l12 Claims.
'Ihis invention relates to suction sweepers and in particular to the brush drive and brush mounting of a device of the type described.
One of the objects of this invention relates to the provision of an improved form of driving belt pulley for the brush drive of a suction sweeper which pulley is adapted to maintain the belt at all times in its operative position on its pulleys.
A further object of the invention relates to a quickly detachable suction sweeper brush mounting of simple and inexpensive construction having provisions for maintaining the brush bearings in proper alignment; for readily effecting the adjustment of the brush with respect to the worklng mouth of the sweeper; for reducing the transmission of noise from the brush to the cleaner casing; -for facilitating the removal of the brush 'from the cleaner nozzle; and for readily disassembling the brush bearings for cleaning and With these and other objects in view, the invention consists in Athe novel construction, arrangement/and combination of parts, hereinor after illustrated andv described in some of its 0 embodiments in the accompanying drawing, and particularly pointed out in the appended claims. y In the drawing, Figure 1 is a side elevational viewgfpartly in section, of an electrically operated suction cleaner with certain of the parts 'f-ftne'cleaner shown in section to better inusft'rate: the details of this invention; Figure 2 is a detailsectional view taken on line 2 2, Figure 1; and Figure 3 is an enlarged detail sectional view itaken on line 3--3, Figure 2. The suction sweeper illustrated in the drawing.' comprises a casing structure including a motor housing I, a fan case 2 and a suction nozzle 3l arranged one in front of the other in the Y order named. An electric motor located withinl the motor housing i has its armature shaft 4 extended into the nozzle 3, and at a point adjacent to the outer end of the shaft itis reduced in section to form a pulley 5 for a brush driving belt 6. In forming the pulley 5, an annular flange 'I is left on the end ofthe shaft to prevent the belt from crawling or sliding o of the pulley 5. Casters 8 are provided for supporting the sweeper ncasing. The nozzle 3 is provided with an opening 9 by Way of which access may be had to the belt and the belt driving pulley. A removable cover I0 is provided for the nozzle opening 9. The lowermost part of the nozzle 3 is provided with lips I i defining the suction or working mouth of the cleaner. A brush I2 is rotatably supported in PATENT ol-FICE the nozzle of the sweeper immediately above the working mouth thereof and it is provided with a pulley face intermediate its ends below the motor armature shaft 4 and the pulley 5 formed on the end thereof- The cover I0 is provided with spring clips 9, 9a .by means of which it is held in place over the nozzle opening 9. The cover I0 s also provided with an offset lip 9b adapted to be engaged by the finger of the user for facilitating the removal of the cover. 10
Due to the provision of the flanged end 1 on the pulley 5, it is possible to locate the pulley of the brush I2 with its axis a substantial distance ahead of the-center of the driving pulley 5 instead of directly below the same as is the customary arrangement. This permits the 1ocating of the working mouth of the cleaner a greater distance forwardly of the cleaner than has heretofore been considered possible or feasible to do, and by reason of the arrangement of 20 the parts just described, the front face of the cleaner nozzle may be sloped backwardly a considerableamount to the enhancement of the appearance of the cleaner casing.
The detachable brush mounting and the details 25 of the brush bearing are illustrated best in Figure 3 of the drawing. At each of the ends of the nozzle 3, there is provided an inwardly extending boss I3 adapted for the adjustable reception of a threaded brush supporting post or pin III, hav- 30 ing a ange I5 intermediate its ends and a slotted head I6 at its outer end. A sleeve I'I formed from a, yielding elastic material, as for example -soft rubber, is carried on the unthreaded'portion of the post member I4. ,35
The brush I2 is formed with an axial bore I8 extending they length of. the brush for reception of a rod 20. The ends of the rod are each received in identical brush supporting members 2|. The inner parts 22 of these members 40 engage with the inner races of anti-friction bearings 23. The outenrace of each of the bearings 23 is snugly received within a cylindrical sleeve 24 and the inner end of which is formed at its edge with a shoulder for receiving a cap 25 hav- 45 ing a central aperture for reception of the rod 20.
f A lubricant retaining, dust excluding washer 26 is carried in an annular space defined by the brush supporting member' 2|, vthe bearing 23 and 5" the cylindrical sleeve 24.' The outermost end 2l of the brush's'ilpporting member 2i vis in the form of a U-shaped extension which Vembraces and engages the rubber sleeve il when the brush is in its operative position, the brush being held in placev by reason of the frictional engagement of the parts just described, and in this connection,
. the belt 6 also tends to maintain the brush in proper position.
are frictionalI/y ntted into the ends of the brushl and their replacement, when necessary, may be y readily eiected'. y i
The foregoing details of construction illustrating a preferred form of the invention, disclose a simple form of adjustable brush mounting hav-VA ing provisions for the easy and ready removal of thebrush, with means to 'maintain the brush bearings in proper alignment, including means for insuring proper lubrication of the brush bearings whiie at the same time excluding dust and dirt'therefrom, and means for permitting the inspection, cleaning and lubricating of the brushV bearings as well as. means for permitting their ,ready removal and replacement if necessary.-
Furthermore, it is to be understood that\the particular .forms o! suction sweeper shown and described, and the particular procedure set forth are presented for purposes of illustration ,and explanation and that various modifications. of said apparatus and procedure may be made with out departure from the invention 'as dened in the appended claims.
