What we claim as our invention is:
.
1. A lamp having a casing provided with an
opening, a pair of laterally spaced light units in
said casing for projecting light rays through said
opening, and a common mounting for said units
including a pair of cooperating frames, one being
?xed in the opening in said casing, the second of
said frames being substantiallyv parallel to the
?rst mentioned frame and having dished annular
10
?anges embracing and forming seats for said
units, one of said dished ?anges being offset rela
tive to the other to hold the unit carried thereby
in a tilted position relative to the other unit, and permitting movement in unison of both of said
units as aforesaid.
an adjustable connection between the frames in
3. A lamp having a casing provided with an 15
dependent of the casing permitting the second
opening,'a
pair of laterally spaced light units in
frame and units carried thereby to be bodily
moved relative to the ?rst mentioned frame and said casing for projecting light rays through said
casing, the construction and arrangement of said opening, and a common mounting for said units
including a pair of cooperating frames, one being 20
units and annular ?anges being such as to pre
clude movement of said units relative to each ?xed to said casing, the second of said frames
other, while permitting movement in unison of being substantially parallel to the ?rst mentioned
frame and having dished ?anges embracing and
both of said units as aforesaid.
,
2. A lamp having a casing provided with an forming seats for said units, one of said dished
opening, a pair of laterally spaced light units in ?anges being o?'set relative to the other to hold 25
said casing, and a common mounting for said
, units including a
30
pair of cooperating frames,
one being mounted in the opening in said casing
and having a lateral ?ange, the second‘of said
‘frames being spaced from the lateral ?ange of
the ?rst mentioned frame, said second mentioned
frame having dished annular ?anges embracing
and forming seats for the respective units, one
85 of said dished ?anges being oifset relative to the
other so as to hold the unit carried thereby in a
tilted position relative to the other unit, and an
the unit carried thereby in a tilted position rela
tive to the other unit, and an adjustable connec
tion between said frames permitting the second
frame and units carried thereby to ‘be bodily
moved relative to the first mentioned frame and
casing, the construction and arrangement of said 30
units and dished ?anges being such as to preclude
movement of said units relative to each other,
while permitting movement in unison of both of
said units as aforesaid.
