BJ'ARNE O. THOMPSON, OFCHICAGO, ILLINOIS.

Letters Patent No. 91,794, dated .Time 22, 1869.

The Schedule referred to in these Letters Patent and making prt of the same.

To all whom it 'ma-y concern:

Be it known that I, BJARNF. 0. THOMPSON, ofthe city of Chicago, in the State of' 1llinois,.have invented certain neo7 and useful Improvements in Mangles and Vriugers; and I do declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a rear elevation.

. Figure 2, an outside view of one of the posts and the bottom-support. m

Figure 3, an inside view of one of thep'osts.

Figures 4, 5, (i, 7, details.

To enable others skilled in the art to make and use my invention, 1 proceed to describe the construction oi' the same. r p

' A A B C D represent the frame and supportingpieces, which are constructed in the usual manner.

On the inside, and near the top of the standards, or posts A A', is a long groove, k, fig. 3, in which `the irons G are inserted and moveup and down.

a is an iron plate, secured to these posts over this groove, or recess; but before being fastened thereto, the iron c is placed in proper position, the portion d extending inward, as shown, c heilig wider than the slot, or opening seen at k, iu the plate a.. f

b b' are slots, or openingsiu the posts, through which the `journals of the cylinders are inserted'.

The upper cylinder is supported at each end in the hole n, near the lower ends of the irons c.

The form of this iron c will be seen in figs. 4, 5, 6, being three views of the same. It consists ofa single piece, c d, bent at right angles, the horizontal portion d having a iiange on each side, and a slot, mf, in the bottom. V Y

F is a spring, which may be of wood or metal. The

ends of this spring rest upon d, between the flanges thereon, and a piu, having a head or screw, is inserted in the spring, at or near each end, and on the under side, passing through the slot m, and so arranged as to move therein. v

This spring'can be tightened or loosened by :means of the screw Z, operated by the crank e.

As the spring F is raised, the cylinder E will be also raised, as the spring,r cannot be withdrawn from d in consequence of the screw, or headed pin s.

Ou each end of-each cyliudcigl place a piece of v rubber, G, such as is used upon clothes-wringers, about six inches long, so that this portion of the machine can be used as a clothes-wringer, the remaining part being used as a maugle.

The cylinders are of wood, and I usually make them about two feet nine inches long and about three inches in diameter.

f is the crank for operatingV the mangle, on which is au arm, g, pivoted, which has a projection, i, near the upper end, which 'enters a hole iu the end of the journal upon which the crank is placed, and the rod,`

or arm g, is held in place by the spring li..

When it is desired to remove the orank,'it can be done by pressing back the spring h and arm g, so as to withdrawthe piu 'i from the journal.

Vhat I claim as my invention, is

The construction of the rollers, a. port-ion of each being constructed of India rubber, fora wriuger, and a portion of wood, or other hard material, for a mangle, in combination with the frame and other devices, as arranged and shown.
