NEW OR IMPROVED APPLIANCES FOR THE RAILS OF RAILWAYS FOR STOPPING OR RETARDING TRAINS OR CARRIAGES, SPECIALLY APPLICABLE TO SIDINGS
Year: 1876

page_text: LETTERS PATENT to David Jones, of Inverness, in the County of Inverness,
North Britain, Mechanical Engineer, for the Invention of "NEW OR IMPROVED
APPLIANCES FOR THE RAILS OF RAILWAYS FOR STOPPING OR RETARDING TRAINS
OR CARRIAGES, SPECIALLY APPLICABLE TO SIDINGS."
Sealed the 8th May 1877, and dated the 16th November 1876.
PROVISIONAL SPECIFICATION left by the said David Jones at the Office
of the Commissioners of Patents on the 16th November 1876.
DAVID JONES, of Inverness, in the County of Inverness, North Britain, Mechanical
Engineer. "NEW OR IMPROVED APPLIANCES FOR THE RAILS OF RAILWAYS
FOR STOPPING OR RETARDING TRAINS OR CARRIAGES, SPECIALLY APPLICABLE TO
SIDINGS."
The object of this Invention, which I term the "Railway Siding Guard," is, as
this name implies, providing security for vehicles placed in sidings, and consists of
brackets or lugs bolted to a rail where required, to which brackets or lugs is hinged
a stop or derailing block or plate. This block or plate is so designed that, supposing
a vehicle to be impelled against it with unusual force, the flange of the wheel comes
against a flange in the said block or plate placed in such a way that the wheel
mounts it, the result being that the vehicle is immediately derailed, and thus
effectually prevented from leaving the siding; but with the application of not more
than ordinary force the vehicle is stopped without any derailment. Or the flange
may be constructed that the wheel will pass over it and the vehicle be stopped
without being derailed, although unusual force be applied.
.
The block or plate when across the rail can be secured with lock and key, and
when opened for the ingress and egress of vehicles does not offer any obstruction, as
no part of it need be above the level of the rail.
The brackets or lugs and block or plate may be made of steel, iron, or any other
suitable material, and can be used on either the right or left rail, as is most con-
venient.
This Invention, by its simplicity of construction, its cheapness, and the safety it
affords, gives great advantages over the existing chock blocks.

The object of this Invention, which I term the "Railway Siding Guard," is, as
this name implies, providing security for vehicles placed in sidings, and consists of
brackets or lugs bolted to a rail where required, to which brackets or lugs a stop or
derailing block or plate is hinged. This block or plate is so designed that, supposing
a vehicle to be impelled against it with unusual force, the flange of the wheel comes
against a flange in the said block or plate, placed in such a way that the wheel
mounts it, the result being that the vehicle is immediately derailed, and thus
effectually prevented from leaving the siding; but with the application of not
more than ordinary force the vehicle is stopped without any derailment. Or the
flange may be so constructed that the wheel will pass over it and the vehicle be
stopped without being derailed, although unusual force be applied.
The block or plate when across the rail can be secured with lock and key, and
when opened for the ingress or egress of vehicles does not offer any obstruction, as
no part of it need be above the level of the rail.
The brackets or lugs and block or plate may be made of steel, iron, or any other
suitable material, and can be used on either the right or left rail, as most con-
venient.
This Invention, by its simplicity of construction, its cheapness, and the safety it
affords, gives great advantage over the existing chock blocks.
Having thus described the nature of the said Invention, and intimated in general
terms in what manner the same is to be performed, I will now proceed (aided by
the accompanying Drawings) to further and particularly describe and ascertain
in what manner the same is to be performed or carried out in practice, that is
to say,-
DESCRIPTION OF THE DRAWINGS.
Figs. 1 to 4 (Sheets 1 and 2) show (in plan, clevations, and section) my new or
improved appliances.
A is an ordinary rail; B, B, brackets or lugs fastened to rail A, as shewn; C is a
washer plate, which has a projection on it to receive a hasp on block or plate D, and
to secure it by lock and key; D is the stop or derailing block or plate hinged to
brackets or lugs B, B, by bolt E; F, F, are flanges to guide wheel flange to stop G.
Having now particularly described and ascertained the nature of the said Invention,
and in what manner the same is to be performed or carried out in practice, I hereby
declare that I claim the Invention of "New or Improved Appliances for the Rails
of Railways for Stopping or Retarding Trains or Carriages, specially applicable to
Sidings," substantially as herein-before described and illustrated by the Drawings,
the "Railway Siding Guard" herein-before set forth and described being the
important point or feature thereof.
In witness whereof, I, the said David Jones, have hereunto set my hand and
and seal, this Eighth day of May, in the year of our Lord One thousand eight
hundred and seventy-seven.
