Improvements in or relating to the Permanent Way of Railways.
I, SAMUEL YOUNG, of 93 Park Street, Peel Green, Patricroft, in the County of
Lancaster, Engineer, do hereby declare the nature of this Invention to be as
follows:-
My invention consists in certain improvements designed first, to prevent some of
the vibration and jarring caused when rolling stock passes over those parts of the
rails which are held in the chairs on the metal of which the rails usually rest,
secondly, to improve the joint between the adjoining ends of rails, and thirdly, to
prevent the wooden kevs from working out of their chairs.
The chief feature of my improvements consists in the construction, use and
application of chairs formed with recesses to receive blocks of wood or other suit-
able material upon which the bottom of the rails bed either directly or indirectly
as for example when certain forms of fish plates are employed. These chairs may
either be cast with metal sleepers or separately secured thereto or to ordinary
wooden sleepers but for each pair of joints I prefer to employ a combined sleeper
and chairs cast together in one piece of metal and to make the chairs of additional
length to receive the end of the rails. For greater security and to prevent injury.
to the wooden or other blocks I prefer to employ fish plates of clip form which
embrace the lower portions of the adjoining ends of the rails and bed upon the
wooden or other blocks in the chairs, but I may employ any other suitable form of
fish plate.
I complete the joint in each case by driving the usual wooden keys or other
suitable keys into the jaws of the chairs.
To prevent wooden keys from working out of their chairs I form on the jaw of
each chair a series of saw teeth or other suitably shaped teeth the points or cutting
edges of which point horizontally in the direction in which the key is driven and
so bed in the wooden key and prevent its withdrawal.

.I, SAMUEL YOUNG, of 93 Park Street, Peel Green, Patricroft, in the County of
Lancaster, Engineer, do hereby declare the nature of this Invention and in what
[Price 8d.]

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My invention consists in certain improvements designed first, to prevent some
of the vibration and jarring caused when rolling stock passes over those parts of
the rails which are held in the chairs on the metal of which the rails usually rest,
secondly, to improve the joint between the adjoining ends of rails, and thirdly,
to prevent the wooden keys from working out of their chairs.
The chief feature of my improvements consists in the construction, use and
application of chairs formed with recesses to receive blocks of wood or other suitable
material upon which the bottom of the rails bed.
To prevent the usual wooden keys from working out of their chairs I form on
the jaw of each chair a series of saw teeth or other suitably shaped teeth the points
or cutting edges of which point horizontally in the direction in which the key is
driven and so bed in the wooden key and prevent its withdrawal.
In the accompanying three sheets of drawings-
Figure 1is a transverse section, and Fig. 2 a side sectional elevation of my
improved chair with a rail keyed therein.
Figure 3 is a plan of the chair with the rail omitted.
Figure 4 is a side elevation, and Fig. 5 an end elevation, partly in section, of a
chair and fish plates for connecting the adjoining ends of a pair of rails.
Similar letters refer to similar parts throughout the several views.
I cast the metal chair with a pair of jaws 3 and 4 and with holes 5 for the
spikes, screws or bolts by which it is secured as usual on the sleeper, not shown,
and according to my improvements I also cast or otherwise form a recess 6 in the
chair and into this recess I drive a wedge shaped block of wood or other suitable
material 7. I also form on the jaw 4 of each chair a series of saw teeth or suit-
ably shaped teeth S, the points or cutting edges of which point horizontally in the
direction in which the wooden key 9 is driven and so prevent its withdrawal by
vibration. The rail 10 when placed in the jaws and secured therein by the key 9
beds upon the wooden block 7 which checks jarring and absorbs vibration.
In Figs. 4 and 5, I show my improved joint for the adjoining ends of each pair
of rails 10; the fish plates 11 are secured by bolts 12 to the rails and are shaped to
clip partly round the lower head of each rail; the chair is specially constructed to
fit over the lower portions of the fish plates and is provided with the recess 6 so
that when the block of wood or other suitable material 7 is driven into the recess
the rail 10 will be raised by the wedge shaped block 7 until the rail and fish plates
are all securely held in the chair. The joint of the rails is so arranged as just to
clear the block 7 on that side over which an approaching train would first pass,
as indicated by the arrow, Fig. 4, and in this manner of jointing there will be a
minimum of concussion when the rolling stock passes from one rail to another
and less wear on the permanent way and rolling stock.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The combination with a railway chair formed with a recess 6, of the wedge
shaped block 7 adapted to be driven into said recess substantially as herein set
forth for the purposes specified.
2. In combination, the railway chair formed with jaws and a recess 6, the wedge
shaped block 7 adapted to be driven into the said recess, the rail 10 bedding on said
block, and secured by the wooden key 9 in the jaws 3, 4, of which the jaw 4 is
provided with teeth 8 substantially as herein set forth for the purposes specified.
3. In combination, the railway chair formed with jaws to receive the rail and
fish plates and a recess 6. the wedge shaped block 7 adapted to be driven into said

page_text: recess,
the rail 10 bedding on said block and connected to the adjoining rail by the
fish plates 11 and bolts 12 substantially as herein described with special reference
to Figs. 4 and 5.
