IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1868

page_text: LETTERS PATENT to Scipio Brook and Charles Thompson, of Halifax,
in the County of York, Worsted Manufacturers, for the Invention
of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 22nd May 1869, and dated the 25th November 1868.
PROVISIONAL SPECIFICATION left by the said Scipio Brook and
Charles Thompson at the Office of the Commissioners of Patents,
with their Petition, on the 25th November 1868.
We, SCIPIO BROOK and CHARLES THOMPSON, of Halifax, in the County
of York, Worsted Manufacturers, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be, as
follows:-
This Invention relates to means of acting upon the "swell" in looms
for weaving so as not to press upon the shuttle at any time except
immediately after the said shuttle has got into the box, and which is
relieved again before the said shuttle is "picked" or sent out of the box.
This is effected by means of a lever hinged to the back part of the loom
and extending over the crank shaft and under the lathe or going part of
the loom. A bracket with a friction roller is fixed on the stop rod catch,

page_text: the roller of which is placed over the lever, and a cam is fixed on the
crank shaft under the said lever, which as the said crank shaft rotates
acts upon the lever and also on the stop rod, and consequently on the
-swell in like manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Scipio Brook and Charles Thompson in the Great
Scal Patent Office on the 25th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SCIPIO
BROOK and CHARLES THOMPSON, of Halifax, in the County of York,
Worsted Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of November, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
'cessors, give and grant unto us, the said Scipio Brook and Charles
Thompson, Her special licence that we, the said Scipio Brook and
Charles Thompson, our executors, administrators, and assigns, or such
others as we, the said Scipio Brook and Charles Thompson, our exe-
cutors, 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 we, the
said Scipio Brook and Charles Thompson, our executors or adminis-
trators, by an instrument in writing under our, 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 we, the said Scipio Brook and Charles
Thompson, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described

page_text: This Drawing represents so much of an end elevation of an ordinary
loom as is necessary to shew the application of our Invention thereto.
A is the lever which is hinged upon a stud B fixed in the loom end
frame; one end of this lever carries a friction, roller C, which enters
a cam groove formed in a plate D fixed on a crank shaft E. The other
end of the said lever extends under the lathe or lay F, and is in contact
with a friction roller G mounted upon a bracket or lever-fixed to the
stop rod H, to which is attached a finger or lever I, which enters a loop
fixed on the swell J, by means of which it operates thereon. K is a
catch lever hinged to the loom end, and attached to which is a cord or
chain L passing under the pulley M, and is attached to the strap guide
lever which holds the said catch clear of the notch N in the cam plate or
other plate fixed on the crank shaft when the loom is running, but as
soon as the loom is knocked off the catch falls into the notch and
prevents the loom from running or being run the reverse way. It will
now be easily seen that the cam being properly formed and fixed on the
shaft in suitable position so as to act upon the lever at proper times the
swell must necessarily be operated upon accordingly, and thus only
allow it to press upon the shuttle at the time of its being required to
remain stationery in the box. By this Invention less power is required

page_text: to pick the shuttle, and there is more certainty of its being sent properly
into the other box.
Having thus described the nature of our said Invention, and shewn by
the Drawings how the same is to be or may be performed, we would
have it understood that we do not confine ourselves to the precise details
of arrangement of the parts as hercin set forth; but what we claim
as of our Invention is, the application and use of a lever and cam so
arranged and operated as to act upon the swell of the shuttle box in
manner and for the purpose substantially as described.
In witness whereof, we, the said Scipio Brook and Charles
Thompson, have hereunto set our hands and seals, this Twenty-
second day of May, in the year of our Lord One thousand eight
hundred and sixty-nine.
CHARLES THOMPSON. (L.S.)
