IMPROVEMENTS IN THE MANUFACTURE OF COACH AND CARRIAGE AXLES AND IN THE FLAPS ATTACHED THERETO
Year: 1883

page_text: LETTERS PATENT to Joseph Rigby the Elder of Walsall in the County of
Stafford Manufacturer and Isaiah Millington Morgan of the same place
Merchant for an Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
COACH AND CARRIAGE AXLES AND IN THE FLAPS ATTACHED THERETO.”
PROVISIONAL SPECIFICATION left by the said Joseph Rigby, the Elder, and
Isaiah Millington Morgan at the Office of the Commissioners of Patents on
the 2nd May 1883.
JOSEPH RIGBY the Elder of Walsall in the County of Stafford Manufacturer
and ISAIAH MILLINGTON MORGAN of the same place Merchant "IMPROVEMENTS
IN THE MANUFACTURE OF COACH AND CARRIAGE AXLES AND IN THE FLAPS ATTACHED
THERETO "
The first part of our Invention refers to cranked axles which cranks instead of
being formed from a straight bar cut and welded at the required angle are made
by taking a bar of iron which has been formed with a projection or extra thickness
of metal at the points where the cranks are to be formed we then force these
projecting or thicker portions of the bar by hydraulic or other pressure into a tool
or die of a suitable form to give the required angle to the cranks.
The second part of our invention refers to a new method of forming and attaching
the flaps or spring seatings to any description of axle requiring them and is effected
by forming a metal tool or die chanelled or sunk out to receive the axle when laid
across it and having at each side of this channel a sinking of the form required for
the flap or seating. Having laid the axle in the groove or channel a flat piece of
iron heated to welding heat is laid across it over the sinkings on each side and
being forced into these sinkings by a press or steam hammer the flaps are welded
onto the axle,

by the said Joseph Rigby, the Elder, and Isaiah Millington Morgan in the
Great Seal Patent Office on the 1st November 1883.

The first part of our Invention refers to cranked axles which cranks instead of
being formed from a straight bar cut and welded at the required angle are made by
taking a bar of iron which has been formed with a projection or extra thickness
of metal at the points where the cranks or corners are to be formed we then force
these projecting or thicker portions of the bar by hydraulic or other pressure into
a tool or die of a suitable form to give the required angle to the cranks or corners.
Referring to the drawings Figure 1 represents a portion of the bar of iron to form
the axle with the projection or extra thickness of metal at (a).
Figure 2. is the tool or die over which Figure 1 is placed the tool Figure 3 is
then brought down by hydraulic or other pressure onto the bar at (b) so as to force
the projecting portion (a) into the hollow (c) of the die Figure 2 and bend this
portion of the bar into the form of the crank or corner shewn at (e. f.) Figure 4,
the same process is gone through to form the other crank or corner at (e¹. ƒ¹)
Figure. 4. and thus the cranked axle is formed, without any fracture or disruption
of the fibre of the iron.
The second part of our invention refers to a new method of forming and attaching
the flaps or spring seatings to any description of axles requiring them and is effected
by forming a metal tool or die channelled or sunk out to receive the axle when laid
across it and having at each side of this channel a sinking of the form required for
the flap or seating, Having laid the axle in the groove or channel a flat piece of
'iron heated to welding heat is laid across it over the sinkings on each side and
being forced into these sinkings by a press or steam hammer the flaps are welded
· onto the axles.
Referring to the Drawings, Figure 5. represents the metal tool or die channelled
out or sunk at (9) to receive the axle (i) Figure 6 and having at the sides of this
channel the sinkings (hh) of the form required for the flap or seating (k) Figure 6.
which is formed out of a flat piece of iron. The axle (i) Figure 6. having been
scarfed is laid in the die Figure 5. with the plain plate across it the steam hammer
or other pressure forces the shoulders out of the axle as shewn in section at (mm)
Figure 7 the scarfing of the axle admitting of this. A rib is left in the centre of
the scarf which by the subsequent pressure is forced into the groove (n) shewn in
.section Figures 10 and 11. Figure 7a shews the (butterfly) flap Figures 6 and 7
when attached to an axle and completed. Figure 8 represents another form of tool
or die for producing a flap plain in plan. In the case of a plain axle the sinkings (0)
are omitted. Figure 9 is a plan of a plain flap.
Figures 10 and 11. are sections of the rolled bars from which the requisite lengths
are cut for the flaps Figure 10 being the section for the plain flaps and Figure 11
for the caulked ones.
We do not confine ourselves to the precise sections of iron herein illustrated.
Having thus described the nature of our said Invention and the manner in which

page_text: the same is to be carried into effect We claim The Improvements in the manufacture
of coach and carriage axles and in the flaps attached thereto as herein more fully
set forth and specified.
In witness whereof. We the said Joseph Rigby the Elder and Isaiah Millington.
6 Morgan have hereunto set our hands and seals this thirtieth day of October in
the year of our Lord One Thousand eight hundred and eighty three.
