1 Claim.
This invention relates to combined signal de
(Cl. 177-329) '
vices and flash lights and has for an object to
provide an improved portable lamp of this char
acter particularly adapted to the utilization of
tubes containing a gas such as neon in which an
electrical discharge causes luminescence.
A further object of the invention is to provide
a compact device of this character which will be
selectively operable to display a neon danger signal such as danger ol' stop, or to be used as an
ordinary ñash light.
A further object is to provide a device of this
character which will be formed of a few strong
simple and durable parts, which will be inex
pensive to manufacture and which will not easily
get out of order..
With the _above and other yobjects in view the
invention consists of certain novel details of con-~
struction and combinations of parts hereinafterv
fully described and claimed, it being understood
that various modiñcations may be resorted to
within‘thelscope o1' the appended claim Without
opening I5 to receive a reflector I6 and a. lens I1
for housing a ilash light bulb I8. A retaining
ring I9 removably secures the lens in place to
permit replacement of a burned out bulb. Oppo
sitely disposed pins 20 are secured to the top of 5
the casing and have restricted necks to work in
bayonet slots 2| formed in the ring to remov
ably secure the ring in place.
A substantially U-shaped plate 22 of insulating
material is secured to the back of the casing by 1°
means of screws 23, as best shown in Figure 2.
A conductor bar 24 is secured to the inner face
of one leg of the plate and a conductor bar 25
is secured to the inner face of the other leg of
the plate. Leaf springs 2s and 21 named by the 15
bars removably secure a’ battery cell 28 in the
casing and electrically connect the poles thereof
to the bars 24 and 25. Similar springs 29 and 30
removably secure a battery cell 3| in the casing
above the battery cell 28. . '
A transformer 32 is secured to the legs of the
plate 22 above the battery cells', and is equipped
departing from the spirit or sacrificing any of . with a vibrator 33 to alternately make and break
the advantages of the invention.
In the accompanying drawing forming part of
this speciñcation,
Figure 1 is a longitudinal sectional View through
a combined signal and ñash light constructed in
accordance with the invention.
Figure 2 is a cross sectional view taken on the
line 2-2 of Figure 1.
Figure 3 is a longitudinal sectional view through
the device with parts in end elevation.
Figure 4 is a detail elld elevation showing the
means for applying and removing the flash light
lens to replace a burned out bulb.
Figure 5 is a fragmentary end elevation show
ing the switch for selectively controlling the dan
ger signal light or the flash light.
Figure 6 is a diagrammatic view showing the
electrical connections of the device.
Figure '7 is a diagrammatic view' showing'a
modified form of electrical connections.
Referring now to the drawing in which like
y characters of reference designate similar parts
in the various views, ill designates a casing hav
ing the bottom closed by a cap Il, one edge of
which is provided with a recess I2, as best shown
in Figure 3, tol receive a projection I3 on the cas
ing, thus forming a hinge upon which the cap
may be swung open against the pressure of a.
spring pressed pin I4 disposed in the casing di
ametrically opposite the projection I3. The top
of the casing is flared at the sides, as also best
shown in Figure 3, and is provided with an
the primary of the coil whereby high tension
alternating current is induced in the secondary 25
winding of the coil.
A step up transformer 34 is secured to the legs
of the plate 22 in superposed relation to the
transformer 32 directly inrear of a shield 35
Which is substantially U-shape in cross section, 30
as best shown in Figure 3. The shield is dis
posed in rear of an opening 36, as best shown in
Figure 2, formed in the front wall of the casing
near the top thereof. A transparent pane 31
closes the opening and is held in position in a 35
rabbet 38 in the casing by pressure of the shield.A`
It will be observed that the shield is formed of
spring metal and that the legs are terminally
directed in a reverse direction to form a channel
'which receives the sides of an oblong frame 39 40
whereby the shield is confined snugly in place
and in turn holds the pane 31 in place.
As shown in Figures 3 and 5 a substantially U--shaped switch arm 40 is pivoted on a pivot pin 4I
secured to one of the legs of the U-shaped plate 45
22, one end of the- switch arm being directed out
wardly to form a grip 42 which passes through
an opening 43 for rocking the switch to either of
its two closed positions or to neutral position.
Switch contacts 43' and 44 are disposed on-op- 50
posite sides of the switch arm and are selectively
engageable by the switch arm to close the circuit
to the flash light or to the neon light about to
be described.
A neon light 45 is disposed within the enclosure 55
tension alternating current as indicated diagram
of the shield 35 and may be secured to the pane
by glass lugs 46 or may be otherwise secured in
position. The neon light is of such form as to
constitute a signal word such as “stop” or
The electrical connections of the device are
best shown in Figure 6 in which it will be seen
that conductor wires 41 and 48 connect the ter
minals of the flash light I8 with the battery cells
10 and with the switch contact 43 respectively. The
primary winding of the transformer 32 is con
nected by conductor wires 48 and 50 to `the
battery cells and to the switch arm 40 respec
tively. The secondary winding of the trans
15 former 32 is connected by conductor Wires 5|, and
52 to the primary winding of the transformer 34.
'I‘he secondary winding of the transformer 34 is
connected by conductor wires 53 and 54 to the
matically in Figure 7. The rest of the electrical
connections for supplying the flash light 58 with
current are the same as previously described.
From the above description it is thought that
the construction and operation of the invention
will be fully understood without further explana
What is claimed is:
In a. portable flashlight unit, a casing of sub~ 10
stantially rectangular cross section providing a
wide front wall to display a warning signal, a sub
stantially U-shaped plate in the casing remova
bly secured to the rear wall of the casing and
having parallel legs extending along the ends of 15
tension alternating current from the transformer
the casing toward the front wall of the casing,
a battery in the casing carried by said legs. a
transformer secured to said legs above the bat
tery, a make and break device for the trans
former, a window pane in the front wall of the 20
34 will create luminescence in the neon gas in
the well known manner when the switch arm 40
is moved to engage the switch contact 44.
In some instances it may be desirable to dis
light in the casing between thßqnane and the
reflector, circuit wires connecting the trans
former to the neon light, circuit wires connecting
pense with the step up transformer 34 and to
employ merely a single transformer 55 similar to
the transformer 32 in connection with battery
cells 56 for supplying the neon light 51 with high
the battery to the transformer, and a switch on
the casing controlling the flow of current to the
last named circuit wires.

casing, a reflector in rear of said pane, a neon
