Wo EVELYN ROWE, of 3 Hawthorn Place, New Wortley, Leeds, School Master,
and JAMES SAMUEL SMITH, of Gledhow Street, Tong Road, New Wortley, Leeds,
Mechanic, do hereby declare the nature of this Invention to be as follows:-
The object of our invention is to indicate when railway carriage and other doors
are fastened or unfastened, whereby passengers and other persons may be cautioned
as to such doors being fastened or unfastened before leaning against or upon them.
According to our invention we attach to that support or part of the carriage
forming the side of the door-way into which the lock engages when the door is.
fastened, a casting which is partially hollow or fluted and arranged so that a vertical
slide (having the required indications upon it) and which is attached to a rod, can be
moved up and down the hollow or channel formed by the fluted part so as to give the
required indications to the passengers as to the door being fastened or unfastened.
On the said rod is a spiral spring fastened at its top end to such rod, and at its lower
end bearing against a projection or collar on the casting.
The lower end of the sail rod is formed after the manner of an' elbow which
passes into the support aforesaid and upon which the tongue, bolt or catch of the
carriage door acts.
The top part of the casting is preferably formed like a window so as to distinctly
shew the indications when the slide is moved, and the indicating slide is attached to
the top of the said rol.
The top of the slide has the word "Shut" upon it, and the bottom the word
"Open."

page_text: The action is as follows:-When the carriage door is closed the tongue, catch, bolt
or lever of the lock presses down upon the elbow, by this means the rod is also moved
and the slide along with it, thus indicating to the passengers that the door is fastened
by bringing the word "Shut" opposite the window.
When the door is unfastened the spring moves the rod back or upwards and brings
the word "Open" opposite the window thus indicating that the door is unfastened.
Our invention is applicable to other doors besides carriage doors, with slight
modifications.

We, EVELYN ROWE, of 3 Hawthorne Place, New Wortley, Leeds, School Master,
and JAMES SAMUEL SMITH, of Gledhow Street, Tong Road, New Wortley, Leeds,
Mechanic, 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 :—
The object of our invention is to indicate when railway carriage and other doors are
fastened or unfastened, whereby passengers and other persons may be cautioned as
to such doors being fastenied or unfastened before leaning against or upon them.
DESCRIPTION OF DRAWINGS.
Fig. 1, shows an elevation of our invention-indicating that the door is "shut" or
fastenod.
Fig. 2, shows an elevation of our invention-indicating that the door is "open" or
unfastened.
Fig. 3, is a sectional elevation of our invention applied to a railway carriage.
Figs. 4, 5 and 6 show modifications of elbow arrangement or means for operating
the indicating slide.
According to our invention we attach (within the carriage) that support A or
part of the carriage forming the side of the door-way into which the lock engages
when the door is fastened a casting B, which is partially hollow or fluted and arranged
so that a vertical slide C (having the required indications upon it, and which is
attached to a rod D) can be moved up and down the hollow or channel formed by the
fluted part, so as to give the required indications to the passengers as to the door
being fastened or unfastened.
On the said rod D is a spiral spring E fastened at its top end F to such rod, and at
its lower end bearing against a projection or collar H on the casting B.
The lower end K of the said rod D is formed after the manner of an elbow which
passes into the support A aforesaid and upon which the lever, bolt. or catch L of the
carriage door acts.
The top part M of the casting B is (preferably) formed like a window N so as to
distinctly show the indications when the indicating slide C is moved, and the indicating
slide C is attached to the top 0 of the said rod D.
In the top part of the window N is fixed a dial C, this dial is kept in position by
two prongs or supports, which act as guides for the indicating slide (when such is
moved up and down, and also keep the dial (in a fixed position.
The top part P of the indicating slide C has upon it the word "Shut" or its
equivalent, and the bottom part R has upon it the word "Open" or its equivalent.

page_text: The action is as follows:
When the carriage door is closed the tongue, catch, lever or bolt I of the lock
presses down upon the end S of the elbow, by this means the rod D is moved down-
wards and the indicating slide C along with it, thus indicating to the passengers that
the door is fastened by bringing the word "Shut" opposite the window.
When the door is unfastened the spring E moves the rod back or upwards and
brings the word "Open" opposite the window thus indicating that the door is
unfastened.
In figures 4 and 5, the rod D is operated or moved upwards by a lever D' working
on a pin D³, the bolt, lever or catch of the lock pressing down upon the end S, and
thus imparting the necessary motion when the door is fastened, the spring E having a
contrary action returns the lever D₁ to its horizontal position when the door is
unfastened.
In figure 6, an incline T, attached to or forming part of the lever U, operates or
moves upwards the rod D, when the tongue or bolt of the lock pushes against the
end S of the said lever, such lever working on a pin or pivot V. The end S being so
arranged as to entirely fill the cavity or recess in the striking plate.
In these modifications the action of the spiral spring E is contrary to that shown
and described in Figs. 1, 2 and 3. Such spring in Figs. 1, 2 and 3 being fastened at
its top end F to the rod D and bearing against a projection or collar H at its lower
end on the casting B. Whereas in Figs. 4, 5 and 6, the said spring is fastened at its
lower end F in the same manner, and bears against the projection or collar H at its
top end.
The principle of our invention is applicable to other carriage doors besides railway
carriages.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :-
1. Automatically indicating within railway and other carriages when the doors are
fastened or unfastened, for the purpose setforth.
2. The combination of the indicating slide C, spring E and rod D, operated by the
door catch L substantially as shown and described.
1+
3. The general arrangement of indicating apparatus substantially as and for the
purposes shown and described.
