PROVISIONAL SPECIFICATION.
A New Instrument, Rule, or Gauge for Measuring and Testing the
Quality of Lace made on a Lever's Lace Machine.
FREDERICK PLUMB 8 Wellington Square Park Side Nottingham Commercial
Traveller, do hereby declare the nature of this invention to be as follows
An instrument for calculating at a glance the quality of all kinds of lace made
on the Levers lace machine.
The instrument is made of any kind of metal or wood.
I give a drawing of the instrument made of metal & mounted on wood A & B
are two pieces of metal at right angles to one another. The piece A is divided
into sections & each section is divided into smaller sections which represent two.
motions of the machine the larger sections represent each 16 motions of the lace
machine.
I have taken altogether 24 large sections of 16 motions or 384 motions in all,
but there no limit to the no. of motions I can go. C is an index finger fastened by
the screw in the slot E. It rests on the point D (which starts the first motion on.
the strip A) & points to any figure on the strip B, it is between the point D & any
figure on the strip B that the lace is placed to be tested.
EXAMPLE.
A lace pattern measuring say 14 inches & containing in that space 144 motions,.
would be placed opposite the number of motions, viz. 144 at right angles to it, then-
place the index finger, (letting it touch the point D) on the lace exactly 1 inches.
in length, and glance down the index finger, you will see it has registered nearly
24, that means, that, that piece of lace is nearly 24 inches to the rack, a rack ís
1920 motions of the machine.
The strip B at right angles to A is calculated for every 2 inches to the rack &
can again be subdivided.
I have only gone up to 30 inches to the rack but can go as high as wanted.
I have also another strip parallel to B and running at right angles to A, which
is marked in inches & tenths of an inch, this strip slides up and down A, it keeps:
the lace in proper position for testing, as any deviation from the right angle would
alter the index.
With this instrument, buyers can test the quality of their goods much quicker
and with greater accuracy, draftsmen and makers can make the measures from
this instrument for their workmen to work with, far more reliable than ever they
have done before.

COMPLETE SPECIFICATION.
A New Instrument, Rule, or Gauge for Measuring and Testing the
Quality of Lace made on a Lever's Lace Machine.
FREDERICK PLUMB, 8 Wellington Square, Park Side Nottingham, Commercial
Traveller, 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 :-
An instrument rule or gauge for calculating at a glance the quality of lace made:
on a
Lover's lace machine

page_text: The instrument can be made of any kind of metal or of wood.
I adopt the drawing "left with the Provisional Specification
explanation of the same.
and give
A and B are two pieces of metal (this style being mounted on a wood board) at
right angles to one another.
The piece A is divided into sections and those sections are subdivided into
smaller sections which represent every two motions of the lace machine each larger
section represents sixteen motions of the lace machine.
I have taken altogether 24 sections of sixteen motions or 384 motions in all
but there is no limit to the number of motions I can go. C is an index finger
fastened to the wood board by the screw over and in the slot E, it rests on the
point D which starts the first motion on the strip A, when the index finger C.rests
on the point D and points to any figure on the strip B, the figure thus indicated
shows the quality of the lace.
EXAMPLE.
As an example of the above I take a lace pattern measuring 2 inches in length
and having in that length 240 motions of the machine by placing the lace (or its
equivalent a measure of 24 inches) on the board at right angles to the strip A and
opposite the number of motions viz. 240 then place the index finger at the extreme
edge of the lace (or its equivalent,) just the 2 inches from the strip A. then see
that the index finger C touches the point D on the strip A, glance down the index
finger to the strip B you will see at a glance it has registered the number 22, that
means that, that identical piece of lace is 22 inches to the rack, a rack being
1920 motions of the lace machine.
The strip B at right angles to A is calculated every 2 inches to the rack but can
again be subdivided into inches & fractions of an inch. In my drawing I have only
gone up to 30 inches to the rack but can go as high as required.
I have also another strip parallel to B which is ruled in inches and fractions of an
inch, this strip slides up and down A. It is for the purpose of keeping the lace
or its equivalent always at right angles to A also it obviates the necessity of
placing a rule on the instrument.
The same instrument, rule or gauge can also be applied to lace made on the
lace curtain machines, the plain net machines and the fast and other warp machines.
This instrument rule or gauge can also be made in shape or form of a pocket rule,
to fold up so that it may be carried about in a small pocket.
This instrument is not only useful in testing lace when it is made, but by
placing a design on the board (having previously placed the index finger on the
figure required on the strip B and allowing it to touch the point D) you will find
out the number of motions which will be required in any design to give the number
of inches to the rack as denoted on the strip B.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A simple, ready and effective means of calculating the quality of all kinds of
lace made on lace machines.
2. An easy and true method of determining the number of motions to be put in
any design of lace to make that design the quality required.
