Description

Patented Mar. 3, 1942 warren srrs 3 Claims.

This invention relates to a wringer mop of the general type disclosed in myco-pending application, Serial No. 3G7,306-, filed December 2,- 1939;

One object of-tlfe present invention is to pro- In the type of wringer mop to which the pres- I cut invention pertains, the mopping material is secured to a roller and a second roller parallel with the first is provided. The second roller is yieldingly urged toward the first and the first roller is rotatable to pass the mopping material between the rollers for wringing the same. In my prior-application mentioned above, there is provided a roller of spiral cross section to which the mopping material is attached and which, because of its specific cross section, increases the wringing pressure toward the tip of the mopping material. In the present invention, similar results are obtained by an improved form of construction in which the roller itself is cylindrical and may thus be turned on a lathe, the additional squeezing effect required at the tip of the mop ping material being provided by adding to the roller a protuberance in the form of a piece of curved sheet metal properly shaped to give the desired result.

In my prior application there is disclosed guard means formed on the frame of the structure to prevent the mopping material from fouling the 5 bearings of the rollers. In the present invention the same result is obtained in a simpler manner by the provision of constraining means of a different type.

Other objects and features of the invention will be understood from the accompanying drawing and the following description and claims:

Fig. l is a side view of a wringermop constructed in accordance with my invention. Fig. 2 is a view of the underside thereof.

In the preferred form of the invention shown by way of illustration in the drawing, there is provided a U-shaped frame structure It] having downwardly projecting legs H and a ferrule 12 adapted to receive a mop handle 13 which may be of any suitable length. A roller M of cylindrical cross section has one and provided with a screw l5 journaled in one of the legs I l and providing a bearing for said roller. A crank I6 is provided with a squared shank l1 projecting into WRINGER Mor Gilbert-E. Bodimer, Indianapolis, Ind.. Application October 10, 1940, Serial No..360, 521- a suitable squared hole centrally disposed in the roller [4. Said crank is provided with a rounded portion [8 journaled in the second of the legs I l and'is provided with a'knob lefor rotating the same.

A curved piece of sheet metal the shape of which isbest seen in 1, extends longitudinally along the roller ii: 'One edge. of said-sheet metal is securedtothe roller l i as byf s'crewsZ l and forms a forward face "22ofrelatively gentle slope and substantially continuous with the surface of the roller [2. The opposite edge of the piece 20 is curved at a steeper angle and is inset in a groove 23 in the roller I l. This portion of the piece 29 forms a rear face 24 having a steeper slope than the forward face 22 and intersecting the surface of the roller M at arelatively sharp angle. Mopping material 25 is provided and may be formed of fabric, cord or any other suitable,

material. One end 26 of said material is provided with a fabric sheath 2'! which is secured to the roller M by means of screws 28 passing through the rear face 24 of the piece 29 and into the roller I4.

In order to restrain the edges 28 of the mopping material and prevent the same from working into the spaces between the ends of the roller 14 and the legs I! of the frame, there are provided a pair of constraining bands 38. Each of said bands is preferably endlessin form and passes about the sheath 27 adjacent the center thereof. Each of the bands 30is thus secured inposition when the mopping material is secured A second cylindrical roller 3| i arranged in parallel relation with the roller l4 and is provided with screws 32 axially arranged and journaled in the ends of torsion springs 33. The 0pposite end of each spring 33 passes through a suitable opening in the associated leg H and is curved about the frame [0 as shown at 34. Said springs urge the roller 3| toward the roller l4 and provide the necessary pressure for'wringing the mop material between said rollers. able detent, preferably in the form of a flexible A suit- I member 35 engaging the crank arm 16, is provided to retain said crank arm in the position shown during the use of the mop.

In the wringing operation the detent 35 is released by pressing the same inwardly and the crank I6 is turned in the direction of the arrow in Fig. 1. The mopping material is thus passed between the rollers 3| and Hi, the unsecured end 36 thereof passing between the roller 3| and the protuberance formed by the member 20. This portion of the material contains a large part of the water squeezed from the remainder of the material and requires the greater pressure to remove this water. The greater pressure is provided by the greater flexing of the springs 33 as the roller 3| rides on the forward face 22 of said member. The member 20 thus provides a similar wringing action to that of the spiral roller disclosed in my co-pending application before mentioned but the construction thereof is much simpler and the manufacturing cost and weight of the mop is greatly reduced. The provision of the constraining bands 30, the weight of which is practically negligible, obviates the necessity of adding metallic guards of any type to the frame structure or to the roller itself.

The invention has been described in one of its preferred forms, the details of which may be varied by those skilled in the art without departing from the scope of the invention as defined by the appended claims.

The invention claimed is:

1. In a wringer mop, a rotatable roller, mopping material having one end secured thereto, a second roller parallel with said first roller and yieldingly urged toward the same for wringing said mopping material therebetween, and flexible constraining bands secured adjacent the center of the secured end of said mopping material and extending diagonally downward and outward about the edges of said material on both sides thereof. I

2. In a wringer mop, a rotatable roller, mopping material having one end secured thereto, a second roller parallel with said first roller and yieldingly urged toward the same for wringing said mopping material therebetween, and flexible constraining bands secured adjacent the secured end of said mopping material and extending diagonally away from said end and about the edges of said material on both sides thereof.

3. In a wringer mop, a rotatable roller, mopping material having one end secured thereto, a second roller parallel with said first roller and yieldingly urged toward the same for wringing said mopping material therebetween, and constraining means secured adjacent the center of the secured end of said mopping material and embracing the edges of said material at points remote from said secured end.
