STATES PATENT CHARLES PARADIS, OF MONTREAL, QUEBEC, CANADA.

ILLUMINATING DEVICE.

Application led July 17, 1923. Serial No. 652,174.

To all whom t may concern.'

Be it known that I, CHARLES PARADIS, subject of the King of Great Britain, residing at Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Illuminating Devices; and I do hereby declare thatthe following isa full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in illumination, having for an object to provide an improved illuminating device of the flood type, particularly advantageous for use in the illuminating of townships, cities, etc., without the necessity of the usual street lamps and similar devices now prevalent.

It is also an object of the invention to provide an illuminating device, which, in itself, will afford an ample source of light for the streets or other ways of a city, town or the like, during darkness, and which will reduce to minimum the presence of shadows with the resultant absorption of night.

Other objects will be in part obvious and in part pointed out.

In order that the invention and its mode of operation may be readily understood by persons skilled in the art, I have, in the accompanying illustrative drawings, and in the detailed following description based thereon set out one possible embodiment of the same.

In these drawings:

Figure 1 is a perspective view of the improved device showing its mode of use;

Figure 2 is a fragmentary vertical longitudinal section through the same;

Figure 3 is a detail in elevation showing the relative arrangement of light sources or lamps and their respective reflectors within the device; and,

Figure 4f is a fragmentary transverse section showing the manner in which the various lamps of the device are electrically interconnected.

Having more particular references to the drawings, in connection with which like characters of reference will designate corresponding parts throughout, the invention may be stated to comprise a lamp casing or housing generally indicated by the numeral 1, formed of sheet metal or other suitable material and being of a proportion corresponding to the area to be illuminated thereby. The forward end of the casing 1 is flared as at 2 and is open in order that the rays of light will be directed therefrom in divergent fashion and in consequence be directed over the area to be illuminated with maximum efficiency.

The housing l is preferably formed in sections, three in number, and include a rearward section 3, an intermediate section 4 and a forward or flared section 5, marginal flanges being formed upon each of these sections whereby to receive bolts or other suitable fastening devices, as indicated at 6 for securely or positively interconnecting the juxtaposed sections. The intermediate section 4 carries bearing spindles 7 upon its opposite sides, which, in turn, are rotatably engaged in the opposite extremities of a bifurcated supporting bracket 8 having a dependent stalf which rotatably receives therein a supporting post 9 arranged upon the platform of a tower 10 or similar elevated structure.

The rearward section 3 is formed with a way which is of a size suflicient to admitan attendant or operator and is normally closed by mea-ns of a horizontaly swinging door 11, a ladder 12 being preferably adjacent one side wall of the section 3 for obvious purposes. Upon the upper flared wall of the section 5, a plurality of transversely aligned shutter adjusting wheels 13 are mounted and have independent connection with shutters (not shown) arranged adjacent the upper end of said section 5 whereby the transmission of light therefrom may be accordingly controlled.

The adjacent marginal portions of the sections 3 and flare formed with internal flanges 14 which receive therebetween a wall 15, affording means for supporting a plurality of electric lamps 16 of extremely high candle power. Certain of these lamps 16 are provided with conical reflectors 17, while those lamps intermediate the conical reectors are provided with reflectors 18 which are substantially square in cross section. By this novel arrangement of reflectors 17 and 18, it will be appreciated that the entire wall 15 will be provided with a reflecting surface for reflecting light rays emitted from their respective lamps 16 and thus, cause a projection of such rays forwardly from the flared open end of the section 5 of the housing 1 over an area to be illuminated with maximum results.

Electrical conductors 19 are arranged in troughs or Ways 2O upon the reverse side of the Wall 15 and, as Will be understood, are accessible -from Within the section 3 of the housing 1, thus permitting of ready repairing of the lamps or their respective conductors as may become necessary.

As hereinbefore stated, the illuminating device is preferably arranged upon an elevated tower 10, this tower being provided with a ladder 21 to facilitate ascension thereon, While a platform 22 is arranged at its upper end and communicates With the section 3 by Way of anotherl ladder 23. lt is, of course, to be understood, in this connection, that the tower 10 is of a height Which will permit the same to be arranged at a considerable distance above the buildings Within the city or town to be illuminated thereby, so that with energization of the various lamps 16, the light rays transmitted therefrom will fiood that area overlying the city or town and by consequence, certain ot the rays trom this illuminated area will be retracted in their course of travel and Will afford ample illumination for the streets ot such city or town.

In order that the illumination oit the city or toivn may be regulated, it is only neces sary to adjust the shutter operating Wheels 13, which Wheels, in turn, will actuate their respective shutters in a manner to regulate the supply ot light in their particular Zone corresponding thereto.

Manifestly, the construction shown is capable ot considerable modification and such modification as is Within the scopeof my claims, I consider Within the spirit of my invention.

Having thus fully described the invention,

What I claim as new and desire to protect by Letters Patent is zl.' A device of the character described comprising an elevated structure, a housing adjustably supported on said structure, having a flared inward end, illuminating means Within said housing, and individual retlectors for said illuminating means, certain ot Which are conical and others of which are square and arranged intermediate said conical reflectors.

2. A device of the character described comprising an elevated supported structure, a sectional housing adjustably supported thereon, having a fiared open end, illuminating means arranged Within the housing, and individual reflectors tor said `illuminating means, comprising conical and square reflectors, the square reflectors beingarranged intermediate the conical refiectors, as and Jfor the purpose set forth.

3. A device ot the character described comprising an elevated structure, a sectional housing supported on said structure having a fiared open end, a door Way in the opposite end of the housing, the adjacent portions of said sections of the housing being flanged to receive bolts therethrough, internal ianges formed on certain of the adjacent marginal portions of said sections, a wall supported between said internal flanges, a plurality ot lamps arranged on said Wall connected with a source of power, a plurality of conical reflectors for certain ot said lamps, and a plurality of square reflectors for the remaining and intermediate lamps, said square reflectors being arranged .rearwardly of and intermediate said conical reflectors.

In Witness whereof' l have hereunto set my hand.

CHARLES PARADIS.
