Brandon and Morgan-Brown, Engineers and Patent Agents, of
38, Southampton Buildings, London, and 13, Rue Gaillon, Paris,
for the Invention of "IMPROVEMENTS IN LOOM SHUTTLES AND SHUTTLE
SPINDLES."-A communication from abroad by Edgar Mantleburt

of America
PROVISIONAL SPECIFICATION left by the said William Morgan-Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 24th November 1875.
I, WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-
Brown, Engineers and Patent Agents, of 38, Southampton Buildings,
London, and 13, Rue Gaillon, Paris, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LOOM SHUTTLES AND SHUTTLE
SPINDLES," to be as follows:-
This Invention of improvements in loom shuttles and shuttle spindles
has for its object to produce a spindle for loom shuttles, which is so

page_text: constructed as to admit of the cop being readily slipped upon it, and
be securely held on the same during the throw of the shuttle across the
loom.
A great difficulty in the operation of loom shuttles and spindles con-
sists in their inability to hold and firmly retain the cop owing to the
violent concussion to which the shuttle is subjected at each end of the
throw from the picker staff. In consequence of this difficulty a great
waste of the thread and destruction of the cop is experienced. This
difficulty is believed to be fully obviated by the present Invention.
The Invention consists firstly in attaching the spindle to its head,
which is pivotted to the shuttle by means of a coiled spring in such a
manner as to allow the spindle to yield in the direction of its length as
the shuttle reaches its limit of throw, and thus avoid the ill effects of
the concussion in its action on the cop.
The Invention further consists in the attachment to the ends of the
shuttle of a yielding metal point also for the purpose of obviating the
effects of the concussion.
The Invention further consists in enlarging the ends of the slot in
the spindle and making the sides of the latter at and near each end of
the slot much thinner than the main portion of the sides of the
spindles, so as to admit of the cop being readily slipped upon the
spindle and be securely held in position during the throw of the
shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Morgan-Brown in the Great Seal Patent
Office on the 29th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown,
Engineers and Patent Agents, of 38, Southampton Buildings, London,
and 13, Rue Gaillon, Paris, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of November, in the
year of our Lord One thousand eight hundred and seventy-five, in

page_text: the thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Morgan-Brown, Her
special license that I, the said William Morgan-Brown, my executors,
administrators, and assigns, or such others as I, the said William
Morgan-Brown, 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 LOOM SHUTTLES AND SHUTTLE SPINDLES,"
(a communication to me from abroad by Edgar Mantleburt Stevens, of
Boston, County of Suffolk, Massachusetts, United States of America,)
upon the condition (amongst others) that I, the said William Morgan-
Brown, 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 Morgan-Brown, 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 following statement thereof, that is to say :-
This Invention of improvements in loom shuttles and shuttle spindles
has for its object to produce a spindle for loom shuttles, which is so
constructed as to admit of the cop being readily slipped upon it and
be securely held on the same during the throw of the shuttle across the
loom.
A great difficulty in the operation of loom shuttles and spindles
consists in their inability to hold and firmly retain the cop, owing to
the violent concussion to which the shuttle is subjected at each end
of the throw from the picker staff. In consequence of this difficulty
a great waste of the thread and destruction of the cop is experienced.
This difficulty is believed to be fully obviated by the present In-
vention.
The Invention consists firstly in attaching the spindle to its head,
which is pivoted to the shuttle by means of a coiled spring, in such a

page_text: manner as to allow the spindle to yield in the direction of its length as
the shuttle reaches its limit of throw, and thus avoid the ill effects of
the concussion in its action on the cop.
The Invention further consists in the attachment to the ends of the
shuttle of a yielding metal point, also for the purpose of obviating the
effects of the concussion.
The Invention further consists in enlarging the ends of the slot in
the spindle, and making the sides of the latter at and near each end of
the slot much thinner than the main portion of the sides of the
spindle, so as to admit of the cop being readily slipped upon the
spindle and be securely held in position during the throw of the
shuttle.
represents
embodying my Invention.
Figure 2 represents the elastic metal point and its mode of attachment
to the shuttle.
Figure 3 represents my improved spindle head having a solid spindle
attached to it.
And Figure 4 is a view of my improved slotted spindle.
My improvements are such as to enable them to be readily adapted to
the common form of shuttles in use, of which Figure 1 represents a
longitudinal vertical section. f is the spindle attached to the head c,
which is held in a closed position by the spring 6 in the usual manner.
On the under side of the spindle head is a projecting lug or stop d,
which extends downwards and abuts against a portion of the solid part
of the shuttle e, as shown in Figure 1. The inner end of the spindle is
of somewhat smaller diameter than the main portion, and is fitted to
slide freely in the head c. It is formed with a shoulder at o which
abuts against the front portion of the head c. Within a slot in the
head c is a coiled spring 8 which surrounds that portion of the spindle
within the slot, and admits of the spindle yielding in the direction of
its length. In the end of the spindle is secured the yielding point h;
this consists of a cylindrical piece of steel or other hard metal having a
cavity in its inner end. In this cavity is fitted a cylindrical piece of

page_text: rubber or equivalent elastic material, and projecting somewhat from the
end of the metal holder h bears against the bottom of a cavity formed
in the head of the shuttle, as shown in Figure 1. The cylindrical
metallic piece h is fitted snugly within a shell or holder g, and is pro-
vided with a rim or shoulder on its inner end which abuts against the
end of the inner cylindrical portion of the shell g, so that its outward
movement is limited, while a pressure on its outer end will cause it to
yield by the compression of the rubber spring. The outer portion of
the shell or holder g conforms to the curved end of the shuttle, as shown
in Figure 1. The inner cylindrical portion of the shell g¹ may be pro-
vided on its surface with slight projections or teeth in such a manner as
to cause it to be securely held when inserted in the end of the shuttle.
The yielding points h may be inserted in one or both ends of the shuttle
as found desirable. When the spring in the spindle head is used to
admit of the spindle yielding in one direction the spring point h may
be inserted in the end of the shuttle which will give it a yielding effect
in the opposite direction.
It will be seen that the elastic point may be readily adapted to shuttles
now in use of the ordinary construction.
The ends of the slot k are

of the spindle 7, 1, and m, m, near the ends of the slot are made thinner
than that portion of the sides between these two parts. By this con-
struction a peculiar degree of elasticity is imparted to the sides of the
spindle, so as to allow them to yield to a slight pressure to receive the
cop, while the thickness of the sides extending through the greater
portion of the slot serves to maintain a steadiness of bearing which
effectually prevents the cop from slipping or changing its position on
the spindle during the throw of the shuttle and the concussion at each
end of the throw.
Having now described and particularly set forth the nature of the
said Invention and the manner of carrying the same into effect, I would
have it understood what I claim as the Invention is,―
First. The combination with a loom shuttle spindle of a head c con-
structed with a projecting lug or stop & abutting against the portion of
the shuttle at e and the coiled spring 9 on the end of the spindle as
described.

page_text: Second. I claim the combination with a loom shuttle of a yielding
metallic point h and the shell or holder g, as and for the purpose set
forth.
Third. I claim a loom shuttle spindle constructed with the enlarged
ends of the slot, the thin portions 1, l, m, m, at and near the ends of
the slot, and the thicker portions n, n, of the sides, all as and for the
purpose specified.
In witness whereof, I, the said William Morgan-Brown, have here-
unto set my hand and seal, this Twenty-ninth day of April, in
the year of our Lord One thousand eight hundred and seventy-
six.
WILLIAM MORGAN-BROWN. (L.s.)
