Description
M. HEBER MOP WRINGER Sept. 11, 1951 Filed March 29, 1948 Patented Sept. 1951 Michael Heber, deceased, late of San Jose, Calif., by Elma Recksiek, executrix, San Jose, Calif., assignor to Helene H. Armstrong, San Fran= cisco, Calif.
Application March 29, 1948, Serial No. 17,602
3 Claims.
The invention relates to devices for wringing wet mops and more particularly to the type of device generally characterized as a conically shaped perforated receptacle mounted on the inside of a pail and into which the mop is lowered, rotated and compressed so as to wring water therefrom.
An object of the invention is to provide a device of the character described wherein the receptacle perforations are formed in such a manner as to coact with and to increase the intensity of the compression and wring actions above noted in addition to their function as water escape openings, whereby the device will produce a dryer mop with less manual effort than heretofore.
Another object of the invention is to provide a mop wringing device of the character above which may be easily and quickly attached and detached from the rim of any standard mop pail and which when attached will be rigidly anchored to the pail and capable of receiving the full force of the mop compression and rotation without slipping, loosening, or falling relative to the pail.
A further object of the invention is to provide a device of the character described, which is ruggedly constructed to withstand hard usage for a very long period of time, yet designed with a minimum amount of relatively light weight material and of a form adaptable to mass inexpensive production.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that Variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in the claims.
Referring to said drawing:
Figure 1 is a plan view of a mop-wringer incorporating the present invention.
Figure 2 is a cross sectional view of the mopwringer taken substantially on the plane of line 2-2 of Figure 1.
vFigure 3 is a fragmentary cross sectional view taken substantially onthe plane of line 3-3 of Figure 2.
Figure 4 is a side elevation of the device.
The mop wringer of the present invention and as depicted in the accompanying drawing comprises, an open topped receptacle 6 adapted for mounting on the rim 'I of a mop pail 8 so as to lie within the pail for receipt of a wet mop which is lowered into the receptacle and rotated and compressed therein to wring out the water content of the mop. As will be seen from the drawing the receptacle 6 is composed of a ring like top portion 9, preferably of circular formas here shown, and a plurality of circumferentially spaced ribs II which are formed integrally with the top portion and depend therefrom to a disc shaped bottom I2, also preferably integrally formed with the ribs and the top ring portion.
As an important feature of the present invention, the bottom I2 is of smaller diameter than the top ring 9 and generally axially aligned therewith, and the ribs II converge relative to each other and to the axis in a downward direction from the top to the bottom of the receptacle. In this manner the side wall enclosure for the receptacle defined by the spaced ribs is of conical shape, tapering toward the bottom, so as to confine and compress the mop as it is pressed downwardly into the receptacle. The water thus squeezed from the mop escapes through the side openings I3 defined between the ribs and through a bottom opening I4 provided centrally in the bottom disc I2 for discharge into the pail 8. Also in this construction and as a particularly important feature thereof, the openings I3 dened between the ribs are vertically elongated and eX- tend for substantially the full heighth of the receptacle and are wedge shaped, tapering approximately uniformly toward the bottom. In this manner portions of the mop entering the openings I3 adjacent their enlarged upper ends are compressed tightly together as such portions are forced downwardly in the tapered openings as the mop is pressed into the receptacle. Preferably the mop is rotated as it is pressed into the receptacle so that the free water at the center of the mop is wrung or squeezed outwardly to the peripheral portions of the mop which are further wrung or squeezed in the tapered openings as above described. In this manner a very effective and double wringing action is obtained. Of importance also is the full continuity of the openings from the top to the bottom of the receptacle so that a progressive wedging of the mop portions entering the openings is obtained over the full heighth of the receptacle. In this manner the operator can control the wringing action by the extent of insertion of the mop into the receptacle and at the selection of the operator a relatively wet or a relatively dry mop can be produced.
Preferably' the bottom I2 of the receptacle is dish shaped and arranged with its concave surface upward and is joined to the lower ends of the ribs II in a smooth curved configuration. To accomplish this smooth curved joinder of the ribs and the bottom, the ribs are preferably curved inwardly adjacent their lower ends so as to merge smoothly into the shaped dish bottom. In this manner the mop inserted into the receptacle is fully compressed at the bottom of the receptacle and there are no square corners at the receptacle bottom into which the lower end of the mop might escape compression action. Desirably the opening I4 provided centrally of the base I2 is of substantial size so as to effectively drain olif the` water deposited on the bottom I2, and the dish shape of the bottom insures a running oir of the water into the escape opening Iii.
As a means for correctly positioning the device within a standard mop pail, ribs IIa and Hb which are spaced circumferentially a substantial distance from each other are formed with integral radially outwardly extending v:Jebs it and I1 which are arranged to engage the inside surface of the pail side wall I8. The upper ends of the web I6 and I1 are formed with lateral projections I9 and 2| which are formed to engage over the top rim of the pail and the outer edges 22 and 23 of the webs depending from the projection I and 2| are tapered slightly with respect to the central axis of the receptacle in general conformance with the taper provided on the side wall I8 of the standard mop pail. As will be seen from the drawing the outer edges 22 and 23 of the webs extend in straight lines over the majority of the heighth of the receptacle as to provide a full bearing support of the receptacle against the side wall of the pail. Due to the tapered form of the webs I8 and ll, the receptacle is properly supported in upright position that is with its central axis vertically disposed when the receptacle is mounted in a standard mop pail as here shown having a tapered side wall I8.
To securely fasten the receptacle to the mop pail, there is provided at the top 9, and preferably integrally formed therewith, approximately midway between ribs IG and I'I, a lateral projection 24 adapted for positioning upon the top rim 'I of the pail and being preferably formed, as here shown, with a depending outer i. A leaf spring 2'! is secured at one end 23 thereof to the underside of the projection 2l and within the depending ilange 2G. The opposite end portion 29 of the spring is formed to resiliently engage the exterior surface of the side wall i8 of the pail to thus draw the webs I6 and Il' tightly against the inside surface of the pail side wall. The spring end 23 may be secured to the projection 24 in any suitable manner such as means of the nut and bolt 3l mounted through the projection 2.-'l and the inturned end 23 of the spring. The fastening of the spring in this manner leaves the exterior surface of the depending flange 2 entirelf,7 free from any obstructions and with only the bolt head showing above the projection 2li.
As will be understood the receptacle may be simply and quickly applied to a standard mop gia-il by inserting the receptacle into the open tof: of the l with the .webs t6 and Il' against the inside surface of the pail sidewall, and bv delecting the spring El' radially outward to engage the outside surface of the pail side wall.
The receptacle may then be pressed downwardly into the pail until the lateral projections I9 and 2l on the webs and projection 2li on the top ring of the receptacle seat firmly upon the rim l of the pail. In this position the pail side wall is strongly gripped between the spring and the webs and the receptacle is thus firmly anchored in place and prevented from slippingL loosening, twisting, or otherwise moving relative to the pail when the mop is pressed into the receptacle for wringing, or when the bucket is handled for relling, carrying about, or emptying.
Preferably the entire receptacle including the top portion 9, ribs II, bottom I2, webs I6 and I'l, and the projection and ilange 24 and 26 are formed of a single unitary material as by casting. Any strong and lasting material adaptable for die-casting suoli as aluminum, or copper-zinc alloy may be used. The unitary construction of the design above described affords an extremely rugged device capable of withstanding hard usage over a substantially unlimited period of time, and yet due to the open design of the unit, it is relatively light in weight and easily handled and applied to the mop pail.
