" simian on REFLECTOR ATTACHMENT.

To all who'm' it mai concern: I

Be it known that I, HENRYDOLIER, J r.,

a citizen of the United" States, residing-inthe city of Philadelphia, county of Philadelphia, and State "of Pennsylvania, have inventedcertain new and useful Improve ments 'in' Shade or Reflector -Atta'cl'nnents, of which the following 'isfa specification.

My invention relates to means for sup porting a shade or reflector in proximity to a source of light, and relates more' particularly to an attati'hment for supporting a shade or reflector upon an electrical in'-' candescent l'amp socket, particularlywhen said shade or reflector is comparatively heavy, as when made of glass'or other vitreous material. i

It is the object of my invention to provide" an attachment for the purpose above stated, which shall be. simple, cheap to man ufacture, easily attachable to the support and reflector, and which shall be capable of making asecure attachment to the reflector irrespective'of variations in size 'or dimensions of such reflector incident to its manufacture. v v 1 For an illustration of one of the forms my invention may' ta l1:e, reference is to be had'to the accompany ng draW1ng,1n;wlnch:

Figure 1 is a vertical elevational view of an incandescent lam and its socket', the shade ort'reflecto'ran its attachment being shown in section. Fig. 2 is a horizontal sectional view taken on the line 22 of Fig.

1 showing the attachment in locked. or re-- larhorizontal sectional -view but with the parts in the open position. F ig. t is afragm at i bead wl e mentary elevational view'illustrating means for indicating the relati ve positionofparts.

Supported by androtatable upon the menu ber g. is the lower cam member 7: having its upper edge turned inwardly and embraced flange or lip of'thc memberfi', so as't-o sup port the member Zf upon the member g and allow the rotation of the member In with respect to the member 9. The periphery of the member l: is depressed at m and raised at a, the portions m and a being continuous with each other, and an integral partof the wall ofthe member k," and so forms aream for engaging the fingers e to deflectfthem radiallyin'ward to engage the rimor projectionj and thus support the shade or reflector R. This clamping movement of the fingers 0 results from the rotary movement of the member 7.; upon the member 9 in a counter clockwise direction,- as xviewed' in Fig. 2. At the end of thepbrtionm of the cam there is a more decided depression 0" serving as a stop to prevent the rotation of themember beyondthe position shown; In F 1g. 3 the parts. are shown in the position where the member is has been rotated upon the member 9 in a clockwise direction so as to allow the fingers c to spring om;-

wardly to release the shade or reflector R1 Rotatable upon the member 9 andsecured thereto by fi'ange'and groove engagement is" the upper cam member 79 surrounding the upper ends of the finger of thisupper member 7) is similar tothat-of the lower member is, being provided 'with cam surfaces in the same manner, so that by rotation of the member. 7') upon the member The, structure g the fingers are causedto engage thesocket;

The members g, Zr, and 7) are preferably made of brass, or other sheet metal, though .anylsuitablc material will srve and maybe formed by spinningior any other sl litable process and the cams formed by me -orzjl'n'y other suitable means; The 6 may be ofthe same material as'membcryg, but

may have secured upon them suitably shaped pieces of metal to' form a cam or wedge to accomplish the same. purpose.

YBythe foregoing construction a strong attachment is formed for supporting a shade orrefiector, particularly when of glass or other vitreous material in the manufacture of which irregularities in outer diameter of Because the fingers c are of sufficient strength and capable of suflicient radial movement, these irregularities do not prevent the shade or reflector being firmly gripped and held.

.While I have here shown one form of my invention, it is to be understood that my invention comprehends also other structures wherein cam or wedging action takes place upon suitable fingers to clamp the attachment to theshade or reflector member or to clamp the same to a socket or other support.

What I claim is: 1. In an attachment, the combination with a finger supporting member, of a finger separate therefrom and secured thereto and extending lengthwise of said supporting member within the same, and a finger actuating member supported upon and rotatable always in the same plane upon said finger supporting member said finger actuating member whenrotated upon said supporting memher engaging said finger to deflect the same.

2. In an attachment, the combination with a finger supporting member, of a separate finger extending lengthwise thereof within said member and secured thereon, a finger actuating member supported upon and rotatable always in the same lane upon said finger supporting member, and a cam carried by said finger actuating member for engaging" said finger to move the same into engaging position.

g. The combination with a lailnp socket, of a n er su ortin rin a soc (et engaging finge 'sup ib rted ithiii hnd by said finger supporting ring .and extending lengthwise thereof, a finger actuating ring having a lip therefrom and rotatable with respect thereto, and a camon said finger actuating member for engaging said finger beyond said finger supporting ring.

5. The combination with a lamp socket, of a finger supporting ring, a plurality of separate fingers secured to said finger supporting ring and extending lengthwise of said finger supporting ring, a shade or reflector, said fingers adapted to engage said lamp socket and said reflector at their opposite ends, and rotatable cam members supported by said finger supporting ring and movable with respect thereto always in the same lane for causing said fingers to engage sald socket and said shade orreflector.
