BYRON HENRY EVERS of 79 Mark Lane, London in the County of Middlesex,
Merchant do hereby declare the nature of this invention to be as follows:-
This Invention has reference to further improvements in "Carpet Sweepers" to
those for which Letters Patent of Great Britain were granted to me bearing date
November 12th 1884, and numbered 14,907.
The object of my invention is to make a "Carpet Sweeper" that is self-regulating,
in order to over come the objection of adjusting the brush by thumb-nuts and set-
screws whenever required in its operation of sweeping from a thin to a thick
carpet and vice-versa, and is accomplished by the using of a Bail or Forked-like
attachment to which the handle for propelling the sweeper is affixed in the ordinary
way by being screwed on a screw cast or otherwise formed in the center of said bail.
The said bail having at each of its extreme ends a spur projecting inwardly and then
upwardly which fit into an opening or receptacle formed in the end castings and acts
as a lever indirectly upon the projecting portion of springs secured to the under
surface of the flat central portion of the cover at opposite ends. Upon the outer or
projecting portion of springs is rivited or otherwise secured a shaped piece of metal
acting as a fulcrum to lower spur of bail and to which are secured by means of
set-screws Brackets having bearings for axle of brush-roll, said brackets having slots
to allow the brush being lowered (this only being necessary after long use, when the
brush becomes somewhat worn) if required.
Near the extreme ends of bail is a further spur projecting inwardly but only
extending to the surface of the end-castings which act in unison with a groove (formed
in the under surface of an offset cast on and forming part of end-castings) to keep the
bail with handle in an upright position and self-supporting when not in use, said
upper spur being forced into the groove by the pressure of the springs upon the lower
spurs. By this contrivance the handle may be pulled over either way, the springs

page_text: giving way sufficient to allow it so doing, and by bearing down on the handle the
brush is lowered and caused to sweep hard when desired, the brush having been
previously set for all ordinary work by means of slot in brackets and set-screws."
The top central portion and the upper half of the sloping or inclined portions are
not quite so long as the remainder of cover, being cut away to avoid extending the
bail beyond the outer or extreme edge of the cover, and allowing room for the
working of bail from side to side. I insert India-rubber or such like substance set or
fastened in a groove formed in the edge of cover or so far as the extreme edge of case
extends, to act as a furniture protector.
The Carpet Sweeper is mounted on four wheels journalled to the outer surface of a
plate which are pivoted eccentrically to end-castings of the Sweeper, and provided
with a spring that normally holds its attached wheel in contact with friction bands,
upon ends of brush-roll, said plates adapted to receive positive movement towards
each other when downward pressure is applied to the Sweeper. The spring that keep
the wheels in contact with brush-roll has one end secured to the top inner side of
end-castings the other end is inserted in an eye formed in spurs of eccentric-plates
and are thereby insured from falling or springing off at the sudden jerk of the wheels
or the removing of Brush-roll.
The dust-pans are formed and arranged as in Patent granted to me as above
referred to, having their edges at right angles to each other, the lower end being
pivoted to end-castings, and kept closed or in position by means of a spring (fastened
to top end of dust-pans) dropping into a notch in end-castings.

I, BYRON HENRY EVERS of 110 Mercers Road, Upper Holloway London in the
County of Middlesex, Financial Agent, which invention has been communicated to
me from abroad by William H. Castle of State of Ohio, United States of America
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:
My invention has reference to further improvements in Carpot-sweepers to those
for which Letters Patent of Great Britain were granted to me bearing date
November 12th 1884 and numbered 14,907. My invention relates to improvements
in Carpet-sweepers in which the brush is rotated by driving-wheels running on the
floor and all within or attached to a box or case for the reception of the dust, and the
object of my invention is to regulate and adjust the brush to the various kinds of work
required for it, by means of pressure on the handle; and it consists of the construction,
combination and arrangement of parts substantially as hereinafter described and
pointed out in the claims. Similar letters of reference in the various figures of the
drawings denote similar parts.
Fig. 1, is an end view of my invention with a portion of the handle broken away
and also shows how the handle can be made to go over in either direction as shown
per dotted line.
Fig. 2, represents a longitudinal section, taken through one end on the lino xx
Fig. 1, and omitting the drive-wheel, and having the lower portion of the end-plate a
broken away; showing means for attaching the handle bail, the brush supports and
their relation to each other.
Fig. 3, is a section of the end-plate a showing the outer surface of the plate with
the indenture or notch t, for the reception of the spur or pins of Bail, also shows the
outer view of the opening for the reception of the trunnion 9 of Bail, and spring K;
besides showing the position of one of the eccentric-plates H (as in my previous
patent before mentioned) to which the drive-wheel 6 for propelling the rotary-brush is
pivoted.
Fig. 4, is an interior view of Figure 3, showing the opening for the reception of the
spring and Bail also the position of spring 1 for keeping the drive-wheel pressed
against the wheel of brush-roll..
Fig. 5, is a side view of the Bail or forked like attachment of my invention.
Fig. 6. represents a bottom plan view of a Carpet-sweeper embodying my improve-
ments, the Bail and a majority of the brushes having been removed.
In the drawing a represents the end-plate of the Sweeper-box or case and is
preferably of metal, b b are the driving-wheels; c the end of the brush-roll; d the
brush Hanger; e the Bail to which the handle B is attached, fg and h are the top and
two sides of the box or case, and are cut away from i to j to accommodate the Bail, and
the remaining portion of the sides g and h are allowed to project out over the driving-

page_text: wheels with rubber attached to their edges for the purpose of protecting Furniture
against the metal machinery parts. Referring more particularly to Fig. 2, K is a flat
spring bent in two right-angles, with one end fixed to the top of the case at I, and its
free end extending through the end-plate at m (the opening m is fully shown in Figs. 3
and 4,) and to which is attached the brush-support or hanger; n is a right-angle plate
riveted to the free end of the spring K and to which is attached the brush-hanger d by
means of the screw o. The Hanger d having near its lower end a hole or bearing for
the reception of the Brush-pin v, and its upper end a slot p, through which the screw o
is entered, and by means of which the brush may be raised or lowered as desired, this
adjustment being supplemental to the adjustment presently to be described.
It will be observed that the lower extremity of the Bail e terminates in an inwardly
projecting trunnion 9, and its inner end having AL flange or hook r; above the
trunnion 9 is an inwardly projecting pin or spurs which is also a part of the Bail e.—
t is a rib or flange projecting from the front upper edge of the end-plate a, and on its
underside and middle is an indenture or notch, shown more fully in Fig. 3,-u is a
flange, covering a portion of the opening m, also shown in Fig. 3.
The Trunnion of the Bail e is insorted into the opening m and the rib r engaging
with the flange u is prevented from springing out when in use, while it has room for a
desired verticle movement. The lower side of the Trunnion q rests on the angle-
plate and is wholly supported by the spring K; and by the upward pressure of the
spring K when the bail is perpendicular, the pin & engages with the notch or indentation
in the rib t, and the Bail and Handle B are thereby held in a vertical position when
the Sweeper is not in use. The Handle B is easily pulled over either way the spring K
yielding to admit of it, and any downward pressure on the handle acts directly on the
spring K, and it follows that by downward pressure on the handle, the relative position
of the brush to the floor may be changed vertically to accommodate it to the various
kinds of work required. And it will be observed that the spring K answers a double
purpose; to afford a vertical yielding support for the brush, and to support the handle
in an upright position when not in use.
I am aware that various modifications in the detail of construction can be mado
without departing from the principals or sacrificing the advantages of my invention,
the prefered means for carrying it out having having been shown and described and
I would therefore have it understood that I do not confine myself to the exact form
and construction shown.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed I declare that what I claim is :—
1st. In a Carpet-sweeper, the combination with the end-plate a spring K and
Hanger d, the Baile having the pin s, Trunnion q and retaining rib, substantially
as described.
2nd. In a Carpet-sweeper, the combination with the Bail e spring K and Brush-roll c
the End-plate a having the indented rib t, opening m and flange u substantially as
described.
3rd. In a Carpet-sweeper, the combination with the brush-roll c and End-plate a the
vertical yielding spring K angle-plate n adjustable-Hanger d and Bail e, substantially
as and for the purpose described.
