and State of parts hereinafter de-v Fig. 8 is a' 1 ets as are provided with ascrew-shell to receive the screw-threaded base of the lamp.

- Among the objects of the invention are to to-facilitate the assembling gether in the process of manufacture and use.

Referring to the drawings wherein the invention is illustrated in its preferred form, 1, represents the insulating base, and, 2,411?) screw-shell, which for certain purposes of the invention may be of any desired form, as for example, that shown and de-' scribed in U. S. Letters Patent No. 743,207, granted to us November 8, 1903, to which patent reference may be had for a more complete understanding of the present invention. The screw-shell is adapted to .form one of the contact members whereby the circuit is formed through the lamp inserted in the socket.

The central contact-member, 3, projects through a cutaway portion, 4, of the screwshell interiorly thereof being mounted upon the ihsulating base in the manner shown in saidprior patent, or in any other known planner.- Opposite the cut-away portion of the screw-shell the shell wall is slitted transversely and a portion thereof introverted on the outer side of the slit, as shown at 6.

The disk, 7, of'mica, or other insulating material, is inserted within the inner end of the screw-shell and is retained in position by the abutting engagement of its outer side tion, 6,-of the shell. The introverted tion, 6, of theshell is inclined inwardly to? -ward the slit whereby-its cut edge is formed, forming an incline over which the curved edge of the mica disk isadapted to ride easily as, the disk is forced inwardly into position, the disk yielding or. springing suflicieritly to ermit it to do this. As soon as the edge 0 the disk has-passed the cut edge of the introverted portion, 6, the disk snapsinto position resuming its full circular .hape opposite said introverted portion. The edge of the disk, 7, is notched as shown at, 8, to receive the shank of the central con-- tact-member.

In assembling various parts mounted thereon it is necessary to secure perfect. alinement of screw-apervvith the overlying central contact-member, I and the cut edge of the introverted porthe insulating base and the simplify and improve the construction and f of the parts tov mg pro ections, her adapted to rest upon said end of the base,

tures formed in said base and the parts mounted upon the inner end thereof, such as the introverted end-flange, 9, on the screwshell and the horseshoe-shaped clampingplate, 10, adapted to receive the ends of the connecting screws, and to clamp said end flange of the shell upon the end of the insulating base. I the parts with the screw holes so alined, the end of the base is shown provided with depressions, 11, adapted to receive correspond- 27, on the conductive-memthe arrangement being such that when said projections are seated in said depressions the screw-holes, 30, of the assembled parts will be in alinement. As shown, the flanged end of the screwupon the inner end of the'base shell rests and the projections are formed thereon by displacing portions of'the end-wall or flange compressible and is also correspond 7 provided with v sleeve, 12,

'ruptly at its of the shell outwardly at 29- forming on one side thereof said projections and on the other side corresponding depressions. The clamping-plate 10 may in like manner be projections adapted to enter the depressions-so formed in the end-flange of the screw-shell to cause alinement of the screw-apertures in all-the connected parts, as shown in Figs. 4. and 5, saidprojections being formed by indentations 31.

Thebase and parts mounted thereon are inclosed within the casing comprising a and a cap, 13, adaptedto telescopically receive the inner end of said sleeve. The inner end of the sleeve is provided with a slot, 14, whereby it is rendered provided on opposite sides of'this'slot with exterior projections, 15, as by itting the sheet metal transversely and forcing outwardly a portion of the metal shell on the inner side of the slit, the projection thus formed terminating abwardly therefrom toward the inner'end of the sleeve. The cap" is. providedwith recessed portions or apertures, 17, arranged to with the position'of the projections, 15, on the shell and adapted to re,- ceive said projections respectively when the parts are telescopically applied toeach other with the projections in line with the correapplication sponding recesses.

clined from 'the inner end of the sleeve toward their outer ends Whereatthey terminate abruptly, the parts will interlock with a snap-action when telescopically applied to each other. To insure the alinement of said projections cap, the edge of the cap is provided with a receive ,a projection, 20, sleeve and guide the parts in their telescopic application to each To facilitate asse1nbling,,inent of the and is provided the difference indiameter is so outer end and lnclinlng 1n-' The sleeve being com pressible and said projections beveled orin- 55 i that said displaced and recesses during telescopic to each other of the sleeve and diameter thus transverse slit, said sht being other with the interlockable projections and recesses of the shell and cap respectively in alinement. The projection, 20, is preferably formed by displacing outwardly a portion of the sleeve wall between two longitudinal slits whereby when said. projection enters the slot in the end of the cap rotative movecap relatively to the shell is effectively prevented by engagementof the out edges of the displaced portion of the shell with the cut edges of the slot-walls. Theprojection, 20, may be formed in any known manner. The cap and shell or sleeve havetheir edges opposite their interlocking pprtions continuous or unbroken, the projection, 20, and slot, 19, forming the sole guiding means for telescopically applying the parts one to another. The cap, which is provided with a central-aperture for the passage of the circuit wires, has an insulating washer, 21, secured therewithin by inward projections formed on the cap, the capwall being provided with transverse slits andportions, 5, of its wall on the outer side of said slits being introverted, the insulating washer which has a continuous circular periphery being secured'between the end-wall of the cap and the cut-edges of said introverted portions. This construction permits the washer to be easily snapped into place and serves as an elfective accidental removal.

The sleeve, 12, has opposite ends of different diameters connected by a tapered intermediate portion, 22, in the usual manner, with an insulating lining. comprising insulating tube sections .of different diameters adapted to fit within the respective ends of the shell. It is desirable to have the lining for the shell of tubular form, but it is difiicult-to make a tubular lining of different diameters at its opposite ends, as great that the tubing is weakened or broken either by expanding to the larger diameter a portion of the tube of'the smaller diameter, or by compressing to the smaller diameter a portion of the tube of the larger diameter. In providing such lining for the shell we employ two sections of tubing, one 'ofthe smaller diameter and the other of the larger diameterand. displace the neighboring ends of said tube sections, thatof the larger tube by contraction and that of the sion to approximately the same diameter so ends abut one upon the other. The displacement thus necessitated is inconsiderable and is effected at the ends of the tube sections which yield readily tov manipulation. The, tube section, 25, of larger abuts upon and prevents the escape of the section of smaller diameters, 26. The shell is provided in its inner end with a,

introverted at, 23, and.:-the.-

smaller tube by expan the Wall'on the inner side of sec ed within the shell larger section of insulating tubing is pr0- vided with a notch, 24, in its inner end ada ted to receive said introverted portion pf t 1e shell. The larger tube section is thus between'the portion thereof of smaller diameter and the cut'edge of the introverted portion 23. The tube sections of difiering diameters may be secured within the opposite ends of the sleeve in any known manner.-

This invention permits the use of ordinary insulating tubing which can be cut up into sections of desired length.

By insulating tubing we mean insulating material in unbroken, substantially cylindrical form, as distinguished from sheet material'bent up to slitted or split tubular form.

If desired, the clamping-plate may be -d.i-

vided into two members, and 27, as shown in Fig. 16, each of said members being pro vided with a screw-aperture, 28, and an indentation, 29, adapted to enter a correspond- 1.
