NEW OR IMPROVED JACQUARD MACHINE OR MECHANISM FOR PRODUCING IN FABRICS ORNAMENTATION OF PROVISIONAL SPECIFICATION ATION OF VARIOUS KINDS FOR HOSIERY AND OTHER PURPOSES
Year: 1881

page_text: LETTERS PATENT to John Brenthall, of Sherwood Rise, Mansfield, in the
County of Nottingham, for an Invention of "NEW OR IMPROVED JACQUARD
MACHINE OR MECHANISM FOR PRODUCING IN FABRICS ORNAMENTATION OF
PROVISIONAL SPECIFICATION left, by the said John Brentnall at the Office
of the Commissioners of Patents on the 9th June 1881.
JOHN BRENTNALL, of Sherwood Rise, Mansfield, in the County of Nottingham.
"NEW OR IMPROVED JACQUARD MACHINE OR MECHANISM FOR PRODUCING
IN FABRICS ORNAMENTATION OF VARIOUS KINDS FOR HOSIERY AND OTHER
PURPOSES."
This Invention has for its object improvements in producing in fabrics orna-
mentation of various kinds made on hosiery machinery in openwork, and also for
the insertion of various colours, the ornamenting of woollen shawls of all kinds,
and all kinds of curtains made on said machinery. It has also for its object the
manufacture of the old point net lace made on all kinds of hosiery machinery.
In carrying out my Invention I adopt mainly the following arrangements:-
To an ordinary hosiery machine I fix by suitable means a frame carrying points
working freely when the machine is in action. The said points work between
comb bars. The pin is connected or forms part with the bolt, to the front of which
is the point. Around each pin is coiled a spring. To the back of the pin is fitted
the perforated cylinder, over which the perforated cards for producing the pattern
are worked by ordinary means, either by hand or steam.
The action is as follows:-
The frame is fitted to the machine, and being set in motion, the cards travelling
over the cylinder press, according to the pattern required, the pin, bolt, and point
out, and the pattern required is produced by the ordinary mode. The springs on
the pins bring the points back to normal position.

"NEW OR IMPROVED JACQUARD MACHINE OR MECHANISM FOR PRODUCING
IN FABRICS ORNAMENTATION OF VARIOUS KINDS FOR HOSIERY AND OTHER
PURPOSES."
This Invention has for its object improvements in producing in fabrics orna-
mentation of various kinds made on hosiery machinery in openwork, and also
for the insertion of various colours, the ornamenting of woollen shawls of all kinds,
the throwing of the back stitch into ornamental figures, and all kinds of curtains
made on said machinery. It has also for its object the manufacture of the old
point net lace made on all kinds of hosiery machinery.
In carrying out my Invention I adopt the following arrangements :-To an
ordinary hosiery machine I fix by suitable means a frame carrying points working
freely when the machine is in action. The said points work between comb bars.
The pin is connected or forms part with the bolt, to the front of which is the point.
Around each pin is coiled a spring. To the back of the pin is fitted the perforated
cylinder, over which the perforated cards for producing the pattern are worked by
ordinary means, either by band or steam.
Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed, I will now proceed (by
reference to the accompanying Drawings) to further and particularly describe and
ascertain in what manner the same is to be performed or carried out in practice.
Fig. 2, side elevation.
A is the frame of the improved jacquard, having in each side two V shaped slides
in which the bearings of the square cylinder B move. This cylinder B is perforated
on each side with four rows of holes corresponding with the pins of the bolts, the
holes being of such a size as to allow of the pins passing easily through them. The
movement of the cylinder is caused by a handle on a shaft C, on which shaft are
fixed two pinions working in racks on the back of the bearings of the cylinder.
D is a perforated plate, the holes in which agree with the holes in the cylinder, and
through which the pins of the bolts work. On the spindle of the cylinder on the
opposite side of the machine to that on which the handle works is fixed a collar E,
with four studs as shown, one of which studs engages with a catch bar every time
the cylinder is raised, and turns it a quarter of a revolution, when it is again
lowered. The cylinder is prevented from turning too far by a spring, which keeps
a T piece pressed against the top of the square flange of the collar E. F, F, are
the bolts working through combs G. G. Each bolt has attached to the top a point,
and to the bottom a pin on which a spiral spring is coiled, the object of the spring
being to keep the bolts all down when the machine is at rest. The lower part of
the pins is round, the upper part being flattened to pass between the combs; and so
that there may be room for them, they are arranged in four rows (as shown in
Fig. 2), every fourth bolt being identical. The plate H can be taken off so as to
allow of any one of the bolts being replaced, the combs being held in place by the
Tshaped piece J.
The modus oqerandi is as follows:-A series of cards perforated so as to give
the required pattern is passed over the cylinder B, being kept in place by the studs

page_text: at each end of it; the handle is then moved so as to cause the cylinder to rise and
bring the card in contact with the pins of the bolts. All those not required to move
have holes punched for them in the card; the rest of it being blank causes tho
corresponding bolts and their points to rise when it is raised to alter the threads
to and fro as required upon the needle of the hosiery frame. When the operation
is completed, the cylinder is lowered (the catch bar turning it over), and the same
thing is repeated as above described.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or put in
practice, I hereby declare that I claim the said Invention of "New or Improved
Jacquard Machine or Mechanism for Producing in Fabrics Ornamentation of various
kinds for Hosiery and other Purposes," substantially as herein before set forth and
described and illustrated in the accompanying Drawings, wherein the following are
particular and important points or features:-
(1). The movable bolt to which is fastened a pin, and around which is coiled a
spring, said bolt being capable of working either horizontally or upright, sub-
stantially as hereinbefore set forth and described.
(2). The said movable cylinder over which the cards pass, and which act upon
the pins attached to the bolts, as above mentioned.
(3). The application of the card for stocking or hosiery machinery, substantially
as and for the purpose described.
In witness whereof, I, the said John Brentnall, have hereunto set my hand
and seal, this Third day of December, in the year of our Lord One thousand
eight hundred and eighty one.
