7 WRINGER Application filed March'IB, 1931. Serial No. 523,739.

My invention relates to wringer devices used or useful for mopping of floors and the like.

Objects of my invention are:

To provide asimple, convenient, and easily operable wringer deviceformopping;

To provide compartmentstherein for: clean and unclean water orsoapy .or otherwise prepared fluid adapted'to be used in mopping;

To provide thereon abrake means to retain the device in position while a mop is being wrung out or while the device isintended to stand still on an inclined floor;

' To provide thereon a wringer means for each compartment requiring only one movement of a handle to position the wringing rollers for mop wringing over either one of the compartments; 1 v I To provide thereon a mop feeding means which also tends to increase the wringing out of the mop; I

To provide thereon a discharge-control N means having one drain valve connected to all compartments and having one discharge outlet so that the contents of any one orof all of the compartments can selectively be discharged, wholly or in part, while the device remains in one position;

To provide thereon a means whereby the movable roller is automatically held in wringing relation with the companion roller after the samehas been moved into that relation;

To provide thereon an adjusting means to vary the tension of the springs which act on the rollers over the compartments.

Other objects will be pointed out herein below or will become obvious or apparent or N will suggest themselves upon an inspection of the accompanying drawings and this specification. v w

I attain my objects by the mechanism illustrated in the accompanying drawings, in

which: Fig. 1 is a plan view of a wringer device for mopping embodying my invention.

Fig; 2 is a side view of the device of Fig. 1.

Fig. 8 is a transverse section takenon the line 3-3 in Fig. 2.

Fig. 4 is a transverse section of the drivin roller taken on the line H in Fig. 3.

imilar reference characters refer tosimilar parts throughout the views.

The tank, as shown, i divided into two compartments A and B, and has four wheels G on the bottom thereof. All of the wheels may be mounted on castors for easy steering of .the device but it is preferred that only the two wheels on one end be mounted on castors 150 so that one brake will hold the device against lateral and circular movement.

. The castors 10 are mounted on thebottom of the tank at one end thereof and carry the steering wheels and usual brackets and wheels journaled therein, well known in the art, are mounted on. the bottomjofthe tank at the other end thereof.

The valve D, as shown, is a three way valve having the inlet 11 with the pipe connection 12 leading to the compartmentA and also having the inlet 13 with the pipe-connection l l leading to the compartment:B and also having the outlet 15. Upon rotation of the handwheel 16, in respective directions, either the inlet 11 or the'inlet 18, or both, may be connected to or with the outlet15 so that the device may be moved into a suitable position therein the outlet is disposedflover a discharge receptacle and the. contents of either one or of both of the compartments can be discharged with one positioning of the device.

The bracket 17 is mounted on one end of the device and carries the lever 18 pivoted thereon by means of the pivotpin 19. The link 20 is pivoted onto the lever at 21' and extends downwardly. The brake shoe 22, adapted to contact the floor'upon which the device rests, is mounted on the stem 23 which is guided on the bracket 24: and which is pivotally connected to the link at 25. V V I The pivots 19 and 21 are arranged so that the same are beyond dead centers-when the lever contacts the bottom of the slot in the bracket 17 and thereby lock the brake when it is applied. The drawing shows the lever moved far enoughto contact the brake shoe on the floor; an additional downward movement of the lever moves the pivot 21 past the dead center with the pivot 19 and thereby tends to raise the device and puts the weight of one end of the device onto the brake for effective braking thereof and at the same time locks the brake.

The lever 18 is bent to remove the free end thereof from the tank when the brake is applied so that the free end can be taken hold of to release the brake and to extend the free end thereof over the top of the tank when the brake is released so that the lever remains in brake releasing position due to gravity thereof. 7

. The brake shoe may be madeof rubber or wood or other material to be somewhat resilient and having the property of frictional engagements with floors or may be made of metal or other material with a friction producing lining on the bottom thereof.

The rollers E and F are journaled respec: tively in the two bearing blocks 26 and 26a which are slidable in and guided by the frame bars 27 and 28 extending along the top of the tank at each side thereof and are tied together by the frame parts 29 extendingtransversely of the tank at each end thereof.

One end of each of the springs 30 abut the respective bearing blocks and the other ends thereof abut the respective washers 31; The adjusting screws 32 abut the respective ones of'said bearing blocks and are threaded into the spacers 33 located atthe end of the bars 27 and 28. l

The springs provide lateral resiliency for the rollers E and F so that the same can move laterally to some extent when a mop or other implement of various thicknesses is being wrung out and always tend to keep the rollers against the mop.

The spring adjustment provides means whereby the mop wringing pressure can be varied to suit different thicknesses of mops or to wring mops more or less dry.

The roller G is journaled in the two bearing blocks 34 by means of the shaft 35 which carries on one or both ends thereof a crank 36 for rotation of the shaft and the roller thereon.

The bearing blocks 34 can slide longitudinally of the bars 27 and 28 and are guided thereby and between them.

The roller G is movable into mop wringing relation with the rollers E and F or to any position between the same by means of the below described toggle mechanism.

The brackets 37 are secured to the respective bars 27 and each has the pivot pin 88.

The levers 39 have one of the ends thereof pivoted onto the respective pivot pins 38. The round bar 40 connects the other ends of the levers 39 and at the same time serves as a handle to propel the device as well as to steer the same.

The links 41 have one of theends thereof the corrugations 43 to more effectively take hold of the mop as the same feeds through the rollers and at the same time squeezes the mop more effectively as the sides of the corrugations engage the same.

As to operation of the device, starting from the position of the parts or elements as shown and described: j

When the parts or. elements are in the positions shown in full lines in-Figs. 1 and 2, the handle40 is outward of. one end of the device where it'can be taken hold of conveniently for propelling and steering the device. In this position, the links 41 are substantially horizontal, sufiiciently so to prevent the roller G from backing away from the roller E in themanner of toggle mechanisms when a mop is passing through the rollers E and G and thereby provides an effective lock for the roller G against reve'rselateral movement thereof.

Upon holding the end of a mop into the junction of the rollersE and G and a rotative movement of the driving roller G by means of the crank 36, the mop will be fed in between the rollers E and G and is wrung out over the compartment B while it is so being fedv as is well known. The springs 30 allowing; for unequalities and spreading of the roller E.

Upon movement of the handle 40 arcuately upwardly, the toggle mechanism moves the roller G away from the roller E as indicated in dot and dash lines in Fig. 2. Upon continuation of this arcuate movement inwardly of the device, the roller G is brought into wringing relation with the roller F as is also indicated in dot and dash lines in Fig. 2.

A rotative movement of the crank will wring out a mop over the compartment A in the manner just described.

A reverse movement of the handle 40 brings tlfie parts back to the full line positions there- 0 Changes and modifications can be made in the structure and arrangement of the parts or elements shown and described within the spirit and intent of my invention and of the appended claims; therefore, without limiting myselfto the precise structure and arrangement of the parts or elements as shown and described i I claim:
