Abstract

A wheeled suction nozzle is provided having, generally, a simplified three-piece construction including an upper shell, an intermediate plate and a bottom pan, with the intermediate plate sandwiched between the other two members so that its top surface and the bottom surface of the upper shell form the suction passageways for the nozzle.

A rotary valve is included to activate edge or normal suction, with this valve rotating on a vertical axis and snapfit into position and thus not requiring any sort of connecting means which would positively maintain the rotary valve attached to the nozzle.

Claims

1. A nozzle having an edge cleaning function including;

a. an upper shell member forming at least partially a housing for said nozzle,

b. an intermediate member disposed against said upper shell member,

c. conduit means formed between said upper shell member and said intermediate member for providing for a suction air flow for said edge cleaning function,

d. a bottom plate wear member attached to said upper shell member and sandwiching said intermediate member therebetween,

e. said nozzle also including a conduit means for providing for a suction air flow for a normal forward cleaning function,

f. a rotary valve means providing selective communication with a suction source and one of said conduit means for providing a suction flow of air for selective edge and forward cleaning for said nozzle,

g. said rotary valve means including a rotary valve member that rotates on a generally vertical axis,

h. said rotary valve member being movingly disposed in a means for journalling the same formed by at least partially circular vertically extending walls,

i. terminations of said vertical extending walls providing openings for the passage of a suction flow of air within said nozzle,

j. said rotary valve member including a vertically extending slotted rim, having at least a pair of vertically aligned slots for the passage of a suction flow of air,

k. said openings including at least a pair of front and rear openings formed by terminations of said vertical walls, said front and rear openings also being vertically aligned, and

l. said front opening of said openings formed by terminations of said vertical walls communicating with said conduit means for forward and edge cleaning.

2. The nozzle of claim 1 wherein;

a. at least one of said upper shell member and said intermediate member include said vertically extending walls abutting against the other of said upper shell and intermediate member,

b. said vertically extending walls providing, along with a portion of said upper shell member and said intermediate member, said conduit means for edge cleaning comprising laterally extending passage means for the passage of a suction flow of air and said conduit for forward cleaning comprising forwardly extending passage means for the passage of a suction flow of air.

3. A nozzle having forward and edge cleaning functions including;

a. an upper shell member having a downwardly opening configuration and forming at least partially a housing for said nozzle,

b. an intermediate member disposed below and nested within and against said upper shell member, and providing, generally, a plate-like extent within said open configuration,

c. conduit means for the passage of a suction air flow formed wholly by said upper shell member and said intermediate member including forwardly extending conduit means for forward cleaning and sidewardly extending conduit means for edge cleaning,

d. a generally flat, elongated bottom plate stamping removably attached to said upper shell and closing said downwardly opening configuration and abuttingly holding and sandwiching said intermediate member between it and said upper shell,

e. said bottom plate including (1) an elongated aperture for the passage of a suction air flow for forward cleaning extending substantially from side to side in said bottom plate and (2) at least one aperture disposed in said bottom plate outwardly thereof for the passage of a suction air flow for edge cleaning, and

f. said forwardly extending conduit means communicating with said elongated aperture and said sidewardly extending conduit means communicating with said one aperture.

4. A nozzle utilized for edge and forward cleaning including;

a. a shell member,

b. an intermediate member,

c. a rotary valve member rotatably mounted through the top surface of said shell member and having a vertically extending slotted wall,

d. air flow passageways formed in said nozzle between said shell member and said intermediate member,

e. a bottom plate attached to said shell member and maintaining said intermediate member therebetween,

f. one of said shell member and intermediate member including vertical walls for forming at least a portion of said air flow passageways,

g. said vertical walls terminating adjacent said rotary valve for providing vertically extending apertures,

h. said slots in said wall of said rotary valve member being confrontable with said vertically extending apertures formed by said wall terminations upon rotary manipulation of said valve member, and

i. said rotary valve member extending vertically outwardly above the top surface of said shell member to form a combined dial and valve member for easy top access for said rotary manipulation.
