IMPROVE- MENTS IN LOOMS FOR WEAVING
Year: 1873

page_text: LETTERS PATENT to Thomas Longworth, of Blackburn, in the County
of Lancaster, Cotton Manufacturer, and Francis Lloyd Jones, of
Blackburn aforesaid, Mill Manager, for the Invention of "IMPROVE-
MENTS IN LOOMS FOR WEAVING."
Sealed the 22nd July 1873, and dated the 25th January 1873.
PROVISIONAL SPECIFICATION left by the said Thomas Longworth and
Francis Lloyd Jones at the Office of the Commissioners of Patents,
with their Petition, on the 25th January 1873.
We, THOMAS LONGWORTH, of Blackburn, in the County of Lancaster,
Cotton Manufacturer, and FRANCIS LLOYD JONES, of Blackburn aforo-
said, Mill Manager, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates to the apparatus employed on looms for weaving,
for the purpose of forming or producing the figured or fancy bordering

page_text: on co ttonpicces, and which heretofore has been produced by the action
of the "Dobbie" or similar apparatus, and our improvements consist of
improved apparatus for such purpose of a much more simple construc-
Lion, whereby we are enabled to dispenso with a great portion of the
apparatus as heretofore constructed.
We mount behind or near to the "heald shaft" a shaft having
theroon a number of discs. On one face of cach is a tappet; these
tappet discs slide on the shaft to a collar, against which they are held
by means of a nut on the shaft, a portion of which is chased or screwed
for the purpose. Tappet levers rest between the discs on the tappets,
and the healds for operating the border warp are connected to theso
levers in the ordinary manner, and rotation is imparted to the disc
tappet shaft and tappets by means of a lever catch and catch wheel, the
said lever being actuated by preference from the heald roller or othor
convenient going part of the loom.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Longworth and Francis Lloyd Joncs in
the Great Scal Patent Office on the 25th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, TшомAS
LONGWORTH, of Blackburn, in the County of Lancaster, Cotton Manu-
facturer, and FRANCIS LLOYD Jones, of Blackburn aforesaid, Mill
Manager, sond greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of January, in
the year of our Lord One thousand eight hundred and seventy-threc, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Thomas Longworth and Francis
Lloyd Jones, Her special licenco that we, the said Thomas Longworth
and Francis Lloyd Jones, our executors, administrators, and assigns,
or such others as we, the said Thomas Longworth and Francis Lloyd
Jones, 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,

page_text: usc, 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 Thomas Longworth and Francis Lloyd Jones,
our executors or administrators, by an instrument in writing under
our, 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 we, the said Thomas Longworth and Francis
Lloyd Jones, do hereby declare the nature of our said Invention, and
in what manner the same is to bo performed, to be particularly
described and ascertained in and by the following statement and accom-
panying Sheets of Drawings, that is to say:-
This Invention relates to the apparatus employed on looms for
weaving, for the purpose of forming or producing the figured or fancy
bordering on cotton picces, and which heretofore has been produced by
the action of the "Dobbie" or similar apparatus, and our improvements
consist of improved apparatus for such purpose of a much more simple
construction, whereby we are enabled to dispense with a great portion of
the apparatus as heretofore constructed.
We mount behind or near to the "heald shaft" a shaft having thereon
a number of discs. On one face of each is a tappet; these tappet dises
slide on the shaft to a collar, against which they are held by means of a
collar and nut on the shaft. Tappet lovers rest between the discs on
the tappets, and the healds for operating the border warp are connected
to these levers in the ordinary manner, and rotation is imparted to the
disc tappet shaft and tappets by means of a lever catch and catch wheel,
the said lever being actuated by preference from the tappet shaft or
other convenient going part of the loom.
In order that this Invention, together with the method of applying
and working the same may be clearly understood, we have hereunto
two Sheets of Drawings, and have marked the same with figures
and letters of reference, the same letter referring to the same part in
the various views or Figures.

page_text: apparatus.
Fig. 4 is a view enlarged of one of the disc tappets and part of one
of the tappet levers.
Figs. 5 and 6 shew two other forms of tappets for this purpose; and
Fig. 7, Sheet 2, is a detail shewing catch wheel operated by means of
bevel gear driving from the tappet shaft.
A is the top cross rail of the loom, to which is secured by bolts tho
standard or bracket B supporting the shaft C, on which are the tappets
D, D, D, bolted together by the bolts E, E, and held in proper position on
the said shaft by means of the adjustable bosses F, F. G is a stud
(supported by the standard or bracket B) on which are tho tappet
levers H secured in position by means of the adjustable bosses J. Tho
cords K are connected with and operate the healds for producing the
figured or fancy border as usual. L is the ordinary tappet shaft on
which is the tappet L', which at each revolution operates the lever M and
by means of the connecting rod N causes the bell crank lever P (on tho
shaft C) by raising the same to operate or draw back the catch R. The
catch thus by means of the pins S turns the catch pin wheel T, shaft O,
and the tappets D, D, D, and so operates the tappet levers II and
cords K. The tappets D, D, D, will of course bo made of form and
number of lifts, according to the pattern required, and will be applied
and arranged with similar apparatus to that described at the other side
of the loom for producing the figured or fancy border at the opposite
side of the cloth. T" is a blade spring for holding the catch pin wheel T
steady. At Fig. 7, for the connecting rod N is substituted a shaft N, on
which at the foot is the worm wheel W driven by the worm L' on the
ordinary tappet shaft L, for the purpose of operating the catch pin
wheel T by means of the bevel wheels P and R, the latter being keyed
on the shaft O.

In witness whercof, I, the said Francis Lloyd Jones, for and on
behalf of myself and the said Thomas Longworth, have herc-

the year of our Lord One thousand eight hundred and seventy-
three.
