Year: 1869

page_text: LETTERS PATENT to George Hodgson, of Bradford, in the County of
York, Loom Manufacturer, Henry Bottomley, of Low Moor, near
the said Bradford, Manufacturer, and Ezra Cockroft, of Odsall
Moor, also near the said Bradford, Overlooker, for the Invention of
"IMPROVEMENTS IN LOOMS FOR WEAVING."
Scaled the 21st September 1869, and dated the 27th March 1869.
PROVISIONAL SPECIFICATION left by the said George Hodgson, Henry
Bottomley, and Ezra Cockroft at the Office of the Commissioners of
Patents, with their Petition, on the 27th March 1869.
We, GEORGE HODGSON, of Bradford, in the County of York, Loom
Manufacturer, HENRY BOTTOMLEY, of Low Moor, near the said Bradford,
Manufacturer, and EZRA COCKROFT, of Odsall Moor, also near the said
Bradford, Overlooker, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The improvements relate, first, to means for effecting variations in the
order of "picking." Upon the tappet or other suitable shaft we apply a
small bevil tooth wheel of, say, 30 teeth to gear into another of, say,

page_text: 60 teeth upon another axis, upon which is also applied a tappet to work
The square
in a square casting or frame, or between suitable arms.
casting or frame is applied on a square or other suitable rod to slide in a
pair of castings, arms, or guides affixed to a rod which is capable of
endway motion, and which carries forks or other arms to slide or move
the cones or arms of the picker shafts into or out of the way of the
picking tappets according to the order of picking for the time desired.
The improvements relate, secondly, to means for actuating, vibrating,.
or rocking shuttle boxes to vary the order of selection of shuttle. The
boxes at each end of the batten are affixed to a common axis, which
is supported to rock in bearings carried by the batten or going parts,
and has applied to it an arm, which, by connecting rod and pin joints
is attached to one end of an elastic-ended lever, the other end of which
is by connecting rod and pin joints connected to a frame or fork
applied to a rocking arm or lever with means of adjustment as to
position for variations of distance of motion obtained. This frame or
fork receives and is actuated by a cam or tappet on the tappet or other
suitable shaft. Each arm of the clastic-ended lever referred to is formed
in two parts hinged together with the part of one arm or one end of the
lever capable of turning on its hinge joint in the opposite direction to
that of the other. Each arm or end of the lever is held from turning on
its hinge joint with a certain degree of rigidity against a stop to each
part by springs yet so as to yield in the event of the shuttle sticking part
in the box and part in the shed or other stoppage. By the use of cards
or pattern surface for actuating the tappet increased variation in the
weaving may be effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Hodgson, Henry Bottomley, and Ezra
Cockroft in the Great Seal Patent Office on the 27th September
1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HODGSON, of Bradford, in the County of York, Loom Manufacturer,
HENRY BOTTOMLEY, of Low Moor, near the said Bradford, Manufacturer,
and EZRA COCKROFT, of Odsall Moor, also near the said Bradford,
Overlooker, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of March, in the
year of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Ilerself, IIer heirs and successors,
give and grant unto us, the said George Hodgson, Henry Bottomley, and
Ezra Cockroft, Her special licence that we, the said George Hodgson,
Henry Bottomley, and Ezra Cockroft, our executors, administrators, and
assigns, or such others as we, the said George Hodgson, Henry Bottomley,
and Ezra Cockroft, our exccutors, 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 George Hodgson, Henry Bottomley,
and Ezra Cockroft, our exccutors or administrators, by an instrument in
writing under our or their hands and seals, or under the hand and seal
of one of us or them, should particularly describe and ascertain the
naturo 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 George Hodgson, on behalf of
myself and the said Henry Bottomley and Ezra Cockroft, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say :-
The improvements relate to an adaptation or combination of means
for effecting variations in the order of selection of shuttles in looms for
weaving.
The boxes at each end of the batten are affixed to a common axis,
which is supported to rock in bearings carried by the batten or going
parts, and has applied to it an arm, which by connecting rod and pin
joints is attached to one end of an elastic ended lever, the other end of
which is by connecting rod and pin joints connected to a frame or fork
applied to a rocking arm or lever with means of adjustment as to
position for variations of distance of motion obtained. This frame or
fork receives and is actuated by a cam or tappet on the tappet or other

page_text: portion of one end of the front of a loom; and Figure 3, a plan view
of parts separately to illustrate one portion of the combined Invention.
a, a, in each of these views indicates the framing of the loom; h, the
main or crank shaft; and b, the cam or tappet shaft; i shows one of the
vibratory shuttle boxes, each of which is formed with two shuttle
chambers i, i, and both boxes are affixed to a common axis ³, so as
to be capable of rocking with that axis. The axis is supported for
this purpose in bearings carried by the batten, and it has applied to it
the arm j, the outer end of which is, by a connecting rod k, connected to
one end of the lever 1, which is supported to turn upon a fixed stud or
projection, and at its other end is connected by the connecting rod
and pin joints to the frame n, or it may be a fork. This frame n is
formed with arms n', ', which are capable of sliding in the stationary
guides a", a³, as motion is given to the frame by the rotation within it
of the cam or tappet o on the cam or tappet shaft b. It will be seen.
that each arm of the lever is formed elastic by being formed in two
parts capable of turning each in one direction, but each in the opposite

page_text: direction to that of the other on pins P. The parts of each end of the
lever are held to act with a certain degree of rigidity by means of the
springs drawing them against the parts l', yet so as to admit of their
yielding in the event of the shuttle sticking or otherwise. By the use
of cards or pattern surface for actuating the tappet increased variation in
the weaving may be effected.
Figure 4 shews by a back view of some of the parts of a loom
another portion of the combined Invention applied; Figure 5 shows a
plan view, and Figure 6 a sectional view of some of these parts of the
apparatus separately. In cach of the views the same letters are
employed to indicate corresponding parts.
a, a, indicates the framing; b, the tappet shaft, upon which is applied
the small bevilled toothed wheel c of, say, 30 teeth, which gear into the
teeth of the bevilled tooth wheel d of, say, 60 teeth. This wheel dis
affixed upon one end of a short shaft d', which is supported so as to be
capable of freely revolving in a bearing provided for it in the cross
framing a. At the lower end of this shaft d' is affixed the tappet e in
position as it revolves to actuate the frame faffixed to the rod 9, which
is supported in a pair of castings, arms, or guides a², a², so as to be
capable of endway motion therein. This rod y carries forks g', g', which
embrace the necks of the respective tappets to move them out of the
way of the picking cones; or these forks might act as heretofore to slide
the cones into or out of the way of the picking tappets.
Having thus described our Invention, and means which we adopt in
carrying the same into effect, we would have it understood that what
we claim is, the adaptation or combination of means for effecting
variations in the order of selection of shuttles in looms for weaving,
substantially as described.
In witness whereof, I, the said George Hodgson, have hereunto set
my hand and seal, this Twenty-fifth day of September, in the
vear of our Lord One thousand eight hundred and sixty-nine.
