PATENT OFFICE 7 MOP WRINGING APPARATUS Edward Pavek, Minneapolis, Minn.

Application February 23, 1933, Serial No. 657,956

' 20 Claims. (01. 15-261) This invention relates to a mop wringing apparatus, and while the apparatus is capable of being secured to a pail and mounted on the pail in various manners, it particularly is illustrated as adevice having means supporting it upon the edge of the pail and being'readily removable from the pail.

It is an object of this invention to provide a .mop wringing apparatus comprising plates relatively swingable toward and from each other to squeeze a mop therebetween, means for swinging one of said plates and means simultaneously engaging the other plate to move it with increasing leverage as said plates approach each other.

It is a further object of the invention to provide a mop wringing apparatus comprising a pair of plates relatively swingable about a pivot toward and from each other to squeeze a mop :therebetween, means for swinging one of said plates, means simultaneously engaging the other plate to move it toward said first mentioned plate, said last mentioned means being movable toward :the axis of said pivot as said plates approach each other. i g F It is a further object of the invention to provide a mop wringing apparatus comprising a frame, a plate pivoted in said frame, a second plate connected to said first mentioned plate, a

roller carried by said second plate and a cam engaged by said roller as said first mentioned plate is swung to move said second plate toward said first mentioned plate, together with a guide means for said roller.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accom-v p-anying drawings, in which like reference characters refer to similar parts throughout the several views and in which:

Fig. 1 is a view in vertical section of the apparatus supported by a pail, taken on line ll of Fig. 2,. as indicated by the arrows;

Fig. 2 is a view in end elevation of the device, the supporting pail being shown in vertical section;

Fig. 3 is a top plan view of the device; 7 Fig. 4 is a partial view of the upper portion of Fig. 1, shown on an enlarged scale;

Fig. 5 is a substantially horizontal section taken on line 5-5 of Fig. 4, as indicated'by the arrows Fig. 6 is a view similar to Fig. 1, showing the parts in mop-squeezing position;

of Fig. 1;

-- Member '3! has an upper portion 3l'a extending Fig. 8 is a view in side elevation of a modified form of the mop stick engaging means;

Fig. 9 is a top plan view of Fig. 8; and

Fig. 10 is a view in side elevation of Fig. 8, as seen from the left thereof, Figs. 8, 9 and 10 be- 5 ing shown on an enlarged scale.

Referring to the drawings, particularly Figs. 1 to '7, a pail 20 is shown adapted to contain wash Water such as usually used in mopping floors. A frame member 25 is shown, and while this frame 10 member might be secured to or supported in the pail in various ways, in the embodiment of the invention illustrated it is shown as having a'pair of side plates 2 la, each of which has a slot portion Zlb at one side forming a tongue or hook 2lc adapted to extend over the edge of the side or partition 26a of the pail 20. The said side or partition extends into the slot 2H) and the side portions Zia have their edges extending downwardly along the side or partition a and said 20 side portions extend substantially at right angles to said side or partition. The side plates 2 la are connected by headed rivets 22 having their heads at the outer sides of the side plates, which rivets have thereon and extend through sleeves or tubular members 24 engaging the adjacent sides of said side plates. A pivot member 25 extends through side plates 2 la, having washers 26 at the outer sides of said plates held in place by pins or split key members 21 extending through pivot 25 30 at the outer side of the washers 26. It may be stated that side plates 2 la are connected at their lower ends by a portion 2ld extending therebetween adjacent the bottom of pail 2B. The pivot 25 extends through arcuate slots 28a formed in the parallel side portions 28?) of a plate 28. Plate 28 as clearly shown in Figs. 1 and 3 extends substantially the distance between the side plates 2 la and plates 28b extend in parallel relation and parallel to the side plates Zia. The side portions 282) have a plurality of holes 2811 therethrough. Plate 28 is slightly curved at its bottom and formed with hinged lugs through which extends a hinged pintle 29 also extending through hinged lugs at the bottom of the plate 30 interfitting with the lugs on plate 28 so that

plates

28 and 30 are hinged together at their bottom portions. Plate 30 extends between the side portions 28b, and above the same, said plate having a portion. 30a bent outwardly and downwardly at its upper end." Portion 30a has a slot 391) formed therein through which extends a member or bar 3! connected at its lower portion to the rear of plate 30 by some suitable fastening means such as the rivets 32.

forwardly of plate substantially at right angles, and side portion 3Ia is bent into U shape so as to have parallel side portions. Said parallel side portions are each provided with a slot 311) and a stud 33 extends through said slots, being threaded at each end to receive nuts 34 which engage the washers 35 disposed at the outer sides of portion 3 la and extending across the slots 31b. Stud 33 has a sleeve 36 thereon extending between the sides of portion 3 la and on which is'journaled a roller 31 having a concave groove in' its periphery. It will be seen that the stud 33 can be disposed in different portions in the slots 3lb, the same being movable when nuts 34 are loosened and being capable of being tightened inthe desired position by said nuts. The plate 28 at its outer side or the side remote from plate 30 has a pair of bearing sleeves 38 secured thereto in any suitable manner, as by welding, and a rod 39 extends through and between said sleeves, being 'journaled therein and having at its ends rollers 40 secured thereto. The rollers 40 rest upon and are adapted to travel along a cam surface 280' formed on the top of each side plate'2 Ila as shown in Fig. 1. Curved guide rods 4| are secured in the plates Zla at the outer end of the cam track 7 28d and extend in curved formation some distance over said cam tracks.

In operation, when a mop is to be squeezed;

the same will be disposed between the

plates

28 and 30 as they are in the position shown in Fig. 1. The operator then disposes the mop stick 42 in the position shown in dotted lines in Fig. '1', the same being disposed between the sides of portion 3la and in'contactwith the roller 31. The operator can now swing the handle to the left as shown in Fig. 1 and this causes'plate 30 to swing about the axis of pintle 29 and move toward plate 28. As plate 38 is thus swung, the lower end thereof moves to the right and due to the resistance of plate 28 and the presence of the mop between said plates, pivot 25 moves to the left in slot 28a.

' The plates finally reach approximately'the position shown in Fig. 6. It will be s'eenthat the lower end of the plate 28 will be moved tothe right in I the lower end of plate 36 and the rollers 40vril1 be drawn along the cam track 280'.

rollers 40 thusapproaches the axis of the pivot 25 and an increasing leverage is had moving the Y plates together as bar 3| and mop handle 42'are swung to the left. The mop will thus be thoroughly squeezed and the water therefrom will run out between the bottoms of the side plates and through the holes 28d into pail 20. The operator can now swing the mop stick 42 tothe right and thus move it parallel to plate 30 until it is out of "without the necessity of the operator bending over the pail 20. It is more difficult to bend down over the pail and operate a lever or handle to squeeze the mop than it is to perform the operation above described and with the described operation the operator does not have to b'ring'his face down over the pail 20 which usually-com tains hot water.

In Figs. 8 to 10 a bar 45 is shown, which will" be used in place of the bar 3i. The bar 45 has The axis of a rivet 46 secured therein passing through an aperture in a hook member 41 having one portion extending parallel to one side of the bar 45 and having a protuberance 47a thereon engaging the side of the bar 45. A spring 43 surrounds rivet 46, bearing at one end against member 41 and at its other end against a washer 49 held in place by a screw 56 threaded into the rivet 46 and having a slotted head. Spring 48 is of coiled formation with a larger diameter adjacent member 41 than adjacent the washer 49. Member 41 extends around the bar 46 and has a substantially semi-cylindrical hook portion 471) at its outer end.

In operation, when the mop is placed between plates and 30, the operator will swing the mop handle 42 into the hook portion 41b of the plate 41 and bar 45 will be swung to the left as already described for bar 4!. It will be noted that bar 41 can swing about the axis of rivet 46 as'indicated by the dotted lines in .Fig. 8 and can "also swing toward and away from the plate 45' as indicated by the dotted lines in Fig. 9.

The mop stick 42 can thus be moved in a somewhat irregular path and plate 4'! will aocommodate-itself to such movement.

From the above description it is seen that applicant has provided a simple and yet very efficient structure of mop squeezing apparatus. The apparatus is adapted to be removably supported in a pail as shown, or it may be permanently secured in a pail. The parts are comparatively few in number and can be strongly and ruggedly made. It is' obvious that the device will have a high degree of utility for the purpose intended. j It will, of course, be understood that various changes may be made in the form, details, ar-

- rangement and proportions of-theparts, 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 theparts and. combinations of parts disclosedand defined in the appended claims.
