is swung and causes its; connected parts, that andihencejforce link 8 5 forward1y-; which in i turn forces presser-board 81 to a proper position whereby to squeeze the mop.- The water oozes out forwardly through slots or recesses 78 hooded by flanges 79, and rearwardly through holes 97. The spring 91 is made of a piece of metal which is capable of bending between its bearings so that if the operator presses the handle further then the presser-board is able to move the resiliency of the spring will permit the excess of movement, that is, compensate for the undue swing of the handle. Said clearance 98 in axle 94 having been previously so disposed with relation to the turning of said axle 94, as to lie in the path of the end of link 85 when said end is forced rearwardly by the pressure of the mop upon the presserboard 81.- Wings 74, 74, are adapted to direct the strain, if any, upon the upper edge of the pail employed.

The remaining figures show modifications of the device. The front piece is represented by 1, and 2 and 3 represents the side pieces which'are secured thereto. A stay-bolt is illustrated by 5 showing double nuts on one end and a head on the other end for securing the

sides

2 and 3 at their free edges. The

side pieces

2 and 3 have depending portions indicated at 7 and 8, respectively, each being provided with a

lug

9 and 10 to engage the edge of the pail, as seen in Fig. 6.

Portions

7 and 8 each have preferably a tip, shown at 12, which-bears against the inner face of the pail aiding in supporting the wringer on the pail.

The presser-board of the wringer is represented by 15 and may be bored with holes 16 for the escape of the water, the same as may be done with the face-board 1 by holes 17. The presser-board 15 is to travel to and fro between the

side pieces

2 and 3. At each end it has downward arm, integral or otherwise, as shown in various ways to hold the presserboard. This may be held in different or in yielding positions, as indicated.

In the form shown in Fig. 8, the portion 7 has two cutouts, as at 21, the bottom of the arm 20 being provided with a headed stud at the point'22 to set into one or the other of these cutouts 21, according to the size of the mop which is'to be pressed, so as to take either a large or a small mop. A shaft 30 is mounted at each end in the

side boards

2 and 3 and provided with a handle 32. Shaft 30 has secured on it the arms 33. At the end of arms 33 are links 34 pivotally mounted thereon, and at the end ofeach link is pivotally connected arm 35 which is connected at its other or remote end to the presserboard 15, being secured as to a cleat 36 bv pin 37. A pin 38 may be placed on the cleajt 36 to limit the upward swing of thearm, 35.

At 40, Fig. 7, is acurved arm pivotally mounted at the outer end of the link 34 and extending through a block 41, Fig. 6, on the arm 33 so that arm 33, a spring 43 being carried by the curved arm and bearing at one end against the free end of the link 34 and at the other end against the block 41, or. the arm by which it is carried.

As seen by reference to Fig. 9, when the lever or handle 32 is swung to the left, the parts assume somewhat such position as shown, and there is a direct movement of the presser-board against the mop as the shaft is turned and the arm 33 pushed backward. In the earlier part of the movement, as shown in Fig. 7, the spring 43 tends to keep the link 34 swung outward from the pressure is applied in the front portion of the movement by reason of the position and strength of spring 43, and this pressure continues until it assumes about the position shown in Fig. 9, or in other words, until the link 34 lies directly in the line of pressure between its connection with the curved arm 35 and the presser-board. l/Vhen the handle is released the tendency of spring 43 will swing the link upward. The

parts may be restored to their normal position by spring 47. Fig. 7, one end of which is secured to the movable parts, as the arm 33, and the other end, as to the side2, the swinging of the handle to compress the mop putting pressure on said spring 47 which returns the parts to their normal position when the handle is free. A modified construction of said spring 43 is shown in Fig. 11 where the spring 45 has each end connected with the swinging the action of the handle in pressing the mop compresses the spring as well. The equivalent of this return spring is shown also at 47 in Fig. 6.

Various modified constructions may be employed by the ordinary mechanic which would still be within the spirit and scope of this invention.
