APPARATUS FOR GIVING TENSION TO THE WARP Looms
Year: 1824

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HARWOOD HORROCKS, of Stockport, in the County of Chester, Cotton Manu-
facturer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifteenth day of June, in the fifth year of His reign, did
for Himself, His heirs and successors, give and grant unto me, the said
William Harwood Horrocks, His especial licence, that I, the said William
Harwood Horrocks, my exors, admors, and assigns, or such others as I, the
said William Harwood Horrocks, my exors, admors, or assigns, should at any
time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "APPARATUS FOR GIVING TENSION TO THE WARP
Looms;" in which said Letters Patent there is contained a proviso obliging
me, the said William Harwood Horrocks, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the nature of my
said Invention, and in what manner the same is to be performed, and to
cause the same to be inrolled in His said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Harwood Horrocks, do hereby declare the nature of my said Inven-
tion to consist in the application of friction by means of springs acting against

page_text: the warp roll to give tension to the warp instead of such weights as are now in
use for the said purpose. And in further compliance with the said proviso,
I, the said William Harwood Horrocks, do hereby further declare the
manner in which I perform and construct my said Invention by the following
description thereof, reference being had to the Drawings annexed, and the
Figures marked thereon, that is to say :-
DESCRIPTION OF THE DRAWING.
Fig. 1 represents a warp roll, supposed to be in its proper situation in
a loom, and as my said apparatus is only connected with one end of the warp
roll, I have not thought it necessary to represent any parts of the loom not
immediately connected with it. A, A, is a cast-iron collar fixed on to the end
B of the warp roll, and turned down to a small smaller size in the centre to
receive C, which is a clip or clam, more particularly explained in the descrip-
tion of the other Figures. It will be seen by this Figure that the two sides of
the collar A, A, will keep the clip or clam C from moving laterally in any
direction out of its proper place.
Fig. 2 represents the clip or clam C, and is a section of the small part or neck
of the collar A, such parts as would appear behind the clip or clam being
omitted, in order not to confuse the Figure, and thus the better to shew the
action of the clip or clam. This clam, for such I will call it, should be made
of wrought iron. D is a screw which, being turned one way or the other,
either draws the two sides of the clam closer together or allows them to expand
farther apart. E is a similar screw below the collar, and is used for a similar
purpose. Now it will be seen that according to the strength of the iron of
which the clam is made, and the tightening of the screws, any required
pressure or nip may be given to the neck of the collar, and according to the
quantum of pressure or nip so will friction be created on the neck of the collar,
and the warp roll restrained from yielding to the action of the warp caused by
the stroke of the lay.
Fig. 8 is an end view of my said apparatus. The dotted lines shew the
manner in which the clam clasps the small part or neck of the collar. There
is no occasion to have the leg F of the clam so long as the leg G, for if it be
long enough to admit of taking the screw, as represented in this Figure, it will
be sufficient, and the leg G may be any length below the screw E, to suit the
framework of the loom. In this Figure it is represented as screwed to the
floor at H, which mode of securing it answers perfectly well.
Now, such an apparatus as herein-before described for the purpose aforesaid,
being, to the best of my knowledge and belief, entirely new, and never before

page_text: used in these Kingdoms, I do hereby declare this to be my Specification of the
same, and I do verily believe this my said Specification doth comply in all
respects, fully and without reserve or disguise, with the proviso in my said
herein-before in part recited Letters Patent contained, wherefore I do hereby
claim to maintain exclusive right and privilege to my said Invention.
In witness whereof, I, the said William Harwood Horrocks, have here-
unto set my hand and seal, this Sixth day of December, in the year of
our Lord One thousand eight hundred and twenty-four.
