IMPROVED CLOTHES- Speeiiicaton forming part of Letters Patent No. 36,2 IS, dated .T0 (LZZ whom it may concern.-

Be itknown that l, WILLIAM JosLIN, of Cleveland, in the county of Cuyahoga and State of s reference marked thereon, making part of this specification.

The nature of my invention consists in a simple arrangement oflevers and sp rings for pressing the rubber rollers together, and in the employment of a double right and left hand circular inclined plane or section of a doublethrkgead screw for holding the machine upon the tu Figure 1 is a front elevation of myimproved wringing-machine. Fig. 2 is an inside end elevation. Fig. 3 is atop view of the same. Fig. 4 is a view edgewise of one of the double circular inclined planes. The red lines represent a face view.

A and A2 in Fig. l are the ends or standards, each having jaws, between which the tub passes when fastened to it, as shown byK and K2 in Fig. 2.

B and B2 are the rubber rollers, between which the clothes pass in the operation of wringing. l

O and O2 are crooked or somewhat S -shaped levers, being fastened to the standards by means of pins in the ears d and d2 on the out side of the standards A and A2 and working parallel with the rollers B and B2.

D andD2 are bars or rods which hold the ends or standards A and A2 firmly in their position.

E and E2 are caps or boxes (shown by red lines) resting upon the tops of the axis ofthe upper roller, B. 'Ihe tops of the caps or boxes upon which the leversO and O2 rest are rounded, so that the levers may work or rise and fall with ease. The bottom of the cap E and the bottom of the cap E2 are made concave, to fit the pins or axis of the upper roller, B, as shown at E2 in Fig. 2. rlhe caps E and E2 workin vertical slots, as shown at E and E2 in the top View of Fig. 3.

F and F2 in Fig. 1 are loopform rubber springs. The loopspring F is passed under the lever C, toward the cap E, and over thetop ofthe small end of the lever O2. A The spring F is adj usted to make more or less pressure on wRiNGiNG MACHINE.

the roller B by moving it in the notches made in the bottom of the lever C and notches made in the top of the lever C2. The spring F2 is attached to the opposite ends of the levers G and O2 and adj usted by the notches on the bottom of the lever O2 and the notches on the top of lever C in the same manner as the spring F. Metallic springs may be applied and adjusted moving the springs F and F2 toward the center of the levers C and C2the pressure is diminished, so that any desired pressure may be produced with very little trouble. rangement of levers and springs the pressure because the springs move up and down with the levers, and the pressuredoes not increase as fast as if one end of the springs were fastened to some stationary part of the machine. The difference of pressure upon a thick or thin article seems to be the difference between the spaces moved through by the notches on the bottom of the levers C and C2 and the notches on the top of thelevers O and O2. It the springs F and F2 are placed in the notches indicated by the red lines V and V2, when the notches in the bottom of the levers C and C2 move up on the curved lines X and X2 to the points O and O2 the notches on the top of the levers C -and W2 to the points S and S2, thereby causing the springs V and V2 to expand one-half less than they would have expanded if the lower ary part of the machine. It will now be seen that the expansion or pull of the spring V is up on the lever O and down on the lever G2, and the expansion or pull of the springV2 is up on the lever O2 and down on the lever O, thereby causing nearly the same pressure on a thick or thin article when passed'bet'ween the rollers B and B2, which is al result in mechanics very much desired by spring and lever pressure. I have said the difference of pressure upon a thick or thin article seems to be the di'erence between the spaces moved through by the notches on the levers. This would be true if the springs did not pull up on the levers; but the springs, pulling up on the levers aswell as down, produce nearly an equal pressure, as above stated, the thickest article receiving the greatest pressure.

K and K2 in Fig. 2 are thejaws which hold in the same manner as the rubber springs. By

By this aris nearly the same with a thick or thin article, l

and O2 will have moved on the curved lines W2,

end of'the springs were attached to a station' 2 seais the machine upon the tub. a and a2 andb and b2 are the four sides of a toothed mortisein the jaw K2, inrwhich the double right-hand circular incline planes move. G2 is the double righthand circular incline planes or section of a double thread-screw with a pin or shaft passing through the center, with the handle H2 at right angles with the shaft. The shaft passes through the center of sides b and 1120i' the 1ortise. The incline planesare fastened to the shaft by means of a small pin. ain the top of the mortise and a2 in the bottom of the mor` tise are cogs or teeth against which the circular incline planes act. When the handles H and H2 are turned toward the center of the machine, asin Figs. l and 3, the inclines act against the outside or front of the cogs a. and a2 in Fig. 2, thereby causing the center of the inclines to move against thev front side, b2, of the mortise, carrying the shaft and handle H2 with it, thus holding the handles H and H2in the position 4shown in Figs. 1 and 3. The

double circular incline planes G in Figs. `l and 3 are left-handed, and the double circular incline planes G2 in Figs. 1 and 3 are righthanded. When the handles H and H2 are moved out, as indicated by the arrows in Fig. l, the inclines come in contact with the insides or backs of the cogs a and a2and cause the circular inclines, shafts, and handles to move in toward the jaw K, as shown by the red lines in Figs. 2 and 3, thereby holding the machine to the tub by pressing the shafts or pins against it by means of the double right and left hand circular incline planes G and G2, cogs a andA a2, andhandles H and H2 in Figs. 1, 2, and 3.

The perfection and simplicity of this arrange* ment will be readily seen. When the machine is fast on the tub, the handles arein the position indicated by the red lines Hand H2in Figs. 1, 2, and 3. When the machine is takenof' from the tub, the handles are turned up and in toward the center H and H2, Fig.1,'and there remain until placed upon the tub again, thus keeping the pins or shafts outof the way when the machine is put again on the tub. The machine is fastened to any-sized tub with less than a revolution of the right and'left` hand circular inclines, thereby bringing the handles H and H2 on the outside of the machine, out of the way of the clothing as it passes from the rollers to the basket after being Wrung.` The same effect may be produced by one circular incline on cach shaft, but not with the perfection of the double circular incline planes. The left-hand circular incline planes, G, work in a mortise, the same asthat described in Fig. 2. 4

After thus describing my invention, what I desire to secure by Letters Patent is- 1. The springs Fand F2, acting upon the levers C and G2, as above described.

2. The right and left'hand circular incline planes G and G2, .the toothed mortise a and a2 b and b2, and the shafts and handles H and H2, the parts being constructed and operated substantially in the manner and for the purpose set forth.
