Improvements in the Production of Impressing Patterns for the
Surface Ornamentation of Leather Tops of Cycle Saddles, and in
the Method of Applying such Patterns.
We, JOHN BOULTBEE BROOKS, Managing Director, and JOHN HOLT, Works
Manager, of J. B. Brooks and Company Limited, Criterion Works, Great Charles
Street, in the City of Birmingham, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the production of impressing patterns for the surface
ornamentation of the leather tops of cycle saddles, and also to the method of
applying such patterns to the surface of goods or articles produced by a blocking
process.
According to our invention, an impressing pattern or pattern-plate is pro-
duced by taking a plain surface and engraving chasing or cutting upon the same
a sunken or she-pattern which is identical with the impressed pattern that it is
desired to produce upon the surface to be ornamented, and produce therefrom
by electrotyping a counter-part of the ornament on the he or impressing pattern
plate. The said electrotype has raised parts corresponding to the sunken or
incised portions of the engraved surface, and constitutes the impressing or acting
face of the pattern plate, the back of which must be filled in to support the raised
parts, when in use.
In applying such pattern plates to the ornamentation of the surfaces of leather
cycle saddles produced by what is known as a blocking process, we introduce
the he side of the impressing plate upon the face of the leather blank with the
said leather blank and the impressing plate coming between the blocking die and
its engaging force. Then on applying pressure the ornamentation of the top
surface thereof by the pattern plate, is effected.

page_text: Street, in the City of Birmingham, 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:-
This invention relates to the production of impressing patterns for the surface
ornamentation of the leather parts of cycle saddles and also to the method of
applying such patterns to the surfaces of the said cycle saddles.
According to our invention, an impressing pattern or patterning plate is pro-
duced by taking a plain surface, such as a steel plate, and engraving, chasing
or cutting upon the same, a sunken or incised pattern which is identical with
the impressed pattern that it is desired to re-produce upon the article to be
ornamented.
From this engraved or sunken plate which constitutes the master pattern or
prototype, we obtain an electrotype counterpart or fac-simile in relief, which is
employed, in conjunction with suitable tools, as an impressing or patterning
plate for imparting to a leather blank, ornamentations in intaglio, corresponding
to those of the original pattern.
The electrotyped patterning plates are produced in the ordinary way from the
master pattern, to which a coating of some suitable substance is applied, to
prevent the adhesion of the counterpart, and sufficient metal is deposited to
produce a plate of substantial thickness, whilst if necessary, in order to strengthen
the plate and to support such parts thereof as may be in high relief, a suitable
filling or backing may be applied thereto.
Figure 1 of the accompanying drawings represents a plan of a patterning plate,
bearing upon its acting face, an ornamental design in relief, adapted for the
surface ornamentation of the tops of leather cycle saddles and produced by
electrotyping direct from an incised or sunken prototype or master pattern in
accordance with our invention.
Figure 2 is a longitudinal section of the said plate, which is marked A, and is
provided upon the underside with two or more pegs such as a¹, for setting the
same relative to the blocking tools, as hereinafter described.
In applying patterning plates so produced to the ornamentation of the surfaces
of leather cycle saddle tops which are produced, fashioned or shaped by the
well-known "blocking" process, the said plate is placed in the bottom of the
she-die, with its relief-ornamented side or acting face coming uppermost, and
with the leather blank which is to be ornamented or both blocked into shape
and ornamented, coming above the plate, to which the side to be patterned is pre-
sented and between it and the top die or blocking force. Then on the application
of pressure by the descent of the said force, the ornamentation, or both the
shaping of the blank and the ornamentation of the top surface thereof in intaglio,
are simultaneously effected.
Figure 3 represents a plan of the said bottom or she-die, with the accessory
fittings for holding the leather blank, removed, but showing the impressing
plate set within the bottom thereof.
Figure 4 represents partly in front elevation and partly in cross section, a
blocking or shaping press, showing the force or top die raised and the patterning
plate lying, acting face uppermost, upon the bottom of the she-die.
Figure 5 is another view, partly in side elevation and partly in longitudinal
section, of the said press but showing the force as descended into the bottom die
and effecting the ornamentation or both the blocking and the ornamenting of a
leather blank confined between it, the she-die and the patterning plate.
"
In the said Figures 3, 4 and 5, A is the patterning plate, 6 the she or lower
blocking die, suitably mounted in the bed c', of the press c and within which the
said plate is "set in its assigned position by means of the pegs w¹, on the one
part engaging into holes b', on the other. d is the upper die or force, which
is connected with the operating pressure screw e, having a hand wheel e¹, and

page_text: passing through a screw box f¹, in the framing f of the press, whilst 9 is the
blank under operation.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
First Ornamenting the surfaces of cycle saddles by the employment of a
patterning plate electrotyped or taken from a master pattern or prototype.
Secondly-Ornamenting the surface of cycle saddles by the employment of
a patterning plate, electrotyped or taken from a master pattern or prototype and
placed within the she or bottom die of a blocking press, substantially as herein
described and set forth.
