IMPROVEMENTS IN LOOMS FOR WEAVING SPONGE CLOTHS BY POWER."
Year: 1867

page_text: LETTERS PATENT to Daniel Collinge and John Collinge, of Oldham, in
the County of Lancaster, for the Invention of "IMPROVEMENTS IN LOOMS
FOR WEAVING SPONGE CLOTHS BY POWER."
PROVISIONAL SPECIFICATION left by the said Daniel Collinge and John
Collinge at the Office of the Commissioners of Patents, with their
Petition, on the 10th July 1867.
We, DANIEL COLLINGE and JOHN COLLINGE, of Oldham, in the County of
Lancaster, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LOOMS FOR WEAVING SPONGE CLOTHS BY POWER," to be as follows:-
This Invention relates to that description of looms employed for weaving
sponge cloths or similar fabrics in which a continually crossing motion has to
be given to the warp during the process of weaving.
Our improved looms are worked by power, and the healds are divided into
two sections, each composed of a staff having fixed to it a number of strong
wires with eyes at their ends, the eyes of one staff nearly facing the eyes of
the opposite staff. The upper section of the healds moves down and up by
means of tappets, treddles, and springs, and the lower section, which is sup-
ported on a spring rod, moves to and fro horizontally by the action of a lever
having a tongue or projection geared into the grooves of a cam or double
screw fixed to the crank shaft of the loom, or the to-and-fro motion may be

page_text: imparted by any ordinary mechanical contrivance for giving alternate motion.
The healds and warps are moved downwards by one set of tappets, and
upwards by the springs during the process of weaving the open or sponge
part of the fabric, and after the required length for each cloth is woven the
tappets are shifted from the treddles and other tappets placed over them for
obtaining several straight picks for binding the ends of weft at the end of
each cloth. The tappets are fixed to a long boss which can slide on the
tappet shaft, and motion is given to them at the required time by a lever and
rod acting on fork levers having their ends placed in grooves in the boss.
When two lengths of cloths are woven side by side in one piece the weft yarns
are afterwards cut through in the middle by a stationary knife which divides
the piece into two lengths as they advance to the taking-up and winding-on
beams common to power looms.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Daniel Collinge and John Collinge in the Great Seal Patent
Office on the 10th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, DANIEL.
COLLINGE and JOHN COLLINGE, of Oldham, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Tenth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Daniel Collinge and John Collinge, Her special license that we, the said Daniel
Collinge and John Collinge, our executors, administrators, and assigns, or
such others as we, the said Daniel Collinge and John Collinge, 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 LOOKS FOR WEAVING SPONGE
CLOTES BY POWER," upon the condition (amongst others) that we, the said
Daniel Collinge and John Collinge, 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

page_text: 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 Daniel Collinge and John Collinge,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
This Invention relates to that description of looms employed for weaving
sponge cloths or similar fabrics in which a crossing motion has to be given to
the warp during the process of weaving, and our improvements consist in
various mechanical contrivances and arrangements for enabling the said
fabrics to be woven by power.
The manner in which our Invention is to be performed will be clearly
understood by the following particular description thereof, reference being had
to the figures and letters on the accompanying Sheet of Drawings, in which
Figs. 1 and 2 are end and front elevations of one of our improved looms for
weaving sponge cloths or similar fabrics by power, and Fig. 3 a full-sized view
of one of the parts.
a represents the end frames of the loom; b, the crank shaft; c, the driving
and loose pulleys; d, the tappet shaft; and e, the winding-on beam. The
warp threads f pass through three sets of eyes, one set at the ends of strong
wires g fixed to the cross bar h, another set at the ends of strong wires i
fixed to the cross bar k, and the third set attached to cords fastened to the
cross bar m, the cross bars k, m, being fixed to vertical rods working in
guides n, and tied together by tie bars o, p. The cross bar k is connected by
cords q to straps r fixed to the rollers s on the roller shaft t, and its corre-
sponding tie bar o is connected by cords u to the treddles v worked by the
double tappets w on the tappet shaft d. The tie bar p is connected by cords *
to the springs y, and its corresponding cross bar m connected by other cords
to the treddles, worked when required by the tappets a'. The cross bar his
placed in horizontal guides 6' and connected to the top of a blade spring c¹
fixed at the bottom to the cross rail d', and connected by the rod e¹ to one
end of a lever f, the other end of which is provided with a swivel tongue or
projection geared into the grooves of a cam 91, Figs. 1, 2, and 3, fixed to the
crank shaft 6 for giving a to-and-fro motion horizontally to the wires g, but
the said to-and-fro motion may be imparted by any ordinary mechanical con-
trivance for giving alternate motion. The tappets w, a, and also tuppets a³,
are fixed on a long boss h', which can slide on the tappet shaft in order to
change the position of the tappets when required, motion being given to the
boss by means of the lever k', the shaft l', the lever m', the rod n', and the fork

page_text: levers o¹, placed in grooves in the boss h¹. The slay sword, arms, shuttle,
pickers, and picking sticks are of the ordinary construction as used in power
looms, and when the loom is at work for weaving the sponge part of the
fabric the double tappets w depress the treddles v and wires i for making the
shed. The cam g¹ gives horizontal motion to the wires g for giving the
crossing motion, and the strong springs pl act on the roller shaft t to close the
shed for the beat up. After the required length of sponge part for each cloth
is woven the tappets ware shifted from the treddles v, and the tappets a¹
and a are brought over the treddles v and z, so that both the wires i and
cords shall act on the warp for obtaining several straight picks for binding
the ends of weft at the end of each cloth.
When two lengths of cloth are woven side by side in one piece the weft
yarns are cut in the middle by a stationary knife q which divides the piece
into two lengths as they advance to the taking-up and winding-on beam;
or instead of a stationary knife an oscillating or rotary one may be used..
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be under-
stood that we claim the improvements in looms for weaving sponge cloths
by power, as herein described and illustrated in the accompanying Sheet of
Drawings.
In witness whereof, I, the said John Collinge, for and on behalf of
myself and the said Daniel Collinge, have hereunto set my hand and
seal, this Ninth day of January, in the year of our Lord One thousand
eight hundred and sixty-eight.
Signed, sealed, and delivered
by the within-named John
Collinge, in the presence of
