JULES, FRANÇOIS-XAVIER FAUVELLE, of No. 10, Boulevart Bonne-Nouvelle, Paris,”
in the Republic of France, Comb Manufacturer. "AN IMPROVEMENT IN THE MANU-.
FACTURE OF COMBS."
The object of my Invention is to give greater strength to the teeth and back
of combs, whether made of tortoiseshell, india-rubber, horn, or any of the:
materials of which combs are usually made, and whatever the shape or size of the
comb.
i
"I propose to effect this object by incorporating or embedding in the material of
which the comb is manufactured a piece of metal or other material of greater
resistance than the body of the comb, and so placed, that after having cut the teeth
of the comb, "each tooth will contain, in as much of its length as may be deemed
necessary, a portion of this strip of metal or other suitable material, which will
also extend from end to end of the comb at the base of the teeth, or not quite
to the end, as
as may be preferred, and as far-into the back of the comb as may be
desired.
Pa
In applying my Invention, for example, to a tortoiseshell comb, I propose to pro-
ceed as followsIn preparing the pieces of tortoiseshell to be united by heat and
pressure in the ordinary way, I leave sufficient space for embedding the metal or
strengthening material, so that after the union has taken place the whole forms
one body. I then cut the teeth and finish the comb in the ordinary way, or in
any suitable manner.

4th December 1877.
JULES FRANÇOIS-XAVIER FAUVELLE of No. 10, Boulevart Bonne-Nouvelle, Paris,
in the Republic of France, Comb Manufacturer. "AN IMPROVEMENT IN THE MANU-
FACTURE OF COMBS."
The object of my Invention is to give greater strength to the teeth and back of
combs, whether made of tortoiseshell, india-rubber; horn, or any of the materials of
which combs are usually made, and whatever the shape or size of the comb, or the
use for which it is intended.
Hitherto it has only been sought to strengthen the back of combs, but it fre-
quently happens that the teeth break at the foot, and by my improvement the
comb is at the same time consolidated or strengthened both in the back and in its
teeth. I effect my object by inserting, incorporating, or embedding in the material
of which the comb is manufactured a piece of metal or other material, of greater
resistance to breakage than the body of the comb, and relatively soft, zinc for.
example, and so placed that after having sawn or cut the teeth, of the comb, ench
tooth will contain, in as much of its length as may be deemed necessary, a portion
of this strip of metal or other suitable material, which will also extend
longitudinally from end to end of the comb at the base of the teeth, or not
quite to the end, as may be preferred, and as far into the back of the comb as
may be desired.
In applying my Invention, for example, to a tortoiseshell comb, I may proceed
as follows: In preparing the pieces of tortoiseshell to be united by heat and
pressure in the ordinary way, I leave sufficient space for inserting or embedding
the strip or band of metal or other strengthening material, so that after
this union has taken place the whole forms one body. I then saw or cut
the teeth and finish the comb in the ordinary way, or in any suitable manner.
In making combs of hardened india-rubber, I may embed or incorporate the
band of strengthening metal or other material with the india-rubber previous to
submitting it to the hardening process.
The accompanying Sheet of Drawing represents a comb made according to my
Invention.
Figure 1 is a longitudinal view, partly in section; and Figure 2, a cross section,
of two pieces, bands, or plates of tortoiseshell or other material of which it is
intended to form the comb. Between these two pieces a, a, is inserted a small plate
or strip b of zinc, or other soft metal, or of metal or material relatively soft; these 4
two pieces a, a, and the strip b, are united or welded together in the ordinary
manner of uniting tortoiseshell, or in any suitable manner, and then the whole is
sawn or cut to the desired "depth to form the teeth, as shown, Figures 3 and 4. In
this operation the consolidating or strengthening strip or plate b strengthens at the
same time the back c of the comb and the foot of the teeth d (as shown in dotted

page_text: lines, Figure 3). The comb thus made offers great resistance to breakage both in
the back and in the teeth.
As above stated the strip or plate 6 may be of zinc or other metal; it may also be
made of any material possessing a certain amount of rigidity, such for example as
pasteboard, papier-mâché, hardened india-rubber, or hardened wood.
Having now described and ascertained the nature of my said Invention and in
what manner the same is or may be performed, I claim as the Invention secured to
me by the herein-before in part recited Letters Patent, the manufacture of combs of
all kinds, and of all shapes with teeth strengthened or consolidated by means of a
strip or small plate of metal or other material inserted between the two pieces,
bands, or plates of the material which forms the comb, the whole united or welded
together, then shaped and divided, the effect of this Invention being to strengthen
at the same time the back and the foot of the teeth of the comb, substantially as
herein-before described, and shown on the accompanying Sheet of Drawing.
In witness whereof, I, the said Jules François-Xavier Fauvelle, have hereunto
set my hand and seal, this Third day of December, in the year of our Lord
One thousand eight hundred and seventy-seven.
