Application December 8, 1953, Serial No. 396,938

2 Claims. (Cl. 15-138) The instant invention relates to a cleaning and polishing device and more particularly to a floor mop or brush having the cleaning or polishing fluid carried Within a hollow handle thereof, to be dispensed by the user as required.

One of the primary objects of the invention is to provide a floor mop or brush of the character specified in which the cleaning or polishing medium is carried in a replaceable cartridge insertable within the hollow handle of the mop or brush.

Still a further aim is the making of a mop having a replaceable cartridge holding a cleaning or polishing fluid, said cartridge having a valve mechanism readily operable by the user for dispensing the fluid to the cleaning or polishing mop or brush.

Yet another aim is the construction of a device of the type indicated having a perforated dispensing adapter readily attachable to both the handle for feeding the polishing or cleaning medium and to the brush or mop.

An additional purpose is the construction of a cleaning or polishing mop or brush which will simplify the cleaning or polishing of floors; which will aid those allergic to dust; which will eliminate the necessity of applying cleaning or polishing liquid on the floor or to the brush or mop; which is simple in construction and has relatively few parts; and which may be manufactured at a comparatively small cost.

The above and other aims and objects will be apparent from the detailed description hereinafter appearing when taken in conjunction with the appended drawing forming a part hereof and showing a preferred embodiment of the inventionand in which Fig. 1 is a broken side elevational view, partly in section, showing a brush or mop with the cartridge valve in open or dispensing condition.

Fig. 2 is a broken side elevational view of a replaceable cartridge.

Fig. 3 is a top plan view of Fig. 2.

Fig. 4 is a broken vertical sectional view, showing the manner in which the replaceable cartridge is mounted and held within the upper portion of the hollow brush or mop handle.

Fig. 5 is a perspective view showing the manner in which a perforated dispensing adapter may be secured to a brush or mop; and

Fig. 6 is a bottom plan view of the dispensing adapter of Fig. 5.

Referring to the several figures in which like reference characters designate like parts, the cleaning or polishing device is generally designated as D and comprises a hollow handle H, a replaceable cartridge C, a perforated adapter A and a brush or mop B.

The hollow handle H which may be of any desired length of tubular metal or plastic is provided adjacent the upper end thereof with an external thread 10. Cartridge C comprises a cylindrical hollow main body portion 11 of a size to hold an adequate quantity of cleaning or polishing fluid. The lower section 12 of the cartridge is provided with an integral internal centrally perforated seat 13, said seat being externally threaded at 14 for removably receiving the internally threaded end 15 of a tapered tip or nozzle 16 opens as at 17. Upper half 18 of the cartridge C has an inwardly extending integral centrally perforated seat 19 supporting an axially apertured disc 20; said upper half 18 being externally threaded at 21, see Fig. 4. An elongated valve rod or stem 22 has one end thereof projecting through the aperture in disc 20, said rod terminating in a flattened head 23. Surrounding the upper terminal portion of stem 22 and resting on disc 20 is a coil spring 24; the flattened head 23 of the stem tightly fitting into and securely held within a recess 25 of a dispensing button 26, which in turn is held in place by a thin sleeve 27 internally threaded at 28 for engagement with the external threaded end 21 of the upper section of the cartridge body 11. Sleeve 27 has a central opening 29 through which button 26 extends, said button having an internal annular flange 30 adapted to abut the inner surface of the sleeve. Valve stem 22 is threaded as at 31 for removable connection to valve disc 32 having a threaded opening 33.

It is intended that cartridge C hold a quantity of cleaning or polishing liquid to be sold as a unit. The cost of the dispensing valve mechanism embodied in each unit should be relatively small as compared to the cost of the liquid contained Within the cartridge. However, if desired, the single cartridge may be refilled with a cleaning or polishing liquid for reuse, in a manner which will be more fully described hereinafter.

The cartridge C is placed within the upper portion of hollow handle H, whereby the lower edge of sleeve 21 rests on the upper edge of the handlesee Fig. 4. Pinally, a thin internally threaded handle sleeve 34, similar to sleeve 27, threadedly engages external threads 10 of the handle with button 26 loosely extending through a central opening 35 in said handle sleeve. It will now be seen that the cartridge is operatively held Within the handle.

Hollow handle H is internally threaded at its lower end as at 36 for the reception of the perforated hollow dispensing adapter A. The latter comprises a perforated bottom wall 37, curved perforated side and upper walls 38 forming a hollow container and a neck 39 externally threaded for engagement with the internal threads 36 of the hollow handle.

A cleaning member comprising a brush or mop B is characterized by a cloth head 40 holding bristles or mop strands 41. It will be noted that head 40 has oppositely disposed spaced cloth pockets 42 and 43 into which the dispensing adapter is to be inserted in the manner illustrated in Fig. 5, one end of the adapter being first inserted into one of the pockets 42 or 43, and then into the other, the pockets being sufliciently stretchable to permit this.

From the above description, it will be seen that the cartridge C and its valve mechanism, filled with cleaning or polishing liquid, may be sold as a unit, and after insertion into the upper portion of handle H, is secured in position by means of threaded sleeve 34. In this position, the cleaning or polishing device D may be moved along the floor or other surface with brush or mop B in contact therewith. The user now depresses button 26 against action of spring 24, thus forcing valve disc 32 from its seat as in Fig. 4, to the position of Fig. 1, whereby the liquid will flow downwardly into the adapter A which distributes same by virtue of its perforations through porous cloth head 40 to the bristles or mop strands 41. Release of pressure on button 26 obviously stops the flow. While it is contemplated that cartridge C with its valve mechanism be sold as a unit and replaced in toto when all polishing or cleaning liquid has been used up,

yet it is possible to refill the cartridge by removing same from handle H, unscrewing tip or nozzle 16 and valve disc 32, inverting the cartridge and filling same through the central opening in seat 13.

It will be understood that various minor changes maybe made in the specific disclosure and it is contemplated to cover all such and to be limited in this respect only as maybe necessary by the scope of the claims hereto appended.

What we claim and desire to secure by Letters Patent 1. A cleaning or polishing device comprising a tubular handle open at opposite ends, a cleaning member, means for securing said cleaning. member to the lower end of the handle, the upper end of. the handle being externally threaded, a replaceable. cartridge insertable into the upper end of the handle, said cartridge having a valve mechanism and a button for operating said mechanism, an external sleeve secured to said cartridge holding said mechanism with said cartridge, said sleeve resting on the upper edge of said handle, and a centrally apertured second internally threaded. sleeve adapted to hold said cartridge Within said handle by engagement with the external threads of the upper end of said handle.

2. The structure of claim 1, in which said means for securing the cleaning member to the lower end of the handle comprises providing said lower end with a threaded portion, said cleaning member including a head having oppositely disposed spaced pockets, a hollow adapter having a perforated bottom wall, curved side and upper walls and a threaded neck, said adapter being inserted into said pockets by virtue of the space therebetween, said threaded neck being in removable threaded engage ment with the threaded lower portion of said handle.
