A conrormrio'n o'rl DELAWARE LIGHTING FIXTURE Application filed November 15, 1928. Serial No. 319,582. f

This invention relates to certain new and useful improvements in hghting fixtures and refers more particularly to a clip for cusl ioning and holding the reflectors at, their points ofconnection with the body of a lighting' fixture.

Reflectors for street lighting fixtures are usually stamped from sheet metal and have their lower or reflecting sidecoated with vitreous enamel-which is extremely hard and brittle. Due to the brittle nature of the enamel coating, ithas always beendilflcult to provide means for attaching thejreflectors to the lighting fixtures without chipping and cracking and object to provide an efiicient and simple cushioningmeans for protecting the reflector at its; point of connection with the fixture. j

Another object ofthis invention resides inthe provision of a simplified cushioning member for use in fastening reflectors to lighting fixtures which is formed of lead or other suitable soft material. I

A further object of this invention; resides in the provision of an improved cushioning device for' protecting reflectors at their point of connection with a lighting isinexpensive and which may plied at the: time of assembly. I

And a still further object ofwthis invention resides in the provision of an improved cushioning member for reflectors of lighting fixtures Whichincorpora-tes means for locking the securing means against; accidental detachment.

be readily ap- With the above and other objects in View which willappear as the description proceeds, my invention resides in the novel con-struction, combination and arrangement of-parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the preciseembodiment of the herein dis.- closed invention may be made as come Within the scope of the claims. V

In the accompanying, drawing,- I have illustrated one-complete exampleof. the physical embodiment of. my invention, constructed ac ording-to he best mo Iha e so ar d the present invention "has as an,

Figure 4 isa perspective View "of one of :the cushioning mem ers shown detached from'the reflector, 1 v I Referring now more-particularly to the accompanying drawing, the numeral 5 designates the body of a lighting fixture'which is usually formed of porcelain or thelike, having a, suspension member oreye 6 by which thedevice is suitably supported and being. recessed to receive a lampsocket and 1ts-ad ust1ng means, not shown. 1

. Numerous different methods of reflecting the light are used and in the presentinven lamp, not shown, is retion the light of the flected by a reflectonm'ember 7 ofsubstantially disc shaped andstamped from sheet metal. The under or reflecting side of the reflector is coated with a vitreous enamel to givefthe desired reflecting. surface; and to protect the enamel which is extremely hard and brittle, from cracking and chipping when I applied to the fixture this inventionprovides a new and novel cushioningmember 8 formed of a strip of soft metal, such aslead or thelike. r v

The cushioning members 8 are provided at each point of connection of the reflector ,with the body andareeach foldedat a medial 7 pointto form an upper leg 9 and; a lowerle'g 10, and in thepresent embodiment the legs 9 and 10 have their outer ends enlarged,- as at 11 and 12,- and apertured, as at'13f and 14;, re

metal adjacent the aperture 14: in the lower arm 1-0 is pressed upwardly in an annular head 15 and the aperture 1 3 inv the upper leg 9 ceive the annular bead. In use, the. cushr ioning membersare slipped-over the flanged periphery 146 of the centralopeni'ng; in. the

is of a size sufficient to reupwardly toengage their annular beads 15 in the adjacent openings 17 The annular beads 15 are of suflicient height to extend through the openings 17 and likewise through the apertures 13 in the upper arms 9 and thus completely protect the enameled surface of the reflector.

Attaching screws squared openings reflector 18 preferably having a head 19 pass through the aligned in the cushioning members and the to be threaded in metallic sleeves 2O cemented or otherwise secured in apertures 21 formed in the wall of the procelain housing or body 5 and to prevent the sharp edges 19 from digging into the soft metal of the cushioning members, washers 22 which are preferably formed of relatively thin metal to prevent localized pressure on the reflector are provided between the heads of the screws and the cushioning members. As lighting fixtures of this character are more or less subject to vibration in many different forms, means are provided for preventing retrograde turning of the screws 18 and the consequent dropping of the reflector, which consists of a lip or lug 23 on the extremeouter end of the lower arm 10 of each cushioning member which, after the screws have been drawn tight, is bent downwardly to engage the adjacent flat face of the head 19 of its screw.

From the foregoing description, taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an invention of the character described appertains that I provide a new and novel cushioning means for protecting the enameled surface of reflectors of lighting fixtures at their points of connection with V the fixture which means are extremely simple and inexpensive and which llkewise form locking members for preventing accidental r detachment of the holding screws of the reflector.

WhatI claim as my invention is:

1. The combination with a lighting fixture having a body member and a reflector, of means for connecting the reflector with the body member of the fixture, comprising a cushioning member'adapted to be engaged over one edge of the reflector, andsecuring means passing through aligned apertures in the reflector and cushioning member and engaged with the body of the fixture.

2. The combination with a lighting fixture having a'body member and a reflector, of means for connecting the reflector. with the body member of the fixture, comprising clips formed of relatively soft material adapted to be engaged over one edge of the reflector and having a part disposed on each side thereof, and securing means passed through aligned apertures in the reflector and clip and engaged with the body of the fixture.

3. In a lighting fixture having a body member and a reflector adapted to be connected therewith, a device for protecting the reflec tor at its points of connection with the body member, comprising a clip formed of suitably soft material bent medially to have a part disposed on each side of the reflector, screw means passed through aligned apertures in the reflector and the clip and threaded in the body, and means carried 'by the clip for preventing accidental turning of the screw.

1. A clip for protecting the enameled surface of reflectors of lighting fixtures at their points of connection therewith, comprising a member formed of suitably soft material folded at a medial point to provide a pair of arms apertured adjacent their outer ends, one of said arms having a portion struck therefrom to be engaged in an aperture formed in the reflector when the clip is assembled therewith.

5. The combination with a lighting fixture having a body member and a reflector adapted to be attached to the body member, the reflector having an aperture, of a cushioning clip formed of suitable soft material and folded medially to provide-a pair of arms, the arms being apertured adjacent their outer ends, an annular bead struck up from one of the arms adjacent its aperture which is received in the reflector aperture when the clip is assembled therewith, screw attaching means passed through the apertures in the clip and reflector and threaded in the body member, and a lip carried by the clip and engageable with the head of the screw attaching means to prevent accidental turning thereof.

6. The combination with a lighting fixture having a body and a reflector connectible therewith, of a cushioning member to protect the reflector at its point of connection with the body member said cushioning member having a part engageable with one edge of the reflector to hold the sameagainst movement with respect to the reflector, and securing means clamping the reflector to the body through the cushioning member.

7 The combination with a lighting fixture having a body member and a reflector connectible therewith, the reflector having an aperture, of a cushioning member having a part disposed on each side of the reflector with a part extended into the aperture to line the same and a part engaging one edge of the reflector to hold the cushioning member against turning about the axis of the aperture, and screw means passing through the aperture and threaded into the body memher to clamp the reflector to the body member through the cushioning member.
