. Referring to the drawings, Figure 1 is a perspective of an ironing-machine embodying my improvements. Fig.Zisanendelevatiomwith the gear caps removed from the standard. Fig. 3 is a similar View of the opposite end of the machine, the gear-caps also being removed. Figs. 4 and 5 are perspectives of the standards of the frame-work of the machine. Figs. 6 to 14. are details, hereinafter described.

Like letters of reference indicate like parts in all the figures of the drawings.

My improvements in this instance refer more particularly to the construction of the standards of the machine, whereby each serves to inclose the gearing and to receive and support devices for adjusting the clothed rollers with relation to the ironing-roller, and tothe de- Vices employed for maintaining the standards in parallelism with each other, and to devices for covering the cross-shafts of the system of gearing employed, and to the particular conformation of the separate parts comprised in the machine as a whole, all of which will be particularly set forth in the claims.

Referring to Fig. 1, A and A represents the rollers intended for the reception of the elastic and yielding clothing above mentioned, and B represents the ironing-roller.

y B representsr a doffer, which comprises a metal bar having a plate, B2, of sheet-steel secured to its lower edge, while its upper edge is projected in the form of cylindrical bearings B3, which are supported in cup-shaped recesses B4, formed at the end of brackets,B5 (see Fig. 10,) which are secured in any suitable manner to a fixed part of the machine, and in such position that the plate B2 will naturally rest in contact with the ironing-roll. At the opposite side of the ironing-roll B is another doffer, BG, which rests in contact with the roll, and is supported upon the upper edge of the cross-bar H2.

The objectI of the doffers is to prevent the articles being ironed from adheringto the roll and from becoming wound thereon.

The ironing-roller, as usual, is hollow, and there is provided therein a combined air and gas burner, 0*, of any desired construction, preferably that disclosed in my patent of July 20, 1875, No. 165,775, the several pipes shown being for the admission of air and gas in proportionate quantities determined by the valves IOO C'. At the opposite end of the ironing-roller there is,vas usual, provided a chimney or uptake (not shown) for the escape of the products of combustion.

D represents the standard of the frame-work at the end of the machine at which the burner is inserted, and E* represents the standard at the opposite end thereof. Each of these standards differs from the other in certain features of construction, and yet both have certain features which are similar. A description of cach will therefore be necessary. Ordinary tie-bars, D, are employed at the feet of each standard, but more for the purpose of giving additional strength than from actual necessity, as it will hereinafter appear that by reason of certain novel features of construction said tie-bars are not actually necessary to a maintenance of the standards in a desired parallel position, or for rendering the frame-work of the machine sufficiently firm for the support of the operative parts of the machine.

Fig. 3 is a front elevation, and Fig. 5 a perspective of the standard D. This standard consists of a single casting, which, when finished for use, not only serves its purpose in the completed machine, but may also serve as a pattern for reproducing duplicates thereof for additional machines, or for taking the place of a broken standard, and this characteristic is present or exists in several of the various parts comprising this machine, and I therefore deem it' proper 'to state that where such several parts possess novel features of construction I consider the same covered by my invention whether used in a machine similar to or different in other respects from that shown herein-that is to say, I do not limit the details of my inventions to a use thereof in any particular ironing-machine, but reserve my right to use each novel feature in other ironing-machines than that herein shown and described.

The standard D comprises lugs Dl for receiving the tie-bars D', but such lugs are nonessential features of the standard, and it otherwise comprises a substantially continuous lateral iange, D3, forming, in connection with the main body or inner wall portion, D, niaterial portions of a ease for the gearing employed in the machine. The outline of the standard is such as to form a seat, D1", for the bearing-block B5 ofthe ironing-roller. Above and below said seat there are formed in the standards openings Ds for the reception of the boxes A2 of the clothed rollers. Back of the box-openings D6 there are formed through the standard polygonal openings D7 for receiving the polygonal couplings E of the shaft-covering and tie-tubes F, hereinafter described. These openings D and DT are surrounded on the inner wall side by a raised ledge or border, DS, the object ot' these raised borders being to facilitate planing the bearing-surfaces for the parts arranged adjacent thereto in the completed machine, as it is apparent that difiiculty would occur in case the ordinary cast surface of the standard were used, as in order to get true projecting or thicker and stronger bearing-surfaces the entire inner wall, D, of the standard would necessarily require truing up, by planing or otherwise, to secure satisfactory bearings.

Between the polygonal openings D7 there is an aperture, D, which receives a stud that serves as the journal of an intermediate gear, hereinafter described.

As illustrated in the drawings, the fiange D3 is recessed or rabbeted, as at Dl", the object of this conformation being to receive the gearcaps within the rabbet; but this, it is apparent, is not an' essential feature of the standard, as the caps may be secured directly against a plain edge of the tiange.

The gear-caps are shown in Fig. 1, and they are made in three sections, D, D2,-and D, all being secured by bolts D, which pass into lugs D15, formed as a part of the standard, (see Fig. 5,) or into the iange D, as may be desired.

For the mere purpose of giving additional strength to the feet D16 of the standard, the flange D3 is extended along the same, and between the feet there is formed a depending bracket, D, having a bearing, D, for the rock-shaft G, hereinafter described. On the opposite surface of the portion D* to that shown in Fig. 5 there are formed as a part of the standard two parallel outwardly-projecting anges, D19, (seen Fig. 1,) which serve to receive a table or feed-board. Another feedboard or table is arranged at the opposite side of the machine and supported by brackets H, (see Figs. 2 and 3,) which are secured to the machine in a manner hereinafter described.

` The standard Edf, employed at the opposite end of the machine-that is, the end where the uptake communicates with the ironing-roller, and where the driving-pulleys are arranged, as shown in Fig. l-is similarin many respects to that before described, and is illustrated in Figs. l, 2, and 4. In this standard, near the seat D5, are two projecting posts, Dmk, which are apertured to receive the attaching-bolts of the chimney or uptake. (Not shown.) Below the polygonal openings D7 in each standard is the bearing DY for the driving-shaft of the machine.

The boxes B5 of the ironing-roller B are permanently secured in the seats D5- of the standards and remain stationary,wliilc the boxes A2 of the clothed rollers are movable vertically in the openings D6 of the standards. The lower clothed roller, A', and its bearing are arranged to move downwardly away from the ironingroller,while th'e upper roller and bearing are movable upwardly away from roller B.

By reference to Fig. ll it will be seen that the bearing-block A2 has one or both of its projecting fianges a made removable from its body portion, screws a serving as a means for binding a plate to the body portion, the edges of the plate forming the flanges a. This construction is necessary in order to introduce the ICO block into the openings ofthe standard, the walls of which opening are unbroken.

Referring now more particularly to Figs. l, 3, and 8, it will be seen that there is a coiled spring, I, arranged below the bearing blocks of thelower clothed rollerand asimilar spring arranged above the blocks of the upper clothed roller and within the openings D6. Above the spring in the upper box and below the spring in the lower box there is arranged a plate,l I', which is cut away at opposite edges to fit the opposite walls of the openings Dwhich plate v is inserted in the openings in an inclined position and afterward turned horizontally so as to embrace the said walls.

A tension-regulating bolt, I2, is provided for varying the pressure of the spring upon the box A2. A similar plate and regulating-screw (the latter not shown) are arranged beneath each box of the lower clothed roller. boxes A2 are supported upon the lug J of the suspension-link J, (see Figs. 8 and 13,) which lug projects into the opening D6 of the standard and beneath the box. The suspensionlink is apertured to pass around the shaft without. touching it, and extended upwardly and curved laterally over and above theA lug J, as at J2.` Through this portion J2 the tensionbolt l2 passes. The lower end of the suspension-link is apertured for the pivotal connection of a rod, K, which extends to and is pivotally connected with an arm, K', rigidly secured to the rock-shaft G. An opposite arm, K2, is similarly connected by a rod, K3, with asimilar suspension-link, J, including between its lugs the boxes A2 and spring I and plate I of the lower clothed roll. These elements are duplicated at each end of the machine, upon the endvof the rock-shaft, outside of the standard D,there is secured atoothed sector,G,into which a pawl, G2, pivoted on the lug D15 of the standard D,takes, the pawl being provided in this instance with a projecting horn, G3, to facilitate throwing it into and out of connection with the sector. Upon the face of the sector are two flanges, G, which serve as a socket to receive a lever, X, (see dotted lines, Fig. 1,) which is projected for. easy access by an operator at one side of the machine.

Now, it will be seen that when the outer end of the lever X is depressed the rockshaft is oscllated in its bearings D18 and the arms K are depressed and the opposite arms, K2, are elevated. These motions. of depression and elevation are communicated by the rods K K2 to the boxes A2 at opposite ends of each ofthe Vclothed rollers-that is to say, the rods K draw the boxes A, the links J, and the roller A down, while the rods K3 push the boxes,

links, and the roller A up, so that both rollers may be forced against the ironing-roller in proportion to the distance that the outer end ofthe lever X is-moved, and by means of the pawl this pressure of the clothed rollers may be maintained for a desired time.

The rock-shaft G, the arms K and K2, and the rods K and K2 have been employed in Themachines of this class for moving the clothed rolls toward and away from the heated ironing-roll'and for producingpressure for ironing between the rolls.

Variousmodifications of this system by combining springs or weights and levers therewith have been employed for making the pressure automatically yielding and adapted to Various thicknesses of articles under treatment and for increasing or diminishing pressure at will. To attain these ends more conveniently and perfectly than has been heretofore accomplished by any known device, l employ the following devices: First, the ratcheted sector of rock-shaft with socket for lever and detent ,or pawl, by means of which I increase or di- -varying thicknesses of goods, and the degree of such yielding-pressure is regulated, as is desired, by the actionI of the screws on the Springs.

The standards are preserved and maintained in a parallel position by means of tie-tubes F and a spreader or space-tube, F', and these are connected with the standards in the following manner: Around the opening D20 in each of the standards and upon the outer surface of each standard (opposite that shownin Figs. 4 and 5) is a projecting hub or collar, D21, (see Fig. 7,) upon which the pipe or tube F its, the end of the tube abutting against the standard. This tube serves as a spacer-that is, to determine the distance between the two opposite standards.

In each of the polygonal holes D7 there is a coupling, E, (see Fig. 9,) having a desired polygonal body portion, E, and at one end a flange, E2, and bored longitudinally for the passage therethrough of the shaft, and interiorly screwthreaded on its small cylindrical end for the reception of the exteriorly-screwthreaded tie-tubes F, yth ese tubes being ythreaded right and left, so that when the couplings are inserted and the tubes are turned they will draw the couplings and standards toward each other until the latter abut against the ends of the spacer-tube F. The objectof the polygonal body portion of the couplings is to prevent its turning when the tie-tubes are turned. Each ofthe couplings E is also bored to form a bearing for the shaft passing therethrough. (See Fig. 6.) Through the tie-tubes F the crossshafts of the system of gearing employed pass, and through the spacer-tube F the main shaft of the system passes.

By the construction thus described it is apparent that the standards will be supported IOO IIO

at a proper distance from cach other, and in connection with the usual shoulders formed on the shafts of the ironing` and clothed rollers, and with the anges A of the boxes AZ, the frame-work is adapted to support and permit rotation of the operative parts therein, so that, as heretofore stated, the tie-bars D are not absolutely essential, although the same may be used to give further rigidity to the structure as a whole. All of the rotating shafts, however, are by the tie and spacing tubes covered, and all danger of injury by the catching and winding of the garments of the operator or operators thereon is avoided, so that said tubes provide safety as well as perform mcchanical functions in the construction of the machine.

By reference to Figs. 1, 2, and 3, it will be seen that the main shaft L is provided with the usual fast and loose pulleys, L and L2, and that opposite the driving-pulleys there is secured to said shaft a pinion, M, which meshes with a gear, N, fixed to a cross-shaft, O, which passes through a lower tie-tube, F. Upon the opposite end ofthe shaft O (sec Fig. 2) is the pinion I), which meshes with a gear, Q, secured to one end oft-he lower clothed roller, A.

An intermediate double gear, R, (a dotted line indicating the gear upon the back of the gear It, Fig. 3,) is arranged under the cap Dl, Fig. l, on a stud, S, secured in the aperture D of the standard, (see Fig. 5,) and meshes with the gear N on the shaft O in an inner series of its gear-teeth, (not shown,) while the outer series of its teeth mesh with a pinion, T, secured to the ironing-roller B. A gear, U, meshes with the double gear R, and is mounted on a shaft, V, which runs through the upper tietube F, and has upon the opposite end a pinion, XV, which meshes with a gear, Y, mounted on the shaft of the clothed roller A. The system of gearing is fully illustrated in Figs. 2 and 3, and is such that the vertical movements of the clothed rollers are possible without unmeshing their gears from their adjacent pinions. The form of the gearcaps at each end of the machine is such as to adapt each to the gear it covers.

In Fig. 12 is illustrated the end portion of a casting` H', which is adapted to constitute, when secured to the standards, a tie-bar and the front walls of the seats D5 for the bearings B5 of the ironing-roller. (See H', Fig. 3.) `A proj ectiou, H2, from said casting is formed for the purpose of attaching thereto, by means of bolts passing through apertures Hx, (sec Fig. 12,) the bracket H, which supports the feedtable, it being understood that there is asimilar bracket and casting upon each standard. The table may be secured to the brackets by screws or bolts passing through apertures hin the bracket and into the end of the table.

rlhe operation of ironing articles with this machine is substantially that of other machines of the same class, in that the articles are passed over the table at one side of the machine through and between the upper clothed roller and the ironing-roller, and are ironed thereby upon one surface, and are returned between the ironing-roller and the lower clothed roller by the operator at the opposite side of the machine.

Having described my invention and its op` eration, what I claim is l.
