MANGLE.

SPECIFICATION forming part of Letters Patent No. 247,486, dated September 2'7, 1881,

Application filed April 23, 1881.

To all whom it may concern.-

Be it known that I, JAMES G. CRAWFORD, of Boston, in the county of Suffolk and State of Massachusetts, haveinvented new and usefullmprovements in Mangles, of which the following is a specification.

The nature of the invention, in detail, is described below.

In the accompanying drawings, in which similar lettersof reference indicatelike parts, Figure 1 is an end elevation of my improved mangle. Fig. 2 is a rear elevation of the same. Fig. 3 is a transverse vertical section.

A is the frame of the machine, A the table, and B the box or receptacle holding the goods to be smoothed.

C is the larger roll (covered with feltor similar substance) upon the shaft 0, to which is fixed the gear-wheel D. This roll is made adjustable, so as to press more or less against the ironing-bed H above it in any convenient man- .ner, preferably by having its shaft-bearings adapted by means of the screw-thread b on the vertical shaft 1), actuated by the bevel-gear c d, (to the shaft 6 of the latter of which power is applied,) to be raised and lowered in the slots or openings to. This is substantially the adjustin g mechanism shown in Letters Patent numbered 238,657, granted to me March 8,1881.

The smaller roll E on the shaft E, whose ends rest in adjustable boxes Gr, lies above the ironing-bed H, and is rotated by means of the gear-wheel F, secured to the shaft E and engaged by the gear-wheel D.

H is a metallic reciprocating ironing-bed, guided by means of a pair of rollers, I I, supported in arms J. Each arm J (there being one at each end of the ironing-bed) supports two rollers, l I, one of which is above and one below the ironing-bed H, as shown in Fig. 3. Motion is imparted to the bed H by means of the two rods K, pivoted at K to the ironingbed, and encircling the eccentrics L upon the horizontal shaft L, to which is fixed the gearwheel M. This wheel M, by means of the intermediate gear-wheel, N, is engaged by the small gear-wheel O, fixed to the shaft 0.

Motion having been imparted, by means of the crank P and gear-wheel P, to the wheel D, the rolls 0 E rotate, and the ironing-bed H re- (Model) oiprocates between them. The articles to be smoothed are placed in position-the smaller ones, such as napkins, &c., between the iron ing-bed and roll E, and the larger ones, such as sheets, 850., between the ironing-bed and roll O-and are carried from the box B over table A through the machine. The ironingbed is so geared that when its movement is with the rolls it moves more slowly than the rolls, thus preventing wrinkling, which would ensue if the movements of the bed and rolls were the same, and aidin gin polishing. When its movement is contrary to thatof the rolls of course there is no danger of wrinkling.

Risa sliding platform extending from front to rear of the machine, resting upon the crossbars A of the frame and guided by the bent pins S, which project into the grooves R. Secured to this platform R, at the rear side of the machine, is the guiding-plate T, of the peculiar sh ape shown. The operation of this plate T is as follows: When a large article-such as a sheet, for example-is to be passed between the ironing-bed H andthe large roll 0 the operator (who stands on the side where the box B is placed) pushes the platform R from her .until it is in the position shown in Fig. 3.

Then when the sheet has passed through ironed, of course, on one side only-it falls upon the concave portion T" of the plate T, and is guided back under the roll, when it is seized by the operative, reversed, and the platform It drawn back until the concave portion T nearly touches the roll 0, to whose shape it conforms. The sheet is then passed through the machine to be ironed on the other side, when it drops upon the portion T of the plate T, and is guided off into a receptacle placed behind the machine. Thus this guiding-plate T and platform It save traveling around the machine to obtain an article in order to iron it on its reverse side, or else keeping an extra hand for that purpose.

It is understood, of course, that heat is applied in the ordinary manner to theinterior of 5 and gear D O, the roll E, shaft E, and gearto the sliding platform R, supported in the wheel I, of the curved reciprocating ironingframe of the machine, substantially as and for I0 bed H, rods K, eccentrIics If, shaft L, gear M the purpose set forth. N arms J and rollers a1 supported in the i i 5 frame A, and constructed and arranged sub- JAMES LRAWFORD' stantially as and for the purpose set forth. Witnesses:
