AN IMPROVED CONSTRUCTION OF RAILS FOR RAILWAYS AND IN MEANS OF FASTENING SAID RAILS IN CHAIRS
Year: 1884

I ALBERT EVAN ADLARD of 33 Guildford Road, South Lambeth, Surrey, Tram-
way Engineer, do hereby declare the nature of my said invention for "AN
IMPROVED CONSTRUCTION OF RAILS FOR RAILWAYS AND IN MEANS OF FASTENING
SAID RAILS IN CHAIRS" to be as follows:-
The object of this invention is to construct railway rails that the lower ends
will admit of their being forced down channels in the chairs and then to spring or
engage under lips or shoulders as to hold themselves in place.
For the purpose of my invention I form the web of the rail tapered or thinner
at the lower end or at the centre of its depth than the upper part and a bulb or
projection on the lower end, said projection being preferably on both sides so that
it will engage in either side channel of the chair to hold itself in place.
The chair has a shaped upper part and a rather wide slot of such a depth as to
allow of the head of the rail resting on the tops of the chair at each side of the
slot. The bottom of the slot is undercut for the reception of the bulb of the rail
into which it springs when forced home.

way Engineer, do hereby declare the nature of my said invention for
"AN
IMPROVED CONSTRUCTION OF RAILS FOR RAILWAYS AND IN MEANS OF FASTENING
SAID RAILS IN CHAIRS," and in what manner the same is to be performed to bo
particularly described and ascertained in and by the following statement :-
The object of this invention is to construct railway rails that the lower ends
will admit of their being forced down channels in the chairs and then to spring or
engage under lips or shoulders so as to hold themselves in place.
For the purpose of my invention which I clearly show in the annexed drawings
Figure 1, I form the web A of the rail B tapered or thinner at the lower end or
at the centre of its depth than the upper part, and a bulb or projection C on the
lower end, said projection C being preferably on both sides so that it will engage
in either side channel of the chair D to hold itself in placo as seen at Figure 2.
The chair D has a shaped upper part E and a rather wide slot F of such a depth
as to allow of the head B of the rail resting on the tops G, H, of the chair D at
each side of the slot. The bottom of the slot is undercut for the reception of the
bulb C of the rail into which it springs when forced home.
The rail B somewhat resembles the bull-headed section, with a narrow web A,
and a base C of bulb form. In adjusting the rail in the chair, the web A is
slightly sprung as the bulb C passes down the slanting slot F between the jaws of
the chair D; the head of the rail then takes a rectangular position with the head
of the chair, and is fairly home. The chairs can be positioned alternately, having
the slot in opposite directions. It will be observed that the rail rests upon the
face G of the outside jaw, and on the seat H of the inside jaw; the object in having
the seat away from the cheek of the rail is to prevent bulging in that part.
The rails are jointed in the chairs, and requiro no fish-plates.
It need hardly be pointed out that the cost of repairing the permanent way
under the existing system is enormous; and it is obvious that the staff and
expenses would be considerably reduced by the use of my improved rail.
In my invention there is no possibility of rattle, as the rail maintains both a
vertical and outward spring against the chair, neither are bolts, keys, trenails, or
other fasteners required to connect it to the chains.
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
First. The improved construction of railway rail as shown at Figuro 1 of the
annexed drawings, said rail baving a web and lower bulb as and for the purposes
set forth.

page_text: Secondly. The construction of railway rails and the method by which they are
connected to chairs without bolts, keys, or other fasteners as described with
reference to Figure 2 of the annexed drawings.
