TO ALL WHOM IT MAY CONCERN Be it known that I, R. A. STRATTON, of Philadelphia, Pennsylvania, have invented an Improved Mangle; and I do hereby'declare the following to be a full,'clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists in the combination of three rollers with certain spring standards, which serve the twofoldpurpose of forcing the intermediate roller against the upper and border rollers, and of supporting and affording bearings-for the journals of the three rollers, My invention also consists in the'combination of the said tllree rollers with a shield for directing the clothes in the proper course.

In order to enable others skilled in the art to make and use my invention, construction and operation. On ret'erence to the accompanying drawing,

Figure 1 is a front view of my improved-mangle.

Figure 2, an end view.

Figure 3, a transverse section on the line 1-2, fig. 1; and

Figure 4, a longitudinal section of part of one of the rollers.

Similar letters refer to similar parts throughout the several views.

A is the base of the mangle, and to this base are secured the two frames or feet 13 and B, each of which -is so constructed as to form sockets for the lower end of the two wooden standards D and D, which are perinanently secured to each frame by a bolt, a. On the inside of the opposite standards D D are formed concave recesses for the reception of the journals 6 and bof the rollers E and E, and on the inside of the'standards l) Di are formed similar recesses for the reception of the journals (2 of the roller F. The standards D and D at both ends of the machine are secured together at a point below thejournals of the lowest roller E- by a bolt, f. The peculiar arrangement of the several rollers will be best observed in fig. 3, on reference to which it will be seen that the roller F is somewhat smaller in diameter than the rollers E and E, which are of equal diameters. It is not absolutely necessary, however, that the roller F should be smaller in diameter than the others, although I will now proceed to describe its which forms a part of this specification- I preterit to be so, as it is the drivingdbller; the handled fly-wheel h beingsecured to one of its journal's,

which projects beyond the standards, or an additional shaft maybe used to carry a pinion gearing into a wheel on the projecting journal of the roller F. The peculiar arrangement of the rollers E E and F has for its object the submitting of the clothes to be mangled to the machine in the direction of the red line 2; :v, fig. 3, which is the most convenient arrangement for-the attendant, who has simply to pass the article of olothingbetween the rollers E and F, when it will be directed between the rollers F and E in the manner described hereafter, and fall thence, properly mangled, into any suitable receptacle on the floor or base of the machine. The pressure imparted to the clothes when thus passing between the rollers will depend upon two things: first, on the'diatm etcr of the roller F compared with the distance between the rollers E and E; second, on the pressure imparted by the standards and bolts to force the roller F between the rollers E and E. For instance, if the diameter of the roller F be little greater than the distance between the rollers E and E, but little force need be'exerted on it by the standards and screws f .to obtain the desired pressure outhe clothes. I have found the propertions and arrangement'of the rollers, eiihibited in fig. 3, to be advantageous in practice. In order that the clothes may, after passing bet-ween the rollers E and F, be directed between the rollers F and E, I make use of an endless apron, G, which passes round the rollers E and E, and between these rollers and the roller F; the clothes to be mangled passing between 'thelatter roller and in eontactwith the apron. In order that this apron may not crowd to one end or the other of the roller, and in order'that it may remain stretched and free from creases, Lso stitch the opp'bsite edges that it will be there contracted in length, so as to lap over the ends of the roller as seen at y, fig, 4, this contracting or reefing of the edges effectually preventing any lateral displacement or creasing of the apron, which] although to be preferred for various reasons, may be dispensed with and a permanent shield, m, introduced", as shown in fig. 3, for directing the clothes between the rollers F and E. As the standards I) anrl D are disconnected from the holtsfto their upper ends, they serve as' springsto push the roller F between the rollers E and E, the rigidity and force of these springs depending on the adjustment of the bolts ff, and as these springs, readily yield to slight irregularities in the thickness of the object mangled, the operation of the machine is rendered uniform and easy.

As these standards serve the twofold purpose of supporting or eii'ording bearings for the rollers, and forcing tlie intermediate roller between the upper and lower rollers, and as the usual iveigbts and' springs or other devices used for applying the desired-pressure in ordinary mangles ure dispensed with, it will be evident that my improved mangle possesses the advantagesof simplicity and ,chcapness, while its efliciency is equal to that of more costly machines of this class.

I claim as my invention, and desire to secure by Letters Patent- '1. The combination of therullers E E secured to-the adjustable spring standards D D, aml the roller F secured to the spring standards D, the whole beingconstructed and arranged as and for the purp bs e'set forth.

2. The shield'm, arranged in respect to the rollers as and for the purpose described, In testimony whereof I have signed my name to this specification in the presence of tvi'o subscribing witnesses.
