7 Claims.

This invention relates in general to a floodlight unit, and more particularly to a floodlight units are mounted under water, it is extremely 'difiicult to relamp the same.

At the present time, there are two arrangements used for floodlights of this character. One arrangement is known as the wet niche installation in which the walls of the swimming pool are formed with niches into which a water tight lighting unit is arranged. This unit is provided with along waterproof cord, and the arrangement is such that the unit may be bodily removed from the niche and taken to the surface, whereupon it may be disassembled to the extent necessary to permit replacement of the lamp. This arrangement is not satisfactory, inasmuch as it requires a well experienced swimmer to stay under water long enough to remove the unit and again replace it after it has been relamped.

In the second arrangement, or dry niche installation, the walls of the pool are formed with suitable openings closed by a lens mounted in water-tight relation in" the face side of each opening. A sizeable trench, or series of manholes, are formed along each wall of the pool, and a lighting unit is mounted upon suitable brackets in this trench, or in the manholes, and. each lighting unit is arranged in register with an opening in the wall. The trenches, or manholes, are of sufficient dimensions to permit a workman to relamp the units without removing them to the surface. This arrangement results in a very expensive installation because of the necessity of considerable additional excavation and the additional amount of concrete work involved.

There are other types of installations wherein the floodlight, or fioodlight unit, is practically inaccessible. For example, on the ledges or parapets of ofiice buildings and other building structures.

My invention has as an object a fioodlight unit embodying a particularly simple and economical structure by which the unit may be quickly and conveniently relamped by a workman positioned a considerable number of feet from the unit.

The invention has as a further object a floodlight unit embodying a structure, as above referred to, including the provision of means whereby the reflector of the unit may be adjusted as desired through a remote control mechanism of particularly simple and economical construction.

The invention consists in the novel features and inthe combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a vertical sectional view of alighting unit embodying my invention with the reflector and other parts shown in elevation.

I Figure 2 is a rear elevational View of the floodlight casing with a portion thereof broken away to show the reflector mounting.

Figure 3 is a vertical sectional view of the upper portion of the casing and contiguous parts of the lamp receptacle assembly taken at substantially right angles to the sectional view in Figure '1, as indicated by line 3-3, Figure 5.

Figure 4 is a fragmentary sectional View of the upper portion of the lamp receptacle assembly taken on line 44, Figure 5, and including the lower portion of the lamp receptacle assembly shown in elevation;

Figure 5 is a transverse sectional view taken on substantially line 5-5, Figure 1.

The invention comprises generally a casing which may be of any suitable size or form and which is provided with an aperture in one-side. A tubular member is arranged in this aperture and extends outwardly. If desired, a reflector may be mounted within the casing.

The unit further includes a lamp receptacle assembly including a lamp mounted in the receptacle, and which assembly is manually insertable through the tubular member, and means is provided for accurately positioning the lamp in the focal axis of the unit.

In the embodiment of the invention here shown, the casing consists of a rear bowl-like portion l0 and a forward cylindrical section I I, the two sections being formed with complemental flanges l 2 which are secured together as by screws I3. A suitable lens I4 is secured in the outer end of the cylindrical section II to form a water-tight closure for the casing.

The casing is formed with an aperture 21 arranged -in one side thereof and with a smaller threaded aperture to receive a drain pipe 22 to permit the escape of any moisture that may collect within the casing. A sleeve 23 is mounted in f the aperture 2| as by cap screws 24. Preferably,

bular member 28 is of sufiicient length to extend within a short distance of the top surface $1} on 1 the wall of the pool. Preferably, the upper end of the tube 28 terminates in anaperture formeg in a housing 3| which is supplied with an electrical receptacle 32. For a swimming pool installation, it will be understood that the .entire casing is arranged in the concrete wall 313, asjs also the tubular member 28 and the upper housin .31.. T is installatio 'is mad y se uring th casin n th f m fo the side w ll of th pe l, inserting the tubular member '28 int-he sleeve 23, and mounting the housing 3! in the form forthe t p portion of the wal ft r, the spa etween th perture 2 and th sle v 273., and the space between the upper end of the tube 28 and the ape ture and o s n are l ed v i suitable caulking material, as at 3?. Thereafter, th con r t s pou ed a d t es Por ion o e unit are securely fixed in the wall of the pool.

The assembly descends in the tube 28 until the peripheral margin of the plate 40 engages the flange 25 of the sleeve 23. The tube 4| is adjusted relative to the plate at the factory to properly position the lamp 60 in the focal axis 2 5 of the sleeve 23 and extends upwardly adjacent the side wall of the tube 28. The plate tormed with a recess 62 in the periphery thereof. Accordingly, the assembly can not be loweregl into the casing until the recess 62 is in register with'tihe rod 6|. The top of the rod 6| is'positioned a sufiicient height above the flange :25 so that the plate 40 must be properly positipped circumferentially before the bracket 42 enters the casing.

This is accomplished bya Push-Pul Wir me n d i e be fiB, t elewer end of which is secured in the rear of the casing section It], and the upper end of which extends into the housing 3|. The upper end of the wire 61 is formed with a convenient finger loop 63, and the lower end is secured to the reflector bracket 64. Accordingly, the reflector can be lted about the axis 65 by manipulation of wire '65! in the housing -3l'.

The housing may belprovided with aremove able. cover t'll'. To relamp the unit, it is only necessary to remove the 'cover H, remove the plug 52 from the receptacle 32, and pull the re.-

The structure of my invention avoids the necessity of diving under the water to remove the lighting unit, and of forming expensive manholes in the concrete walls of the pool. Obvi, ously, the structure may be advantageously em? ployed in floodlighting units arranged in'inaccessible places on an buildings and the like; which event the tube 28 maybe extended from the lamp --and terminate in some position venient to the workman. For outdoor installae tion, the tube 28 may be threaded, or otherwise secured directly to the casing 10. U 7
