H UNITED STATES PATENT GEEICE.

DANIEL M. HARRIS AND SEWINGTON S. BURNET, OF SALEM, MASSACHUSETTS. i

lMPRovED CLOTH Es-WRINGER.

Specification forming part of Letters Patent No. 35,234, dated May 13, 1862.

To all whom it may concern:

Be it known that we, DANIEL M. HARRIS and SEWINGTON S. BURNET, both of Salem, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Clothes-Vringers, of which the following is afull and exact description ofthe construction and operation of the same, refer ence being had to the annexed drawings, makr ing a part of this specification, in whichm i the brace b, which passes through each standard, and is fastened at each end by pins.' j` In these standards ct a, at o and o', Fig.'2`, are boxes, in which the bearings of rolls c c revolve, o being slotted vertically to allow the rolls to open or be brought closer together, as may be required, in passing through goods of Vdifferent thickness. Therolls c c are made of rings cut from vulcanized-rubber packing,

in` form as shown in Fig. 3, and slipped upon the shafts and cemented as they are put on.

Ve are aware that rubber rolls have been made and used for some time. Therefore we do not claim to be the inventors of rolls for this purpose, but of an improvement in putting the rubber on to insure adhesion to the shaft and `to make them firmer and more elastic. As rolls are now used they are made of rubber tubing from seven to ten inches in length and the iron shaft forced into them. lVhatever substance is put on the shaft to :make the roll adhere is scraped off by the rubber in forcing the shaft into it. This difficulty is overcome by making the rolls of the rings and cementing each piece as it is put on, thereby preventing the possibility of the roll turning upon the shaft and making the roll more firm and elastic.

The strap e clasps each end of the shaft of -roll c', and is kept in place by pins f f. The

strap e is then connected with clutch g by a rod, h, which has a screw or thread cut on the lower end, to which is fitted a thumb-nut, t'. The top of the clutch g projects out from the tub to allow the rubberspring to work freely, the spring allowing the rolls c c to accommodate themselves to anyv thickness of goods. Turning the thumb-nut against the spring j serves the double purpose of fastening the machine to the tub and giving to the rolls any required pressure.

Ih at we claim, and desire to secure by Letters Patent as our invention, is`

The combination and arrangement, in a.
