An Improved Tram Car Ramp for De-railing and Re-railing Cars.
NATHANIEL PALMER, 76, Fetter Lane, Holborn, E.C., China & Glass Repairer,
do hereby declare the nature of this invention to be as follows:-
The ramp is made of iron and consists of a flat plate with rod on under side to
fit in groove of tram rail, and two brackets on top side of plate for guiding
purposes. The same ramp will de-rail and re-rail the car. I think it will be a
very useful thing as it is easily adjusted to the rails and can be carried with every
car. It will also save time, trouble, and strain to the horses.

NATHANIEL PALMER, 76, Fetter Lane, Holborn, E:C., China and Glass Repairer,
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: -
This invention has for its object to facilitate de-railing and re-railing tram cars
by means of an improved ramp whereof the accompanying drawings shew top and
bottom plan views, Fig. 1, being a bottom, and Fig. 2 a top view. Similar letters
of reference indicate corresponding parts.
Such ramp consists of an iron plate (a) of any convenient form, having an under
rib (b,) cast thereon which fits in the socket of the tram rail and so keeps the
ramp in position. The ends of such under rib project beyond the plate, one
end (6) being recessed to form a scoop for clearing out the rail socket, while the
other end (62), and likewise the corresponding end of the plate, are grooved to
form an inclined way to lead the car wheel in the desired direction. Guides (c)
are cast on the top of the plate to prevent the wheel running off the ramp laterally.
To de-rail the car the grooved end of the ramp is placed on the rail in front of
the wheel and the under rib is inserted in the rail socket. The wheel is then led
through the groove (62) on to the ramp thereby de-railing the car. To re-rail
the car the broad end of the ramp is placed on the rail in front of the wheel and the
under rib inserted in the rail socket. The wheel is then run on to the ramp, the
edge whereof is bevelled off to facilitate the wheel passing over the same, after
which the wheel is led into the groove (62) and thence into the rail socket, thus
re-railing the car. A hole may be cast in the ramp so as to hang it on the car.

page_text: My improved ramp economises both time and labour, and enables the operations
of de-railing and re-railing to be performed with ease and certainty.
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:-
1. A tram car ramp consisting of a plate provided with an under rib having
recessed and grooved projecting ends, and furnished with suitable guides, all
substantially as hereinbefore described and shewn.
2. The improved tram car ramp substantially as hereinbefore described and
shewn.
