Claims.

`My invention relates to shade securing means. In certain types of reectors it has heretofore been the practice to provide each reflector with means permanently secured thereto for attaching the reiiector in position with respect to a lamp socket. As there are various types of lamp sockets, different forms of attaching means had to be provided for these reflectors in order to adapt them for the different types of sockets. As the attaching means were permanently secured to the reflectors, this necessitated that the distributor 01' dealer carry a line of reiiectors for each type of socket.

One of the objects of my invention is to provide a reflector supporting attachment which can be readily attached and detached with respect to the reflector so that by having a suitable supply of various types of these attachments on hand the dealer or distributor can t up a single liney of reflectors for use with any of the various types of sockets, thus enabling him to carry but a single line of reflectors, where heretoforeit had been necessary for him to carry a number of lines, one for each type of socket.

A further object is to provide such a construction in which a substantial portion of the reflector supporting attachment is located inside the neck of the reector.

A still further object is to provide such a construction which will be durable and efficient in use and inexpensive to manufacture.

Further objects will appear from the description and the appended claims.

In the drawings in which three forms of the invention are shown:

Figure 1 is a fragmentary side elevational view showing a reflector secured in position with respect to a porcelain socket;

Fig. 2 is a plan view of the attachment;

Fig. 3 is a section on line 3 3 of Fig. 2;

Fig. 4 is a perspective of one of the securing springs;

Fig. 5 is a side elevational View showing another form of attachment;

Fig. 6 is a plan view of the attachment of Fig. 5;

Fig. 7 is a section on line 7--7 of Fig. 6;

Fig. 8 is a side elevational View cf another form of attachment;

Fig. 9 is an axial section through the attachment of Fig. 8; and

Fig. 10 is a section on line 10-10 of Fig. 9.

Referring to the drawings in detail and rst to Figs. 1 to 4, inclusive, the construction shown therein comprises a porcelain socket 1 having an (Cl. 24U-128) outwardly extending annular flange 2y at its lower end, a reector 3 having an inwardly extending annular flange 4 at its upper end and a reflector supporting member 5 having a snap connection t with the inwardly extending 4flange 4 of-theL re- 60 flector and having a clamping connection with the porcelain socket. i The snap connection comprises a pairA of duplex leaf spring members 7 and 8 riveted'at- 9 to the inside of the annular collar ld'which can r65 be inserted down through the opening in the annular flange 4 of the reflector. This annular collar 10 is provided with four aperturesv ,1-1, one for each end of each of the duplex springs 5, thus enabling these latch-like ends to extend `through 7o the openings into latching engagement with the underside of thereectorflange 4. Theselatching ends are beveled off as'indicated in Figs. 1, 3, and 4, to facilitate their entry into the open ing in the reiiector flangethe slope being such that the latched ends are forced inwardly as the collar is inserted into the fiange opening, the latch members snapping out as soon' as their upper edges have'passed underneath the reflector flange. y, t 80 The distance to which the collar 10 can 'bef inserted into the ange opening'is limited by the engagement of the downwardly bumped portions 12 of the outwardly extending flange 13 `at, the upper end of the collar which-engage the upper face of the inwardly extending flange of the reflector. These downwardly bumped projections 12 provide a slightly yielding engagement with the ange of the reflector, the flange being en-w gaged on its lower side by the four spring latch4` 90 members 5 and being engaged on the upper surface by the downwardly bumped projections 12 of the collar ange.

The clamp for securing the attachment to theirc socket comprises a pair of clamping members 14` 95 riveted to the upwardly projecting ears 15 on the collar member 10 and having straps 16 punched inwardly for engagement above the annular supporting flange 2 on the socket. A pairyn of clamping screws 17 are provided for drawing 100 the ends of the clamping members toward each other to bring the straps rmly into engagement with the sides of the socket. In order to hold the attachment in proper relation with respect tom the refiector and prevent relative rotation there-L between, portions 18 of the outwardly extending flange are cut and struck downwardly so as to fit in suitably positioned notches 1,9 formed in the inwardly extending flange of the reector. With this construction, it will be seen that th' '-110 -14b on: the` reector .supportingattachment reflector supporting attachment can be readily attached to the reflector so that the attachments and reectors can be shipped unassembled to the distributors and dealers who can then fit up the reflectors as required with the desired type of socket attaching member.

Figs. 5, 6,v and'? show a reectorattachment for another type/of: socket in' which 'portions of the socket of the interior construction are held up by means of a threaded supporting ring '14a screwed inside of the threaded skirt portionla of the socket casing. In this form, the reflector supporting collar 10 is formed as an integral @part of the screw ring 14a which serves to support the socket interior. The collar. and spring latching construction is precisely the same as that shown in Figs. 1 to 4, inclusive. The screw ring 14a is provided with an inwardlyextendingflange at its upper end on which rests the shoulderfofv the socket interior.
