6 Claims.
Among the objects of the invention are to provide a simple, inexpensive, compact, reliable, durable and Well balanced device of small size which can be readily manufactured, inspected, cleaned and repaired.
Special objects are to provide a construction which will avoid so far as possible clogging of the brush and bearing or damage to the belt and `to facilitate removal and replacement of the brush and cleaning of the brush and belt chamber.
The drawing illustrates the preferred form of the invention.
Fig. 1 is a side and vertical longitudinal sectional view illustrating the invention.
Fig. 2 is a vertical transverse sectional view showing the brush and its supports.
Fig. 3 is a transverse sectional view of the brush.
Fig. 4 is a longitudinal sectional view showing parts of a brush and its bearings.
Fig. 5 is an inside view of a fragment of the bottom plate.
The casing is made up of two parts, the lower or body member casting containing the brush land suction fan and the upper hood member 11 containing the' motor 12 with its usual brushes and switch 13. These two parts have appropriate chambers for the motor and fan and are held together by a number of -screws 15. The suction fan and motor and associated parts are described and claimed in myrcompanion application aforesaid.
The suction fan or blower 14 is mounted on the lower end of the motor shaft 16 being held in place by the pulley 17 which is screwed on to the bottom of the shaft.
The bottom of the body of the casing is provided with a chamber 18 which contains the driving pulley 17, the brush 19 and the-quarter turn belt 2l) which connects the pulley 17 and the pulley 21 in the center of the brush structure.
The brush is so constructed that it can be inserted and removed as a unit to facilitate cleaning and replacement.
' The belt 20 is preferably formed of elastic rubber. l
The shaft or spindle 22 of the brush is preferably tubular and provided with anti-friction or Vself lubricating bearings 23 supported in metal yhousings 24. These bearings and housings are removably mounted on the ends of the shaft 22 and held in place by the plug members 25 which lit snugly in the ends of the shaft.
The brush consists of two sections, one on each side of the pulley 21.
Each end of the brush shaft is preferablyprovided with a guard washer 26, the flange of which ares outwardly over the rim of the housing 24 so as to prevent threads, dust andv lint from getting into the bearings.
The brush is also preferably provided with fins or plates 27 arranged between the brush tufts so as to prevent threads from being wound up on the shaft but cause them to be held spaced apart from the shaft in such a way that it will be reasy to insert the point of a pair of shears for the purpose of cutting the threads to facilitate removing the same. These fins may be suitably formed, for instance, by stamping them out of sheet metal into channel-like shape and riveting or otherwise securing sections to the shaft 22 between the pulley and the end washers 26. Preferably these fins are concave along their edges and of less radial extent in the center of each brush section than vat the ends of the brush sections. 'I'he result is that the threads tending to collect on the fins are naturally drawn toward the center of the brush section where they can be more easlly cut and removed.
The opposite sides of the chamber 18 are pro- 85 vided with openv ended bearing sockets, 30, into which thehubs of the housings 24 are adapted to be inserted and secured, Spring abutments 31 are preferably provided to engage the hubs of the brush bearings and thus yieldingly press the brush outwardly.
It will be noted that the entire bottom of the suction chamber 18 is open so as to facilitate inspection of the brush and belt and removal for cleaning and replacement. A bottom plate 32 is 95 hinged to the casing at 33 and provided with a flange 34 which fits within the edge of the chamber 18. The relatively narrow part 35 of this bottom plate is off-set or projects downwardly from the remainder of the bottom plate so as to 100 provide a narrow bearing or foot provided with two openings or mouths 36-36 separated by a bridge 37 which covers the belt 20.
'This bridge is preferably provided with flanges 38 which overlap the edges of the pulley 21 so as to protect the belt and the pulley from thread, dirt, etc. 'Iheends of the plate 35 are also preferably provided with flanges 39 to 'guard the edges of the bearing washers 26 and prevent 110 thread and dirt from clogging up the ends of the brush and the bearings.
The bottom plate 32 has lugs or abutments 40 on opposite sides adapted to press against the hubs of the bearing members 24 to hold them in place against the yielding pressure of the springs 31.
A yielding steel or other durable latch 41 is secured to the bottom plate inside the casing where it engages the spring pressed plunger 42 to yieldingly hold the bottom plate in place against the pressure of the springs 31. The bottom plate 32 is extended to form a finger-piece 43 to facilitate opening the casing for inspection, repair, etc.
The bottom plate is thus constructed so as t0 prevent any part of the brush structure (except the bristles) from coming in contact with the fabric or article being cleaned.
It is to be understood that the device may have a handle portion 44 with an extension 45 of any suitable sort and provided with a suitable dust collecting receptacle as usual if desired. The apparatus can also be used for blowing purposes and for fumigating or deodorizing without a dust-bag, in which event the brush may also be removed or a fumigator may be employed together with the dust removing brush and a collecting bag.
I claim:
1. A vacuum cleaner having a brush with 1ongitudinal ilns between the bristles, said fins having less radii near the center than at the ends of the ns so as to cause threads to accumulate away from the ends of the ns.

3. A vacuum cleaner brush having a shaft with longitudinal radially projecting fins between the bristles and a guard washer on at least one end, the said fins having greatest radii adjacent the washer and tapering to lesser radii away from the washer, the washer having a conically inclined flange flaring outwardly from the ends of the fins so as to cause threads to slide from the flange and accumulate on the fins away from the washer.
4. A vacuum cleaner brush having a shaft with a pulley and longitudinal flns projecting radially from the shaft between the bristles, said ns being of greatest radii near the pulley and having edges tapering to lesser radii away from the pulley to cause threads to slide along the ns and accumulate away from the pulley.
5. A vacuum cleaner brush comprising a spindle, anti-friction bearings on the opposite ends of the spindle, a housing for each bearing adapted to be detachably seated in a recess in the side wall of a vacuum cleaner casing, said housing having a flange atits inner end extending transversely of the axis of the spindle and a guard washer secured on the spindle near each end having an inclined flange flaring outwardly over the periphery of the flange on the adjacent housing to direct threads from the bearings and means for securing each bearing and its housing on the spindle.
6. A vacuum cleaner brush comprising a spindle having bristles, an anti-friction bearing Aheld on each end of the spindle and having a housing with a peripheral flange, and a cup-like guard flange having an outwardly flaring edge portion carried by the spindle forming a pocket for the flange on the housing and deilecting threads from the bearing.
