" London, England kMy .invention relates toimprovements in mops randtheobject of the invention is to devise a mop Y whichgwill not `onlybe efficientv and not liable togetfputof order lire; nary pail and ybut will dispense with the' ordif t vthe Ainconvenience of the use thereof. Y, Y Y

Aygfurther VObjectis*toco-nstruct the mop so that all the parts are enclosed and not liable Ito be deleteriously affected lor displaced when in 1156! l A still further object is 'to dispense entirely with'the useof the vhands in wringingthe mop.

To effect these objects my invention consists 'j of a suitable frame, wringing rollers journalled therein and coacting to wringjthe cloth, one of ltherollers having the spindle thereof journalled 'l' ,in suitable bearings extending into hollow recesses in the frame and provided Q a brush holder with pressure springs, located at the bottom side of the frame and a brush held thereinall the parts inaftermore particularly explained.

'I is the mainframe of my mop which is sub# 4stantially rectangular and is Vprovided. with a socket 2 for the reception of the operating handle.

The frame I at each end is provided with recesses located the bearings v4, 4 having Application April 15, 1936,

` 1v claim. `V(crjwfne) being arranged and constructed in detail as here- Fig. 4 is a -side viewshowing the r'nopwhenthev vfrom the top of the mop y Y' Therecesses 3, 3 are closed-at their upper ends vby the plates I Iwhich iitvinto dove-tailed grooves'` I2 in `the top of the frame Il. The .rinner end-of the plate I I is narrow and is providedlwith a teat r'I3 which may be raised slightlyv byinserting the"- nger' into the notchV I4'fwhereupon theplate I If?V Vmaybe -slid outwardly when -desired 'and 'removed--l so as to uncover the outer ends of Vthe recesses 3` should it be desired to get-at the bearings 4. I4 is the lower roller which is provided with a .plurality of small projections l5 which are designed to coact with recesses I 6 inthe upper roller 8. The lower roller I4 is provided with a. square orifice I 5' extending therethrough. I6 is the spindle of the lower roller, one end of which extends into the frame I and has a square boss I1 at the end. The spindle I6 is provided at the opposite end with a square portion I8 which is with a crank handle I9, having at the outer end thereof fan arm provided Vwith a handle 2 I. The arm 20 is pivoted at the end of the crank arm 'l as indicated so that it may be swung, when not in use, between the clips 22 secured at the top endv of the frame. Y

vrThe crank arm and the spindle are preferably made in one piece and thereby any liability of the crank arm being lost is obviated. The frame l has 'an enlarged opening 23 substantially rectangular so that the spindle vwith the square endsmay be inserted andtplaced in position readily.V The spindle I6 and lower roller I4 are held in position by the pressure of the upper Frank Mullett, Toronto, OntariaCanada, assign-VA orgo'f one-sixth to Mary `Marguerite Cooling,

l'formed integralwith the Vspindle and provided t roller 8, such pressure being produced by the 'i springs 6, see Figs. 2 and 8.

24 is the mopwhich extends between the. rollers 8 and. VIll and is preferably inthe form of any endless belt, see Figs. 3 and 5, extending bev tween the rollers and the bottom of the mop' frame, which lit will be seen has a row of corru'# gations 25 designed to grip into the mopv itself and hold it in position,that is to say, not allow it to move too easily.

When'the mop or mop cloth is not being used Y it is swung out of the way by being thrown laterally sideways from under the groove and then bunched up on top ofthe rollers.

It willnow beseen that the lower part of the mop frame is provided with a cross-bar 26 having a dove-tailed groove. IntoY the groove so formed I insert a cross-bar 21 correspondinglyy formed to t the dove-tail, such bar being provided with a brush 28.

`The brush 28 is provided for the purpose of 55 into the Working parts such as the springs which` are protected by plates which extend over ,operi-' ings at the insides of the frame.

It will also be noted that the cross-bar 21 is held in position from moving laterally by means p of the spring 29 indicated clearly in Fig. 2. The

mop cloth is also prevented from slipping by the projections and recesses in the rollers hereinbefore referred to.

Another advantage I possess in the use of my mop is that When the brush is being used the handle and arm 20 may be swung back into position between the'clips 22. Y

Another advantage of my mop is that the parts are very easy to'assernble and everything remains in place Without the use of bolts, nuts or screws.

'There is nothing to fall off and become lost and no adjustment is necessary. As the mop may be used without using the hands for wringing purposes it will be seen that boiling Water may be employed and the work done in a fraction of the time. There is no'necessity for a woman getting down on her knees, nor is it necessary for her to do any wringing which is one of the serious Yobjections to the use of mops at present in use.

Although I have described with great particularity the construction of my mop it will be understood that various changes may be made without departing Vfrom the spirit of my invention.

What I claim as my invention is:

The combination with a U-shaped rectangular frame having a pressure bar closing the open lowerend. ofl the frame, and a handle socket at the upper end and the side ends each having an open-ended recessand a closure therefor, of upper and lower rollers, the upper roller having spindles journalled'in blocks in the recesses, springs eX- tending. between said blocks and end closures, and

thelower roller havingI end spindles journalledin' the side ends andrprovided withV a handle, and an endless mop designed to extend between the roll ers and normally guided by the pressure bar.
