IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1867

page_text: LETTERS PATENT to Robert Carter, of Leyland, near Preston, in the
County of Lancaster, Overlooker, for the Invention of "IMPROVEMENTS
IN LOOMS FOR WEAVING."
Sealed the 6th March 1868, and dated the 26th October 1867.
PROVISIONAL SPECIFICATION left by the said Robert Carter at the
Office of the Commissioners of Patents, with his Petition, on the
26th October 1867.
I, ROBERT CARTER, of Leyland, near Preston, in the County of Lancaster,
Overlooker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LOOMS FOR WEAVING," to be as follows:-
The objects of this Invention are to cause the yarn to weave easier by
reducing the friction on the healds and reed, and also the friction on the yarn
itself, and at the same time to effect a saving in the power necessary for
driving the loom.
The Invention consists in placing the back carrier or rest on spiral springs

page_text: supported by studs or pins and brackets fixed to the side frames of the loom,
so that the springs and carrier or rest will yield to the pressure of the yarn
and thus reduce the friction upon the healds and reed, as well as upon the
yarn itself, and thus cause the yarn to weave easier as well as economize the
power required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Carter in the Great Seal Patent Office on the
25th April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
CARTER, of Leyland, near Preston, in the County of Lancaster, Overlooker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of October, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me,
the said Robert Carter, Her special licence that I, the said Robert Carter,
my executors, administrators, and assigns, or such others as I, the said
Robert Carter, 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, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING," upon the condition (amongst others) that I, the said Robert Carter,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 Robert Carter, 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 in writing, aud on reference to the accompanying Sheet of Drawings,
that is to say:-
The objects of this Invention are to cause the yarn to weave easier by

page_text: "
reducing the friction on the healds and reed, and also the friction on the yarn
itself, and at the same time to effect a saving in the power necessary for
driving.
The Invention consists in placing the back carrier or rest on spiral springs
supported by studs or pins and brackets fixed to the side frames of the loom,
so that the springs and carrier or rest will yield to the pressure of the yarn
and thus reduce the friction upon the healds and reed as well as upon the
yarn itself, and thus cause the yarn to weave easier as well as economize the
power required.
Such being the nature and object of my said Invention for " Improvements
in Looms for Weaving," I will now proceed to describe more in detail the
manner in which the same is to be or may be performed or carried into
practical effect, and in order that the same may be distinctly understood J
have annexed hereunto a Sheet of Drawings illustrative thereof, and have
marked the same with figures and letters of reference corresponding with those
in the following explanation thereof, that is to say :-
Figure 1 on the annexed Drawing is a back view of so much of a power
loom as is necessary for the illustration of my Invention, which is shown as
applied thereto; Fig. 2 is a cross section, and Fig. 3 a ground plan of the
same.
a, a, are the side frames of the loom; b, b, the yarn beam; and c, c, the
back carrier over which the yarn passes from the yarn beam to the healds d, d.
Bolted firmly to the two side frames are two brackets e, e, in which are fixed
vertical studs or pins f,f; resting on these brackets and coiled round the
studs are placed helical or spiral springs 9, 9, and upon the upper ends of these
springs rest loosely the ends of the back carrier c, c, the ends of the carrier
being pierced with holes fitting loosely over the studs or pins for that purpose.
By this arrangement and construction of the parts the springs and carrier will
yield to any undue pressure on the yarn and thus prevent any breakage, and
by reducing the friction cause the yarn to weave easier as well as economise
the power required to drive the boom. The springs also can easily be replaced
or renewed when required, and springs of different strengths may be adapted
for different kinds of work by merely lifting the back carrier off the studs.
Having now described the nature and object of my said Invention for
Improvements in Looms for Weaving," together with the manner in which
the same is to be or may be carried into practical effect, I would remark in
conclusion that I claim as my Invention the arrangement and combination of
the brackets, studs, spiral springs, and back carriers in the manner and for

page_text: the purposes herein-before particularly set forth and shown in the annexed
Drawings.
In witness whereof, I, the said Robert Carter, have hereunto set my
hand and seal, this Eighteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-eight.
ROBERT CARTER. (L.S.)
