HOLDER FOR REFLECTORS Filed Dec. 8, 1928 ATTORNEYS Patented June 2, 1931 UNITED STATES NIELS LANG, OF LAKEWOOD, OHIO HOLDER FOR REFLECTORS Application led December 8, 1928. Serial No. 325,134.

This invention relates to an improved device in the art of lighting fixtures.

The obj ect of the present invention is to devise an improved form of holder by which a "reflector may be supported from the socket of an incandescent bulb.

More particularly, the present invention relates to an improved arrangement at the lower end of the holder whereby there is afforded an eflicient and convenient means for installing the same and at the same time, presenting a very neat appearance and without increasing the cost of manufacture.

Other objects will appear from the followl ing description and claims `when considered together with the accompanying drawings.

Fig. Vl is a side elevation of my improved device; Fig. 2 is a vertical sectional view of the same; and Fig. 3 shows my improved de- '20 vice in top plan view.

The lower end of the present improved holder is adapted to be attached to the reflector l for suspending the same from the socket 2 of an incandescent lamp. The reflector, socket, and bulb are shown only in skeleton form since the present invention relates exclusively to the improved form of holder.

This holder, as here illustrated, comprises 30 three duplicate parts 3, which may be formed as stampings and each-of which is provided with an annular grooved portion 4 extending about the lower endportion thereof for engagement with the rib 5 at the top of the reflector 1. The lower end portion of each stamping continues downwardly and sufficiently under the rib 5 to aii'ordY suspending engagement therewith. The extreme lower end portion of each stamping terminates in the rib or bead 6 under the rib 5, and at the same time affords a groove on the outer surface thereof to receive the endless coil spring 7 for engagement therein. When the three stampings are assembled together, the rib 5 of the reflector is effectively engaged by the inner complementarv grooves in the several stampings and the ribs 6 of all of the stampings extend in the same complementary manner. Thus, the coil spring 7 extends vabout 50 what virtually corresponds to a continuous groove upon the outer side of the rib 6. Each stamping is also providedwith an integral downwardly extending tongue 8 so as to prevent accidental displacement of the spring 7 from the groove prior to installation.

The upper end of each stamping is provided with a pair of radially extending ears 9 through which the screws 10 are adaptedto extendvfor drawing the same together about the lamp socket 2. The intermediate top end portions of the stampings are provided with the inwardly extending ears 11 which are adapted to engage the socket for firmly positioning the holder thereupon, above rib 2a.

In order to install the present holder, it is merely necessary to engage the lower end of the same over the upper end of the reflector so as to position the ribs 6 of the stampings under the rib 5 of the reflector. The coil spring 7 then maintains the parts in such position without adjustment or manipulation. At the same time, the coilspring 7 by virtue of its particular arrangement in the present construction, tends to draw the extreme lower end portions of the'several stampings inwardly and as a result, the upper end portions ofthe stampings are forced outwardly, thereby facilitating the positioning of the upper end of the holder about the socket 2 preparatory to clamping the same thereupon. This action is made possible by virtue of the fact that the coil spring 7 is lo- 'cated beneath the'bead 5 which serves as a fulcrum about which the several stampings are virtually pivoted upon contraction of the spring 7 in the manner vabove described. Then, with the holder attached to the upper end of the reflector, the upper end of the holder is then freely positioned about the socket 2 and is clamped in such position by tightening the screws 10. In order to remove the holder, the same can be accomplished by reversing the order of operation as just'now described. f

Thus, it will be seen that the groove which is Jformed upon the outer surface of the-rib 6 notV only affords a means of engagement under the rib 5 for effectively supporting the reflector, but serves also as a means for seat-l ing the coil spring 7i This two-fold function of the groove serves to simplify the construction and to present an extremely neat appearance. The particular manner of mounting the spring, with relation to the other parts, serves to maintain the upper end of the holder in open position until the screws 10 are tightened. Thus, the positioning of the hol-der about the socket is greatly facilitated. Furthermore, the degreeofengagement of the coil spring 7 about the lower part of the holder is uniform at all points and this manner of engagement involves no adjustments which are apt to become disengaged or to require attention. The endless coil spring automatically adapts itself to the position for effective engagement. Y

The -increased facility with which the present holderzmay be installed means a decided saving intime with the increased convenience. At the same time, the present form of holder presen-ts an extremely neat appear- It is to be understood that the present disclosure is merely for purposes of illustraktion and that there may be devised various modifications without departing from the spirit of the presentinvention.

This same holder may be employed in connection with a globe as well as a reflector, as will be readily understood by those who are skilled in the art.

What I claim is:

l. VA reflector holder comprising rigid means for effecting engagement of the one end thereof with a support, rigid means at the other end thereof for engaging a reflector, and means whereby engagement of the holder with the reflector will tend to render said other engaging means ineffectiveuniformly thereabout, thereby facilitating positioning of the holder preparatory to effecting engagement-of the holderv with a support.

f2., A reflector `holder comprising aconcentrically adjustable opening aty one end for engaging a support, means at the other end thereof for engaging a reflector and means whereby engagement of the holder'with the reflector will maintain the holder open at the Y said one Vend uniformlythroughout, thereby facilitating the engagement of the holder with the support. 1

3. A reflector holder comprising manually adjustable rigid means for effecting engagement of the one end there-of with a support, automatically adjustable rigid means atV the other end thereof for` engaging Aa reflector uniformly throughout, and means whereby engagement of the holder with the-reflector will tend to render said other engaging means ineffective, thereby facilitating positioning of the holder preparatory toV eeeting engagement of the holder witha support.

4. A reflector holder comprising means for effecting engagement of the one end thereof with a support, annular spring means: at

the other end thereof for engaging a reflector concentrically tliereabout, and means whereby engagement of the holder with the reflector will tend to render said other engaging means ineffective uniformly thereabout, thereby facilitating positioning of the holder preparatory to eifecting engagement ofthe-holder with a support.
