I, PETER JENSEN of 33 Chancery Lane in the County of Middlesex Fellow of
the Institute of Patent Agents do hereby declare the nature of said Invention for
IMPROVEMENTS IN COMBS FOR THE HAIR' a communication to me from abroad
by Franz Thormann and Leonhard von Bonhorst both of Wiesbaden Germany to
be as follows:-
Hair combs as heretofore made vizt in one piece are difficult to clean and become
useless and cannot be repaired when several of the teeth break off or split. The
object of this invention is to wholly overcome these defects, and with this view the
teeth are removable from the back or backbone of the comb for the purpose of
being replaced when injured.
The back bone of the comb is made of a section something like a U leaving a slot
all along the inner or under side. In the space thus formed the teeth are inserted
separately their head part being formed to suit the said space and being also formed
with a hole through, so that when the teeth are inserted in the space in the back
bone a continuous passage is formed through all the teeth, into which passage
a guide bar is inserted.
This guide bar consists by preference of three parts viz. two inner metallic bars
which together are a little less in length than the passage through the heads of the
teeth, and which each at the outer end is formed with a set off and a screwed part
and an outer part consisting of an India rubber loop or band which is passed right
round the sides and ends of the said two metallic bars thus holding them elastically
together. A knob formed nut on each screwed part serves to fix the guide bar in
position in the backbone.
The teeth may be of different thicknesses as heretofore, say one half thick, and
the other half thin.
The guide bar although by preference of a thin rectangular shape may also be of
oval round or other suitable section, and may be solid or tubular and in the latter
case pass through the head nuts or be screwed inside to receive little male screwed
heads. The inner metallic part may be made in one piece instead of two.

page_text: Instead of the India rubber band, a rubber cord may be used which is fixed to
end of each inner metallic bar, or a helical metallic spring may be substituted.
Although an elastic means of fixing the teeth is preferred as stated the teeth may
be fixed rigidly by a metallic or other suitable bar passing through their beads.
The slot through the backbone may be closed at one end, instead of being open
right through as stated. The essence of the invention is in all cases this that the
backbone of the comb is formed U shaped to receive the separate teeth in the
recess or slot so formed, and that the teeth are held therein, but so that they may
be detached and any one of them may be removed and replaced as required.
Dated this 12th day of August 1884.

I, PETER JENSEN of 33 Chancery Lane in the County of Middlesex Fellow of
the Institute of Patent Agents do hereby declare the nature of said Invention for
"IMPROVEMENTS IN COMBS FOR THE HAIR (A communication to me from abroad
by Franz Thormann and Leonhard von Bonhorst both of Wiesbaden Germany)
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:―
Hair combs as heretofore made viz in one piece are difficult to clean and become
useless and cannot be repaired when several of the teeth break off or split. The
object of this Invention is to wholly overcome these defects and with this view
the teeth are removable from the back or back bone of the comb for the purpose
of being replaced when injured.
Figure 1 of the accompanying drawings is half side elevation and half sectional
side elevation of a comb constructed according to this Invention. Figure 2 is
vertical section through same Figure 3 is half plan and half plan section on the
line x, y, Figure 1, and Figure 4 is a plan section through the appliance for
securing the teeth in place.
The back-bone a of the comb is made of a section something like a U leaving
a slot all along the inner or underside. In the space thus formed the teeth bare
inserted separately their head part being formed to suit the said space and being
also formed with a hole through, so that when the teeth are inserted in the space
in the backbone a continuous passage is formed through all the teeth, into which
passage a guide bar is inserted.
This guide bar consists by preference of three parts, viz, two inner metallic
bars c c¹ see especially Figure 4 which together are a little less in length than the
passage through the heads of the teeth, and which each at the outer end is formed
with a set off and a screwed part d and an outer part consisting of an india rubber
loop or band which is passed right round the sides and ends of the said two
metallic bars cc' thus holding them elastically together. A knob formed nut e on
each screwed part serves to fix the guide bar in position in the back bone.
The teeth may be of different thicknesses as heretofore say in one half of the
comb thick and in the other half thin.
The guide bar c c although by preference of a thin rectangular shape may also
be of oval, round or other suitable section, and may be solid or tubular and in the
latter case pass through the head nuts or be screwed inside to receive little male
screwed heads. Instead of the india rubber band, a rubber cord may be used
which is fixed to end of each inner metallic bar cc' or a helical metallic spring
may be substituted. The inner mettallic part may be made in one piece instead of
two c c¹ as here shown, and although an elastic means of fixing the teeth is
preferred as stated the teeth may be fixed rigidly by one metallic or other suitable
bar passing through their heads. The slot through the back bone may be closed
at one end instead of being open right through as stated. The essence of the
Invention is in all cases this that the back-bone of the comb is formed U shaped
to receive the separate tecth in the recess or slot so formed, and that the teeth are
held therein but so that they may be detached and any one of them may be
removed and replaced as required.
Having now particularly described and ascertained the nature of said Invention
and in what manner the same is to be performed I declare that what I claim as
the Invention communicated to me is
First: A comb with detachable teeth and consisting essentially of the hollow
back bone a and the teeth b which have heads corresponding with the interior of
the hollow back bone a and which are placed therein and held therein by means of
screws or other suitable means of fastening.

page_text: Second: In a comb with detachable teeth secured in a hollow back bone pro-
viding the teeth each with a hole through the head thus forming a passage right
through when in place.
Third: In a comb with detachable teeth secured in a hollow back-bone and
provided with holes through their heads thus forming a passage right through them
a guide passing right through such passage and made in one piece or made in two
pieces held together by a loop spring around them or a connecting spring between
them such guide being provided with end fastening or fastenings for holding the
teeth in place in the back-bone.
Fourth-The compound comb as shown on the drawings.
