SPECIFICATION forming part of Letters Patent No. 451,479, dated May 5, 1891.

Application filed May 28, 1890. Serial No. 353,456. (No model.)

To all whom it may concern.-

Be it known that we, ARTHUR T. IIAGEN and DANIEL M. COOPER, of the city of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Mangles; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

Our present invention relates to mangles orironing-machines for ironing sheets, towels, napkins, bed-spreads, due, and has for its objects to provide a machine simple and cheap 111 construction, in which the pressure on the articles may be readily contr0lled,and one in which the articles operated upon may be fed into the machine straight and in position to be properly acted upon by the irons 3 and to these ends the invention consists in certain novelties of construction and combinations of parts, all as will be hereinafter fully described, and the novel features pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is aside elevation of a machine constructed in accordance with our invention; Fig. 2, alongitudinal sectional View of the sameon the'line a: 03; Fig. 3, a top plan View; Fig. at, a front view; Fig. 5, a detail sectional view of the end of one of the rollers and irons; Fig. 6, a detail side elevation, partlyin section, of the feeding-roller.

Similar letters of reference in the several figures indicate similar parts.

The main frame of the machine preferably consists of the two side pieces AA, connected at the front or feed end by brace A and at the rear by a tien'od A Mounted in boxes I) b in the side frames A A are the rollers 13 B B B (in the present construction four being employed,) said boxes sliding in guides and being normally pressed downward or toward the irons by springs c, the tension of which may be regulated by han d-wheels cl. Upon each end of the rollers, which are suitably padded, as usual, are located gear-wheels O C, between whichrare arranged idler-gears D, mounted on studs secured to the sides of the frame, causing all of said rollers to be rotated in the same direction, the teeth for said wheels beinglon g enough to permit the necesgears G G G G.

consists of a series of recessedsurfaces, in

sary movement of the rollers without being disengaged.

The main shaft E, journaled in the frame, extends clear across, and at one end is pro- .vided with abelt-pulley F, and near the other with a gear G, from which motion is transmitted to the rollers B Bll B by a train of The iron for the goods which the rollers partly enter, as shown, so as to give great surface contact, and for convenience in construction we I prefer to make this in sections H II 11 11 having at the ends flanges h, by which they are bolted or otherwise secured to bars J J ,constituting aframe pivoted on tie-rod A at the rear end of the machine and supported at the forward end upon suitable adjusting devices, further described. The top surfaces of the abutting sides of these sections are rounded and fitted together, as shown, so that when they are secured to the bars J a continuous ironing-surface will be formed, and they are also preferably arranged on an incline, as shown, the front roller and iron being highest, so that the goods can readily and naturally pass through the machine and be acted upon by the various rollers in succession withoutliability of getting out of place or requiring the operator to guide them in a certain definite course. This arrangement serves, also, to bring the feed end at a convenient height for the operators feeding the machine who stand, while those receiving the ironed articles can conveniently sit down and fold or otherwise dispose of them. Any suitable devices can be employed for heating these sections of the iron; but we prefer to connect steam-pipes g to their opposite ends and circulate steam through them.

The forward ends of the bars J are provided with bossesj, entering recesses or sockets inthe ends of bars or rods K, which latter are-threaded near their lower ends and pass through correspondingly-threaded nuts L, resting on the brace A of the main frame. Connected to or formed upon these nutsare worm-wheels L, with which engage worms L on a shaft M, journaled in the. frame and adapted to be rotated by a handle or crank M, so that by the rotation of the shaft the front ends of bars J will be elevated or depressed and the pressure between the rolls IOC and iron regulated as desired. A suitable scale m is provided on the front of one of the sides of the main frame, with which co-opcrates an index or pointer n on one of the bars J, (see Fig. 4,) so that the desired adjustment can readily be had.

The pivotal point (rod A'-) of the frame, it will be noted, is quite near the center of the rearmost roll B, and said frame moving in the are of a circle comparatively little variation of the pressure of this roll and its co-operating surface will be had when the frame is adjusted, and this constitutes one advantageous feature of this machine. In ironing one class of goodssuch as sheets, towels, and the likeit is desirable that the goods be soft and pliable, and this is caused by gradually drying and ironing them, and with another class of goods it is desirable to have them more or less stiff without being starched, which is caused by drying and ironing them at first with pressure and heat, and the pres ent machine is designed to accomplish this. The pressure between roll B and its ironingsurface remaining practically constant, by lowering the outer endto the lowest point the pressure between roll and its co-operating surface will be least and gradually increasing in the other rolls up to roll 13, thereby first lightly pressing and drying and lastly ironing the articles, and by moving the outer end of the iron up to the highest point the pressure will be greatest between roll B and its cooperatin g surface, and that between roll 13' and its co-operating surface will be the least. These adjustments enable the operator to regulate at once the machine to accomplish the results desired, the scale and pointer serving as guides.

Instead of employing two rods K at opposite sides of the machine, it is obvious that the bars J J could be connected at their forward ends and asingle adjustable device applied in the center; but we prefer the arrangement shown.

At the feeding end of the machine, which we denominate the front, is arranged a trough or receptacle 0 for containing the articles to be ironed, having a table or ledge P, on which the edges of the articles are spread preparatory to entering them in the machine, and at the rear is located a table or support X, on which the articles are received after be ing ironed.

In machines of this class, where long irons and rollers are employed between which the articles, such as sheets, are passed, great difticulty has been experienced in properly entering both ends, as otherwise one corner or portion might be drawn in in advance of the other, the article pulled through crooked, and wrinkles formed, and oftentimes this would occur through the operatives unwillingness to put her hands close enough to the iron to enter the article properly through fear of an accident. Vith the idea, therefore, of providing an improved device whereby the operator may properly position the article without-danger to herself and feed it to the machine so that it will be ironed and dried smooth, we provide a roller or equivalent feeding device under her control, which may be brought into contact with and feed the article properly to the pressing devices.

In the present embodiment of our invention this feed-roller R is mounted upon arms Q Q, journaled upon the journals of roll B or suitable studs, if desired, and connected with said roller by means of a sprocket-chain S, passing over wheels S S on the shafts of said rollers R and B, respectively, so as to be rotated therefrom. The arms Q are connected by rods 25 with a treadle T, pivoted on the floor,

said rods having adjustable collars r thereon,

between which and lugs on the frame are arranged springs e, which tend. to raise the rods and the roller R above the support P; but the operator can, when desired, move the treadle down and bring said roller down on the article spread upon the support, as will be readily understood. Instead of employing springs to lift the roller, a weight could as well be employed, if desired. It will be noted that the rollers are arrangedon an incline, in order that the article being operated upon may readily pass from one iron-section to the next without danger of being wrinkled or improperly received, and upon the rear side of the first roller or subsequent rollers, if desired, is arranged one or more weighted scrapers V, pivoted on shaft \V, adapted to prevent the articles from sticking to the roller and wrapping around it. These scrapers may, if desired, be turned back out of operative position, as shown.

The operation of the parts will now be readily understood. The article to be operated upon-say sheets or other long piecesare placed in the trough O, and the operator then lifts up the edge and arranges it perfectly flat and straight upon ledge 1, ready for introduction into the machine, and then steps on treadle T, bringing feed-roller R down upon it and causing it to be carried with its edge straight between roll 13 and its co-operating iron-section, where it will receive its preliminary pressing and drying, then, passing to the next iron-section and co-operating roller, will be again operated upon, and so on until finally delivered at the end of the machine upon table X.

It is obvious that instead of mounting the irons 011 the adjustable frame the rollers, by a simple arrangement, could be made to adjust toward and from the irons, the latter being stationary, and this we regard as the equivalent, broadly, of the arrangement shown, the details of construction being of course modified; but the feature of mounting.

one of the co-operating parts on a pivotal frame, the adjustable feature described, will be preserved.

By arranging the rollers and iron as described the adjustments can easily be had and ITO the separate ironing-sections can readily be removed,if necessary or desirable. The Whole machine is simple, easily operated, and, as we have found by practical operation,is admirably adapted for the purpose.
