' 2 Claims. I
The present invention relates to a surfacecleaning tool adapted for use with suction cleaners.
An object of the invention is to provide a new and improved cleaning tool. Another object is to provide a cleaning tool having a brush removable independently of the nozzle lip for access to a swivel joint between the cleaning tool and a hose connected to a suction cleaner. Other objects and advantages of the invention will be apparent from the following specification and drawings, wherein:
Figure l is a rear view partly in section of the cleaning tool;
Figure 2 is a top plane view;
Figure 3 is a front View partly in section;
Figure 4 is a section along the line 4-4 in Figure 3;
Figure 5 is a section along the line 55 in Figure 4, showing one adjusted position of the brush;
and
Figure 6 is similar to Figure 5, but showing the brush reversed to another adjusted position.
The embodiment of the invention herein disclosed comprises a nozzle having a body formed of a cast metal upper portion In and a lower portion ll formed of a metal stamping. The upper portion H! of the nozzle includes a top wall l2, front wall l3, opposite end walls I l-l4 and a rear wall 15, the latter at its central portion having spaced side walls l6 and H and end walls [8-48 defining respectively the front, rear and end walls of a brush housing l9. Depending from the top wall I2 is a semi-circular wall which defines in part an outlet 2| to socket 22 formed above the brush housing is for receiving a conduit 23 which is adapted to be connected to an unshown hose having its opposite end connected to suction-creating means in a manner well known in the art.
The lower portion ll of the nozzle body has a front lip 25 and a rear lip 26 which merge at their opposite ends into nozzle end lips 2|-2'l, and the lips 25, 26 and 2! cooperate to define a suction nozzle inlet 28. The surf-aces of the end lips 2'l21 and a portion 29 of the opposite ends of the front. and rear nozzle lips form supporting surfaces or shoes which lie in a plane lower than the intermediate portions of the front and rear lips. The rear lip 26 slopes upwardly and rearwardly, while the end lips 21-21 and the adjacent portions 29 are convexed for inclining the nozzle rearwardly during cleaning operation.
The rear nozzle lip 26 is provided with an upstanding flange 30 extending throughout the length of the nozzle, and a portion 3! of the flange 3B abuts the lower edge 32 of the front wall E6 of the brush housing l9. Extending laterally of the flange 3d at opposite ends of the brush housing 19 are spaced shoulders 3535 each of which has an upstanding rear flange 36 abutting the lower edge of the rear wall I! of the upper body portion 5!]. Each of the shoulders iii-$5 is arched upwardly from the end lips 2'5-2'5 and terminates at the end walls l5--l8 of the brush housing is in the upper nozzle portion lil. Proiecting upwardly from the front lip 25 and the end lips 212'l is a flange 38 which merges into the rear flange 35 and the flange 38 abuts the front wall 13 and end walls I i-l4 of the upper nozzle portion 18. A suction air passageway 4%?! is formed by an upstanding front wall 41, a rear wall 32 and a top wall :3, the latter having a central flat portion M. A portion of the rear wall 42 and the flat top portion 44 is cut away to cooperate with the semi-circular wall 20 in upper body portion Hi to form an outlet 45 from the suction air passageway 49 to the angular conduit 23. The portions Hi and II of the nozzle body are removably attached together by a plurality of screws 41 threaded into lugs 48 depending from the top wall I2.
A furniture guard 55 of rubber or other suitable material is arranged along the front wall, the ends of the top wall and rear wall of the nozzle, and is provided with a plurality of spaced lugs 5! which are inserted in marginal slots 52 formed in the lower edges of the walls of the upper nozzle portion it. And the outer upstanding flanges and 35 of the lower nozzle body portion H abut the lugs 5! to secure the furniture guard in position.
The brush housing I9 is completely arranged in the upper nozzle body portion l0 and is defined at its top by a bottom wall 55 of the socket 22 and walls 555B extending from the socket 22 to the housing end walls 18-48.
Arranged in the brush housing I9 is an elongated brush back 5!] of brush BI and in which are seated tufts or bristles 62. Formed on the brush back 6!] are lugs 63 and 64 which are spaced an unequal distance from the opposite ends of the back 66 for optional abutment against seats 65 and 65 depending from the top wall 56 of the brush housing. When the bristles 62 are new, the brush back is inserted in the brush housing is so that the back 60 abuts the fiat wall 55 and the lugs 63 and 64 are out of alignment respectively with the seats 65 and 66, and the brush is held in position by a screw 68 threaded into the wall of the socket 22. After the brush bristles 62 have become Worn, the brush is adjusted by reversing the brush back 60 so that the lugs 63 and 64' abut the seats 65 and 66 respectively.
A swivel joint between the socket 22 and the conduit 23 comprises a U-shaped locking member 'H having its bight portion 12 seated in a recess 13 in the fiat socket wall 55. Legs 14-14 of the member II project upwardly through holes 15-15 into an annular groove 16 in the exterior surface of the portion 11 of the conduit 23 to permit the latter to be rotated with respect to the nozzle and prevent longitudinal displacement with respect to the nozzle. The locking member is held in position by the brush back 55 as shown in Figure 4.
In operation, the conduit 23 is connected to an unshown hose, the opposite end of which is connected to a source of suction to create suction in the nozzle inlet 28. The nozzle lips 25-26 and 21 glide along the surface being cleaned and dirtladen air is drawn through the suction inlet 28, suction passageway 49, outlet 46 and the conduit 23 to an unshown dirt filter. It will be noted that the suction air passageway 40 is substantially triangular in cross-section transversely of the nozzle in that its top wall 43 converges uniformly toward the outlet 49 to provide a smooth interior for passage of the dirt-laden air.
When it is desired to brush the surface being cleaned, the operator depresses the conduit 23 to rotate the nozzle about the convex shoes 29-29 to place the bristles 62 into engagement with the surface being cleaned, so that the dirt is loosened and then removed by the suction in the nozzle inlet 28. After the brush has been used for a considerable time and the bristles 52 have become worn and they no longer engage the surface being cleaned, it is desirabl to adjust the brush so that the original extension of the bristles is again attained. In order to adjust the extension of the bristles, the brush 60 is reversed end for end to the position shown in Figure 6 and the lugs 63' and 64 respectively abut the seats 65 and 65, whichresults in the bristles 62 being extended a length equal to the height of the lugs 63 and 54.
If it is desired to disconnect the swivel joint, the brush 69 is removed by unthreading the screw 68 and thereafter the locking member H is slidably removed from the grove 16 and holes 1515. Inassembling the swivel joint, the lockng mem ber is inserted in the holes ll5 into the groove 16 and is held in operative position by attaching the brush 60 in the housing I9.
