Year: 1876

page_text: LETTERS PATENT to Abraham Lord, of Middleton, in the County of Lancaster,
Manufacturer, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said John Lord at the Office of
the Commissioners of Patents on the 10th April 1876.
ABRAHAM LORD, of Middleton, in the County of Lancaster, Manufacturer.
"IMPROVEMENTS IN LOOMS FOR WEAVING."
The improvements relate to what are called "dobbies," or modified forms of
jacquard, and are intended as a means of simplifying the action of the same in
the manufacture of certain fabrics wherein a border is required to be woven, as in
the case of pocket handkerchiefs and other bordered fabrics.
In weaving any fabric where a border is desired to be continued across the
breadth of the cloth a considerable length of cloth has to be woven before any change
is required (either in the form of treading the yarn or in the shuttle used), and in
the case of the ordinary dobbies this has to be accomplished by means of a long
series of cards, chains, or other means of actuating the "dobby" mechanism,
according to the particular construction thereof.
Now the object of my Invention is to so construct such "dobbies" that the
cards, chains, or other analogous means of actuating the same will only come into
operation when it is desired to weave such border, and that such cards, chains,
or other analogous means will remain stationary, while the central or main
portion of the fabric is being woven, whereby much saving in such cards, chains,
and so forth, as well as of wear and tear of machinery, will be effected.
To obtain these results, and to carry into effect my improvements, I use, by
preference, those kinds of "dobbies" which cause the loom to continue weaving
plain cloth when the actuating cards or other analogous mechanisms are at rest.
In such cases the barrel or cylinder carrying such cards or substitutes therefor
is turned by means of a paul and ratchet motion. I affix to any convenient part of
this ordinary dobby or modified jacquard a disc or tappet, or it may be another
barrel or cylinder carrying cards or substitutes therefor, which disc, tappet, or

cylinder I cause to be driven by means of geared wheels continuously, or, by
preference, by means of a star wheel or other analogous notion intermittently.
This disc, or substitute therefor, I so form that when the weaving has progressed
a sufficient distance in the ordinary manner it will actuate a lever by depressing
or raising the same, which lever is attached by a link or other suitable
means to the paul of the ratchet before described, as being part of the ordinary
dobby" machine or modified jacquard, thereby allowing such, paul to fall in gear
with the ratchet, and thus setting the barrel or cylinder forming the pattern of
the border in motion, whether such border be formed by means of a change in
the manner of actuating the threads, or by a change of shuttle, or by both
changes combined. When the disc, tappet, or substitute therefor, has progressed
in its motion as far as it is desired to continue the weaving of the border, the disc,
tappet, or substitute therefor, is so formed as to actuate the before mentioned
lever in the opposite direction, and thus raise or take the paul out of gear with the
ratchet, whereby the barrel or cyliner of the "dobby' or modified jacquard is
caused to remain stationary until the time for weaving the border again comes
round.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said John Lord in the Great Seal Patent Office on the 10th October 1876.

"IMPROVEMENTS IN LOOMS FOR WEAVING."
The improvements relate to what are called "dobbies" or modified forms of
jacquard looms, and are intended as a means of simplifying the action of the same
in the manufacture of certain fabrics wherein a border is required to be woven,
as in the case of pocket handkerchiefs and other bordered fabrics.
In weaving any fabric where a border is desired to be continued across the
breadth of the cloth a considerable length of cloth has to be woven before any
change is required, (either in the form of treading the yarn or in the shuttle used,)
and in the case of the ordinary dobbies this has to be accomplished by means of a
long series of cards, chains, or other means of actuating the "dobby" mechanism,
according to the particular construction thereof.
Now the object of my Invention is to so construct such "dobbies" that the
cards, chains, or other analogous means of actuating the same will only come into
.operation when it is desired to weave such border, and that such cards, chains,
or other analogous means will remain stationary while the central or main portion
of the fabric is being woven, whereby much saving in such cards, chains, &c., as
well as of wear, and tear of machinery, will be effected.
To obtain these results, and to carry into effect my improvements, I use by
preference those kinds of "dobbies" which cause the loom to continue weaving
plain cloth when the actuating cards or other analogous mechanisms are at rest.
In such cases the barrel or cylinder carrying such cards or substitutes therefor is
turned by ineans of a paul and ratchet motion. I affix to any convenient part of
this ordinary "dobby" or modified jacquard, a disc or tappet, or it may be another
barrel or cylinder carrying cards or substitutes therefor, which disc, tappet, or cylinder,
I cause to be driven by means of geared wheels continuously, or by preference by
means of a star wheel or other analogous motion intermittently. This disc or
substitute therefor I so form that when the weaving has progressed a sufficient
distance in the ordinary manner it will actuate a lever by depressing or raising
the same, which lever is attached by a link or other suitable means to the paul
of the ratchet before described, as being part of the ordinary "dobby" machine or
modified jacquard, thereby allowing such paul to fall in gear with the ratchet, and
thus setting the barrel or cylinder forming the pattern of the border in motion,

page_text: whether such border be formed by means of a change in the manner of actuating
the threads, or by a change of shuttle, or by both changes combined. When the
disc, tappet, or substitute therefor has progressed in its motion as far as it is desired
to continue the weaving of the border, the disc, tappet, or substitute therefor is so
formed as to actuate the before mentioned lever in the opposite direction, and thus
raise or take the paul out of gear with the ratchet, whereby the barrel or cylinder
of the "dobby" or modified jacquard is caused to remain stationary until the time
for weaving the border again comes round.
But that the Invention may be fully understood, I will, by the aid of the
accompanying Drawings, proceed to described means pursued by me in carrying
the same into effect.
Figure 1 represents an elevation, and Figure 2 shews a plan view of portions of
my improvements, in each of these views the same letters indicate corresponding
parts wherever they occur.
a, a, is a portion of the framing of the ordinary " dobby or modified jacquard,
the usual parts of which are not shewn, but which are constructed so as to be
controlled in their action by the cylinder or barrel b. This cylinder or barrel
is capable of being driven by the paul c attached to a lever actuated by the usual
working parts of the "dobby" or modified jacquard. The "dobbyi or modified
jacquard is so arranged as to cause the loom to weave plain cloth or other
continuous kind of weaving when the cylinder b is at rest. By this means the
only pattern or portion of the weaving necessary to be formed by the cards d or
substitutes therefor, carried, by the pattern cylinder or barrel b, is the border
of the fabric. It is therefore required that this cylinder or barrel b shall only be
put in motion when it is desired the weaving of the border shall take place. To
enable this to be done the ratchet wheel e is put in motion by the paul f; this
puts in motion the star wheel g (or other analogous mechanism), which, in turn,
communicates motion to the barrel or cylinder h, carrying a second set of cards h¹,
or substitutes therefor. At the required place these cards or substitute therefor
have holes or depressions formed in them, so that when they come in contact with
the lever they will depress the same. This lever being attached by means of the
link to the paul e permits the same to fall into gear, and so communicates motion
to the barrel or cylinder b, whereby the loom is caused to weave the pattern of the
border, whether such be formed by the change of the shuttle or the treading of
the yarn.
The cards on the cylinder h may be made to produce the same effect
by means of projections thereon if a modification of the lever or analogous
mechanism be used. Or a disc or tappet may be used for the same purpose.
An index may also be affixed to any convenient portion of the "dobby" or loom,
having suitable connections with the barrel or substitute therefor, arranged in
such manner that the cards will cause the same to register the number of
handkerchiefs, or such like fabrics woven.
Having thus described my improvements, and means which I adopt in carrying
the same into effect, I would have it understood that I do not confine myself to
the exact details shewn and described, as variations may be made in them without
departing from the peculiar character of my Invention, but what I do claim is-
The so arranging and constructing a disc, tappet, barrel, cards, or other substitute
therefore, affixed to suitable forms of "dobby or modified jacquard, which disc,
tappet, barrel, cards, or other substitute therefor, is so formed, and has such a con-
tinuous or intermittent motion communicated to it as shall cause it to actuate a
lever for the purpose of raising or depressing the paul used for driving the ratchet
of the cylinder or barrel of the "dobby" or modified jacquard, so as to take such
paul out of gear during the time in which the ordinary weaving takes place, and
by the contrary action, allowing the paul to take into gear, for the purpose of

weaving the border as desired, whether such "dobby' or modified jacquard is
intended to actuate the treading of the yarn, or the change of the shuttle, or both
of them combined.
In witness whereof, I, the said Abraham Lord, have hereunto set my hand
and seal, this Sixth day of October, in the year of our Lord One thousand
eight hundred and seventy-six.
