The rotary brush A, is placed in a wooden box or casing B, by which it is
enclosed on all sides with the exception of the bottom, and is held in position
by and rotates on pins or pivots C which fit loosely into sockets formed one at
each end.
The pin or pivot C, at each end, is carried by a metallic strap D which is
attached to the end of the box or casing B; these straps and supporting pivots
being so placed that the brush projects beyond the bottom edges of the box. The
apparatus is supported by wheels or runners E, two at each end of the box B—
the two at one end also serving to rotate the brush A, and it is provided with two
pivoted trays F, into which the dust is deposited as it is swept or brushed up from the
floor.
A handle is attached to the box, preferably by means of a pivoted cross-rail G and
socket, into which it is screwed. The cross rail G, is pivoted at g in each end of the
box or casing B.
The wheels E, run loose on the ends of the spindles or studs H-preferably
spindles running across from end to end, and which are held in position longi-
tudinally and upon which the wheels are maintained in position, by washers over
which the ends are riveted; the metallic straps D which carry the brush passing
round their ends.
The spindles H, are supported at each end by a wire spring I or J, of approximate
V-shape, one end of which clips round the end of the spindle and the other is inserted
in or attached to the inside of the box or case B. These springs are so set that when
the apparatus is laid lightly upon the floor the brush A is set so as to touch the
carpet. Any pressure applied to the box forces the springs up and it and the brush
down, the brush being raised when the pressure is relieved. In use we find the
tendency is for the back part of the apparatus, over the back pair of wheels, to be
depressed more than the front part, over the front pair, and to obviate this we mount
the back axle H on springs I considerably thicker or stronger than the springs J,
upon which the front wheels are mounted, and by this means we obtain an even
depression of the box. The springs I and J which support the axle may be placed
in a convenient position either inside or outside the box and may be made of any
desired shape or form.
The trays F into which the dust is deposited from the brush A, are pivoted at f
and and attached to one end of each is a sliding wire spring L. By raising the
outwardly projecting centre loop 7, of the sliding spring L, the lower inner edge of
each tray is drawn up, and the outer edge falls to empty the dust collected thereon.

page_text: The sliding spring L, acts as a spring to hold the trays up and closed when the
sweeper is in use.
M, is an indiarubber buffer, in the form of an endless band, which is placed round
the case B, to prevent the apparatus damaging furniture on being knocked
against it.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
An apparatus for sweeping or removing dust from the surface of carpets having the
springs that support the wheel spindles constructed with the back pair of springs
stronger than the front pair, to equalize the depression of the back and front of the
apparatus, substantially as described.
