VACUUM CLEANER BRUSH OriginalFiled Sept. 30. 1927 INVENTOR,

norm use, or naooxnim, NEW YORK vacuun-ctnam nnusn Original application flea Septcnibcr 80, 1827, Serial No. 228,062. Divided and this application fled. larch 81, 1928. Scria11i'o.268,812.
M invention relates particularly to brus es for vacuum cleaners, useful for cleaning clothes, furniture, draperies, etc.
One object of invention is to prevent the cloggm of the brush with threads, etc.
Another 0 ject is to facilitate the cleaning of the brush.
Another object is to facilitate replacement and repair of the brush.
In carrying out my invention, I suspend the brush and its drivin belt in a chamber in the bottom of a casing which chamber' is entirely open for the entry of this brush. This chamber is closed by a removable bottom plate, having a suction inlet facin the brush;
This brush is made of a sha having a pulle and longitudinal fins or plates along the sliaft and bristles set either on the fins or extending from the shaft.
This brush can also be made of two sha sections havin longitudinal fins or plates along the sha s and means for attaching these sections with the pulley.
Fig. 1 is an edge view and partial longitudinal section of the parts involving my mvention showing the bottom late in place.
Fig. 2 is a view showing t e-underside of the device with the bottom plate in place.
Fig. 3 is a side view of the brush. Fig. 4 is an end view of the brush. Fig. 5 is a detail view of parts of the brush and 1ts driving pulle s I Fig. 6 is an end view of a modified form of brush. I The @casing 10 is adapted to contain any suitable form of motor and suction fan. The lower part 11 of the casing may be secured to the upper part by a series of screws 12. A switch (not shown) having an operating lever 13 may be provided for turning the motor on and off.
The bottom of the casing is provided with a chamber 14 which extends outwardly at one end and is normally closed when in use by a plate or cover 15 having-one or more suction openings 16 facing the brush. The dirt, etc., is picked up by the brush and-drawn through the opening 16 and passes through the casing and is ejected through the tube 17 for instance by means of ,a hinge 21 at one is provided with a pulley 28 which is conand'collected or'disposed of in any suitable manner. v.
The joint between the late 15 and the bottom of the casing may e made air tight in any suitable manner, as for instance by '55 .providing a rubber gasket 18 and/or a flange 19 on the cover which overlaps the edge of the casing inside the recess 14. This plate 15' may be secured in any suitable manner, as
to end and a spring catch 22'at the other end.
The brush may consistof two shaft sections 23 connected by a ulle 24 into which. they are screwed. The rus ends are supported in suitable bearings in the opposite sides of the chamber 14 in the casing in any suitable manner. k
The drive shaft 27 of the fan motor extends into one end of the chamber 14 and nected by means of a uarter turn belt 29 to the pulley 24 of the rush. In such devices in the past it has been customary to use an elastic belt which rapidly deteriorates due to the heating to "which the device is frequently subjected. I refer to use a leather belt or a belt of other urable material which need be only slightly yielding so as to permit stretching suflicient to allow one end of the shaft 23 to be tilted up for the purpose of so removal and replacement. e
In order to prevent threads, hair and the like from becoming entangled with the bristles 30 of the brush, I provided lates, or fins 31 which extend outwardl ii'om the I shaft 23 and tend to knock oif s Ort threads and the like and prevent them from remaining in. the brush. i
I prefer to provide these fins spaced apart from each other so that if lon threads, or the like, are wound around the fins they will be held spaced apart from the shaft" so that a knife or the blade of a pair of scissors can be readily inserted between the fins to cut the thread and facilitate its removal. The bristles 30 may be mounted directly in the fi-ns or plates 31' as shown in Fig. 6.
To replace a part of the brush a section of the shaft 23 is detached from the pulley 24 and a new section can instead beattached 199 I claim: A brush for a vacuum cleaner comprisin a shaft, a number of rows of bristles secured to said shaft and radially disposed there;
around, and a plurality of radially extending" longitudinal fins interposed between rows 0 bristles and spaced from each other circumferentially of the brush.
