IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1869

page_text: LETTERS PATENT to Henry Mason, of Bradford, in the County of
York, Spinner and Manufacturer, Greenwood Hartley, of 3, Bright
Strect, Lister Hills, Horton, near the said Bradford, and John
Hindle, of 115, Otley Road, Bradford, aforesaid, for the Invention
Sealed the 31st August 1869, and dated the 9th March 1869.
PROVISIONAL SPECIFICATION left by the said Henry Mason, Green-
wood Hartley, and John Hindle at the Office of the Com-
missioners of Patents, with their Petition, on the 9th March
1869.
We, HENRY MASON, of Bradford, in the County of York, Spinner
and Manufacturer, GREENWOOD HARTLEY, of 3, Bright Street, Lister
Hills, Horton, near the said Bradford, and JouN HINDLE, of 115, Otley
Road, Bradford, aforesaid, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The object of the Invention is to obtain increased steadiness and
certainty in working. For this purpose we apply an extra swell or other
suitable elastic retaining means adapted to act on the picker to steady

page_text: it after picking the shuttle from one side to the other. These retaining
means will admit of the picker passing it in picking, but it prevents
the too free rebound, and retains it in position better to receive the
shuttle from the opposite side. By these means greater certainty in
picking and ease in working the loom with less wear and tear of the
parts are obtained.
The improvements are applicable to different classes or arrangements
of looms.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Mason, Greenwood Hartley, and John
Hindle in the Great Seal Patent Office on the 8th September
1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
MASON, of Bradford, in the County of York, Spinner and Manufacturer,
GREENWOOD HARTLEY, of 3, Bright Strect, Lister Hills, Horton, near
the said Bradford, and JOHN HINDLE, of 115, Otley Road, Bradford,
aforesaid, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of March, in the year
of our Lord One thousand eight hundred and. sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Mason, Greenwood Hartley,
and John Hindle, Her special license that we, the said Henry Mason,
Greenwood Hartley, and John Hindle, our executors, administrators, and
assigns, or such others as we, the said Henry Mason, Greenwood Hartley,
and John Hindle, our exccutors, 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, excrcise, 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 Henry Mason, Greenwood Hartley, and John
Hindle, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one
of us or them, should particularly describe and ascertain the nature of

page_text: 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 we, the said Henry Mason and Greenwood
Hartley, on behalf of ourselves and the said John Hindle, 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 :-
The object of the Invention is to obtain increased steadiness and
certainty in working. For this purpose we apply an extra swell or other
suitable elastic retaining means adapted to act on the picker to steady
it after picking the shuttle from one side to the other. These retaining
means will admit of the picker passing it in picking, but it prevents
the too free rebound, and retains it in position better to receive the
shuttle from the opposite side. By such means amongst the advantages
gained are greater certainty in picking, and ease in working the loom,
with less wear and tear of the parts. By the increased certainty and
steadiness of picking obtained slipping and consequent waste of the
weft or yarn from the shuttle bobbins or cops will to be a great extent,
if not entirely, avoided and considerable saving of such yarn effected.
The improvements are applicable to different classes or arrangements
of looms.
But that the Invention may be fully understood we will, by the aid of
the accompanying Drawing, proceed to describe means which we adopt
in carrying the same into effect.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a front view and Figure 2 a plan view of a portion of
one end of the batten of a loom with our improvements applied thereto.
a is the shuttle box which with the race b is of the ordinary character
affixed to a sword b'. The picker c is indicated by dotted lines, and
when actuated it is capable of sliding on the picker rod c¹ as is well
understood. d is the extra swell, separate views of which are shown by
Figures 3 and 4. This swell is supported in an opening formed for it
in the back of the upper part of the shuttle box in a line with the race
CLL
1.

page_text: for this purpose in holes or sockets formed for it in the back of the
shuttle box. e is a spring, one end of which is affixed by set screws e¹ to
the back of the shuttle box, whilst the other end acts on the back of
the swell d with a tendency to force its bellied part d' into position
to exert a gentle pressure on the picker as it passes that swell. The
pressure of the spring so as to vary the pressure exerted by the swell
may be adjustable. By the use of a swell acting as stated the picker
will be stayed when it has picked the shuttle from one side to the
other, and it will be prevented from rebounding. At the same time
The picker will be free to pass the swell in picking, and will be kept
steady to receive a shuttle from the box on the opposite side of the loom.
d
We do not confine ourselves to the form of swells used or the precise
mode of their action, as these may be varied, and the swell in place of
being a separate instrument may be formed on or as part of the spring.
the improvements are equally applicable to circular or rising or other
moving box looms.
Having thus described our Invention we would have it understood
that what we claim is the application of elastic swells to act on the
pickers for the purpose substantially as stated.
In witness whereof, we the said Henry Mason and Greenwood Hartley,
have hereunto set our hands and seals, this Thirty-first day of
August, in the year of our Lord One thousand eight hundred and
sixty-nine.
