' Arranged-adjacentrorxerendwi thep'frarne lSi isrv thetransverse bar 26*; said bar-being disposed-e intermediate the arms 20 and 2|. Projecting from the transverse bar 26 and secured thereto is the pair of spaced apertured ears 2'! and 28. Pivotally connected to the apertured ears 2'! and 28 by means of the pins 29 and 30, respectively. are the complemental links 3| and 32 which are arranged in spaced, parallel, relation with respect to each other. The ends of the links 3| and 32 are pivoted to the legs 33 and 34, respectively, of the support 35, and secured to the support 35 is the rod 36, said rod being held in side by side relation with respect to the mop handle ID for sliding movement therealong by means of the clamps l1 and I8, and for sliding the rod 36 and supports 35 longitudinally along the mop handle III, the actuating lever 31 is secured to the rod 36.

Secured to each end of the transverse bar 26 is a guide link 38 and 39, the link 38 having one end pivotally connected to the arm 20 of the frame [9, by means of the pin 40, and the link 39 having one end pivotally connected to the arm 2| by means of the pin 4|. Journaled in the other ends of the links 38 and 39 is the shaft 42 and rotatably mounted on the shaft 42 is the upper or first roller 43, coated with rubber or other suitable material. The first roller 43 is positioned on one side of the mop cloth l2, and

positioned on the opposite side of the mop cloth 7 I2 is the second or lower roller 44 rotatably mounted on the shaft 45, the shaft 45 being joumaled in the links 46 which are arranged in spaced, parallel relation on each side of the frame l9 and formed integral with the arms and 21, Figures 4, 5 and 6. The roller 43 is normally biased towards the roller 44 by means of the springs 41 and 48 arranged on opposite sides of the frame l9, the spring 4'! connecting the movable link 39 to the fixed link 45, the coil spring 48 being similarly connected on the other side of the frame l9. 7

The operation of the mop and wringer is as follows: The mop cloth I2 is made fast to the mop cloth holder ll of the mop handle [0 by means of the spring l3 and hand hold [4. With the rollers in the position of Figure 1, the mop cloth is immersed in a pail of water or cleaning fluid.

After the mop cloth l2 has been dipped in water it may be very quickly and easily wrung out by grasping the lever and moving it towards the clamp l1, thus causing the rods 22 and 23 carrying the frame l9 to be moved along the mop. As the frame I9 is moved, the upper and lower rollers 43 and 44 are moved along the mop cloth l2 to thereby squeeze the water from, the cloth I3, the rollers being positioned as shown in Figure 4 at the completion of this step. After the water has been squeezed out of the mop cloth I2, the lever 25 is moved forwardly from the position shown in Figure 4 to the position shown in Figures 5 and 6, such movement causing the links 3| and 32 which are operatively connected to" the transverse bar 26 to pivot the upper roller 43 out of bearing engagement with the mop cloth 12 since the arms 20 and 2| of the frame l9 will be moved forwardly, while the links 31 and 32 of the support 35 have their forward movement stopped by the lever 31 bearing against the clamp [1. With the upper roller 43 in this raised, out of contact position, the levers 25 and 3'! are moved away from the clamp I! to thereby return the frame and wringer assembly to the position of Figure 1, the lever 31 being released as soon as the mop cloth I2 is clear of the rollers, and the mop is ready to be used for mopping purposes. While the mop cloth I2 is being wrung out, the mop will preferably be held in a generally upright position over a mop pail or like receptacle.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.-

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehend by the spirit of the invention as herein described and the scope of the appended claims.

- Having described the invention, what claimed as new is:

In a mop including a handle, a holder, and a mop cloth releasably carried by said holder, the improvement consisting of providing a wringer for squeezing water from said mop cloth, means operatively connected to said handle for actuating said wringer, said wringer comprising a frame having a pair of elongated symmetrical arms, a first pair of spaced links secured to the ends of the arms of said frame, a first rotatable roller arranged in abutting relation with respect to one side of said mop cloth, and carried by said first pair of links, a second frame positioned above said first frame and having legs of shorter length than the arms of said first mentioned frame, a second pair of links pivotally connected to the arms of said first frame, a second roller rotat-.

ably carried by said second pair of links mounted for movement toward and away from the other side of said mop cloth, resilient means embody-.

ing a coil spring connecting the respective first and second pair of links together for biasing said second roller toward said first roller, and means on said handle for moving said rollers away from each other, said means comprising said second frame, and said second pair of links being operatively connected to said second frame.
