24 Claims.

This invention relates to a mop wringing device, and while the invention may have various applications, it particularly is designed as a mop wringing device adapted to be carried by a pail in which the wash water or rinsing water for the mop is carried. While various mop wringing devices have been proposed, it has heretofore usually been necessary for the operator to operate either a manual or pedal lever for squeezing the mop.

"'- In the particular type of mop wringer or squeezer illustrated, it has usually been the practice to provide a lever located quite close to the pail for moving the mop squeezing elements together. This necessitated the operator stooping over and usually getting his face more or less directly over the hot water in the pail. Such an operation is tiring and unpleasant.

It is an object of this invention, therefore, to provide a mop wringing or squeezing device cornprising members movable towards each other, to-I gether with means adapted to be engaged by the handle of the mop so that it is merely necessary to swing the handle oi the mop with the mop between said members, to squeeze the mop. The

handle can be easily swung without the operatorv having to bend over very far.

It is a further object -of the invention to pro vide a mop wringing or squeezing device adapted to be used with a pail and comprisirrf a iraine, a pair oi swinging plates movable toward and from each other carried on said traine, one ol' said plates having an upwardly extending portion with means adapted to be engaged by the mop handle whereby a handle equipped mop can be placed between said plates, the handle engaged with said means, and said handle and plates moved to squeeze the mop.

It is still another object of the invention to provide a mop wringing or mop squeezing device comprising a frame adapted to be supported by a pail, a pair oi revolubly movable members or plates mounted in said rame,.a roller engaging one of said plates for moving the saine, said roller preferably being adjustable to vary the movement of said plate, together with means for moving the other plate to cause approaching movement of said plates.

Itis still another object of the invention to provide a mop wringing device comprising a swinging plate and a device of novel form carried by said plate adapted to be engaged by the mop handle to be moved thereby to swing said plate.

These and other objects and advantages of the invention will be fully set forth in the following the accompanying drawings, in which like reference chai"-y acters refer to similar parts throughout the several views, and in whichz'- Fig. l is a view in side elevation of a mop wringing device embodying the invention, a pail being shown partly in section;

Fig. 9 is a partial view similar to Fig. 6, showing a further n'odication.

Referring to the drawings, a pail 10A is shown of substantially cylindrical form having a slight are towards its upper end and equipped with a bead at its upper end. A mop' wringing device is shown comprising a frame designated generally as ll, said frame comprising parallel side members lla connected at their bottoms by a portion 1lb thus forming a substantially U-shaped frame. Members 11a have plates 12 riveted thereto and extending parallel thereto, said plates having downwardly extending portions 12a forming in eiiect hooks adapted to extend over the top edge of the pail 10 at spaced points to support the frame 1l. The side members 11d are apertured at their upper ends to receive a rod 13 extending therebetween, the' same having a cotter pin 14 extending therethrough at one end at the outer side or" one of said side plates and having its end bent downwardly and then inwardly substantially at right angles at its other end forming the portion 13a. Portion 13ais adapted to engage with the edge of a plate 15 secured to one of the plates l2. A bolt 16 eX- tends through plates l2 and 15 and through a slot 15a in the plate l5 and is threaded at its outer end to be engaged by a thumb nut 1'7. Plate `15 can thus be moved upwardly and downwardly and held in different positions by tightening the thumb nut 17. The member 13a will thus be held in diierent positions according to the position of plate l5. A member designated generally 2 as 1B is traversed by the pivot rod 13 and swingable about the axis of said rod. Said member 18 comprises a rear plate 18a and side plates 18h extending forwardly therefrom substantially at right angles. The side plates 18h are substantially of sector-shape, having curved upper ends which are bent slightly outwardly. A pair of angle bars 19 are secured to the rear of plate 18a, which plate extends upwardly in substantially triangular form, said angle bars being secured in any suitable manner as by the rivets shown. Bars 19 extend above plate 13a in slightly spaced relation and a flat bar 20 is secured between bars 19 and extends thereabove, the same having secured thereto a plate 2l which has a narrow strip at one end, one portion of which iits alongside of bar 20 and is apertured to have pass therethrough a screw 22 secured in the bar 20 and have a head countersunk in said bar. Screw 22 is equipped with a nut 23 and a compression coil spring 24; surrounds said screw and is disposed between said nut and plate 21. Plate 21 has an end portion 21a extending outwardly and curved A laterally from bar 20 and said plate has a much wider portion 2lb curved into substantially semicylindrical shape to form a hook. Portion 2lb has its concave portion covered with a soft leather member 25, the edges of which are folded over the edges of portion 2lb and held in place at the outer side of said portion by the lacing 26. The

free edge of the semi-cylindrical portion of member 21 extends in an inclined direction so that the opening at the side thereof is wider at the lower end than at the upper end. The plates 18h have a reinforcing strip 18o extending across the front thereof at their upper inner portions, the ends of said strip extending across the plates 18h at their outer sides and being riveted thereto. A plate 27 is provided, adapted to extend between the plates 18h, said plate being slightly curved in a compound curve as shown in Figs. 1 and 3. Said plate is bent at an angle adjacent one end and has an eyelet formed at its lower end traversed by a pivot pin 23 which extends through and between plates 18h, being held therein by being headed at one end and having a cotter pin 28a extending therethrough at its other end. A torsion spring 29 is disposed at each end of the pivot pin 28 surrounding the same and having one end bearing against plate 27 and its other end bearing against plate 18a in the corner between the latter and side plates 18h. These springs tend to keep plate 27 moved away from plate 13a, and moved against strip 18o. Bars 30 l' are pivoted by the headed rivets 31 at their lower ends to the side members 11a, said bars extending upwardly and having extending therebetween and secured therein the headed pin 31 having collars 32 thereon between the ends thereof and between the same and bars 30 are disposed rollers 33. These rollers engage the outer side of plate 27 and act in the operation of the device to move said plate toward plate 18a. Bars 30 are bent slightly intermediate their ends and just below said bends they are disposed alongside of the plates 12b secured to and extending inwardly from said members 11a, said plates being shown as forming part of the plates 12. The plates or portions 12b have a plurality of holes 12o therethrough and headed and nutted bolts 34 pass through one of these holes and the bars 30 so that said bars and hence the rollers 33 can be held in different positions. A drain pan 35 is secured to side members 11a, the same having a narrow ilange extending about its sides and rear end and having a bottom inclining downwardly into the pail 10. Plate 27 is provided with a plurality of holes 27a and said plates 18D are provided with a plurality of holes 18d, these holes being provided for the Vpassage of the water when the mop is squeezed.

In operation the device will normally occupy the position shown in Figs. 1 and 2. The wash water will be placed in the pail 10 and when it is desired to rinse and squeeze the mop, the wet mop will be placed in the pocket formed by

plates

18a, 18h and 27, which pocket, as clearly shown in the drawings is the shape of a sector of a cylinder. The mop is placed in said pocket and the operator then moves the handle 36, shown in dotted lines in Figs. 1, 2 and 3 into the portion 2lb of plate 2l, the same moving between the end of said portion and the portion 21a. The handle is then engaged in the semi-cylindrical portion 2lb and swung forwardly transversely of the pail l0. The opening in member 21 being wider at the bottom facilitates the entry and exit of the mop stick. When the handle exerts pressure on portion 21h it pivots on the bolt 22 and swings into the position shown in dotted lines in Fig. e, so that it is directly in front of bar 20. The operator now merely swings the mop handle forwardly and plate 18a is moved to the left as seen in Figs. l and 3, plates 18h moving at the side of plate 27. Plate 27 is engaged by the rollers 33 and as plate 18a swings toward the left, the rollers move upwardly on plate 27 and it is moved toward plate 18a. The mop is thus squeezed between plate 27 and plate 18a. The water squeezed from the rnop passes through the holes 18d and 27a and also runs down between plates 13ar and 27 into the drain pan 35 from which it runs down into the pail l0. It will thus be seen that the operator can squeeze the mop without bending down low over the bucket of hot water. All that necessary is -merely to hold the mop handle at a point high above the bucket and swing the handle forwardly over the bucket. When the handle is swung back, the springs 29 again move plate 27 to its normal position and the mop can be lifted from between

plates

18a and 27. The rollers 33 can be located in different positions by placing the bolts 34 in different holes 12e. This causes a diierence in the distance the

plates

18a and 27 are spaced and also varies the leverage exerted on plate 27 in squeezing the mop. By moving the plate 15, the portion 13a of the pivot 13 is stopped in a different position and this results in the member 19 being held in a more nearly vertical position. rihis adjustment is provided so that member 19 will not extend at too great an angle to the vertical so as to accommodate buckets with dii'lerent degrees of flare and to suit various operators.

In Figs. 6, 7 and 3 a niodiiled form of con-- struction is shown. ln this form a frame Li() is provided having side members 40a extending downwardly into the bucket and connected by a lower bar 40h. Portions 40a and 40h are shown as bent from a single bar and riveted at the upper ends of bars loa to the upper part of frame 40.

rame 40 also comprises side plates 40o of general sector shape, the same having rearwardly extending projections 39 forming hooks adapted to extend over the rim of the pail 10. A pivot 1":

member Lil extends through and bet' een plates 49o, the same being headed at one end and held in place at its other end by the cotter pin 42. A member e3, comprising a plate 43a, is provided, the same also comprising a pair of angle bars 43h securedto the back of the plate 43a. Pivot 41 extends through the bars 43D so that member 43 is pivoted to the plates 40e and swingable about the axis of pivot 41. The angle bars 43h extend beyond the upper end of plate 43a, which plate is of the general shape of plate 18a already described, said bars being in spaced relation above said plate. The bar 20 already described having member 2l carried thereby, is secured between the upper ends of bars 4317 as described in connection with Figs. 1 to 3. A pivot 44 extends through the bars 43h below the pivot 4l and a plate 45 is provided of a width to move between plates 4Go, the same being slightly curved in a compound curve and having its lower end bent at an angle and provided with an eyelet through which pivot member 44 passes. Pin 44 is headed at its ends to be retained inthe bar 43h. The plates 40o as shown have curved tops, the edges of which are bent slightly outwardly, and said plates have formed therein a plurality of apertures 40d shown as rectangular slots arranged in two rows. Bars 46 are provided extending along the outer sides of plates 40e and having inturned ends 46a adapted to be received in one of the slots 40d. Bars 46 are bent transversely and then inwardly substantially ninety degrees, the inwardly extending portions 46h having secured therein a headed pin 47 having spaced collars 48 thereon. Rollers 49 are journaled on pin 47 between collars 48 and the members 46D respectively, and said rollers are disposed to engage the outer side of the plate 45. Plates 40o have holes 40e therein at the inner ends of the rows of slots 40d and bolts 50 extend through holes 40e and through holes in the bars 46, said bolts having heads countersunk in the plates 40e and being equipped with nuts at the outer sides of bars 46. Frame 40 has a drain pan 5l secured thereto beneath

plates

43a and 45, the same having a narrow ange about its sides and rear end and having a bottom sloping downwardly into the pail 10. Torsion springs 52 extend about the ends of pin 44 and have one end engaging plate 43d and another end engaging plate 45, said springs acting to move plate 45 away from plate 43a. The plates 40e are provided with drain holes 40j and plate 45 is provided with drain openings 45a.

In operation, when it is desired to squeeze the mop, the same is placed between the

plates

45 and 43a and between the side plates 46c. These plates define a recess shaped substantially in the form of the sector of a cylinder. The operator then moves the handle into the hook portion of plate 21 and swings the handle forwardly transversely of the pail 10. The handle moves plate 2l and member 43 forwardly as indicated in Fig. 7 and as said member moves forwardly, plate 45 is moved against the rollers 33, said rollers moving upwardly along plate 45 so that said plate is also moved toward the plate 43. The mop is squeezed between the

plates

43a and 45, the water from the mop draining through holes 40j and 45a and running down between

plates

45 and 43a into the pan 51 from which it drains into pail 10. The bars 56 can be moved to have their portions 46a extend into different slots 40d and the position of the rollers 49 is thus changed. The rollers can be moved either inwardly to cause a closer approach of

plates

43a and 45, or the rollers can be moved upwardly, giving more leverage in the movement of the plate 45. When the mop handle and member 43 are moved upwardly and rearwardly from over the pail l0, springs 52 move plate 45 to normal position and the mop can be lifted from between

plates

45 and 43a.

In Fig. 9 the structure is the same as shown and described in connection with Figs. 6, 7 and 8, except that in place of having the slots 40d and the bars 46, holes 40g are provided. Several pairs of said holes are shown disposed at different distances vertically of said plates 40o and also disposed different distances from the edge of said plate. A pivot bolt 54 is adapted to pass through holes 40e and to carry rollers 55 engaging plate 45. Pivot bolt 54 will have a head at one end and be held at its other end by a Cotter pin. By disposing the pivot bolt 54 in the different holes,the position of the rollers 55 engaging plate 45 can be changed.

From the above description it is seen that applicant has provided a mop wringer which is simple in construction and which is very easily and conveniently operated. It is not necessary for the operator to bend low over a bucket of hot or steaming water and the inconvenience of bending down over the bucket and also the unpleasant contact with the steam from the water, are avoided. The handle of the mop is easily and quickly engaged with the member 21 and as above described, it is only necessary to swing the handle of the mop forwardly over the pail to eifect the squeezing or wringing operation. The mop handle being moved towards and over the pail there is no tendency to upset the pail. The mop is eifectively squeezed or freed of water and the water drains quickly back into the pail. The device is easily and quickly placed in operative position on the pail. The parts are few and the structure is quite rugged. Suflicient exibility is provided to give the desired operating conditions and to suit the mop being used. The device has been amply demonstrated in actual practice and found to be very successful and efficient.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims` What is claimed is:-
