Specification of Letters Patent.

L'mr.

Patented Nov. 15, 1921.

Application filed March 3, 1919. Serial No. 280,424.

To all whom it may concern:

Be it known that I,-JoHN J. REKAR, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in-=Lamps, of which the following is a specification.

This invention relates to a lamp and particularly pertains to an electric lamp of the type especially adapted for surgical purposes.

It is the object of this invention to provide a lamp embodying a housing for carrying an electric light bulb constructed to vent heat generated by the bulb and maintain a flow of air around the lamp socke't soas to obviate overheating the socket connection of the bulb.

Another object is to provide a housing having angularly disposed reflectors arranged to direct and concentrate light rays emitted from the bulb.

Another object is to provide an adjustable support for the lamp housing whereby it may be disposed on various horizontal planes turned horizontally and disposed in various positions around a horizontal axis.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which:

Figure l is a view of same in side elevation with parts broken away.

Fig; 2 is a detail in perspective of the clamping sleeves with portions broken away.

Fig. 3 is a view in vertical section and elevation of the lamp housing illustrating the arrangement of reflecting surfaces therein and showing the vent construction.

The supporting portion of the lamp embodies a base 6 .of any suitable construction on which is mounted a standard 7. This standard is preferably formed of tubing and made in two parts 8 and 9 with the portion 8 rigidly secured to the base 6 and carrying on its upper end a vertical pivot 10 extending into the lower end of the portion 9 to form a pivotal mounting for the latter whereby the standard may be rotated relative to the base.

Mounted on the standard for vertical adjustment thereon is a split sleeve 11 having opposed lugs 12 engaged by a wing bolt 13 whereby the sleeve may be clamped against movement on the standard. Formed on the sleeve 11 and extending at right angles thereto is'a second split sleeve 14 formed with opposed lugs 15 engaged by a wing nut 16 whereby the sleeve 1 1 may be expanded or contracted and clamped on a horizontal corss arm 17 extending through the sleeve 14 and adapted to be turned to various positions in the latter. 7

The cross arm is engaged intermediate'its ends by the sleeve 14 and one of its terminals is provided with a handle 18 by which it may be readily turned to any desired position when the sleeve is loosened thereon.

The other end of the cross arm carries a lamp housing 19 which housing includes a cylindrical flue casing 20 formed with an outwardly tapered flange 21 on its lower end terminating in an annular flange 22. A bracket 23 is secured to the flange 22 and is formed with a clamping sleeve 24. adapted to be removably secured to the end of the cross arm 17 by a wing bolt 25. A

The flue casing 20 is provided with a re movable end cap 26 attached thereto by screws 27 and which cap is formed with a pair of dependent ribs 28 to which is secured b screws 29, a mo 1 socket 30 of any suitable construction a d apted to detachably engage with the base 31 of an electric light bulb 32 and to provide electrical connections between the terminals of the incandescent filament in the light bulb and a pair of electrical conductors 33 connecting with electrical contacts in the socket and preferably passing through an opening in the casing.

The flue casing 20 encircles the socket and the upper portion of the light bulb in spaced relation thereto to form an air passage 34 and the walls of the casing are formed with vent openings 35 through which warm air within the casing may be discharged and thus permit the circulation of cool air around the socket and base of the light bulb to prevent overheating thereof. The tapered flange 21 is formed with air inlet openings 36 for admitting cool air to the lower portion of the passage 34 to displace the warm air discharged through the vent openin s 35.

ecured to the ed e of the flange 22 and divergin downwar ly therefrom is a frusto-conica wall 37 extending to a point prefably a short distance beyond the filament in the bulb. The outeredge of the wall 37 connects with a cylindrical wall 38 opening a short distance below the bulb. The walls 37 and 38 constitute a shade and their inner faces are .silvered to form an outwardly inclined reflecting surface 39 on the inner face of the wall 37 and a vertical reflecting surface 40 on the inner face of the cylindrical wall 38.

A counter reflector 4:1 is arranged within the space encircled by the reflector 39 adjacent to the flange 22 and is of inverted frusto-conical form and arranged with its base abutting against the upper portion of the reflector surface 39. The reflectors 39 and 41 are disposed in such angular relation to each other and to the light bulb as to cooperate in directing in a downward direction the major portion of the lateral and upwardly divergent light rays emitted from the light bul The inner edge of the counter reflector is spaced such distancefrom the light bulb as to permit an upward flow of air around the bulb and into the passage 34. s

In the operation of the invention when it is desired to adjust the lamp vertically the sleeve 11 is moved toany desired position on the standard and rigidly secured thereto by the wing bolt 13. When it is desired to dispose the lamp in an inclined position the cross arm 17 is turned in the clamping sleeve 14 and rigidly engaged thereby by tightening the wing nut 16. The lamp may thus be disposed at various levels and turned to various positions around a horizontal axis. By rotating the upper portion 9 of the standard, the lamp may be disposed in any desired position around a vertical axis.

clamp-sleeve and extending at right angles.

thereto, a cross arm slidably carried intermediate its ends in said last named clampsleeve and adapted to be held against turning thereby in varlous positions, a lamp shade carried directly by said cross arm and opening at right angles thereto, an electric lamp encircled-by said shade, and a handle on the other end of said cross arm whereby the cross arm may be rotated axially to dispose the lamp and'shade in various positions.

2. In a lamp, the combination of a socket, an electric light bulb carried in said socket, a perforated casing encircling said socket, and spaced therefrom forming a heat venting flue, an annular fian'ge on said casing, a frusto-conical reflector on said flange diverging downwardly therefrom, and a counter reflector of frusto-conical form inverted within the first named reflector and depending from said flange.

, 3. In a lamp, a horizontal cross arm, .a lamp shade carried directly on said cross arm and opening at right angles thereon, an electric lamp encircled by said shade, a clamp sleeve in which said cross arm is slidably carried intermediate its ends for longitudinal and circumferential movementand adapted to be held thereby in various positions, and a support for said clamp sleeve lntegral therewith mounted to turn on a vertical axis.
