BY 7 I Patented Oct. 18, 1932 UNITED STATES RALPH H. ROBB, OF OAKLAND, CALIFORNIA MOP WRINGER;
Application filed December 23, 1931. Serial No. 582,705.
This invention relates to wringers and especially that type which is employed for.
wringing floor mops, swabs, and like devices.
The object of the present invention is to generally improve and simplify the construction and operation of mop wringers to provide a mop wringer which is adapted to be permanently attached to a bucket or like re ceptacle so as to be in a position where the mop may be expeditiously and quickly wrung to such an extent as to remove the major portion of the water content, thereby leaving the mop when removed from the wringer in a condition to absorb water from the floor or other surface to be washed and dried; to provide a wringer which directs the water back into the bucket during the wringing operation; and further, and more specifically stated, to provide a wringer the shape of which is that of an inverted cone so that water may be expressed from the mop material both by downward pressure on the mop and by wringing action, and also to provide a wringer which permits free liberation and discharge of the Water during the wringing operation and which presents a surface which will securely hold and grip the mop material thereby permitting the mop to be more thoroughly wrung.
The wringer and the bucket to which it is attached is shown by way of illustration in the accompanying drawing, in which Fig. 1 is a plan view of the bucket and the wringer attached thereto.
Fig. 2 is a central vertical section of the bucket and wringer, said view showing the mop inserted in the wringer.
Fig. 3 is a perspective view of the bucket showing the wringer attached thereto.
Fig. 4 is a perspective view of the mop.
Referring to the drawing in detail and particularly Figs. 1 and 3, A indicates a bucket or like container which is substantially triangular shaped in cross section to provide a support for a mop wringer generally indicated at B, and also to provide ample space such as shown at O for the insertion of a mop when rinsing or wetting the same. The bucket is constructed of metal or any other suitable material. It is provided with a bottom section 2, an upper rolled reinforced edge 3, and a handle 4 whereby it may be conveniently carried from place to place.
The wringer forms the subject matter of the present application and isbest illustrated in Figs. 1 to 3. It consists of a top plate 5, the outer edge of which is flanged and rolled in under or interlocked with relation. to the upper rolled edge 3 of the bucket to permanently secure it thereto. The edge indicated at 6 is also flanged to reinforce and impart rigidity to the plate. An opening '7 large enough toreceive a mop such as shown at 8 is formed in the plate and the edge is provided with a down-turned annular flange 9 to which is secured a plurality of spaced wire rods 10. The wire rods are arranged to form a body member ofl'an inverted truncated coneshape and the lower ends of the wire-rods are secured to a cone-shaped bottom member 11, the apex of which projects upwardly intoethe body and centrally there-' of. The cone-shaped bottom member 11 is provided with a series of slots as shown at 12 and these slots, together with the spacing formed between the wire rods 10, is sutiicient to permit water to freely escape and return into the bucket when themop is being wrung.
WVringing of the mop is accomplished by inserting the mop material 8 through the opening 7 in the top plate and forcing it downwardly into the wringer. The handle 8a of the mop is at the same time slightly r0- tated and the mop material is thus not only I twisted or wrung but endwise or downward pressure is at the same time exerted, in this manner permitting the mop to bethoroughly wrung. The center portion of the mop material 'is usually the portion which retains the major portion of the water when it is being wrung, but by providing the coneshaped bottom member shown, this projects upwardly into the center portion of the mop material, thus insuring eficient wringing of the same. 4
The use of wireerods in the formation of the body of the wringer 'is'important as they present a corrugated surface whichsecurely grips and holds the mop material while it is being wrung, thus permitting more 0 thorough wringing of the same and reduction of the water content particularly when mopping up or drying the floor after washm it was previously stated that the wringing of the mop was best accomplished not only by rotation of the handle but also by exerting a downward pressure on the same. In view of the downward pressure exerted the wringer as a whole should be rigidly supported, hence the reason for fianging the top plate as indicated at 6. To insure further regidity a bracing arm 14 is employed. This is clear 1y shown in Fig. 2. It is secured at one end to the inner surface of the bucket and at the opposite end to the lower part of the body member, thus rigidly securing the wringer both against twisting action and downward pressure. The forward edge of the plate 6 is preferably provided with a pair of recesses such as shown at 15, one at each side. These serve as a support for the handle of the mop when it is placed in the bucket and as such retains or holds the same in an upright position. The plate 5 may also be provided with drain grooves as shown at 16 so as to catch and return any water which might otherwise spill over during the wringing of the mop.
While certain features of the present invention are more or less specifically described, I wish it understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finish of the several parts employed may besuch as the manufacturer may decide, or varying conditions or uses may demand.
Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A mop wringer comprising a plurality of wire rods having upper and lower ends, said rods being spacedapart and arranged to form an inverted truncated cone-shaped body member, a top plate secured to the upper edge of a pail and to which the upper ends of the rods are secured, said top plate having an opening formed therein to permit insertion of a mop centrally between the wire rods, and a perforated bottom member to which the lower ends of the rods are secured.
rods, and a cone-shaped bottom member to which the lower ends of the wire rods are secured. 7
'3. A mop wringer comprising a plurality of wire rods having upper and lower ends,
said rods being spaced apart and arranged to form an inverted truncated cone-shaped body member, a top plate to which the upper ends of the rods are secured, said top plate having an opening formed therein to permit insertion of a mop centrally between the wire rods and being firmly secured at its outer edges to the edge of a mop pail, and a coneshaped bottom member to which the lower ends of the wire rods are secured, said cone having a plurality of slots formed therein to permit water to be freely discharged when the mop is being wrung.
4. A device of the character described which comprises a substantially triangularshaped pail, a cover plate secured to the up per edges of said pail and covering one corner thereof, an opening in said cover plate, and a plurality of rods extending downwardly and'inwardly from the edge of said opening forming a receptacle in which a mop may be wrun g RALPH H.
