Application filed September 2, 1922. Serial No. 585,962.

To all whom it may concern:

Be it known that I, WILLIAM CLINE, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Reflectors, of which the following is a specification.

My invention relates to reflectors particularly suited for use on electric bulbs but also applicable to other lamps.

The reflector has a cone-shaped fluted or scalloped body with a center provided with flexible fingers adapted to grip around a bulb or lamp fixture and arranged in such a manner that it may be adjusted to lamps and bulbs of larger or smaller diameter.

In connection with headlights for automo biles, these reflectors have been found very useful.

One embodiment of the invention is illustrated in the accompanying drawing, and

Fig. 1 represents a perspective view of the reflector Fig. 2 is a vertical section thereof, and

Fig. 3 is a top plan view of the reflector adapted to receive several electric bulbs.

The body portion of the reflector, see Fi gs. 1 and 2, is cone shaped and preferably stamped out of thin sheet metal so as to form a plurality of radial flutes 9 around the entire body portion. The central part of the reflector is bent to form a cylindrical portion ll which is slit open in a plurality of places as at 12. The slit portions form gripping members 13 terminating with tapering fingers 14, which are bent inwardly at approximately a 45 degree angle as regards the cylindrical portion 11.

It is evident, that by providing these fingers, the reflectors will fit bulbs of diflerent diameter, as the fingers may be bent in or out as is necessary to get a hold upon the bulb or lamp fixture.

In Fig. 3 is shown a reflector which has also a cone shaped body portion 15 provided with radial flutes 16 as before. The central portion 17, however, is flat and furnished with a plurality of apertures 18. Each of these apertures have fingers 19 of the same shape as described in connection with Figs. 1 and 2, that is to say, a lower portion attached to the flat center 17 is cylindrical, while the ends are bent inwardly and tapering.

The best way to produce these fingers is as shown at 20 in Fig. 3, that is to say, a small aperture 21 is first stamped out of the flat center 17 from which aperture radial slits are made as at 22. The fingers thus formed are bent upwardly to form a cylinder and then inwardly to provide tapering ends corresponding to the fingers 14: in Fig. 2.

It has been found that the best material to be used for these reflectors, in order to provide a good reflecting surface combined with lightness of construction, is 18% of German silver and the remainder ordinary commercial brass.

It is evident that the reflector can be made in any size and may be provided with gripping flngers for one or any number of electric bulbs.

Instead of sheet metal for the reflector any other suitable material such as pressed fiber could be used with a glazed or painted reflecting surface on the inside of the flutes.

Having thus described the invention, what is claimed as new is:

A reflector produced from flat sheet metal to form, by bending, a fluted cone-shaped body and a center portion integral therewith, all of uniform thickness, said center portion being slit radially to provide, without stretching the metal, a plurality of tapering, gripping members bent upwardly parallel to the axis of the body and terminating with inwardly bent tapered fingers adapted to engage the exterior surface of a bulb.

In testimony whereof I aflix my signature.
