IMPROVED MOVEABLE POINTS
Year: 1884

page_text: I MAURICE PHILLIPS Wheelwright and Blacksmith of the Bull Stake Darlaston
in the County of Stafford do hereby declare the nature of my invention for
IMPROVED MOVEABLE POINTS to be as follows:-
The pin on which the tongue moves will be placed at the entrance and not at the
heel of the point which will allow the tongue to be shorter and stronger. The
tongue will be moved from one side to the other by a screw lever connected to a
wheel at the side, The screw lever to work in the bottom of the tongue in
a groove so that when the wheel is turned the screw forces the tongue from one
side to the other and keeps it in its proper position.

I MAURICE PHILLIPS of the Bull Stake Darlaston in the County of Stafford
Wheelwright and blacksmith do hereby declare the nature of my invention for
IMPROVEMENT OF MOVEABLE POINTS FOR TRAM AND RAILWAYS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
I construct a moveable radiating tongue having its seat on the metal of the point
casting or forging and I place the centre pin on which such tongue radiates at the
toe or entrance end of the point instead of at the heel as is the present practice
by which means I obtain a tongue of much shorter length and a consequently
narrower and shorter gap in the road. The tongue I make with longitudinal
flanges having bevelled edges in the direction of the sides of the point and in the
tongue bed of the point I make similar edges bevelled in an opposite direction
dividing such edges at intervals with angular pieces or points the object of which
is to clear away any refuse or rubbish that may have accumulated.
On the underside of the tongue I construct a grove into which works an acting
piece constructed so as to be of similar form to one thread of a worm or screw.
This worm or screw is fixed on the end of a bar which bar is extended under the
rail and has its further end carried in a box outside the point being secured by a
lock nut or other suitable means. On the same bar carrying the screw or worm is
fitted a disc having a recess for the reception of the actuating lever. The mode of
action being that the lever is inserted into the recess in the disc and pushed over
thus causing the worm to revolve so far as shall be necessary to throw the tongue
over to the required new position.
The tongue is secured against rising by means of a projecting nib which goes
under a rabate made in the casting or forging of the point body and at the toe end by
a projecting lappet receiving a pin which pin passes through the lappet and through
the body of the point casting or forging. It is thus only necessary to remove this
last mentioned pin in order to take out the tongue for repairs or other requirements
and can be done without any removal of the ballast or surrounding pavement.
And further to explain my invention I proceed now to make explanation of
Drawings required after sending complete Specification.
T T. T. (Ground Plan, Transverse & Longitudinal Sections) is the "Tongue"
mentioned in Specification.
C. (Longitudinal Section) is the "Centre Pin" on which the Tongue radiates.
F. F. (Ground Plan & Transverse Section) are the "Bevelled Flanges" with
angular Pieces at intervals.
A. A. A. (Ground Plan, Transverse & Longitudinal Sections) is the " Actuating
Screw Lever."
D. (Ground Plan, Transverse, & Longitudinal Sections) is the "Disc."

P the "pin" passes to prevent Tongue rising.

page_text: 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
1st The placing of the radiating Pin or Centre at the toe or Entrance end of
the Point tongue.
2nd The actuating Screw and Lever Diso substantially as described herein.
3rd The method of securing the moveable tongue in its position in the point
casting or forging.
4th The bevel flanges on the sides of the moveable tongue and point body.
