l illotlllel' object of the invention relates to o the provision of means for adjusting the "lamps within their casing for directing the fiood'light upon a particular objectsuch as a sign or building, for example. 1

Other objects relate to various ieatures of construction and arrangement of parts which will be apparent from a consideration of the following specification and accompanying drawings, wherein:

li iel 1-is a broken side elevation of a. lamp casing illustrating the lamp mounting means which constitutes one embodiment of the present invention; 7

Fig. 2 is an enlarged side elevation of the lamp mounting and related structure;

Fig.3 is a transverse sectional view taken on the line 3 8 of Fig. 2; a f

in the drawings 10 indicates generally a lamp casing which may be of any suitable construction and if desired arranged for mounting on a post "11. The casing comprises a base 12 extending diametrically across the interior of which is a bracket 13 in i the form of a bar having a depressedor ofl'- set portion 14. The portion M has an elon- L5 gated opening 15 therein through which ex-- tends the rod or standard 16 which also passes through the hub-like socketed exten sion 17 of the bar 18 which is adjustable longitudin ally of the bracket 13 by means of the slots 19 through which the screws 20 pass. Thus if it is desired to adjust the standard 16, the screws 20 can be loosed and the standard 16 moved laterally a distance equal to the length of the slot 15. A fastening device,

' such as the set screw 21, is provided. for se-' curing the standard 16 at the desired elevation.

Secured to the standard 16 is an arm 22 provided with an enlarged flat portion 23 which is arranged to be clamped by a wing nut 24 1929. Serial No. 379,138.

operating on a bolt 25 to a somewhat similar portion 26 projecting from the curved cruciiorm supporting frame indicated generally by the numeral 27. The arms 28, 29 and 30 of frame 2? preferably are provided at their 5;;

free ends with hooks 31 forming supports for the reflector 32 which 18 held in position by a clip 83 secured to the fourth arm 34 oithe member 27. Resilient pads 35 of felt or the like cushlon'the reflector 32, which may be of glass, agamst breakage by vibration caused by heavy trucks, street cars, or the like. i The arm 8% extends upwardly and forwardly illustrated to form a support. 36 for the screw socket or receptacle 37 which receives-the lamp 38 which is thereby held in proper position with respect to the focus of the reflector.

By means of the mounting described, itwill be apparent that the reflector 32-andlamp 381" canibe adjusted universally to throwthelight upon the desired object," that is, they con be adjusted on a horizontal axis by means of the nut 24: and bolt 25 and on a verticalaxis and raised or lowered by loosening the set screw 21.- Where it is desired to throw the light downwardly at a sharp angle the screws 20 can be loosened and the plate 18'can be moved laterally. of the supporting bracket 13 to permit the lamp and reflector to be. given the necessary inclinationl To remove the objectionable shadow which would appear on the lamp casing at the side shielded-by the reflector, a second lamp 39 is utilized. This. lamp may be of less wattage,-'.

if desired, than the lamp 3,8, as its purpose is to provide limited street illumination and 'to remove the above mentioned shadow caused bythe reflector and'its supporting means.

The lamp 39 is carried'in a conventional socket d0 which is secured to the clip 41 which in turn is attached to the arm 34. The lamps are thus movedin 'uniso'n'when the reflector is adjusted, the'lamp 39always being in position witlrrespect to the lamp 38 to eliminate the shadow at the rear of the reflector;

lhe conductors (not shown) pass upwardly through thehollow base of the casing. and through eyes 42' carried by the arms 28, 29 and thence to the sockets of the lamps- Although I have shown and described one embodiment of the invention for the purpose of illustration, I do not wish to be restricted specifically thereto except as so limited by the appended claims.

What I claim is:

l. The combination with a lamp casing, of a transverse support therein, said support having a slotted intermediate portion off-set from the upper plane of the support, a slidable member secured to said support and being adjustable longitudinally thereof, said member having a standard engaging means, a standard engaged by said means with its lower end adapted to extend through said slot to permit the lateral adjustment of the standard with said slidable member, and a reflector and lamp supporting frame carried by said standard.

2. The combination with a lamp casing, of a transverse support therein, said support having a slotted intermediate portion offset from the upper plane of the support, a slidable member secured to said support and being adjustable longitudinally thereof, said memher having a standard engaging means, a standard engaged by said means with its lower end adapted to extend through said slot to permit the lateral adj us ment of the standard with said slida le member, and a redoctor and lamp supporting frame carried by said standard, said standard and frame having cooperating elements permitting the adjustment of said frame on a horizontal axis.

3. YA lamp mounting comprising a frame, a reflector carried thereby, a cylindrical standard supporting said frame, a transverse support having an intermediate slotted portion, a member secured to said support and bein adjustable lomz itu inaliy thereof, said member having a cylindrical socket for slidably and rotatably receiving said standard, said socket being alined vertically with said slot and through which said standard is adapted to extend to permit of vertical adjustment thereof, said socket having a locking device for securing said standard in adjusted position within said socket.

4. Apparatus of the class described comprising a support, a member adjustable longitudinally thereof, a cylindrical standard carried by said adjust-able member, said member having a releasable locking device to permit of the rotative and vertical adjustment of said standard relatively to said support, a frame horizontally pivoted to said standard, said frame comprising a plurality of curved arms provided with reflector engaging mem bers, a reflector carried thereby, a lamp socket secured to one of said arms, and a lamp supported in said socket in position with respect to said reflector, said lamp and reflector maintaining their relative positions in all positions of adjustment of said frame.

5. In combination, a lamp casing, a standard therein, a frame pivotally supported by said standard for movement on a horizontal axis, a lamp and a reflector therefor supported by said frame, and a second lamp carried by said frame at the rear of said reflector and movable therewith for obliterating the shadow of said reflector and frame.

6. A lamp mounting appara us comprising a frame having a plurality of arms, a reflector carried by said arms, one of said arms being provided with a lamp socket for supporting a lamp in position before said reflector, a bracket secured to said frame at the rear of said reflector, and a lamp socket carried by said bracket.

7. In combination, an enclosure for a light source. an independent unitary assembly adapted for disposal within said enclosure, said assembly including a reflector, a floodlighting lamp supported adjacent one edge of said reflector and in fixed focal relation with respect to the reflecting surface thereof, and a street-lighting lamp arranged in fixed relation with respect to the rear surface of said reflector, and. a supporting member for said assembly arranged for quick-detachable securement adjacent one edge of said enclosure, said supporting member being angularly shiftable about an axis substantially coincident with that of said enclosure.

8. In combination, a glass globe, a unitary assembly including a reflector and a pair of lamps respectively arranged at opposite surfaces of said reflector, the light rays emanating from one of said lamps being reflected by said reflector for flood-lighting purposes, the other lamp serving as a street-lighting source of light and to dissipate the shadow effects caused by said reflector, means for supporting said assembly, said means permitting angular shifting of said assembly as a unit about an axis substantially coincident with that of said globe, and additional. means for permitting angular adjustment of said assembly about an axis extending transversely of said globe.

In testimony whereof, I have subscribed my name.

OLIVER M. KING.
