MOP RINGE Application filed Decemberll, 1930; Serial to. 501,500.

This invention relates to mop wringers. Numerous attempts have been made toprovide a satisfactory wringer which would meet the demands requirements of the public. 5 These attempts have encompassed several types of wringers; one in which the mop is passed between squeezing rollers, another in whichJa mop is twisted, and the third in which water is squeezed from the mop by 10 means of the application of pressure. @f

these three well known types the-lastmentioned is by far the inost BfiCii1lV85 by-areason of the fact that little 'or'no daniage istdoneto the mop by repeated squeezing operiati'ons.. 1

The general aim of the present invention is the provision of improved meansi-n the last named type of wringer for applying a squeezing pressure to twosides'of .the' wringer" by moving a plurality of opposed splatesrtow-ard each other. 1 11+.

One obi'ect is the provision of amopiwringer which is simple'inconstruction;-clurable' in service; effective in operation, and inexpensive to manufacture. a i

The pins 30, which extend inwardly from the plates 28, cooperate with horizontally disposed slots 37 fashioned in cars 38 formed on brackets 39. Slots 40 in the brackets 39 cooperate with the pins 35 andsimilar slots 41 cooperate with pins 42 anchored in the side bracket 10 so as to guide the members 39 in their vertical movement. The lower extremities of the members 39 are provided with arms which extend outwardly and downwardly. Cam slots 43 are formed in the arms in such a manner as to encompass the

pins

22 and 23 formed on the ends of the plates 19 and projected throughthe

slots

24 and 25 in the end plates 10. I

' The bar 26 is provided with a handle socket 44 adapted to receive and retain a handle 45 in any provided manner. When the handle 45 is swung from the position shown in Fig. 3 to that shown in Fig. 4 the plates 28, carried by the end of the bar 26, are rotated and the pins 29 are swungrearwardly and upwardly while the pins 30 are swung forwardly and downwardly. As previously described, the pins 29 and 30 cooperate with slots 31 and slots 27 respectively in the members 33 and members 39. As the pins 29 are drawn rearwardly and upwardly they impart movement to the members 33, and in so doing raise the bottom member 15-of the mop basket. Simultaneously with this motion the'pins 30, which are acting in the slots 37, move the members 39 downwardly and in so doing impart to the pins 22 an inward movement along the horizontally disposed portion of the slots 43 and the downwardly inclined portion of the slots 24. As the members 39 start their downward movement'the pins 23'remain in the horizontally disposed upper ends of the slots 25 until such time as the extremities of the pins 23 engage the horizontal portion of the slot '43. At this time the follower plates l9 have reached a substantially horizontal position. Continued pressure will force the plates 19 downwardly in opposition to the upwardmovement of the member 15. It will thus be noted that a'mop which has been positioned within the receptacle will be exposed to pressure of the plates 19 and member'15 simultaneously and by reason of this quickly and forcibly e ected from'the'mop.

When the mop has been exposed to sufii- 'cient pressure to free it of all excess water,

the handle 45 may be swung back to the posiwater by the simple and easy manipulation of handle45. The construction of the wringer is such that ready application and removal of the wringer is possible by reason of the fact that the interior of the mop receiver isfree from moving parts. The several guide and cam slots formed in the end plates of the wringer serve to permit the application of the, actuating means to the outer walls of the plates in a manner which facilitates their'free and unimpaired movement. By virtue of the fact that all of the actuating means are mounted on the end plates, itis possible to provide a small and compact device of unusual strength and durability.

Various changes may be made in the embodiment of the invention hereinabove specifically described without departing from or sacrificing any of the advantages of the invention as defined in the appended claims.
