4 Claims. (01. 173-s5s) The present invention is for an improvement interior thereof and near their lower edges, Fig. in electric lamp sockets or husks, and while not 5, are provided with blind ended grooves l3l3, limited thereto, is more especially related to miniwhich are diametrically opposed to one another, ature electric lights or lamps such as are used in these being also arranged so as to be symmetri- 5. the decorative lighting of Christmas trees and cally located midway between the wire entrance other similar ornamental use. slots Il-| 1, best indicated in Fig. 5.

lhe important feature of the present struo- In the interior of the husk body I, Fig. l, is ture is in the provision, in a husk of this type, of fixedly mounted a metallic, conductive, threaded a minimum number of parts, to obtain a finished. lamp socket receiving ferrule 3, having an insafe and practical structure, and wherein said tegral bottom 9, the bottom being provided with 10 parts are simple, easily and rapidly assembled 'an. enlarged aperture 8, out of which is blanked into a unit structure and are extremely neat in an outstanding contact lug 1, Figs. 1, 4 and 8, appearance. which stands at right angles to the bottom 9 The foregoing, and other features of advantage The web 6 .of the husk body I is provided with a 5 will be noted as the herein description proceeds, ferrule lug receiving ape tu whereby,

and it will be obvious that modifications may be when the ferrule 3 is mounted in operative posimade in the structure herein, without departing tion i the y the ferrule contact lu 1 profrom the spirit hereof or the scope of the apjects through said aperture 3' to below the botpended 1 im tom of web 6, Fig. l, to permit the afiixing there- In the drawing, to of a conductor wire W, preferably by soldering, 20

Fig. 3 is a side elevation of the husk, enlarged, The socket ferrule 3 is held fi ed y in awith portions broken away, to better show ceriv p i n in t h y m n f a pier e 25 tain parts; dielectric disk 4, which acts as a clamp to hold Fig, 4 i a, bottom i w of Fig, 1; the bottom 9 to the web 6 by means of a single Fig. 5 shows a fragmentary portion of the husk v t w c y reason Of ts exposed ends enlarged with portions broken away to better on pp e Sides of the d 4 and Web acts h w th i t i d t il also as a conductor for the central terminal con- 30 Fig. 6 is a side elevation enlarged, of the husk tact Of a light b he ower exposed end. of closure cap; the rivet 5 also acts as a point of attachment to Fig, 7 is a, plan view thereof; and the other conductor wire W, as in Fig. 4. Fig. 8 is a bottom View of the threaded socket After assembly to he p in above d s ferrule, enlarged. the open lower end is closed by a snap closure,

As in Figs. 1, 2, 3 and 5, the husk body portion which is moulded of a compound similar to that l, i m uld d from itame m ti having didescribed for the body I and which is disclosed electric properties, such as a phenolic condensain detail in Figs. 6 nd This closure comtion compound and is made in the form ofan prises a head portion 43 having an interrupted 116 approximate cylinder, as to its interior, has an Outstanding flange, generally de ote by Sa d open, flaring lamp socket directing end 2 which flange being pr vi wi h pp openings m r int th body portign I4l4 ending at the stepped sections l8l8 of The opposite and relatively lower end of porthe flange, Said Openings, W the closure is tion I is also open and near the open lower end fitted t0 the husk body, ste ng With the 45 the body is traversed by a web 5, which has an Openings of said u h tly, to jointly 4.5 axial perforation 5' therein Fig. 5, to receive a form Complete 001111116501 Wire p s for the rivet 5, Figs. 1 and 3. wires W, W, as in Figs. 1 and 4.

The lower open end of the body I is provided The Opposed, uninterrupted po tions of the with two opposed openings ll-Il, Figs. 3 and 5, flange F, between Openings l4 on their which, in the present instance end at the outer outer perimeters are provided With raised beads 50 face of web 6, Fig. 5, thus to form, in part, openl6l6, Figs. 6 and '7, the circumferential length of ings to receive conductor wires W-W, Figs. 3 and i h corresponds to the length of t grooves 4, and dividing the lower end into two portions I 3-| 3 in portions |2l2 of the body I, and when i2l2. the closure is in position, as a bottom cover, as in The lower ends l2l2 of the body I, and in the Fig. 1, it is locked in position by said bead and 55 groove structure to register the Wire openings i4l4 and H-H in cooperative registered positions, as in Figs. 1, 3 and 4. In closing the bottom of the husk with the closure the interrupted beaded flange thereof, as indicated: in Fig. '7, being relatively thin, is flexible enough to snap into and out of groove engagement with the husk, but when engaged, is held firmly against accidental displacement.

The head iii of the closure, Figs. 6 and 7, extends beyond the beaded flange i6, as at H, to provide a stop seat to engage with the lower end of the husk, as viewed in Fig. 1, and is preferably of the same exterior dimension of the husk at the point of engagement.

The flanged portions |6-H3 of the closure are provided at their interrupted ends, adjacent the openings l Z-I i, with thin upstanding lugs 15-55 and ii5, these being so contoured ,as to act.

as entering guides when placing the closure on the'body i, and also to act as means to prevent the wires W, W from getting out of operative positions when initiating the closure of the husk body i.

From the foregoing description, it will be noted that aside from the rivet 5 and wires W, W, there are only four parts to the present construction, and owing to the simplicity of construction and the few parts involved, the operation of assembly of the completed article is simple, and extremely rapid, and thus is conducive to low manufacturing costs with a consequent saving of labor and outlay.
