IMPROVEMENTS IN LOOMS AND IN APPARATUS CONNECTED THEREWITH
Year: 1861

page_text: LETTERS PATENT to John Holden, of the City of Manchester, in the
County of Lancaster, for the Invention of "IMPROVEMENTS IN LOOMS
AND IN APPARATUS CONNECTED THEREWITH."
Sealed: the 12th September 1861, and dated the 16th March 1861.
PROVISIONAL SPECIFICATION left by the said John Holden at the
Office of the Commissioners of Patents, with his Petition, on the 16th
March 1861.
I, JOHN HOLDEN, of the City of Manchester, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LOOMS AND IN APPARATUS CONNECTED THEREWITH," to be as follows:-
Firstly, I attach to the lathe of the loom a lever worked by an inclined
plane to raise the weft from the shuttle board, so as to enable the weft fork to
catch the thread of weft, dispensing with the necessity of a nick or slot in the
shuttle board, by which plan wheeled shuttles can traverse the shuttle board
without being impeded in their course.
Secondly, I use an elastic or other break worked from the stop rod, and
which acts upon the centre of the bottom of the lathe.
Thirdly, for self-acting temples I cover the top or pressure roller with caout-
chouc or other elastic substance which works on the top part of the under
roller, and is pressed down upon it by means of a set screw, with an adjusting

page_text: screw beneath the lid to regulate the pressure; or, if desirable, I cover both
rollers with an elastic substance.
Fourthly, I attach a serrated slide to the front of the temple, worked by a
compound lever and an inclined plane attached to the lathe.
Fifthly, I raise teeth upon the bottom roller by means of a die and the use
of pressure from a pair of clams.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Holden in the Great Seal Patent Office on the
16th September 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOLDEN, of the City of Manchester, in the County of Lancaster, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Holden, Her special licence that I, the said John Holden,
my executors, administrators, and assigns, or such others as I, the said
John Holden, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN LOOMS AND IN APPARATUS CONNECTED THEREWITH," upon the condition
(amongst others) that I, the said John Holden, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Holden, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say).:-
This Invention consists, firstly, in an improved arrangement for enabling the
weft motion to be employed in connection with wheeled shuttles. The ordinary

page_text: groove in the shuttle board is dispensed with, and there is only a narrow groove
to allow a lever to work in, so that when the lever is down its upper edge is
perfectly level with the shuttle board, and enables the wheels of the shuttle to
pass over freely. The said lever is for the purpose of raising the weft thread
so that it may act upon the weft fork, and the lever is put in motion by its
coming in contact as the lathe comes forward with an inclined plane attached
to the breast beam, the lever being lowered into the groove of the shuttle
board by means of a spring when the lathe moves backwards.
Secondly, I use an elastic or other break worked from the stop rod, other-
wise called the spring handle, which break acts upon the centre of the bottom
of the lathe and stops the loom when the strap is thrown off. To the said
stop rod or handle there is jointed a rod connected to one arm of a bent lever,
on the other arm of which there is an india-rubber ball or other elastic mate-
rial. The lever works on a stud fixed to the breast beam, at such a distance
that when the spring handle is released and gives motion to the rod and lever,
the elastic end shall come in contact with the bottom of the lathe as it beats
up and stop the loom, as before described.
Thirdly, in one arrangement of self-acting temples I cover the top or pressure
roller with caoutchouc or other elastic substance, which works on the top part
of the under rollers, and is pressed down upon them by means of a set screw
with an adjusting screw beneath the lid to regulate the pressure, or, if desir-
able, I cover all the rollers with india-rubber or other elastic substance.
Fourthly, in another arrangement of self-acting temple I attach a serrated
or toothed slide to the front of the temple worked by levers, one of which is
acted upon by an inclined plane connected to the lathe.
And, fifthly. I raise teeth upon the bottom rollers of the temples by means of
a die and the use of pressure from a pair of clams or other machine, so that
teeth of any required size are milled or formed upon the rollers.
In order that my improvements in self-acting temples may be clearly under-
stood, I annex the accompanying Sheet of Drawings with the figures and
letters of reference thereon; the other parts of my Invention are so plain and
self-evident as to need no further description.
Fig. 1 is a transverse elevation; and Fig. 2, a transverse section of one
of my improved arrangements of self-acting temples; and Fig. 3, a plan of the
under side of the lid or cover.
The top or pressure roller is shewn at a, it is covered with caoutchouc or
other elastic substance, and works on the top part of the two under rollers b
and c.
The roller a is pressed down by the set screw d, and its required
position is adjusted by the adjusting screw e, upon which the lid rests. I also,

page_text: when desired, substitute for the toothed rollers b and c rollers covered with
india-rubber or other elastic substance..
Fig. 4 is a transverse elevation; Fig: 5, a transverse section; Fig. 6, a
longitudinal elevation; and Fig. 7, a plan with the lid removed of the other
of my improved arrangements of self-acting temples.
To the front of the temple I place a serrated or toothed slide f, guided in
the temple head. To the slide is connected the lever g, fixed to the shaft h;
which works in the bearings i on the temple head. Fixed to the shaft h is
another lever k, so placed that an inclined plane or cam attached to the lathe
shall come in contact with it, and thereby give motion to the lever g and draw
out the serrated slide and stretch the fabric, a spring being employed to take
the serrated or toothed slide back again, the aforesaid stretch taking place at
each beat up of the lathe.
Having now described the nature and particulars of my said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim as 'my Invention the improvements in looms and apparatus con-
nected therewith, as herein described and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, I, the said John Holden, have hereunto set my
hand and seal, this Fourteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-one.
Signed, sealed, and delivered, by the
within-named John Holden, in the
presence of

JOHN HOLDEN. (L.s.)
