V IMPROVED CLOTHES-WRINGER.

TO ALL IVI-IOM I'I MAY COWNCERN: l

Be it known thatI, J". lvI. McMASTER, of Rochesteigfin the county of Monroe, and State of New York,

have invented certain new and useful Improvements in Clothes-Wringers; audI do hereby 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 whichi Figure I'is aside elevation of an ordinary,clothes-wringer'with my invention attached.

Figure 2 is a'n end elevation of the sainte. Figure 3 is a face view of the coupling-head and oval bar b. Figure 4 is a top view of one of the clamps C. Similar letters of reference indicate corresponding parts.

Thisinvention relates to that class of clothes-wringers in'which the presser-rollers' are geared together by independent drivers; and it consists mainly in providing an adjustable short shaft, upon which is hung the` wheel or pulley that communicates motion from the driving-wheel or pulley.

To enable others to make and use my invention, I will describe its construction and operation.

I use the ordinary presser-rollers R and R', and any suitable springs S. Those herein shown are made double, from one piece of timber, by cutting out a wedge-shaped piece from the centre ofeach end,- which it is believed will aiord a stronger and more flexible spring than is possible, as heretofore made. The arch or bridge i B and the vertical bar D are slightly recessed, as shown at a, (iig. 1,) to receive the stirrup s, in which the adjustable shaft S has its two axial bearings. The bar D may be locked to the bridge by being notched into it :it the top and bottom, or it may be provided with a lug or foot at each ond to rest against the standard or i upright of the frame. The friction-wheels or pulleys P and I are rigidly attached to the shafts S and G. The

shaft S is made adjustable verticallybyf` means of the set-screw b. `As may be seen, this stirrup also retains the shaft in a horizontal position, or parallel with the driving-shaft. The shaft of the upper roller R is provided A with the coupling-head It, which hasfour lugs c. The armsd projecting from the shaft S, clutch loosely between 1 these lugs, and thereby effect the coupling, and by reason of the space betweenthe arms and the lugs, the upper presser-roller is permitted to make anynecessary amount of change in its relative position, without prodieing any cramping between the parts. The inner face of the clamps C is made V-shaped, horizontally, the V being made very open or flat, as shown in fig. 4. This shape of the clamp face insures an equal bearing at two points horizontally, whether the wringer is attached to a very small'eircle or to a straight surface. This plan aiords all the advantages oi`- the ordinary horizontal spring or circular clamp, and at the same time avoids the objection of the clamping-screws J beingin the way of the clothes which are beingdischarged from the machine.

These clauips may be provided with a dowel or steady-pimp. The friction-wheels or pulleys P and P may he made ofi' rubber, or one or both of them may be made of wood or iron, with a rubber or other elastic band rigidly {ixed to their periphery. The traction face or periphery of these pulleys in either case may bie` roughened if desired, though it would scarcely be necessary.

What I claim as my invention, and desire to secure by Letters Patent, is

I. The employment or use of the friction or traction pulleys, either with or without a rougheued periphery, arranged and operating substantially in the manner and for the purposes herein shown and described.

2. The adjustable shaft S, arranged and operating in connection with the driving-shaft Gr, and rollers R f i and R', und coupling /i and d, substantially as and for the'purposes set-forth. 3. The relative.' arrangement of the two separate side clamps C, provided with ajsuitable dowehp, and

suspending strap g, andwhen they are so made as to have each two separate bearings horizontally, as and for the purposes specified.

J. M. McMASTER.
