Specification of Letters Patent.

Patented May 30*, 1916.

Application filed May 10, 1915. Serial No. 26,927.

To all whom it may concern:

Be it known that I, ARTHUR/E. WIEDEN- nonrr, a citizen of the United States, resid ing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lamp-Shade Holders, of which the following is a specification.

My invention relates to means for supporting shades upon lamps and has particular reference to the mounting of shades on electric lamp sockets of the well known and practically universal type which has an interiorly threaded socket, into which the socket piece of the incandescent bulb or globe is screwed, and an exterior bead, projection or rib which supports the various forms of shade holders. A very common form of shade holder comprises a pair of rings connected by webs or spokes, the one, the smaller ring, being an open one withends bent out to form lugs engaged by a screw that contracts the ring upon the socket, while the other ring is provided with screws which enga e the curved rim of the shade. Among the higher art shade holders are found the socalled bell sockets which are considerably more expensive than the more prevalent types.

The general object of the present invention is to provide the more artistic, substantial, and more firmly mounted socket with the various advantages ascribed to it, at substantially the same cost of manufacture as I the cost of the cheaper and less desirable grades and forms.

Another object of the invention is to provide a construction which simplifies the operation of mounting the shade holder on the lamp socket.

With these and such other objects and advantages as the subjoined description will -which engage the rolled rim 11 of the disclose, in view, the invention consists in the novel construction of shade holder, its

combination with a lamp socket, and arrangement of parts, all as hereinafter described in detail, illustrated in the accompanying drawings and incorporated in the appended claims. Y In the drawing Figure 1 1s a perspective view of a conventional lamp, socket, a section of the usual pipe or tube protecting the wire-cord where it enters the socket, and my improved shade holder mounted on said socket. Fig. 2 is a longitudinal section lamp bulb, the latter not being shown.

through a socket of the type shown in Fig. 1, and a section of a broken away portion of a shade supported by the present improvement. Fig. 8 is a bottom plan view of Fig. 1. Fig. 4 is similar to Fig. 2 with the on ception that it illustrates the form of socket in which the switch key is on the socket instead of at some point removed from the socket, and Fig. 4: also shows the socket and shade holder separated, the dotted lines showing the position of the holder on the lamp socket.

In the several views 2 and 3 indicate, respectively, an ordinary lamp socket without a'key, and a lamp socket with a key each of which has interior threads 4 that engage the threaded socket piece of the ordinary electric On the different forms of this type of socket the socket is provided with a head 5 011 which the usual shade holder is suspended. The remaining details of this type of lamp socket are so well known to those skilled in the art, that they are recognizable at a glance where they appear in the several views of the drawing, and as they form no part of the present invention need not be described in detail in this connection.

In Fig. 4 the switch key 6- is shown together with its mechanism for the purpose of illustrating its position relative to my improved shade holder, which, artistically considered, is substantially a part of the lamp socket itself, an improvement in appearance thereupon, and a graceful merger of the socket into the shade -7. The shade holder does not reach the stem of the key and therefore requires no appearancemarring slot therein for the key-stem, chain, or other device for operating asocket switch.

With the exception of the three screws-- 8, 9 and 10-of the common shade-holders shade, the shade-holder embodying the present invention as exemplified in the several dividual spring members 18, 19 and 20 in 'Which are formed a channel or curved groove 21 which is engaged with the bead 5 by snap engagement. As shown perhaps best, in Fig. 4 the lowerend of the collar 14 slips over the lower end of the socket '2 or 3 until the bead5slips into the channel '21, formed by spinning or stamping a head on the socket 14 in the same way as the bead 5 is formed. The conventional socket 2 or 3 has its lower portion reduced to'form -a shoulder 22 which serves to limit the upward movement of the part of the ordinary shade holder which engages the socket. In other words, the shoulder 22 and the bead 5 cooperate to limit movement on the socket of thexsocketengaging portion of the usual shade-holder. The socket 14 is therefore provided with an enlarged upper portion 23 which provides it with a shoulder 24 that engages the shoulder 22 to limit the upward movement of the shade-holder, though this stop is' not essential to the operativeness of the present improvement, the bead 5 and groove 21 engagement providing limitation of movement both-upward and downward.

It will be noticed from'the foregoing description "that the strength of the socket is practically the maximum that can "be pro- "vided; that 'theusual opening or openings between the band 12 and the space thereabove is closed by a holder-strengthening part pleasing to-the eye which, substantially, at all points ofits circumference rests on the band 12'directly upon the body of 'theso'cket,

V fthe part 13 being an integral part of the band 12 and continuous therewith.

Although the holder is ornamentalyfirmly held and substantial its construction .does

-notinvolve the adjustment of'th'e wires 27 and 28, a common difliculty with the more ornamental and expensive "bell 'type for holders embodying such features as compariative unbreakability and a firmer seating or mounting than can be obtained in skeleton holders." It is substantially a complete cover for a socket cover, the uncovered part ebe'lowthe rim 25 of the usual cap'being an {ornamental channel '26 where every socket j lower end 'of the thus limited socket=to slide 'UVBIf3tl16 bead "5 for the -purpose of removing *the holder. Thegrooved portionengaging both Pside's of the bead is, however, preferred except' as to cost. 7 r

' The outer parts of the' bodies '2 and 3,

I 7 whichlform the shell for the usual interior porcelain insulation, switch, and innershell with "the threads 4 thereonyare known as the socket cover. The bead 5 is formed on this socket cover of the lamp socket.

Applicants inner part 14 is a complete socket, or inwardly turned collar formed of a part of the outer shell or shade holding portion, instead of merely a series of tongues which extend from the top of the outer shell down to the lamp socket bead 5. Only that portion of applicants inner socket, band or collar, which is to engage the lamp socket bead :5 is made flexible or expansibl'e, thereby causing the unsplit or continuous portion of the inner collar, or socket to act as a substantially inflexible support for the lower @tongue portions, making :the latter shorter or firmer in their grip, or making it unnecessary to weakenin-gly extend the tongues to the outer shell or shade holder portion. It also obviates the necessity of breaking the continuity and symmetry of the outer bell-shaped shell by forming lamp socket engaging tongues thereupon :or therefrom.

I claim as any invention 1. The combination with a socket cover having .a bead rthereon, of a shade holder having an inwardly turned collar thereon with a split lower -:end or edge which engages said bead.

2. Theicombin'ation with a lampsocket, of a shade holder having therewithm a-turned down collar the lower endoredge of which is split and forms a clamping portion of said collar, said collar donning a :lamp socket engaging socket.

3. The combinationwith a lamp socket, 101 a shade holder trom the upper edge of "which ldepe gis a socket in the form of a band or collar, said band or collar having its loweredges split to 'form a split collar portion, the upper portion of said-collar.being an unbroken band or socket portion.

4. The combination with a lamp socket, of a shade holder'consisting of an outer bellshaped shell provided with means to .removably support a shade, and an inner shell which forms asooketadapted togrip a lamp socket, said inner shell having an inexpensible upper end and an expanslble lower end both within the outer shell.

5. The combination with a lamp socket, of ashade holder-consisting'of a continuous or unbrokenouterfbell-shapedshell provided with means for supporting a shade, and of an inneridepending collar or shell with .flexible tongues on its lower end.

6. The combination with a lamp socket having a bead thereupon, of a shade holder -having an outer shade holding portion and an inner turndown collar portion having spring tongues on its lower end within said shade holding portion, .which engage said bead.

7. The combination with alamp socket, of ashade sholder having therewithin a collar depending from its upper end, the lower end of said collar having vertical slits therein forming spring tongues which clamp upon said lamp socket.

8. The combination with a lamp socket, of a shade holder which supports from its upper end a depending spun collar the upper end of which is larger than its lower end and expansively unyielding and the lower end of which is split to form an expansible and contractible gripping portion to engage said lamp socket.

9. The combination with a lamp socket having an exterior bead, of a shade holder having therewithin a turn down collar which forms a lamp-socket engaging-socket, the latter being contracted gradually downward and having vertical slits in its lower end to permit said lower end to expand and pass gveg said bead and to be supported by said ea i 10. The combination with a lamp socket having a bead thereon, of a shade holder having a spun, downwardly projecting and contracting inner collar, the lower portion or end of said collar being a split ring adapt-- ed to pass over and rest upon said bead.

11. The combination with a lamp socket, of a shade -holder having an inturned depending collar the upper portion of which is integral and the lower portion split, both said portions being within the outer body portion of.said holder.

12. The combination with a lamp socket having a bead thereupon, of a shade holder and holder socket, the shade holder portion being in the form of a bell, and the holder socket being in the form of a turned down inner collar having tongues on its lower end Wltllt channels or grooves which fit onto said bea In testimony whereof I have hereunto signed my name.
