1 Claim.
This invention relates to a wringer mop.
One object of the invention is to provide a mop having a wringing attachment so arranged that the pressure applied tothe mopping material in the wringing operation increases progressively as the operation itself progresses from the attached end to the free end of the mopping material.
Another object of the invention is to pro-vide a wringer mop structure in which the mopping material is attached to one of the wringer rolls and said roll is so formed that said material may be easily and conveniently attached thereto without danger of damage to the iloor by the attaching means.
Another object of the invention is to provide a wringer mop structure which is of light construction and easily handled.
Another object of the invention is to provide a wringer mop structure in which the mop material is attached to one of the wringer rolls and said roll serves as a reservoir for a supply of water for the mopping operation.
Other objects of the invention and the full nature thereof will be apparent from the accompanying drawing and the following description and claim:
Fig. 1 is a perspective view of a wringer mop constructed in accordance with the invention. Fig. 2 is a sectional view of one end of one of the wringer rolls.
In the form of the invention shown in the drawing, there is provided a mop handle Il) whichrmay be threaded in a socket II, or otherwise attached to said socket. The socket II is formed on a yoke member I2 having a pair of parallel arms I3, in the lower end of which there is journaled a wringer roll I4. Said roll has secured thereto a crank I5 having a handle I5 by means of which the roll may be rotated. A second wringer roll I1 is mounted on suitable trunnions operating in slots I8 in the legs I3 of the yoke member. A frame I9, preferably formed of relatively heavy wire, engages the trunnions of the roll II and is secured thereto by trunnion screws 20. The wire frame I9 has a portion 2l loosely wrapped about the socket II and engaged by a compression spring 22 surrounding sai-d socket. Said spring abuts against a washer 23 secured to the socket by a Cotter pin 2t. By means of this construction, the spring 22 presses the frame I9 and roller I'I downwardly and maintains the roller I'I in contact with the face of the roller Iii. A keeper 25 is provided with a coil spring portion 26 `surrounding a part of the wire frame I9 and with a hooked portion 21 engaging the crank I5 to maintain the parts in the position shown in Fig. 1 while the device is in use as a mop. an upstanding portion 28 which may be pressed to the left in Fig. 1 against the action of the spring portion 26 to free the crank from the keeper.
The wringer roll I4 is formed with a spiral cross section having a substantially radial face 29 connecting the inner portion 30 and the outer portion 3l of the spiral. Mop material 32, which may be either cord or fabric, is secured to the radial face 29 in any suitable manner.
The roll I4 is preferably hollow in construction and may be formed of sheet metal as shown in Fig. 2. In the form shown in that ligure there is provided an opening 33 which is closed by a ring 34 welded thereto and provided with a threaded opening in turn closed by a plug 35. The plug 35 may be removed for filling the roll with water. In the radial face 29 there are provided a plurality of small apertures 36 through which the water may escape for wetting the mopping material 32.
In the use of the device as a mop the parts are held in the position shown in Fig. 1 by the keeper 25. When applied to the floor the inner portion 30 of the spiral face of the roller I4 rests on` the mop material. The point of attachment of the mop material -to the roll is protected against contact with the floor by the shaping of the radial face 29. Whatever fastening means are used to attach the mop material does not come in contact with the floor. Damage to the floor due to scratching by such fastening means is thereby prevented.
When the mop is to be wrung out, the keeper 25 is operated `to freethe crank I5 and the crank is turned in the direction of the arrow in Fig. 1. In this movement the portion of the mop material adjacent its point of attachment is rst engaged between the rollers and-this portion rides on the inner part 30 of the spiral surface. As the turning of the roll progresses, the shape of the spiral is such that the roll I1 is forced upwardly against the pressure of the spring 22 and the consequent compression of the spring increases the pressure. The mop material 32 has a length substantially equal to or slightly less than the spiral perimeter of the roll I4 so that the free end of the mop material rides on the outer portion 3l of the spiral surface as it passes between the rolls.
lThe keeper is provided with At this point the pressure of the spring 22 is a maximum and at this point also there is the greatest accumulation of water to be wrung out and the greatest amount of dirt in the mop material to be washed out by the water. Thus, the eonstruction provides for maximum wringing pressure at the point where it is most needed whereas in other portions of the wringing operation a less pressure is applied. In that portion Where the maximum pressure is not needed the crank I5 is comparatively easy to turn and the maximum resistance to turning only occurs where maximum pressure is required.
The invention has been described in one of its preferred forms, the details of which may be varied without departing from the scope thereof as defined by the appended claim.
The invention claimed is:
In a wringer mop, `a roller of spiral cross section having a radially extending face joining inner and outer portions of the spiral, Inopping material secured to said radial face, a second roller yieldingly engaging said rst roller, and means for rotating said rst roller to pass said mop material between said rollers, said spiral roller being hollow and adapted to contain a supply of water, and said radial face having orices for delivery of said water to said mopping material.
