IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1856

page_text: LETTERS PATENT to Robert Edmeston, of the firm of Mess" Edmeston
and Higham, of Bradford, in the County of York, for the Invention of
"IMPROVEMENTS IN LOOMS FOR WEAVING."
Scaled the 31st March 1857, and dated the 2nd October 1856.
PROVISIONAL SPECIFICATION left by the said Robert Edmeston at the
Office of the Commissioners of Patents, with his Petition, on the
2nd October 1856.
I, ROBERT EDMESTON, of the firm of Mess Edmeston and Higham, of
Bradford, in the County of York, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention has for it object improvements in looms for weaving, and
the improvements consist of a combination of apparatus actuated or governed
by the jacquard or pattern surfaces of the loom, in order to move the shuttle
boxes according to the requirement of the particular pattern which is being
woven in the loom. For this purpose, the cam shaft of the loom is caused by
a tappet or cam to act on a lever or instrument in connection with the shuttle
boxes, in such manner that the shuttle boxes are caused to be lifted when the
tappet or cam is by the jacquard or pattern surface allowed to act on the lever
or instrument above mentioned; but when the lever or instrument is moved
out of the way of the cam or tappet the shuttle boxes are not raised by the
rotation of the shaft of the loom. The shuttle boxes are retained from

page_text: descending by a catch acting in the teeth of a ratchet, carried by a lever or
instrument, which lifts the shuttle boxes, and this catch retains the shuttle
boxes from descending to their lowest position (which they have a tendency
to do), excepting when the jacquard or pattern surface of the loom causes the
catch to be removed. By these means the several shuttle boxes of a loom are
brought into and removed out of position, according to the requirement of the
particular pattern which is being woven.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Edmeston in the Great Seal Patent Office on the
2nd April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
EDMESTON, of the firm of Mess" Edmeston. and Higham, of Bradford, in the
County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Robert Edmeston, Her special licence that I, the said Robert
Edmeston, my executors, administrators, and assigns, or such others as
I, the said Robert Edmeston, 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 Edmeston, 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 Robert Edmeston, do hereby declare the
nature of the 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 thereof, that is to say :-
This Invention has for its object improvements in looms for weaving, and

page_text: revolution of the shaft a the pin on the lever 6' will cause the levers 66
and b' to move forward one tooth of the rack on the top of the lever b', which
is a distance equal in extent to the depth of one shuttle box compartment.
Backward movement is prevented by the catch 610 descending into a fresh
notch or recess on the top of the lever b. The cam c revolves without
áctuating its lever until such time as that lever is allowed to be moved
by the spring c, and this is effected when the jacquard pattern surface so
acting on the cord as to slack it, and allow of the bell crank c² giving way
to the power of that spring. For this purpose one end of the crank lever c³
is attached to the cord c', and the other end of the cranked lever c³ passes
through a slot in the lever c; the lever will by the spring c be pressed
and caused to move on its centre c³ towards the cam c, so that on the next
revolution of the cam shaft a the tappet c will act on the incline.c, carried
by the lever c, in such manner as to raise the lever c, and consequently the
catch 610 (to which it is affixed,) by which the lever 6' will be allowed to travel
backwards to the extent of one of the teeth of the rack, when the catch 60
will descend again by the action of the spring 6*; after which the lever c will
be moved out of the way of the tappet c by the tightening of the cords c¹,
and will so remain until the pattern surface again causes the cord c¹ to be
slackened.
Having thus described the nature of my said Invention, and the manner. of
performing the same, I would have it understood that I make no claim to any
of the parts separately, nor do I confine myself to the details; but what I
claim is, the mode herein described of combining the mechanical parts for
acting on the shuttle boxes of power looms.
In witness whereof, I, the said Robert Edmeston, have hereunto set my
hand and seal, this Thirty-first day of March, in the year of our Lord
One thousand eight hundred and fifty-seven.
