Complete Specification Left, 20th Apr., 1900-Accepted, 26th May, 1900
Improvements in the Rail Joints of Tramway Permanent Ways
and in Securing Rails to Underbed.
I, WILLIAM HOWARD-SMITH, of Donington House, Norfolk Street, Strand, in
the Adminstrative County of London, Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the rail-joints of tramway permanent ways, the
object being to re-inforce the fish plate joints at present in use.
To this end I provide each joint with a sole-plate about twice the length of
the fish-plate and made of T or channel shape with the top flange equal or about
equal in width to the foot or flange of the rail.
These sole-plates are placed in position at the rail joints and the rails secured
thereto by bolts, or other suitable fastening devices, after which the concrete,
cement, or other material of which the rail bed is made is filled in, and in this
way the sole-plates also form substantial anchor plates to the fish-joints.
Dated this 19th day of July 1899.

Improvements in the Rail Joints of Tramway Permanent Ways
and in Securing Rails to Underbed.
I, WILLIAM HOWARD-SMITH, of Donington House, Norfolk Street, Strand, in
the Administrative County of London, Civil Engineer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to
particularly described and ascertained in and by the following statement:-
This invention relates to the rail-joints of tramway permanent ways, the
object being to re-inforce the fish plate joints at present in use, and to anchor
the rails to the concrete underbed.
To this end I provide each joint with a sole-plate about twice the length of
the fish-plates and made of T or channel shape with the top flange equal or
about equal in width to the foot or flange of the rail.
These sole-plates are placed in position at the rail joints and the rails secured
thereto by bolts or other suitable fastening devices, after which the concrete,
cement or other material of which the rail bed is made is filled in, and in this
way the sole-plates form substantial anchor plates of the rails to the underbed.

page_text: In the accompanying drawings forming a part of this Specification,
Fig. 1 is an elevation showing the ends of two girder tramway rails secured
together by fishplates and firmly bolted to the sole-plate or device embodying
this invention; Fig. 2 is a vertical section of same shown in position in the
rail bed; and Fig. 3 is an isometrical projection of the sole-plate. The same
parts are lettered to correspond in all three figures.
In these drawings the letters A A represent the ends of the girder tramway
rails, B B the fish-plates at the joints, U the top flange, D the web, and E
the bottom or anchor flange, of the sole-plate. The sole-plate is secured by its
top flange C to the foot or flange A¹ of the rails, by the bolts, nuts and washers
or other suitable fastening devices F, the rails are then laid in position and
the concrete, cement or other material G of which the rail bed is made is filled
in and when set the sole-plate becomes keyed to the rail bed and forms a sub-
stantial anchor of the rails.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
(1) In rail joints of tramway permanent ways secured by fish plates, a sole-
plate of Tor channel shape and of about twice the length of the fish plate
firmly secured to the foot or flange of the adjacent ends of the rails so as to
reinforce the joint and anchor the rails to the rail bed, substantially as described.
(2) In fish plate joints of tramway permanent ways an anchor sole-plate bolted
to the lower part of the rail ends and embedded in the concrete, cement or other
rail bed, substantially as and for the purpose herein before described and illus-
trated in the accompanying drawings.
