IMPROVEMENTS IN THE MANUFACTURE OF BRUSHES
Year: 1880

page_text: LETTERS PATENT to Samuel Abraham, of Manchester, in the County of
Lancaster, Brush Manufacturer, Cornbrook, Manchester, for an Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF BRUSHES."
PROVISIONAL SPECIFICATION left by the said Samuel Abraham at the
Office of the Commissioners of Patents on the 4th September 1880.
SAMUEL ABRAHAM, of Manchester, in the County of Lancaster, Brush Manu-
facturer, Cornbrook, Manchester. "IMPROVEMENTS IN THE MANUFACTURE OF
BRUSHES."
This Invention has for object improvements in the manufacture of brushes, and
consists in combining with the hair or fibrous bristles ordinarily used in such
manufacture, hardened and tempered brass wires of suitable thickness.
One mode of carrying out my Invention is to arrange the bristles alternately
with brass wires of from 34 to 38 Birmingham wire gauge hardened and tempered,
such wires being suitably secured. It will be evident however that my Inven-
tion may be carried out in various ways without departure from its essential
characteristic.

by the said Samuel Abraham in the Great Seal Patent Office on the
1st March 1881.
SAMUEL ABRAHAM, of Manchester, in the County of Lancaster, Brush Manu-
facturer, Cornbrook, Manchester. "IMPROVEMENTS IN THE MANUFACTURE OF
BRUSHES."
This Invention has for object improvements in the manufacture of brushes, and
according thereto I use in conjunction with the hair, bristles, or fibres ordinarily
used in such manufacture wires, or metallic threads,, or filaments, as hereinafter
described. In practice I find it advantageous to use brass wires which may
conveniently be of from 34 to 38 Birmingham wire gauge, hardened and tempered.
According to one mode of carrying out my Invention the wires are mixed in the
same tufts with ordinary bristles or fibres, the tufts so composed being doubled and
secured in the brush stock or head by wire in a usual manner. In a brush there
may be an outer row or rows of tufts composed of bristles or fibres only without
admixture of wires.
It will be obvious that to suit different purposes the proportion of wires to
bristles may be varied, also that some of the tufts may be wholly of wire, others
being either partially or wholly of bristles or fibres. Thus according to one modifi-
cation I make a brush with rows of tufts all composed of hair or fibres alternating
with rows of tufts entirely of wires.
Another modification consists in making the brush with the alternate tufts of
bristles and of wires respectively.
Wires, or metallic threads, or filaments serving as bristles as described, may be
used in conjunction with bristles or fibres.secured to stocks otherwise than as above
set forth, as will be readily understood. For example, where bristles of the full
length are used the roots of such bristles being inserted in the brush head, wires
may be used either in single lengths, or doubled as in the above arrangements.
Having described the nature of my said Invention, and explained in what
manner it is to be carried into practical effect, it is to be noted no general claim is
made to the use of wire in the manufacture of brushes, but what I do claim as
secured to me under the Letters Patent herein-above in part recited is the manu-
facture of brushes in which wires, or metallic threads, or filaments are combined
with ordinary bristles or fibres, substantially as hereinabove described.
In witness whereof, I, the said Samuel Abraham, have hereunto set my
hand and seal, this Twenty sixth day of February, in the year of our Lord
One thousand eight hundred and eighty one.
SAMUEL ABRAHAM. (L.S.)
