"IMPROVEMENTS IN THE MANUFACTURE OF COMBS." [A communication from
abroad by Stanislas Henry Corbeels, of 10, Rue des Terres-fortes, Paris, in the
Republic of France.]
This Invention has for its object improvements in the manufacture of combs.
For this purpose I employ an artificial ivory known by the name of ivoride or
xyloidine. This material cannot for commerical purposes be made into combs by
the ordinary methods.
1
According to my Invention I employ circular saws to cut the teeth; the saws are
tempered to a suitable hardness, and are mounted on a shaft driven at a high
velocity. The plate of ivoride is fixed upon a carriage, and moved gradually up to
the saws until the teeth are cut to the full depth.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by

"IMPROVEMENTS IN THE MANUFACTURE OF COMBS." (A communication from abroad

France.)
This Invention has for its object improvements in the manufacture of combs.
For this purpose I employ an artificial ivory known by the name of ivoride or
xyloidine. This material cannot for commercial purposes be made into combs by
the ordinary methods.
:
According to my Invention I employ circular saws to cut the teeth; the saws
are tempered to a suitable hardness, and are mounted on a shaft driven at a high
velocity. The plate of ivoride is fixed upon a carriage and moved gradually up to
the saws until the teeth are cut to the full depth.
In order that the said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The annexed Drawing shows the apparatus which is employed in making combs
from ivoride in accordance with this. Invention.
J
The machine consists of a lathe driven either by the foot or in other convenient
manner; it is provided with a spindle carrying at its end a small circular saw. On
the bed of the lathe is a carriage, and upon the carriage there is a clamp for holding
the piece of ivoride, in which the teeth are to be cut to form a comb.
ง
The clamp is connected to the carriage by pivots or hinges, and when the piece 2
of ivoride has been made fast in the clamp by means of thumbscrews provided for
the purpose, the clamp is caused to turn about the pivots or hinges to bring the
plate of ivoride against the revolving cutter; this is done by the hand of the
workman who maintains a gentle pressure of the work on the cutter until the tootli
is cut to the full depth. The workman then turns back the clamp to be free of the S
cutter, and by any convenient arrangement allows the carriage to be drawn the
distance from tooth to tooth. The next 'tooth is then cut in a similar manner and
so on.

!
Having thus described the nature of the said Invention and the manner of
performing the same, I would have it understood that I claim, the inanufacture of 3
ivoride combs, substantially in the manner described.
In witness whereof; I, the said Charles Joseph King, have hereunto set my
hand and seal, this Thirteenth day of December, in the year of our Lord
One thousand eight hundred and seventy-seven.
