Improved Means for Süpporting and Retaining in Position the
Rails of Railways.
I, FRANCIS WALTER CLARKE, of 2 York Street, Nottingham, Publican, 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 has reference to and consists in certain improvements upon the one
described in the Specification of my Patent No. 20947 of the year 1892, and in
order that my present invention may the better be understood, I have appended
the accompanying sheet of drawings, referring to which,
Figure 1 is a side elevational view with rail in position.
Figure 2 a plan view taken on top of Figure 1, the "movable jaw" described
and shown in the Specification of my Patent of prior date hereto and above
identified, being in this view, removed, as is also the rail.
Figure 3 is an elevational view looking to the inside face of the fixed portion of
the chair already described in the Specification of my Patent No. 20947.
Figure 4 is a side elevational view of portion of a joint rail shewing slot therein
and the function of which in connection with the "studs," seen in Figures 1, 2
and 3, on the inner face of the fixed portion of the chair, will be hereafter defined.
Figure 5 is a detached end elevational view of the "movable jaw" of the chair
shewn in position in Figure 1.
Figure 6 is an elevational view looking to the inside face of the movable jaw of
the chair.
Figure 7 a longitudinal section taken on line a, of the plan Figure 2. Figure 8
being a transverse section taken on line c, d, Figure 2, and Figure 9 a detached
view of the locking key, such and for the purpose previously described in the
Specification of my Patent of prior date hereto.
In accordance with my present invention I still retain the salient feature
distinctive of the type of chair already described in the Specification of Patent
No. 20947 of 1892, namely that which consists of half or part chair A with
extended base and dovetailed or like slide or fillet pieces on one side as in the
drawings herewith Figures 1 and 2. Another half or part chair B (which I term
the movable jaw of my improved chair) having corresponding dovetail or equivalent
recess or recesses to engage those parts of the base so that this movable jaw B may
slide on the other part with immunity from vertical disengagement within certain
limits; and of a locking key or wedge, such as h. But in addition to all the fore-
going, I now in accordance with my present invention and with a view to imparting
enhanced strength security and reliability to the locking together of the fastening
device, increase the area of the dovetailed slide or slides i aforesaid and " "bridge
as at the keyway g, the bearing or grip of the key / becoming
proportionately increased. Also for rail joint chairs I provide the inner face of
the fixed jaw A with studs (two or more) e, which take into slotted holes f formed
at each of the meeting ends of the joint rails one of which is shewn Figure 4.
The two ends being adjusted in position within and against the fixed jaw A, the
movable jaw B is slid forward and secured in position substantially in the manner
described in the Specification of my previous Patent above referred to.

The studs e may be arranged to suit any special section of rail.

tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In supporting and retaining railway rails in position, the improvements
substantially as and for the purposes herein set forth.
Dated this 8th day of April 1895.
