Improvements in Shoes, Sole Plates, or Chairs for the Support of
Vignoles Rails, and in the Manufacture thereof.
We, JONATHAN PACKMAN, RICHARD POPKISS, and EDWARD HEASMAN, all
of Suffolk House, Laurence Pountney Hill, in the City of London, Consulting
Engineer, do hereby declare the nature of our invention to be as follows:-
This invention relates to improvements in shoes, sole plates, or chairs for the
support of vignoles or flange rails, and in the manufacture thereof, and has for its
object the construction and arrangement of such a device whereby the support of
the rail upon its sleepers is effected in a simple, cheap and thoroughly efficient
manner.
Our invention firstly consists in the form of the shoe, soleplate, or chair, and
secondly in the method of manufacture of the same.
To carry our invention into effect we form the shoe preferably of malleable iron
or mild steel rolled of a specific section, which is that of a plate with two ribs or
projections normal to the plate spaced at such a distance apart as to allow of the
flanges of the rail being placed between. The bar of this section is cut up into
pieces of the proper length to form shoes to support the rails at each sleeper. The
portion of the shoe between the ribs or jaws is of taper form to allow of the proper
cant being given to the rail.
The ribs are bent down towards one another in order to form jaws between
which the flanges of the rail are held by keys in the manner adopted in steel
sleepers with bent punched-up clips.
This bending of the ribs may be effected by passing the bar after its formation
with ribs normal to the surface, through rolls that turn the ribs towards one
another to form clips, the bar being subsequently cut into shoes. Or equivalently
the shoes may be cut off and the clips of each one be pressed down by hydraulic or
other pressure; this method is preferable when taper keys are used, as the propèr
relative angular disposition of the clips can be readily effected.
These shoe plates can be rivetted to metallic sleepers or they can be spiked down
or secured by fang bolts to wooden sleepers, and in either case the upper surface of
the sleeper can be left as a plane, the required tilt of rail being given by the
angular bed of the shoe on which the flange of the rail rests, and thus the usual
camber of the metallic sleeper or the sunk inclined bed for the plates on the wooden
sleeper are entirely dispensed with.
If desirable the clip may be corrugated to prevent the keys working loose.

Vignoles Rails, and in the Manufacture thereof.
We, JONATHAN PACKMAN, RICHARD POPKISS, and EDWARD HEASMAN, all
of Suffolk House, Laurence Pountney Hill, in the City of London, Consulting
Engineers, 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:-
This invention relates to improvements in shoes, sole plates or chairs, for the
support of vignoles or flange rails, and in the manufacture thereof, and has for its
object the construction and arrangement of such a device whereby the support of
the rail upon its sleepers is effected in a simple, cheap and thoroughly efficient
manner.
Our invention firstly consists in the form of the shoe, sole plate or chair and
secondly in the method of manufacture of the same.
And in order that our invention may be the better understood I now proceed to
describe the same with reference to the drawings hereto annexed and to the letters
and figures marked thereon.
Figure 1 is a sectional elevation showings rails supported by our improved chair
upon a steel or other metallic sleeper.
Figure 2 is a plan of the same.
Figures 3 and 4 are similar views of our chair attached to wooden sleepers by.
fang bolts.
Figure 5 shows the sectional view of the bar from which our chairs are made.
Figure 6 is a view of a corrugated key for securing our rail within the chair.
Figure 7 is an enlarged view of the rail supported in the chair.
To carry our invention into effect we form the shoe A preferably of malleable
iron or mild steel rolled to a specific section as shown in Figure 5 from which it
will be seen to be that of a plate with two ribs or projections B B normal to the
plate and spaced at such a distance apart as to allow of the flanges of the rail C
being placed between the ribs or projections B B as shown in Figures 1, 2, 3, 4
and 7.
The bar of this section (Fig. 5) is cut up into pieces of the proper length to form
the shoes A which support the rails at each sleeper.
The portion of the shoe E situated between the ribs or jaws B B is of tapered
form or section to allow of proper cant being given to the rail when forming part
of the track.
The ribs B B are bent down toward one another from the section shown
in Fig. 5 to that shown in Fig. 7 in order to form jaws between which the flanges
of the rail C are held by keys D in the usual manner adopted in steel sleepers with
bent punched up clips. This bending or setting of the ribs B to form jaws may be
effected by passing the bar (after its formation with ribs normal to the surface as
shown in Fig. 5) through rolls that turn the ribs toward one another to form clips,
the bar being subsequently cut into shoes. Or equivalently the shoes may be cut
off from the bar and the clips of each one may be pressed down by bydraulic or
other pressure; this method is preferable when tapered keys are used as the proper
relative angular position of the clips can be readily effected. These shoe plates A
can be rivetted or bolted to metallic sleepers as shown in Figs. 1 and 2 or they can
be spiked down or secured by fang bolts or other fastenings to wooden sleepers as
shown in Figs. 3 and 4 but in either case the upper surface of the sleeper can be
left as a plane by reason of the fact that the required tilt of the rail is given by the

page_text: angularly disposed bed of the shoe on which the flange of the rail rests and thus
the usual camber of the metallic sleeper or the usual sunk inclined bed for the
plates on the wooden sleeper are entirely dispensed with.
If desirable the clips may be corrugated and fitted with corrugated keys as
shown in Figure 6, in order to prevent the keys working loose.
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1st. A shoe, sole plate, or chair for the support of vignoles or flange rails having
an upper supporting surface upon which the flange of the rail rests angularly
disposed to the under-surface which rests upon the sleeper in combination with
means for securing the rail to the shoe, sole plate, or chair, substantially as
described.
2nd. A shoe, sole plate or chair, for the support of vignoles or flange rails having
an upper supporting surface, upon which the flange of the rail rests, angularly
disposed to the under-surface which rests upon the sleeper in combination with
clips formed thereon or integral therewith and a key adapted to hold the rail
tightly by its flanges.
3rd. The method for the manufacture of shoes, sole plates or chairs for the
support of vignoles or flange rails consisting of the rolling of malleable metal into
a bar having ribs normal or approximately normal to the surface upon which they
are situated, the subsequent bending over of the said ribs into angularly disposed
clips, and the cutting up of the bar into lengths, either before, or after the bending
operation to form shoes, sole plates, or chairs, substantially as described and
illustrated with reference to Figures 5 and 7 of the accompanying drawings.
