HENRY A. WEBSTER, OF MILFORD, MASSACHUSETTS, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO GEORGE E. W. LUEHRMAN, OF ST. LOUIS, MISSOURI.

WBINGER.

Application led July 29, 1920.

Toallwhomz'tmay concern: y

Be it known that I, HENRY A. WEBSTER, a citizen of the United States, residing at Milford, Worcester County, Massachusetts, have invented a new and useful Wringer, of which the following is a specification.

This invention relates to wringers.and has special reference to a mechanism for quickly releasing the pressure devices of the wringer rolls, whereby the pressure devices may be quickly released whenever desired, as in case of an emergency.

An object of the invention is to provide a wringer with equipment cooperating with the pressure devices for the wringer rolls, whereby the pressure may be quickly released in ya more convenient manner from either side of the wringer than is possiblel in wringers of ordinary construction.

Other objects of the invention will appear from the following description in which reference is made to the drawing showing a preferred embodiment of the invention, and in which- 1 Fig. 1 is` a plan view of a wringer equipped with my present invention.

Fig. 2 is a side elevation thereof with parts of the wringer frame members in section, and with the wringer rolls pressed together.

Fig. 3 is a similar elevation showing the pressure devices released and in position in which they do not press the rolls together.

As shown, my invention is embodied in a wringer `comprising a frame composed of a vertical member 1 and a cooperating vertical member 2, said vertical members being joined by connections 3. The lower wringer roll 4 is supported on and may be driven by power a plied to a shaft 5 at one end thereof. he opposite end of the shaft 5 is equi ped with a pinion 6 meshing with and riving a inlon 7 which is secured to the shaft 8 o the upper roll 9 of the wringer. The shaft 8 of the upper roll is journaled for rotation in vertically movable blocks 10 supported in the vertical end members 1 and 2 of the vertical frame. The roll 9 is pressed to a position of cooperating relationship with the roll 4 by an appropriately shaped leaf spring 11 held in position by the vertical end members 1 4 Serial No. 398,703.

and 2 of the wringer frame andacting zltfogainst the upper ends of the bearing blocks spring 11 is engaged-by a pressure bar 12 whose ends are guided for movement by the frame members 1 and 2. By forcing the pressure bar 12 downwardly the spring 11 may be tensioned so to press the roll 9 toward the roll 4, but permitting vertical movement of the roll 9 against the resistance of the spring 11 as re uired when the Wringer is in use and clot is being passed between the rolls.

A 'bracket 13 is in connection with the upper end of the vertical frame member 1 and has a transverse shoulder 14 under which one end of a cross bar 15 is engaged. The upper end of the vertical frame member 2 1s provided with a bracket 16 having a recess 17 arranged to receive one end of a sliding bar 18which is in connection with the cross bar 15.' A slot 19 is formed in the sliding bar 18 through which the stem of a set screw 20 passes, said sliding bar being provided with an additional slot 21 receiv` ing a screw 22 by which said bar 18 is held in position upon the cross bar 15. This construction permits movement of the sliding bar 18 to and from latched connection with the bracket 16. When the Vsliding bar 18 is in latched connection with the bracket 16 the set screw 2O at one end of the bar 15 and the set screw 23 at the opposite end of said bar may be adjusted to press the pressure bar 1 2 downwardly as required to tension the spring 11 and presses the roll 9 toward the roll 4. B roper manipulation and adjustment o t e set screws 20 and 23 any desired degree of tension may be lplaced in the spring` 11.

push plate or mk 24 has one end pivoted at 25 to the sliding bar 18 and has its opposite end ivoted at 26 to one end of a link or ush p ate 27. The opposite end of the lin or plate 27 is connected to the cross bar 15 by a pivot 28490 that by adjustin said plates 24 and 27 in straight or allned position as shown in Fig. 1, the sliding plate 18 will be held in latched connection with the bracket 16. By breakin the toggle formed by said plates 24 and 2 the sliding plate 18 will be released from its The arcuate central portion of theI The spring 32 is of the expansion type and` has one end bearing against one of the end walls of the recess 31 and the opposite end bearing against a depending projection 33' on the sliding bar 18 and acts normally to press the bar 18 outwardly beyond the end of the cross bar 15 into latched engagement with the bracket 16.

The toggle action of the plates 24 and 2T results from the fact that the pivot 28 is stationary so that when the toggle is broken the bar 18 will be unlatched or disengaged :from the bracket 16; and when the toggle is straightened the sliding bar 18 will be moved outwardly into latched engagement with said bracket.

I am aware that the specific construction and arrangement may be varied without departing from the principle and nature of the invention.

I do not restrict myself to unessential features, but what I claim and desire to secure by Letters Patent, is

1. In a wringer comprising the combination of a frame, a lower stationary and an upper movable roller mounted therein, a spring exerting pressure on the upper roller, a cross-bar mounted in said frame and adapted to receive the pressure' of said spring, a bar slidably mounted on the top of said cross-bar and adapted to engage under a keeper on the frame at its free end, and a pair of push plates having operating surfaces disposed on opposite sides of said wringer frame, and beingpivotally connected` one of said push plates being connected at its inner end to said cross-bar and the other at its inner end to the end of said slid ably mounted bar, whereby when the free end of either of said push plates is pressed inward, said bar will be drawn inward and release its free end from engagement with said keeper and thus releaseone end of sa1d cross-bar and relieve the pressure of the spring on said upper roller.

2. A wringer comprising, in combination with the upper movable roller of the wringer, means including a cross-bar for holding said upper roller under pressure in yielding contact with a lower stationary roller, a rigid bracket engaged by one end of said crossbar. a latch holding said crossbar at the opposite end, a push plate operatively connected with said cross-bar and latch for horizontal movement, a spring tending normally to press said latch outward and to hold the push plate in operative position` said push plate being adapted, when pushed inward, to release the latch and therebyY free one end of the cross-bar to release the pressure on said upper roller, leaving the other end of said cross-bar in engagement with said rigid bracket.

3. A wringer, com rising a frame, alower A roll mounted in the rame, movable bearing blocks mounted in the frame, an upper roll controlled b said blocks, a spring pressing upon said b ocks to hold the upper roll in cooperative relationship with the lower roll, a cross bar mounted in the frame, a device between said bar and said spring for pressing upon said spring, a bracket in connection with said frame, a sliding latch bar carried by said cross-bar for engagement with said bracket, and a pair of pivotally con nected push plates, one of which is pivoted to said cross bar and the other of which is pivoted to said latch bar, whereby when the end of either of said plates is moved inwardly, said latch bar will be moved from engagement with said bracket and thus release one end ot said cross bar and relieve the pressure upon said upper roll.

4. A wringer'comprisin'g, in combination with the upper movable roller of the wringer, means including a rigid cross-bar extending from end to end of the wringer, for holding the upper roller under pressure in yielding contact with the lower stationary roller, a standard carrying a' keeper, a latch movably mounted on the cross-bar for engaging the keeper for holding the cross-bar down at one end, and a pair of push plates projectin out respectively beyond the side faces o the cross-bar, supported on the cross-bar so as to move in a substantially horizontal plane toward the cross-bar, said push plates having a connection with the latch for sliding the latch to release the same when either push A plate is moved toward the cross-bar.

5. wringer, comprisin in combination, a spring-pressed upper rol er, a rigid crossbar receiving the spring pressure, a frame, a latch detachably holdmg one end oflthe cross-bar, and an actuating device projecting in a substantially horizontal direction beyond both of the side faces of the cross bar and movably mounted on the cross bar so that it can be operated by ones hand when held on either side of the cross bar by a substantially horizontal movement toward the bar to move the latch and release the same, and thereby relieve the pressure on said upper roller.

6. In a wringer, the combination of a spring-pressed upper roller, a pair of stand` ards, a rigid cross-bar disposed between said standards and receiving 'the spring pressure,
