IMPROVEMENTS IN Looms
Year: 1868

page_text: LETTERS PATENT to William Millard, of Trowbridge, in the County
of Wilts, Engineer, for the Invention of "IMPROVEMENTS IN Looms."
PROVISIONAL SPECIFICATION left by the said William Millard at the
Office of the Commissioners of Patents, with his Petition, on the
6th August 1868.
I, WILLIAM MILLARD, of Trowbridge, in the County of Wilts,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN Locms," to be as follows:-
The improvements are more especially applicable to power looms for.
weaving check patterns, and comprise sinking square or rectangular-
shaped grooves in the back of the frame holding the shuttle boxes, and
providing guides of corresponding shape working in the grooves and,
fastened to the shuttle boxes.
Also an arrangement similar to the above, excepting the substitution
for the grooves and guides of half circular or partly circular shaped
grooves and guides in either case to correspond. The intention is to
cause the shuttle boxes to stand more firmly to their work and avoid

page_text: tendency to kick. Also the improvements comprise working the said
grooves and slides, or either of them, with the grooves sunk in the slay
sword or vibrating upright which carries the slay beam at one end and
into cap securing slide at the other.
The mode of performing the Invention is to apply fittings of metal to
the parts of the loom referred, having planed on or on them the grooves
and slides as above set forth.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Millard in the Great Seal Patent Office
on the 6th February 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MILLARD, of Trowbridge, in the County of Wilts, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of August, in the year
of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Millard, Her
special licence that I, the said William Millard, my executors, adminis-
trators, and assigns, or such others as I, the said William Millard,
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 "Iм-
PROVEMENTS IN Looms," upon the condition (amongst others) that I, the
said William Millard, 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 Millard, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
The improvements are more especially applicable to power looms for
weaving check patterns, and have for their object the causing the
shuttle boxes to stand more firmly to their work and avoid tendancy to
kick; they comprise sinking square or rectangular and circular or partly
circular grooves in the back of the frame holding the shuttle boxes, and
providing guides of corresponding shape (or nearly so) working in such
grooves and fastened to the shuttle boxes. Also making the said grooves
and slides, or either of them, with the grooves sunk in the slay sword or
vibrating upright which carries the slay beam at one end and and into
cap securing slide at the other.
The mode of performing the Invention is to apply fittings of metal to
the parts of the loom referred to, having planed in or on them of suitable
dimensions the grooves and slides, as above set forth, and as illustrated
by the Drawings hereunto annexed.
Figure 1 represents a back elevation of a frame holding shuttle boxes;
Figure 2, sectional plan of the same. In each side of the frame at C are
planed grooves, rectangular or circular, as the case may be, in which
slide circular-headed slides B, Figure 2, or rectangular-headed slides A,
as in Figures 3 and 4, which slides are firmly fastened to the shuttle
boxes, as shown. The cap G, Figures 1, 2, and 4, fits partially over the
slide to keep it in position on one side, and on the other side the slide is
secured by the projecting lip D (Figures 2 and 3) of the slay sword or
vibrating upright E (only shown in section in Figures 2 and 3) which
carries the slay beam. F, Figure 2, is the shuttle box. The slides are
made slightly smaller than the grooves in which they are intended to
work, so as to allow of the passage of a lubricant and easy motion. In
some cases I make the grooves and slides, or either of them, sunk or
projecting, as the case may be, in or from the slay sword E and the
cap G, but I prefer to use the methods shown in the Drawing.
In witness whereof, I, the said William Millard, have hereunto set
my hand and seal, this Fifth day of February, in the year of our
Lord One thousand eight hundred and sixty-nine.
WILLIAM MILLARD. (L.S.)
