Improvements in Machinery or Apparatus for the Manufacture of
Frame-plates and Analogous Articles for Rolling Stock.
I, SAMSON Fox, of the Leeds Forge, New Wortley, Leeds, in the County of York,
Engineer and Ironmaster, 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 :—
In the Specification of Letters Patent No. 13020, dated 20th October 1885,
granted to me for "Improved machinery or apparatus for the manufacture of frame
or horn plates for rolling stock," are described male and female dies by means of
which and suitable pressing machinery such frame or 'horn plates are produced, and
in the Specification of Letters Patent No. 15688, Dated Decr. 1. 1886, also granted
to me, are described certain improvements in the construction of the male and
female dies for the production of frame plates such as above referred to.
By means of the male and female dies as above described and illustrated, only one
size of frame-plate can be made, this I find is very inconvenient in practice as well
as expensive, and as various forms and dimensions of frame-plates are required to be
made, and in order that they should be made as cheaply as possible my present inven-
tion has reference to further improvements in the construction of male and female
dies which I build up in such sectional parts and in such manner. as to admit of such
variations as will meet the changes in form and dimensions of frame-plates and other
analogous articles that may be required to be produced.
Such improved construction of dies I will now proceed to describe with reference
to the annexed two sheets of drawings in which similar letters and numerals represent
like parts in all the Figures.
Fig. 1. Sheet 1. shews in plan to the line 1. 1. one half of a pair of my improved
dies, D, being the female die the walls of which can be enlarged or diminished at
pleasure, the parts D 1, of which are in horizontal section at the line 2, of Fig. 4.
The male die C, which comprises the parts C1, C2, C3, C4, C5, and C 6, is in horizontal
section at the line 3, of Figs. 3, 4, and 5. The parts C1, C2, and C3, of the male
die, and D 1 of the female die in which the axle guard portions of a frame-plate are
formed, 1 construct in suchwise that they can he enlarged or diminished as may be
desired, parts C 1, of the male die and the parts D 1, of the female die being adjustable to
suit circumstances, C2, is one of a number of parts which I provide of various thicknesses
for interposition between the parts C 1, and C 1. when required to extend them. The
parts D 1, D 1. of the female die being adjustable to the positions of the corresponding
parts C 1, C1, of the male die.
The distance between one axle guard and another I also make adjustable by parts
such as C4, of the male die, these may be varied in their respective lengths so as to
suit any required centres of axle-guards, corresponding portions of the walls of the
female die being similarly adjustable.
Fig. 2, sheet 2, is a plan of the contrary portions of the male and female dies
corresponding with those shewn in Fig. 1. these although shewn in separate Figures
are continuous, their point of junction being at the lines 1, 1, of Figs. 1 and 2,
respectively.
Fig. 3, is an elevation of the parts C 3, and 4, taken at the line 4, Figs. 1, and 2,
part of which forms the longitudinal junction of those parts, (the parts C1, and (2 and
one half of the parts C 4 being removed,) the end parts C5. and the female die D, being
in vertical section on the said line 4.
Fig. 4, Sheet 2, is an elevation of that part of the male die C, from the line 1, 1,
on the left of the Figure to the right hand end thereof, and also a sectional elevation

page_text: Fig. 5, Sheet 1, is a sectional elevation of the dies at the line 6 Fig. 1.
Fig. 6, Sheet 2, is a vertical section on the line 7. of Fig. 2, (6, are separate or
loose parts fitted by means of a bevilled joint E, around the lower outside edge of
the male die C, and correspond to the parts C4, referred to in my former specification
No. 15688, Decr. 1. 1886, and held to the upper parts of the male die by the
bolts 8, and cotters 9. When the process of pressing a frame plate into form has
proceeded so far that the plate is held between the top of the female die and the face
of the male die, the cotters 9, may be removed in order that upon the said forming
being completed the parts C1, to C5, of the male die may at once be withdrawn,
leaving the parts (6, upon the newly formed plate to allow for shrinkage during
cooling, as fully described in my former Specification No. 15688, above referred to.
Parts C7, Figs. 1. 2 and 4, in the female die D, are also to allow of shrinkage between
one axle-guard and another during cooling,-, is the frame-plate within the dies after
having been formed.
It will be understood that in the formation of analogous articles hereinabove
referred to, I use male and female dies of similar construction to those above.
described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The improved construction of male and female dies for use in the manufacture of
frame plates and of other analogous articles for rolling stock, the construction being
such as to admit of being varied in size, thus rendering such dies of more universal
application than dies as heretofore constructed, substantially as described and shewn
in the annexed drawings.
Dated this 11th day of December 1889.
