Improvements in or connected with Tramrails.
I, HARRISON JACKSON, of Rose Cottage, Southport, in the County of
Lancaster, Tea Dealer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to prevent the "skidding" of the wheels of
vehicles upon tramrails, and the consequent wear and tear to rails and wheels and.
liability to accident.
It consists in forming the tramrail with suitable projections at suitable intervals,.
against which the wheel of any vehicle can strike, and by which it is lifted out of
the groove in the setts when the rail is below their level, and upon the rail when
the setts have sunk below the level of the rail.
These projections may be formed upon the rail itself, or separately, in the form
of spikes or pegs of suitable material and shape, which may be fitted into suitable
orifices in the rail, or, between the setts close to the side of the rail.

I, HARRISON JACKSON, of Gill Fold, Yeadon, in the County of York, (late of
Rose Cottage, Southport, in the County of Lancaster,) Tea Dealer, 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 my invention is to prevent the "skidding" of the wheels of
vehicles upon tramrails, and the consequent wear and tear to rails and wheels and
liability to accident.
It consists in forming the tramrail (the term tramrail including the central rail
or metal groove used for electrical and cable trams) with suitable projections at.
suitable intervals against which the wheel of any vehicle can strike and by which
it is lifted out of the groove whether caused by the sinking of the setts or rail or
by the wearing of the rail.
These projections may be formed upon the rail itself or separately in the form
of spikes or pegs of suitable material and shape which may be fitted into suitable
orifices in the rail, or between the setts close to the side of the rail.
Referring to the drawings sent herewith:-
Fig. 1 shows a perspective view of a suitable metal spike.
Fig. 2 shows a similar view of a tramrail showing the spike in position beside

page_text: Figs. 3 and 4 show two methods of indenting the rail so as to form projections
upon which vehicle wheels can strike.
In Fig. 1 the metal spike is provided with a head a consisting of two inclined
planes and a lang c. This metal tang o is driven into the chinks between the
sunk sette close up to the rail d (see Fig. 2) the inclined head a resting upon the
setts and forming a projection against which any skidding wheel must strike and
be lifted upon rail d this being assisted by inclined planes b.
In Fig. 3 the rail d is provided with curved indentations e upon its inner flange
forming curved projections 9 which answer the same purpose as the spike hend a.
In Fig. 4 the indentations are narrower and formed with square edges so as to
enable the wheel of a vehicle to run along them upon the rail without shake, but
forming projections i which lift the wheel directly it commences to skid along the
side of the rail.
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 :-
:-
Forming or fitting, upon, or to, a tramrail suitable projections, either attached
or separate, to prevent the skidding of other vehicle wheels along the same,
substantially as described hereinbefore and in the accompanying drawings.
