PROVISIONAL SPECIFICATION left by the said Richard Chamberlain
and Thomas Wagstaff at the Office of the Commissioners of Patents,
with their. Petition, on the 24th October 1874.
WC, RICHARD CHAMBERLAIN and THOMAS WAGSTAFF, both of
Manchester, in the County of Lancaster, do hereby declare the nature
of the said Invention for "Improved ApparATUS FOR FORMING LOOPS OR
EYELETS UPON WIRE," to be as follows:-
This Invention is designed for forming loops or eyelets of any desired
size, and at any required intervals upon wire, which wire with the loops
or eyelets so formed may be used for making wire screens by passing plain
wires at right angles through the loops, and also for other useful and
ornamental purposes.

page_text: The coil of wire to be operated on is carried on a stud mounted in the
side or face of a wheel or disc, which is capable of revolving and which
is driven at a suitable speed by gearing either by power or in connection
with a winch handle. In the central boss of this wheel or disc is a hole
through which passes a pin or rod which is of such a thickness as will
form the loop or eyelet of the desired size, and such an alternate motion
is imparted to this pin or rod by means of an excentric crank, cam, or other
similar device as will cause it to be alternately thrust forward so as to
project from the boss and be withdrawn therein at stated intervals. The
end of the wire from the coil passes this pin and is affixed to a wheel or
pulley to which an intermittent revolving motion is given by means of a
ratchet wheel or otherwise, such motion taking place at the time that
the pin or rod above named is within the boss and ceasing when the pin or
rod is projected.
The action is as follows:-Supposing the wheel or disc carrying the
coil of wire to be revolving, if the pin or rod is projected from the contre
of the boss the wire will be caused to make one turn or coil round this pin
or rod, thus forming a loop or eyelet. The pin then descends, the wheel or
pulley to which the end of the wire is attached then makes a portion of
a revolution and draws the wire on a stated distance. This motion then
ceases, the pin is projected, another loop or cyclet formed, and so on
alternately.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Richard Chamberlain and Thomas Wagstaff in
the Great Seal Patent Office on the 23rd April 1875.

page_text: Richard Chamberlain and Thomas Wagstaff, our executors, admini-
strators, and assigns, or such others as we, the said Richard Chamberlain
and Thomas Wagstaff, our executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, usc, excrcise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN APPARATUS FOR FORMING LOOPS OR EYELETS
UPON WIRE," upon the condition (amongst others) that we, the said
Richard Chamberlain and Thomas Wagstaff, our executors or admini-
strators, by an instrument in writing under our, 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 Scal Patent
Office within six calendar montlis next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Chamberlain and Thomas
KNOW
Wagstaff, do hereby declare the nature of the 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
Drawings (that is to say) :-
This Invention is designed for forming loops or cyclets of any desired
sizo, and at any required intervals upon wire, which wire with the loops
or eyelets so formed may be used for making wire screens by passing
5 plain wires at right angles through the loops, and also for other useful.
and ornamental purposes.
The coil of wire to be operated on is carried on a stud mounted in the
side or face of a wheel or plate, which is capable of revolving and which
is driven at a suitable speed by gearing either by power or in connection
) with a winch handle. In the central boss of this wheel or plate is a hole
through which passes a pin or rod, which is of such a thickness as will
form the loop or eyelet of the desired size, and such an alternate motion
is imparted to this pin or rod by means of an excentric, crank, cam, or
other similar device as will cause it to be alternately thrust forward so
3 as to project from the boss and be withdrawn therein at stated intervals.
The end of the wire from the coil passes to this pin round a wheel or
pulley to which an intermittent revolving motion is given by means of a

page_text: ratchet wheel or otherwise, such motion taking place at the time that
the pin or rod above named is within the boss, and ceasing when the pin
or rod is projected.
Such being the nature and object of our said Invention, we will now.
proceed to describe more in detail the manner in which the same is to be
or may be performed or carried into practical effect, and in order that the
same may be clearly understood we have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures and
letters of reference corresponding with those in the following explanation
thereof :-
Fig. 1 is a plan view of the apparatus; Fig 2, a side view; and Fig. 3, a
partial sectional view of the same.
a, a, is the table of the machine, in the centre of which is a hollow stud
b, b, carrying the revolving plate c, c, which is driven by a pair of bevil
wheels d, d, actuated by a winch handle on the fly wheel c, c. The
revolving plate c, c, carries on one arm the bobbin or coil of wire f, f, to
be operated upon, and also on the other arm a grooved pulley g, g, round
which the wire passes on its way to the pin h, h. The wire is held
against this pulley g, g, and prevented from getting slack by means of a
small bowl i upon a break lever k, k, to which a weight 1, 1, is attached by a
cord. On the axis of the grooved pulley g, g, is fixed a ratchet wheel
m, m, provided with a spring catch n, n. The pin h, h, is drawn down
at the required moment by means of a tappet o, o, attached to one of
the bevil wheels d, d, (see Fig. 3), acting on a projection p, and it is
raised up again as soon as released by the coiled spring q, q. The extreme
end of the wire is attached to a drum or pulley ", r, on a shaft 8, 8, at
the other end of which is keyed a similar pulley t, t, round which is
coiled a cord, to the other end of which a weight n is attached.
The action of the machine is as follows:-Supposing the wheel or
plate c, c, carrying the coil of wire f,f, to be revolving in the direction
of the arrow, if the pin or rod h, h, is projected from the centre of the
boss v, v, the wire will be caused to make one turn or coil round this pin
or rod, thus forming a loop or cyelet. The pin / is then drawn down by
the tappet o, o, the tail end of the spring catch n, n, comes against a
fixed pin wc, which momentarily releases the ratchet wheel m, m, and
allows the weight u to draw the wire on a certain distance. The spring
catchn, n, then falls in gear with the ratchet wheel m, m, the piu h, h, is -

page_text: again projected, and.the wire commences to make another loop or cyclet,
and so on alternately. It will be obvious that by a slight modification,
this apparatus may be caused to make the loops or eyelets alternately
upon each side of the wire.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be performed
or carried into practical effect, we wish it to be understood that we claim
as our Invention, the particular arrangement of apparatus herein-before
described and exhibited on the Drawings'annexed, for forming loops or
eyelets upon wire or any mere modification or imitation thereof,
constructed and operating in substantially the same or a similar
manner.
In witness whereof, we, the said Richard Chamberlain and Thomas
Wagstaff, have hereunto set our hands and scals, this Twenty-
second day of April, in the year of our Lord One thousand eight
hundred and seventy-five
RICHARD CHAMBERLAIN. (L.S.)
