PROVISIONAL SPECIFICATION.
An Improvement in Combs used in Machines for Making Lace.
I, JOHN JARDINE, Machinist, of Raleigh Street Nottingham do hereby declare the
nature of this invention to be as follows:-
From an ordinary comb I take away from one or both sides of it-a portion of
the metal of which the comb is made.
The part of the comb which is thus reduced in thickness so as to form a recess or
clearance is that part held fast by the casting metal and the part immediately
above it.
This improved comb has a much greater elasticity sideway thus preventing damage
from wrong-gating.
The recess also allows the dirt, fluff & threads forced into the combs by the action of
the machine, to escape without causing damage by their obstruction.

COMPLETE SPECIFICATION.
An Improvement in Combs used in Machines for Making Lace.
1, JOHN JARDINE, Machinist, of Raleigh Street, Nottingham, 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,
reference being had to the accompaning drawings and to the letters and figures
marked thereon, that is to say:-
Heretofore great inconvenience has been experienced by reason of the combs used
in lace-frames being so constructed as to be so rigid and inflexible that should two
carriages enter one gauge, or opening between two of the teeth, they become firmly
locked therein, and not only cause serious obstruction to the working, but likewise
damage to the machine.
Now, according to my invention, I construct the combs in such manner, as is about to
be described, that these evils are entirely and effectually obviated.
From an ordinary comb I take away, from one or both sides thereof, a portion of
the metal of which the comb is made. The part of the comb which is thus reduced
in thickness so as to form a recess or clearance is that part held fast by the casting
metal and the part immediately above it. This improved comb has a much greater
lateral elasticity than heretofore, whereby damage from wrong gating is prevented.
This recess also allows any dirt, fluff, and threads which may be forced into the combs,
by the action of the machine, to escape without causing damage or inconvenience by
their obstruction.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the same with reference to the accompanying
drawings.
Fig. 1 is a plan, Fig. 2 a side elevation, Fig. 3 an underside view, and Fig. 4 a
front elevation of a comb-lead constructed according to my invention. Fig. 5 is a
cross section on the line A, B. of Fig. 2 showing the portions of the comb from which
the metal has been removed.
a, a, are the combs held, as is usual, in the casting metal b. c is the portion of
the comb from which the metal has been removed, thereby reducing the thickness of
it at the required parts and rendering the same flexible. But instead of removing the
metal on both sides of the comb as shewn, it may, if preferred, be removed from one
side only.

page_text: That portion (or portions) of the metal which is required to be reduced in thickness,
may be removed by a milling or other suitable machine, or if preferred by hand filing.
In the latter case the teeth of the comb are held in a holder or clamp provided with
an adjustable block for raising that portion of the comb which is to be acted upon by
the filc.
Having now particularly described and ascertained the nature of my said inven-
tion and in what
claim is
manner the same is to be performed, I declare that what I
1. The construction of combs, for use with lace-machines, in which a portion of the
metal either on one or on both sides of the comb, and in proximity to the casting
metal, is reduced in thickness whereby a recess or clearance is formed between each
of the combs, thus rendering said combs flexible laterally, substantially as described
and for the purposes set forth.
2. A comb for use with lace machines, having a recessed portion, or portions, such
as c, at that part held by and immediately above the casting metal, as described and
shown by the accompanying drawings.
