MELVIN NEWTON LOVELL, OF ERIE, PENNSYLVANIA, ASSIGNOR TO THE LOVELL MANUFACTURING COMPANY, LIMITED, OF SAME PLACE.

CLOTH ES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 450,080, dated April 7, 1 891.

Application filed December 19, 1390. Serial No. 375,195- (No model.)

To all whom it may concern:

Be it known that I, MELVIN NEWTON Lov- ELL, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Olothes-Wringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make .and use the same.

This invention relates to clothes-wringing machines, and particularly to that type of clothes-wringers in which the expressing-rolls are held within the ends of C-formed springs, which give to the rolls their expressing-power; and it consists in certain improvements in the construction thereof, as will be hereinafter fully set forth, and pointed out in the claims.

The object of the invention is to provide clothes-wringers of the type herein named with anti-friction roller-bearings.

In the accompanying drawings my invention is illustrated as follows:

Figure 1. is an elevation View of one end of a clothes-wringer of the type above named with myimprovements thereon. Fig. 2 is avertical section view taken on the line as w' in Fig. 1.

In the type of clothes-wringer shown, as commonly constructed, when the springs are made of steel, so far as I am aware, the journal-bearings of the roll-shafts are formed on the ends of the springs by forging thereon a half-box, in which the roll-shafts lie. The construction and finish are crude, and the machines when in use run very hard, and the wear on the journals is great. I obviate these ojections by providing the journals with antifriction bearings; but in order to adapt such machine to receive and retain such bearings certain new and improved details of construction are required, and these constitute the essence of my invention. The construction shown in the accompanying drawings is as follows:

A A are roll-shafts; A A, the rolls; B, a metal shield, and C the springs. These parts are made substantially as in all wringers of this type, except a peculiar formation given to the spring at its ends to form a seat 0 for holding the roller-bearing case in place.

The anti-friction roller-bearings consist of a cylindrical case D, with fixed end rings F and rollers E. The cylindrical case D is made of common tubing properly finished on the inside to form a surface for the rollers E and seats for the end rings, which are held in place by turning the ends of the case down over them. The ends of the springs C are formed with sufficiently large curves to form proper seats 0 to receive the roller-bearing cases, and, if desired, there is formed on the edges of the seats 0 flanges c to hold the bearing-cases from longitudinal movement.

The frictional contact of the outer surface of the cylinder D and the inner surface of the seats 0' on the spring ends prevent the bearing-cases from turning ordinarily; but by prying the spring apart enough to loosen the bearings, they can be turned so as to change the point of greatest wear when desired.

I am aware of the construction shown in Letters Patent No. 275,165, granted to J. E. Donovan, in which anti-friction roller-bearings are applied to a clothes wringer having C-formed springs formed of wood, andI therefore do not claim, broadly, the application of such bearings to such wringers; but it will be observed that the Donovan device does,
