INVENTOR TTORNEY Patented Dec. 31, i946 UNITED STATES PATENT OFFICE CARPET SWEEPER Irving Richardson, Newark, N. J. Application February 2, 1939, Serial No. 254,229
7 Qlairns.
This invention relates to improvements in carpet sweepers.
An object of my invention is to provide a novel means for mounting the brush within the sweeper in a manner which will enable the brush to be easily removed and inserted for cleaning the same or for any other purpose.
A further object of my invention is to provide the sweeper with a member for rotatably supporting one of the brush pulleys in a manner which will enable the brush to be readily tilted for removal or insertion, and a second member adapted to rotatably and selectively engage or disengage theother brush pulley.
A further object of my invention is to provide supporting means for the brush pulley adjacent the second member.
In the accompanying drawing, in which is shown some of the various possible embodiments of the several features of the invention, and wherein like reference numerals indicate like parts: i
Fig. 1 is a bottom plan view of a carpet sweeper embodying my invention,
Fig. 2 is a perspective, enlarged View, partly broken, of the member for tiltably supporting the brush, shown in normal position,
Fig. 3 is a fragmentary, enlarged, perspective View, taken on line 33 of Fig. 1, showing the second member in normal position, but shown disengaged from the brush pulley,
Fig. 4 is a perspective View of the spring finger and stub shaft of the second member, shown in Fig. 3, and
. Fig. 5 is a vertical transverse sectional view taken on line 55 of Fig. 1, showing the brush in tilted position, the spring finger being shown in its disengaging position.
As shown in the drawing, the carpet sweeper of my invention comprises a casing I having side walls 2-2 and end walls 3, to which a bumper 4 is preferably secured in any desired or convenient manner. The casing is provided with bearings 5 for traction wheels 6, the latter having frictional driving engagement with the pulleys 1--l of the brush 8, in any of the various arrangementst well known to those versed in this art, rotating the brush 8 between the dust pans 9.
A member I0 is secured to the side wall 2 of the sweeper by rivets II or in any other convenient manner. The member it comprises a pair of arms 12 preferably integrally connected in spaced relation, each arm being provided with an aperture l3 defined by oppositely arranged vertical edges M and angularly directed edges It. A plate It is tiltably carried by the member"). In the form of my invention shown in the drawing, the plate is provided with oppositely disposed, shouldered protuberances l1 operable in the apertures l3 of member IE]. The plate It is provided with a stub shaft 58 adapted to support the brush pulley l as shown in Figs. 1 and 5. A second member id is secured to the side wall 2 and is adapted to selectively engage (as in Fig. l.) or disengage (as in Fig. 5) the other brush pulley l. The second member I9 is shown to comprise a spring finger 26 one end 2i of which is secured, by rivets 22 or the like, to the side wall 2 of the sweeper; the spring finger is provided with a stub shaft 23 adapted to support the brush pulley l as in Fig. l. The side wall 2 is provided with an angularly directed portion 24 within which the spring finger 2% is adapted to operate, the free end 25 of the spring finger protruding through the opening 26 of the portion 24 to serve as a thumbpiece for contracting the finger as in Fig. 5; the stub shaft 23 is adapted to reciprocate in the aperture 21 of the front wall 29 of portion 24. The front wall 29 of portion 24 is provided with the arcuate ledge 28 on which the pulley I is adapted to rest when, on contracting the sprin finger 20, stub shaft 23 is withdrawn from the pulley I. By grasping pulley 1', the brush 8 may be tilted on the plate l6 as in Fig. 5 and readily drawn off the stub shaft [8. To replace the brush 8 it is merely necessary to reverse the operation. It will be noted that when the brush is positioned in the sweeper as in Fig. 1, the protuberances I! abut the vertical edges M of the apertures I3, and when the brush 8 is tilted as in Fig. 5, the protuberances 11 have limited movement in the apertures, between the edges l4 and I5 thereof. This arrangement assures the horizontal alignment of the brush when in its normal position, as in Fig. 1, and provides for the easy, controlled removal and insertion of the brush.
It will be noted that the construction described enables the pulleys of brush 8, when supported on stub shafts l8 and 23 as in Fig. 1, to snugly abut 0 the plate l6 and the front wall 29 of portion 24, assuring smooth operation of the brush; if desired, the pulleys may have roller bearing rings 39 as shown in Fig. 5.
The bail 29 may be secured to the sweeper in any desired or convenient manner; preferably, one end of the bail passes through the spring finger 20 adjacent the riveted end 2| thereof to further displaceably secure the finger 20 to the side wall 2.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a carpet sweeper having a side wall and having a carpet sweeper brush provided with pulleys at opposite ends, a fiat plate, a member secured to said side wall, said plate and member being provided with complementary means for tiltably journ-aling the plate in said member to enable the plate to be tilted in a plane transverse to the plane of the side wall, a stub sha'ft secured to said plate rotatably and disengageably supporting a pulley of said brush, said pulley abutting said plate when supported thereby and means secured to the carpet sweeper to rotatably support the other pulley.
