I JOHN WILLIAM HENRY JAMES of No. 9, Victoria Chambers, Westminster in the
County of Middlesex, Civil Engineer do hereby declare the nature of this invention to
be as follows:-
The object which I have had in view in perfecting my present improvements has
been to provide from each sheet or blank of steel iron or other metal employed a
complete transverse sleeper with one or both chairs formed of the same metal and
this without apertures or cuttings in the metal. Such transverse sleepers and chairs
are light in weight, have sufficient elasticity when a rolling load is passing and by
reason of the new form and being without cuttings in the body of the metal are very
durable.
In carrying my invention into practice I form the blank into an inverted trough
with a raised ridge along the top and I at the same time raise portions of the raised
ridge with closed double ends so that they form chairs, or the above operations may
be perforined consecutively. By preference I stiffen these closed double ended sleepers
by raising portions of the metal at their backs or ends.
The machinery or apparatus which 1 employ consists in the combination of a die
and matrix for shaping the sleeper with a die or dies and jaws for forming one or
more chairs with the sleeper. The sleeper die and the chair dies are caused to rise
and fall together by means of connecting rods and cranks or equivalent mechanism.
The matrix remains stationary. The chair forming jaws aro pivotted to the base of
the machinery or apparatus and receive to and fro motion by toggles or equivalent
devices so as to squeeze the metal to form chairs around the chair dies whilst such
dies are between the said jaws.

I JOHN WILLIAM HENRY JAMES of No. 9 Victoria Chambers Westminster in the
County of Middlesex, Civil Engineer 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:-

with chair produced under my invention for carrying double headed rails.
body of sleeper, b raised arch shaped ridge, e jaws raised in part above the ridge in
the form of a buttress, the remaining portion marked d being depressed to the level
of the main body of the sleeper. In some cases the rail bed portion d may be depressed
below the level of the main body of the sleeper.

Figs. 5 and 6 are elevations part being in section of modifications of sleepers for a
double headed and flanged rails respectively in which the upper portions of the
chair jaws c are not raised above the top of the arched ridge b.

page_text: Fig. 7 is a transverse section, and fig. 8 a longitudinal section of apparatus for
forming transverse sleepers and chairs under my invention. 1 bed plate and frame.
2 die for shaping the sleeper, 3 dies for shaping the chairs. These dies are coupled
to the connecting rods 4 and are free to rise and fall within guides 5 in the frame 1.
6 crank shaft for giving motion to the connecting rods and dies. 7 driving pulley.
8 matrix formed with the bed plate 1. 9 jaws for operating in combination with the
dies 3 to form the chairs; the said jaws are pivotted to the bed plate at 10 through
links 11 and are operated by toggle arms 12. 13 metal to be shaped into a sleeper
chair. The parts are actuated by any suitable motor.
In figs. 7 and 8 the metal 13 is in position to be shaped. Fig. 9 is a cross section,
and fig. 10 an elevation of the bed plate showing the metal acted on and formed into
a sleeper chair.
Fig. 11 is a transverse section, and fig. 12 a longitudinal section of a modification
of apparatus under my invention in which motion is given to the parts by means of
hydraulic power, in this case the die 2 is stationary, and the matrix 8 is separated
from the bed 1 and has to and fro motion imparted to it by the hydraulic rams 14
carried by the bed 1. Motion is given to the chair dies 3 by means of hydraulic
rams 16 carried by the sleeper dies 2.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
First. Inverted trough transverse sleepers having in combination with the main
body a the raised arch shaped ridge b, the chair jaws c and depressed portion d all
substantially as set forth.
Second. Machinery or apparatus consisting of dies matrix and jaws combined and
acting substantially in the manner and for the purpose set forth.
