IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF LACE
Year: 1855

page_text: LETTERS PATENT to John Foster, of Long Eaton, in the County of Derby,
Machine Builder, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
THE MANUFACTURE OF LACE."
Sealed the 7th Aug. 1855, and dated the 12th February 1855.
PROVISIONAL SPECIFICATION left by the said John Foster at the
Office of the Commissioners of Patents, with his Petition, on the 12th
February 1855.
1, JOHN FOSTER, of Long Eaton, in the County of Derby, Machine
Builder, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF LACE" to be as follows:-
My Invention consists in the employment of one or two half jack shafts
placed above the net beam to work the landing bars of the machine. I prefer
working with two half jack shafts.
The advantages derived from my Invention are, the giving or imparting to
the landing bars superior motion to those now in use, and also the removing of
cumbrous machinery of back shafts and goose necks and half jacks both in the
front and back parts of the machine to more convenient parts thereof, so as to
render more convenience and afford greater facilities to the operations of
the workman. By this arrangement, the goose necks are removed from
chafing and frequently breaking the warp threads, thereby saving the time

page_text: of the workman, besides affording him much easier access to various parts of
the machine both in front and at back thereof. By my Invention I also give
greater facilities for the application of guide bar brackets, now so much in
request in this description of machinery, and for jacking the threads, or for the
application of the spool principle, besides rendering more convenience generally
to the operations of the workman employed on the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
-by the said John Foster, in the Great Seal Patent Office on the 11th
August 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FOSTER, of Long Eaton, in the County of Derby, Machine Builder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of February, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said John Foster, Her special licence that I, the said John
Foster, my executors, administrators, and assigns, or such others as I,
the said John Foster, 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 "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF LACE," upon the condition
(amongst others) that I, the said John Foster, by an instrument in writing
under my hand and seal, 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 John Foster, 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 thereof, reference being had to the Drawing hereunto annexed,
that is to say:-
My Invention relates especially to what are known as Lever's twist lace

page_text: machines, and consists in the employment of one or two half jack shafts placed
above the net beam to work the landing bars of the machine. I prefer
working with two half jack shafts.
The advantages derived from my Invention are, the giving to the landing
bars superior motion to that now imparted to them, and also the removing of
the cumbrous machinery of back shafts, goose necks, and half jacks both in the
front and back parts of the machine to more convenient parts thereof, so as to
afford more convenience and greater facilities to the operations of the workman.
By this arrangement, the goose necks are removed from chafing and frequently
breaking the warp threads, thereby saving the time of the workman, besides
affording him much easier access to various parts of the machine both in front
and at back thereof. By my Invention I also give greater facilities for the
application of guide bar brackets, now so much in request in this description of
machinery, and for jacking the threads, or for the application of the spool
principle, besides affording more convenience generally to the operations of the
workmen employed on the machine.
The annexed Drawing represents so much of a Lever's twist lace machine
as is necessary to shew my Invention. a is part of the framing; b, the driving
shaft, having a crank c keyed on the end, which gives motion to the lever d.
This lever is connected to the levers e, e, which levers move the arms f,f,
which are keyed on to the front and back half jack shafts g. 9; these shafts
also carry the half jack shaft arms h, h, by which the half jacks i, i, which are
attached to the landing bars, are raised and depressed. is the net beam.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that what I claim is, the mode
of working the landing bars in Lever's twist lace machines by means of two half
jack shafts placed above the net beam, as herein-before exemplified and
described.
In witness whereof, I, the said John Foster, have hereunto set my hand
and seal. this Tenth day of August. One thousand eight hundred and
Witness,
JOHN ROBINSON,
Nott".
