5 Claims. (Cl. 240—41.35)
This invention relates to an improvement in
head lights for automobiles,and consists of an im
proved construction, arrangement and combina
- tion of parts hereinafter described and ‘claimed.
The primary object of my invention is to pro
vide a construction for automobile head lights, in
which three sources of lights are provided, one
being especially for throwing a concentrated light
Figure 13 is a perpendicular view of the conical
shaped re?ector looking downwardly uponv the
same.
Referring now to the drawings in which vari

over a short distance is desired. The "construc
It is an elongated housing preferably of circular
cross section and having a lens II at its forward
end secured to the housing by a retaining ring I2
above a predetermined level.
-
.
-
A further object'of my'invention is to provide
novel means for adjusting the level in which the
‘rays of light will be projected.
-'
A still further object is to provide a-construc
tion in which a housing‘ is employed for the
lighting structure and such structure is made as
a self-contained-unit, removable from the hous
ing for adjustment, repairs, or other ‘purposes.
The means by which the foregoing and other
objects are accomplished, and the manner of their
accomplishment, will readily be understood from
the following description on reference to the ac
companying drawings, in which:--
‘
Figure '-1 is a sectional elevation ‘showing the
‘Figure 2 is‘ a front elevation {of the device wit
the lens attached thereto;

Figure 3 is a complete unit for raising and
lowering the rear end of the head light assembly;

5-5 of Figure 2;

Figure 6 is a complete section taken longitu
dinally through the forward reflector and rear
counter-re?ector with the upper portion ‘that-con
nects the two re?ectors;
'7 Figure 7 is a View of the counter-re?ector at
the rear end of the device illustrated in Figure 6;
Figure 8 is a front elevation of Figure 6;
>
Figure 9 is a longitudinal sectional view ofa
device similar to that shown in Figure '1, with'the
exception it can be used either with or without a
reflector;
Figure 10 is a front elevation of head lighting
device with the lens removed;
of the usual and well-known type.
Disposed within the housing I0 and accessible
on removal of the lens H is a unitary structure
including a diaphragm 13, having an opening ISA,
the major portion of which opening lies below the
longitudinal center line of the housing. Behind
this diaphragm is a casing 9 having a wall 14 at
its rear end, said wall I4 preferably being of gen
eral parabolic shape, and being centered on the
longitudinal axis of the housing. The cylindrical
walls ll‘) of the casing extend forwardly at a
downward incline to the opening [3A in the dia
phragm l3, the lower half of the walls l5 being of
a circular shape, and the upper portion 15A being
?attened and downwardly directed and extending
forwardly to said opening I3A at a level prefer
ably very slightly above the longitudinal axis of
the casing Ill. The lower half of the walls of the
casing terminates at the diaphragm I3, and ‘the
entire casing is secured to the diaphragm as by
brazing, welding, or in any other manner desired.
22)
A re?ector I6 is mounted on the inside of the ,
preferred embodiment of ‘my device;
a
removed;
ous parts are indicated by numbers and ?gures, _,
‘tion vof the head lights provides means for mask~
ing and directing the light from its source in
I ‘such a manner that at least the major portion if
not all of the light is directed along the road
surface to be lighted, and substantially all the
glare from such lights is prevented from rising

Figure 12 is a front view of Figure 11 with lens

10 tional purposes, and the other one being primarily

'
casing 9 and is pitched slightly forward so that ‘
its center beam comes slightly below the center
or horizontal edge 30 of the inside assembly illus
trated in Figure 6. Mounted in re?ector l6'is a
light-bulb IT, to which a suitable current wire l8
leads from a source of current, the light I? being
mounted in the ‘usual socket I9‘. The upper ,por
tion of the diaphragm I3 is countersunk horizon
tally to form a round and oblong shaped re?ector
20 in which is set a socket 21. Into this socket ?ts
a bulb 22 used for directional purposes, and cur
rent is supplied by a wire 23 leading to the source
of current. The numeral .24 designates a combi
nation concave and oblong shaped re?ector at
the center of which is formed a socket 25 to re
ceive a bulb 26, current being supplied by a wire 50
21 leading to the source of current. Mounted on
the inside of casing 9 is a semicircular counter
re?ector 28 connected with the reflector 24 by a
plate or bridging wall 29, the two re?ectors and
‘the bridging wall being preferably made as a vunit
2
2,122,413
cut from a single piece of material. The upper
end of the counterre?ector and the rear end of
the wall 29 intersect to form an edge 39 extend
ing transversely through the casing 9 from one
side thereof to the other. When viewed from its
front end, the wall 29 is in the form of a lower
segment of a circle, as shown at 3|. The upper
face of this bridging wall is of a dull or non
re?ecting color so that light will not be re?ected
10 upwardly therefrom. A supporting bolt or cross
of an approaching car. The upper portion of
re?ector I6 is masked and at the same time the
lower portion of the re?ector I6 is masked by
the counterre?ector up to center or horizontal
edge 30, thereby effectively cutting on" those rays
which might be re?ected from the lower portion
of the re?ector [6. The rear wall i4, shown in 10
Figures 1 and 9, may be used as a re?ector should
under the rear end of the bridging wall and at
the center of its rear edge t0 the counterre?ector
however, to use the re?ector such as the re?ector
ceive bolts 49 for securing the same to brackets
49A mounted at sides of the front end of the
casing.
Now referring to unit for raising and lowering
the rear end of head light assembly, 34 and 34A
are nuts through which a bolt 35 passes. This
bolt is threaded at one end and has a ?anged or
39
ISA of the tubular member l5- prevents any direct
rays from rising high enough to blind the driver
rod 33 extends transversely through the casing
carries a tongue or tip 152 which engages in a slot
15 43. The front plate in which the re?ector 24 is
formed has openings 48 near its margins to re
2.5
cerned, the forward edge of the upper portion
the re?ector ‘l6 be removed.
It is preferable,
16 in preference to the re?ector I4.
, In the form shown in detail in Figure 11, the 15
rear end of the casing is formed with a wall 61
which will serve as a re?ecting means in the
event that the re?ector I6 shown in Figure 11
is removed.
