Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
BAILEY, of the Borough of Leicester, Frame Smith, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-ninth day of December, in the sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Benjamin Bailey, Her especial licence, full power, sole privilege and authority,
that I, the said Benjamin Bailey, my exors, admors, and assigns, or such
others as I, the said Benjamen Bailey, my exors, adiñors, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN MACHINERY EMPLOYED
IN THE MANUFACTURE OF STOCKINGS, GLOVES, AND OTHER FRAMEWORK KNITTED
FABRICS;" in which said Letters Patent is contained a proviso that I, the
said Benjamin Bailey, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Benjamin Bailey, do hereby declare that the nature of my Invention, and and
the manner in which the same is to be performed, are fully described and

page_text: ascertained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say:-
My Invention relates, first, to a mode of so arranging parts of á framework
knitting machine that the pressure of the springs is relieved from the jacks
during certain of the movements thereof.
Secondly, my improvements relate to a mode of constructing the falling bar
whereby the rebound of the jacks is reduced. And,
Thirdly, my Invention relates to a mode of constructing the slurcock.
And in order that my Invention may be fully understood and readily carried
into effect, I will proceed to explain the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
The Drawings represent various views of parts of a stocking machine or knit-
ting frame, full size. The nature of each view being written on the Drawings,
it will not be necessary to repeat them here, the ordinary parts being simply in
outline; the parts which are varied and newly arranged being colored, so that
a workman looking over the Drawings will be enabled readily to trace the
nature of the improvements, aided by the description hereafter given.
The construction and manner of working stocking machinery or knitting
frames being well understood, it will not be necessary to enter into a descrip-
tion thereof in this my Specification. a, a, are what are called the half jacks,
which are continued back beyond the axis of their motion, as is shewn, the
back end of each having a curved plate a¹ in which is formed a notch a³, and
through the plate is formed, an opening a through which a projecting stud c
of the plate 6 works; this plate 6 moves on an axis d affixed to the half jack,
as is shewn; the object of this plate is to cause the notch a³ in the plate a¹
to be covered at proper intervals, as will be hereafter explained, each of the
half jacks being fitted similarly to the other with the parts above described,
and the plates are pressed downwards by means of springs d* pressing on the
projecting studs d'. The spring bar e, which carries the springs f of the jacks, s
in place of being a fixture to the carriage of the jacks, is caused to move on
axes or centre pins f¹ in order to facilitate the relieving of the springs from
the jacks. The Drawings clearly shew the nature of the springs f which are
affixed in the spring bar e. The spring bare has two arms g affixed thereto,
one at each end, and to the front of the carriage are affixed two arms h, h,
one at each end, and the arms h, g, h, g, at each end of the machine are
combined by springs i, one of which only being shewn; these springs draw the
lower ends of the arms g towards the lower ends of the arms h, by which

page_text: the springs will at all times, when permitted so to do, act strongly on the
jacks, as is shewn in the Drawings. On the spring bar e are affixed the
uprights j, j, which have each a roller k moving on an axis, the position of
which can be adjusted in the openings formed through the upper parts of the
uprights j, j, and the rollers k will be permitted to enter the notches when
the covering plates 6 are raised up by their coming against the curved surfaces
formed on the tops of the uprights 7, 7, which are fixed to the framing of the
machine, as shewn.
The Drawings shew the parts of the machine in the positions they would
assume just before drawing the jacks, and the springs f will be removed from.
the tails of the jacks when the frame descends for dividing the threads into
loops between the needles by means of the lead sinkers, and the rollers k
will be forced out of the notches in the plates a¹ at the back ends of the half
jacks, and when the frame again goes over the arch (as it is technically called)
the springs will again come on to the tails of the jacks in consequence of
the plates b being supported by the curved surfaces or stops, which allow of
the rollers k again entering their respective notches in the plates a formed
or affixed at the back ends of the half jacks, as above described; by this
arrangement the jacks will be relieved of the pressure of the springs, except-
ing at those times when the pressure is necessary, by which a great advantage
will be found in working of the machine. m is the falling bar, which is so
formed as to cause the jacks to fall dead in place of causing them to rebound
as heretofore. For this purpose I apply a soft material under the surface on
which the jacks fall; by this means the falling bar damps the fall, and
prevents the rebound.
In constructing a falling bar according to my Invention, I prefer to use
a layer of lead m', though wood or other material may be used, under the
surface on which the jacks fall, the parts being secured together by rivetting
or otherways. n is the slurcock, which has two sliding pieces n¹ in place of
one, each sliding piece having its spring o, o, the two springs offering about
the same amount of pressure as the single spring of the ordinary slurcock.
By this arrangement the jacks will be drawn by the highest point of the
slurcock coming under them, consequently the forced used will only be half
as much as that ordinarily used; hence, if there be any stopping of a jack by
the thread, the jacks will be less liable to injury than heretofore, whilst at
other times the slurcock will act with the force of the two springs, and the
whole surface of the slurcock will be brought into action, and therefore act
with all the strength of the slurcocks heretofore used.
Having thus described the nature of my Invention, and the best means

page_text: I am acquainted with for performing the same, I would remark that I make
no claim to any of the parts separately, nor do I confine myself to the details
shown and described so long as the peculiar character of either part of my
.Invention be retained. But what I claim is,―
First, the mode of constructing and combining parts of stocking machines
.or knitting frames whereby the jacks are relieved from the pressure of their
springs for a time, as herein described.
Secondly, I claim the mode of constructing falling bars for the jacks by
applying a soft or damping substance below the surface on which the jacks fall,
in order to prevent the rebound of the jacks; and,
Thirdly, I claim the mode of forming the slurcock, as above described.
In witness whereof, I, the said Benjamin Bailey, have hereunto set my
hand and seal, this Twenty-seventh day of June, in the year of our
Lord One thousand eight hundred and forty-three.
Leicester.
AND BE IT REMEMBERED, that on the Twenty-seventh day of June,
in the year of our Lord 1843, the aforesaid Benjamin Bailey came before our
said Lady, the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according to
the tenor of the Statute made for that purpose.
