INVENTOR.
JOHN A. KEMPER ATTORNEYS United States Patent John A. Kemper, Cleveland, Ohio, assignor to The Scott & Fetzer Company, Cleveland, Ohio, :1 corporation of Ohio Application December 1 6, 1957, Serial No. 703,046
8 Claims. (Cl. 15371) This invention relates to a suction cleaning tool, and particularly to a suction cleaning tool wherein a brush is adjustably positioned with respect to the working face of the tool and in the suction path. This invention is particularly applicable to suction nozzles commonly utilized in connection with vacuum cleaners.
Much work has been done to develop a satisfactory arrangement for the mounting of a brush in a suction nozzle. The mounting of the brush has generally been accomplished by fastening means, such as bolts, screws, etc., which have been either threaded into thenozzle or caused to pass through it.
Complications arise when the brush is to be located directly in the suction passage of the nozzle rather than located at the back edge of the nozzle and outside of the direct path of the suction. Further, difficulties are encountered when the nozzle is made of a plastic or rubberlike material since these materials generally do not have suflicient holding ability for threaded fasteners and the. drilling of holes in the plastic or rubber materials causes. weakening of the structure. Also, some of the brush mounting arrangements proposed have been satisfactory from a mechanical or operating standpoint but have resulted in the nozzles being objectionable from an appearance standpoint. v
In accordance with the present invention, the difiiculties mentioned above are overcome, and an improved brush mounting arrangement is provided for a cleaning tool by which the brush is disposed intermediate the suction opening. Also, a resilient mounting for the brush is provided which can be adjusted so that the desired amount of projection of the brush with respect to the working face of the tool is readily obtainable. In addition, the invention provides an improved brush mounting arrange ment which can be incorporated in a suction nozzle without drilling or machining holes or cavities in the suction nozzle. Further, an improved brush mounting is provided which does not weaken the nozzle and is simple in its construction and easy and low in cost tomanufacture.
The present invention also provides a cleaning tool which has an aesthetically acceptable appearance and which is characterized by the simplicity of its components and the ease of manufacture and assembly thereof.
The specific nature of the present invention, as well as other advantages thereof, will become apparentto those skilled in the art from the following detailed description and the drawing, in which:
Figure 1 is a bottom view of the cleaning tool embodying the present invention.
Figure 2 is an enlarged sectional view, taken along line 2-2 of Figure 1, illustrating the particular brush mounting arrangement of the present invention.
Figure 3 is a further enlarged view of the mounting arrangement taken along line 3-3 of Figure 2.

Figure 5 is an enlarged front elevation of the spring clip.
- tion opening of the nozzle.
2,932,055 Patented Aer. 12 1950 ice As herein shown, a suction cleaning tool comprises an air conduit 10 and a suction nozzle 11, having end portions 12 and 13 and longitudinal side portions 14 and 15 which define an elongated suction opening 16 and a sue tion passage to connect with air conduit 10, which in turn is connected to a suction source.
Extending'transversely from the walls of the suction passage are pairs of cooperating ribs 17, 18, 33, and 34. These ribs are positioned in opposing relationship on the sides of the nozzle between the central air conduit and the ends of the suction opening of the nozzle. Preferably, the pairs of cooperating ribs are'so positioned that, as described hereinafter, brush mounting brackets can be located near the ends of the brush.
The distance between the pairs of ribs 17 and 18 is such that arcuate spring clips 19 and 20 positioned be tween the respective pairs of ribs 17 and 18 are held in position by frictional contact against the sides of ribs 17 and 18. The spring clips 19 and 20 have pairs of ear portions 21 and 22 which frictionally engage the sides of the ribs 17 and 18. To aid in the frictional engagement, the ear portions 21 and 22 have struckup centers 37 which resiliently press against the sides of the ribs.
The spring clips 1% and 20 overlap each other at the top of the suction passage. In the zone of overlapping, the spring clips 21 and 22 have apertures which engage stud 23 depending from the top portion of the nozzle. The stud 23 and the ribs 17 and 18 cooperate to maintain the spring clips 19 and 20 in operative position.
A strip brush 25 is provided for mounting in the suc The strip brush comprises bristles secured around a suitable wire and held in position by means of a channel-shaped, elongated holding member. To the elongated channel-shaped holding'member of the strip brush are aflixed supporting brackets24' and 32. This brush assembly is secured to the spring clips;
19, 20 by bolts 26, 27 through threaded apertures 28, 29 of the quick fastener type in the spring clips 19 and 20.
One end of a suitable spring, such as helical spring 30, is positioned over the stud 23 depending from the top of; the suction nozzle and the other end over a stud 31 extending from the top of the supporting bracket 24 of the brush assembly. The helical spring 30 maintains an outward thrust against the brush assembly to hold the brush member 25 in an outwardly extending position with re-- spect to the suction nozzle.
In a similar manner, supporting bracket 32 is fastened" spring (not shown).
According to the present invention, the brush member is resiliently mounted in such a manner that it is permitted to move bodily in its plane and parallel to the side walls of the nozzle. As stated above, the springs maintain the brush member in an outwardly extending position and the extent of movement of the brush assembly is con trolled by the bolts 26, 27, 35 and 36. The extent of projection of the brush assembly may be increased or decreased by positioning these bolts in the threaded apertures of the spring clips. As the brush member becomes Worn through use, adjustment of the bolts may be made to obtain the desired amount of projection of the brush member.
When the brush member becomes so worn that it must be replaced, replacement may beeasily accomplished by disengaging the bolts 26, 27, 35 and 36, removing the old brush assembly, inserting a new brush assemblyv and refengagingthe bolts.
The suction cleaning tool body comprising air conduit especially applicable to nozzles made of a plastic or rub ber-like material, it may also be useful with nozzles made.
'from a light metal, such as an aluminum alloy, etc.
As stated above, the present invention provides an improved brush mounting arrangement for a suction cleaning tool which is of simple construction and can be easily manufactured and assembled at low cost. Furthermore, the present invention provides an arrangement for mounting a brush without drilling or machining holes into the nozzle.
Also, the present invention provides a brush mounting arrangement which permits the brush to be mounted intermediate of the suction opening and in thedirect path of the suction. This construction causes the dirt agitated by the brush to be sucked into the vacuum cleaner irrespective of the direction in which the suction nozzle is moving during the cleaning operation. As a result, the suction tool of the present invention operates more efficiently and with less effort on the part of the user compared with conventional suction tools having the brush located at the back part of the nozzle and outside of the direct suction path.
Although the invention has been illustrated and described with regard to the preferred embodiment of the invention, it will be apparent to one skilled in the art that various modifications may be made and such modifications are intended to be within the scope of the invention as set forth in the following claims.
