To all whom it concern:

Be it known t at I, ERNEST OANrnLo WHITE, a citizen of the United States, residing in the borough of the Bronx of the city of New York, in the State of New York, have invented certain new and useful Improvements in Shade-Holders, of which the .brass shell sockets, the lower end having a small bead, and porcelain shell sockets having a groove near the lower end. There are now used several forms of shade holders made for attachment to the brass shell sockets, but such holders cannot be attached to porcelain sockets and, conversely, the types of holders which are applicable to porcelain sockets cannot be adapted to brass sockets, or if so attached support the shade or reflector out of proper alinement with the light source or eccentrically thereto. Further, such known holders are most diflicult of manipulation in attaching to the shell socket and in attaching the shade or reflector thereto and often cause injury or permanent distortion of the shell.

The improved holder, when attached to a shell socket, provides a firm grip with a maximum and uniform surface contact thereby eliminating such stresses on the shell as would tend to distort orbreak the same. ltalso provides a universality of application to shell sockets of all known types and insures a ready and concentric adjust- It further provides a shade holder which is of simple construction and neat in appearance.

Another object of the invention is to provide an improved adjustable support for reflectors, such as are particularly adapted for show windows and the like and in which it is desired to change the angular relation the reflector to the axis of the light.

In accordance with the first named object of the invention, there is provided a relatively flexible shell towhich the shade or reflector may be readily attached and within which is carried a flexible ring adapted to be held in a horizontal ipeeiflcation rt Letters Patent. ;Pa,te t d 1,1 6,124 1 Application filed January 14, 1920.

and to permit the angularity of the reflector with respect to the axis of the lamp to be varied for windows of different heights, depths or other proportions.

he invention will be described with greater particularity hereinafter with reference to the accompanying drawings, in which a Figure 1 is a fragmentary view in section through a shade and the improved shade holder and showing particularly the relation thereof to the shell socket and bulb.

ig. 8 is a detail view showing the relation of the adjusting screw to the adjustable arm of 'Fig. 5.

10-10 and looking in the direction of the arrows.

While it will be appreciated as the description proceeds that one of the most important features of the invention resides in the universality of adjustment of the improved shade holders to sockets of varying types and dimensions, there is illustrated in ig. 1, by way of example, a porcelain shell socket it having adjacent its lower end an.

The shade holder comprises generally a relatively inflexible shell b, of annular form carrying thumb screws 0 at suitable points for engagement with the usual heel or lip 03 at the upper edge of the shade d. The engagement anddisengagement of the shade a1 with the shell I) through axis being preferably limited in their distortion by relatively inflexible concentric shoes f secured to the inner face of the ring. The surface contact afforded between the ring f and the shell socket is of very substantial area so that a very secure gripping is effected. This unirorm and firm surface I contact is of such substantial area as to prevent the imposition of undue stresses on the shell socket a such as would tend to distort or break the same. The weight of the shade d is borne at such engaging surfaces and the security of the whole enhanced to a degree by the engagement of the shell and the enlar ement a with the lower edge of the light where it will be-most useful. Devices the thumb screws 0 will be effected m the manner commonly employed. Passing loosely through holes 6" at another section of the shell b are two diametrically alined screws 6 having enlarged heads 6 adapted to bear in the extreme inner position of the screws against the surface of the shell. These screws are in threaded engagement with a flexible ring f, and one suitable method of eflecting the engagement between the'ring and the screw is illustrated in detail in Fig. 4. As there shown the ring f carries therein a threaded bushing 9 through which the screw e passes and the inner end of the screwmay be ofi'set, as at 6 to prevent its complete withdrawal from the bushing. The ring 7 is of such diameter as to clear freely the enlarged lower end a of the shell socket on which would correspond, in the case of a metal socket, to the usual bead or external thread thereon.

The method of applying the shade holder readily to a shell socket, such as a, will be apparent. Whether or not the shade d is first attached to the shell I) of the holder, the screws e are threaded inwardly until the ring f assumes approximately its normal circular set. The holder is then passed over the shell socket a until the ring f is in alinement with the groove a, or in the case of a metal socket, is above such bead as will cor-- respond to the annular enlargement a on the shell. By setting up on the screws 6 the flexible ring f is distorted and assumes the generally elliptical form illustrated in Fig. 2, the sides thereof along the minor axis being drawn into firm engagement with the surface of the shell socket at the bottom of the groove a, and the sides along the major are rovided for locking the ring ad'ustably in xed relation 'to the shell 6. uitable means for this purpose may comprise one or more studs f secured to the ring f along an axis substantially at right angles to the axis of the screws 6 which stud or studs by manual distortion of the ring may be passed through any one of several holes f in the shell, during assembling, to give the desired angular relation b tween the reflector d carried with the shell and the vertical axis of the lamp.

As illustrated in Fig. 3, the relatively inflexible shell of the improved holder might be readily constructed so as to accommodate shades of much larger diameter. In this case there is provided a shouldered flange B of much greater diameter than the body portion B and this shouldered flange B will carry therein a plurality of thumb screws for engagement with the larger shade. In this manner, the standardization of the holder for application to shell sockets of usual dimensions may be accomplished while provision is made for attachment of shades or reflectors of varying sizes.

Another embodiment of the invention is illustrated in Fig. 5 in its association with a form of the improved shade holder showing a special adaptation for supporting a glass show window reflector made without the usual heel or li for engagement with the shade holder. l roadly considered, this support comprises a plurality of depending arms adapted to be inserted through the upper opening in the reflector, at least one of which is adjustable for the purpose of facilitating the engagement and dlsengagement of the arms with the reflector and the adjustment of the angularity of the reflector so heel or lip for engagement with supporting devices. The shade holder z' which may be of the form previously described has secured to its inner surface two dependin arms is which are relatively rigid and whic are flanged at their lower en s, as at k, to en age the inner face of the reflector at olnts adjacent its upper edge It. .In the illustrated embodiment, the third su porting arm Z is adjustably carried by the older 13 through the medium of a screw m which passes loosely through an opening in the wall of the holder 1; and may be threaded in a bushing m secured in the arm Z in much the manner. described inconnection with the construction shown in Fig. 4. The head m of the screw m is exposed to facilitate adjustment of the arm Z in a manner to be described. The inner end of the screw 'm may be upset, as indicated at m, to prevent its com lete retraction from the bushing m. The upper end of the arm Z may be confined by extending loosely through a slot 5 formed in the upper wall of the holder 2', the efl'ect being somewhat that of a hinged joint whereby free movement of I the lower end of the arm Z is permitted. At

the lower end of the arm Z may be stamped out three spaced lugsZ', Z Z on an one of which the upper edge k of the re ector may rest. For the convenience of the window trimmer each of these lugs may be stamped with a suitable legend indicating the pro er lug for the support of the reflector spending upon the proportions of the window to be lighted. is

In the use of the improved support the screw we may be backed out to permit movement of the arm Z to such a position as will enable the trimmer to pass the three arms is, Z through the upper opening in the reflector h. The flanges k of the relatively rigid arms is will then be engaged with the inner wall of the reflector h and the proper one of the three lugs Z, Z Z will be drawn into engagement with the reflector by setting up on the screw m. When the window is relatively deep it will obviously be desirable to throw the light rearwardly to a greater extent than if the window be shallow and to attain this end the reflector It will be inclined at a substantial angle with respect to the axis of the light source a. In this case, the rearmost portion of the reflector It will be tilted upwardl gaging the uppermost lug Z on t e arm Z with the reflector. For windows of medium depth it will be desirable to decrease the by enangular relation between the reflector and the light source a, and in such case the second lug Z will be used for the support of the rearmost portion of the reflector, as indicated in F1 5. For shallow windows where the lig t is to be focused more di rectly downwardly the lowermost lug Z is used as the support. By providing an adustable arm, such as Z, and properly graduatmg the lugs Z, Z, Z for windowsof dif- -ferent dimensions, the personal factor is discounted and the trimmer will select the appropriate lug accordingto the directions. I A further feature of the invention which is important in fixtures used for window lighting where the space is cramped resides in the accessibility 0 all of the parts which must be manipulated. The thumb screws 0 which are employed for drawing the flexible band 0' into firm surface contact with the shell socket p will be placed on an axis extending substantially at right angles to the axis 0 the screw on and in a plane parallel to the window ane so that the holder may be readily attac ed to the shell socket. The screw m will be placed in the holder 11 at the side remote from the window pane so as to be readily accessible to the window trimmer. These advantages result from the peculiar character of the improved devices and become of considerable practical importance in the art. In this form of shade holder a stud o isshown on the ring 0 for engagement with the shell i, it being .contemplated that the shell shall be fixed in a horizontal position while the reflector shall be adjusted angularly in the manner de scribed.

The holder shown in Figs. 9 and 10 may be substantially like that shown in Fig. 1 105 including a relatively inflexible shell 12, a flexible band 12 carried therein and adapted to be drawn into en agement with the shell socket by means 0 diametrically opposed screws said flexible ring carrying dia- 110 metrica ly opposed studs p which may be engaged with any one of a series of holes 12' formed in the shell at opposite sides thereof and in the same vertical plane with the studs 79 ;When the studs 12 rest in one set of 115 holes 12, as shown in Fig. 9, the shell will be held in a horizontal position. If the studs 17 are retracted from that set of holes and the shell 79 tilted about the screws in one direction or the other, the studs will 120 be engaged with another set of holes for the purpose of fixing the shell in such angular position. Hinged to the shell p are a series of pendant arms 9 which may, conveniently, be four in number and arranged mounted on the arms 9 is a clamping'ring 8 provided with holes. 8' therein throu h which the arms extend loosely, respective y, and preferably formed with a flan e s to overliethe outer surface of the reflector 1* when the clamping ring is in position. The ring 8 has a central opening 8 therein to receive the lamp t. 1

The adjustment of the angular relation of the reflector r with relation to the axis of the lamp t is secured in this embodiment? in somewhat different manner than in the embodiment shown in Fig. 1 in which the reflector d is fixedly secured to the shell. In adjusting the angular relation of the reflector d shown in Fig. 1 with relation to the axis ofthe lamp the reflector will swing about the screws e as a center. In adjusting the angularity ofthe reflector 1' shown in Fig. 9 the reflector will swing about its own center of gravity in assumin an angular position with relation to the axis of the lamp. In effecting the adjustment, assuming that the arms 9' are disengaged from the reflector r the shell p will be locked in the horizontal or in the desired angular position to give the resulting inclination of the reflector-1' for the most useful reflectionof light depending upon the character of the window. For instance, when the shell p is in a horizontal position, as shown in Fig. 9, the ring 8 may be slid upwardly along the arms 9 to move the lower ends of these arms inwardly, the

diametrical distance between the holes 8' in the ring being less than the diameter of the shell 12, whereby the arms 9 are inclined downwardly and inwardly at all times. The result is that when thering s is moved upwardly along said arms the latter have their lower ends moved toward one another. The reflector 9 will then be moved into position to receive the ends of the arms through its upper opening and the clamping ring 8 then moved downwardly to throw the lower end of said arms outwardly and into engagement with the inner surface of the reflector as shown in Fig. 9. The final movement of the clamping ring 8 to bring the flange 8 into engagement with the outer surface of the reflector r serves to clamp all of the arms 9' in fixed engagement with the reflector 7- so that the latteris securely held in place. The illustrated embodiment has shown a reflector of such form that when the shell 2 is fixed in horizontal position the reflector will throw the light somewhat rearwardly of the vertical axis of the lamp as would be desirable in display windows of medium depth. In this case, one of the pendant arms V6 may be shorter than its op posite arm. hen the shell 30 is tilted up and the studs enter into holes in the shell along the line indicated at tt, the arm 2 will be lowered while its opposite arm Wlll be raised and the reflector 1' will swing about at ed that changes in directly downwardly, as would be esirable in a shallow window. When the shell p is tilted in. the opposite direction about the screws p through the studs p alon the line indicated at uu, the arm will e raised to the position indicated in dotted lines and its opposite arm will be lowered correspondingly and the reflector 1' will swin about its center of gravity into such a osition as is indicated by dotted lines, there throwing the light wellt'o the rear as would be desirable In a deep window. The 0 enings s in the clamping ring 8 through which the various arms 9, g extend are of such sizeas to permit the clamping ring to conform to the tilting'of the reflector 1' while being mov able into such relation tothe upper edge of the reflector and the arms as to lock the latter in engagement with the reflector.-

While the improved support for window reflectors has been shown in association with the improved shade holder and while many advantages 'res'ult'from the adaptation of one to the other,it is to be understood, as is evident from the difierent embodiments illustrated, that one may be used to advantage without the other. It will also be appreciwill suggest themselves to skilled mechanics,

details of construction but all such departures involving expediency only are to be deemed within the scope of the invention provided the desired results are obtained from devices which employ the principles described.
