Because the side surfaces 22,24 and the inner surface 44 are tapered, and because the inner surfaces 46, 48 are undercut to accomodate outwardly directed flanges 49 at the top of each side surface 22,24 the tank 32 is securely removably retained by gravity on the nozzle 18. If necessary or desirable, one or more fastening devices may be used to secure the tank 32 to the nozzle 18, although the tank 32 is preferably easily removable from the nozzle 18 so that filling of the tank 32 with cleaning solution is facilitated.
The tank 32 is hollow and includes a fill cap 50 which is insertable into an opening of the tank.
The spray nozzle 34 is secured to the second surface 26 by any appropriate means, such as a screw. The tube 36 is connected at opposite ends thereof to the tank 32 and the spray nozzle 34.
The assembly is prepared for use by removing the tank 32 from the nozzle 18 and removing the fill cap 50 from the opening. The tank 32 is then filled with cleaning fluid PATENT APPLICATION
21 8~ 515 through the opening, the fill cap 50 is replaced in the opening and the tank 32 is mounted on the nozzle 18. During operation of the vacuum cleaner 10, cleaning fluid may be sprayed on a surface to be cleaned by manually pumping the spray nozzle 34 and the fluid may be picked up by the suction at the inlet end 28 of the nozzle 18.
If desired, the assembly may utilize a differently shaped tank for use on other types of nozzles.
Numerous modifications and alternative embodiments of the invention will be apparent to those skilled in the art in view of the foregoing descriptian. Accordingly, this description is to be construed as illustrative only and is for the purpose of teaching those skilled in the' art the best mode of carrying out the invention. The details of the structure may be varied substantially without departing from the spirit of the invention, and the exclusive use of all modifications which come within the scope of the appended claims is re-served.
