CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1863

page_text: LETTERS PATENT to William Hampson, the younger, of Dukinfield, in
the County of Chester, Overlooker, for the Invention of "CERTAIN
IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 8th April 1864, and dated the 17th October 1863.
PROVISIONAL SPECIFICATION left by the said William Hampson at
the Office of the Commissioners of Patents, with his Petition, on the
17th October 1863.
I, WILLIAM HAMPSON, the younger, of Dukinfield, in the County of
Chester, Overlooker, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
My improvements are designed for the purpose of easing or checking the
blow or concussion of the shuttle against the picker of the ordinary power
loom during the operation of weaving, such improvements consisting in the
novel employment and use of a flattened piece or strip of metal so formed and
constructed that its opposite ends embracing the picker shall slide or move
upon the loom spindle, whilst its middle, or that portion between the ends,
slides through a slot in a friction box secured conveniently in the shuttle box
below the spindle, the sliding motion taking place every time the shuttle is
received by the picker in the shuttle box. The said friction box is supplied
with a set screw and lock nut for the purpose of exerting or giving any
desired amount of friction to the afore-mentioned sliding piece or strip of
metal; by this means I gradually diminish or ease the blow of the shuttle

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HAMPSON, the younger, of Dukinfield, in the County of Chester, Overlooker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of October, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Hampson, Her special license that I, the said William
Hampson, my executors, administrators, and assigns, or such others as I,
the said William Hampson, my 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," upon the condition
(amongst others) that I, the said William Hampson, my executors or
administrators, by an instrument in writing under my, or their, or one of
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 I, the said William Hampson, 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 fol-
lowing statement and accompanying Drawings (that is to say) :-
:-
My improvements are designed for the purpose of easing or checking the
blow or concussion of the shuttle against the picker of the ordinary power
loom during the operation of weaving, such improvement consisting in the
novel employment and use of a flattened piece or strip of metal so formed and
constructed that its opposite ends embracing the picker shall slide or move
upon the loom spindle, whilst its middle, or the portion between the ends,

page_text: slides through a slot in the friction box secured conveniently in the shuttle box
below the spindle, the sliding motion taking place every time the shuttle is
received by the picker in the shuttle box. The said box is supplied with a
set screw and lock nut for the purpose of exerting or giving any desired
amount of friction to the aforesaid sliding piece or strip of metal; by this
means I gradually diminish or ease the blow of the shuttle against the picker,
thereby causing the pickers to be more durable, and also dispensing with the
check straps now in use.
In order that the Invention may be better understood and explained in detail
I have hereunto attached a Sheet of Drawings, made upon a scale of about
six inches to the foot, similar letters of reference being marked upon cor-
responding parts.
Fig. 1 represents a front view of the shuttle box of a loom having my
improvements attached; Fig. 2 is a plan view of the same, and Fig. 3 repre-
sents a vertical sectional view of that portion designed to check the concussion
of the picker.
In Fig. 1, a, a, is the shuttle box, and 6 the picker running on the spindle c
and coming into contact at each limit or termination with the metallic band
or guard d, which also slides slightly on the spindle as it is struck by the
pickers. The amount of resistance offered by the said guard to the picker is
regulated by means of the plate e, which is pressed against the leather washer
or strip f, and exerts pressure on the metallic guard d by means of the nut
and screw g, the said parts being supported by the adjustable piece h.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim the improved arrangement and construction of appa-
ratus for diminishing and gradually checking the concussion of the picker in
power looms, which has been herein-before described, set forth, and fully
illustrated in the Drawings attached.
In witness whereof, I, the said William Hampson, have hereunto set
my hand and seal, this Fourteenth day of April, in the year of our
Lord One thousand eight hundred and sixty-four.
WILLIAM HAMPSON. (L.S.)
