GEORGE GOOD and WILLIAM HENRY GOOD, both of Yeovil, in the County of
Somerset, Patent Twine and Sailcloth Manufacturers. "IMPROVEMENTS IN THE
MANUFACTURE OF WATERPROOF CANVAS, SAILCLOTH, AND OTHER FABRICS, ALSO
IN PREPARING AND TREATING TWINES AND THREADS FOR SAIL MAKING AND
OTHER PURPOSES, AND IN THE MECHANISM AND APPARATUS EMPLOYED FOR THESE
PURPOSES,"
The first part of our Invention relates to improvements in the manufacture of
an improved waterproof canvas, sail-cloth, and other fabrics, and in special appliances
or apparatus employed in weaving such fabrics, thereby rendering them more
suitable for the purposes to which they are applied.
The threads or twines used in the manufacture of the said canvas, sail-cloth, and
other fabrics, are dressed previous to their being woven in the manner herein after
described, after which they may be used as follows:-
Firstly. In the weft only, which will render the fabrics waterproof whilst the
inner or waterproof portion is protected by the warp or outer portion.
Secondly. The warp only may be dressed.
Thirdly. Both warp and weft may be dressed, making the whole of the material
used waterproof.
The special appliances or apparatus consists of a self acting holder or nippers,
for the purpose of holding or securing the edges or selvages of canvas, sail-cloth,
and other woven fabrics whilst being woven, thereby securing an even selvage and
an uniform width of the material woven, and also to enable the weaving of
glutinous or damp materials.

page_text: This appliance or apparatus consists of an improved holder of peculiar con-
struction, and is to be secured to the loom, having its motion imparted to it by the
lathe or some other suitable part of the machinery, and is applicable to both hand
and power looms.
The appliance or apparatus for holding the edges or selvages is in the form of a
self acting pair of pincers, one part of which is fixed to the front part of. the loom.
The canvas or other fabrics is held in position by the jaws, which are kept closed
by a spring until the shuttle has passed; when they are opened by the lathe and
forced back by the reed, they return again with the reed and catch the last shoot -
made. In the outside of each jaw is a small opening in which is left free some
threads of the warp, round which the shoot doubles, thus securing an even selvage
and an uniform width of the material woven.
The second part of our Invention relates to improvements in preparing and
treating twines or threads for sailmaking and other purposes, and in the apparatus
employed therein, of the character described in the Specification of Letters Patent
granted to the said George Good, dated 18th December, 1874, No. 4362; and part
of our improvements consists of an improved tanning liquor composed of bark,
cutch, and gambier, to which is added a solution of coal tar by which the tan is
more firmly fixed in the fibres.
The twines or threads are first boiled in a solution of alkali to destroy the 1
perishable matter contained in the twine or threads, after which they are put into
a vessel containing the tanning liquor.
Another improvement is in the ingredients of the compound used in preparing
the twine or thread, which compound is composed of the following ingredients in
the quantities and proportions named, or thereabouts :-
Bees wax-
Linseed oil
India rubber solution
Gutta percha solution
Resin
Palm oil
Prepared tar
Pure crude oil
60 pounds.
1 gallon.
2 pounds.
6 pounds.
10 pounds.
24 pounds.
30 pounds.
1 gallon.
These ingredients not only render the twines or threads more durable, but keeps
them for a longer period in a better condition for use.
Another improvement relates to an improved arrangement of apparatus for
applying the ingredients to the twines or threads.
In describing the apparatus for applying the ingredients or compound to the
twine or threads, one part of our improvements consists in placing before the
apparatus two or more rollers covered with card wire to remove all nibs or refuse
from the twine or threads. Another improvement consists in dispensing with the
revolving agitator and placing the rollers, composed either of cork and hair, metal,
or other suitable substance, at the bottom of the bath containing the ingredients
or compound.
The twine or thread under operation is first passed from a creel of bobbins
through the carding rollers, and then into the bath containing the ingredients or
compound passed between the rollers, and then through spring nippers on to reels
or bobbins, and thence to the balling or warping machine.
By this improved apparatus the twines or threads are not only better and more
evenly dressed, but any number of threads can be done at the same time without
breakage or waste.

the said George Good and William Henry Good in the Great Seal Patent
Office on the 10th November 1881.
GEORGE GOOD and WILLIAM HENRY GOOD, both of Yeovil, in the County of
Somerset, Patent Twine and Sail-cloth Manufacturers. "IMPROVEMENTS IN THE
MANUFACTURE OF WATERPROOF CANVAS, SAIL-CLOTH, AND OTHER FABRICS, ALSO
IN PREPARING AND TREATING TWINES AND THREADS FOR SAIL MAKING AND
OTHER PURPOSES, AND IN THE MECHANISM AND APPARATUS EMPLOYED FOR THESE
PURPOSES."
The first part of our Invention relates to improvements in the manufacture of
an improved waterproof canvas, sail-cloth, and other fabrics, and in special
appliances or apparatus employed in weaving such fabrics, thereby rendering them
re suitable for the purposes to which they are applied.
The threads or twines used in the manufacture of the said canvas, sail-cloth, and
other fabrics, are dressed previous to their being woven in the manner herein after
described, after which they may be used as follows:-
Firstly. In the weft only, which will render the fabrics waterproof whilst the
inner or waterproof portion is protected by the warp or outer portion.
Secondly. The warp only may be dressed.
Thirdly. Both warp and weft may be dressed, making the whole of the material
used waterproof.
The special appliances or apparatus consists of a self acting holder or nippers for
the purpose of holding or securing the edges or selvages of canvas, sail-cloth, and
other woven fabrics whilst being woven, thereby securing an even selvage and an
uniform width of the material woven, and also to enable the weaving of glutinous
or damp materials.
This appliance or apparatus consists of an improved holder of peculiar con-
struction, and is to be secured to the loom, having its motion imparted to it by the
lathe or some other suitable part of the machinery, and is applicable to both hand
and power looms.
The appliance or apparatus for holding the edges or selvages is in the form of a
self acting pair of pincers, one part of which is fixed to the front part of the loom.
The canvas (or other fabrics) is held in position by the jaws A (as represented at
Figure 1 of the Drawings hereto annexed), which are kept closed by a spring until
the shuttle has passed; when they are opened (as shown at B, Figure 2) by the
lathe striking against the arin C, and forced back by the reed, they return again
with the reed and catch the last shoot made. In the outside of each jaw is a small
opening F, in which is left free some threads of the warp, round which the shoot
doubles, thus securing an even selvage and an uniform width of the material woven.
In the side of the apparatus there is a moveable plate E for adjusting the apparatus
for different sized threads.
The second part of our Invention relates to improvements in preparing and
treating twines or threads for sail making and other purposes, and in the apparatus
employed therein, of the character described in the Specification of Letters Patent
granted to the said George Good, dated 18th December, 1874, No. 4362; and part
of our improvements consists of an improved tanning liquor composed of about
2 pounds of bark, one pound of cutch, and one pound of gambier, or thereabout,
to which is added about one pint of a solution of coal tar, by which the tau is
more firmly fixed in the fibres.

page_text: The twines or threads are first boiled in a solution of alkali (from 4 to 5 per
cent. in strength) to destroy the perishable matter contained in the twine or threads,

more durable, but
These ingredients not only render the twines or threads
keeps them for a longer period in a better condition for use.
Another improvement relates to an improved arrangement of apparatus for
applying the ingredients to the twines or threads.
In describing the apparatus for applying the ingredients or compound to the
twine or threads one part of our improvements consists in placing before the
apparatus two or more rollers covered with card wire to remove all nibs or refuse
from the twine or threads. Another improvement consists in dispensing with the
revolving agitator and placing the rollers, composed either of cork and hair metal,
or other suitable substance, at the bottom of the bath containing the ingredients or
compound.
The twine or thread under operation is first passed from a creel of, bobbins G
(Figure 2), through the carding rollers F (Figures 3 and 4), and then into the
bath A. containing the ingredients or compound, passed between the rollers D, and
then through spring nippers B on to reels or bobbins H, and thence to the balling
or warping machine.
By this improved apparatus the twines or threads are not only better and more
evenly dressed, but any number of threads can be done at the same time without
breakage or waste.
Having thus described the nature of our Invention, and the manner of per-
forming or carrying the same into practice, we would remark that we do not
limit ourselves to the exact details herein before described for putting our Invention
into practice so long as the main features of our Invention are retained, at the
same time we do not claim any of the mechanical parts or ingredients separately,
which are well known and in common use, but what we claim is,-
