DRYING YARN, WOVEN FABRICS, AND OTHER MATERIALS." A communication
from abroad by Messieurs Tulpin Brothers, of Rouen, Franco, Machine
Makers.

PROVISIONAL SPECIFICATION left by the said William Sumner at the Office
of the Commissioners of Patents on the 13th March 1877.

PROVEMENTS IN APPARATUS FOR DRYING YARN, WOVEN FABRICS, AND OTHER
MATERIALS." A communication from abroad by Messieurs Tulpin Brothers, of
Rouen, France, Machine Makers.
This improved apparatus may be used for drying warp yarns after they have
been sized in the ordinary sizing machine; or for drying woven fabrics or paper, or
any other substance or material, and it consists of any convenient number of steam
chests placed either horizontally, vertically, or diagonally, between which the yarn
or other material is caused to travel slowly, being guided over rollers placed near
the ends of the chests, the spaces between the chests forming any number of
compartments, according to the nature of the material to be dried and the degree of
drying required.
The chests are all supplied with.steam from a main pipe, and another pipe is
provided to carry off the water of condensation; a safety valve is also applied to
the supply pipe. A current of air is forced or drawn through the spaces between
the steam chests to evaporate and carry off the moisture, and this current of air is
produced by a fan, or by a steam jet or other equivalent means.

WILLIAM SUMNER, of Manchester, in the County of Lancaster, Merchant. " IM-
PROVEMENTS IN APPARATUS FOR DRYING YARN, WOVEN FABRICS, AND OTHER
MATERIALS." A communication from abroad by Messieurs Tulpin Brothers, of
Rouen, France, Machine Makers.
This improved apparatus may be used for drying warp yarns after they have
been sized; or for drying woven fabrics or paper, or any other substance or material,
and it consists of any convenient number of steam chests placed either horizontally,
vertically, or diagonally, between which the yarn or other material is caused to
travel slowly, being guided over rollers placed near the ends of the chests, the
spaces between the chests forming any number of compartments, according to the
nature of the material to be dried and the degree of drying required.
The chests are all supplied with steam from a main pipe, and another pipe is
provided to carry off the water of condensation; a safety valve is also applied to
the supply pipe. A current of air is forced or drawn through the spaces between
the steam chests to evaporate and carry off the moisture, and this current of air is
produced by a fan, or by a steam jet or other equivalent means.
And in order that this Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings,
which represents an elevation partly in section of the improved drying apparatus.
The upper and lower parts of the Drawing are supposed to represent the two halves
of the machine, the vertical line a, a, at the right-hand side of the upper part of
the Drawing corresponding to the line b, b, at the left-hand side of the lower part
of the Drawing.
The Drawing represents a machine for sizing and finishing warps to which my
improvements are applied; c, c, are two of the ordinary beams from which the yarn
to be sized is unwound; and d is the trough containing the size and the usual
immersion and squeezing rollers; c, c, e, are three or other convenient number of
steam chests, which are contained in the box f; the steam chests are placed
horizontally by preference, but in some cases they may be placed vertically or
diagonally. The chests e are all supplied with steam from a main steam pipe,
and each chest is in communication with another pipe to carry off the water
of condensation; a safety valve is applied to the steam supply pipe to prevent
accidents. When the warp has been sized in passing through the trough & it enters
the box f, and is carried over the upper steam chest e, and around the roller g, from
whence it passes back between the upper and middle steam chests to the roller h,
from which it traverses between the middle and lower steam chests out of the box f
to the roller ; the warp is then taken over and under the ordinary lease rods to the
measuring roller j, and from thence it passes to and is wound on the warp beam
in the usual manner. A current of air is forced or drawn through the box f and
from between the steam chests e by means of the fan l, the current of air produced
by the fan being in the contrary direction to that of the warp or other material that
is passing between the steam chests; this current of air carries off the moisture that
is evaporated by the heat.
It is evident that instead of drawing the air through the box fit may be forced
through and instead of using a fan to produce the current of air the same object
may be effected by a steam jet, or by other equivalent means.
This improved drying apparatus may be used for drying woven and other fabrics,
or paper, or other materials, and the distance between the steam chests can be varied
according to the material to be dried.
Having thus stated the nature of this Invention. as communicated to me by
Messieurs Tulpin Brothers, and described the manner of performing the same, I declaro
that I claim, the improved drying apparatus described, consisting of any convenient

page_text: number of steam chests surrounded by a box, through which currents of air are
forced or drawn by a fan or other equivalent.
In witness whereof, I, the said William Sumner, have hereunto set my hand
and seal, this Sixth day of September, One thousand eight hundred and
seventy-seven.
