Year: 1880

page_text: LETTERS PATENT to Friedrich Hermann Felix Engel, Civil Engineer and
Patent Agent, in the City of Hamburg, Germany, for an Invention of
"IMPROVEMENTS IN COMBS OF VULCANIZED INDIA RUBBER, HORN, AND
CELLULOID." A communication from Theodor Schnitzlein, Manager of the
New York Hamb Gummiwaaren-Fabrik, of the City of Hamburg, Germany.
PROVISIONAL SPECIFICATION left by the said Friedrich Hermann Felix
Engel at the Office of the Commissioners of Patents on the 23rd June 1880.
FRIEDRICH HERMANN FELIX ENGEL, Civil Engineer and Patent Agent, in the
City of Hamburg, Germany. "IMPROVEMENTS IN COMBS OF VULCANIZED INDIA
RUBBER, HORN, AND CELLULOID." A communication from Theodor Schnitzlein,
Manager of the New York Hamb Gummiwaaren-Fabrik, of the City of Hamburg,
Germany.
This Invention relates to certain improvements in combs of vulcanized india
rubber, horn, and celluloid, and has for object to give greater durability, lightness,
and elasticity to the teeth and body of such combs, and prevent the breaking away
of the teeth as has hitherto been liable to be the case.
The combs made according to this Invention are made with a concave groove or
curve extending towards the foot of the teeth and diminishing in width with the
prolongation of the teeth. The base of such combs are formed for the purpose of
strengthening the teeth with a conically or concavely tapering broad base, by
which construction a very strong and elastic tooth is obtained.
Along the groove, at the base of the teeth of these combs, when moulded, a strip
or strips of metal, such as spring steel, is or are laid along in each side of the
moulds and become imbedded in the comb. The groove formed at the base
of the teeth will in the case of horn combs be planed out by a plough planing
tool

the said Friedrich Hermann Felix Engel in the Great Seal Patent Office on
the 23rd December 1880.
FRIEDRICH HERMANN FELIX ENGEL, Civil Engineer and Patent Agent, in the
City of Hamburg, Germany. "IMPROVEMENTS IN COMBS OF VULCANIZED INDIA
RUBBER, HORN, AND CELLULOID." A communication from Theodor Schnitzlein,
Manager of the New-York-Hamb Gummiwaaren, of the City of Hamburg,
Germany.
This Invention relates to certain improvements in combs of vulcanized india rubber
or other vulcanizable gums, horn, celluloid, and other known material used for the
manufacture of combs, and has for object to give greater durability, lightness, and
elasticity to the teeth and body of such combs, and prevent the breaking away of the
teeth as has hitherto been liable to be the case. Combs heretofore made have
generally been furnished with teeth of either straight or convex outer profilation.
The combs made according to this Invention are made with a concave groove or
curve extending towards the foot of the teeth, and diminishing in width with tho
prolongation of the teeth. The base of such combs are formed for the purpose of
strengthening the teeth with a conically or concavely tapering broad base, by
which construction a very strong and elastic tooth is obtained.
The accompanying Sheet of Drawings illustrates this Invention. Figs. 1 and 4
are combs formed after this improved construction; Figs. 2 and 5 respectively
illustrate the new shape or profilation of the teeth and body of the combs; whilst
Figs. 3 and 6 respectively illustrate the old shapo of the teeth and body of the
comb. It will be seen that far less material is required for the new construction,
and that greater elasticity must ensue from it.
Having now described the nature and particulars of the said Invention, I
claim,―
The construction of the teeth of combs of vulcanized india rubber or vulcanizable
gums, horn, celluloid, and other material used for the manufacture of combs with a
concave groove or curve extending towards the foot of the teeth and diminishing
in width with the prolongation of the teeth, as herein set forth and shown by the
Drawings.

In witness whereof, I, the said Friedrich Hermann Felix Engel, have hereunto
sot my hand and seal, this Eighteenth day of Decomber, in the year of:
our Lord One thousand eight hundred and eighty.
