HEADLIGHT FOR AUTOMOBILES
Henry J. Klein, Washington, D. C.
Application August 8, `1936, Serial No. 95,003
9 claims. (Cl. 24U-8.11)
’l’his invention relates to automobiles and has
special reference to headlights for automobiles.
One important object of the invention is to
provide an improved form of headlight so com
Oi bined with the front of the engine hood as to be
housed therein, it being understood that by the
front >of the hood is meant the grille or the
radiator, or both grille and radiator.
A second important object of the invention is
to provide an improved headlight construction
wherein a single reflector is positioned behind
' Fig. 5 is a fragmentary section on the line
In the embodiment of the invention as here
shown, it has been illustrated as applied to a well
known form of automobile having the front of 5
the hood IIJ constituted by a peculiarly shaped
grille or guard II behind which is a radiator I2.
While thus shown it will be obvious from what
follows that the invention may, by minor changes
in size, form and details, be equally well applied 10
to the fronts of other types _of automobile hoods
both right and left lamps so that it is impossible . whether such fronts are constituted by a grille or
for the reflector to throw the beam of light from
one lamp at a different angle to the horizontal ,
than the beam of light from the other lamp.
A third important object of the invention is to
provide a headlight of the above character hav
ing a pair of lamps adjacent each end of the re»1
flector.
20
`
A fourth important object of the invention is to
provide a novel dimming arrangement lfor such a
headlight whereby one lamp at each end of the
reflector may be shielded from front observation
for driving in certain localities such as city
streets, well lit roads and the like.
~
A fifth important object of the invention is
to provide a novel headlight construction whereby the operator may deflect the light from all
of the lamps downwardly when desired, as when
the radiator itself. »
`
.
In the hood Ifront is formed a transversely ex
tending elongated openingxIS behind which is 15 »
mounted a reflector I4. 'I’his reflector is so
constructed that its forward end is open and ,
conforms in general outline to the opening I3,
being thus elongated transversely of the hood.
Each side wall I5 of the reflector isof semi- 2n
paraboloidal form and the part I6 between these
side walls is parabolic in cross section, as clearly
shown lin Fig. 4. The focal points of all sec
tions of the part ~Iii and of the semi-paraboloidal
sides lie in the same straight and horizontal line. 25
`Mounted' in the rear of this reflector is a set of
four lamp sockets, there being two sockets I'I
axially alined with the axes of the semi-para
boloidal ends and two other sockets I8 having
meeting another automobile, the headlight thus - their -axés'in the horizontal focal plane of the 30

With the above and other objects in view, the
invention consists in general of -certain novel
details of construction and combinations of parts
hereinafter fully described, illustrated in the ac~
companying drawings and specifically claimed.
In the accompanying drawings like characters
of reference indicate like parts in the several
views, and:

width that it may span the distance between the 40
lampso'ckets I8. Fixed on the upper rear part
of the reflector is a pair of spaced brackets 24
wherein is journalled a rock shaft 25 having fixed
thereon a pair of sleeves 26 carrying forwardly 45
extending rock arms 21 and a pair of -rear
wardly extending rock arms 28. The forwardly
extending rock arms 2l have a bar 29 fixed to
their free ends and this bar lies on the flaps 22
and 23 adjacent theirfo-rward ends so that rock- 50
ing the shaft 25 in one direction will depress the
free ends of all three flaps simultaneously. The
arms 2B rest normally on the flap 22 adjacent its
hinge so that rocking the shaft 25 in the other
I direction will depress the flap 22 alone. These 55
