IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1870

page_text: LETTERS PATENT to Humphrey Bracewell and John Bulcock, of
Burnley, in the County of Lancaster, Machine Makers, and
George Whittaker, of the same Place, Foreman, for the Invention
of "IMPROVEMENTS IN LOOMS FOR WEAVING"
Scaled the 4th April 1871, and dated the 6th October 1870.
PROVISIONAL SPECIFICATION left by the said Humphrey Bracewell,
John Bulcock, and George Whittaker at the Office of the Com-
missioners of Patents, with their Petition, on the 6th October
1870.
We, HUMPHREY BRACEWELL and JoHN BULCOCK, of Burnley, in the
County of Lancaster, Machine Makers, and GEORGE WHITTAKER, of the
same Place, Foreman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
-
This Invention malatos to the "small" of the shuttle box or the lever

page_text: and also to lift the stop rod lever clear of the "frog" when the shuttle
is in the box. Heretofore this lever has been hinged to the back of the
shuttle box in a permanent position whereby some difficulty was
experienced in the setting or adjusting of it, so as to fit the side of the
shuttle when in the box, and to act properly on the stop rod lever. Also
that by the constant wear of the parts it was necessary to be frequently
reset or adjusted, and thereby causing a recurrence of the difficulty of
adjusting it..
Now to remedy this evil we construct and fix to the box back a plate
having a slot hole formed therein suitable for the "swell" to work
freely in it, and on one end of this plate is a projecting, lug or bracket
having a slot hole in which to fix a stud, and upon this stud one end
of the "swell" is hinged, the other end of the said "swell" being
suitably formed to bear upon the plate or upon a leather cushion fixed
thereon to prevent noise. The slot hole in the lug being at or about
right angles to the shuttle box the stud upon which the swell is hinged
can be readily moved in or out from the box, and thus adjusted or set
to actuate the stop rod properly, and also the shoulder of the said stud
can be fitted to the lug so that the swell will fit to the side of the
shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Humphrey Bracewell, John Bulcock, and George
Whittaker in the Great Seal Patent Office on the 5th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HUMPHREY
BRACEWELL and JOHN BULCOCK, of Burnley, in the County of Lancaster,
Machine Makers, and GEORGE WHITAKER, of the same Place, Foreman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of October, 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 us, the said Humphrey Bracewell, John Bulcock, and George
Whitaker, Her special licence that we, the said Humphrey Bracewell,

page_text: John Bulcock, and George Whitaker, our executors, administrators, and
assigns, or such others as we, the said Humphrey Bracewell, John
Bulcock, and George Whitaker, 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 LOOMS FOR WEaving,” upon
the condition (amongst others) that we, the said Humphrey Bracewell,
John Bulcock, and George Whitaker, 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 per-
formed, 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 we, the said Humphrey Bracewell, John
Bulcock, and George Whitaker, 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
and accompanying Sheet of Drawings (that is to say) :—
This Invention relates to the "swell" of the shuttle box or the lever
which is employed therein to hold the shuttle or prevent its rebound,
and also to lift the "stop rod "lever clear of the "frog" when the shuttle
is in the box. Heretofore this lever has been hinged to the back of the
shuttle box in a permanent position whereby some difficulty was
experienced in the setting or adjusting of it, so as to fit the side of the
shuttle when in the box and to act properly on the "stop rod" lever.
Also that by the constant wear of the parts it was necessary to be.
frequently reset or adjusted and thereby causing a recurrence of the
difficulty of adjusting the said lever.
Now to remedy this evil we construct and fix to the box back a plate
having a slot hole formed therein suitable for the "swell" to work freely
in it, and on one end of this plate is a projecting lug or bracket having
a slot hole in which to fix a stud, and upon this stud one end of the

page_text: "swell" is hinged, the other end of the said "swell" being suitably
formed to bear upon the plate or upon a leather cushion fixed thereon
to prevent noise. The slot hole in the lug. being at or about right
angles to the shuttle box the stud upon which the "swell" is hinged
box, and thus adjusted or sét
can be readily moved in or out from the
to actuate the stop rod properly and also the shoulder of the said stud
can be fitted to the lug so that the "swell" will fit to the side of the
shuttle.
formed to bear upon the plate or upon a leather cushion fixed thereon
to prevent noise. The slot hole in the lug. being at or about right
angles to the shuttle box the stud upon which the "swell" is hinged
can be readily moved in or out from the box, and thus adjusted or sét
to actuate the stop rod properly and also the shoulder of the said stud
can be fitted to the lug so that the "swell" will fit to the side of the
shuttle.
In order that the Invention may be fully understood, we herein give
reference to an accompanying Sheet of Drawings illustrative thereof.
Fig. 1 is the back elevation of a shuttle box back, shewing our im-,
provements; Fig. 2 is a plan of the same; and Fig. 3 is the inside
elevation of the said box back.
A is the plate which is fixed by screw bolts B to the box back;
C is the "swell" which is hinged at one end on a stud C', fixed in a
slot hole of the projecting lug D, which is cast with the plate. The
"swell'
is formed to work freely in and through a slot hole of the
plate, and the other end to beat and bear upon a leather cushion E which
prevents noise.
"
It will now be readily seen that this stud can be quickly adjusted and
fixed in the lug so as to cause the "swell" to protrude a suitable
distance into the box so as to bring the shuttle central with the picker as
well as for it to produce a proper action on the stop rod. Also that the.
collar of the stud can be readily fitted to the lug so as to have the
"swell" to fit or lay properly or evenly against the side of the shuttle,
or instead of the "swell" being adjustable by means of the slot in the'
lug a mechanical equivalent may be adopted by constructing the said
"swell" with an adjustable joint, as shewn at Fig. 4, but we prefer
the former as more simple and less costly.
Having thus described the nature of the said Invention, and shewn
by Drawings in what manner the same is to be and may be performed
we would have it understood that we do not confine ourselves to the
precise details as herein set forth, as modifications may be made therein,
but what we claim as of our Invention is, the constructing and applying

page_text: "swells " to shuttle boxes of looms for weaving so as to be readily
adjusted for purposes herein explained.
In witness whereof, I, the said George Whitaker, for and on
behalf of myself and the said Humphrey Bracewell and John
Bulcock, have hereunto set my hand and seal, this Fourth
day of April, in the year of our Lord One thousand eight hundred
and seventy-one.
Signed, sealed, and delivered
by the within-named George
Whitaker, in the presence
of
