IMPROVEMENTS IN MACHINERY FOR MANUFACTURING LOOPED FABRICS
Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
BAILEY, 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-fourth day of February, in the seventh year 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 autho
rity, that I, the said Benjamin Bailey, my exors, adññiors, and assigns, or such
others as I, the said Benjamin Bailey, my exors, adñiors, 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 FOR MANUFACTURING
LOOPED 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 said Invention

page_text: and the manner in which the same is to be performed, are fully described
and 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 to a mode of constructing and working what are called
the presser bars of machinery used for making looped fabrics. It is well
known that the two classes of machinery which work with needles requiring
presser bars are framework knitting machines, which work with one thread
looped on many needles, and the successive loops of the same thread are
looped into the previously made fabric, as is well understood, and this is the
case whether the fabrics produced are plain stocking or knit fabric, or whether
the fabrics are made more or less open and ornamental. And the other class
of machines are warp machines, which vary in some of the details, according to
the fabrics produced thereby, by looping many warp threads with each other.
These two classes of machines are well known; it will therefore be unnecessary
to enter into any description thereof further than will be necessary in pointing
out how my improvements are to be applied thereto.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents so much of a vertical section of a framework knitting
or stocking machine as will enable me to describe my Invention. Figure 2
shews part of a front view of some of the same parts as are shewn at Figure 1.
The nature of the other views being written on the Drawings, it will not be
necessary to repeat them here. The machinery shewn is worked by means of
a rotatory axis. I have not, however, thought it necessary to shew the means
of giving motion to the various working parts of the machine, they forming no
part of my Invention, and the names of the ordinary parts which are shewn
are written on the Drawings. It will be seen that the sinkers are slightly
altered at the lower parts. a is the presser bar, which is carried by two arms
b, b; these two arms move on axes c, c, affixed to the ends of the carriage d,
which carriage with the working parts, move to and fro, as is well understood,
on plates e, so that the presser bar is carried to and fro with the carriage.
f is a spring, there being one at each end, supporting the presser bar and parts
connected therewith; g is a connecting rod, one at each end of the presser
bar, attached to an arm h, affixed to the spindle bar i. On the arm h is a
truck or roller, which bears against the cam j, affixed on the rotatory axis k.
All these parts are similar to those employed in like machines, they being only
varied to adapt them to the movements required for the novel mode of con-

page_text: structing and working the presser bar, which I will now proceed to describe.
The presser bar, as heretofore, works in front of the sinkers, but is so arranged
that a very short length of movement is required, and at the same time_the
parts of the presser bar are at all times between the sinkers, and in fact guide
and protect the sinkers from bending laterally, and it is these peculiarities of
constructing and working of presser bars of machinery making looped fabrics
that constitute the improvements secured under the above recited Letters
Patent. The presser bar is divided into as many parts 1, 1, as there are
needles, and so that one of the parts l enters and constantly works between two
neighbouring sinkers, whereby, on the one hand, the presser 1 for each needle
is guided in its work by the sinkers, and the sinkers are sustained and guided
by the pressers 1, 1, which will be found very important when working quickly;
and owing to the shortness of the motion required to the presser bar, aided by
the mutual guiding and supporting of the pressers and the sinkers, the speed
of the frame may be quickened with safety. The Drawing shews the pressers
cast in leads, so that they all press when any of them press; but this is not
absolutely necessary, as the workman may, if he desire it, for particular fabrics,
have the pressers / moveable in respect to each other, so that any of them may
be moved out of the way when the others are pressing.
1
Figures 3, 4, 5, and 6 shew the various positions the sinkers and pressers
assume in working a course, by which it will be seen that the pressers
never depart away from between the sinkers. I have not thought it necessary
to shew any parts of a warp machine, as a workman acquainted with such
machines, aided by the description herein given, will readily construct a
presser bar with separate pressers l, and work such bar in order to press on
the beards of the needles.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I do not claim any of the
parts separately, nor do I confine myself to the precise details, so long as the
peculiar character of my Invention be retained; but what claim is, the mode
of constructing and working presser bars of machinery for making looped fabrics,
as herein described.
In witness whereof, I, the said Benjamin Bailey, have hereunto set
my hand and seal, this Twenty-first day of August, in the year of our
Lord One thousand eight hundred and forty-four.
BENJAMIN (L.S.) BAILEY.
