A split collar 1'6 is integrally connected "to the vertical webs' M and isprov'i'ded with cooperating lugs or bosses I! to accommodate a screw or bolt IE to 'lock the two-parts together. The parts II and li2 may -'beprovided with emensions or lips 19 on one .';section', which are adapted to be re'ceived'fin corresponding depressions '29 formed in the other section, whereby the parts are in'terfitting or -interlocliiriglyconnected together. The halves l'l --'an'd l.2.mayfbe provided with substantially'semicirculare'a'rs or lugsZl arranged to form a split ningi22 at the upper partof theguard lnfFig's. "3 and 4, w here the two serni-circular parts {are placed together. These ears 2! flare upwardly :and outwardly to provide, in effect, an annular groove .23 to receive a locking washer or ring 24. Thegua'rd Iill'may be spread apart, Fig. 4,- so'as to p'ermitithe insertion or removal of a lamp g-lobe .oriaqreflector- 25, or-the :guard may'be completely .adismantledl' "The screws l 8 are'loosened and rerr'nove'd to permit the parts 'l l and 12 to be spread apart to install or remove :a lamp or shade, the .zears 2sl :andthe :was'her 24 actingas a hinge connection. Also, the outwardly flared ears 2| xernay" be islid outwardly from underneath the ."washert 2A to tdisjoin or un um t ,pafts 1 and I2.

The shade or reflector 25, of any desired form or configuration, is fastened to an upstanding threaded member 26 which extends through an opening 21, Figs. 3 and 5, formed in the upper part of the guard at the ears or lugs 2|. The shade or reflector 25 is fastened to the member 26 in the manner shown, such as by peening or upsetting the lower end, as indicated at 28. A washer element 29, Figs. 3 and 5, is arranged between the upper surface of the shade or reflector and the underside of the guard at the top thereof to permit free revoluble movement of the shade inside of the guard. A lock nut 30 threadedly engages the stem 26, and its purpose is to lock the shade in adjusted position. The lock nut 30 is provided with a bevel portion or cone-shaped end 3| which is adapted to fit down in the seat about the opening 21 when the lock nut 30 is screwed home so as to spread the halves outwardly at the top of the guard l0, pressing the ears 2| outwardly against the ring 24 and thereby locking the two parts at the upper end in positive engagement. In order to change the position of the shade, the lock nut 35 is loosened sufficiently on the threaded stem 26 so as to permit the shade to be rotated in the guard ID by operating a knob 32 on top of the threaded member 25, Figs. 1 to 4. The shade or reflector 25, the stem 25, the thumb nut 30, and the member 32 act as a unit. When the thumb nut 30 is loosened sufii- I ciently, the entire unitary structure can be ro.-,

movement of the shade in the guard. A lock nut 53 having a cone-shaped end threadedly engages the stem 54 of the hook 49 and bears against the disk 41. To prevent the turned ends 48 of the vertical wires from interfering with or obstructing the operation of the shade the washer 52 is interposed between the ends 48 and the top of the shade. When the lock nut 53 is tightened, the washer 52 will be forced against the ends 48 of the wires and lock the shade in adjusted position. To shift the reflector 25, the lock nut 53 is loosened sufiiciently to permit the hook 49 to be rotated to move the shade to its new adjusted position. The guard 40 is shown clamped about a rubber handle 55, Figs. 6 and '7.

To insert the reflector or shade within the intated within the guard l0, thereby adjusting the shade or reflector to any desired position about the central stem 25. After the shade is arranged in adjusted position, the thumb nut is then operated again to lock the parts securely in place and to hold the shade in adjusted position.

A hook 33, Figs. 1, 3 and 4, may be fastened to a part of the guard H] to permit the guard to be hung from a support. This hook 33 may be rigidly connected to the guard, or it may be revolubly mounted, as desired. However, a hooking element may be provided, Fig. 5, by providing a hook 34 on the threaded member 26. This may be accomplished by elongating the member 28 and bending it in the form of a hook, as shown in Fig. 5, whereby the hook 34 will operate in place of the knob 32, the lock or thumb nut 30 being threadedly mounted on the threaded portion 26 which constitutes the stem portion of the collar 44 which is formed of two parts and con-- nected together by screws 45 passing through ears 46, Fig. '7. The upper ends of the vertical wires 4| extend through holes provided in a disk 41 and are bent inwardly to locking engagement, as

indicated at 4B. The upper ends of the vertical wires 4| have free movement in the holes of thel disk 41 to permit pivotal movement of one-half of the guard with respect to the other half. .A hook 49 passes through an opening 50 formed in the center of the disk 41 and is secured'to the reflector 25, as indicated at 5|, Fig. 7.. A washer 52 is arranged between the turned ends 48 of the wire and the upper surface of the shade or reflector 25 to permit free revoluble 1 distance to permit the insertion of the lamp as well as the shade.

The invention comprises a shade element arranged inside of the guard and thereby being fully protected and prevented from injury. The "shade or reflector can be shifted to any desirable position within the guard by merely operating a lock nut to loosen the elements and then turning a stem which is connected to the shade;

' Changes may be made in the form, construction and: arrangement of the parts without departing from the spirit of the invention or sacrificing 35. any of its advantages, and the right is hereby apart and comprising a shade or reflector element arranged: interiorly thereof, a pair of upwardly and outwardly extending ears on the guard at the upper end thereof which when the two parts of the guard are together in closed position form a split collar having an outer annular groove, a washer element about the ears and arranged in the annular groove, said ears having semi-circular openings therein whereby a circular concentric opening is provided when the two'parts of the guard are together in closed position; a threaded stem on the element extending through said opening and projecting above the top of' the I guard, and a lock-nut threadedly engaging the stem and spreading the ears outwardly against the washer and. frictionally locking the element in'place, said stem being adapted to be turned to shift the position of the element when the locknut is loosened.
