PROVISIONAL SPECIFICATION.
Improvements in Railway Sleepers and Chairs.
I JOHN WOODWARD of Ardgillan, Balbriggan County of Dublin, Ireland by
calling a land steward, do hereby declare the nature of this invention to be as
follows:-
:-
My invention consists of an inverted T shaped length of wrought iron, of suitable
proportions, to form when laid on its horizontal base, a sleeper, or if joined to form a
sphere, a sleeper and duplicate, two sleepers in one form, of a sectional inverted
T shape, throughout, and a flanged chair, as a necessary attachment, thereto, to be
saddled, on to the said sleeper, or sleepers, by removing, a necessary portion, of its
vertical section, or sections, leaving sufficient, to hold the saddled chair in its place, while
the flanges, of the chair, would continue, their own width, to the outer edge, of the
upper surface, of the horizontal base, of the said sleeper, or sleepers, being bolted
thereto, by suitable bolts, said and such arrangement, applies to reversible rails only,
while for flanged rails, a necessary portion, of the upper, or vertical section, of the
said sleeper, or sleepers is removed, as in the former case; for reversible rails, and a
similar portion, or slot, is removed, from each horizontal flange, of the rail, which
on being placed, to correspond, with the preparations in the upper, or vertical section,
of the said sleeper, or sleepers, drops down into its place, on to the upper surface
of the base, of the said sleeper or sleepers, the flange of the rail, is then bolted,
to the sleeper each side, and is then ready for traffic. I therefore believe 1 have
originated, the peculiar sleeper, or sleepers, and chair, and adapted their uses, to
the requirements, of every condition, of traffic on railways, and I seek, to protect,
said and such inverted T shaped wrought-iron sleepers, and chairs, and to have
perfected, the practical uses of iron, in place of wood, for railway sleepers.

Improvements in Railway Sleepers and Chairs.
.
I, JOHN WOODWARD, of Ardgillan, Balbriggan, Dublin, Ireland, Land Steward 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:
My invention consists of an inverted T shaped length of wrought iron of suitable
proportions to form when laid on its horizontal base a sleeper and a flanged chair as a
necessary attachment thereto; to be saddled on to the said sleeper or sleepers, by
removing a portion of its vertical section or sections leaving sufficient to hold the
saddled chair in its place. The flanges of the chair would continue their own width,
to the outer edge or flange of the upper surface of the horizontal base of the said
sleeper or sleepers being bolted thereto by suitable bolts. The said, and such arrangement
applies to reversible rails only, while for flanged rails a necessary portion of the upper
or vertical section of the said sleeper or sleepers, as in figure 2 marked A¹ and A², is
removed as in the former case for reversible rails, and a similar portion or slot is
removed from each horizontal flange of the rail which on being placed to correspond
with the preparation in the upper or vertical section of the said sleeper or sleepers,
drops down into its place on to the upper surface of the base of the said sleeper or
sleepers, the flanges of the rail are then bolted to the sleeper on each side and are then
ready for traffic. I therefore now proceed to describe the accompanying drawings
thereof, reference being had to letters and figures marked thereon, in order that my
Invention may be thoroughly understood.

page_text: Figure 1 represents a perspective view of the chair with the slots A formed on each
side and the saddle A³ at the base, for the purpose of being saddled on to the bridge A'
of the sleeper; and the sides A' of the tongue of sleeper T being embedded into the
slots A (up to the dotted lines indicated in the said figure 2.) of the chair.
The chair flange is provided with holes E for the purpose of being bolted to the
holes E of the flanged sleeper G.
The rail rides in the chair at B and is held secure therein by a wood or metallic pin
or bolt D, driven into the block to force the rail against the inside jaws of the chair
at C.
Figure 2. is a horizontal view of the T shaped wrought iron sleeper, with the
portion cut away to receive the chair as herein described.
According to my invention I adopt any suitable shaped sleeper, with the necessary
recess cut to receive the saddle of the chair, or in any combination thereof so as t,
form any desired shape or size, also the jaws of the chair may be formed of an
suitable shape to receive any description of rail, secured by the wood block and peg or
screwed bolt.
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 :-
:
First The combination of the T shaped wrought iron sleeper, cut to the desired
shape to receive the saddle of the chair, and the flanges of each to be bolted together,
constructed of any size or suitable shape, substantially as herein described and
according to the accompanying drawings.
Secondly: The chair with the jaws of any shape to receive the rail and block, with
the side slots A, and the saddle A³, at the base, to saddle on to the bridge A² of
the sleeper, and bolted together, substantially as herein described and according to
the accompanying drawings.
Thirdly: A wood peg or screwed bolt D to secure the block when the rail is
placed inside the chair on B thus combining in connection with said chair such
improvements as herein described and according to the accompanying drawings.
Dated this 4th day of October 1889.

Applicant.
