Year: 1864

page_text: LETTERS PATENT to George Hodgson, of Bradford, in the County of
York, Machine Maker, and Alexander Hennah Martin, of Buttershaw
Mills, near Bradford, aforesaid, Mechanic, for the Invention of
"IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED WHEN GIVING MOTION TO:
ROTARY SHUTTLE BOXES OF LOOMS."
Sealed the 28th October 1864, and dated the 6th May 1864.
PROVISIONAL SPECIFICATION left by the said George Hodgson and
Alexander Hennah Martin, at the Office of the Commissioners of Patents,
with their Petition, on the 6th May 1864.
We, GEORGE HODGSON, of Bradford, in the County of York, Machine
Maker, and ALEXANDER HENNAH MARTIN, of Buttershaw Mills, near Bradford,
aforesaid Mechanic, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED WHEN GIVING MOTION TO
ROTARY SHUTTLE BOXES OF LOOMS," to be as follows:-
The object of the improvements is to give increased steadiness to rotary
shuttle boxes after each change from one shuttle chamber to another, so as to
facilitate the obtaining greater speed in the working of looms having such
shuttle boxes. For this purpose we apply stoppers in connection with the
means for effecting the partial rotation of the series of shuttle chambers to
check or stop the momentum produced on the series of chambers by the motion
imparted to them. These stoppers may have a tendency to be out of action
with the box by slight springs or otherwise, so as to admit of the boxes being

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HODGSON, of Bradford, in the County of York, Machine Maker, and
ALEXANDER HENNAH MARTIN, of Buttershaw, Mills near Bradford, aforesaid,
Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of May, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said George Hodgson and Alexander Hennah Martin, Her special
licence that we, the said George Hodgson and Alexander Hennah Martin, our
executors, administrators, and assigns, or such others as we, the said George
Hodgson and Alexander Hennaḥ Martin, our 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 MEANS OR APPARATUS EMPLOYED. WHEN GIVING MOTION TO
ROTARY SHUTTLE BOXES OF LOOMS," upon the condition (amongst others) that
we, the said George Hodgson and Alexander Hennah Martin, our executors
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 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 George Hodgson, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the follow-
ing statement thereof, that is to say :-
The object of the improvements is to give increased steadiness to rotary
sbuttle boxes after each change from one shuttle chamber to another, so as to
t

page_text: facilitate the obtaining greater speed in the working of looms having such
shuttle boxes. For this purpose we apply stoppers in connection with the
means for effecting the partial rotation of the series of shuttle chambers to
check or stop the momentum produced on the series of chambers by the motion
imparted to them. These stoppers may have a tendency to be out of action
with the box by slight springs or otherwise, so as to admit of the boxes being
freely turned by hand when required, and they are brought into action by the
means employed to give rotary motion to the series of cliambers.
But that the Invention may be better understood, we will by the aid of
the accompanying Drawings proceed to describe means pursued by us.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an end view; and Figure 2 a front view of parts of a loom
arranged according to our Invention; Figure 3 shows another end view with
some of the parts in a different position to that indicated by Figure 1. In
each of these views the same letters indicate corresponding parts.
a, a, indicates part of the framing supported by the batten, for carrying
series of rotary shuttle chambers or boxes b, which are affixed to a tube c, so as
to revolve on the fixed axis c¹; d; d, are hooked rods, the hooked ends d' of
which in order to give motion to the boxes in the order desired act upon the
pins e projecting from the plate e', which is affixed to the tube c, all which is
similar to what is ordinarily practised; f, f, are short levers, cach of which is
supported and turns upon a pin f projecting from part of the framing a,
whilst the lower end thereof is acted upon by a spring with a tendency to.
draw its upper end towards the rod d. Each of these rods d is formed to
admit of the upper ends of a lever f being drawn by the spring f' out of the
way of the studs e in the plate e' in order that series of shuttle chambers or
boxes may be caused to revolve on the axis ct by hand, or until by the
action of the hooked end d' of either of those rods upon one of the studs
e a partial rotation has been given to the series of boxes to effect a change
from one box or shuttle chamber to the next, and then the part d² of the
rod d which has thus acted operates upon the end of a lever f to move it
under a pin e, when such lever acts as indicated to prevent the further rota-
tion of the box in that direction until that rod d is again raised as is indicated
by Figure 3.
Figure 4, shows a modification of the improvements. In this case the
upper parts d³ of each of such rods d is inclined in such manner that when
one of the hooked ends d has acted upon a stud e, to cause a partial rotation
of the series of boxes, and brought a fresh box in a line with the lay, such

page_text: inclined part d³ comes between a stud g, fixed in the framing a and one of the
studs e to hold the series of boxes steadily. When the rods d are both raised
above the studs e, as indicated by one of them, the series of boxes is free to be
caused to rotate by hand or otherwise.
By these means greater steadiness is obtained in working rotary shuttle
boxes to admit of greater speed being employed in giving motion to the
looms.
Having thus described our improvements 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. steadiness of
action when giving motion to rotary shuttle boxes of looms, substantially as
explained.
In witness whereof, I, the said George Hodgson, have hereunto set my
hand and seal, this Twenty-eighth day of October, in the year of our
Lord One thousand eight hundred and sixty-four.
GEORGE HODGSON. (L.S.)
