HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
APPARATUS FOR TREATING CARBON FILAMENTS," a communication to me from
abroad by Charles. G. Perkins of New York United States,
The invention relates to an oil reservoir provided with a tap for the reception
of a metallic pipe which is made fast thereto and extending therefrom at a
suitable distance, at which point it is connected with a glass tube having two
globular enlargements integral therewith, the said tube is provided with stop cocks
opposite the said globular enlargements. One of the globes is provided with a
hollow projection having a soft rubber pouch mounted thereon. The farther end
of the glass tube is mounted with a second soft rubber pouch with its opposite
end mounted on a metallic pipe having a stop cock thereon; the said pipe is
connected with another leading into a chamber wherein carbon filaments are
placed for their final treatment.
The invention also relates to placing the oil reservoir within a metallic drum or
case provided with means for supporting the said oil reservoir and for the
accommodation of an oil lamp or other suitable device for heating said reservoir to
a very high temperature.
The invention relates to an oil reservoir made of glass or other suitable material
provided with a tubular extension at its base, said extension is connected with a
metallic tube which passes into a chamber arranged within a furnace. The tubular
extension is provided with a stop cock which shuts the oil off or on, also with a
secondary tapering tube which begins at the walls of the tubular extension on the
interior thereof just a little below the stop cock, and extends downward at any
suitable distance therefrom. The tubular extension is also provided with a
projecting tube on the side thereof, said projection enters the base of a bulb or
condenser having a tubular projection at the top thereof and extending therefrom
to a suitable distance; this latter portion is provided with a series of bulbs or
condensers arranged on the under side thereof with stop cocks arranged on the'
lower extensions of the bulbs. The extreme end of the tube having the bulbs.

filaments are placed for final treatment.
The invention relates to the method of hydro-carbonizing carbon filaments with
hydro-carbon fumes which is first prepared in a heated chamber with a tubular
outlet through which the fumes pass to the heated chamber wherein the carbon
filaments are placed to be hydro-carbonized.
The invention relates to a carbonizing box provided with a perforated plate
resting against the wall of said box a little above its base and having a feed pipe
extending therefrom to a suitable distance above where it is joined with an upright
glass tube provided with an oil feeding contrivance similar to the one for which I
have applied for Letters Patent.
The invention relates to a secondary glass tube connected with the upright
tube, said secondary tube enters the side of a bulb provided with a tubular
extension on the bottom thereof said extension having a stop cock. The upper
part of the bulb is provided with a tubular extension provided with a gas jet
on the end thereof, said extension also having a tube projecting from the side
thereof.
The invention relates to arranging a series of perforated carbonized discs
within a carbonizing box and placing between each disc a number of carbon
filaments to receive their final treatment
