CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1867

page_text: LETTERS PATENT to Edward Lord, of Todmorden, in the County of
York, Machine Maker, for the Invention of "CERTAIN IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 6th August 1867, and dated the 16th February 1867.
PROVISIONAL SPECIFICATION left by the said Edward Lord at the
Office of the Commissioners of Patents, with his Petition, on the
16th February 1867.
I, EDWARD LORD, of Todmorden, in the County of York, Machine Maker,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN LOOMS FOR WEAVING," to be as follows:-
My Invention consists in an improved combination of machinery for
working the healds of looms when the top and bottom bars of the healds are
connected together by rigid ends; these rigid healds are worked up and
down by levers or treadles which are actuated in any required succession,
according to the fabric to be woven, by a series of tappet plates having
elevators and depressors of the usual construction, or by a drum with
projections or other equivalent placed within the framing of the loom and
turned round by a pinion on the tappet shaft, gearing into a wheel on the
axle of the tappet plates; or the rigid healds may be raised and lowered by
tappets on the tappet shaft.

page_text: My improvements are particularly beneficial when applied to looms for
weaving fabrics requiring several healds, but it may be used advantageously
when only two healds are used. In all cases the usual top rail and roller
shaft are dispensed with, the loom is simplified, and head room is economised.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Lord in the Great Seal Patent Office on the
15th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LORD, of Todmorden, in the County of York, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Edward Lord, Her special license that I, the said Edward Lord, my
executors, administrators, and assigns, or such others as I, the said Edward
Lord, 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 "CERTAIN IMPROVEMENTS
IN LOOMS FOR WEAVING," upon the condition (amongst others) that I, the
said Edward Lord, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Edward Lord, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
My Invention consists in an improved combination of machinery for
working the healds of looms when connected together and suspended in
rigid frames. The healds are worked up and down by levers or treadles,
which are actuated in any required succession according to the fabric to be
woven by a series of tappet plates, having elevators and depressors of the

page_text: usual construction, or by a drum with projections or other equivalents placed
within the framing of the loom, and turned round by a pinion on the tappet.
shaft, gearing into a wheel on the axle of the tappet plates; or the healds
may be raised and lowered by tappets on the tappet shaft.
And in order that my Invention may be fully understood and readily
carried into operation I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is an end view, and Figure 2 a front view of the principal parts
of an ordinary power loom to which my improvements are applied; Figure 3
is a plan of part of my improvements.
a is the crank shaft, and 6 the tappet shaft, to which is fixed by set
screw the bevel pinion gearing into the wheel c; there is a second bevel
pinion 6 on the tappet shaft which can be brought into gear with the wheel c
when the speed thereof is to be altered so as to weave a different class of
cloth. To the wheel c is connected the series of tappet plates d which are
made as usual with elevators and depressors acting on the treadles e ;
these
tappet plates and the treadles are placed within the framing of the loom; the
treadles are jointed to the lower ends of the frames f, which are guided in the
grooved plates g fixed to the loom sides; the upper arms of the frames f are
bent inwards, and to them are suspended the healds h, the lower bars of the
healds being connected to the lower part of the frames f; by this means the
ordinary healds are worked up and down from the under side of the loom, and
are kept sufficiently elastic for preventing injury to the warp and reducing the
wear and tear of the healds.
My Invention may be modified by substituting a drum with projections or
other equivalents for working the treadles, or the healds may be raised and
lowered by tappets placed as usual on the tappet shaft.
My improvements are particularly beneficial when applied to looms for
weaving fabrics requiring several healds, but they may be advantageously used
in looms with only two healds. In all cases the usual top rail, roller shaft,
and top and bottom jacks are dispensed with, the loom is simplified, and the
healds and warp are easier of access.
Having thus stated the nature of my Invention, and described the manner
of performing the same, 1 declare that I claim as my improvements in..
looms,―
First, the rigid frames f to which the healds are connected, as shewn and
described.
And, secondly, placing the treadles and tappet plates or other equivalents by

page_text: which the healds are worked within and between the frame sides of the loom,
as shewn and described.
In witness whereof, I, the said Edward Lord, have hereto set my hand
and seal, this Thirteenth day of August, One thousand eight hundred
and sixty-seven.
