To all whom it may concern:

Be it lmown that I, HENRY DOLIER, Jr., a citizen of the Un'ited'States, residing at Bridgeport, county of 'Fairfield, State of Connecticut, have invented an Improvement in Reflector Holders, of which the following is a specification. I

This invention has'for its object to :provide a reflector holder adapted for general use and especially adapted for use in connection with porcelain lampsockets. A further object of the invention is to provide a reflector holder which may be either permanently or detachably secured to the'lamp socket, which will hold the heaviest reflectors rig idly and securely, and which will permit the reflector to be removed without interference with the lamp socket. k

With these and other objects in view, I have devised the novel reflector holder which I will now describe,'referring' to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts 2- Figure 1 is an elevation showing my novel reflector holder in use;

Fig. 2 a section on the line 2'-2 in'Fig.

' 1, looking in the direction of the'arrows,

with the reflector removed; I

Fig. 3 an elevation corresponding with Fig. 1, showing the loc'king'members in the releasing position, and the reflector detached Fig. 4: an elevation on a reduced scale showing another mode of attaching the holder to a lamp socket, and I Fig. 5 is a detail 'viewi on an enlarged scale corresponding therewithl In Figs. 1, 2 and 3, 10 den'otesaone-part porcelain lamp socket, and 11 a shade or reflector. The neck of the reflector, or an extension by which it is carried, isprovided with a groove 12 which is engaged by the holder. The special construction of the socket is unimportant so far asthe present invention is concerned. It is suiiicientto say that the porcelain body ofthe socket is secured to a metallic cap 13 which in turn'is secured to atube 14: through which the electrical connections pass.

'My novel holder comprises'essentially a plurality of resilient locking members, in the present instance three, each formed from a'single piece of wire. The mid-length of the piece of wire 'is bent to form an arcshaped gripper 15*which is adapted to pass into the groovein' the neck of a reflector or extension and the curvature ofwhichcorresponds with the curvature of the neck at the baseof the groove. At'the endsf'of the gripper, the wire is bent outward, 2133.11 16, so as to clear theupp'er end 01": the neck, and is then bent upward and inward to form arms 17, the upper ends of the arms being bent inward at substantially right angles'and passed into holes 18 in the cap. A band 19 near the upper end of the porcelain body incloses the body and the arms tightly and retains the holder securely in place. The locking membersare of'course formed by automatic machinery and the wire is given a set which causes the looking members,.whenassembled, to normally spring outward "radially, the gripper's normally separating and springing out ward far enough to disengage them entirely from the-groove'in the neck, so' that in the normal or releasing position of the locking members, as in'Fig. 3, the neck of a reflector or extensionmay be freely'passe'd inward between the grippers 'or may be removed from between the grippers. As a means of securely retaining the locking members in the locking position,'I provide rings 20, each of which inclosesthe contiguous arms of two locking members. Theserings-when forced downward on'the arms, as in Fig. 1, act to draw the lower ends of thelocking members inward radiallyand cause the grippers to pass into the groove' in the neck and engage the base'oftlie groove firmly, thus locking fe'rs only in the means of attaching the holder to the lamp socket. The lower part with a groove 21 which receives the'parts of a clamp 22. The parts are formed to an '5 are shape to fit the groove closely and are provided at their ends with ears 23 threaded to receive set screws 24 by which the parts are drawn together and closed tightly into the groove to lock the holder to the socket. The locking members are made resilient and contiguous arms of two members are inclosed in rings, as before, which cause the locking members to grip or release a reflector. It will of course be obvious that four or even more locking members may be used, if preferred. I find, however, that three locking members work admirably in use.

Having thus described my invention, I claim:

1. A reflector holder adapted for attachment to a lamp socket and comprising a plurality ofindependent resilient locking members each formed from a single piece of wire, the mid-length of which is bent to form an arc-shaped gripper, the wire at the ends of the gripper being bent outward to clear a reflector member as set forth, and then up ward to form arms, means for attaching the independent ends of the arms in fixed posltion to a lamp socket and rings inclosing the contiguous arms of two locking members, upward or downward movement of the rings causing the grippers to assume the releasing or looking position.

2. The combination with a lamp socket and a reflector or extension having a grooved neck, of a holder comprising a plurality of independent resilient locking members, each consisting of an arc-shaped gripper and arms, means for securing the independent ends of the arms in fixed position to the lamp socket and rings engaging the contiguous arms of two locking members, said rings acting when pressed downward to cause the grippers to pass into the groove and lock the reflector in place.

8. The combination with a lamp socket member and a reflector member having a groove, of a holder for supporting the reflector member with respect to said lamp socket member comprising a plurality of separate and independent locking members each having an arcuate portion adapted to engage in said groove and arms extending longitudinally above and below said socket member, means for securing the upper ends of said arms in fixed relation with respect to said socket member, and members engaging neighboring arms of neighboring locking members and movable longitudinally for drawing said arcuate portions into said groove.

4. The combination with a lamp socket member and a reflector member, of a holder for supporting said reflector member with respect to said lamp socket member comprising a plurality of separate and inde pendent locking members each consisting of an integral piece having an arcuate engaging portion, upwardly extending arms at the ends of the arcuate portion, a cap secured to said socket member and having apertures receiving the inturned ends of said arms, and members engaging neighboring arms of neighboring locking members and movable longitudinally thereof for causing said arcuite portions to engage said reflector mem- 5. The combination with a lamp socket member and a reflector member, of a holder for supporting said reflector member with respect to said lamp socket member comprising a plurality of separate and independent locking members each consisting of an integral piece having an arcuate engaging portion, outwardly extending portions at the ends of said arcuate portion, upwardly extending arms at the ends of said outwardly extending portions, means securing the upper ends of said arms to said lamp socket member, and members engaging neighboring arms of neighboring locking members and movable longitudinally thereof for causing said arcuate portions to engage said reflector member.

6. The combination with a lamp socket member and a reflector member, of a holder for supporting said reflector member with respect to said lamp socket member comprisinga plurality of separate and independent resilient locking members, each comprising an arcuate portion, longitudinally extending arms at opposite ends of said arcuate portion, a cap secured to said lamp socket memher, the free ends of said arms secured by,

said cap, and members engaging and movable longitudinally of arms of neighboring locking members to bring said arcuate portions into engagement with said reflector member.

7. The combination with a lamp socket member and a reflector member, of a holder for supporting said reflector member with respect to said lamp socket member comprising a plurality of separate and independent resilient locking members, each comprising an arcuate portion, longitudinally extending arms at opposite ends of said arcuate portion, a cap secured to said lamp socket member, the free ends of said arms secured by said cap, members engaging and movable longitudinally of arms of neighboring locking members to bring said arcuate portions into engagement with said reflector member, and a circumferential band engaging said arms.

8. The combination with a porcelain lamp socket member, of a metallic cap to which said member is secured, a reflector member,

a holder for supporting said reflector member with respect to said lamp socket member comprising a plurality of separate and independent resilient members each comprising an arcuate portion, upwardly extending arms extending inwardly above said lamp socket member and held by said cap and members engaging and movable longitudinally of said arms of neighboring resilient members for causing said arcuate portions 10 to engage said reflector member.

In testimony whereof I affix my signature.
