County of Lancaster, Engineer and Machinist, for the Invention of
"IMPROVED MACHINERY TO BE EMPLOYED IN THE MANUFACTURE OF HEALDS
FOR LOOMS FOR WEAVING.'

Scaled the 10th December 1872, and dated the 12th June 1872.
PROVISIONAL SPECIFICATION left by the said Richard Walton Kenyon
at the Office of the Commissioners of Patents, with his Petition, on
the 12th June 1872.
I, RICHARD WALTON KENYON, of Accrington, in the County of
Lancaster, Engineer and Machinist, do hereby declare the nature of the
said Invention for "IMPROVED MACHINERY TO BE EMPLOYED IN THE MANU-
FACTURE OF HEALDS FOR LOOMS FOR WEAVING," to be as follows :—
These improvements relate to the manufacture of loom healds or
harness by the employment of machinery or mechanism. They relate
to and compose the manufacture of those known as single knot, which
require the use of varnish or other adhesive matter to hold them in place
when formed; and also to the manufacture of those known as double
knot, which retain their form without varnish.

page_text: In the mechanism for the single knot I employ a bobbin, shuttle, or
spindle, on which is wound one of the threads or yarns required, another
thread being wound on a bobbin carried by a disc wheel, as employed in
the ordinary hand machine. This shuttle, bobbin, or spindle is caused
to work backwards and forwards in a slide by a rod or lever, actuated by
a cam or tappet; or I make the shuttle or bobbin hollow, and cause it
to be worked backwards and forwards on a spindle, rod, or shaft. A
fork or semicircular loop former, by which the loop is formed, is carried
on the end of an upright shaft or spindle, sliding in a bracket. In this
shaft or spindle is cut one or more spiral or other grooves, as required,
and in the bracket is fixed a pin or screw, the point of which projects or
fits into the groove, and so a partial rotary motion is imparted to the
fork or loop former. This shaft or spindle is raised by means of a cam
or tappet and levers, and at the same time the partial circular or other
motion above referred to. The fork or loop former, when at its lowest
point, will allow the shuttle or bobbin to pass over it, carrying over it the
thread, which has first been tied to the rig band. This thread is carried
under the centre spindle, on which the eyes or loops are are formed,
and which serves to regulate their size by means of a finger fixed on the
disc wheel. The shaft or spindle carrying the fork or. loop former is
then raised by the cam or tappet and levers, and at the same time the
semicircular or other motion, as described, is imparted to it by the pin
or screw projecting or fitting in the groove. By these means the loop is
formed. A spindle or rod then pushes the shuttle or bobbin through the
fork on which the loop is, when it is seized by another lever, which
draws it past the rig band, from whence the yarn or thread is drawn
down by a catch or finger to the needle for the purpose of fastening to
the rig band. A catch lever prevents the bobbin or shuttle from
revolving while a finger draws the loop up tight. The eyes or loops are
taken off the spindle on which they are formed by a finger, which finger
also serves to support the rod on which the eyes or loops are passed
while the yarn is being passed under centre spindle. After the loop is
drawn tight the shuttle is again sent back, carrying the thread or yarn
over the fork or semicircle, and the whole process repeated.
In the mechanism for the double knot the shuttle is caused to pass
twice through the fork or semicircular loop former on which the loon is

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
WALTON KENYON, of Accrington, in the County of Lancaster, Engineer
and Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of June, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Richard Walton Kenyon, Her special licence
that I, the said Richard Walton Kenyon, my executors, administrators,
and assigns, or such others as I, the said Richard Walton Kenyon, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thercafter 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 "IMPROVED MACHINERY
TO BE EMPLOYED IN THE MANUFACTURE OF HEALDS FOR LOOMS FOR WEAVING," upon
the condition (amongst others) that I, the said Richard Walton Kenyon,
my executors or administrators, by an instrument in writing under my,
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Walton Kenyon, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Sheets of Drawings (that
is to say) :-
These improvements relate to the manufacture of loom healds or
harness by the employment of machinery or mechanism. They relate
to and compose the manufacture of those known as "single knot," which
require the use of varnish or other adhesive matter to hold them in place

page_text: when formed; and also to the manufacture of those known as "double
knot," which retain their form without varnish.
In the mechanism for the "single knot "I employ a bobbin, shuttle, or
spindle, on which is wound one of the threads or yarns required, another
thread being wound on a hobbin carried by a disc wheel, as employed in
the ordinary hand machine. This shuttle, bobbin, or spindle is caused
to work backwards and forwards in a slide by a rod or lever actuated by
a cam or tappet; or I make the shuttle or bobbin hollow, and cause it
to be worked backwards and forwards on a spindle, rod, or shaft. A
fork or semicircular loop former, by which the loop is formed, is carried
on the end of an upright shaft or spindle, sliding in a bracket. In this
shaft or spindle is cut one or more spiral or other grooves, as required,
and in the bracket is fixed a pin or screw, the point of which projects or
fits into the groove, and so a partial rotary motion is imparted to the
fork or loop former. This shaft or spindle is raised by means of a cam
or tappet and levers, and at the same time the partial circular or other
motion above referred to. The fork or loop former, when at its lowest
point, will allow the shuttle or bobbin to pass over it, carrying over it
the thread, which has first been tied to the "rig band." This thread is
carried under the centre spindle, on which the cyes or loops are formed,
and which serves to regulate their size by means of a finger fixed on the
disc wheel. The shaft or spindle carrying the fork or loop former is
then raised by the cam or tappet and levers, and at the same time the
semicircular or other motion, as described, is imparted to it by the pin
or screw projecting or fitting in the groove. By these means the loop is
formed. A. spindle or rod then pushes the shuttle or bobbin through the
fork on which the loop is, when it is seized by another lever, which
draws it past the rig band, from whence the yarn or thread is drawn
down by a catch or finger to the needle for the purpose of fastening to
the rig band. A catch lever prevents the bobbin or shuttle from
revolving while a finger draws the loop up tight. The eyes or loops are
taken off the spindle on which they are formed by a finger, which finger
also serves to support the rod on which the eyes or loops are passed
while the yarn is being passed under centre spindle. After the loop is
drawn tight the shuttle is again sent back, carrying the thread or yarn
over the fork or semicircle, and the whole process repcated.

page_text: twice through the fork or semicircular loop former on which the loop is
made, or two of the said loop formers may be employed.
Such being the nature and object of this my said Invention, I will
now proceed to describe the same in detail, and in order that the
Invention may be clearly understood, I have hereunto annexed three
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.
Fig. 1 is a side elevation of the working parts of my Invention; Fig. 2
is a cross section of the same through liné A, B, of Fig. 1; Fig. 3 is a
plan view of Fig. 1; Figs. 4, 5, and 6 are details drawn full size.
A, A, is the frame of the machine; B is a cross head or piece fixed to
the frame, and carrying the bobbin C, the latter being received and held
in the shuttle C¹ (see Figs. 4 and 5). On this bobbin one of the threads
to be used is wound, another thread being wound on the bobbin D,
carried by the disc wheel D'. This disc and bobbin are similar to those
employed in the ordinary hand machine heretofore employed. The
shuttle C¹ and the bobbin C therein are caused to work backwards and
forwards, or "to and fro," in the slide E by means of the rod or lever E¹,
actuated by the cam or tappet E. At F is shewn a fork or semicircular
loop former, by which the loop is formed, and on which is a flange F¹.
F2 and Fare fingers or hooks which engage with the thread from the
bobbin C, and on being raised by means of the levers F, F³, and
cams F, F, the finger F being by its lever and cam caused to act
slightly in advance of or carlier than the finger F³, so as to avoid too
much tension or stress on the thread. The thread now being around
the fork F, the latter will, by means of the lever G and cam G¹ and
spindle G³, to which the hook is attached, be lowered in its support or
boss G. The said spindle is chased or screwed so as to engage with a¨
pin passed through one side of the boss, that on the said spindle being
lowered a partial rotation of the spindle and hook will take place,
thereby crossing the thread, whereon the shuttle C₁ and bobbin C will,
by means of the slide piece E³, actuated by means of the lever E' and
cam E' pass through the hook F and the eye of the loop thread around
the same, the said shuttle and bobbin being drawn forward by the
hooked finger E, secured to the slide piece E', which is operated by
means of the levers E³ and E', E, and tappet E². The fingers F and F³

page_text: and
will meanwhile by means of their respective levers F', F³,
cams F, F, be lowered, and so disengage the thread, which will thereon
be drawn tight by means of the lever H and finger H', operated by the
tappet H³, whereon the thread will be caught by the nib on the lever J,
and lifted on to the needle J' for the purpose of securing it to the rig
bands, the lever J being operated by means of the swell J³, so that the
lever J is moved in and out of position as the passing of the shuttle
requires. The hooked finger or catch lever E is pointed, as shewn at X,
Fig. 3. This portion enters the teeth of the catch whicel X' on the
bobbin C, and prevents the same revolving whilst the thread is being
drawn tight by means of the finger H', previously referred to. The eyes
of the healds are thus formed in succession, and as formed each is
deposited on the end of the pointed rod K, whereon the sliding hollow
spindle K advances by means of the incline K³, revolving with the
disc D', and pushes the eyes as formed on to the rod K, as in the
ordinary hand machine. The pusher K¹ is drawn clear of the point of
the rod K, so as to allow space for the thread to pass between the two
by means of the spiral spring K³. The rod K is made slightly less in
diameter at the point where the eyes are first deposited, and on the
pusher K advancing them to the enlarged diameter of the said rod; the
equal size of the eyes is thus ensured. L is a support for the rod K, and
is caused to lower or descend during the time an eye is being pushed
forward by the pusher K', whercon it again ascends and prevents the
eyes slipping forward. The raising and lowering of this support is
accomplished by means of the lever M and cam N on the shaft P (sec
Figure 7.)
Having thus fully described the nature and particulars of this my
Invention, together with the manner in which the same is to be or may
be performed or carried into practical effect, I would have it understood
that I claim as my Invention,—
Firstly. The fork or semicircular loop former, operated as herein
described and illustrated.
Secondly. The fingers for holding the thread on the fork or semi-
circular loop former, as herein described and illustrated.
Thirdly. The shuttle, together with the slides and hooked finger E³,
as and for the purpose hiercin fully described and illustrated in the
Drawings.

page_text: Fourthly. The rod K when of varying diameter, as shewn, together
with the support L and finger H', for purposes herein fully described.
Fifthly. The catch X on the hooked finger E, and the catch wheel X¹
on the bobbin C, for the purpose of preventing rotation of such bobbin
whilst the loop is being drawn up, as fully described and illustrated.
Lastly. The finger J, as and for the purpose herein described and
illustrated.
In witness whereof, I, the said Richard Walton Kenyon, have
hereunto set my hand and seal, this Tenth day of December,
in the year of our Lord One thousand eight hundred and seventy-
