My invention relates to electric lightingfixtures und particularly to a ineens Jfor intensifying the light in a. desired direction.

,ln Standard types of electric lightingh lixtures 03": the well-corrieri or hanging variety, it is necessary that one use relatively l" h wattage bulbs in order to obtain the requi Y downward illumination for reading or other purposes. The reoson for this is that innecessary einount ot light is dispers Cl ceY ward. The modern trend et interior decorotion is toward solitligjhting of the wells und ceilings through the inediuni oli `low wuttege bulbs or ornmnentel floor or telole` linups, either o? which ureconducive to eye when used 'for rondine; iurposcs. lilith respect to the wall or'door ninps, their 'ort' effect is spoiled when bulbs of suliciein wettegge 'for residingpurposes ure applied., and re- `tlectoiscunnot be used with such lonips witl out detructing 'troni the appearance thereof.

Brietly summarized, the present light ingl xtures require excessively high wattage bulbs for reading purposes, the use ot which produces glaring' ceiling' and well illuminetion and inertistic effects in iioor indie-,ole loinps,-all ot this being` contra to the present day theory of interior d Ycorution which uelnzinds soft ceiling und woll illumination.

Furthermore, the use of high wattage bulbs is expensive in current consumption.

It is, therefore, the primary object of niy invention to overcome the objections noted und to provide ineens whereby :i low wetten-e bulb nitty be availed of to preserve the sott toned illumination of ceilings and walls, but which will at the saine tiine produce the bri glit, concentrated light necessary for reeding,- Aund kindred purposes.

/lnothor object of the invention is the provision ot en appliance which is capable oi upplicution to standard types of lighting` tire tures without changing; the relative positions fie ornamental shades thereof, without deli-acting 'from their attractiveness.

A further and more limited object et the invention is to furnish en appliance for the purpose speciiied which involves un iinprovec e1;- tensible fixture plug having` s bulb receiving; socket and reflector associated therewith, the

` ull views,

4ler in ober 8 is secured to the screw plus P extensibility 01"' the plug permitting its re tlector to he located in e; predetermined position with respect to various kinds of orne.- inental lump shades.

The foregoing' and other objects of the in. 55 vention ure attained by ineens of s novel coinbination end arrangement of parts to be hereinafter described und claimed, and in order that the same may be better understood, retcrence is hed to the accompanying drewin forming u port of this specification. drawings illustre-.te wl'iut l now regard preferred embodiment of the invention is to be understood thatvurious chung modifications may be inode ther ...t a departure from the'spirit and scope or the subject matter clciined. i

In the drawings, wherein the seine referencechsructers designate the saune ports in Figure l is u. longitudinal sectional view et Y the up iliunce in association with u lmnp iii;n ture:

Figure 2 is e sectional view on the i ot Figure l lookingI in the direction o.

Figure 3 is e view sinniler Figure but lookingr in the opposite direction;

Figure l is group perspective view of' the elements of the extensible plug,` included '30 the invention; and Y y Figure 5 isn perspective view of the reticotor supporting` element.

Referring specifically to the drawings particularly to Figure l, itis notedthut e ventionul lmnp linture shown includ lmnp soclet l carrying;` u shade S. ln cu ing out the invention 'ie plugged end 2 of the extensible socket ine-inl is screwed into the lmnp 4rlirture socliet l, thc 90 extensible socket ineinbcr coinprehendir t billar telescoping' sections 8 und The n u :j .Jn en inwardly crnnped ond flange 3a cngeg the beveled circumferential shoulder 2 ot plug to thereby hold the plug end against u supperting` flange 3b carried inwardly 'of the tend through closed longitudinal slots 4 in the section or member 3. Thus the sections 3 and 5 of the socket are extensibly connected and may be bound in a predetermined set position by tighting of screws 7.

An insulating lining 8 within the extensible socket section 5 separates the porcelain contact carrying base 9 and its associated lamp'receiving socket 1() from the wall of socket section 5, it being understood the contact carrying base is frictionally held in place within said section.

Figures 1 and 4 clearly show that connection is made between the contact carrying base 9 and its lamp socket 10 by means of' a U- shaped stamping 12 screwed to the base as at 12 and engaging inturned flange portions 10'* of the socket 10.

The end contact point of the lamp plug 11 bears against a center contact piece c, secured to the base 9 by a screw b which also secures an L-shaped conductor 14 thereto, the latter having an upstanding arm 14a housed in one of the two side grooves 13 of base member 9. The other groove 13 receives the upstanding arm 12b of the U-shaped stamping 12, as shown. Lamp socket 10 is electrically connected to the plug end 2 of extensible socket section 3 by the flexible wires W secured as at 15 to elements 14, 14 and 12, 12".

The lower end of the extensible plug section 5 is screw threaded as indicated at 5a to receive the internally threaded annular ring 16 which is formed with diverging arm 17 having at their ends transversely disposed reflector supporting portions 18 of arcual form as best shown in Figure 5.

Referring to Figure 1, the reflector 19 is depicted in operative position and supported by the ring arms 17. Inasmuch as arms 17 are divergent, the edges of the central opening 19 of the reflector are spaced from the lamp bulb 11 and light is permitted to pass upwardly through the space 20 so produced to illuminate the ornamental shade S and cast a soft illuminating glow upon the walls and ceiling of the room. The reflector 19 concentrates the major portion of the light rays downwardly and by reason of this a relatively low wattage lamp will furnish just as strong a ra-ding light as would a high wattage lamp without the reector. Also the objectional brilliant illumination of the walls and ceiling is obviated.

It is believed to be obvious from the drawings that the extensibility of the socket 3, 5 enables the reflector to be adjusted to any desired position to suit the particular form of the ornamental lamp shade S. With shades of large diameter the reflector 19 may be positioned within the confines of the shade, this being manifest from an inspection of the drawings.

The reflector 19 may be made of different materials and shapes to harmonize with the various kinds of lamp shades.

Having thus described my invention, what I cla-im as new and desire to secure by Letters Patent is 1. The combination with the bulb receiving socket of a lamp fixture, of an extensible plug having one end inserted in said socket and having a bulb receivin socket at the other end, a reflector carried y said plug and adjustable therewith, a shade supported by and above said reflector and movable therewith, whereby said extensible plug is substantially enclosed by the shade and reflector.

2. The combination with the bulb receiving socket of a lamp fixture, of an extensible plug having one end inserted in said socket and having a bulb receiving socket at the other end, a reflector carried by said plug and adjustable therewith, a bell-shaped shade resting on said reflector and enclosing said socket and extensible plug and movable therewith.

3. The combination with the bulb receiving socket of alamp fixture, of an extensible plug having one end inserted in said socket and having a bulb receiving socket at the other end, a reflector having a central opening and being supported by an open support depending from said plug, said open support extending through the reflector, said reflector being adjustable with said plug, a translucent shade supported by and above said reflector and movable therewith, whereby said extensible plug is substantially enclosed by the shade and reflector.

4. The combination with a bulb receiving socket of a lamp fixture, of a plug having one end inserted in said socket and having a bulb receiving socket at its other end, said plug bcing adjustable in the manner to move its receiving socket toward and from its opposite end, a reflector mounted on the sockcted end of said plug and adjustable therewith, a shade mounted upon the upper surface of the reflector and movable with the same said shade enclosing said socket and extensible plug.

In testimony whereof I affix my signature.

CORNELIUS MAASHANT.
