'lmpnovnn MANGLE.

lhechedulereferred tojnthes'eLett-ers Patent and making part of the same.

To whom tt may concern: v

Be it known lthat I, NrcoLoUs SoDERsTRoM, of Chicago, in the county of Cook, andpState of lllinois, have invented a new and useful Improvement in Mangles; and I do declare that the following is atrue and accurate description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, and being a part of this speci@` tication, in Which- Figure 1 is a front view of my invention, partly in:

section, and

Figure 2 is an end view. e Like lettersindicate like parts in each figure. The nature of this invention relates to an improvement in mangles; and consists in the peculiararrange# nient ofthe rollers one above'the other, working upon proper friction-wheels, the whole being regulated by screw from the top.

Bytbeuse of spiral and India-rubberspring's, a great degree of elasticity is given to the pressure of .the rollers, whereby clothes are smoothed uniformly,

and by the saine means a much greater pressure may be employedwithout danger of tearing clothes thanl by ordinary methods, in consequence of which the work of mangling is performed more nicely.

In this device, also, such a pressure may be brought upon the rollers that the clothing, which is rst wound around the central roller, detached for that purpose, may, by the use of the friction-wheels, enabling motion .to be given to the rollers under very great pressure, be smoothed by a few revolutions without nnwinding the clothes from the roller, as it is usually done, and iu this way the work is performed more expeditiously than by other methods.

A, in the drawings, represents a propefframe, into which is placed the mechanism hereinafter described.

B are rubber springs, surmounted by blocks, which carry the friction-wheels C.

D is the lower smoothing-roller, which rotates freely upon the same. v

E are coil-springs, suitably attached to the frame, and support the blocks and frictionfwhecls F, which sameform bearings for the outer ends of the shaft of the roller G, said shaft being provided at either end with .crank-handles H.

This roller G r can be removed-from the tachine at will. s v

J is the upper smoothing-roller, whose bearings are at K, in any suitable journals or boxes, which are secured to the sliding block L. p p

M are stationary blocks, which .support the spiral springs N, that are surmounted by the blocks O, the whole -being connected by proper rods.

I is a block, upon the under side of `which are attached the friction-wheels It, which same are kept.' in contact with the periphery of the roller J, bythe rubber spring x, between the blocks P and the follower of the screw S, the tension of the springs and the pressure exerted on the fabric by the rollsbeing regulated by said screw.

T.are table-leaves, hinged to the frame A. l

To operatev this invention, remove the roller G from. the frame, and wind upon it the article to -be smoothed. Then Iplace it in its proper position, as

lshown, and by a few revolutions of the rolls, the article being smoothed is ready to be removed.

What I claim as my invention, and desire to secure by'Letters Patent, is-

The combination of the roller J, provided with bearings K, sliding block L, spiral springs N, stationary block M, block O, screw S, India-rubber springs x, block AP, andfriction-wheels' R, with the roller G, provided at either end with crank-handles H, and rotating upon friction-wheels F, and with the roller D pivoted in bearings, which support friction-wheels F, and rest upon spiral springs E, which in turn rest upon a suitable block, and rotating upon friction-wheels C, pivoted upon a suitable block, resting upon India-rubber springs B, which in turn rest upon a suitable block, and with .the .hinged table-leaves T, all in connection with frame-A, constructed and arranged as and for the purposes above set forth.
