PROVISIONAL SPECIFICATION.
Improved Apparatus Applicable to Double Locker Lace Machines.
We HENRY BODEN, and WALTER BODEN, both of 36 London Street, Derby, Lace
Manufacturers, do hereby declare the nature of this invention to be as follows:-
In the lower driving shaft of a double locker lace machine we secure a toothed beve
wheel gearing into a larger bevel wheel secured on a shaft revolving in bearing
brackets attached to the framing of the machine.
The shaft carries a motion cam plate, a clutch box and a slotted plate, in each slot
an arm is capable of adjustment, the outer end of each arm projects so as to engage
with one or other of a series of teeth which project from a pattern plate revolving on
an axle carried by a lever rocking on an axle secured to the framing of the machine.
The lever is caused to rise and fall by a stud or truck it carries, being operated by the
motion cam plate, above the revolving pattern plate is a truck carried by the lower
arm of a right angled rocking lever, having its upper arm hinged to one of the usual
thread guide bars.
We employ as many rocking levers and pattern plates as there are thread guide
bars to be operated.
We are thus enabled to produce a greater variety of patterns than heretofore.
COMPLETE SPECIFICATION.
Improved Apparatus Applicable to Double Locker Lace Machines..
We HENRY BODEN and WALTER BODEN both of 36 London Street Derby Lace
Manufacturers do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an end view of our improved apparatus looking from the right end
of the double locker lace machine to which it is applicable. Figure 2 shows a front.
view of the same; the corresponding parts in each Figure are lettered alike. In
addition to the two thread guide bars usually employed to make traversed net in a
double locker lace machine we employ other thread guide bars, the number varying
according to the pattern required, two guide bars only are shown in the drawings,
each bar being traversed by the following means.
On the lower driving shaft A of a double locker lace machine we secure a toothed
bevel wheel B, gearing into a larger bevel wheel B' secured on a shaft B² revolving
in bearing brackets attached to the framing of the machine, the shaft B2 carries a

motion cam plate B³ on each side of which two arms C, and Care adjusted.
outer end of arm C projects so as to engage with one or other of a series of teeth on
one half of the circumference of a plate C² which is secured to the side of a pattern
plate D, and the outer end of each arm C engages with one or other of a series of
teeth on a plate secured to the side of the pattern plate, the pattern plates revolve
on an axle carried by a lever D' which rocks on an axle D2 carried by the framing of
the machine.
The lever D' carries a stud or truck on its lower side, operated by the motion cam
plate B beneath it, causing the lever D¹ and pattern plates D, to rise and fall, above

page_text: each pattern plate is a truck carried by the lower arm of a right angled lever D³
which rocks on an axle D also carried by the framing of the machine.
The upper ends of the levers D³ may each be hinged to a thread guide bar, or each
bar may be traversed by the following means. Above the levers D³ aro two flat bars E
which slide upon supporting brackets secured to the framing of the machine, the
upper bar is provided with brackets which carry a back thread guide bar E' and the
lower bar with brackets which carry a front thread guide bar E each of the bars E,
carry a short arm E³ projecting downwards and pressing upon a truck D' capable of
adjustment on the upper end of the lever D³ the left end of each of the bars E is
provided with a spring in the usual way which holds the arm E³ close to the track.
We employ as many sets of motion cam plates B³ arms and C₁ toothed
plates C3 and C3 pattern plates D, and right angled truck bearing levers D' as there
are additional thread guide bars to be operated.
We are thus enabled to produce a greater variety of patterns on the traversed net
made in double locker lace machines than heretofore.
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 we claim
is:-
The construction and employment of improved apparatus for producing patterns on
traversed net made in double locker lace machines substantially as described and
illustrated in the accompanying drawings.
