Patented Julyl5, 1341 UNITED STATES PATENT OFFICE SUCTION NozzLE Ralph E. Dunbar, East Cleveland, Ohio, assignor to Electric Vacuumv Cleaner Company, Inc" Cleveland, Ohio, a corporation of New York Application July 21, 1939, Serial No. 285,709
' 1 Claim. (01. 15-158) what I believe novel and my invention, attention is directed to the following description and the claim appended thereto.
In the accompanying drawing Fig. 1 is a per-' spective view of a suction nozzle embodying my invention; Fig. 2 is a side elevation; Fig. 3 is a rear elevation; and Fig. 4 is a perspective view of the bottom of the nozzle.
Referring 'to the drawing, there is shown a suction nozzle I having'front and rear surface contacting lips 2 and 3. As shown in Fig. 3, the ends of the nozzle lips are lowerthan the intermediate portions. Accordingly the intermediate portions of the nozzle lips are supported slightly above the surface being cleaned. If the nozzle is used for cleaning afloor covering, the floor covering will therefore be raised from the floor against the intermediate portions of the nozzle lips and will be subjected to a flexing action as the nozzle is moved across the floor covering. I On the rear side of the nozzle is a downwardly facing recess defined by end walls 4 and top and rear walls 5 integral with the nozzle. The
, recess extends only along the intermediate part of the nozzle. In the recess is a brush 8 mounted in the manner shown in my application Serial No. 164,369; filed September 17, 1937, now Patent 2,205,877. As disclosed in this application, the
7 vertical position of the brush is adjusted by a.
screw 1 extending through a cam. slot 8 in the wall 5. At the ends of the suction nozzle are areuate shoes 9. extending rearwardly and upwardly from the rear nozzle lips 3. The shoes .are integral with the rear nozzle lips and the end walls 4, and from one aspect constitute. a
fillet between the rear nozzle lips and the ends of the recess. As shown in Fig. 2, the lower end of the brush is above the plane of the shoes adjacent the rear nozzle lip and below the plane of the rear ends of they shoes. Accordingly, when the nozzle is rocked or tilted on the shoes the brush is brought into engagement with the floor covering. At the same timethe front and rear nozzle lips are raised to permit a greater admission .of air between the floor covering and the nozzle lips which will entrain the dirt removed from the floor covering by the agitation of the brush 6. The shoes 9 being in contact with the floor covering restrict the air flow to the suction 1 over the surface being cleaned. Under normal conditions the nozzle is supported on the floor covering by .the nozzle lips 2 and 3 and the shoes 9 are slightly above the floor covering. In this condition the brush either bears lightly on or is slightly above the surface, of the floor. covering.
This is the condition most effective for normal cleaning. If an exceptionally dirty spot /is encountered-the suction tube I2 is lowered, rocking the'nozzle on the shoes 9 and bringing the brush into engagement with the floor covering. This subjects the floor covering to a scrubbing' action, and the dirt loosened by this action is 'more easily drawn into the suction nozzle due to the large air flow caused byzthe raising of the front and rear-nozzle lips. During normal cleaning the front ends of the shoes contact the floor covering, and in deep pile carpets the nozzle lips may sink into the pile of the carpet so that the nozzle will be partially supported on the arcuate surfaces of the shoes. This makes the nozzle somewhateasier to push.
What I claim as new and desire to secure by Letters Patent of the United States is:
In a vacuum cleaner, a suction nozzle having 'front and rear surface engaging lips and provisions for connection with a suction tube which shoes and in front of the rear ends of the shoes,
said brush projecting below the plane of said intermediate portions of the shoes but not to the plane of the front ends of the shoes whereby the brush engages the surface being cleaned when raisethe nozzle lips.
the nozzle is tilted rearwardly on said shoes to RALFH E." DIJNB'AR.
