s oi (oi. is-ei My invention relates to' suction cleaners and has for an object to provide improved apparatus of this kind.
A further object of the invention is to provide improved means for adjusting the rotating brush of a cleaner for floor coverings.
A further object of the invention is to provide improved suction cleaning apparatus having a rotatable element that engages the surface being.
- cleaned wherein the element may be readily ad- Justed relative its support without removing the element from the cleaning apparatus.
A still further object of the invention is to pro-'- vide an improved adjustable rotating brush structure for a suction cleaner having indicla for indicating the position to which the brush is ad- Ihese and other objects are effected by my invention as will be apparent from the following description and claims taken in connection with the accompanying drawing forming a part of this application. in which: 7
Fig. 1 is a sectional view through a portion of a suction cleaner nozzle having a rotatable brush structure therein constructed and arranged in accordance with the invention;
Fig. 2 is a section taken along the line 11-11 of Fig. 1; and,
Figs. 3 and 4 are side and end views respectively of the bearing member shown in Fig. 1.
Reference will now be had to the drawing wherein I have shown a portion of a conventional suction cleaner nozzle at "having a rotatable brush ii disposed therein and actuated in any well-known manner such as, for example, by the suction creating apparatus (not shown). The opposite end of the nomle IO and brush ii are not shown as-the construction thereof is similar to the end shown. The male ill is provided at its bottom with lips' I! that engage the floor covering to be cleaned and which encompass an inlet opening I! for air translated through the nozzle. The brush ll includes a plurality of bristles. N that normally extend slightly below the plane of 5 the lips i2 and sweep the surface being cleaned sary to the brush structure it downwardly in order to obtain proper contact between the bristles i4 and. the iioor covering. 'Ihe adjustment of the brush upwardly and downwardly is eifected by the adjustable bearing structure II to g be described hereinafter. when the brush it is new, the bearing structure is adjusted to its most elevated position and. as the brush becomes worn. the bearing structure isperiodically adjusted to lower the brush H. structure includes abearingmember il. preferably polygonal in cross section as best shown in Figs. 2 and 4 where it is supported from the nozzle ll. Inthe embodiment shown.thebearing member is hexagonal in cross-section for providing six i'aces it on the exterior thereoi. the faces il being spaced uniformly from the centerof the bearing member ll andthebrushiournal lIbeing eccentrically disposed with respect to the center ofthebearingmemberlhasbestshowninmd.
Support tor the bearing member i1 is provided withinthe nozzle II by means or a pair of flatsprings i! that are secured to the nozzle II by means or ascrewil. The springs ll bearagainst opposed sidealiof thebearing member I! and are a preferably provided with inwardly extending portions 22 which prevent downward movement of ,the bearing ii in service. Upward movement of the bearing i1 is prevented by the screw 2 I.
Adjustment of the brush ll upwardly and go downwardly is eflected by rotating the bearing member i'l within its resilient support. As the center of the bearing member I1 is maintained in a fixed position relative the nozzle II, it will be apparent that the Journal ll whichis eccentrically 5 disposed with respect to the center of the bearing member It, will be raised or lowered depending upon which direction the bearing member I1 is rotated. In the position shown, the bearing member i1 is adjusted so that the journal I! of the brush is in its most elevated position, or the position occupied when the brush is new. Rotation of the bearing member I! clockwise to bring the next succeeding faces it into engagement with the springs I! will efiect a downward move- 5 meat of the brush ii, which operation is eifected when the brush has been worn suflici'ently to require adjustment. It will be apparent that the hexagonal bearing member I! provides for four positions of the brush ll.
In order to facilitate rotation of the bearing member IT, a plurality of recesses or slots 23' are formed on the exterior thereof for receiving a suitable tool such as, ior example, a screw driver, which may be inserted through the inlet gg The adjustable bearing 1 opening iii of the nozzle Ill. After inserting the tool in a recess 23, it is moved to eifect a rotary movement of the bearing member II, at which time the springs I9 flex to permit the corners intermediate the faces It to pass. The springs l9 then move inwardly to engage the next succeeding pair of faces ll. Indicia indicated at 2, such as, for example, the numerals I to I, may be provided on the outer surface of the bearing member l! for indicating the position to which it has been adjusted. In this connection, it will be understood that the bearings at both ends of the brush II should be adjusted to the same index. The resilient springs Is for supporting the bearing member I! readily permit insertion and removal of the brush and bearing H from the nozzle l0 when desired.
From the foregoing description, it will be apparent that I have provided improved means for adjusting the rotatable brush of a cleaner for floor coverings that may be readily adjusted without removal of the brush from the apparatus. Furthermore, the brush may be readily removed from the apparatus if desired, for cleaning or replacement.
While I have shown my invention in but one *form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposedby the prior art or as are specifically set forth in the appended claims.
