Improvements in Machinery or Apparatus for the Manufacture of
Frame Plates 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 to be
as follows:
In the specification of former Letters Patent granted to me under date the 29th
day of October 1885, No. 13020, is described machinery or apparatus for the
manufacture of frame plates for rolling stock, such as described and claimed in the
Specification of my Patent of the same date numbered 13019, and in the Specification
of any application for Letters Patent bearing even datę herewith and numbered
15687 is described the nature of an invention constituting a further development of
the invention described in my said former Specification No. 13019.
Now my present invention has reference to machinery or apparatus suitable for the
manufacture of frame plates in accordance with the said invention described in my
other Specification of even date herewith.
For the purpose of making in one piece of metal a frame plate with flange or
flanges at one side to give the required strength and rigidity and with a fillet or
fillets at the contrary side around the openings for the axle boxes, according to my
present invention inale and female dies of special construction are employed for
producing the said flange or flanges and fillets.
For this purpose I use a wide mouthed female die or matrix the walls of which are
curved or rounded inside at the upper parts and upon which the roughly shaped plate
to be treated is placed whilst hot and which has an internal configuration corresponding
to the outline form required to be imparted to the frame plate. This female die or
matrix is fixed to the rising table or platform of a hydraulic or other press, and within
it are placed other parts that rest upon and may also be attached to the rising table,
some of these parts are constructed to receive the surfaces of thin parts of the plate
that are ultimately to be flat, others have mounted upon them other parts that project
upward to about the same extent as the wall of the main female die and are curved or

page_text: rounded at their upper parts for turning the flanges as the plate is forced into the
female die.
These last named parts, diminish in size downwards from the curved or rounded
parts and the arrangement is such as to provide free spaces between them and the
newly turned flange or flanges to admit of contraction of the plate during cooling. In
positions corresponding to the situation of those parts of the plate at which fillets are
to be formed and to be finished with square corners, spaces are provided to receive
parts of the plate that are bulged by parts of a male die to provide the requisite extra
metal at these parts for forming by one or more subsequent operations the required fillets
and with square corners. The male die which is suitably arranged for being and is fixed
to the underside of the head of the press is of a form corresponding to the general
configuration of the intended frame plate with its flange or Hanges and has parts
attached to it for forming the before mentioned bulgings which are afterwards by
suitable means released from the main part of the male die, when the female die is
withdrawn from the male die it carries with it the partially formed frame plate also
those portions of the male die used to form the bulgings and the parts used to form
the required openings (such as those for the reception of axle boxes and to give
lightness &c) in the frame plate. These said parts of dies are separately removed
previous to the removal of the plate from the female die.
In order to form the fillets and square the corners where required, the plate is
reheated, suitable modifications being made in the male and female dies, or other dies
may be used adapted for so acting upon the partially formed plate that the bulgings
become flattened, while part of the metal contained therein is caused to flow into
suitable recesses and assume the desired form.
Dated this 1st day of December 1886.

Frame Plates 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 former Letters Patent granted to me under date the 29th day
of October, 1885, No. 13020, is described machinery or apparatus for the manufacture
of frame-plates for rolling stock, such as described and claimed in the specification of
my Patent of the same date numbered 13019; and in the Specification of my application
for Letters Patent bearing even date herewith and numbered 15687, is described the
nature of an invention constituting a further development of the invention described
in my said former Specification No. 13,019.
According to such further development of the said invention I construct frame-
plates such as aforesaid in one piece of metal, not only with a flange or flanges at one
side, but also with a. fillet or fillets around the openings for the axle boxes and with
square internal corners therein, and with square corners at the ends of the frame
plates by producing bulgings or embossments at and around said parts and afterwards
by pressure forming out of the metal of such bulgings or embossments the required
fillets and square corners.
Now my present invention has reference to machinery or apparatus for performing
these operations as I will proceed to describe with reference to the annexed 5 sheets of
drawings.

Fig. 15. (Sheet 5.) is a side elevation of the mandrel M, and
Fig. 16. (Sheet 5.) is a cross-sectional elevation shewing female die J, on line 14,
of Fig. 12, also loose parts L, around the axle-box openings, and loose parts L, in
section running the whole length of the straight side of the die and around the
ends of a flanged filleted frame plate being shown between the dies I, and J.
For the purpose of making in one piece of metal a frame-plate with flange or
flanges at one side to give the required strength and rigidity and with a fillet or
fillets at the contrary side around the openings for the axle boxes, according to my
present invention, male and female dies of special construction are employed.
They are such as to make the said fillets with square internal corners, as also to
produce at the ends of the frame-plates square external corners. A, is the head of
the machine, and B, is the rising table or platform actuated by hydraulic or other
suitable mechanism.
To the head A, is fixed a compound male die C, (1, C2, which is of a form
corresponding to the general configuration of the intended frame-plate with its flange
or flanges C1, C2, being parts attached to the principal part C, for forming in
conjunction with the female die the before mentioned bulgings, which parts C1, C2,
are afterwards by suitable means released from the main part C, of the male dic.
D, is a wide mouthed female die or matrix, the walls of which are curved or rounded
inside at the upper part and upon which the roughly shaped plate to be treated is placed
whilst hot this die has an internal configuration corresponding to the outline form
required to be imparted to the frame-plate.
It will be understood therefore that the forms of the male and female dies are subject
to variation to suit the shape of frame-plate required.
The female die or matrix D, is fixed to the rising table or platform B; E, is the
floor of this female die, 6, 6, are recesses opposite the projections 5, of the male die,
by these projections and the recesses 6, the bulgings above referred to are formed upon
the frame-plate. The floor E, is securely fixed to the table B.-F, and G, are punches,
which together with the corresponding openings F 1. and G 1. in the male die, form
the flanges around the "lightening" holes in the frame-plate, H, is one of a series of
punches which in conjunction with openings H 1. in the male die effect the flanging
and bulging around the openings in the frame-plate for the axle boxes.
All these punches are placed loosely in openings in the floor E, of the female die D),
and are rounded at their tops to enable them to turn the said flanges; below their
rounded parts at and from line 7. they gradually diminish in width as they proceed
downward so as to be free within the newly forined flanging and on the recession of
the table B, from the male die, can be easily removed previously to the flanged plate
being taken out of the female die.
It will be understood that the machine comprises not only the parts shewn in Fig. 1.
but also those shewn in Fig. 2.
Figs. 5, 6, and 7, shew the part C4, which runs the whole length of the male die,
and is fitted thereto with a bevilled joint and fixed with bolts and cotters as in the case
of the parts C1, and C2, and is released at the same time and in the same manner as

page_text: those parts, namely, on the flanging operation being completed, and removal of the
above mentioned cotters, to permit of contraction of the frame-plate due to cooling.
Figs. 5, 6, and 7, also shew the flanged frame plate a, upon the male die C, and
Figs. 8, 9, and 10 shew it as it would be within the female die D, before removal
therefrom for the next operation or trimming of the edges of the flanges previous to
the formation of the required fillets or projections around the axle box openings and
square corners at the ends.
The male and female dies and mandrels used for this purpose are shown in Figs. 11
to 16 both inclusive.--I, is the male die attached to the head A, of the machine.J, is
the female die, with its component interior parts or floor K, attached to the table B, of
the machine, and loose parts L, fitted to the said floor with bevilled joints (as in the
case of the first named male die C, C1, C2) these parts L, being at the upper side of
the part K, do not require bolts and cotters, but will rest thereon.
The frame-plate, in the form in which it leaves the dies C, C1, C2, and D, is
reheated, and then is placed flange downwards in the female die J, as shewn in Fig. 11.
Mandrels M, shewn in side view in Fig. 15, are placed within the buckled parts of the
axle box openings, and mandrels N, are placed between the buckled parts at the ends
of the plate and the inner end of the female die J, to back up the metal of such parts
during the formation of the projecting fillets and square corners.
The whole are then
caused to advance against the male die I, the face view of which is shewn in Fig. 13.
0, 0, are recesses therein for forming the projecting fillets, the surfaces of these
recesses press upon the mandrels M, and cause them to descend into the axle box
recesses, pressing at the same time upon the buckled parts of the frame-plate and
causing the metal thereof to enter or flow into parts of the said recesses and to form
the required fillets with square internal corners, the plain surfaces of the male die at
the same time press against the mandrels N, which together form the end bucklings
into square cornered flanges.
The completion of this operation is illustrated in Fig. 12, the frame-plate a being
shewn still between the dies. The loose parts L, L, are arranged as shewn to allow of
contraction of the frame-plate during cooling, and as it is being forced from the female
die J, by the action of sundry small rams of the machine or by other means.
It is to be understood that I reserve to myself the right to vary the forms, proportions
dimensions and materials employed in carrying out the above invention which may be
variously modified without departure from the distinctive features thereof.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
