Be it lmown that I, ARTHUR R. DOUGLASS, a citizeri' of the United :States of America, and a resident of Chariton, county of Lucas, State of Iowa, have invented certain new and useful Improvements in Mop-Wringe'rs, of which the following is afull and clear specification, reference being. had to the accompanying'drawings, in which.

Figure l-is a side elevation; Fig. 2 a rear elevation; and Fig." 3' a plan view of a mop embodying myinvention. Fig. 4:. is a perspective view of a former upon which the coils of the wringing device may be wound to give to the wringer device the desired shape. 7

The object of this invention is'to so construct the device that it will serve to quickly and effectively squeeze water out of mop cloths, the construction of the device being such that it may preferably be madeof a single piece of stout wire suitably twisted and coiled, as more fully hereinafter set forth.

The standard (1 consists of two strands of stout wire twisted closely together to form a substantially rigid upright member, the two strands at the bottom being separated and formed into a'fiat loop 6 adapted to rest upon the floor and serve as a foot or base piece. The upper end of the twisted standard is bent downwardly to form a loop 0 which is adapted to engage over the edge of a bucket, the part cl which depends into the bucket being in turn curved upwardly at its lower end, this upwardly-turned end being connected to the wringing device proper. This wringing device consistsof two wires 6 which are formed of integral 'continuations of the two wires of the twisted part cl.

The two wires e are formed in two spirals which rise from their point of connection to the part d, the coils gradually increasing in diameter toward the top, thus forming a re-' ceptacle for the mop cloths which is approximately conical. The upper extremities of the wires 6 are each connected to the top coil of the other wire, at f, by simply wrapping the extremity of the wire around the top coil, said top coils being flattened, whereby the top of the wringer will be horizontal and will consist virtually of a single horizontal coil, the fastening of the ends of the coils at 7 giving to the top the, necessary rigidity.

this fiQOnadJfiGent tothe bucket, ,thevstandard sufiiciently. hi h to enabletthegoose neckmember (Z to spend into the bucket,

- as shown in Fig. 1." The footi'ofthe-juser is placed upon the base member Z) to hold the device steady, and thenthe mop cloths are 7 lowered into the uppe'ropen mouth of the eonlcal wringer. Then by turning the handle and pressing down on the'mop' lightly,

the coils 6 will act in the nature of a screw thread and cause. themop clothsto work gradually down until they wedge between the lower coils of the wires 6, thereby squeezing the water out; of the cloths with a firm but yielding pressure. After this wringing operation, the mop may be readily "removed from the wringer by simply turning the handle in the opposite direction. To increase the squeezing action on the cloths, I flatten I the coils of the wires 6 at opposite sides, as

shown in Fig. 3, and to still further increase 7 the squeezing action of the coils I preferably shape them on a former or core 9 having a concave surface, such as shown in ,Fig. 4. By thus flattening the. coils at opposite sides, it will be seenthat as the mop is turned these flattened portions will exert an especially heavy pressure upon the mop cloth, while the parts of the cloth engagedby the su'fliciently heavy squeezing pressure to prevent the inop from being freely turned by the operator. Thus flattening the coils at opposite sides is further advantageousfor other. parts of the coils will not be given a the reason that while it gives ample room for'the insertion of the mop cloths into the wringer, it at the same time materially avoids obstructing the entrance to-the pail, this being clearly apparent from an inspectionof Fig.3, in which the dotted circles indicate the rim of the pail, thus not only providing a wringer device of ample capacity. but also giving ample room for dipping the mop into the pail. i

7 It will be observed further that'I provide an approximately comically shaped receiver for the cloths, which receiver is flattened on I opposite sides to give the coils an approximately oval shape in plan, the major axis of the coil ovals being at approximately right i.

anglesto the vertical plane of the support- 1 ing standard, whereby the conical receptacle will be disposed near the edgeof the'pail and thus leave the greater part of the mouth of the pail free for insertion of the mop into the pail. 7 Having thus described my invention, what I claim is:

1. A mop wringer consisting of a single strand of wire formed into a base loop, a

twisted standard whose upper end is bent downwardly so as to depend into the bucket, the lower end of this downwardly-bent part being in turn bent upwardly and the wires of this upwardly-bent part being extended upwardly and formed into spirals whose coils widen upwardly, the upper extremities of each of said wiresbeing connected to the top coil of the other wire.

2. A mop wringer consisting of a means for supporting the wringing device in the pail, and the wringing device consisting of two upstanding spiral wires Whose coils widen upwardly and are flattened at opposite sides to give the coils an approximately oval shape in plan.

In testimony whereof I hereunto afiiX my signature.

ARTHUR R. DOUGLASS.
