PROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR COMBING WOOL AND
OTHER FIBROUS SUBSTANCES.' (A communication from abroad by Alphonse Pollet,
Achille Pollet, and Samuel Pegler, all of Tourcoing, in the Department of Nord, in
the Republic of France.)
The object of this Invention is for the purpose of heating and retaining the heat
of combs, known as segment combs, flat or inclined nacteur combs, such as are used
in machines known as the square motion or Holden's combs.
The arrangement consists in formning a groove or recess in the body of the steam
box, and in this groove the pins are caused to travel or pass in such manner that
they are protected from external air, moving as they do in the heated air contained
in the groove or recess.
The following are the effects produced by this arrangement:-The pins in the
combs attain a higher degree of temperature and retain that temperature during
the operation of the machine, effecting thereby a great improvement in the working
of wool and other fibrous substances.

PROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR COMBING WOOL AND

The object of this Invention is for the purpose of heating and retaining the heat
of combs, known as segment combs, flat or inclined nacteur combs, such as are used
in machines known as the square motion or Holden's combs.
The arrangement consists in forming a groove or recess in the body of the steam
box, and in this groove the pins are caused to travel or pass in such manner that
they are protected from the external air, moving as they do in the heated air
contained in the groove or recess.
The following are the effects produced by this arrangement:-The pins in the
combs attain a higher degree of temperature and retain that temperature during
the operation of the machine, effecting thereby a great improvement in the working
of the wool and other fibrous substances.
And in order that the Invention may be more completely understood reference
is given to the accompanying Drawings, and to the letters and marks thereon.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a cross section through steam box or chest; Fig. 2, a part plan of the
same, looking at the top, on a reduced scale, with the improvements applied.
a is the steam box or chest, b is one of the segments of the circle, and c, the pins
on the segment. d is the groove or recess formned by applying a flange e on the
outer edge of the circular steam chest or box a. In this grooved the pins c travel,
and being covered in by the segments b they are protected from the external air,
and move along in the heated air contained in the groove or recess d. The flange e
may be cast on the steam box or chest « or otherwise secured thereto in such a
manner as to form the herein before mentioned groove or recess & for the purpose of
heating and retaining of combs, known as segment combs, flat or inclined nacteur
combs, such as are used in machines known as the square motion or Holden's
comb.
Having thus described the nature of the said Invention, and described with the
aid of Drawings how the same may be carried into practice, I would have it under-
stood that I do not limit myself to the precise limits, details, or configuration of the
parts herein expressed and shewn, as the same may be varied or modified without
departing from the nature of the said Invention, but what I claim and desire to
be secured by Letters Patent is,―
The arrangement, construction, and application of groove or recess & applied to
the steam chest or box of wool combing machines for the purpose of heating and
retaining the heat of combs known as segment combs, flat or inclined nacteur
combs, such as are used on machines known as the square motion or Holden's
combs, substantially as hercin set forth.
In witness whereof, I, the said John Charles Walker, have hereunto set my
hand and seal, this Eleventh day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
