1, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester
both in the County of Lancaster, 118 New Street, Birmingham in the County of
Warwick and 322 High Holborn in the County of Middlesex, Civil Engineer, 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 a device by means of which the points may be
switched or moved from the locomotive or carriage, and is intended to avoid
accidents arising through the forgetfulness or neglect of the signalman, and also to
dispense with the use of a pointsman.
In the accompanying drawing :-
Figure 1 is a longitudinal section of the point shifting or moving device, showing
the construction of the points;
Figure 2 is a plan view of the same;
Figure 3, an end view;
Figure 4, a plan view of the point mechanism.
The automatic point shifting device consists essentially of four parts, viz. :-the
point tongue A, the lever shifting mechanism po' oc D and D', a slide piece F with
a roller E attached thereto, and finally a switching lever G.
The tongue A movable on a pivot a is arranged at the junction with the main
track, and according as the said tongue is moved to either one side or the other,
connection will be made with either the part B of the track or with the branch
track C.
The automatic movement of the tongue A takes place in the following
manner:
A short piece of double tracks is attached to the point of the tongue A, and is
adapted to be moved to and fro across the rails by means of a bar p, elbow
lever o, o and drawbar or link c. To this end the drawbar c is connected by
means of a bolt d with an arm e of an elbow lever D, and also by means of a
link with an arm el of an elbow lever D'. These levers D D₁ are pivoted on
the track as shown and according as either the lever D or D' is depressed, so will
the link c be moved forward or backward. The elbow lever o o¹ will thus be
turned on its fixed pivot y and will move the arm p endwise which latter will push
the double track pieces to one side or the other across a suitable foundation
plate having an elongated groove q' in which works a bolt g attached to the
double track piece s. The tongue A being connected with the pieces will be
accordingly moved to one side or the other.
The depression of the levers D or D' takes place as follows:-
A roller or wheel E is mounted in lugs or bearings on a slide F arranged to
move transversely of the vehicle in brackets K fixed to the under part of the
lucomotive or carriage. The slide piece F may be pushed to one side or the other,

page_text: during the journey, either from the locomotive cr carriage, by means of a handle
or switch lever G on one end of a spindle H, and a lever I, also mounted on said
spindle and carrying a bolt g, which is arranged between projections and ¹
attached to the slide. The roller E carried by the slide piece F may thus be
moved to either side to ride over the lever D or the lever D¹ and thereby move the
tongue A to either one side or the other in the manner herein before described.
When the turning or moving of the points has been completed, the apparatus may
be fixed or locked by means of the handle G.
The slide piece F carries a pin l which engages between angle pieces L L', and
a spring is placed round said pin in order to keep the slide piece F pressed down
whilst allowing it a little vertical play.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is
1. A device for switching or moving the points of railways, tramways and the
like, characterised by a movable tongue (A) connecting cither with the main
track (B) or branch track (C) on levers (D or D¹) being depressed, said
levers (D or D¹) pushing forward or backward lever arms (e and e¹) and moving
the tongue (A) on the pivot (a) to the right or left substantially as herein before
described and shown in the accompanying drawing.
2. A device for switching or moving the points of railways, tramways and the
like, consisting of a slide piece (F) for effecting the depression of the levers (D or D¹)
said slide piece being arranged on the under part of the locomotive or carriage and
carrying a movable roller (E), said slide piece (F) and roller (E) being adjusted
and fixed by means of a lever (G), the bar or rod (H) of which carries a lever (I)
having a pin (9) engaging between the projections ( and h¹) of the said slide
piece (F) substantially as herein before described and shown in the accompanying
drawing.
