Blackburn, in the County of Lancaster, Machine Makers, for the
Invention of "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING, AND IN
Sealed the 30th September 1858, and dated the 19th April 1858.
PROVISIONAL SPECIFICATION left by the said William Bullough and
Joseph Harrison at the Office of the Commissioners of Patents, with
their Petition, on the 19th April 1858.
We, WILLIAM BULLOUGH and JOSEPH HARRISON, both of Blackburn, in the
County of Lancaster, Machine Makers, do hereby declare the nature of the
said Invention for "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING, AND IN
MACHINERY FOR WINDING THE CORD USED IN THE MANUFACTURE OF WEAVERS
HEALDS," to be as follows:-
Our Invention is applicable to those looms in which a box containing two
or more shuttles is employed, and consists in an improved combination of
machinery for moving the box, so as to bring either shuttle when required in
a line with the shuttle race. A tappet fixed to the tappet shaft or other con-
venient part of the loom gives a vibrating motion to a lever, to which is hinged
a catch taking into a ratchet wheel; to this ratchet wheel is fixed a cam with
elevations corresponding to the number of shuttles in the box; this cam acts
on a lever in connection with the shuttle box. The catch of the ratchet wheel
may be in connection with a jacquard or other apparatus, by which it is
brought into action when required. The catch of the ratchet wheel may in
some cases be worked direct from the jacquard or other apparatus for producing
the required pattern.

Patent, bearing date the Nineteenth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said William Bullough and Joseph Harrison, Her special
licence that we, the said William Bullough and Joseph Harrison, our
executors, administrators, and assigns, or such others as we, the said William
Bullough and Joseph Harrison, 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
"CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING, AND IN MACHINERY FOR WINDING
THE CORD USED IN THE MANUFACTURE OF WEAVERS HEALDS," upon the condition
(amongst others) that we, the said William Bullough and Joseph Harrison,
our executors or administrators, by an instrument in writing under our, or
their, or one of our or 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 William Bullough and Joseph
Harrison, do hereby declare the nature of our said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say) :-
Our Invention of improvements in looms for weaving is applicable to those
looms in which a box containing two or more shuttles is employed, and it con-
sists in certain improved combinations of machinery for moving the box
containing the shuttles, so as to bring either shuttle when required in a line
with the shuttle race.
Our improvements in machinery for winding the cord used in manufacturing
weavers' healds consists in making the spindles of such machines to fit both
the bobbins and pirns used in the machines for knitting or manufacturing
healds; also in making the shaping rail of such machines to move from one
level to another, so as to wind the cord either on bobbins or pirns.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the means pursued by us,
reference being had to the accompanying Sheet of Drawings, and to the
figures and letters marked thereon.
Fig. 1 is an elevation, partly in section, of a loom to which our improve-
ments are applied. a is the crank shaft; b, the tappet shaft; c, the lay
bottom; and d, the drop box containing, in this instance, three compartments
for shuttles. To the tappet shaft 6 is fixed a tappet 6'; this tappet acts on a
bowl projecting from the link e, one end of which is forked, and fits on the
tappet shaft, and the other end is jointed to the lever f, which vibrates on
the fixed stud f; to the upper end of the lever f is hinged the catch g; the
weighted end of this catch is connected to a jacquard or other suitable
apparatus by the cord g¹; the catch g takes into the ratchet wheel h, which
is cast with or fixed to the cam or tappet plate h¹; this tappet plate may be
made with segmental depressors and elevators similar to those known as
Woodcroft's patent segment tappets; it is made with twelve elevators and.
depressors of three different distances from the centre, corresponding to the
number of teeth in the ratchet wheel, and to the number of compartments
in the drop box d. When the shuttle box has a greater or less number of
compartments, the tappet plate h¹ must have a corresponding number of
elevators and depressors. The tappet plate h¹ acts on a bowl projecting from
the link i, one end of which is forked, and is supported by the boss of the
tappet plate, and the other end is jointed to the lever j fixed on the shaft j',
to which is also fixed the lever ; the rod d¹ is connected above to the drop.
box d, and below it is provided with a stud bearing on the lever 1, the
extremity of which is connected to the spring j³.
The Drawing represents the various parts in the positions they occupy

page_text: when the drop box is down; that is to say, when the top shuttle is in a
line with the shuttle race the catch 9 is up, and when the loom is set to
work the shuttle in the top compartment of the drop box will continue to be
picked or thrown across the shed until the cord g¹ is raised by the jacquard
or other apparatus to which it is connected; when the weighted end of the
catch 9 is raised, the other end comes on the ratchet wheel h, as shewn in
dotted lines in Fig. 1, and when the tappet 6' acts on the link e, the catch g
turns the ratchet wheel h round one-twelfth of a revolution, thereby moving
the tappet plate h', which acting on the link i moves the levers j and j³, so as
to raise the drop box. The drop box may be raised either one or two lifts.
according to the shape of the tappet plate. The springs assists in raising
the drop box, which descends by its own gravity. As soon as the drop box
has been raised or lowered, the weighted end of the catch a drops into the
position shewn by full lines in the Drawing, thereby lifting the other end free
from the ratchet wheel, so that the motions of the loom may continue without
changing the position of the drop box until the cord g¹ is again raised, as
before described. It is evident that the number of elevators and depressors
of the tappet plate h, and the order in which they are arranged, may be
varied to suit the pattern required, and that when a great number of shuttles
are required it may be desirable to employ two or more tappet plates similar
to h. When this is the case we prefer to make use of the improved apparatus
shewn in Fig. 2, which represents an elevation, and Fig. 3 a side view, of
a small jacquard, commonly called a "dobby," suitable for acting upon the
cords g of the catches g. To the tappet shaft b is fixed in the usual manner
a crank pin b², which gives motion to the lever k fixed to the shaft k¹; to this
shaft are fixed the levers & supporting the cylinder 1; the upper ends of the
levers are bevelled to act on the lifter m; a chain of perforated lags
marked passes around the cylinder in the usual manner, and the cylinder
is turned one-eighth of a revolution at every revolution of the tappet shaft by
the catches m' taking into the ratchet wheels on the cylinder shaft; the lifter
m is raised when the lever k is drawn down by the bevelled ends of the
levers acting on the ends of the lifter, and the hooks to which the cords g'
are attached are raised by the lifter when selected by the horizontal wires of
the "dobby" in the usual manner.
Fig. 4 is a side elevation of a machine for winding the cord used in the
manufacture of weavers' healds, to which our improvements are applied. n is
a spindle, of which twelve or any convenient number are employed in the
machine. These spindles are supported in the bearings n' and foot-steps n², and
they are turned round by a band from the drum o. The spindles n are made

page_text: of two different diameters, so as to fit both the bobbins p, see Fig. 4, and the
pirns g, shewn in the detached view, Fig. 5. In front of the spindles is the
shaping rail r, over which the cord passes when unwound off the reels s. The
shaping rail r is supported at each end of the machine in uprights r¹, at the
upper end of which are forks into which the shaping rail r is placed when the
cord is being wound on the pirns, as shewn in Fig. 5. The uprights and
shaping rail r are raised and lowered to distribute the cord evenly on the
bobbin or pirn by the excentrics t acting on the levers t¹, to the upper end of
each of which is attached one end of the chains t², the other ends being con-
nected to the uprights r. By thus making the spindles of winding machines
of the requisite diameters to fit either the bobbins or pirns, and the shaping
rail moveable, as described, the same machine may be employed to wind both
the bobbins and the pirns used in machines for manufacturing weavers'
healds.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we wish it to be understood that we do not limit our-
selves to the details set forth, as the same may be modified without departing
from the peculiar character thereof; but what we do claim is,-
First, the improved combination of machinery shewn and described in
reference to Fig. 1, for moving the shuttle box so as to bring each shuttle when
required in a line with the shuttle race.
Secondly, the improved apparatus, shewn and described in reference to
Figs. 2 and 3, for governing the number of picks to be given by each shuttle.
Thirdly, the so constructing the spindles of machines for winding the cord
used in the manufacture of weavers' healds, that both the bobbins and the
pirns used in machinery for knitting or manufacturing healds may fit on
the same spindles, as shewn and described in reference to Figs. 4 and 5.
And, lastly, the making the shaping rail of such winding machines capable
of being moved from one level to another, as described.
In witness whereof, we, the said William Bullough and Joseph
Harrison, have hereunto set our hands and seals, this Sixteenth day
of October, in the year of our Lord One thousand eight hundred and
fifty-eight
