Ul lE' tD STATES ATENT OFFIQE HARRY YALE MAGEOCH, OF PHILADELPHIA, PENNSYLVANIA, ASSIG-NOR TO ELECTRIC SERVICE SUPPLIES COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORA- TION OFIPENNSYLVANIAF Application filed June 16,

This invention relates to light distributing units and more particularly to lighting units especially adapt-ed for the purposes of hlghway and flood lighting. i g

It is among the primary objects of thls invention to provide an exterior lighting device which serves not only to illuminate the high- 7 way but also to flood-light adjacent buildlngs, the device beingconstructed in the form of a compact unit embodying two sourcesof light, one for the purpose of highway illumination and the other for the purpose of flood-lightit further object of the invention is the provision of a combined highway and flood-lighting unit embodying two separate and dist nct sources oflight, that source which is utilized for highway lighting purp'oses being fixed in position while that which is designed for flood-lighting purposes is mounted independ-v ently of the former and in such manner as to afford a wide range of movement through which the'rays of light emanating from said flood-lighting source may be directed. A still further object of the invention is the provision of an adapter for pivotally mounting a flood-lighting unit within a highway illuminating device, said adapter being arranged to support a reflector and a lamp in such manner that the latter bear a constant fixed relation to each other irrespective of the adjusted position of the flood-lighting unit as a whole, the result being that the flood-lighting lamp is at all times in proper focus with respect to its reflector so as to distribute the light more efliciently and effectively. 7 Other objects and objects relating to details of construction and economies in operation will appear more fully hereinafter.

The invention consists substantially in the combination, construction, location and relative arrangement of parts, all as will be de P scribed more fully hereinafter, as shown in the accompanying drawings illustrating a preferred form thereof, and as finally pointed out in the appended claims. In said drawings:

highway lighting unit embodying the principles of this invention;

Figure 2 is a sectional view taken on the line 22 of Figure 1;

Figure 3 is a sectional View taken on the line 33 of Figure 1; and

Figure 4 is a side elevation of the complete unit shown in Figure 1. 7

Referring now to the drawings and more particularly to Figures 1, 2 and 3 thereof, it will be seen that the invention has been embodied in a highway lighting unit, designated generally by the reference numeral 10. This unit 10, which is mounted upon a suitable standard 11, comprises a pair of lower annular members 12 and 13 secured together by the securing elements 14. EX- tending upwardly from the upper edge of the annular member 13 are a. plurality of arm or strap members 15 spaced equidistantly about the periphery of the member 13, the lower ends of these members 15 being preferably secured to the member 13 by means of the screws 16.- Secured to the upper and free ends of the strap members 15, preferably by the screws 17, is an annular member 18, the upper edge of which con stitutes a seat for the top or cover 19 of the unit. Preferably this cover 19 is hingedly secured to one side of the member 18, as at 20. (See Figure 4.)

The external appearance of the unit is of course immaterial in so far as the present invention is concerned, the particular shape being dependent entirely upon the number and form of the strap members 15. In the present instance, however, the unit 10 is of octagonal form and is provided in the sides thereof with a plurality of translucent glasses 21 secured in position in any suitable manner. The hinged cover 19 may likewise be provided with translucent glasses 22 therein or said cover may be constructed of opaque material throughout if desired.

As appears most clearly in Figures 1 and 3, the lowermost annular member 12 is provided with a centrally apertured bottom 23 across which is secured, preferably by the screws 24, a lamp socket supporting yoke 25. Rigidly mounted upon this yoke 25 in tially spaced elongated slots or openings 28 1 through which pass the mainmounting bolts 29, the arrangement being such that when 7 these bolts 29 are loosened the unitlO may be rotated with respect to the standard 11 Within the limits of the slots 28. Secured to and extending downwardly and inwardly from the uppermost annular member 18 are a pair of diametrically opposed supporting brackets 30,. the lower ends of which are provided with threaded apertures. 31; It is between these brackets that the flood-lighting adapter is pivot-ally zmounted. As appears mostclearly; in

. ures 1 and 2, this adapter comprises-a substantially U shaped strap 32 to which is secured, preferably by welding-a second strap 33, the straps 32and 33 being arranged sub stantially at right angles to one, another. The free ends, of the U-shaped strap 32 are each slotted, as at 34, to facilitate the mounting of the adapterv upon the supporting studs .35 which are threadedly received within the apertures 31. "If desired, one or more additional slots 34' may be provided for the purposeof shifting the adapter laterally into. a position such as is indicated by'the dotted line 34 in F i'g.; 1. Preferably, the slot 34 is of greater depth than that of slot .34 so that when the former slot is used the adapter mayassume a lowered as well as laterally adjusted position. To; remove the adapter it is only necessary to loosen the studs'35 whereupon the adapter may. be gifted bodily from the supporting brackets will be observed that the strap 33 is lon gitudlnally curved, as at 36, substantially equidistantly to either side of its point of connection with the supporting strap 32 and that from the upper end of this curved portion 36 the strap continues in the form of an angular extension having the branches 3? and 38.

Provided inthe branch 37 is an opening 39 arranged to permitthe passage therethrough of sponds in longitudinal cross section to the cur- V a winged stud 40. The lower end; ofzthe curved portion 36 of the strap 33 is reversely bent as at 41 to'form a receiving channel for the lower edge. ofa reflector 42 which correvature of, the curved strap portion 36. The baseof the U shaped strap 32 is curved to correspond to the transverse curvature of the refiector 42. '(See Figure 2.) The upper edge of this reflector is'retainedagainst displacestud 40. Preferably,the strap 33 is provided with two or more spacing pads 44 which may be spot welded to the strap andbetween which and the rear surface of the reflector may be disposed the felt pads 45. The reflector 42 is retained against lateral displacement by the legs of the U-shaped supporting strap 32, the

arrangement being such that when the retaining clip 43 is removed or turned through an angle of'subs'tantially 90 degrees from its position shown in Figure 1, the reflector maybe readily inserted into proper position with one edge thereof seated within the reversely.

bent end of the strap 33. The clip 43 may then be positioned as shown with one end thereof overlying the opposite edge of the reflector andthe winged stud .40 tightened to Secure said edge againstdisplacement. 7

Bigidly secured to the branch 38 of the strap 33 is a lamp socket 46 for reception of a second lamp 47,'this latter "lamp being the source of lightfor flood-lighting purposes. By reason of the fact that the socket 46 and the reflector 42 are both mounted upon a common support, the focus of the flood-lighting lamp 47 bears aconstant and fixed relation to thereflector 42. Once the'proper focal relation be determined it need never, and in the present instance cannot be disturbed irrespective of the position to which" the flood-lighting unit as a: whole may be shifted. I

It willbe apparent from the foregoing that this invention provides a flood-lighting arrangement capable I of ready and simple .mounting in a highway lighting unit wherein the focal relation between the flood-lighting source and its reflector is at all times fixed at the same time that the flood-lighting unit as a assume. At the same time, it will be seen that the flood-lighting unit is capable .of being readily removed from its main supports without disrupting its organization or disturbing the focal adjustment between the light source and its reflector. 7

It will, of course, be understood that varis ous changes may be made from time to time in the general arrangement of this invention without departing from the spirit or principles thereof, and it is accordingly intended to claim the same broadly as well as specifically as indicated in the appended claims. a ment by means of a retaining clip 43, the body of which is threadedly engaged by the winged What is claimed as new and useful is: 1.
