PROVISIONAL SPECIFICATION.
An Improved Power-operated Press for Stamping or Embossing
Sheet Metal in the Manufacture of Axle Boxes and other
articles.
We, THE PATENT STAMPED STEEL RAILWAY AXLE BOX COMPANY
LIMITED, of Leadenhall Buildings, in the City of London, and JOHN DONNELLY,
of 45 Brockley Road Brockley in the County of Surrey, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improved power-operated press particularly designed
for stamping or embossing sheet steel in the manufacture of axle boxes by the
process described in the Specification of former Letters Patent dated November 15th
1889, No. 18303; but applicable also for stamping and embossing metal in making
other articles.
In the operation for which this improved press is principally designed, the
plate of steel cut to shape is pressed between successive pairs of dies for the purpose
of forming the spring seat and of corrugating the plate at the proper places to
form the horn plate and dust guard grooves.
The improved press comprises a fixed table supporting the lower die or dies, and
a sliding cross-head or platen, to the under side of which the corresponding upper
die or dies would be attached, this cross-head or platen being fitted to work in
vertical guides and receiving reciprocating motion by connecting rods taking hold
of gudgeons at the ends of the cross-head or platen, and of crank pins on the ends
of a shaft mounted in the frame below the stationary table, the connecting rods being
outside the uprights of the frame.
The crank shaft is driven by a train of spur gear from a first motion shaft driven
by a belt, a friction clutch being interposed between the belt pulley and the first
motion shaft.

COMPLETE SPECIFICATION.
An Improved Power-operated Press for Stamping or Embossing
Sheet Metal in the Manufacture of Axle Boxes and other
articles.
We, THE PATENT STAMPED STEEL RAILWAY AXLE Box COMPANY
LIMITED, of Leadenhall Buildings, in the City of London, and JOHN DONNELLY,
of 45, Brockley Road, Brockley, in the County of Surrey, Engineer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to an improved power-operated press, particularly designed
for stamping or embossing sheet steel (in the manufacture of axle-boxes by the
process described in the Specification of former Letters Patent dated November 15th
1889, No. 18303) but applicable also for stamping and embossing metal in making
other articles.

page_text: In the operation for which this improved press is principally designed, the plate
of steel cut to shape is pressed between successive pairs of dies for the purpose of
forming the spring seat and of corrugating the plate at the proper places to form
the horn plate and dust guard grooves.
The improved press is illustrated in the accompanying drawings, forming part
of this Specification, and will be described with reference thereto.
Figure 1 is a half-sectional front elevation and Figure 2 a side elevation, of the
machine.
Figure 3 is a horizontal section, on line 1-1 Figure 1, and Figure 4 a horizontal
section, on line 2-2.
The same letters of reference denote like parts in all the figures.
A is the base plate, B the side standards, C the top stretcher, and D a table
fixed on the side standards B. E is a vertically-sliding cross-head or platen fitted
to work in vertical guides in the side-standards B and receiving reciprocating
motion by connecting rods F, F, taking hold of gudgeons e at the ends of the
cross-head or platen E, and of eccentric or crank pins y on the ends of a shaft G
mounted in the frame below the stationary table D, the connecting rods F being
outside the standards B which are slotted at the upper part to give passage to the
gudgeons e. The crank shaft G is driven by a central train of spur gear H, I, J, K,
(indicated by pitch lines in Figure 2) from a first motion shaft L driven by a belt,
a friction clutch M being interposed between the belt pulley and the first motion
shaft to enable the machine to be readily started and stopped between each pressing
operation. The lower die or dies would be bolted upon the table D and the corre-
sponding upper die or dies would be bolted to the under face of the sliding cross-
head or platen E.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
The herein-described power-operated press consisting essentially in the combina-
tion, with a stationary table, of a vertically-sliding crosshead or platen above said
table connected by end gudgeons and connecting rods outside the framing, with
eccentric or crank pins on a shaft below the said table, driven by a central train of
spur gear, substantially as specified.
