LOCKING RAILWAY CARRIAGE DOORS WHILE IN MOTION
Year: 1884

page_text: I THEOPHILUS ADINO MILO 70 The Grove, Camberwell S.E. Gentleman, do
hereby declare the nature of my invention for LOCKING RAILWAY CARRIAGE
DOORS WHILE IN MOTION to be as follows :-
To prevent accidents occurring through the opening of railway and other
carriage doors while the carriage is in motion and to prevent the throwing of
persons or bodies from carriages while.in motion.
The invention consists in adapting to the carriages certain improved apparatus
whereby every carriage door after being closed will be securely fastened until the
carriage is again brought to a standstill when the doors can be opened in the
ordinary manner.
In carrying out this invention I place under each carriage door an apparatus
consisting of a wheel or box containing movable rods which when not in motion
fall into the said wheel or box on the upper part, but which when the said wheel
or box is set in motion by a band or cord connected with the axle of the carriage
wheels fly out to their extreme allowable length. Underneath the floor of the
carriage and balanced by movable weights or springs I place a rod or bolt which
passes through a tube or hole in the floor and enters a hole or tube in or attached
to the lower part of the door when the carriage is in motion, this rod or bolt having
curved plates or bars attached which are acted upon by the movable rods in a way
hereinafter described. The action of the apparatus is as follows. When the carriage
is in motion the wheel or box is set in motion by the band or cord connected with
the axle of the carriage wheels, the movable rods fly out to their extreme allowable
length the curved plates or bars are released, and the rod or bolt to which they are
attached passes through the tube or hole in the floor into the hole or tube in or
attached to the lower part of the door which is then securely fastend. When the
carriage is brought to a standstill the movable rods fall into the wheel or box on
the upper part, pulling down the curved plates or bars attached to the bolt causing
the bolt to drop and thereby releasing the door which can then be opened in the
ordinary way. The special feature of my invention is the use of a wheel or box
containing movable rods whereby the carriage doors are fastened and unfastened.

page_text: I, THEOPHILUS ADINO MILO 70 The Grove Camberwell S.E. Traveller do
hereby declare the nature of my invention for LOCKING RAILWAY CARRIAGE
DOORS WHILE IN MOTION 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 this invention is to prevent the accidents that are continually
occurring through the opening of railway and other carriage doors while the
carriage is in motion and to prevent the throwing of persons or bodies from the
carriage while in motion.
The invention consists in adapting to the carriages certain improved apparatus
whereby every carriage door after being closed will be securely fastened until the
carriage is again brought to a standstill when the doors can be opened in the
ordinary manner.
In carrying out this Invention I place under each carriage door an apparatus
consisting of a revolving disc containing movable rods which when not in motion
fall into the disc on the upper part but which when the disc is set in motion by a
band or cord connected with the axle of the carriage wheels fly out to their extreme
allowable length. Underneath the floor of the carriage and balanced by movable
weights or springs I place a bolt which passes through a hole in the floor and enters
a hole or tube in or attached to the lower part of the door when the train is in
motion, this bolt having curved plates attached which are acted upon by the
movable rods in the manner hereinafter described. When the carriage is in motion
the disc A. is set in motion by the band or cord connected with the axle of the
carriage wheels and going round the axle of the disc A. the movable rods fly out to
their extreme allowable length, the curved plates B. are released and the bolt C. to
which they are attached passes through the hole in the floor and enters the hole or
tube in or attached to the lower part of the door, effectually securing it. When the
carriage is brought to a standstill the movable rods D. fall into the disc A. on the
upper part pulling down the curved plates B attached to the bolt C. causing the bolt
to drop and thereby releasing the door which can then be opened in the ordinary
manner. Fig. 1 is a front view of the disc when revolving. Fig. 2 a front view
of the disc when stationary. Fig. 3 a side view of the disc when revolving.
Fig. 4 a side view of the disc when stationary. Fig. 5 when revolving. Fig. 6
when stationary. 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 :
»
1. The apparatus consisting of the revolving disc A. and movable rods D. in
combination with the curved plate B. and locking bolt C. substantially as and for
the purposes hereinbefore described.
2. The use of the said disc applied seperately to each door as in Figs. 3. and
Fig 4.
3. The use of the said disc applied to two opposite doors, the one disc operating
simultaneously on both doors as in Fig. 5. and Fig. 6.
