The aperturings 31, 98, in 'a man- ' respectively, the trailing edges of the detents 36, ‘also form radially extending portions I33, then being opposed to the’ radial‘edges 34 of the , I31 adapted to cooperate. with the hooks of the detent-receiving ‘aperture portions 33.

The parts are then in the position'shown ner. described in‘ connection with the aperturing 'nector portion36. > » I, 1 I In the event that it is desired to manufacture '10 the socket unit out of sheet material, a blank, /such as illustrated in ‘Figure 4, is ?rst stamped out and shaped to the form shown in Figures 2 and 3, where the portion 35 forms a cylindrical ‘shell and the integral connector portions 36, 31, 15 38 are shaped so that the axially extending por tions .33 along with the hook-shaped endsthereé of'are of arcuate cross-section, the arcs being‘ of vthe same radius, and concentric with the axis’ of the shell 35. 20 ,- - / . The contact carrier is then inserted into the shell 35, with the projections 52, 53 in the recess 54, 55 in the end of the shell, the projection, cor responding to the projections 52, 53, not visible inFigure 3, being received in the‘recess 53in the end of the shell. The ?ngers 51 are then clinched ‘ over the rear end of the. contact carrier 5|. in Figure 9 in which the re?ector, with the socket unit . assembled therewith,‘ is viewed from. the front. The fit of the arcuate connector portions 10 ' 36, 31, 38 in the arcuate apertures 83, 33, ‘3| may be snug enough to gaugeor locate the connector portions ‘with respect to the re?ector.v ' I a If it is now desired to mount with the re?ector‘ a lamp, such as thelamp 23 of Figure 1, the 15 largerportions 33 of the aperturings 96, 31, 33 are brought into registry‘with‘ theendsof the books of theconnector portions 33, 31, 33. .lamp is moved } toward the re?ector against the 'bias of thespring-pressed contacts 53, 63, until 20 the projections, such as 33, corresponding to the indentations 33, 3|, 32 abut‘ the front surface of the ?ange 28. If'the lamp'is then turned in a clockwise direction, as viewed from the front of the re?ector, the edges |3| of the aperture por- 25 tions 33 of the aperturings 36,‘ 91, 98 will engage respectively the beveled portions 43 of the hook The ring 13"of the biasing means may he slipped, from the rear, over the connector portions 36, 31, 38, the narrow portion 84 of the apertures 8|, 82, lips and *by cam action will pull the connector 30 83 passing freely past‘the reduced portions 43 of portions 38, 31, 38 further through the re?ector the connector portions 36, 31, 38, and the undercut against the bias ‘ of the‘biasing means 12.‘ Con- 30 portions 85 of the apertures 8|, 82, tinuance of the clockwise rotation of the lamp will cause the apexes I33 of the lips of the hooks to ride over the front face of the radially extend freely along and receiving within themthe ‘neck portions 33 of the connector portions 36,- 31, 38. 35 The ring 13 is moved towards the ends of the. ing portions I35, I38, I31 and then the apexes I38 of the hook lips will snap. respectively, into 35 the smaller aperture portions I33 of the apertur connector portions until the front face of the . ring '13 abuts the apexes I38 of the lips of the The spring loops 14, 15, 16 are then ?exed ' lugs 36, 31, 38._ The hooks now have the‘ position hooks. , so that the respective free ends 11 thereof are ' illustrated in Figure 12.“ Here only the connector" ‘ 40 portion 36 is shown, but all of the connector por tions assume a similar position- In that posi-‘40‘ radially inwardly into the openings 18, tion the sides 45, 46 ‘of the hook mouth straddle the shell 35, taking the position illus trated in Figures, 1 and 6, in which the ends 11 45 underlie the inner periphery of the .shell. The, assembled socket unit then has the appearance, I in side elevation, asillustrated in~Figure 6, and inc-front elevation as illustrated in Figure 7. 50 The socket unit may now be connected to a and I 33 respectively of the radial .portion I35. .5 The biasing means 12 of course presses the ?ange 45 25 toward the front face of the re?ector, and hence presses the projections 33, corresponding to the indentations 33, 3|, 32 into abutment with the front of the re?ector ?ange 28. Since these projections are in radial alinement with the 50 radialportions I35, I36, I31 against which pres sure is applied to bring the ?ange 25 into regis try with the re?ector, distortion of the ?ange re?ector by inserting the endsof the hooks of the connector portions 36, 31, 38'into the aper-‘ tures 89, 33, 3| in the re?ector. The ring 13 then abuts, and more particularly the frontwardly ex tending detents 86, 81, 88 abut the rear of the ‘ ?ange 28 of the re?ector. The circumferential 25 by that pressure is avoided; The lamp may be assembled with the position- 5;, width of the hooks between the outer axial edges 42, 48 thereof, is greater than-the circumferential ing means 23 by placing the'positioningmeans width of the respective apertures 83, 33, 3|. on a standard with the lamp base within the Hence as the .hooks'are inserted in those aper 60 the radial portion I35, of the lamp base ?ange 25, those sides‘ being in‘ contact with the edges IN tures the beveled edges 41‘ of the ends of the throats of the hooks will engage the respective radial edges 34 of those apertures. By.turning the socket'unit 34 bodily in a direction such that the beveled portions 49 of the hook lips engage the radial edges 35 of the apertures,,83,‘f33,-;9| respectively, the resulting cam actionbetween those beveled edges ‘and the radial edges 95 pulls collar 24 and then adjusting the lamp until the lighting center of the desired ?lament thereof is in a predetermined position, whereupon the col lar 24 is soldered to the lamp-base. The posi tion of other ?laments of the lamp may be like wise predetermined. It will be evident from the foregoing that my invention provides a means w ,ereby a lamp may 65 be connected to a re?ector with the lighting cen the connector portions 36, 31,38 further through ter of a ?lament thereof at a predetermined , the re?ector‘ apertures, against the increased point with respect to the re?ector, and also that 70 bias of the biasing means 12, until the ‘apexes the position of the lamp about its axis will be pre I38 of the lip portions of the hooks ride onto the front surface of the ?ange 28. ‘Su?lcient ro tative movement of the socket unit in ‘the same direction causes the detents 86, 81, 88 to snap into the portions 33‘ of the apertures 83, 33, 9| determined so that the proper contacts thereon 70 will be brought into engagement with contacts on a socket unit which in turn has the position of its contacts about the axis of the socket pre determined with respect to the re?ector.
