MARCAL DICITIATION.
Improved Method of and Dies for Use in Embossing or Stamping
Metallic Plates or Sheets, and Presses or Machinery for Bending
such Plates into Box-form in the Manufacture of Railway-wagon
and other Axle-boxes.
We, THE STEEL RAILWAY JOURNAL BOX COMPANY LIMITED, Pendleton, Man-
chester, and JoHN DONNELLY, Engineer of the said Company, residing at 309,
Bury New Road, Higher Broughton, Manchester, Lancashire, do hereby declare
the nature of this invention to be as follows:
This our invention has reference to an improved method, and machinery or
presses with dies for use in corrugating embossing or stamping ordinary rolled
iron or steel plates or sheets at the proper places to form spring-seats, horn-plate
grooves and dust guard grooves therein or thereon. The objects of our said
invention being to ensure that metallic plates or sheets corrugated, embossed or
stamped by such dies for axle-boxes of the same size shall be interchangeable,
of uniform thickness without impairing the fibre of such plates, without requir-
ing to be machined, at the same time retaining the hard surface skin of such
plates.
In carrying this invention into practice we use a machine or press of suitable
size similar to that described and illustrated in Specification 8656 dated 20th
May 1891, on or to the underside of the lower portion of the vertical slidable
cross-head or platen of which we cast, fasten or attach by screwed or threaded
metallic bolts, studs or the like a projection or upper portion of a metallic die of
any suitable shape, size and thickness, in the underside of which we form two
parallel suitably shaped grooves, furrows or channels of suitable length and
depth at a suitable distance apart, in each of which channels we pivottally fit
or connect the thickest side or edge of a tapering steel or like suitable metallic
tongue-piece of suitable length and width and with a rounded lower 02
free edge, which lower edges when the said upper portion of such dies is in nor-
mal position or out of action are caused by the said channels or grooves to
depend inwardly below the lower surface of such upper portion at an angle to
their point of suspension.
After a flat steel or iron plate of suitable shape, size and thickness has been
sufficiently heated it is placed upon a suitably shaped metallic mould fastened
or attached by any suitable means to the upper surface of the stationary table
of such presses, when the said cross-head or platen with the upper portion of the
die attached thereto is caused to descend by the gearing and connecting-rods of
such press, the rounded lower edge of the inwardly projecting tongue-pieces force
the heated plate against the projection on the lower fixed portion of the die so ás
to form ridges or corrugations of the required size in or on such heated plate say
for the spring-seat of such axle-boxes, such plate is then re-heated and placed
on the suitably shaped metallic mould attached to the upper surface of the table-

page_text: of a similar press so that when the platen of such press is caused to descend,
the lower rounded edge of the tongue-pieces of the upper portion of
the die will press another portion of such heated plate against the
projection of its mould SO as to form corrugations for say the horn-
plates, the plate is then removed from the machine, re-heated and placed
upon another mould in another similar press and treated in a similar manner by
a similar die or dies to form say dust-guard grooves or corrugations in such
plate, such corrugated plate is again re-heated, or if retaining sufficient heat
is placed upon a suitably shaped "former-block" formed on or attached to the
vertical slidable cross-head of a suitable press similar to that shewn at Figures 1,
2 and 3 of the drawings accompanying the printed Specification 8657 dated
20th May 1891 to which block such heated plate is clamped by any suitable
means between suitably shaped vertical slidable
swaging rollers mounted
opposite to each other at either side of such former block," so that when such
press is operated or set in motion such "former block" with the heated plate
thereon is forced upwards against an adjustable platen attached or fixed to the
press-head of such presses to form the indentation or corrugation required, at
the same time the swaging rollers' are caused to descend and bend down-
ward the sides and end or ends of such corrugated plate, or the indentation may
be first formed in such plate, and the sides and end or ends of such plate after-
wards bent downwards by such rollers by a second operation.
دو
..
It will be readily understood that by quickly passing such heated plate from
one press or machine to another after each operation it may be bent to box-
form at one heating. The meeting edges of such corrugated plate after it has
been bent into box-form may be welded together by any well known means, or
bolted together as desired after the necessary holes have been drilled or formed
through same, and afterwards fitted or finished in the usual manner.

DI MUITIVATION.
Improved Method of and Dies for Use in Embossing or Stamping
Metallic Plates or Sheets, and Presses or Machinery for Bending
such Plates into Box-form in the Manufacture of Railway-wagon
and other Axle-boxes.
We, THE STEEL RAILWAY JOURNAL BOX COMPANY LIMITED, Pendleton, Man-
chester, in the County of Lancashire, and JoHN DONNELLY, Engineer of the said
Company, 309, Bury New Road, Higher Broughton, Manchester, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement
This our invention has reference to an improved method of and mechinery or
presses with dies for use in corrugating, embossing or stamping rolled iron or
steel plates or sheets at the proper places to form spring-seats, horn-plate grooves
and dust guard grooves therein or thereon. The object of such invention being
to ensure that metallic plates or sheets corrugated, embossed or stamped by such
dies for such axle-boxes of the same size shall be interchangeable without re-
quiring to be machined, of uniform thickness without impairing the fibre of
such plates at the same time retaining the hard surface skin of such plates.

page_text: in detail we have hereunto annexed two sheets of drawings on which letters of
reference are marked.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side clevation, and Figure 2 a front elevation partly in section
of a press or machine having two tapering metallic tongue-plates or toggles
pivottally connected at their thickest side to the underside of the slidable cross-
head of such machine, and a mould formed or cast on the upper surface of the
table of such press.
Figure 3 is a plan view of a blank steel or wrought-iron plate cut by any suit-
able means or punched or stamped to the shape shewn before being embossed
or corrugated by means of a similar die to that shewn attached to the machine
or press illustrated at Figures 1 and 2.
Figures 4 and 5 are a plan and edge view respectively of the metallic plate
shewn at Figure 3 after being embossed or corrugated by the die attached to
such machine.
Figures 6, 7 and 8 are a front elevation, a side elevation partly in section
and a sectional plan view respectively of a machine or press with suitable metal-
lic rollers for bending the metallic plate after being corrugated or embossed in
suitable positions into box-form.
Figure 9 is a plan view of the shell of the box after being bent; but before
being welded.
Figures 10, 11 and 12 are a side elevation, a back end elevation and a plan
view respectively of the shell of such box after being welded.
On referring to the drawings hereto annexed we take a steel or wrought-iron
plate of suitable size and thickness cut out or stamped to the shape shewn at
Figure 3 which we heat, or make to a red-heat and place by tongs or other suit-
able means upon a suitably shaped steel or other suitable metallic block b cast
or formed on or bolted to the upper surface of the stationary table c of the
press shewn at Figures 1 and 2.
When such machine is set in motion the cross-head d will be caused to des-
cend having a steel or like suitable metallic block e formed on or bolted to its
underside with a depending steel or like suitable metallic projection f of suit-
able shape and size formed thereon so as to depress the central portion of such
heated plate at g to form a spring seat, the tongue-pieces or toggles h pivot-
ted at their upper or thickest edge within grooves formed in the said upper
portion e of such die at the same time pressing or forcing the side portions of
such heated plate against the lower portion b of such die, such embossed or cor-
rugated plate is then removed from such die by any suitable means to another
or similar press having the upper portion of a metallic die with similar pivotted
metallic tongue-plates or toggles so as to form ribs i of suitable shape and size

page_text: thereon in proper position with grooves between for the horn-plates, and an
internal groove k for the dust-guard of such axle-boxes.
Such corrugated or embossed metallic plate while in a heated state is then
placed by any suitable means upon the upper end of a steel or like suitable
metallic former-block corresponding in shape and size to the form to which
such plate is to be bent, formed on or attached to the upper surface of a vertical
slidable metallic cross-head m of the machine illustrated at Figures 6, 7 and 8
similar to that described and illustrated in the printed Specification 8657 dated
20th May 1891, the metallic swaging rollers n being above the adjustable
metallic head or platen o or at their highest lift or point, the form or former-
block at its lowest point to enable the heated metallic plate a to be placed
upon such former-block, then when such machine is set in motion the cam p
by means of the roller and its connecting rods r forces up the cross-head m
and its former-block with the plate a thereon up between the guides s of
the machine so as to press or grip such corrugated plate a against the underside
of the adjustable head or platen o whilst at the same time the swaging rollers n
are drawn or forced down by the excentrics t and their rods u so as to bend such
plate against the former-block 7, when the swaging rollers n have been forced
into the position shewn by dotted lines at Figure 6, the partially formed metal-
lic axle-box is removed by any suitable means from such former-block and
placed over or upon another cast-steel or like suitable form or former-block
having vertical ribs or projections of suitable shape and height on same, and
metallic rollers circumferentially grooved as shewn at Figure 8 to correspond
to the configuration of the horn plate grooves j, ribs i and groovek in the shell.
After the plate has been bent along the longitudinal parallel lines 2-2, 3-3
by a machine such as described having plain parallel metallic rollers fitted
thereto at a distance apart corresponding to the greatest width of the box to be.
formed, and the portions 4-4, 5-5 and 6 of the plate beyond these lines bent
at right angles to the plane of the plate, such plate is then bent by the above
machine on the transverse parallel lines 7-7, 8-8 to a box like form, the por-
tions 4-4, 5-5, and 6 lapping at the front end and back end of the former-
block used so that their edges meet and are subsequently welded together.
After a suitably shaped cast-iron or cast-steel distance block has been inserted
and fixed in position within such shell or box to form a seat for the journal-brass
or bearing and to act as a seat for the carrying spring and transmit all pressure
or crushing strains upon such spring through such sheet metal to such journal
bearing so that the embossed or corrugated metallic shell by which the said spring
is supported will be strengthened internally to avoid bending strains on such
axle-box shell, the sides of such cast-iron or cast steel liner which fits tightly
within the upper portion of such shell may be left flat, or be ribbed to correspond
in shape to the internal configuration of such shell where the horn-plate grooves
are formed to support those embossed portions, the bottom steel or other metallic
portion of such boxes being afterwards welded in proper position to the sides
and ends of such shell or rivetted thereto. By quickly passing the said heated
metallic sheet or plate from one machine or press to the other machine or press
such plate may be bent entirely to a shell or box-form at one heating, thus
obviating frequent heating of such plate.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
:
The application to the upper surface of the stationary table of any suitable
press or machine of a metallic form block b, and to the underside of the slidable
cross-head of such machine of a metallic block e having a depending portion f
and two tapering metallic tongue-pieces or toggles pivotted at their upper or
thickest side or edge within suitably shaped grooves formed in such block so

page_text: that such toggles are caused by one side of their respective grooves to incline
or project inwardly beneath such upper block e at an angle to their pivot or
point of suspension for use in corrugating, embossing or stamping metallic plates
at the proper places to form spring seats, horn-plate grooves and dust-guard
grooves in such metallic plates for railway-wagon and other axle-boxes, arranged
as shewn on the drawings hereto annexed and herein substantially described.
