We MARTIN EDWARD RIOU CRAWFORD of Chinchpoogly and DHUNJEEBHOY
FRAMJEE BANKER of Thakurdwar Road, Bombay, both in the Bombay
Presidency, India, Clerks in the office of the Agent, Great Indian Peninsula
Railway, Bombay, 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:-
In illustration of our said invention we have appended hereunto a sheet of
drawings to which reference is hereinafter made.
Of the figures in the said drawings—
Fig. 1 is a side elevation.
Fig. 2 is a plan.
Fig. 3 is a vertical section through x-x of Fig. 1.
Fig. 4 is an end elevation.
In all the figures the same letters of reference indicate the same parts.
Our said invention has for its object an improved construction of scotch-block
for use on railways for the purpose of arresting or retaining vehicles.
The body b of the scotch block has on one side claws or projections e engaging
with the rail a. On the other side are corresponding claws or projections c set so.
far out as to permit of the insertion of wedges or keys d between the claws c and
the web of the rail much in the same manner as rails are often secured in their
chairs. The wedges may be wood or metal or a combination of both materials.
The projections e and c may be formed integral with the body b or they may be:
separate pieces suitably secured thereto.

page_text: The number of claws may be varied and their inclines or those of the wedges
may be so disposed as that the wedges are secured by driving in the same direction
or in different directions. The latter mode is illustrated in the drawings and if
adopted the scotch block is not liable to become loose by a shock in one direction
only.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
1. A scotch block capable of attachment at any convenient place on the rail
substantially as set forth and shown.
2. A scotch block having on one side claws which engage with the rail and on
the other side other claws so shaped as to permit of the driving of wedges between
them and the rail for securing the scotch block thereto substantially as set forth
and shown.
