Improvements in Carpet Sweepers.
I, HAROLD SIMS JOSEPH BOOTH of Nos. 6 and 7 Cross Lane, Eastcheap in
the City of London, Merchant, do hereby declare the nature of this invention to be
as follows :-
-
This invention relates to the known apparatus employed for sweeping carpets,
consisting of a car which is pushed or drawn along the carpet, while a revolving
brush driven from the car wheels delivers the dust and other matters swept from
the carpet into lateral trays. The present invention relates to means of moving
these trays down so as to discharge the dust and other matters from them and
moving them up again into position for receiving sweepings. For this purpose,
from a point of each tray nearer the middle of the apparatus than the point on
which the tray is pivotted a wire is led up in an inwardly inclined direction to. a
position above the bearing of the revolving brush, where the two wires meet in a
crosshead to which they are jointed. Or the two wires may be in one piece bent
to form two limbs extending down to the trays and turned into hook form where
the bend occurs. The crosshead or hook is raised and lowered by a rod with a
knob or button presenting itself at the top of the sweeper, this rod being screw
threaded or preferably made with a bayonet catch so that by giving it a partial
turn the parts are held in the position to which they are moved or the hook
may be engaged in a cam slot on one arm of a lever, the other arm of which
presents itself at the top of the sweeper, or it may be engaged with a crank on a
spindle that passes through the side of the sweeper and has a knob or handle
outside for turning it.

Improvements in Carpet Sweepers.
I, HAROLD SIMS JOSEPH BOOTH, of Nos. 6 and 7 Cross Lane, Eastcheap, in
the City of London, Merchant, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention relates to the known apparatus employed for sweeping carpets,
consisting of a car which is pushed or drawn along the carpet, while a revolving
brush driven from the car wheels delivers the dust and other matters swept from
the carpet into lateral trays. The present invention relates to means of moving
these trays down so as to discharge the dust and other matters from them and
moving them up again into position for receiving sweepings as I shall describe
referring to the accompany drawings.
Fig. 1 is a transverse section near the one end of a carpet sweeper shewing one
arrangement according to my invention for raising the trays to discharge the dust ;
Figs. 2 and 3 shew modified arrangements.
In all figures like letters denote corresponding parts, namely
C the casing, W the wheels that run on the carpet, A the axle of the brush B,
H the handle by which the sweeper is lifted and pushed along the floor, TT the

page_text: dust trays which are pivotted at t t. From points pp near the inner edges of
the trays TTI lead wires D D in an inwardly inclined direction, as shewn in
Fig. 1 and joint them to a crosshead E above the axle A. This crosshead is
swivelled on a rod R which is lead up through a tube G and through the top
of the casing and terminates in a button or handle K. The rod R has a pro-
jecting pin which on turning the rod partly round and drawing it up can pass
up a slot of the tube, the trays T being thus canted to an inclined position as
indicated by the dotted lines, so as to discharge the dust from them. On
pushing down the rod R the trays are raised to their level position in which
they are held by partly turning the rod R so that its pin r is under a shoulder
at the side of the slot in the tube G.
As shewn in Fig. 2 a single wire D is bent into V form each limb of the V
being jointed to one of the trays T. At S the angle of the V the wire is
bent back to form a hook which is engaged in the cam slot of a lever L pivotted
at . By moving the lever over in either direction the wire D is raised canting
the trays T T. Instead of forming the lever L with a duplicate cam slot, it
might have a single such slot, the lever lying over to the one side when the
trays are level, and being moved over to the other side for cauting the trays.
As shewn in Fig. 3 a spindle F passes through the side of the casing having
an external button or handle F1 by which it can be turned, and internally a
crank which takes hold of the bent wire D connected to the trays TT so
that by turning the spindle F the trays are canted to the position shewn by
the dotted lines.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In a carpet sweeper, in combination with the dust trays a pair of wires or a
wire jointed to thein and connected to a sliding pin or to a slotted lever or
crauk, substantially as and for the purpose set forth.
