Improvements in Brushes for Sweeping, scouring, and the H
A communication from JoHN F. EBERT of New York in the County and State of
New York, United States of America, Gentleman.
I ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to that class of brushes in which the brush head is revolu-
ble with respect to the handle, and whereby those parts may be adjusted to different
relative positions, as required.
Generally speaking, the object aimed at in the manufacture of brushes of the
class above mentioned, is to produce means for reversing the wear upon the bristles,
so that in use they will remain straight and wear with an even surface, and also
to provide means for rendering the brush head available to work into corners, or
other places difficult of access.
Brushes of this class are generally adapted for use in sweeping walls and ceilings
of rooms, where they are likely to be employed about delicate and expensive
draperies; and should, for the reason, be entirely free from projections of any kind
likely to catch and injure the most delicate fabrics, such, for instance, as lace
hangings, or the like.
On account of the simplicity of construction and freedom from projections of
the kind referred to the ordinary wooden block, provided with a number of holes
to form sockets for a common handle is in more general use than any other brush
of the general class to which this invention belongs. It is found in practice, how-
ever, that unless such a brush block is made very thick and heavy it is impossible
to secure sufficient depth of the sockets in the block to insure a firm and sufficiently
permanent union between the handle and the block.
The object of this invention is to produce a simple, cheap, durable and effective
metallic device for uniting a handle to a brush block, in which the essential
characteristics of ready adjustability to all the positions required in practice, light-
ness in weight, and entire freedom from all projections, are present.
In the accompanying drawings:
Fig. I is an end elevation of a brush, showing a handle united thereto by
this device;
Fig. II is a side elevation of the brush, showing the handle adjusted at right
angles to the position shown in Fig. I;
Fig. III is a top plan view of the brush, with handle and connecting piece
removed;
Fig. IV is a bottom plan view of the socket piece disc or plate.
Referring to the figures on the drawings:
1 represents a brush block, of any suitable shape, size and dimensions, that is

page_text: provided, in any suitable and ordinary manner, with bristles 2 projecting from a
plane surface 3 in the ordinary way.
4 indicates the top of the brush block, which has a plane flat surface, preferably
parallel to the bottom 3 from which the bristles project.
5 indicates yielding bumpers which may secured by suitable means around
the ends of the brush block, and which serve to prevent injury to polished surfaces
by abrasion of the block against the same.
The foregoing description is applicable to a brush provided with the simplest and
most economical form of block.
6 indicates the disc or plate of the socket piece, which is preferably made of light
cast metal, for example, brass, and which is provided on one side with an oblique,
upwardly projecting socket 7, which, is of sufficient diameter and depth to receive
and securely hold a handle 8 of desirable size. The disc 6 is preferably flat and
simple in construction, and while of sufficient area to present a broad, flat surface
against the top of the brush block, does not extend beyond it.
Upon the opposing surfaces of the disc and the brush block, to wit, the top of
the block and the bottom of the disc, correlative projections and depressions, are
provided, which when the block and the disc are clamped together, serve to rigidly
secure the parts in those relative positions to which they have been previously
adjusted.
As illustrated, in the top of the block are provided elongated depressions 9
arranged radially around a central aperture 10.
In the bottom of the disc there is provided the single elongated rib 11, divided by
a central aperture 12, corresponding in size and position with the aperture 10 in the
block.
The shape, number and extent of the depressions in the brush block, and of the rib
upon the disc are obviously in no wise essential. It is sufficient that correlative
retaining mechanism upon the block and the disc, for preventing the rotation of
these parts when clamped together, be employed.
18 indicates a screw or bolt, and 14 a nut, countersunk in the bottom 3 of the
block, and adapted to receive the same. The head of the bolt 13 is made small and
circular in contour, so as to afford no projection upon which drapery may catch.
In practice, the disc is applied to the top of the block, and by the insertion of the
rib 11 into the required recess 9, the necessary adjustment is obtained. The
screw 13 having been inserted into the apertures 10 and 12, is screwed into
the nut 14 until the parts are firmly clamped together, when a permanent union of the
socket piece, block and handle, will have been effected.
In re-adjusting the socket piece upon the block, it is necessary only to loosen
the bolt so that the ribs 11 may be disengaged from the walls of the recess 9, where-
upon the brush head can be again adjusted and the parts united, as before.
Having now particularly described and ascertained the nature of this said inven-
tion, as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is :-
1. The combination with a flat top brush block, having an aperture therein
extending entirely through the same, of a socket piece provided with a disc, pro-
vided with a central aperture and adapted to lie flat against the top of the block,
an eccentrically located socket upon the socket piece, the central aperture in the
disc corresponding with the aperture in the block, correlative retaining mechanism
located upon the opposing faces of the disc and block, respectively, a bolt adapted
to enter the apertures in the disc and block, respectively, and a nut adapted to
receive. the end of the bolt upon the side of the block opposite the disc and unite
the parts together, substantially as set forth.
2. The combination with a brush block, having an aperture extending through
the same, of a socket piece provided with a flat disc having a central aperture and
an eccentrically located socket, the diameter of the disc being equal to, but not
greater than, the width of the block, correlative retaining mechanism upon the

page_text: faces of the disc and block, respectively, the aperture in the disc corresponding with
the aperture in the block, a bolt extending through the aperture in the disc and
block, respectively, and a nut upon the end of the bolt, substantially as set forth.
3. The combination with a brush block, having an aperture extending through
the same, of a socket piece provided with a disc having a central aperture, and a
socket located eccentrically thereon, the aperture in the disc corresponding with the
aperture in the block, depressions in the face of the block opposite the face of the
disc, a projection upon the face of the disc opposite the depressions in the block, a
bolt extending through the apertures in the disc and block, respectively, and a nut
upon the end of the bolt, substantially as set forth.
