PROVISIONAL SPECIFICATION.
Improvements in Railway Chairs.
HENRY MOULD 6 Lewes Place Seaside Road Eastbourne Sussex Builder do hereby
leclare the nature of this invention to be as follows:-
And its design in making it in two parts and fitting together to form one solid
Chair.
1st. Flange B consolidated in and on slide F as shown on dotted line. E. F forms
hearings on each side of slide and the result of Bolt passing through Flange B
securely fastens & combines the end of chair at Flange B.
2nd. Flange B consolidated to slide F forms one complete part and secured by bolt
through Flange A.
3rd. Slott G as formed in slide F as shown on dotted line E. F placing its position
when adjusted under Flange A forms expansion to line of Rail.
4th. Figure H. on dotted line shewn on section A & B shews intersecting line of
chair when closed in channel.
5th. Section on dotted line, I & K shewing outlines and end of chair when
closed, Figure L on horizontal lines shews end section of slide in channel.
The features of my Invention embraces practical ideas in the following remarks.
1st. In its construction it is adapted to firmly fix the Rail without wedge and
is applicable for ordinary use Figure G shewing slott allowing expansion to Rail.
2nd. Its design in framing it in two separate parts affords economy in the
following manner, viz. If by accident one flange or one half chair be broken or
damaged the bolts can be drawn, and the part restored by application of the part
required without disturbance to the line of Rail.

COMPLETE SPECIFICATION.
Improvements in Railway Chairs.
HENRY MOULD 6 Lewes Place Seaside Road Eastbourne Sussex Builder 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 "improvement in Railway Chairs" consists of forming the cast iron
chair to receive the Rail in two parts, so formed that the one portion slides into the
other and when fixed on the sleeper securely locks the Rail in its jaws without the
intervention of wedges or other fasteners.
The annexed two sheets of Drawings will more fully explain the nature of my
Invention. On sheet No. 1, figure 1. shews a longitudinal section (3rd real size)
through the middle of the chair, Figure 2. the chair on plan, and figure 3. is a transverse
section through the centre.
On sheet No. 2. the said chair is shewn apart to more clearly shew its construc-
tion.
Figures 4 & 5 show respectively an elevation & plan of one part, A. and Figures 6 & 7.
respectively, an elevation and plan of the other part, B.
A. is one half of the chair secured to the sleeper in the usual way, the Rail is
then inserted and the other half B. is then passed under, into its place closing its jaw
on the Rail, and when fixed to the sleeper in the usual manner by spikes or bolts in
the holes, C. consolidates the whole as one.

page_text: To allow a little latitude in fit between the chair and Rail for variations in gauge
of Rail or on curves the hole C. 2, in the B portion is slightly oval, as also the hole
in A. for the bolt D. This bolt D is not absolutely necessary, but may be used as a
safeguard where very heavy traffic is concerned:
It will be seen by the Drawings on sheet 2. that there is a wide recess E under
the portion A, and a corresponding projection F. on the part B. and with the further
view of preventing. lateral strain, on this portion, or on the Bolts, projection on the
parts A. marked G. interlocks into similar recesses in B.
It is obvious by my Invention; that when in position the chair is equally strong
as a solid one, with the further advantage that, the use of wedges (very liable to work
loose) is avoided to the improvement of the permanent way, and should a breakage
occur only half of the chair is spoiled.
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,
.
1st. The construction of Railway chairs in two portions, so made to interlock each
other and securely grip the Rail between its jaws, without the use of wedges or any
other fastening.
2nd. The method of so fixing the said Chair to the sleeper that the fixing Bolts to
the sleepers, secures the two portions together independent of any other Bolt or
fastening substantially as hereinbefore described.
