E. S. HOW'ELL, OF HOPE, NEW JERSEY.

IMPROVE!) WRINGING-MACHINE.

Specification forming part of Letters Patent No. 42,4186, dated April 2G, 1864.

To @ZZ whom it may concern: y

Be it known that I, E. S. HOWELL, of Hope, in the county of Tarren and State of New Jersey, have invented certain new and useful Im provementsin Clothes-VVringin g Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference bein g had to the accompanyingdrawings, making a part of this specification, in which- Figure I is a side view of my invention, partly in section; Fig. 2, an end view of the same, partly in section.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to certain improvements in that class of clothes-wringing machines in which pressure rollers are employed. The invention consists in a novel and improved means for graduating the pressure of the rollers so that the machine may be readily adapted for wringing different kinds of clothes,- and it also consists in an improved means employed for securing the machine to the tub as hereinafter fully set forth.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

The frame of the machine is composed of two uprights or standards, a c having boards or plates b b attached to two opposite sides of them. These uprights or standards a a have each an oblong' slot, c, made longitudinally in them, and in the lower ends of these slots the journals d of the lower roller, A, are fitted and allowed to rotate freely. In these same slots c there are placed boxes or bearings c e,

' one in each, in which the journals ffof the upper roller, B, are fitted and allowed to rotate freely. 'Ihese boxes e c are allowed to slide freely up and down in the slots c c, and within said slots above the boxes c e there are tted two wedges, G O, one being over the other and in opposite or reverse positions, as shown clearly in Fig. 1. rIhese wedges are allowed to slide freely in the slots c c, and the lower wedge rests or bears upon the upper ends of the boxes e e,while the upper surface of the up per wedge, C, bears against a bar, D, the ends of which are also fitted in the slots c c, so that they may slide therein.

E is a spring, which may be constructed of a flat steel bar bent or curved in semi-elliptical form, and having its ends fitted in the slots c c above the bur D, the center of the spring bearing upon the center of the bar D. The ends of the spring E bear against the upper edges of the slots c c, and the convex side of the spring, which is its lower surface, bears against the bar D, as shown clearly in Fig. 1.

F is a lever, which is fitted and works on a fulcrum-pin,j", and is connected to the Wed ges C C, by means of pins g g, which are attached one to each wedge, and are tted in oblong longitudinal slots "h 7L, made in the lever F, the pins g being at opposite sides of the fulcrum-pin f. l

By this arrangement it will be seen that by moving the lever F the two wedges (.l C will be moved simultaneously in opposite directions, and the upper roller, B, made to bear with a greater cr less pressure on the clothes, as may be desired, and by this very simple adjustment of the lever the machine adapted for wringing coarse or ne clothes.

I would remark that the spring E may be dispensed with, but I prefer to use it, as it admits of the upper roller, B, havinga yielding movement, which is desirable in most cases.

i G G represent two upright bars which are connected by a cross-bar, H. These uprights have each an oblong slot, fi, made in them, and similar slots are made through the barH in line with the slots t'. Through these slots screws I pass into the standards a a of the frame of the machine, said screws connecting the uprights G G to the frame, and at the same time admitting of said upri ghts working back and forth in planes at right angles with the machine. The parts of the uprights G G below the screws I form, in connection with the lower parts of the standards c a., a clamp to secure the machine to the tub. The inner side or surface of the upright- G, is made of beveled or inclined form, gradually decreas,L ing in thickness from a point just above the bar H to its upper end, and the inner side or surface of the upright G is beveled in a reverse direction. (See Fig. 2.)

J is a lever, which is fitted on the same fulcrum-pin f as the lever F. This lever J,

works between the nprights G G and the side of the machine, and by depressing or forcing down one end of said lever the upper parts ofthe uprights G G will be forced outythe upper Vends of both upriglits simultaneously.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The two wedges C C, placed one over the other, connected with a lever, F, and arranged relatively with the roller B, and With-or without the spring E, to operate substantially as and for the purpose herein set forth.

2. The uprights G G', beveled at their inner sides, and connected to the frame of the machine, as shown, in combination with the lever J, all arranged to operate substantially in the manner, as and for the purpose herein set forth.
