unit for floor lamps, table lamps and various other kinds ot' fixtures where pull chain sock? ets have generally been previously employed, The object of the present invention is to provide a single unit two way socket which will eliminate and render unnecessary much ot' the wiring and the addition of pull chain sockets which have heretofore been necessary. l l
lA further obj ect of the invention is to provide a two way` socket unit of this character equipped with means for enabling it to be readily mounted inposition on the standard of a Vlamp or analogousportion ot other lixtures and' provided also with means for clamping a lamp `shade in position.
Another object of the yinvention is to equip the two lway socket unit with an interiorly arranged switch mechanism having means l0- cated eXteriorly of the lamp shade at the top thereoic for operating the switchV lVith these and other objects in view the invention consists in the construction Vand4 novel combination and arrangement of parts hereinafter fully described and illustrated in the accompanying drawings and pointed out in the claims lieretojappended, it beingl understood that various. changes in the form7 proportion and minor details of construct-ion within the scope of the claims may beresorted to without departing from the spirit or sacrificing any of the advantages of the' invention.

l In the accompan ingdrawings l illustrated the pre erred embodimentof the invention, the two way socket unit is provided with an insulating body l, constructed of molded bakelite or other suitable insulating material and consisting of an approximately cylindrical upper portion and downwardly di'vergingintegral sockets 2 and having at the bottom'a central'depending neck 3. v'I'hedepending bushing receive the upper end of 'a inetal vtube (if or other portion of a lamp or iixture. The metal tube '6 which Vforms a. support for the 'two way socket unitalso provides-a conduit for the wires fr' and 8 whichlare connected with and controlled the `switch mechanism hereinafter described. The threaded bushing is preferably embedded in 'the insulatedbody during the molding off the latter and in practice the twoway socket unit will be supplied to the trade vwithout the conducting wires as will be readily understood. The conducting wires,'the 'metal tube 6, and the lamp shade (9 being shown in the drawings for the purpose of illustrating the application of they invention 'to a floor or similar lamp but the twoway socket unit may ybe Nemployed for various kinds of fixtures and n'ilay be readily connected Athereto as will be readily understood. The hollow cylindrical upper portion, of the insulating body houses the switch mechanism hereinafter described and is provided at opposite sides with vertical ribs 10, forming seats for and supporting the upper transverse bar l1 which torins'tlie upper bearing for a operating shaft 1 2. The'upper transverse bar-w'vhich extends across ythe body l at the top thereofis rigidly secured in position upon the said ribs by screws engage threaded apertures `112.1; `in .the upper ends of the vertical supporting ribs of the insubtilis bedr The 111511.81' edge ef the body is cylindrical and horizontal and the supporting barfll which is located adjacentto ,the
upper edge ,of the body,- is .provided with 4al cent-ral exterioijly threaded sleeve l5 which.
forms the herring` for the-rapper por-tien of" the switch Operatie Shaft 112 eed which is also adapted ltoreceive ashade demping in which is neck has mounted yin it a metallic which is interiorly threaded at 5toV 16. The shade clampin disk 16 is provided with a ccntral'threadet opening 17 and it screws on the exteriorly threaded sleeve 15 and is adapted to clamp the lamp shade 9 betweenit and the ripper Vedge of the insulating body. The shade clamping disk is preferably of the same diameter as the upper `end of the body and it forms a cap or closure for the same. The clamping disk 16 is provided iny its upper face with a central circular recess 'Y 18 which is of a diameter to receive the switch 'operating button 19 having embedded in its lower face ya threaded sleeve 2O for engaging the upper threaded end 21 of the switch operatingshaft 12. The button is preferably recessed at its lower face as shown to provide a peripheral flange 22 which preferably extends into the recess of the vclamping disk but the switch operating button may beY arranged in spaced relation with the upper face of the disk as will'be readily understood. YWhen the button issecured on the upper -end of the switch operating shaft it is adapted to be turned to rotate the shaftffor operating the switch as hereinafter fully described.
The switch operating shaft 12 has an intermediatesquared portion 23 for the reception of a rotary switch member 24 and has round upper and lower portions 25 and 26 which are journaled respectively inthe upper transverse bar 11 and in a center bearing opening 27 of a stationary switch member 28. The stationarykswitch. member 28 consists of a transverse bar having a central circular enlarged portion provided with curved ratchet teeth 29 which are approximately triangular and which are adapted to be engaged by blades 30 of the rotary switch member'. The ratchet teeth 29 are .preferably four in number and two opposite teeth are providedwith stationary contacts 31 and 32 consisting of plates or pieces of conducting material hav-f ing attached portions which are secured to the end portions of the stationary switch member by screws 33 and 34. The screw 33 constitutes a binding screw'for securing the wire 7 to the stationary contact 31 of the switch.
The other screw 34 secures the stationary switch member to one of a pair of transverse conductor bai-S35 and 36. The rotary switch member 24 consists of a'central circular hub having a square opening to tit the squared portion of the shaft'and provided at its, pe-y riphery with the'vswitch blades30 which are curved "and arranged at a slight inclination as shown to fit the ratchet teeth of the stationary switch member. The ratchet teeth extend upwardly from the stationary.,
switch member and present' yinclinedfaces to the switch blades and vertical edges` whichform stops for `preventing retrograde movement of the rotary switch member. The'hub may consist'of a metallic disk havingthe' .integral blades asv shown, and upper and lower rings or disks 37 and 38secured` gagement with thestation ary switch member by means of a coiled spring 40 arranged on the lower portion of the switch operating shaft. and interposed between the upper transverse barand the rotary switch member. The upper end of the spring is arranged within lugs 41 rigid with and projecting downwardly from thel upper transverse supporting bar. When the switch operating shaft 'is rotated the blades are carried over the teeth of the stationary switch member and are car ried into electrical contact with the stationary contacts and out of contact with the same to close or breakthe circuit as desired.
The conductor bar 35 which is constructed yof suitable material extends across theubody bar 36 has inclined upwardly extending terminalI portions 46 which are connected by suitable fastening devices 47 with the flanges 48 of screw shell contacts 49. The lower conductor bar is centrally connected with the lower end 50 of an upwardly extending conductor bar 51; which is provided at its upper end 52 with a horizontally disposed port-ion carrying a binding screw 53 for securing the wire 8 tothe conductor bar 51. The conductor bars connect the center and shell contacts of the sockets and the conductor bar 35 is provided at its end 43 with a terminal portion 54 to which the stationary switch member issecured bythe screw which secures one of the stationary switch contacts to the stationary switch member. The stationary switch member is provided at the opposite end from that which is attached to the conductor bar, with a depending portion 55 which rests upon the conductor bar 35 and supportsthat end of the stationary switch member. lVhile the socket unit'illust-ratedin the accompanyying drawings is shownprovided with two opposite sockets yet it will be readily understood that the number ofthe sockets may be varied as will be readily understood.
