Original Filed June 19, 1951 Aug. 23, 1955 United States Patent O MOPS @lof Gsta Ljungdahl, Lidingo, Sweden Original application .lune 19, 1951, Seriai No. 232,312.5. Divided and this application August 8, 1952, Serial No. 303,213

This application is a divisional of my co-pending application Serial No. 232,325 tiled Iune 19, 1951 and relates to improvements in mops of the kind comprising a sponge member that can be compressed between a pair of plates or similar means for the purpose of removing the water and dirt absorbed by the sponge during use.

The main object of this invention is to provide a mop the sponge of which can easily be mounted and dismounted.

Another object of the invention is to provide a mop that can also be used under low furniture and does not damage it upon coming into contact therewith.

The above-mentioned and other objects and features of the invention as well as advantages thereof will be more readily understood from the following description when taken in connection with the accompanying drawings, in which:

Fig. l is a plan view of the mop proper showing the arrangement of the sponge fastening devices,

Fig. 2 is a section on the line 2-2 of Fig. l,

Fig. 3 is a section on the line 3 3 of Fig. l, and

Fig. 4 is an exploded fragmentary perspective view of the securing means for the sponge.

Referring now to the drawing, which only illustrates a preferred embodiment of the invention, there is shown a cleaning sponge mounted on a support plate consisting of two portions 11a and 11b. To the plate 11a is secured a plate 21 carrying the socket 19 in which the handle 12 lits. To the plate 11b is secured a plate 20 for connection to any suitable means for swinging the said plate to a squeezing position on one or more hinges 13. Glued on top of the sponge and along the long sides thereof are two comparatively narrow rectangular strips 14 consisting of a relatively soft but resistant material, e. g., wood fibre board. The strips extend beyond the outer edges of the support plates, and while effectively stiiening up the sponge, do not damage walls, furniture or other objects with which the mop may come into contact when used. In the strips 14 there are pairs of spaced openings 15 traversed by spaced arms of U-shaped lugs 16. These arms also pass upwardly through overlying openings 15a in the support plates 11a and 11b. The strips 14 are held to the support plates by cotters 17 inserted through holes in the arms of the lugs 16 and arranged so as to be longitudinally slidable. The central portion of each cotter is preferably bent into a U-shaped loop, whereby the handling of the cotters is facilitated. By swinging the loops out of the depressions 18 and sliding them toward the handle 12, they Will be retracted through the ears 16, thus permitting removal of the sponge head from the support plates. As shown in Fig. 1, when the sponge has been attached to its holder plate and the cotters have been slid through the holes in the arms of the lugs the loops are lowered into depressions 18 in the holder plate. Because of that construction it will be feasible to use the implement under very low furniture.

I claim:

1. In a wringer mop, a rectangular sponge7 overlying hinged support plates for the sponge and between which the sponge can be compressed, separate rectangular strips of soft stiif material between the sponge and the support plates glued to the top of the sponge and extending along each longitudinal upper side thereof and extending beyond the outer edges of the support plates, spaced openings in each strip, spaced openings in each support plate, lugs having spaced arms provided with holes for receiving cotters, the arms of the lugs passing upwardly through the openings in each of the strips and the plates, a depression in the plates and cotter pins resting in the depressions and slidable in the holes of the arms of the lugs.

2. The wringer mop of claim 1, in which the cotter pins are partly formed with U-shaped loops and are lowered into the depressions in locking positions.
