is to be thrown up into a position 14 for
permitting the doors and lenses 15 and 16
to be .opened.
The shade should be of such a design that
S5.when thrown down into al position 17 the
.upper portion 18 of the beam of lightvill
not strike the ,eyes'of the engineer or fire-
man in the scab of the approaching loco-
motive, and yet so that the track will be well
10 illuminated for some distance in front of the
locomotive on which the headlight shade is
being controlled.
The rod.11 may be provided with a grip.
ping portion 19 for permitting it to be easily
15 manipulated, and any suitable means, such
as a thumb-screw 20 may be provided tolock
the rod in anydesired position with respect
to the frame work 21 of the locomotive.
. It is seen that the shade of my invention
20 may be so designed and constructed that it
may completely cut off that portion of the
beam of light which would otherwise inter-.
fere with the vision of an approaching en-
gineer or fireman, but so that it will not cut
25 off that portion of the beam of light neces-
sary to illuminate the track immediately in
front of the locomotive carrying the shaded
headlight. In general the under portion of
the shade should be of reflective material so
30 as to throw the light down on the track to'
aid in illuminating the same.
Although I have shown and described a
shade which in normal position extends only
half-way down by the side of the lenses, still
35. I.do not limit myself to such a shade, inas-
much as it is evident that in some locations
it may be desirable to have a deeper shade,
while in other locations it mnay not be neces-
sary that the shade should extend half-way
40- down.
Although I have shown and described a
rod for connection to a point on the shade
for controlling the same from the cab, still
I do not limit myself to the use .of a rod,. as
45 it is evident that any suitable connector may
be, used. Neither do I limit myself to the
use of a thumb-screw for connecting the rod
to the shade, as it is evident that the na-
ture of this connector will depend upon
50 whether it is necessary to easily disconnect
the rod from the shade, and other circum-.
stances. Neither do I limit myself to the
use of lugs formed on the body portion of
the headlight and eais formed on the shade
55 and adapted to coperate with the lugs for
supporting the, shade; as the manner of con-
necting the shade to the body portion of
the headlight will depend upon.the size of
the 'shade, its shape, the shape of the head-
60 light and other circumstances.
It is evident that any suitable means may
be' provided 'in the .cab for controlling the
position of the shade, and this may be in theform of a thumb-screw as shown and de-
scribed, or. in the form of a rack or any other 65
suitable device.
Although I have shown and described a
shade adapted to be controlled from a dis-
tance by means of a rod or otherwise, still
I contemplate also the use of a. shade pro- 70
vided with a thumb-screw or other locking
device, so that it may be firmly secured in
any position without the possibility of being
controlled from a distance, as it is evident
that this would be the simplest form in 75
which my shade and attaching means could
be made.
I claim:-
1. In combination with the forward por-
tion and' lens of a headlight,, a swinging 80
shade therefor in the form of an apron sub-
stantially straight in its longitudinal direc-
tion and provided with downwardly hang-
ing side walls of substantial depth, the
shade being pivoted to the upper portion 85
of the headlight body rearwardly of the
lens, and being of such a width that the
downwardly hanging side walls extend out-
wa'rdly beyond the sides of the body of the
headlight to permit the shade to be swung 90
downward an amount to partially cut off
the main beam of light, and the side walls,
embracing the body portion to prevent the
escape of light sidewise past the shade,
whereby that portion of the beam of light 95
which is directed horizontally. down the
track is cut off and that portion thereof
which illuminates the track immediately
in advance of the locomotive is not cut off,
substantially as described. . 100
2. In combination with the forward por-
tion and lens of a headlight, a swinging
shade therefor in the form of an apron sub-
stantially straight in its longitudinal direc-
tion, provided with downwardly hanging 105
side walls of substantial depth, and of a
relatively reflective character on its lower
inner face, the shade being pivoted to the
upper portion of the headlight body rear-
wardly of the lens, and being of such a 110
width that the downwardly hanging side
walls extend outwardly past the sides of the
headlight to permit the shade to be swung
downward an amount to partially cut off the
main beam of light, and the side walls ein- 115
bracing the body portion to prevent the es-
cape of light sidewise past the shade, where-
by that portion of the beam of light which
is directed horizontally down the track is
cut off and is deflected downwardly to illu- 120
niinate the track immediately in advance of
the locomotive, substantially as described.
