ADJUSTABLE SPOTLIGHT Filed Dec. 29, 1947 2 Sheets-Sheet 1 E INVENTOR.

Louis 0. PHILLIPS ATTORNEY Jan. 23, 1951 D. PHILLIPS ADJUSTABLE SPOTLIGHT 2 Sheets-Sheet 2 Filed Dec. 29, 1947 INVENTOR. Lou/s Q FHILLI P5 ATTORNE Patented Jan. 23, 1951 UNITED STAT ES TENT OFFICE This invention relates to electrical lighting fixtures usually supported from the ceiling.

The main object of this invention is to provide an electrical lighting fixture with means so that the light may be directed to any object in the vicinity by simply manipulating a device in the face of the fixture.

A further object of this invention to enable a light reflector in a hanging fixture to be rotated almost a complete circle and to be raised or lowered vertically so as to throw the light beam to any desired angle up to l degrees.

Other novel features of the invention will appear from the following description when read in connection with the accompanying drawings:

In the drawings:

Fig. 1 is a section of the fixture taken on line l-l Fig. 2.

Fig. 2 is a bottom view of the fixture.

Fig. 3 is a section taken on 3--3 Fig. 5.

Fig. 4 is a section taken on ei Fig. 2.

Fig. 5 is a section taken on lin Ei-5 Fig. l.

Fig. 6 is a section showing the hinge device.

Fig. '7 is a perspective View of the tilting device.

Referring to the drawings, the invention is shown within the housing 16, fastened to a face plate II and collar 12 by means of screws i3, as shown. Adjacent to the collar i2, there is provided a ring I4, with a projecting flange 15 resting on the collar 12. To prevent the ring it from being out of alignment a plurality of angular shaped supports it are fastened to the collar l2 and projecting over the flange !5, but allowing the ring 14 to rotate freely between the supports 16 and. the collar l2. One of the angular shaped supports has a longer projecting arm 11, which acts as a stop when hit against the upstanding finger is, fastened to the ring Ii. This arrangement allows the ring to rotate almost a complete circle, that is except for the width of stop if.

Within the ring 14, there is set a reflector [9, housing an ordinary incandescent light 20, with electric wires 2| arranged loosely.

The method of raising or lowering the reflector l9, and thereby the beam of light is as follows: The reflector 19 is hinged to th ring 54 by the hinge 22, the lower part of the hinge 23 being fastened to the ring is, and the upper part of the hinge 24 is then turned away almost 90 degrees and bifurcated, the edges 25 are then turned back thus forming a support 26 for the block 21 and its projecting pins 21'. The block 21 is threaded to receive a screw 28 passing through an apertur 29 in the ring I4. A knob 30 forms the end of the screw 28. t

It will be noted that as the knob 30 is turne it will bring the block 21 nearer or further, and thus move the reflector I9 up or down as the case may be.

In the upper part of the housing 13 there is a metal bowl 3! suspended from the housing 16 by a screw 32 and nut 33, the bowl 3! is loosely fitting and movable within the housing it. A plurality of holes 34, which operate as vents, coact with openings 35 in the top of the housing E0. The space 35 between the bowl 3! and the housing [9 is used for locating continuous wires when a series of fixtures are used, but not shown.

The wire 21 is usually held slack so as to allow for movement of the reflector iii. The wire enters the housing it] through a slot 3?, and then into the bowl 3| through a grommet When the fixture is to be used in connection with other fixtures, angle plates and ii are provided with apertures 52 and :3 for bolting or connecting to the adjacent fixtures.

When the fixture is to be used by itself, a special hanging extension is is provided which is fastened to the ceiling E5 and to the crossbar 56, attached to the housing If by means of bolts and nuts 4'1 and 48. The extension G l holds the crossbar 46 by means of a locknut it and washer 5%.

It will be obvious that the invention is not limited to the specific forms described and illustrated in the drawing, but is capable of a variety of mechanical embodiments. Various changes, which will now appear to those skilled in the art, may be made in the form, details of construction, and arrangements of parts without departing from the spirit of the invention. Reference is therefore to be had to the appended claim for a definition of the limits of the invention.

I claim:

In a fixture of the class described, a support for a reflector, means for tilting said reflector, comprising a hinge with upper and lower parts, the lower part being connected to said support, the upper part being connected to said reflector, said upper part being bifurcated and the ends turned to form a bearing for a block and projecting pins, said block being threaded to receive a screw which pierces said support and termimates in a nut, said nut bearing against said support and when turned tilting said reflector on the hinge.
