Application filed August 2, 1921. Serial No. 489,174.

To all whom it may concern:

Be it known that L WVILLIAM ROBERTSON, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in VVringers, of which the following is a specification.

For many purposes it is desirable to form the wringer frame with as little height as possible. One of the purposes of this invention is to provide a wringer with a pressure mechanism giving the rolls a wide expansion and at the same time forming a comparatively low frame. Other details of the invention will appear from the specification and claims. The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a front elevation of the wringer.

Fig. 2 an end elevation of the wringer.

Fig. 3 a section on the line 3-3 in Fig. 2.

Fig. 4- a sectionon the line 44 in Fig. 2.

Fig. 5 an enlarged view of one of the wringer stiles.

Fig. 6 a top view of one end of the wringer frame.

1 and 2 mark the rolls. These are carried by bearings 3 and 4 respectively, the bear ings being mounted in a guide groove 5 formed in the walls of the guide slot 6 of The stiles are formed prefer-' the stiles 7. ably of cast metal. Cross bars 8 extend across the wringer from stile to stile at a point opposite the lower roll and tie rods 9 extend across the top of the wringer, the rods extending through the perforated ears 7* on the stiles, the rods being provided with shoulders 9 engaging the inner ear and a nut 9 on the outer end clamping the ends of the rods to each stile. A plate 9 extends across each stile bridging the guide slot, the rods 9 extending through this plate and the nuts clamping the platein place. A top bar 10 extends across the top of the wringer, it having the seats 11 resting on the top bearing 3. The top bar is separated intermediate its ends and hinged at 12. One part of the top has a shoulder 13 operating in connection with a latch 14: on the other part normally locking the sections of the top bar in. alinement.

A pressure mechanism is formed as folto the lower arm 20 of the lever and pressing the lower arm outwardly presses the top arm downwardly on the top bar exerting pressure on the rolls. A screw 21extends through the lever against the spring so that the tension may be varied.

The lever 15 is arranged'on the top ba slightly out of position vertically above the 1 point of engagement ofthe bearing 3 with the top bar. As a consequence when the latch 14: is released from the shoulder 13 the top sections of the top bar swing upwardly at the hinge breaking the connection between the end of the lever and the bearing 7 and consequently releasing the pressure on the rolls.

With this construction a comparatively low wringer frame maybe provided. At the same time a spring of sufficient length is formed to give the pressure mechanism the desirable range.

lVhat I claim as new is 1. In a wringer, the combination of a frame; rolls mounted in the frame; pressure mechanism for the rolls comprising a spring extending outwardly from a plane through the axes-of the rolls, and a lever pivotally mounted on the frame having one endsubjected to the act-ion of the spring; and means communicating the pressure from the opposite end of the lever to the rolls com prising a release device adapted to break the communication between the lever and the rolls and release the rolls from the pressure of the spring.

2. In a wring-er the combination of a frame comprising stiles; rolls mounted in the stiles, the upper roll being slidingly mounted; brackets extending from the stiles; bell crank levers pivotally mounted in the brackets; springs extending outwardly from the frame operating on one end of the bell crank levers; and means communicating the pressure of the opposite end of the bell crank levers to the upper roll comprising a release device adapted tohreak the communication between the lever and the roll for releasing the roll from the pressure of the spring. 1 a e 3. In a Wringer, vthe combination of a frame; rolls mounted in the frame pressure mechanism for the rolls comprising a spring extending outwardly from a plane through the axes of the rolls, and a lever communieating pressure from the spring to the rolls; and a release device between the spring and rolls for releasing the rolls, said release device comprising a top bararranged betweenthe rolls and the lever, said top bar being transversely breakable.

In testimony whereof I have hereunto set my hand.

WILLIAM ROBERTSON.
