Im- PROVEMENTS IN APPARATUS FOR PREPARING WARPS FOR THE LOOM
Year: 1869

page_text: LETTERS PATENT to William Strang, of Glasgow, in the County of
Lanark, North Britain, Manufacturer, for the Invention of "Im-
PROVEMENTS IN APPARATUS FOR PREPARING WARPS FOR THE LOOM."
Scaled the 22nd March 1870, and dated the 24th September 1869.
PROVISIONAL SPECIFICATION left by the said William Strang at the
Office of the Commissioners of Patents, with his Petition, on the
24th September 1869.
I, WILLIAM STRANG, of Glasgow, in the County of Lanark, North
Britain, Manufacturer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN APPARATUS FOR PREPARING WARPS FOR THE LOOM,"
to be as follows, that is to say :-
This Invention relates to novel appliances whereby warps may be
dressed and beamed or beamed only in an improved manner.
The improvement relating to dressing is applicable to apparatus of the
kind known as "tape" dressing machines, or other similar apparatus,
in which the warps after being served with size, starch, or other dressing

page_text: are dried by passing over one or more heated cylinders, and it consists
in arranging a revolving brush supplied in any convenient way with
melted tallow or other lubricant, to act on the warps after they leave the
drying cylinder and before they are wound upon the beam. The final
application of a lubricant in this way removes the harshness which the
drying imparts to the warps.
The improvement relating to beaming is applicable to the appliances
used in what is known as the "slashing" method of beaming, in which
the warps pass between a series of flat upright pins just before running
upon the beam. These pins have to be somewhat widely spaced to allow
knots or inequalities to pass through, and several warp threads pass
through each space and are apt to become entangled. The improvement
consists in inclining the pins at a slight angle from the vertical, and in
fixing them with their flat surfaces slightly inclined as considered in the
horizontal plane from the longitudinal lines of the warp threads. Leasc
rods are used to divide the warps just before they pass the pins, and the
action of the inclination or twist of the pins is to properly spread and
separate the warp threads, so that they do not cross each other as they
run upon the beam. The beaming is rendered much superior to the
ordinary slashing process, and even better than when the warps are
passed through heddles or reeds at the entering end of the dressing
machine.
By another modification a reed formed with heddle threads or other
suitable threads instead of metal splits is used, the threads being
sufficiently elastic to allow of the passage of knots or inequalities.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Strang in the Great Seal Patent Office
on the 23rd March 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
STRANG, of Glasgow, in the County of Lanark, North Britain, Manu- 3
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of September, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors, 3

page_text: give and grant unto me, the said William Strang, Her special licence
that I, the said William Strang, my executors, administrators, and
assigns, or such others as I, the said William Strang, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, usc, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR PREPARING WARPS," upon the condition (amongst others)
that I, the said William Strang, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Strang, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accom-
panying Drawings, that is to say :-
My said Invention relates to novel appliances whereby in the process
of preparing warps for the loom they may be dressed. and beamed or
beamed only in an improved manner.
My improvement in the dressing part of the process consists in
arranging a revolving brush supplied in any convenient way with melted
tallow or other lubricant to act on the warps after they leave the drying
cylinder of a "tape" dressing or similar machine, and before they are.
wound on the beam. The final application of a lubricant in this way
removes the harshness which the drying imparts to the warps.
My improvement relating to beaming consists in imparting a peculiar
inclination or twist to the flat pins used in the "slashing" method of
beaming, in consequence of which the pins properly spread and separate
the warp threads, so that they do not cross each other as they run upon
the beam. The beaming is thereby rendered much superior to the
ordinary slashing process, and even better than when the warps are
passed through heddles or reeds at the entering end of the dressing
machine.

page_text: .
By another modification a reed formed with heddle threads or other
suitable threads instead of metal splits is used, the threads being
sufficiently elastic to allow of the passage of knots or inequalities.
And in order that my said Invention, and the manner of performing
the same, may be properly understood, I have hereunto appended a Sheet
of explanatory Drawings, to be herein-after referred to, and representing
the manner in which I prefer to carry out my improvements.
Figure 1 is a longitudinal vertical section of the terminal or beaming
end of a "tape" dressing and beaming machine; and Figures 2, 3,
and 4 are enlarged views at right angles to each other of the improved
inclined or twisted dividing pins or splits.
As the general construction and arrangement of the dressing and
beaming machine is well known it will be unnecessary to describe more
than the parts added in order to carry out my improvements.
The warps are shown by blue lines 1, as on their way to the beam 2
from the drying cylinders, which latter are not shown. The lubricant to
be applied to the warps is contained in a trough 3 heated, if necessary,
by steam pipes 4, and is taken up by a revolving brush 5 (or it might be
a plain or covered roller), which transfers it to a revolving brush 6, this
last applying it to the warps 1 as they pass along over it. The warps 1
after leaving the lubricating brush 6 pass on over and under three lease
rods 7, 8, 9, by which they are separated into sections; and these lease
rods are carried by adjustable holders 10, 11, 12, their nice adjustment
being essential to the proper action of the splits or pins 13, through
which the warps next pass. These splits or pins consist of flat wires or
strips of metal, and are held in a compound bar 14 consisting of two
parts bolted together. The parts of the splits held in the bar are placed
at right angles to the bar for convenience of holding, being spaced in
the ordinary way by coiled wires, and the desired inclination is given
them by twisting the parts above the bar, and will be easily understood
on comparing the three Figures 3, 4, and 5. There is, as in ordinary
machines, sufficient space between each pair.of splits for several threads
to pass, and also to allow of the easy passage of knots or inequalities;
but instead of the set of threads passing between any pair of splits
being, as it were, bundled together, as in ordinary machines, involving
the frequent intercrossing and entangling of the threads, they are spread
and separated by running over the inclined surface of the splits, just as
if they were passing through a reed with as many splits as threads. The

page_text: bar 14 is capable of adjustment across the machine by means of a screw
and hand wheel 15, so that the warp threads may be made to bear more
or less against the sides of the splits, as may be found desirable in
practice.
Having thus particularly described my said Invention, and the manner
in which the same is to be performed, I have to state that I do not
restrict myself to the precise details herein described or delineated; but
that what I believe to be novel and original, and claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,-
1. The fitting of warp preparing apparatus with appliances for treating
the warps with lubricating matter after they leave the drying cylinders,
substantially as herein-before described.
2. The using of inclined or twisted pins or splits for spreading and
separating the warp threads as they pass upon the beam, substantially
as herein-before described.
In witness whereof, I, the said William Strang, have hereunto set
my hand and seal, this Twenty-second day of March, in the year
of our Lord One thousand eight hundred and seventy.
