ELECTRICAL LIGHTING FIXTURE 2 Sheets-Sheet 2 Filed Feb. 5,- 1957 95 Fig. 8

Inventor John J. -l'rara/e' B y and United States Patent This invention relates to new and useful improvements in lighting equipment and the primary object of the present invention is to provide a novel and improved lighting fixture or lamp for vessels although the same is not restricted solely for use with vessels.

Y3? n ther important object ofthe present invention is to provide a light fixture holding a lamp and embodying novel and improved means for connecting electrical conductors to the lamp so that the conductors may be serviced in a cnnvenient manner.

Another object of the present invention is to provide an attachment for lamp casings supporting cable blocks that are applied to cables entering the attachment in order to eliminate the heretofore unsafe and unsatisfactory method of extending cables through the casing.

Another very important object of the present invention tisto provide an attachment for lamp casings including an angle member securedto and spaced from the outer periphery of a lamp casing to define a ventilating opening between the casing and the angle member to maintain the angle member, which supports a cable block, at a lower temperature than the casing thus providing an important supply feature by protecting the wiring from excessive heat.

Another feature of the present invention is to provide a lamp attachment of the aforementioned character that can be formed during the formation of a lamp casing, fixed to a lamp casing after the latter is produced, or detachably secured to a lamp casing, thereby facilitating the use of the instant attachment on existing lamp casings as well as during the manufacture of lamp casings.

A further object of the present invention is to provide a lamp fixture that is simple and practical in constguction and extremely neat and attractive in appearance.

A still further aim of the present invention is to provide a lamp casing that is small and compact in structure,

strong and reliable'in use, durable and efficient in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanying drawings forming part hereof, wherein like tially on the plane of section line 3-3 of Figure 2;

Figure 7 is a bottomplanview of the present attachment in further modified form;

Figure 8 is a diametrical vertical sectional view taken substantially on the plane of section line 8-8 of Figure 7;

Figure 9 is a plan view of the present attachment in still further modified form;

Figure 10 is a vertical sectional view taken substantially on the plane of section line 10--10 of Figure 9;

Figure l l is a fragmentary vertical sectional view taken substantially on the plane of section line 11--11 of Figure 2; and,

Figure 12 is a view similar to Figure ll and showing the manner in which the attachment is applied to the casing in slightly modified form.

Referring now to the drawings in detail, and more particularlytto Figures 1-4 inclusive and 11, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral 10 represents atcylindrical casingor lamp holder of any suitable size and materialhaving a lower open end 12.

Suitably secured to the upper wall or closed end 14 of the casing 10, is a lamp socket 16 receiving a lamp 18. The lamp 18 is embraced by a substantially tubular or sleeve-like reflector or light director 20 whose lower enlarged end portion 22 is suitably secured to a retaining ring 24 that is fixed within the casing 10 adjacent the end portion 12.

A face plate or retainer ring 32 is detachably secured to the casing 10 by fasteners or the like 34 that extend through the plate 32 and into the ring 24 or ears (not shown) which are fixed within the casing. The face plate 32 is centrally apertured to receive a concavo-convexed transparent or translucent disk 36.

The above described structure has been heretofore used previously in conjunction with vessels and the cables associated with the casing were extended through openings in either the wall 14 or the sides of the casing thereby requiring separate removable panels in the ceiling adjacent to the lamp. The removal of these panels provided access to the cable blocks and wiring. The wiring was then carried from the cable blocks through the casing ofthe fixture. The panel did not give access to the interiorof the fixture. Access to the interior of the fixture was obtained by removing the cover andinte'rnal parts of the fixture thusallowing only a limited amount of space in which 'towork. l

The use of access panels is extremely undesirable as well as the awkward method of repairing and servicing the cables, therefore, his the principal feature of the present invention to eliminate the foregoing objections by providing a simple attachment for the casing.

To accomplish the desired results,- there is provided an annular or continuous angle member 38 having a horizontal leg portion 40 and a vertical leg portion 42. The inner edge 44 of the leg portion 40 is spaced from the outer periphery of the casing 10 and a plurality of circumferentially spaced ears or lugs 46 project: radially from the edge 44 and are detachably secured by fasteners or the like 48 to suitable brackets or angle members, 50 that are mounted on the casing 10.

The lower edge 52 of the vertical leg portion 42 bears upon the face plate 32 and the leg portion 42 is spaced substantially parallel to the casing 10 to define a channel 54 completely surrounding the casing.

It should be noted, that there is a definite, and essential feature established by-placing the edge 44 from the easing 10 since the air openings or ventilating openings .56 so formed willretainthe channel 54. relatively cool although the, casing will be warm orheated when the lamp 181s energized. This will protect important wiring from excessive heat thus providing safety of construct on as well as safety .to those handling the attachment or support 38.

Removably secured to the inner or lower face of the leg portion 40, is a plurality of cable blocks 58 having fasteners or contacts 60 that receive conductors-61 The conductors 62 are connected tothe socket 16 so that the lamp 18 will be energized when a circuit is coupled tothe conductors 62.

The leg portion 40 is provided with any suitable num- 60 to complete a circeiling 72, such as the ceiling of a vessel so that the face 7 plate 32 bears against the lower surface of the ceiling.

The leg portions 40 are secured to suitable, adjustable hanger brackets or arms 74 that depend from an upper floor or deck 76.

Attention is now directed to Figures 5 and 6, wherein there is disclosed the present attachment 78 in slightly modified form. In this embodiment the attachment is mounted on the casing as previously described, however, additional ventilating openings are provided in the form of peripheral notches 80 placed in the inner edge 82 of I the horizontal leg portion 84.

Since the cable blocks 86 are secured to the leg portion 84, the same are also provided with notches or concaved recesses 88 that Will not block the notches 80 adjacent the said blocks.

Figures 7 and 8 show the attachment 90 for the casing in further modified form. In this construction, the angle member or attachment includes a horizontal leg portion 92 having a scalloped inner edge in order to form a series of recesses 94 that are relatively close together in order .to provide additional ventilating means for the attachment.

Cable blocks 96 are secured to the inner face of the leg portion 92 and the cables are extended through suitable openings 98 provided in the leg portion 92.

Reference is next directed to Figure 9 which illustrates :the attachment 100 as being a rectangular or square angle member for use with a square or rectangular casings.

The inner edge 102 of the horizontal leg portion 104 nected to cable blocks 108 fixed to the inner face of the leg portion 104.

Figure 12 illustrates the present attachment 110 as being integrally formed with the casing 112. In this con- ;struction, which issimilar to that disclosed for Figures 1-4 inclusive, as far as the placement of parts, the lower edge of the vertical leg portion 114 bears upon the face plate 116 and the horizontal leg portion 118 is suitably apertured to provide the necessary ventilating openings for the. channel 120. I

The cable 122 is secured to the leg portion 118 and is connected to conductors extending from the socket 124 through the medium of cable blocks (not shown) that are mounted on the leg portion 118.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary. d

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as hereffn described .and the scope of the appended claims.
