We WALTER DICKINSON of Providence Place, Bridge Street, Morley, Manu-
facturer, and JOSEPH HIBBERT of St Andrews Place, Bradford Manufacturer, both
in the County of York do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to dispense with the ordinary "key" used for
securing rails in railway chairs, such "key" now frequently requiring attention on
account of its shaking loose, and thus interfering with the safety of the traffic.
The chair is of ordinary construction; and in the space where the ordinary
"key" is passed we insert loosely a metal block shaped at the back to suit the
form of chair, and flanged so that the projecting part of chair may fit into it. The
bottom part of the front of the block, or that nearest the rail, fits onto the swell at
the bottom of the rail, and the upper vertical portion thereof is made flat and
roughed on the face, or provided with small projecting pieces thereon.
Between the rough face of the block and the rail, a wood packing is driven
tightly, and held there by the rough face or projecting pieces. By this means not
only is the rail held at the upper portion but also the swell on the lower part of
the rail is gripped by the lower part of the metal block, thus the rail is held firmly
in position and without any danger of shaking loose.
There is a groove in back of metal block to receive a wedge which may be
driven in between such block and the chair whereby the fastening of the rails is
made more secure than heretofore.

Improvements in Means or Apparatus for Securing Rails in
Railway Chairs.
We WALTER DICKINSON of Providence Place, Bridge Street, Morley, Manu-
facturer and JOSEPH HIBBERT of St Andrews Place Bradford, Manufacturer, both
in the County of York 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 :-
The object of our invention is to dispense with the ordinary key used for securing
rails in railway chairs such "key" now frequently requiring attention on account
of its shaking loose and thus interfering with the safety of the traffic.
Fig. 1 is a perspective view shewing chair and rail with my apparatus applied.
Fig. 2 is a transverse section. Figs. 3 and 4 are respectively perspective views of
metal block.
The chair A is of ordinary construction and in the space where the ordinary key
is passed we insert a metal block B shaped at the back C to suit the form of the
chair, and flanged at E so that projecting part F of chair may fit into it.
The bottom part G of the front of the block B may be made to fit onto the
swell H at the bottom of the rail I as shewn, or formed so as to clear it as shewn
by dotted lines.
The upper vertical portion J of the block B is made flat and roughed on the face
or provided with small projecting pieces K thereon as shewn at Figs. 2 and 4.
Between the face of the block B and the rail I a wood packing L is driven
tightly and held there by the roughed face or projecting pieces K. By this means
not only is the rail I held at the upper portion, but also the swell H on the lower
part of rail is gripped by the lower part of the metal block B, thus the rail I is held
firmly in position and without any danger of shaking loose.
When preferred we provide a groove M in back of metal block B as shewn at
Fig. 3 to receive a wedge which may be driven in between such block and the
chair whereby the fastening of the rails I is made more secure.
Having now particularly described and ascertained the nature of our said
invention and in what manner the sámé is to be performed, we declare that what
we claim is :-
The arrangement, construction and application of metallic block B roughed on
the face or provided with projections K in combination with wood packing L
applied within ordinary chair A, substantially as herein set forth.
