page_text: We JOSEPH JEFFERSON, MORDECAI JEFFERSON, CORNELIUS JEFFERSON and
LAZARUS JEFFERSON, all of Bradford in the County of York, Machine Makers
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS EMPLOYED FOR DRYING FIBRES, YARN, AND FABRICS
to be as follows:-
"
This Invention though mainly designed for drying slivers of wool after "back
washing" is applicable to yarn, yarn sizing, and piece drying machines.
In machines for drying fibres, yarn, or fabrics, where steam drying cylinders are
used, such as "back washing" machines, slasher sizing machines, as heretofore
constructed glands are employed, to prevent escape of steam, the tight packing of
the glands necessitates increased expenditure of power to revolve the cylinders, and
by reason of the whole interior of the cylinders being charged with steam, there is
great loss through condensation, and inconvenience through accumulation of water
of condensation.
We dispense with the stuffing glands and with revolving steam cylinders, and
by reason of improved construction of steam heated cylinders, and heating
apparatus, hereinafter described, effect great saving in quantity of steam employed.
The machine may be run at higher speed and with relatively less expenditure
of power.
In the construction of machines for purpose aforesaid, according to this our said
Invention, we employ a stationary steam jacket, consisting of a hollow cylinder,
bolted to the framing of the machine, the cylindrical steam jacket is enclosed by
an outer revolving cylinder, over or under which the slivers, yarn, or pieces are
passed, and within the drying frame under each drying cylinder, is a segmental
steam jacket, radial with the outer diameter of the revolving cylinders, and these
radial steam jackets have holes cast through them. Below the radial jackets, are
other horizontal steam heated jackettings the space between the two, forms a
drying and air heating chamber. A fan is employed to discharge air into the

page_text: drying chamber whence the heated air passes through the holes in the segmental
steam jackets, to the cylinders under and over which the slivers, yarn, or pieces
are being passed and dryed.
Any desired number of cylinders may be employed, the outer cylindrical casings
being provided with teeth, or spur wheels, and gearing with each other, or
otherwise caused to revolve. The steam jackettings are connected by steam supply
and discharge pipes that the steam may pass from cylindrical jackets, to the radius
jackets, thence to the bottom or horizontal jackets, the whole being enclosed by
folding or sliding doors.

Fig. 2 is an elevation of the opposite side of the machine, showing the pipes and
taps for supply of steam to the cylinders also illustrates the arrangement of rollers
and washing trough for "backwashing" slivers of wool."
Fig. 3 is a right hand elevation of the machine.
Fig. 4 is a section of the steam cylindrical jacket, outer drying cylinders thereon,
radial steam jackets and horizontal steam jackets in relative position.
Fig. 5 is a section of steam cylindrical jacket, bolted to side framing of machine,
showing outer toothed or geared cylinder, end cap or supporting disc and rod.
Fig. 6 is sectional elevation of the cylinder and jacket.
Figs. 7, 8, 9 and 10 are views of jacket and cylinder (enlarged scale).
Figs. 11 and 12 are plan and end elevation of perforation radial steam jackets.
At 1, 1 are the hollow cylindrical steam jackets secured by the bolts 2, 2, 2 to
the side frame 3; and 4 is the outer cylinder or casing heated by the steam in
jacket 1, and having teeth 5 so that the several outer drying cylinders or
casings gear with each other and revolve in the direction shewn by arrows
being driven by the pinion 6 (see Fig. 2)—The outer cylinder 4 is supported on
the steam jacket 1 and held in position by the end plate or disc 7 carried by the
adjustable upright rod 8-The said rod 8 also serves as bolt for the hinges 9. 9 of
the doors 10. 10-11. 11 are the holding latches-At 12. 12 are the supports for
the upright rod 8-At 13 are the radial steam jackets these have perforations
formed therein by short lengths of pipes passed through them (see Fig. 4)-15 are
the horizontal steam jackets placed under the radial jackets, and 17 is a fan for
circulating the hot air.
The supply of steam to the several steam jackets is shewn at Figs. 2 and 3,
wherein 18 is the main inlet comprising a "six way valve," 19 the inlet pipe
and 20 the distributing pipes-At 21 are the circulating pipes by which the steam
from the cylinder jackets 1 is passed to the valve 22, thence by pipe 23 to the

page_text: radial jacket 13 and by pipe 24 therefrom to the other radial jacket 13 and by
pipe 25 to the end radial jacket 13, thence by pipe 26 to the horizontal jacket 15,
and by pipe 27 to the next jacket 15, thence by pipe 28 to end jacket 15 to a
discharge pipe-At 29 is the sliver yarn or piece showing its course through the
rollers and over the drying cylinders or casings and steam jackets-The interior of
revolving cylinders 4 is lubricated by way of the hand hole 30 and the pipes 31, 31
passed through the jacket 1.
It will be understood that the radial steam jackets 13 and the horizontal steam
jacket 15 may be used in combination with a steam charged cylinder of the
ordinary construction.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is:
The combination in a machine for purposes aforesaid of the fixed steam
jackets 1 having revolving drying cylinders or casings 4 substantially as set forth.
The combination in a machine for purposes aforesaid of the cylindrical radial,
and horizontal steam jackettings combined and connected with each other
substantially as shewn and set forth.
The radial steam jackets 13 horizontal steam jackets 15 in combination with a
revolving steam cylinder for purposes herein set forth.
