PROVISIONAL SPECIFICATION.
Improvements in 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. 13019, is described the manufacture of frame-plates
for locomotives and other rolling stock, each made of the desired form with flange or
flanges to give it the required strength or rigidity, of a single plate of metal by
pressing or stamping.
Now my present invention has reference to a further development of the said
former invention according to which I produce not only a flange or flanges at one
side of the plate, but likewise a fillet or fillets, (or projection or projections) where
required (as for example around the openings for the axle boxes) at the other side of
the plate as I will proceed to describe.
A plate of metal such as mild steel, as referred to in my former Specification,
having been cut roughly to approximately the required form of the intended finished
frame-plate, is heated to a suitable temperature and pressed or stamped to nearly the
required shape with flange or flanges on one side. Those parts at which it is intended
to form fillets are bulged outward at the reverse side of the plate to that at which the
flange or flanges is or are formed.
This having been done, the plate is again heated, once or oftener as required and
whilst hot is subjected to a further pressing or stamping operation or operations
whereby the bulged parts above referred to are mainly flattened so as to coincide with
the plain surface of the main body of the plate, but part of the metal of each bulged

page_text: part is caused to flow into a recess or recesses in a suitable die whereby there is
imparted to it the form of a fillet or fillets so as to provide for such projecting parts
being trued up after they become worn by the friction of the axle-box flanges thereon,
or by lateral play or oscillation of the rolling stock, without encroaching on the
thickness of the body part of the frame plate.
For producing frame plates according to this invention, any suitable apparatus may
be employed, preferring such as is described in the Specification of my other
application for Letters Patent bearing even date herewith and numbered 15688.
The fillets and the edge or edges of the flange or flanges produced as described, are
subsequently trimmed.

Improvements in 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, 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. 13019, is described the manufacture of frame plates
for locomotives and other rolling stock, each made of the desired formn with flange or
flanges to give it the required strength or rigidity, of a single plate of metal by
pressing or stamping.
Now my present invention has reference to a further development of the said
former invention, according to which I produce not only a flange or flanges at one
side of the plate, but likewise a fillet or fillets (or projection or projections) where
required, (as for example around the openings for the axle boxes,) at the other side of
the plate as I will proceed to describe."
A plate of metal such as mild steel as referred to in my former Specification,
having been cut roughly to form somewhat larger than the intended finished frame
plate, and having been otherwise suitably prepared, for example, as represented in
Fig. 1, of the accompanying drawings, is heated to a suitable temperature (say
900 degrees Fahrenheit or thereabout) or say to a bright-bright red heat, and pressed
or stamped to nearly the required shape as represented in Figs. 2, and 3, with flange
or flanges on one side. Those parts at which it is intended to form fillets or square
corners, are bulged or embossed outward at the reverse side of the plate to that at
which the flange or flanges is or are formed, as shewn at a, Fig. 3.
This having been done, the plate is again heated, once or oftener as required, and
whilst hot is subjected to a further pressing or stamping operation or operations
whereby the bulged or embossed parts a, by being pressed or caused to flow into a
recess or recesses in a suitable die, has imparted to it the form of a fillet or fillets
such as shewn at c, Fig. 4, and in Fig. 6. in section taken at 1, 1, Figure 4, to a
larger scale, and at the same time is made to form square corners at d, and e, Fig. 4,
and Fig. 5. (large section in line 2, 2, Fig. 2.) and Fig. 6.-The said fillets or
projections c, allow of being trued up after they become worn by the friction of the
axle-box flanges or by lateral play or oscillation of the rolling stock, without
encroaching on the material of the main body or part of the frame-plate.
The fillets and the edge or edges of the flange or flanges after being produced as
described are trimmed.
For producing frame plates according to this invention, any suitable apparatus may
be employed, preferring such as is described and illustrated in the Specification of my
other application for Letters Patent of even date herewith and numbered 15688.

page_text: It is to be understood that I reserve to myself the right to vary the forms, pro-
portions, dimensions, and other details to suit the requirements of various applications
of my invention above set forth.
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
1. The method or process of manufacturing frame plates for rolling stock, with
flanges and with square corners, and fillets or projections, which consists in cutting a
suitable plate to approximately the form but somewhat larger than the required
frameplate, heating same, producing by pressure the required Hange or flanges at one
side, and bulgings or embossments at the contrary side, reheating the plate and by
pressure forming out of the metal of said bulgings or embossments the desired square
corners and fillets or projections substantially in the manner hereinabove described.
2. As a new article of manufacture, a frame plate for rolling stock with flange or
flanges at one side, and square corners, fillets or projections at the reverse side,
produced by cutting a suitable plate to approximately the form but somewhat larger
than the required frame-plate, heating the same, producing by pressure the required
flange or flanges at one side, and bulgings or embossments at the contrary side,
re-heating the plate and by pressure forming out of the metal of said bulgings or
embossments the desired square corners and fillets or projections substantially in the
manner hereinabove described.
Dated this 26th day of August 1887.
