OR MANUFACTURE OF BROOMS BRUSHES AND SIMILAR
ARTICLES [A communication to him from abroad by J Gontier, of Grenoble,
in the Republic of France]
This invention relates to improvements in the construction or manufacture of
brooms brushes and the like for various purposes
A broom for sweeping streets and the like is made according to this invention as
follows vis―
The bundles of piassava-grass or the like are prepared as usual, their upper ends
being tied ready for insertion in the stock. The bundles of fibre are placed in a
close row between two strips of wood or other suitable material the lower part
whereof is somewhat thicker than the top so that the stock has a firm hold upon
the fibre-bundles The two strips with the fibres between are firmly united by
screws or pins and hot molten pitch poured into the open space so as to set round
the bundles of fibre and to fill the empty spaces. A third tapering strip of wood is
then fitted into the space between the two first strips and being fixed by screws or
pins forms the top of the stock. The two ends of the stock are provided with
metal (preferably iron) corner pieces or ferrules and between the corner pieces and
the stock adjustable metal guards are inserted so as to compress the lower part of

the insertion of the broom handle.
A broom for sweeping rooms and for similar purposes may be made of piassava,
bristles or the like.
The side and top pieces of the stock have a raised part on the top in which a
hole is made for the handle On the edges, sides and ends of the stock (but not at
the top) holes are drilled for the insertion of hunches or bundles of fibre say by

to increase the quantity of fibre in the broom and give it a better shape without
increasing the size of the stock and the rows at the sides and ends to prevent
injury to furniture & with which the broom may be brought in contact.
If desired strips of india rubber or of some pile fabric may be employed instead

that above described. Should it be desired two rows of fibre may be placed at the
centre of the broom and in this case a strip corresponding to the sides of the stock
is placed in the centre. The number of rows may in the same manner be increased
and two or more centre pieces used. If the broom is to be used for washing floors
provision will be made for attaching the handle at one side and the other may be
fitted as above described for the protection of furniture &o.
The body of the stock may if preferred be made in one piece with one or more
recesses for the insertion of the rows of fibre ready tied in bunches or bundles and
have open ends for this purpose and these may be afterwards closed up by suitable
end pieces.
Hand brushes according to this invention are preferably made in the last
described manner.

by the said Alfred Julius Boult in the Great Seal Patent Office on the
10th February 1883.
ALFRED JULIUS BOULT of the firm of W. P. Thompson and Boult Agents for
Foreign Patent Solicitors of 323 High Holborn in the county of Middlesex and
6 Lord Street Liverpool in the county of Lancaster Engineer "IMPROVEMENTS
IN THE CONSTRUCTION OR MANUFACTURE OF BROOMS, BRUSHES, AND SIMILAR
ARTICLES." A communication to me from abroad by J Gontier, of Grenoble, in the
Republic of France
In the accompanying drawings Fig 1 is a side elevation, Fig 2 an end elevation,
and Figs 3 and 4 vertical cross sections of a brush or broom for sweeping roads
and the like Fig 5 is a side view and Figs 6, 9 and 10 are vertical cross sections
of a brush or broom for sweeping rooms. Fig 11 is a brush with short bristles for
scrubbing floors and Figs 7 and 8 are an elevation and section of a hand brush.
The bundles of piassava grass J, before hand tied at their upper ends, are
introduced in close rows between the two plates A A. These bundles will be
sufficiently compressed between the two plates A, A, by the screws E then boiling
pitch is poured in, which will encase the tops of the bundles J and fill the recesses
between them and the plates A A and whilst the pitch is yet hot, the piece C is
placed on and forms a key which by the screws E is pressed between the plates A A.
The ends are fitted with iron fittings D. A moveable resistance piece G preferably
of iron lies flat upon the ends of the broom between the iron fitting D and the two
plates A A in a recess formed in key C and is bent to a knee across the face of the
broom and lying flat against it; to regulate this resistance piece G and to prevent
its falling small holes I are provided in its turned back ends and receive a small
wooden pin H; an iron socket F receives the handle. Fig 4 is a modification of
Fig 3 the piece C being dispensed with and the two plates A A being brought close
together at the top
"
BROOMS FOR SWEEPING ROOMS.
This broom is made of piassava grass or other suitable material such as
chiendent," or tampico," pigs bristles &c. The plates A A and the piece C is cut
out in such a manner as to form an elevation in the middle of the broom where
there will be a hole to fix the handle as shown in Fig 5. On the edges of the
plates, on the faces, and the ends there are rows of small holes filled with bristles or
the like fixed either by wires or pitch. The object of these small holes at the
edges of the plates is to form two rows L which impart to the broom greater fulness
and more grace without requiring therefor a greater volume of wood, and those at
the faces and ends forin a row K to protect the furniture. For simplicity the row K
can be dispensed with and the ends furnished with a covering of rubber or velvet
or the like These details are at the option of the manufacturer. If two inner
rows are to be attained a small plate N will be added, mounted in the same manner,
and the same means as above set forth with regard to the Street Broom (see the
section of the broom in three pieces Fig 10 with the two plates N on the interior)
The broom having only one inner row can be made in two pieces and the edges
faces and ends may also be fitted with bristles the two pieces being in any case
united by the screw E, see the section of the broom stock made in two pieces
Fig 6

page_text: BRUSH FOR SCRUBBING FLOORS. Fig 11.
A hole will be made on one side to attach a handle. To protect the furniture
one or several bundles of fibre K may be fixed thereon; the manufacture being as
above stated.
All these divers articles may be made in a single piece having one groove for
one row, two grooves for two rows &c the brush material, tied beforehand being
inserted from the ends, see section M. Fig 9 of the broom made in a single piece
By this latter means hand brushes may also be made and the plates N may be
surrounded with bristles O or the like as shown in Fig 8 which is a section of the
hand brush.
Having now described this invention as communicated to me by my foreign
correspondent, I claim
The improvements in the manufacture of brushes, brooms and the like
substantially as hereinbefore set forth and illustrated in the accompanying
drawings.

In witness whereof I the said Alfred Julius Boult have hereunto set my
