An Improvement or Improvements in the Manufacture of the Shoes
of the Springs of Railway Carriages, Trucks, and Wagons.
We JABEZ LONES and CHARLES VERNON and EDWARD HOLDEN and RALPH BENNETT
trading as Lones Vernon and Holden of Sandwell Iron Works Smethwick in the
County of Stafford Manufacturers do hereby declare the nature of this Invention to be
as follows:-
Shoes for the springs of railway carriages trucks and wagons cousist each of a
horizontal base plate having at about its middle side ears of nearly a semi-circular
figure and situated at right angles to the base plate the said side ears are considerably
thinner in substance than the base plate. Between the side ears of the shoe the end
of the spring is confined. The said shoes are ordinarily made by forging from a bar
of wrought iron or steel the longitudinal marginal parts of which are thinner in
substance than the middle part. From the thick middle part of the bar the base plate
is made and from the thinner marginal parts of the bar the side ears are made. In
bending at right angles the parts of the bar to form the side ears a rounded meeting
edge is formed between the side car and the base plate and in order to give a square
or angular figure to the said rounded meeting edge a filling piece is welded to it so as
to strengthen the said meeting edge.
The object of our invention is to facilitate the manufacture of the said shoes
by the production of an angular or square edge at the meeting of the side ear
with the base plate without the necessity for the welding of an additional filling piece
at the part referred to.
This we effect by manufacturing the said shoes from rolled bar iron or steel
made in the manner and having the sectional figure hereinafter described.
According to our invention we roll a bar of iron or steel flat on one face, and of
different thicknesses on the other face the middle part of the bar being considerably
thicker than the longitudinal marginal portions of the bar. Where the thin side
marginal parts meet the thicker middle portion of the har longitudinal ribs are formed
the summits of the said ribs having by preference a rounded figure the said ribs
standing a short distance above the level of the thick middle of the bar thereby giving
to the middle part of the bar a shallow trough shaped figure in cross section the longi-
tudinal ribs forming the sides of the trough. We roll the ribbed or trough shaped bar
having thin side parts from the bloom or billet by a series of by. preference three
rollings the rolls having the required figures to produce the said bar.
In making shoes from the said bar it is divided transversely into pieces of the
required length. The thin side parts of the cut off length having been shaped they are
bent towards the flat face of the said length and at right angles thereto to form the
said ears of the shoe. When the ears are thus bent the metal of the ribs is so disposed
that an angular or square meeting edge of the ears with the base plate of the shoe
is formed without the treatment subsequently required when iron or steel bars of the
ordinary sectional figure are used.

An Improvement or Improvements in the Manufacture of the Shoes
of the Springs of Railway Carriages, Trucks, and Wagons.
We JABEZ LONES and CHARLES VERNON and EDWARD HOLDEN and RALPH BENNETT,
trading as Lones, Vernon and Holden, of Sandwell Iron Works, Smethwick, in the
County of Stafford, Manufacturers, do hereby declare the nature of our invention and
the manner in which the same is to be performed, to be particularly described and
ascertained in and by the following statement:
Shoes for the springs of railway carriages trucks and wagons consist each of a
horizontal base plate having at about its middle, side ears of nearly a semi-circular
figure and situated at right angles to the base plate; the said side ears are considerably
thinner in substance than the base plate.
Between the side oars of the shoe the end of the spring is confined. The said shoes
are ordinarily made by forging from a bar of wrought iron or steel the longitudinal
marginal parts of which are thinner in substance than, the middle part. From the
thick middle part of the bar the base plate is made and from the thinner marginal
parts of the bar the side ears are made. In bending at right angles the parts of the
bar to form the side cars a rounded meeting edge is formed between the side ear and
the base plate; and in order to give a square or angular figure to the, said
rounded meeting edge a filling piece is welded to it so as to strengthen the said
meeting edge.
The object of our invention is to facilitate the manufacture of the said shoes
by the production of an angular or square edge at the meeting of the side
car with the base plate without the necessity for, the welding of an additional filling
piece at the part referred to.
This we effect by manufacturing the said shoes from rolled bar iron or steel made in
the manner and having the sectional figure hereinafter described.
According to our invention we roll a bar of iron or steel flat on one face and, of
different thicknesses on the other face, the middle. part of the bar being considerably
thicker than the longitudinal marginal portions of the bar. Where the, thin sido
marginal parts meet the thicker middle portion of the bar, longitudinal ribs, are,
formed, the summits of the said ribs, having by reference a rounded figure, the said
ribs standing a short distance above the level of the thick middle of the bar thereby,
giving to the middle part of the bar a shallow trough shaped figure in cross section, the
longitudinal ribs forming the sides of the trough. We roll the, ribbed or trough.
shaped bar having thin side parts, from the bloom or billet by a series of, by preference,
three rollings, the rolls having the required figures to produce the said bar.
In making shoes from the said bar it is divided transversely into pieces of the
required length. The thin side parts of the cut off length having been shaped they
are bent towards the flat face of the said length and at right angles. thereto to form
the side ears of the shoe. When.,the ears are thus, bent the metal of the ribs is so.
disposed that an angular or square meeting edge of the ears with the base plate of the
shoo is formed without the treatment subsequently required when iron or steel, bars,
of the ordinary sectional figure are used.
Figure 1 of the accompanying drawing represents in cross section and plan the
rolled bar of iron or steel which we use in the manufacture according to our, invention:
of the shoes for the springs of railway carriages, trucks, and, wagons. It will be seen
by referring to the sectional view of the said bar that it is flat on one face and of
different thicknesses on the other face, the middle part a being considerably thicker
than the longitudinal marginal portions b, bof the bar. At the junction of the two
thicknesses of metal a and b, b on one face of the bar are longitudinal ribs c, c having
preferably rounded summits as represented. These longitudinal ribs c, c stand a short
distance above the level of the thicker middle portion a of the bar, and form between
them a shallow trough at the middle of the bar. The bar Figure 1 is rolled from the
bloom or billet by a series of rollings three rollings being generally sufficient, the

page_text: rolls having the required forms to produce the said bar. The construction of the rolls
and the process of rolling do not differ essentially from rolls and the process of rolling
ordinarily employed in the production of bars of other sectional figures. The shoes
are made from a long rolled bar of the kind represented in Figure 1 in the following
manner. We divide the bar transversely into pieces each piece having a length
sufficient to form a shoe.
We heat the cut off lengths of the bar Figure 1 and by means of a pair of clipping
or cutting out tools we cut from the heated cut off length a blank of the kind
represented in plan in Figure 2, that is, the thin side parts b, b of the cut off length
are rounded as shown at 6, 63 leaving the thicker projecting parts a², a3 at the middle
of the blank to form the ends of the base plate of the shoe. The parts at 63, 6² from
which the side ears of the shoe are made may have any desired shape, given to them.
By the ordinary forging operation the side parts b², 62 of the fashioned blank
Figure 2 are bent downwards or towards the flat face of the blank as indicated by
the arrows so as to bring the ribs c, c on the outside of the shoe.
The said side parts, are bent at right angles to the middle part of the blank
and form the side cars of the shoe as represented in plan in Figure 3; side elevation
in Figure 4 and end elevation in Figure 5, where the side ears of the shoe are
marked, and the base plate is marked a. On the bending of the side ears 63, 62
the metal of the ribs c, c at the junction of the thicker part or base plate a with the
thinner ear pieces 63, 62 is so disposed that an angular or square meeting edge of the
ear pieces 6, with the base plate a of the shoe is formed as represented at d, d
Figures 4 and 5 instead of the ordinary rounded meeting edge and the filling pieces
ordinarily welded to the said rounded edges are dispensed with and the manufacture
of the shoes consequently facilitated.
The shoe is finished in the ordinary way.
Having now particularly described and ascertained the nature of our invention
and the manner in which the same is to be performed we declare that we claim as our
invention of "An improvement or improvements in the manufacturo of the shoes of
the springs of railway carriages trucks and wagons":
Manufacturing the said shoes from cut off pieces or lengths of a rolled bar of iron
or steel of the kind herein before described and illustrated in Figure 1 of the accom-
panying Drawing, the said bar being flat on one face and of different thicknesses on
the other face, the middle part of the bar from which the base plate of the shoe is
made being considerably thicker than the longitudinal marginal parts from which the
side ears of the shoe are made the middle thick part of the bar joining the thinner
side parts by longitudinal ribs for the purpose and substantially as described and
illustrated.
