Frame Smith and WILLIAM WYLIE of Stewarton, in the County of Ayr, North
Britain, Scotch Bonnet Manufacturer do hereby declare the nature of the said
invention for "IMPROVEMENTS IN THE MANUFACTURE OF SCOTCH BONNETS AND
IN THE MECHANISM EMPLOYED THEREFOR" to be as follows:-
:-
This Invention, which relates to improvements in the manufacture of Scotch
Bonnets and in the mechanism employed therefor, is a further development of the
Invention for which Provisional Protection was granted to us the said Alexander
Goold and William Wylie N° 3678 A.D. 1884, and has for its object to facilitate
the manufacture of that part of such bonnets known as the-" peak," and the said
mechanism also ascertains the number of gussets which have been worked in the
said bonnets, as set forth in the aforesaid Provisional Specification.
In carrying this Invention into practice, upon the framing of the machine at any
suitable position there is arranged a disc or wheel which is shapod with two, three
or more projections. Upon the shaft to which this disc or wheel is fixed there is
secured a ratchet wheel and spring pawl attachment for preventing tho said disc or
wheel from turning round in one direction after having been turned in the opposite
direction by means of a hand levor secured to the disc or wheel, or to the shaft
carrying the same. At the end of the guide bar or bars upon or in which the
swing thread carriers slide, and adjacent to this disc or wheel, there is provided an
arm carrying an anti-friction roller, which is pressed or drawn against the edge of
the disc or wheel, by means of a spring secured to any suitable fixed part of the
frame.
At every stroke of the said swing thread carriers, the end of the slide, to which
they are secured, abuts against the end of the slide or stop carrying the arm before
mentioned, and thereby the travel of the said thread carriers is limited, according
as the anti-friction roller is caused to bear against a projection or the bottom of
a recoss between the said projections on the disc or wheel. The arm carrying the
anti-friction roller is fitted, by means of a slotted connection, to the slide or stop
upon which it is mounted, so that it is rendered capable of adjustment, according
as the "peak" of the bonnet to be worked is required narrower or broader, or the
bonnet to be worked is required larger or smaller. The inner pressor plate of this

page_text: mechanism is operated by the disc or wheel herein before mentioned, by means of
a slotted piece secured to the slide or stop, in the slot of which a pin, connected to
the said inner presser plate, is capable of moving in a direction at right angles to
the motion of the said slide or stop. Or a pin may project downwards from the
slide or stop and project' into a slotted piece secured to the presser plate. The
outer presser plate is operated by similar connections with the "leaf cam" referred
to in the Provisional Specification N° 3678 A.D. 1884.
As a means for ascertaining the number of gussets which have been worked in
Scotch Bonnets by the mechanism set forth in the aforesaid Provisional Specification,
there is secured to the outer sliding pressor plate of such mechanism a pawl of any
suitable construction, and upon the presser bar of the said mechanism there is
provided a ratchet wheel. At each revolution of the "leaf cam "" hereinbofore
referred to, the ratchet wheel herein last mentioned is caused to rotate through
a known distance, so that any number of such distances passed through by the said
ratchet wheel, indicates the number of gussets worked in the bonnets. A spring is
provided to prevent the ratchet wheel from running back, and it may also be
provided with an index and counter of any suitable construction.

page_text: We, ALEXANDER GOOLD, of Hawick, in the County of Roxburgh, North Britain,
Frame Smith and WILLIAM WYLIE, of Stewarton, in the County of Ayr, North
Britain, Scotch Bonnet Manufacturer do hereby declare the nature of the said
invention for IMPROVEMENTS IN THE MANUFACTURE OF SCOTCH BONNETS AND IN
THE MECHANISM EMPLOYED THEREFOR and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
Our Invention, which relates to improvements in the manufacture of Scotch
Bonnets and in the mechanism employed therofor, is a further development of the
invention described in our Complete Specification N° 3678 A.D. 1884. and has for
its object to facilitate the manufacture of that part of such bonnets known as the
"peak," and the said mechanism also ascertain number of gussets which have
been worked in the said bonnets.
In carrying our Invention into practice, on the framing of the machine at any
suitable position thereon, there is arranged a disc or wheel which is shaped with
two, three or more projections.-Upon the shaft to which this disc or wheel is fixed,
there is secured a ratchet wheel and spring pawl attachment for preventing tho
Said disc or wheel from turning round in one direction after having been turned in
the opposite direction by means of a hand lever secured to the disc or wheel, or to
the shaft carrying the same. At the end of the guide bar or bars upon or in
which the swing thread carriers slide, and adjacent to this disc or wheel, there is
provided an arm carrying an anti-friction roller, which is pressed or drawn against
the edge of the disc or wheel, by means of a spring secured to any suitable fixed
part of the frame.
At every stroke of the said swing thread carriers, the end of the slide, to which
they are secured, abuts against the end of the slide or stop carrying the arm before
mentioned, and thereby the travel of the said thread carriers is limited, according
as the anti-friction roller is caused to bear against the projection or the bottom of
a recess between the said projections on the disc or wheel.. The arm carrying the
anti-friction roller is fitted, by means of a slotted connection, to the slide or stop
upon which it is mounted, so that it is rendered capable of adjustment, according
as the "peak" of the bonnet to be worked is required narrower or broader, or the
bonnet to be worked is required larger or smaller. The inner presser plate of this
mechanism is operated by the disc or wheel heroinbefore mentioned, by means of
a slotted piece secured to the slide or stop, in the slot of which a pin, connected to
the said inner presser plate, is capable of moving in a direction at right angles to the
motion of the said slide or stop. Or a pin may project downwards from the slide
or stop and project into a slotted picce secured to the presser plate. The outer
presser plate is operated by similar connections with the "loaf cam" referred to in
the aforesaid Complete Specification N° 3678, A.D. 1884.
As a means for ascertaining the number of gussets which have been worked in
Scotch Bonnets by the mechanism set forth in the aforesaid Complete Specification
there is secured to the outer sliding presser plate of such mechanism a pawl of any
suitable construction, and upon the presser bar of the said mechanism there is
provided a ratchet wheel-At each revolution of the "leaf cam" hereinbefore
referred to, the ratchet wheel hereinlast mentioned is caused to rotate through
a known distance, so that any number of such distances passed through by the said
ratchet wheel, indicates the number of gussets worked in the bonnets. A Spring is
provided to prevent the ratchet wheel from running back and it may also be
provided with an index and counter of any suitable construction,
.

page_text: In order that our said Invention may be properly understood and readily carried
into effect we will now proceed to describe the Drawing hereunto annexed.
This Figure of Drawing represents in front elevation a portion of a "stocking
frame" fitted with mechanism constructed according to, and constituting our presont
Invention.
In carrying our present Invention into practice, wo arrange the disc or wheel a,
upon the framing of the machine or preferably to rotate upon the pin or short
shaft b, secured to the bar c.-This disc or wheel is shaped with two, three or more
projections d, the disc or wheel represented upon the annexed drawing being formed
with three such projections. Upon the shaft b, on which the disc or wheel a, is
carried, there is also provided, preferably at the back of, and secured to, the said
disc or wheel, the ratchet wheel e, which is represented in dotted lines upon the
annexed Drawing. With the teeth of this ratchet wheel e, the spring pawl or
catch f. engages, so that after the said disc has been rotated in the required direction
it is secured against a return motion and held in the position so arrived at, until
required to be again rotated. The spring pawl or catch f, is secured to the bar c,
and the disc or wheel a, is rotated by the hand lever g, which is secured to the face
of such disc or wheol. At the end of the bar c, upon or in which the swing thread
carriers h, are guided, and adjacent to the disc or wheel a, there is provided the
armi, carrying the anti-friction roller j, which is pressed or drawn against the edge
of the disc or wheel a, by means of the spring, which is secured at its one end to
the fixed bracket Z, and at its opposite end to the pin m,-The arm i, is secured by
a slotted or adjustable connection n, to the plate o, into the projection p, of which,
the pin m, is secured. The plate o, is free to slide longitudinally upon the bar c, it
being supported thereon, by the nut q, the stud of which passes through the
slot To the inner end of the plate o, and at the upper part thereof, is secured
the catch 8, while at the lower part, the slotted bracket t, is secured. The catchs,
is so arranged that, at the end of the stroke of the swing thread carriers h, tho
spring u, shall impinge upon and pass over the said catch, and offer sufficient
resistance to maintain the swing thread carriers, in the position so arrived at,
until such time as they are required to make their return stroke, when the power
applied overcomes the resistance offered by the catch 8, and spring u, and leaves
the said carriers 7, free to complete their return stroke. The spring u, is secured
to the bar v, supporting the carriers h, which are secured thereto by bolts or other
equivalent means. The slotted bracket t, engages with the pin w, which is secured
to the presser plate x, and by this means is free to transmit longitudinal motion to
the said plate. This presser plate x, is free to slide longitudinally by reason of its
slotted connection y, with the presser bar z, and the radial motion which is
imparted to the said plate x, and bar z, similarly provided for by the slot within
the bracket t, being formed in the direction of such radial motion. In place of the
brackett, being secured to the sliding plate o, and the pin w, to the presser plate x,
we may arrange the pin wu, to be secured to the plate o and projecting downwards
into the slotted bracket t, which, under such construction would be secured to the
presser plato x-The outer presser plate a', is operated through connections similar
to those herein last described by the "leaf cam referred to in our Complete
Specification No 3678 A.D. 1884.
"
The operation of the mechanism is as follows:-At every stroke, that is to say,
at every return stroke of the swing thread carriers h, the end of the bar v, to
which they are secured, abuts against the end of the plate o, carrying the arm i,
and thereby the travel of the said thread carriers h, is limited. The limit of such
travel is determined by the position of the disc or wheel a, relatively with that of
the anti-friction roller j, that is to say, whether the said wheel a, is turned so that
a projection d, is presented to the said roller, or whether it is so turned that the
roller j, is drawn against its edge beween such projections. The extent of travel of
the thread carriers h, thus under control is. such as is taken up by the formation
of the "peak" of the Scotch bonnets being worked upon the machine, so that
when the roller j, bears against a -projection d, of the wlieel a, the peak is not

page_text: being worked, and when the said roller j, bears against the wheel a, between the
projections d, the thread carriers are allowed their full travel and consequently, at
the time, work the said "peak." The arm i being adjustable upon the plate o,
adinits of the bonnets to be worked upon the machine, being made smaller or
larger as required.

As a means for ascertaining the number of gussots which have been worked in
Scotch bonnets by the mechanism described in our aforesaid Complete Specification
No 3678 A.D. 1884. we secure the pawl b', to the outer sliding presser plate a',
operated by such mechanism, and upon the presser bar z, we provide the ratchet
wheel c. At each complete revolution of the." leaf cam described in our aforesaid
Complete Specification and therefore at the working of each gusset, the ratchet
wheel c', is caused by the pawl b', to rotate through a known. distance, so that
any number of such distances passed through by the said ratchet wheel c¹, indicates
the number of gussets worked in the bonnets. The spring d¹, engages with the
teeth of the ratchet wheel c', and prevents it from running back, and the said
ratchet wheel may be provided with an index and counter of any suitable con-
struction, which may be contained in a locked case and be so arranged as to
indicate both the number of gussets worked in a bonnet, and the number of
bonnets so worked, and by these means provide a check against the operator.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
wo claim is
First, In mechanism for the manufacture of Scotch Bonnots, the means for
limiting the travel of the swing thread carriers h, for either the working, or non-
working of the "peak" of such bonnets; consisting of the disc or whoel a, with
its projections d, ratchet wheel e, spring catch f, sliding plate o, with the arın i,
adjustable thereon, anti-friction roller j. spring k, and projection p, and their
attachments all substantially as and for the purposes hereinbefore set forth with
reference to the annexed drawing or the mechanical equivalents of all or any of
the said parts.
Second, In mechanism for the manufacture of Scotch bonnets, the means for
ascertaining the number of gussets worked therein consisting of the pawl b',
ratchet wheel c, and spring catch d¹, and their attachments substantially as
hereinbefore set forth with reference to the annexed drawing.
