IMPROVEMENT IN WRINGiNG-MACHlNES.

The Schedule referred to :in these Letters Patent and part of the same.k

To all whom it may concern Be it known that I, ELBRIDGE G. W. BRTLETT, of the city and county ot' Providence, in the State of Rhode Island, have invented a new and useful Improvement in NVringing-Machines; and I do hereby declare that the following specification, taken in connection with the drawing making a part of thc same, is a full, clear, and exact description thereof.

Figure 1 is a view in perspective of the machine.

Figure 2 is a view of the device for bringing the surfaces of the rollers nearer together.

Figure 3 is a view of a clamp employed in the machine to .attach it to a tub.

In the drawing- Fig. 1, A A are the standards for supporting the squeezing-rollers B B.

The driving gear of the rollers, and the clearerrol-ler C, shown in the drawing, are .fully described in the Letters Iatent granted to me May 24, 1870, and the machine, except i-n the particulars hereinafter specified as constituting the improvements, is the same in principle as many machines for this purpose known to the art.

The improvements which are the subject of this patent relate- First, to a device for bringing the ,surfaccs'of the squeezing-rollers nearer together; and

Second, to a clamp for attaching a machine to a wash-tub.

Ordinarily one or more thumb-screws are employed tocanse the boxes which contain the journals of the upper roller to approach nearer to the boxes of the lower roller, and thus bring the yielding surfaces of the rollers closer together'. I n place of such screw or Iscrews I make use of the hcreinafter-describcd device.

D is a lever, whose fulcruin is at a, in a standard set in the cross-bar E of the frame of the wringer. This lever has a mortise cut through it of sufiicient size to admit the squared shank of the rod F, which latter is heldin guides so that it can be readily moved for a limited distance up or down.

The back side of the shank ofthe rod is furnished with teeth, b, constituting a rack, and with these teeth are engaged thel teeth of a segment of .a pinion, c, into which the hub of the lever D is formed.

A latch, G, is `pivoted to the lever D, as shown, the

the surfaces ot' the squeezing rollers will be brought nearer together, and bc held at such distance apart as the latch, and the catch with which it is engaged, shall allow.

A catch and latch-lever compress, as described, is ou several accounts more convenient than the compressing-screw usually employed, especially in wringing-machines of large size, in the use of which great inequalities in the thickness of the folds of the heavy articles 'of clothing subjected to their action occur. A capacity on the part of the machine to be readily adapted to suoli extreme variations in the thickness of the clothing, without loss of time and without the necessity of stopping the rollers to make the proper adjustment, is highly advantageous.

A further improvement resides in the clamp for securing the washing and wringing-machine to a tub.

It consists in kattaching thepressure-pad or plate to the shank, which the thumb-screw operates, by a joint connection, so that such` clamp can be made. to adapt itself to tubs of any size, 'and whether circular or sqnarein form.

I is a thumb-screw which Works in a collar f.

J, iig. 3, is a nut or hollow shank set in a guide in the standard. lTo this vshank the pad or pressureplate K is hinged at g. It is obvious that by this method of construction the clampis made perfectly self-adj usting to every form and sie of tub'.

What I claim asvmy invention, and desire to secure by Letters Patent, is-

1. A catch and latch-lever compress, substantially as described, in combination with the cross-bar Hand the boxes' of the upper squeezing-roller, as herein specified for the purposes set forth.

2. rlhe thumb-screw I, nut or hollow shank J, and lpressure-pad K, all in combination substantially as described.
