4 Claims. (Cl. 285-975 The present invention relates to new and novel improvements in a surface-cleaning tool adapted for use with suction cleaners.
An object of the invention is to provide a new and improved surface-cleaning tool. Another object is to provide a cleaning tool having a resilient body for attaching thereto a brush and a conduit. Another object is to provide a swivel joint between a conduit and the cleaning tool. A further object is to provide a cleaning tool having a resilient body which acts to secure thereto a swivel joint. Other objects and advantages of the invention will be apparent from the following specification and drawings wherein:
Figure 1 is a top plan View partly in section of the cleaning-tool;
Figure 2 is a front view partly in section;
Figure 3 is a section along the line 3-3 of Figure 2; I
Figure 4 is a section along the line 4-4 of Figure 2; and
Figure 5 is a section along the line 5-5 of Figure 2.
The cleaning tool herein disclosed is of the type adapted to be connected at one end of a dusting tool hose which is secured to a suction cleaner. The nozzle includes an upper body portion I formed of a molded resilient rubber or plastic to which is attached a lower body portion 1 I forming a brush assembly. The resilient por tion It comprises an integrall formed socket I2 having an arcuate side wall I3 and a front wall I4, both of which merge with an elongated top wall I having a depending peripheral side wall I6 terminating in an inwardly projecting shoulder I! which cooperates with the side wall I6 and the adjacent edge portion I8 of top wall I5 to form a channel-shaped seat or recess I9 extending along the side wall I6.
The brush assembly II includes an elongated brush back or frame having a peripheral shoulder 2| from which extends a solid portion 22 of the brush back II. Formed in the solid portion 22 and spaced from the opposite ends thereof is an air passageway 23 having a relatively large inlet 24 in the bottom face of the brush back and terminates in a restricted outlet 25 in the top of the brush back for connection with a chamber 20 in the upper body portion I0. Secured in the shoulder 2| is a brush formed of two rows of bristles 26 and 21 arranged in staggered relation so that the bristles overlap each other, and thus form an elongated opening 28 communicating with the relatively restricted inlet 24. The brush back is removably attached to the resilient 2 a body portion II! by inserting the shoulder 2| in the recess I9, and is retained in position by the coaction of the flange I1 and the opposite portion I8 of the top wall I5. Depending from the top wall I5 of the body portion .I0 are a plurality of spaced ribs 29 which abut the top surface 30 of the brush back.
A swivel joint is provided between the socket I2 and an angular conduit 4|, the latter being adapted to receive one end of an unshown hose, the opposite end of which is connected to a'suction cleaner. The swivel joint comprises a pair of semi-cylindrical metal members 42 and 43,
each of which has its opposite ends 44 in abutting engagement to form a cylindrical member having an outside diameter slightly larger than the in side diameter of the socket I2 so that the latter frictionally secures the members 42 and 43 against rotation. Longitudinal movement between the socket I2 and the members 42 and 43 is prevented by providing flanges 45 and 46 on the opposite arcuate ends of the members, the flanges 45 abutting a shoulder 41 on the socket I2 and the flanges 46 abutting the extreme end 48 of the socket I2.
Rotatably mounted within the members 42 and 43 is a reduced portion 49 of the conduit 4| and is provided with spaced shoulders 50 and 5| which respectively abut the flanges 45 and 46 on the members 42 and 43 to prevent longitudinal movement therebetween.
In assembling the swivel joint 40 the semicylindrical members 42 and 43 are arranged about the reduced conduit portion 49 between the shoulders 50 and 5| to form a cylindrical surface,
7. and the resilient socket I2 is then stretched over the members 42 and 43 into abutment with the flanges 45 and 46 to join the parts together. In rotating the conduit 4| with respect to the nozzle the reduced conduit portion 49 rotates with respect to the two members 42 and 43 and the latter are non-rotatable due to their frictional engagement with the interior surface of the socket I2. f H 25 51a In using the cleaning tool air is drawn ttieri through by suitable unshown suction-creating means connected to an unshown hose joined to the conduit 4|. The operator moves the nozzle over the covering to be cleaned with the bristles 26 and 21 in contact with the covering to dislodge the dirt into the air stream, and the dirt-laden air stream passes through the elongated brush inlet 28, restricted nozzle inlet 24, air passageway 23 and the outlet 25 into the chamber 20, and then passes through the conduit 4|.
