SPECIFICATION forming part of Letters Patent No. 341,819, dated May 11, 1886.

Application filed March 23, 1885.

To all whom it may concern.-

Be it known that I, CHARLES K. Srnvsov, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Clothes-VVringei-s; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

The object of this invention is to improve clothes-wringers of the general charactershown in the drawings by relieving their elastic rollers from the powerful pressure of the springs during such time as the machine is not in use.

The drawings represent a wringer provided with my improvements, Figure 1 being a perspective view of the machine with part cut away. Figs. 2 and 8 are vertical sections through the roller-journals taken between the guard-plates and the roller ends, the position of the rollers being indicated in dotted lines and the clamps shown as when respectively applying and releasing the spring-pressure. Fig. 4 is a detail.

A and B are the rollers, normally pressed into close contact by the springs O, in the ends of which they have their bearings. This pressure, sufficient to express the water from articles passed between the rollers, is by my improvement relaxed when the machine is not in use, thus avoiding any tendency to flatten the rollers. The springs are connected by the cross-bar D, and the usual swivelingclamps E are employed, as well as the vertical guards G, through which the journals A and B of the rollers project, the lower aperture being a slot. I make use of these parts of the ma chine, essential to its ordinary use, and by a slight projection on the guards and the addition of a single light casting at each end of the machine Iforce the roller-shafts farenough apart to relieve the excessive pressure.

The castings referred to are the wedgesha-ped pieces H, each having a triangular slot through it, and each slipped upon One end of the cross-bar D, the outer edge of which fits loosely into one of the angles of the triangular slot. These slots are broadest at their inner ends to permit the castings H to be tilted slightly, or have a vertical movement with relation to the inner edge of the bar D equal to-the width of the slots, as indicated in the drawings, Figs. 2, 3, and 4.

The inner end of the casting H engages with Serial No. 159,874. (No model.)

C and cross-bar D, as usual in this class of wringers. The clamps may thus swing about on their axes, and when thus swung inwardly toward each other the shoulder e of each clamp strikes the under side of the wedgeshaped casting Hand gradually lifts its inner edge. This lifting movement is permitted by reason of the triangular slot through which the crossbar D passes, and it serves to separate the rollers, since the crossbar and lower ends of the springs are held down by the journals of the clamps, while the castings H, guards G, and roller A are forced up (against the spring-pressure) by the swinging of the clamp-shoulders 6 under the wedge-shaped castings H, which tilt or tip upwardly, the outer edge of the cross-bar being their center of motion. The pressure thus relaxed by swinging the clamps inwardly and spreading the C-springs is at once restored by swinging the clamps outwardly into position to fit on the edge of the tub, so that there is no liability of failure to apply the pressure when the machine is in condition for use.

For the purpose of releasing the pressure on the rollers, the castings H need not project but slightly beyond the bar D, but they may be prolonged, as at L, and formed with recesses in their inner faces to receive a thin board, M. or. an equivalent sheet of other material, as a clothes-guide, on which the wrung pieces are received, and from which they are delivered to another tub or a basket.

I claim as my invention- The rollers A B, springs C, cross-bar D, clothes-guards G, and swivel-clamps E, in combination with the wedge-shaped pieces H, mounted loosely on the crossbar and adapted to engage with the clothes'guards and to be actuated by the swivel-clamps, substantially as and for the purpose set forth.

' In testimony whereof I hereto affix my signature in presence of two witnesses.
