REFLECTOR-SHADE.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed May 2, 1905. Serial No. 25 8,463.

To all whom, it inay' concern.-

Be it known that I, WILLIAM H. SPENCER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Reflector-Shades; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

The present invention has reference generally to improvements in that class of reflectors for incandescent electric lights, which reflectors are rovided with a centrally-disposed screw-t eaded collar for attachment of the shade of the reflector upon a screwthreaded fixture or bracket.

This invention has for its principal objects to provide a simple and cheaply-constructed reflector of the general character hereinafter set forth and, furthermore, to provide in connection with the shade of the refiectora novel and simple clamping or holding means for securing the screw-threaded collar which is to be screwed upon the fixture or bracket to or within a centrally-disposed opening in the shade of the reflector, the said clamping or holding means of the screw-threaded collar being of such a construction that the parts are intimately and securely united and cannot become disconnected or loosened when screwing the screw-collar upon the fiX- A further object of this invention is to provide a novel and positive means for immovably securing one or more screw-receiving sockets or devices to the shade to receive the screws by means of which the usual lightcluster is secured upon inner central ortion of the shade of the-reflector; and, fina ly, another object of this invention is to cover and entirely surround the marginal reinforcing bead or turnover of the reflector-shade with a layer of enamel or other suitable material, so as to provide the reflector-shade with a straight u per face at all points and prevent all possibi ity of water during rain and snow storms from lodging upon the shade to the detriment of the enamel and the shade proper.

My present invention consists, therefore, in the novel reflector-shade hereinafter set forth; and, furthermore, this invention consists in the various arrangements and combinations of the several devices and parts, as well as in the details of the construction of the same, all of which will be more fully described in the following specification and then finally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figures 1 and 2 are a top and bottom view, respectively, of a reflector-shade embodying the several improvements of my present invention; and Fig. 3 isa longitudinal vertical section, on an enlarged scale, said section being taken on line 3 3 in said Fig. l of the drawings. Fig. 4 is a sectional representa tion of a portion of the reflector-shade, showing an arrangement of o enings or holes for the central fiXture-attac 'ng ring and a pair of cluster screw-receiving sockets, the said ring and screw-receiving sockets also being shown in vertical section, but in their detached relation with the reflector-shade and about to be inserted in their assembled posi tions in the respective holes or openings in the reflector-shade. Fig. 5 is a similar sectional representation of the parts represented in said Fig. 4, but showing the fixture-ring and the cluster screw-receiving sockets in theinimmovably-fixed positions relative to the shade of the reflector. Fig. 6 is a detail vertical section of the marginal and beaded edge of the shade and the layers of porcelain or other similar material upon the upper and inner faces of the shade and about the bead to provide the shade upon its upper face with a straight and unobstructed surface for the water to run off from the said shade. Fig. 7 is a side view of a modified fixture-receiving ring; and Fig. 8 is a horizontal section ofthe same, said section being taken on line 8 8 in said Fig. 7 looking in the direction of the arrow :70 in said Fig. 7

The reflector-shade herein described is character were also provided with a central fixture-receiving ring and with cluster screwplane of the upper face of the shade, the

parts of course being enameled, as usual; but

when thus made the shade always had a marginal portion raised above the plane of the u per 'face of the shade, and the result was t at the water-from rain and snow invariably lodged against the raised part or shoulder. This had a deteriorating efl ect in that the water, due to .the elements and changes in the weather, caused the enamel in time to peel away, whereby the metal body of the shell becamerusted and was rendered unsi htly. Furthermore, in time the refle'c-.

torade thereby was rendered useless and had to be replaced. Reflector-shades of this receiving sockets; but the method and means -e'mployed for securing the said ring and screw-receivin sockets to the comparatively thin metal bo y of the shade was such. that an ineflicient and insecul'e'fastening. means was the result, and. especially with the fixture-receiving ring in screwing thesame too forcibly-upon the screw portion of the fixture or bracket, the soldered or otherwise-fastened ring'was easily dislod ed from its operative position upon the sha e or when not entirely dislodged was sufiiciently loosened to render; the device inoperative.

Referrin now to the several figures of the 1 drawings, t e reference character -1 indicates or body of the same.

the reflector-shade, and 2'is the metal shell portion the said shell or body is made with a receiving-opening 3 for the reception of. a fixture-receiving ring 4. The said shell or body 2 may also "be-provided with two or more other openings 5 for the rece tion of clusterscrew-receiying sockets 6. he said fixture-receiving ring 4 is provided with an internal screw-thread .7 and usually with av tightening or binding set-screw 8. The saidfixture-receivmg ring is also made with/a downwardly-extendin annular. flange 9, the lower marglnal edge 0 which is made thin or is chamfered upon its 'inner surface, as at 10 and as clearly shownin Fig. 4 of the draw-- ings. The u per outer surface of the said sockets 6 when employed are each provide with an internally-screwthreaded receiving portion 14 for the rece tion of the screwthreaded portions of t e usual screws by means of which the lamp-cluster is secured in its position u on the inner face of the re flector-shade. ach clustenscrew-receiving socket 6 is also made with a downwardly-e15- tending annular flange 15', the lower marg1- Inits upper central into the upward] ly as shown at-13. In a nal edge of which is made thin or is chain fered upon its'inner surface, as at 16. The

upper outer surface of the flange 1-5 and the lower portion of the main body of eachsocket 6 are made insuchf a manner that an annular shoulder 17 isformed, the lower surface of each shoulder 17 referably taperin wardly and inward y in the manner s own at 18 in Fig.4 of' the drawings.-

' Referrin now to Fi s. ings, it wil be seen .t atwhen the annular ,flange 9 of the fixture-receiving ring' 4 is inserted in the central receivmg-opemng 3 in the shell or body 2 of'the reflector-shade its undercut shoulder 11 will rest directly u on the upper surface portions of the said s ell or body 2' which'bound the said opening 3. In like manner when the vcluster screw-receiving sockets 6 are inserted in the res cctive openings 5 in the said shell or b0 y 2 each undercut shoulder 17 will rest directly upon the u per surface portions of the said shell or bo y 2 which boundthe said openings 5. After the said r 4 and sockets 6 have thus been arrange the chamfered marginal flanges 9 and 15 of the ring 4 and sockets .6, respectively, are u set a amst the 4and 5 of the draw under surface portions of t e sai shell or body 2in the manner illustrated in Fig. 5 of 1 the drawin s. From an inspection of said Fig. 5 it mi 1 be seen that the upsetting and closing down of the saidflanges 9 and v 1.5 against theunder-or inner surfaceportions' o the shell or-body 2 which bound lJhBVEL- P rious openings 3 and 5 draws the said bound- IOO' ing portions of the shell or body 2 upwardly I parts of the 'shoul ers 1'1 and17 offthe ring 4 and inwardly .tapering and sockets 6, respectively. In this manner .the said ring 4 and sockets 6 are securely fastened to the metal body or shell of the reflector-shade agains'tdisplacement, as will be clearly evident. Furthermore, this means and method of connecting the rin 4 and sockets 6 to'the shell or body2 provi' es water-tight connections at these points, as

will be clearly seen from an ins cation of Figs. 3 and 5. 'Referrin now to. 3-and '6 of the drawings, it wi 1 be seen t at said shell or body 2 is made'with an annular and downwardly-curved portion 19 and with a turned-over edge portion 20, terminating in Thisv edge 21 is pracean annular edge 21. tically in the same plane of the main shell or body 2, the annular head which is formed by these parts being slightly below the plane of the main shell or be y 2.

A coating or layer 23 of porcelain, enamel, or the like of one color, usually green, is placed upon the: upper and outer face of the shell or body 2,'-sa1 '12 5 layer preferably e'xtend- 1 .ing around the marginal head of the said f shell or 'body 2 and sli htly upon the inner -marginal edge portion 0 the-shell or body, as

at 24,- the remaining surface of the inner face 1 0 seaeso oi the said shell or body 2 being provided with layer 25 of white enamel or other similar material. In this manner the upper layer 23 provides a perfectly smooth and unobstructed surface for any water to run off therefrom, and a reflector-shade which is perfectly waterproof is the result.

1 am aware that some changes may be made in the arrangements and combinations of the parts, as well as in the details of the construction of the same, without departing i from the scope of this invention. Hence I do not limit my invention to the exact arrangements and combinations of the parts as described in the foregoing specification and as illustrated in the accompanying drawings, nor do I confine myself to the exact details of the construction of the said parts.

Having thus described my invention, what I claim is 1. In a reflector-shade, a metal shell or body formed with an opening bounded by an upwardly-extending marginal edge, and a receiving-fixture in said opening, said fixture having an internally-screw-threaded receiving portion and bein provided with an annularly-extending groove corresponding to and in which said upwardly-extending marginal edge is arranged, said fixture being pro-- vided below said groove with an outwardlyu or other layer upon the upper surface of said shell and around the said upwardly-bent marginal edge, the upper and outer face of the said layer being perfectly straight to prevent a collection of water upon the shade, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 26th day of April, 1905.

WILLIAM H. SlBENCER.
