Claims.

The invention aims to provide a new and improved device for application to a bucket or the like, for the purpose of wringing a floor mop.

In carrying out the above and, a further object is to provide a novel construction which will automatically exert squeezing pressure upon the mop, simply by inserting said mop and pushing downwardly upon its handle.

A still further object is to provide a construction which is rather simple and inexpensive, yet easily operated, efficient and durable.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a perspective View of. the wringing device, showing the bucket with which it is to be used, in dotted lines, said wringing device being 20 shown in position toreceive a mop.

Fig. 2 is a vertical sectional view through the wringing device and the bucket showing the mop inserted in dotted lines and illustrating the mop squeezing parts in operative position.

The construction selected for illustration will be rather specifically described, with the understanding however, that within the scope of the invention as claimed, numerous variations may be made.

A horizontally elongated frame 5 is provided to rest upon a bucket or the like 6, and if desired appropriate means (not shown) may be provided for connecting said frame and bucket. If the usual bucket handle be sufficiently long to swing 5 upwardly over the frame 5 and parts carried thereby, said handle may be used for carrying both the bucket and the entire wringing device. Otherwise said wringing device may be provided with a suitable handle (not shown) which will serve as carrying means for both the wringing device and the bucket if the latter be connected with the frame 5.

The side bars of the frame 5 are denoted at l and the end bars at 3, and over one of these end bars, a suitable guide 9 is preferably provided to guide the mop into the bucket for slushing. The side bars I are provided near one end of the frame with upstanding posts It and are provided near the opposite end of said frame with similar posts til for a purpose to appear.

A U-shaped frame H is provided to extend into the bucket E and to project somewhat above said bucket, the side arms l2 of said frame H being offset outwardly at their upper portions and having said upper portions suitably secured 1937, Serial No. 161,151

at I3 to the intermediate portions of the side bars '3 of the frame ii.

A horizontally elongated carriage bar H!- extends between the lower portions of the arms I2 and is slidably connected with said arms,

preferably by providing it with slots 15 through which these arms pass. The ends of the bar [4 are connected by coiled springs l6 with suitable parts of the frame structure, said springs acting to yieldably hold said bar 54 in a raised position (Fig. 1). In the present disclosure, the upper ends of the springs it are engaged with eyes IT at the juncture of the arms 12 with the side bars I, and said eyes may well constitute portions of eye bolts or the like for securing said arms and side bars together.

Two swingable arms l8 are disposed at one side of. the carriage bar l4 and incline steeply therefrom through one end of the frame 5, and two additional swingable arms w are disposed at the opposite side of said bar Hi and incline steeply therefrom through the other end or through the intermediate portion of said frame 5. Bolts l9 pass loosely through openings in the lower ends of the arms l8 and 18 and pass through other openings in the bar I4, and coiled over-load springs 29 are mounted on said bolts. This construction permits the upper ends of the arms It to swing toward the upper ends of the arms l8 and vice versa, and also permits the lower ends of said arms l8 to yield away from the lower ends of the arms Hi and vice versa, to relieve strain on the parts when wringing a mop, as will be hereinafter more apparent.

Suitably secured to the upper portions of the arms I3, is a wall 2!, and a similar wall 2| is secured to the upper portion of the arms I8 the wall 2| being preferably of greater height than the wall Zi andbeing curved to constitute a back stop 22 which is instrumental in guiding the mop into the space between the two walls 2| and Zi A bottom 23 extends between the lower portions of. the walls 2! and Zi and cooperates therewith in forming a receptacle to receive the mop. While this bottom may be mounted in any suitable way, I have shown it secured to the lower edge of the wall 2! and passing under the wall 2%, said bottom being provided with slots 24 through which the arms l8 pass. Preferably a substantially U-shaped reinforcing frame 25 supports the bottom 23 and is secured at its ends to the arms 58.

Two horizontally elongated carriages 26 are slidably connected at their central portions with the upper end portions of the side arms l2 of frame H. Levers 21 are fulcrumed between their ends at 28 to the carriages 26, at one end of the latter, said levers declining steeply toward the end of the frame 5 which is provided with the posts ID, the lower ends of said levers being connected with the upper ends of said posts by pivoted links 29. The upper ends of the levers 21 are connected suitably with the upper portions of the arms I8, a rock shaft 30 integral with said levers being engaged with suitable arm-carried brackets 3| for this purpose, in the present showmg.

Additional levers 2! decline steeply toward the end of the frame 5 which is provided with the posts W, the intermediate portions of these levers being fulcrumed at 28 to the ends of the carriages 26 remote from the levers 21. The lower ends of these levers 2! are connected with the upper ends of the posts ||l by suitable hangerlinks 29 The upper ends of the levers 2'! are pivotally connected with the upper ends of the arms |8 in any suitable manner. In the present showing, it may be considered that the rod 30 is secured to' the arms l8 and to the wall 2| and that the upper ends of the levers 2! are pivotally connected with the ends of said rod 30 By normally holding the carriage bar 4 in a raised position, the springs I6 similarly hold the arms l8 and l8 the walls 2| and 2| and the bottom 23 in a raised mop-receiving position. When the mop is placed between these walls 2| and Zl and pushed downwardly, said walls 2| and 2l the bottom 23, the arms I8 and l8 and the carriage bar Hi all move downwardly together, during which movement, the

levers

21 and 21 are caused to swing from the position of Fig. 1 to that of Fig. 2, with the result that said levers inwardly swing the arms l8 and I8 and the walls 2| and 2 l to effectively squeeze surplus water from the mop. As soon as. the downward pressure upon the mop handle is relieved, the springs l6 return the carriage l4 and parts connected therewith to raised position, and at the same time, the

levers

21 and 21 and associated parts return to their normal positions, again separating the walls 2| and 2 l and again placing them in readiness to next receive the mop.

It will be seen from the foregoing that novel and advantageous construction has been disclosed for providing an expansible and contractible mopsqueezing receptacle which is movable by a downward push on the mop handle, from a normally raised mop-receiving position to a lowered mopsqueezing position. Obviously this same general result could be obtained with variations over the present disclosure and it is therefore to be understood that this disclosure is illustrative rather than limiting.

When the specific construction herein shown or a similar construction is employed, the

levers

21 and 21 may have a tendency to continue inwardly pushing the upper ends of the walls 2| and 2| after the lower ends of said walls have moved inwardly as far as the compressed mop will permit. When this occurs, the over-load springs l9 permit the lower ends of the arms l8 and l8 to move away from each other, relieving strain upon them and associated parts.

It is preferable to suitably connect the side arms I 2 of the frame H with the side bars I of the frame 5, by suitable braces 32 but if I2 and I should be welded together or secured in some other way which would not require bracing, said braces could of course be dispensed with.

Excellent results may be obtained from the general construction shown and described, but attention is again invited to the possibility of making variations within the scope of the invention as claimed.
