IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1870

page_text: LETTERS PATENT to Riley Livesey Haworth, of Blackburn, in the
County of Lancaster, Power Loom Weaver, for the Invention
of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 17th March 1871, and dated the 20th September 1870.
PROVISIONAL SPECIFICATION left by the said Riley Livesey Haworth
at the Office of the Commissioners of Patents, with his Petition,
on the 20th September 1870.
I, RILEY LIVESEY HAWORTH, of Blackburn, in the County of Lan-
caster, Power Loom Weaver, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates to improved apparatus for retarding the shuttle
on its entrance to the shuttle box so as to prevent or greatly reduce
damage to the pickers, and to dispense with the check straps. At the
back of the shuttle box I place on a stud or pin two "swells," one
of which is provided with a finger; on or against the latter a spring
rests. On the entrance of the shuttle to the box the swell nearest is
forced back (by the impetus of the shuttle); the spring and finger now

page_text: force the second swell inwards, and against which the shuttle bears, and
by which its motion is arrested. The spring set in motion by the
finger at once recovers its original position, so that the shuttle is
released from pressure for the return pick.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Riley Livesey Haworth in the Great Seal Patent
Office on the 20th March 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RILEY
LIVESEY HAWORTH, of Blackburn, in the County of Lancaster, Power
Loom Weaver, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of September, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Riley Livesey Haworth, Her special licence
that I, the said Riley Livesey Haworth, my executors, administrators,
and assigns, or such others as I, the said Riley Livesey Haworth, 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 " IMPROVEMENTS
IN LOOMS FOR WEAVING," upon the condition (amongst others) that I, the
said Riley Livesey Haworth, my executors or administrators, by an
instrument in writing under me, 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 Riley Livesey Haworth, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-

page_text: This Invention relates to improved apparatus for retarding the shuttle
on its entrance to the shuttle box, so as to prevent or greatly reduce
damage to the pickers, and to dispense with the check straps. At the
back of the shuttle box I place on a stud or pin two "swells," one of
which is provided with a finger; on or against the latter a spring rests.
On the entrance of the shuttle to the box the swell nearest is forced
back (by the impetus of the shuttle); the spring and finger now force
the second swell inwards, and against which the shuttle bears, and by
which its motion is arrested. The spring set in motion operated by the
shuttle at once recovers its original position, so that the shuttle is
released from pressure for the return pick.
Such being the nature and object of this my Invention, I will now
proceed to describe the same in detail, and in order that the same may
be fully understood I have hereunto annexed a Sheet of Drawings, and
have marked the same with figures and letters of reference, the same
letter referring to the same part in the various views or Figures.
Figure 1 is sectional elevation of part of shuttle box with my improve-
ments attached; Figure 2 is a plan view of the same.
A is a stud or pin on which the “swells” B, B¹, work. The swell B¹.
is hinged at a, a; C is a finger, on or against which the spring E rests.
On the entrance of the shuttle F to the shuttle box G, the swell B¹
is forced by the impetus of the shuttle) back or towards the finger C,
forcing the swell B inwards, the latter binding or pressing on the rear
end of the shuttle, retarding the same and arresting its motion, the
spring E and swell B' at once returning to their original position on the
return pick to the opposite box, which is provided with apparatus same
as that above described.
Figure 4 is plan view, and Figure 3 sectional elevation of similar
apparatus, the fàce or projecting part of swell B' sliding in a groove of
box (by impetus of shuttle on its entrance thereto), and by means
of the incline H forcing outwards the finger C, which in turn forces
or moves inwards and against the shuttle the swell B.
Figures 5, 6, 7 and 8 are detail or detached-views of the parts above
described; J is a spinal spring for bringing to its original position the
swell B' ready for the next entrance of the shuttle to the box.
It will be seen that the apparatus is compound in its action, that is,
the resistance of the first swell or swell nearest the entrance to the box
being overcome (by impetus of the shuttle) the surplus power is by the

page_text: first swell transmitted to the second one, so that the apparatus is
self-adjusting. The greater velocity at which the shuttle enters the box,
so will a proportionate greater power of resistance on the part of the
second swell be exerted to retard and overcome force of motion of said
shuttle.
Having thus fully described the nature and particulars of this my said
Invention, together with the manner in which the same is to be or may
be performed or carried into practical effect, I would have it distinctly
understood that I claim as my Invention, the construction and com-
bination of the two or compound acting swells, in the manner and
for the purpose herein described and illustrated.
In witness whereof, I, the said Riley Liversey Haworth, have here-
unto set my hand and seal, this Seventeenth day of March,
in the year of our Lord One thousand eight hundred and
seventy-one.
