PROVISIONAL SPECIFICATION left by the said Thomas Beeley and
David Hanson at the Office of the Commissioners of Patents, with
their Petition, on the 11th March 1869.
We, THOMAS BEELEY, of Hyde. Junction Iron Works, in the County
of Chester, Engineer, and DAVID HANSON, of Dukinfield, in the County
of Chester, Foreman, do hereby declare the nature of the said Invention

to be as follows:-
In the first place our Invention consists in a machine, by means of
which the blows necessary for welding the seams of boilers and other
constructions are struck, instead of employing a number of labourers
for this purpose as at present. We accomplish this as follows:-The
machine consists of a number of stampers or strikers, which are arranged
side by side in a row. These stampers or strikers are so arranged that
they may be raised to a certain definite height and then be allowed to
fall by their own weight, or the force of the blow may be increased by
means of a spring. Below this row of strikers or stampers is placed the
anvil, which may be similar in shape to that now in use for this purpose,
or curved to the requisite form for welding or flanging. Various
arrangements of mechanism may be used for raising the strikers or
stampers; if plain vertical stampers are used the most convenient plan
will be to employ a shaft carrying a number of projections or cams upon
it in various positions; the revolution of the shaft causes these cams to
come into contact with corresponding projections on the stampers, and
thus raises them to the required height, when the further revolution of
the shaft withdraws the cams on the shaft from the projections on the
stampers and allows the stampers to form and strike the hot iron upon the
anvil beneath, and the cams may be so distributed round the shaft that
the stampers may be raised all at the same time or in succession.
the strikers might be arranged so as to be lifted similarly to an ordinary
tilt hammer, or directly by steam. The faces of the stampers should
he curved to suit the curve of the plate under operation, and there
should be a sufficient number of them in the machine to weld the
longest plates used in the works. Each stamper is provided with a
catch, by means of which it may be kept out of gear with the revolving
shaft, and thus be prevented from striking, as in some plates there will
probably be a portion which will not require to be welded.
Or
In the next place our Invention consists of an improved form of
furnace for heating the plates intended to be welded by the apparatus
described above. The furnace is made of sufficient length for the longest
plates used, and may be constructed of iron plates, the mouth being
narrowed along its whole length. On each side and next to the furnace
is a water chamber, which is supplied in the usual way, and next to

page_text: each of these water chambers is an air chamber, which serves to dis-
tribute the blast. The water chambers and air chambers extend the whole
length of the furnace, and a row of twyres proceed from each of the
air chambers through the water chambers into the furnace, but we
prefer to arrange these twyers so that the nozzles of one row do not
come directly opposite', but half way between those of the other row.
This furnace is not charged with fuel on the top but at the ends, the
ends being kept closed by a charge of black fuel. The advantage of
this arrangement is that it will be unnecessary to blacken that portion
of the furnace which heats the plate when feeding the furnace with
fresh fuel. This furnace is provided with dampers underneath.
In the next place our improvements consist in a novel form of furnace
for heating the ends of the cross tubes and the corresponding openings in
the flues, and the cylindrical portions of flues or boilers required to be
welded together. The furnace is made of an annular form with the
necessary twyres arranged in a radial direction around it; the twyres
passing through a water chamber, as before described.
In the next place our improvements consist in a simple apparatus
for welding the cross tubes into the flues of boilers. This consists of a
rising and falling striker, the face of which is shaped to suit the corner
formed by the junction of the flue and the cross tube. In conjunction
with this striker is an anvil similar in construction to that described in
the Specification of a Patent granted to the within-named Thomas
Beeley, bearing date the 30th day of April 1868, and N. 1421.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Beeley and David Hanson in the Great
Seal Patent Office on the 10th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
BEELEY, of Hyde Junction Iron Works, in the County of Chester,
Engineer, and DAVID HANSON, of Dukinfield, in the County of Chester
Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of March, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-

page_text: second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Beeley and David Hanson,
Her special licence that we, the said Thomas Beeley and David Hanson,
our executors, administrators, and assigns, or such others as we, the
said Thomas Beeley and David Hanson, our executors, administrators,
and 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 APPARATUS FOR WELDING
AND FLANGING PLATES AND TUBES USED IN THE MANUFACTURE OF BOILERS AND OTHER
CONSTRUCTIONS," upon the condition (amongst others) that we, the said
Thomas Beeley and David Hanson, our executors or administrators, by
an instrument in writing under our, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Thomas Beeley and David Hanson,
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:—
In the first place our Invention consists in a machine, by means of
which the blows necessary for welding the seams of boilers and other
constructions are struck, instead of employing a number of labourers
for this purpose as at present. We accomplish this as follows:-The
machine consists of a number of stampers or strikers, which are arranged
side by side in a row. These stampers or strikers are so arranged that
they may be raised to a certain definite height, and then be allowed to
fall by their own weight, or the force of the blow may be increased by
means of a spring. Below this row of strikers or stampers is placed
the anvil, which may be similar in shape to that now in use for this
purpose, or curved to the requisite form for welding or flanging.
Various arrangements of mechanism may be used for raising the strikers
or stampers. If plain vertical stampers are used the most convenient
plan will be to employ a shaft carrying a number of projections or cams

page_text: upon it in various positions. The revolution of the shaft causes these
cams to come into contact with corresponding projections on the
stampers, and thus raises them to the required height, when the further
revolution of the shaft withdraws the cams on the shaft from the pro-
jections on the stampers and allows the stampers to fall and strike the
hot iron upon the anvil beneath, and the cams may be so distributed
round the shaft that the stampers may be raised all at one time or in
succession.
A machine of this description is shewn in the accompanying Drawings
at Figs. 1, 2, 3, and 4, Fig. 1 being a side view; Fig. 2, a front view;
Fig. 3, a plan; and Fig. 4, a sectional plan taken on line a, b, in Fig. 1.
In these Figures the same letters refer to the same parts.
A, A, A, are the stampers, upon which are formed the projections
B, B, B; C is the shaft which carries a number of circular plates D, D, D,
upon which are formed the cams E, E, E. These plates are shewn in
section in Fig. 4. The stampers A, A, A, slide in suitable guides F, F,
and the force of the blow may be increased by the springs G, G. The
machine is carried by suitable side frames H, H. I is the anvil, and K
represents a plate being welded.
The above is the most convenient method with which we are ac-
quainted of putting this part of our Invention into practice, but no
doubt other methods might be adopted, for instance, the stampers might
be arranged to be lifted similarly to an ordinary tilt hammer, or directly
by steam. The shape of the face of the stampers should correspond to
the shape of the plates to be welded, being straight for flat plates and
curved for curved plates, and there should be a sufficient number of
them in the machine to weld the longest plate used in the works.
Each stamper is provided with a catch, by means of which it may be
kept out of gear with the revolving shaft, and thus be prevented from
striking, as in some plates there will probably be a portion which will
not require to be welded. The simplest form of catch for this purpose
consists of a key placed in a slet in the stamper, as shewn at I,
Fig. 1.
In the next place our Invention consists in an improved form of
furnace for heating the plates intended to be welded by the apparatus
described above. The furnace is made of sufficient length for the
longest plates used, and may be constructed of iron plates, the mouth

page_text: being narrowed along its whole length. On each side and next to the
furnace is a water chamber, which is supplied in the usual way, and
next to each of these water chambers is an air chamber, which serves
to distribute the blast. The water chambers and air chambers extend
the whole length of the furnace, and a row of tuyeres proceed from each
of the air chambers through the water chambers into the furnace, but
we prefer to arrange these tuyeres so that the nozzles of one row do
not come directly opposite, but half way between those of the other
row. Fig. 5 is a cross section and Fig. 6 is a plan of a furnace constructed
according to this part of our Invention. A is the furnace with the
narrow mouth or opening B; C, C, are the water chambers, and D, D,
the air chambers; E, E, are the tuyeres passing from the air chambers
through the water chambers to the furnace A. This furnace is not
charged with fuel on the top but at the ends, that is, at F, F, Fig. 6,
the ends being kept closed by a charge of black fuel. The advantage
of this arrangement is that it will be unnecessary to blacken that portion
of the furnace which heats the plates when feeding the furnace with
fresh fuel. This furnace is provided with dampers underneath, as shewn
at G, Fig. 5.
In the next place our improvements consist in a novel form of furnace
for heating the ends of the cross tubes and the corresponding openings
in the flues, and the cylindrical portions of flues or boilers required to
be welded together. The furnace is made of an annular form with the
necessary tuyeres arranged in a radial direction around it, the tuyeres
passing through the water chamber, as before described. Fig. 7
is a plan of this furnace. The centre A is made of fire-brick or
other suitable material; B is the annular furnace; C is the water
chamber; D is the air chamber, from which the tuyeres E, E, pass to
the furnace.

rising and falling striker, the face of which is shaped to suit the corner
formed by the junction of the flue and the cross tube. In conjunction
with this striker is an anvil similar in construction to that described in
the Specification of a Patent granted to the within-named Thomas Beeley,
bearing date the Thirtieth day of April 1868, and numbered 1421.

page_text: This arrangement is illustrated in Fig. 8. A is the rising and falling
striker, to which the necessary motion may be imparted by the revolving
shaft B. C is the anvil, of which a more detailed description will be
found in the Specification already referred to.
In witness whereof, I, the said Thomas Beeley, for and on behalf of
myself and the said David Hanson, have hereunto set my hand
and seal, this Ninth day of September, in the year of our Lord
One thousand eight hundred and sixty-nine.
