PROVISIONAL SPECIFICATION.
Improved Apparatus for Placing Fog Signals upon the Railway
Lines.
I WILLIAM FRANCIS STEVENS of 30 Ellora Road Streatham in the County of
Surroy Plumber do hereby declare the nature of this invention to be follows:-
:-
A apparatus made of iron brass or other hard metal of a circular shape to hold
fog Signals A. A slide B works under in such a manner that when the lever C which
is attached to slide B is pulled from signal box it pushes fog signal A which drops
into groove D on to railway metal E and is kept there by stop F which is worked by
a spring G on other side of metal E until the train passes when slide B is put back
another fog signal A drops into groove D ready for use when required. The reserved
fog Signals A are kept in their place by two spring clips H so that only one fog
signal A can be pushed out at a time. Door J is to refill apparatus.

Improved Apparatus for Placing Fog Signals upon the Railway
Lines.
I, WILLIAM FRANCIS STEVENS of 30 Ellora Road Streatham in the County of
Surrey Plumber 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, reference being also had to the accompanying drawings and
-leiters thereon:
This apparatus is made of iron brass or other hard metal and consist-of-a-box-of-a-
circular shape in which detonators or fog signals are placed the box is fixed on to a
flat platform raised to the level of and parallel with the line in which the detonators
is to be placed as hereinafter shewn. On the platform or bed is a groove running
from end to end and directly-under-the-circular box before mentioned in the groove
is a slide divided into two parts and connected together by a hinge in the end of the
slide there is a circular hole of the same size as the box. At the back of the slide is
a lever by which the slide wherein the circular hole is situated is drawn back directly
under the bottom of the box when the lower detonator drops into the hole in slide
when it becomes necessary to place the detonator on the line the slide is pushed
forward by means of the lever, untill that part of the slide containing the detonator
is on the line. On the platform under the slide containing detonator is a crank
from which there is a lever rod running on a pivot under and tapering to a point on
the inside of line on the approach of Locomotive the flange of wheel passes between
the line and the lever point forcing up by means of the crank that portion of slide in
which the detonator is placed and leaving the detonator on the line to be exploded
by the wheel passing over it there is a small flat spring under the slide whereby that
portion of the slide containing the circular hole when raised is prevented from falling.
After the Locomotive has passed the slide is drawn back by means of the lever that
part of slide which is raised falling back into its place clear of the line and is drawn
back until the hole is again under the box. When a detonator is admitted, there
are two spring clips fixed upon the platform which are worked by means of a stop on
slide, and when the circular hole containing the detonator is under the circular box
the clips are forced between the slide containing the detonator (see dotted lines in
Fig. 1) and the detonators that are above within the box thus supporting the weight
from the detonator within the slide so as not to impede the action of the slide, if
after the detonator has been placed on the line as describe above it is found it is not
required it can be drawn into the box under the other detonators by means of the
lever on the end of slide.
Letter P on
(Fig. 1 & 2) is the circular box containing the detonators. J is the
door in box in (Fig. 1) whereby the same is refilled with detonators when required
R is the platform on (Fig. 2) whereon the apparatus is placed. D is the groove in the
platform on (Fig. 2). B is the slide in the groove in (Fig. 1 & 2) B. b is that part
of the slide containing the circular hole in (Fig. 1 & 2)° C is the lever attached to

page_text: the bottom of slide in (Fig. 1) E is the line on which the detonator is placed in
(Fig. 1 & 2) H is the clips on (Fig. 1 & 2) K is the lever rod running under
the line in (Fig. 1 & 2). L is hinge connecting slide B. with slide B in Fig. 1 & 2
M is pivot under line in (Fig. 1 & 2) whereon the lever K works N is the flat spring
under slide in (Fig. 1 & 2) which supports that part of slide B b when raised as
in (Fig. 2) S is the crank attached to Lever K under slide B b on (Fig. 1 & 2)
Tis the stop on slide B in (Fig. 1 & 2) Z is a stop fixed on platform as a guide B
see (Fig. 1 & 2) A are the detonators (Fig. 1 & 2).
Having now particularly decribed the nature and general construction of my
Invention and in what manner the same is to be performed, and having dispensed
with those parts marked F. G and I in original drawings & specifications I declare
that what I claim
