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 to
be as follows:―
In my specification N° 13019 bearing even date herewith is described a new or
improved manufacture of frame or horn plates for locomotives and other rolling
stock according to which a frame or horn plate of the desired form with flange or
flanges to give it the required strength and rigidity is made of a single plate of
metal by pressing or stamping, and my present invention has reference to machinery
or apparatus for the manufacture of such frame or horn plates. For this purpose
I use a femalé die or matrix having an internal configuration corresponding to the
external form required to be imparted to the frame plate, and in conjunction with
this female die or matrix I use a male die of corresponding external form but
smaller to such an extent that when the male die is within the female die or
matrix there remains or remain between them a space or spaces of a width
corresponding to the thickness of plate to be operated upon, such space extending
entirely around the male die when the frame or horn plate is to be made with
a single flange extending entirely around it. By hydraulic or other power one or
both of the dies is or are operated so that a plate pressed between them has its
edges turned up or flanged and passes through the female die on to blocks or
supports able to move freely in all directions parallel with the face of the flanged
plate to which end the blocks or plates are arranged to rest upon anti-friction balls.
Above the flanged plate other blocks are placed and these are by the male die or
head of the press caused to bear against the flanged plate so that it is held or
gripped between the blocks situate above and below it in such manner as to admit
of the cooling and contraction but to prevent warping or buckling to which end
anti-friction balls are introduced between the upper blocks or pressers and the
male die or head of the press.

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 my application for Letters Patent N° 18019, dated
October 29th 1885, is described a new, or improved manufacture of frame or horn-
plates for locomotives and other rolling stock, according to which a frame or
horn-plate of the desired form with flange or flanges to give it the required strength
and rigidity, is made of a single plate of metal by pressing or stamping, and my
present invention has reference to machinery or apparatus for the manufacture of
such frame or horn-plates. For this purpose I use a female die or matrix having
an internal configuration corresponding to the external form required to be
imparted to the frame plate, and in conjunction with this female die or matrix
I use a male die corresponding in external form but smaller to such an extent that
when the male die is within the female die or matrix there remains or remain
between them a space or spaces of a width corresponding to the thickness of plate
to be operated upon, such space extending entirely around the male die when the
frame or horn-plate is to be made with a single flange extending entirely around it.
By hydraulic or other power one or both of the dies is or are operated so that
a plate pressed between them has its edges turned up or flanged and passes through
the forming part of the female die on to blocks or supports able to move freely in
all directions parallel with the face of the flanged plate, to which end the blocks
or plates are arranged to rest upon anti-friction balls, or the blocks may be in pairs
or sets one above the other with anti-friction balls between them.
When the plate has been passed through the forming portion of the female die,
the male die is caused to retire, and other blocks or plates (similar to those on
which the flanged plate now rests) are placed upon the flanged plate, and the male
die or head of the press is brought to bear upon the blocks or plates, and those in
immediate contact with the plate under treatment press upon it so that it is
held or gripped between the blocks situate above and below it in such manner as to
admit of contraction due to cooling and to prevent warping or buckling, antifriction
balls are introduced between each pair or set of the upper blocks or pressers.
The edge or edges of the flange or flanges are next machined or otherwise trimmed
to the desired form,
In the annexed drawings, Fig. 1, represents a face view of the male die a,
Fig. 2, is a sectional elevation shewing the male and female dies a, and b,-gripping
or holding apparatus and an interposed frame or hornplate c, and Fig. 3, is a plan
of Fig. 2, without the male die a. d, d¹, are holding or gripping plates, the lower
of which rest upon the bed or table of the press, and g, g, are anti-friction balls
between them, the plates d¹, receive the plate c. on its being pressed through the
forming portion of the female die b, by the male die a. which is attached to a part

page_text: of the press and is afterwards either caused to retire from contact with the plate
under treatment, or the female die b, together with the plate c. may be caused to
descend to such an extent as to permit holding or gripping plates f. fl. with anti-
friction balls g 1. between them, to be placed upon the now flanged plate c. The
male die a, is next caused to bear upon the gripping plates f, f1. so that the flanged
plate is slightly squeezed between the series of holding or gripping plates d 1. and f
in such manner as to admit of contraction of the plate due to cooling, the rolling
motion of the anti-friction balls g, g 1. between the plates d d 1, and f, fl,
permitting such contraction while preventing warping or buckling thereof.
As is evident, the forms, proportions, and dimensions of the dies will depend
upon the precise form of frame or horn-plate to be produced.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
1. For the manufacture or formation of flanged frame or horn plates for rolling
stock by pressure machinery or apparatus substantially such as described with
reference to the drawings.
2. In the manufacture of frame or horn-plates, the use of holding or gripping
blocks or plates with anti-friction balls between them substantially as described for
the purpose specified.
Dated this 22nd day of July 1886.
