My invention relates to a typeof wringerafor mops known. in'the trade as cone type in that an inverted cone with a-largenumber of openings is'suitablysupported and in this cone a wet mop may be inserted, then. by atwist on the handle the map undergoesa twistin the cone, wringing the water from the mop. I'nithis. typesof mop wringer, certain of these are designed to attach to the side of a pail or'built' in theside of aspecial receptacle. One of the. disadvantages ofthis type resides in when a pressure is placed on the mop to wring the same frequently the pail or the receptacle is upset. thereby spilling the dirty water. This is mainly dueto the pressure not being evenlydistributed over the bottom of the attached to the cone wringer andlengaging the paily'or other receptacle in such a position that the downward thrust is in part transmitted to the bottom portion of the pail or receptacle. and

he construction causes this pressure-to be. in such a position that there is practically no danger of upsetting the pail or receptacle'when wringing a mop and exerting athrust through'the'mop handle in twisting the wet portion of the mop in the wringer. A further detail feature of my invention is making the stand or leg construction adjustable as to the cone type wringer so that the bottom orshoe po'rtion'willengage the bottom of the pail and be suitable for different sizes of nails, the shoe preferably engaging the pail adjacent the bottom and sideopposite' the hooks engaging over'the rim. In another form of my 1 invention the leg and shoe construction is rigidly secured to the cone type of wringer and made of the proper length fora certain size of pail.

' This however may be accommodated in pails of uite a number of different-depths and sizes", as the hooks readily permit the change'of in- I clination of the mop'and the position in which the shoe engages the bottom of the pail.

Considered in more detail, other features of coils or convolutions are then secured by longitudinal straps formed of wire welded to the various coils. A pair of these straps are provided with hooks to engage the edge of a pail. Inthe adjustable form the legs have. wirerods adjustable in a clamp having a bolt, the, clamp being secured to the cone wringer onone side, such being thev side having the hooks. In another type withthe non-adjustable leg structure, the straps having the hooks may continue downwardly preferably diverging from the lower pore tion of the cone andv having a connected. shoe structure. to engage the bottom of the pail.

Another feature of my invention involves providing the hook with a pivotal attachment to the cone and such may be done by linking the two arms of the hook to the upper turn or convolution of the wire forming the cone. This takes the: place of a rigid hook and adapts the cone to conform to. the shape and arrangement of hanging of a number of diiferentsizes and shapes of pails.

In a modified construction I provide a telescopic leg assembly with a guide channel structure secured to'the wire cone and have the legs slidably mounted in such guide with a pin and-- perforation connection. This affords a quick adjustment to pails of diifereritdepth without using any hand tools. or the like.

Referringfirst to the construction of the cone wringer, such being designated by the numeral I I, this is preferably formed of a combined helical and spiral winding of stifi wire designated by the numeral i2, this having the base l3 uppermost and converging to the apex I4 at the bottom. This winding commences with an upper coil or convolution l5 and a series of successively smaller turns or convolutions l6 ending in a terminal twist l 'i at the bottom or apex.

These coils or convolutions are secured together by longitudinal straps 20 of which in Fig. 1 there are preferably two of these on diametrically opposite sides secured to each convolution crossed by the strap by spot welding, brazing or the like. There are also hook straps 2| which slightly converge towards the bottom, these being likewise secured to the convolutions by welding or brazing and each has a hook 22 at the top, the hook terminating in a head 23 to make a neat finish and lessen the chances of the cords of the mop catching on the end of the hooks.

These hooks as shown in Fig. 5 engage over the rim 25 of a pail 26, the bottom of the pail being indicated at El.

In the construction as shown in Figs. 1 and 2 I provide a clamp assembly 30 secured to the wire wound cone, this clamp being fitted between the straps 2! having the hooks. The clamp includes an inside plate 3! fitting inside the winding of the cone and a clamping plate 32 on the inside, these being secured together by a bolt and nut 33. If desired this may be adjustable up and down on one side of the cone or the inside plate 3! may be welded or soldered in a fixed position.

The leg assembly of Figs. 1 and 2 indicated as 35 comprise a pair of leg rods 36, this being shown parallel and fitting underneath the clamping plate and contacting directly a series of convolutions of the wire winding. The upper ends 3'! preferably terminate below the base of the cone and below the hooks so that they do not interfere with the attachment to the pail. These legs have a shoe construction 38 at the bottom indicated as having diverging arms 39, a reverse bend 40 and a transverse bottom strip 4| which engages the bottom of the pail and at the ends may contact the side 26 of the pail approximately opposite the portion of the pail engaged by the hooks.

In the construction shown in Figs. 3 and the hook straps 45 are preferably parallel and spaced the desired distance apart. These are secured to the convolutions of the cone winding by welding. brazing or the like and are provided with hooks 46 at the top. The leg structure 4'! is formed integral and has leg rods 48 diverging from the lower ends of the strap portions 45, and is provided with a shoe 419 at the bottom, this being formed by angle bends 50, upwardly ex tending portions 5| meeting at an obtuse angle 52. This construction is intended so that it is to fit pails of approximately the same depth and when the hook engages the rim on one side, the reverse bend portions 50 are intended to engage the bottom and the side wall 26. However this type of construction is quite suitable for a considerable range of pails as to depth and diameter.

In Figs. 6 and 7 I illustrate the hook as having a pivotal connection to the cone type of wringer. In this instance the hook is designated by the assembly numeral 60. This has a pair of spaced arms 6 l, each bent to form an individual hook 62 with a transverse bar 63 engaging the ends of the individual hooks. Each of the bars 6! is formed with an eye 64 loosely wrapped around the upper turn or convolution of the cone forming the wringer proper. This construction may be used with the arrangement having the adjustable leg of Figs. 1 and 2 or the non-adjustable leg of Figs. 3 and 4, the rigid hook manifestly being omitted. This construction permits the cone wringer to be suspended over the upper edge of a greater size range of pails and to be suspended in such a manner that the wringer is given proper support by the leg structure from the bottom of the pail.

As a characteristic of my invention it will be noted that when the mop wringer is attached to the rim of an ordinary size pail with the shoe at the bottom of the leg engaging the pail at substantially its opposite side, the axis of the cone has an inclination, this usually being towards the center of the pail. When a person is wringing a mop they usually insert the Wet mop centrally in the cone and with the handle at approximately the axis of the cone. Therefore the downward pressure is substantially towards the center of the pail, the thrust by the hooks and the leg thrust through the hooks and the leg, thus on opposite sides of. the center, this forming the center of thrust at substantially the center of the pail and hence reducing the danger of upsetting the pail.

In Figs. 8, 9 and 10 I illustrate a modified construction by which there is a slip connection of the leg assembly and a guide channel structure for readily adjusting the leg for the depth of different pails and this without the use of any hand tools such as a wrench or the like. In this construction the cone wringer T5 is formed of a combination helical and spiral winding of wire, the apex end 76 being at the bottom and the base 77 at the top. The upper convolution is indicated as terminating at 78. In the front I attach upwardly extending guide straps 79, there being a pair of these in which the lower ends 86 are quite close together and attached to one of the lower convolutions. These straps extend above the uppermost convolution and have a cross strap 8!. This is slightly arched downwardly from the ends 82. Thus the cross straps and the side straps are formed of one piece. At the back or rear of the cone wringer I also use a pair of rear straps 83 and 34. These straps as well as the front straps are secured to the coiled wire by spot welding or soldering or the like. The straps are placed on the wires to intersect each convolution at substantially right angles. The strap 84 is indicated as attached at its top B5 to the upper convolution adjacent its ends 78.

The guide channel assembly 9! has a longitudinal web SLopposite marginal flanges l2 and inwardly turned rims 93. The flanges are parallel and the web is attached to the various convolutions which it intersects at substantially right angles by soldering, or welding material indicated at 94. 1e f anges have a series of perforations 95. It will be seen therefore that the channels are open at the bottom and top, there being also an open space between the inner edges of the rims 93.

The leg assembly Mil includes a pair of parallel rods If, each of which has an outwardly turned pin 102 at the top. The rods are parallel for a considerable part of their length and then each has a diverging leg section Hi3, both legs at the bottom being joined by a transverse shoe 184. This shoe may be a straight section of wire having the corner bands IE5 or may have a belt as shown in Fig. 4. If desired the leg and the shoe section may be made as shown in Fig. 2. The

pins fit in any pair of the perforations 95 in the flanges, these being opposite, the leg assembly is made of resilient wire having a natural tension to urge the pins outwardly. Therefore as the rods llll may be readily. squeezed together to disengage the pins from any pair of perforations, the rod may be slid up and down in the channel guide, the pins thus give a thrust reaction to the channel guide and thus give a support for the cone .wringer in the bottom of the pail, the shoe assembly engaging the pail preferably on the side the construction without departing from the spirit or scope of the invention as defined by the appended claims.
