T
PROVISIONAL SPECIFICATION left by the said Ephraim Allcock
Jones and John Allcock Jones at the Office of the Commissioners
of Patents, with their Petition, on the 15th March 1875.
We, EPHRAIM ALLCOCK JONES and JOHN ALLCOCK JONES, both of
Middlesbrough, in. the County of York, do hereby declare the nature of
our said. Invention for "IMPROVEMENTS IN ROTARY PUDDLING FURNACES, AND
IN APPARATUS OR MEANS EMPLOYED IN CONNECTION THEREWITH," to be as
follows:-
Our Invention relates to improvements in rotary puddling furnaces
and to apparatus or means to be employed in connection therewith, for
supplying water for circulation around the furnace, and consists, firstly,

page_text: in admitting water intermittently to the space between the casings of
the furnace (when the furnace is composed of two casings) which are.
practically water-tight by various modes or contrivances, one mode being
by means of scoops or bent pipes attached at intervals round the outer
casing so that on the rotation of the furnace the open ends or mouths of
these scoops, or pipes will successively dip into water contained in a
tank underneath. Inside these scoops, or pipes, or ducts are valves
opening inwards to the water space and so operated by weighted levers
or other suitable devices that they are caused to open only when the
scoop is near to or has attained its highest point in its rotary movement
and to shut after the water taken up by the scoop has passed them into
the water space. Or in lieu of a tank water may be supplied to the
scoops or pipes through a valve or cock arranged externally to tho
apparatus.
In some cases a coil of pipes of an annular space or duct may be
formed round the outside of the revolving furnace, one end of the said
coil or duct communicating with the water space, whilst its outer or
open end is formed in the shape of a scoop for receiving the water in a
similar manner to that already described.
'Another plan for the admission of water to the water space is by
means of buckets arranged at intervals around and attached to the out-
side of the outer casing. In the bottoms of these buckets are spring
valves opening inwards to the water space and mounted on spindles
provided at their outer ends with rollers or wheels. Arranged externally
to and vertically over the furnace is a water valve or cock fitted to the
end of a water supply pipe and furnished with a pendant triangular
projecting ring or surface. The spindle of this water valve or cock is
fitted with a lever, at the end of which is a weight which tends normally
by its gravity to fall and thereby close the said valve or cock. To the
outer casing, close against and corresponding in number to the buckets,
are attached projecting lugs or tappets, which on the rotation of the
furnace strike successively against the weight on the end of the lever of
the water valve or cock, and the weight mounting the said lugs or
tappets causes the water valve or cock to be opened which allows the
water to flow from the supply pipe into the buckets, at the same time a
the rollers or wheels at the outer ends of the spindles of the bucket or
spring valves successively strike and roll over the under side of the
triangular projecting ring, thereby depressing and so opening the said
:

page_text: valves successively and admitting the water to the space between the
two casings. On passing each projecting lug the weight on the end of
the lever drops into its normal position and closes the water valve or
cock, thereby preventing any further flow of water therefrom, at the
same time the roller on the spindle of the bucket valve has left the
surface of the triangular projection and the valve is then closed by its
spring and prevents any escape of water from the water space.
In some cases we admit a continuous stream of water to the spaco
between the two casings and maintain the space full of water by means
of rings or ducts composed of any suitable material and arranged in the
following manner:-The revolving furnace has formed on it as part of
its outer casing, or attached to its exterior, a ring made by preference
(although it may be modified to other shapes) of the shape in cross
section of what is known as channel iron, around which ring there is
placed a stationary ring corresponding in sectional form to the other
ring (or it may be of other than channel section) but inverted. The
latter ring is made of suitable dimensions to fit either within the channel
of the revolving ring or outside the same so as to leave a space between
the two for the admission of water, which is supplied thereto by means
of a pipe or hose and thence passes through an opening into the water
space between the two casings of the revolving furnace.
In order to prevent leakage in the apparatus leather, india-rubber, or
other suitable packing is employed in the interior of the inner ring, and
the rings may be fitted together so as to leave a space between the
vertical sides of the channel of the two rings for the reception of a coil
of packing, which is maintained in its place by means of a band of
metal or by means of an annular gland which may be pressed upon the
packing, or by both in combination if desired.
Another means of admitting a continuous stream of water is by
having a ring, duct, or channel either attached to the outside of the
rotary furnace and composed of one or more pieces, or forming part of
the outer casing of the furnace. This ring, duct, or channel, or the
casing of the furnace, as the case may be, is provided with an open slot
er passage running round the whole of its circumference, in which a
pipe or water. communication above the furnace is inserted, which slot
or passage being covered or protected around its whole circumference
y a band of leather, or india-rubber, or other suitable substance to

page_text: prevent the escape of the water. By means of this arrangement no
leakage or escape can take place at the top where the pipe is inserted
between the packing and the ring or duct except when the furnace is
full of water.
A further means for admitting the water to the water space consists
in the employment of a flexible tube which is caused to wind or coil
around the revolving furnace, one end of such tube being in communi-
cation with the water supply, and the other end in communication with
thic water space. The tube is wound or coiled round a drum, through or
to the axis of which that end of it which is connected with the water
supply passes or is attached (a suitable gland and stuffing box being
provided) in such a manner that the tube becomes uncoiled from the
drum by the motion of the revolving furnace and coiled round the
latter. When the whole or nearly the whole length has been unwound
from the drum the motion of the revolving furnace is reversed, whereby
the tube becomes uncoiled therefrom; the length being simultaneously
taken up by the drum as it is uncoiled from the revolving furnace, so
that the water is thus supplied continuously through the coil to the
water space of the revolving furnace.
Secondly. In effecting the egress of the water and air from the water
space of the rotary furnace by means of pipes, channels, or ducts, one or
more of which are coiled round the outside of the outer casing and
communicate at one end with the water space. Or if preferred they
may be coiled in the water space, one end passing through the outer
casing. By means of these coils of pipes no water can escape from the
water space except by evaporation, overflow, leakage, steam or air
pressure.
Thirdly. In connecting the water pipes which are cast in the bodies
of the rings, or fitted in after the rings are cast (which rings are attached.
to the ends of the rotary furnace), at their external ends outside the
furnace with the water space between the casings by means of branch
pipes or connecting pieces.

TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, EPHRAIM
ALLCOCK JONES and JOHN ALLCOCK JONES, both of Middlesbrough, in
the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of March, in the year
of our Lord One thousand eight hundred and seventy-five, in the 38th
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Ephraim Allcock Jones and John Allcock Jones,
Her special license that we, the said Ephraim Allcock Jones and John
Allcock Jones, our executors, administrators, and assigns, or such
others as we, the said Ephraim Allcock Jones and John Allcock Jones,
our executors, administrators, or assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN ROTARY PUDDLING FURNACES, AND IN APPARATUS OR MEANS
EMPLOYED IN CONNECTION THEREWITH," upon the condition (amongst others)
that we, the said Ephraim Allcock Jones and John Allcock Jones, our
executors or administrators, by an instrument in writing under our
hands and scals, or under the hand and scal of one of us, should par-
ticularly describe and ascertain the nature of tho said Invention, and
in what manner tlie same was to be performed, and cause the same
to be filed in the Great Scal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Ephraim Allcock Jones and John
Allcock Jones, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings, and to the letters and figures
marked thereon, that is to say :-
Our said Invention relates to the construction of rotary puddling
furnaces, and to apparatus or means to be employed in connection

page_text: therewith for supplying water for circulation around the furnace, and it
consists more particularly in the employment of certain improved modes
or contrivances for admitting water to the water chamber or space
between the casings of the furnace (when the furnace is composed of
two casings practically water-tight).
According to one arrangement we admit a continuous stream of water
to the water chamber or space between the two casings, and maintain
the chamber or space full of water by means of rings or ducts composed
of any suitable material and applied in the following manner :—The
rotary furnace has formed on it as part of its outer casing, or attached
to its exterior, a ring made of any suitable form, but by preference of
the shape in cross section of what is known as channel iron, around
which ring there is placed a stationary ring corresponding in sectional
form to the other ring, but inverted, or of any other convenient shape,
so as to form between them an annular duct or channel for the passage
of the water. The latter ring is made of suitable dimensions to fit either
within the channel of the revolving ring or outside the same, so as to
leave a space between the two for the admission of water, which is
supplied thereto by means of a pipe or hose, and thence passes through
an opening into the water space between the two casings of the rotary
furnace.
In order to prevent leakage in the apparatus leather, india-rubber, or
other suitable packing, is employed in the interior of the inner ring, and
the rings may be fitted together so as to leave a space between the
vertical sides of the channel of the two rings for the reception of a coil
of packing, which is maintained in its place by means of a band of
metal, or by means of an annular gland, which may be pressed upon the
packing, or by both in combination if desired.
Another means of admitting a continuous stream of water consists in
the employment of a ring duct or channel, either attached to the outside
of the rotary furnace and composed of one or more pieces, or forming
part of the outer casing of the furnace, which ring duct or channel, or
the casing of the furnace, as the case may be, is provided with an open
slot or passage extending around the whole of its circumference, in
which a pipe or water communication above the furnace is inserted, such
slot or passage being covered or protected around its whole circumference
by a band of leather or india-rubber, or other suitable substance, to

page_text: prevent the escape of the water. By means of this arrangement no
leakage or escape can take place at the top where the pipe is inserted
between the packing and the ring or duct, or the casing of the furnace,
except-when the furnace is full of water.
Either of the foregoing means may be employed for conducting the
water out of the furnace or for emptying the furnace.
A further modification of our Invention consists in admitting the
water to the water space by means of a flexible tube which is caused to
wind or coil around the rotary furnace, with the water space of which
one end of the tube communicates, whereas the opposite end of the tube
which is in communication with the water supply is wound or coiled
round a drum, through or to the axis of which its extremity passes or is
attached, a suitable gland and stuffing box being provided in order to.
maintain a tight joint. The tube becomes uncoiled from the drum by
the motion of the rotary furnace and coiled round the latter; but when
the whole or nearly the whole length has been unwound from the drum
the motion of the rotary furnace is reversed, whereby the tube becomes
uncoiled therefrom, the length being simultaneously taken up by the
drum as it is uncoiled from the rotary furnace, so that the water is thus
supplied continuously through the coil to the water space of the rotary
furnace.
And in order that our said Invention may be fully understood wo
shall now
proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed two Sheets of
Drawings, the same letters of reference indicating corresponding parts
in all the Figures.
Figure 1, Sheet 1, of our Drawings represents a transverse section of
a rotary, puddling furnace fitted with rings. for the admission of water
according to one mode of carrying out our Invention.
:
Figure 2 is a corresponding longitudinal section of a portion of the
furnace; and Figure 3 is an enlarged sectional detail, showing, the con-
struction and arrangement of the rings. A is the water chamber or
space, which is formed by the inner casing B and the outer casing C,
to the latter of which we attach by means of screwed tubular con-
nections a, a, and nuts a metal ring D, which consequently revolves with
the furnace, a ring or layer 6 of any suitable elastic or yielding material
being if desired interposed between the ring D and the casing C. The

page_text: ring D is cast or otherwise formed with annular flanges b', 6', so as to
produce a trough or channel in cross section, in which there is placed a
stationary ring E of nearly a similar form to the ring D, but inverted,
the ring E being by preference constructed in segments bolted together
The two rings D, E, form between them an annular chamber or
space F for the admission of water, which is supplied thereto by a
pipe c' screwed into the ring E, and thence passes through the tubes
a, a, into the water chamber A.
at c.
An annular flexible ring d, of a U shape in cross section, surrounded
by an annular metal washer e is employed in the interior of the water
space for the purpose of preventing leakage between the rings D.
and E, such ring d and washer e being attached to the ring D by
screws, as shown.
In order to further assist in obtaining a tight joint there is placed on
cach side of the ring E between its surface and the corresponding flange
of the ring D a coil of packing g, which may be maintained in position
either by a metal band surrounding it, as shown in Figure 3, or by an
annular gland G pressed thereon by a screw i, as shown in the modifi-
cations, Figures 4 and 5. In both these modifications the packing ring
d and washere are dispensed with, and in Figure 5 the ring D is
represented as attached to the outer casing C by means of rivets a', the
water being admitted from the water space F to the water chamber A
through apertures a³.
The rings for the admission of the water and their accessories may be
further modified in various ways. For example, in Figure 6 the ring E
is arranged in contact with the outer casing C, a packing ring d and
washer e being employed in order to maintain a tight joint; a somewhat
similar arrangement of the ring E is also shewn in Figure 5, but the
coils of packing, with the gland G, are substituted for the ring d and
washer e. In the modification, Figure. 7, the stationary ring is made in
two parts, videlicet, an annular ring E of wood or other suitable material
to which the packing ring d and washere are attached, and an outer ring
E' secured to the ring E, packing 9 being interposed as shown. A
somewhat similar arrangement of the stationary ring, but differently
situate, is illustrated in Figure 8. In this case the ring D is attached to
the casing C by means of elbow pipes a, which also form the communi-
cation between the water space F and the water chamber A, and the ring

page_text: DIS FUTUROT provided with a nange bolted to it so as to overlap the
ring E'.
Figures 9 to 16 (Sheet 1) and Figures 17, 18, and 19 (Sheet 2)
illustrate another part of our Invention.
In the arrangement, Figure 9 (which is a longitudinal section of a
portion of one side of a rotary furnace), the outer casing C has attached
to it by bolts a two rings D, D, of a Z shape in cross section, which are
so placed and arranged as to leave a space between them for the insertion
of the stationary water pipe c¹, and to form a chamber F for the reception
of the water which is constantly introduced thereinto by the pipe c'
during the revolution of the furnace with the rings D, D, and is thence
discharged into the water chamber A of the furnace packing rings d, d,
and metal washers, e, e, attached by bolts f, f, are provided in order to
prevent leakage from the water space F; these rings d, d, work in contact
with the pipe c' in such a manner that the rings are constantly gripping
the pipe at one portion or other of their annular sides, the other portions
of the sides successively closing behind the pipe as they revolve.
In Figure 10, which shews a modification of the preceding arrange-
iment, a single ring D is employed, which ring is made hollow so as to
form the water space F, and is provided with an annular groove on one
side for the reception of the stationary pipe c'. This pipe is bent round
for the purpose of directing the water downwards, and is covered by a
packing ring d, which extends round the ring D, and is secured by bolts
f to the same in such a manner as to prevent leakage from the water
space F, the operation being similar to that of the rings d, d, Figure 9.
The water introduced into the space F is discharged into the water
chamber A through pipes a, which also serve to connect the ring D to
the casing C in the manner herein-before described with reference to tho
arrangement, Figure 1.
A further modification of this part of our Invention is illustrated in
Figures 11 and 12, which represent respectively a transverse section of a
furnace and a detail longitudinal section of a portion of the same drawn
to an enlarged scale. In this arrangement the ring is made in two parts,
D, D', bolted or otherwise secured together so as to leave a space at the
outer periphery for the insertion of the bent stationary water pipe c¹,
which is covered by the packing ring d, the latter being protected if
desired by a metal ring or guard e attached by bolts to the ring D.
-

page_text: In lieu of employing a chamber for the introduction of the water the
slot or space for the passage of the water pipe may be made in the outer
casing of the furnace itself, in which case the external rings D are
dispensed with.
Figures 13 and 11 are longitudinal sections, and Figures 15 and 16
respectively transverse sections of a portion of a furnace illustrating two
modes of carrying out this modification of our Invention. In the outer
casing C we form an annular slot or opening in which there is fitted
tubes or rings k, k, which are attached by angle iron 7, 7, to the casing C
in such a manner as to leave an opening between them for the insertion
of the stationary water pipe c¹, which may be either straight as shewn in
Figures 13 and 15, or bent as shown in Figures 14 and 16, packing rings
d being in both cases provided as hercin-before described.
The open slot or passage in lieu of extending unbroken round the
furnace may be intercepted, and a series of slots or openings ², c, be
provided by the division or cutting up of the continuance passage, as
shewn in transverse section, plan, and longitudinal section in Figures
17, 18, and 19, Sheet 2, respectively, the water pipe c¹ in this modification
being above the slot or passage. The packing rings d, d, of leather,
india-rubber, or other flexible material may be continuous as shown in the
Drawing, or if preferred divided so as to cover each opening c² to prevent
the escape of water.
The water pipe c' may also if desired be arranged above the furnace,
in those cases in which both the slot or passage and the packing rings
d, d, are continuous, as shewn in Figure 20, the pressure of the water
depressing the leather or other material for its admission through the
slot c³ into the chamber A. This mode of applying the pipe c¹ may be
substituted for that employed in the arrangements shewn in Figures 9
to 16 (Sheet 1).
Figure 21, Sheet 2, is a vertical section, and Figure 22 is an elevation
with the end rings in section of a rotary puddling furnace with apparatus
connected therewith illustrating a further means of admitting water to
the water chamber of the furnace. G is a flexible tube which is caused
to wind or coil around the rotary furnace C, and is connected at its end
m with the water chamber A, and which is also wound or coiled round a
drum H, and passed at its extremity n through the axis of the same.
To the end of the coil G there is fitted by means of a stuffing box o,

page_text: the water supply pipe I whence water is supplied through the coil G to
the water chamber A. The drum is suspended or supported in
bearings in brackets K, K, and is rotated simultaneously with the
rotary furnace C by means of a cord K', passing round both the drum
X, X, and the furnace. By the act of revolving the rotary furnace in
the direction of the arrow, the tube G becomes uncoiled from the drum
II, and coiled around the furnace C, but when the whole or nearly the
whole length of the tube G has been unwound from the drum H, the
motion of the rotary furnace C is reversed, whereby the tube becomes
uncoiled therefrom and coiled on to the drum II, to be again unwound
from the latter and wound on to the furnace, and so on in succession,
whereby the water is continuously supplied through the coil G to the
water chamber A of the furnace.
The drum H may be caused to move laterally by suitable well known
appliances, in order to pay out the tube G in direct line with the furnace
C, or the drum I may be of the same diameter as the furnace C, and
the lateral movement may thus be obviated.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that we are aware
that it has previously been proposed to employ a cock or bearing at the
closed or partially closed end of a double cased rotary furnace, for the
admission of water to the water chamber or space between the two
casings, and therefore to this arrangement we lay no claim, but what we
consider to be novel and original, and therefore claim as the Invention
secured to us by the herein-before in part recited Letters Patent is,―
First. The application and use to and with a double cased rotary
puddling furnace of revolving and stationary rings or tubes fitted or
placed around the external periphery of such furnace, and so constructed,
arranged, and combined, as to form an annular duct or channel for the
passage of water, substantially as and for the purposes herein-before
described and as illustrated by our drawings.
Second. Constructing in an attachment or attachments to the external
periphery of a double cased rotary puddling furnace, or in the external
casing itself of such furnace, an annular or circumferential slot or
aperture or annular or circumferential slots or apertures for the reception
or admisson of a stationary water pipe or tube or for the passage of

page_text: water, and employing in combination therewith a band or packing for
preventing undue leakage or escape of the water, the whole being fitted
and arranged and operating substantially as and for the purposes.
herein-before described and as illustrated by our Drawings.
Third. Supplying water to the water chamber of a rotary puddling
furnace by the employment of a flexible pipe or tube, communicating at
one end with such water chamber and alternately coiled around and
uncoiled from the furnace, in combination with an auxiliary revolving
drum from and around which the pipe or tube is alternately uncoiled
and coiled, such pipe or tube being fitted or attached to the drum, and
the water admitted from the water supply or source to the pipe or tube
through the centre or axis of rotation of the drum, and thence dis-
charged into the water chamber, substantially as herein-before described
and illustrated by our Drawings.
In witness whereof, we, the said Ephraim Allcock Jones and John
Allcock Jones, have to this our Specification set our hands and
scals, the Twenty-ninth day of June, One thousand eight hundred
and seventy-five.
