drical extension for the elbow head to which the threaded lens ring N may be detachably con led.

he lens ring N has an annular' shoulder N that extends outwardly from the externally threaded part thereof to provide a shoulder `for supportng the lens G which may be a bulls-eyeas shown, a plain cover glass or of any other section. The lens Cf. 1s held against the shoulder N by an inwardly spun front edge i ot the ring N, thus providin'f a lens and lens ring attach-able and detac iable a unit.

A suitable metal rellector ll is mounted in the head E so that its axis is perpendicular to the axis of the main body or easing C and is centrally sleeved and threaded as at lt to receive the threaded base L of the usual from the edges of the registering'openings l5 and 15 in thewalls W" and l-l, and at its forward end has an outwardly extending flange R whereby it is supported in operative position. While the reflector' may be supported in position and insulated in any desirable way, as shown, it is desirably mounted coaxially within ann insulating ring I of rigid material such as liber or hard rubber, At its rear end "the ring .I abuts against the shoulderiformed by the walls lV vand H. At its iront end the ring l is provided with an inner shoulder l against which the rear side of the rel-lector llange R abuts, the thinner outer` part l of the ring l being spun inwardly over the outer edge and the front lace of the flange R to secure the flange and reflector together so that they andjtlie incandescent lamp li may be easily removed and inserted as a unit. This unitary lamp, reflector, and mounting ring assemblage is held in place in the head by the unitary lens and lens ring assemblage already `descrilired and by indenting the side Wall of the head, as shown, these assemblages may be positioned more closely to the axis of the tubular body C to provide a shorter right angle leg on the head and a flashlight that is more stable when standing upright on its bottoni end. l/Vhen the lens ring is coupled to the head, its threaded part screws into the shell H between the latter and the insulating ring l, and the inner of the lens G engages the inturned outer end l oi the insulating ring.,r .l and clamps the latter' against the shoulder or (partition wall 'formed by the llenges l-l an i Nn The reflector is thus completely insulated from Qall parts of the casing and rigidly mounted in place.

Various means may be used to electrically connect the lamp L in circuit with the battory l Since the lamp holder E is an integral part of the' nietal reflector lt, e suitable conductorl be connected to eith The rel Hector R projects through but is spaced- Lacasse of these parts to' provide a circuit connection leading to the base L of the lamp. As shown, a semicircular, conductor strip 2O has a radially inwardly extending resilient prong 2O4curved or notched at its free end Which may engage the outside 0l the reflector at a point behind the wall Vv, the latter cooperating with the head E to form a chamber for the contacting, elements and rear ends of the reflector and lamp. The fixed end of the conductor 2() is in the form of a right angle, one leg 23 of which is secured to but insulated from the partition W', -l'by a rivet 24 and insulating

washers

25, 25, 25, the holes through the leg- 23 'and said partition being spaced or otherwise insulated `from the rivet to avoid. AContact of metal .to Y'nietal atitlicse points; The other leg 26 ofthe conductor 2t) is secured' to one side of an insulating abutment and contact disk 27 by a metal rivet 2S. The insulating disk 27 is held in place against 'the lower side ot a bead 27" in the cylindrical part of the elbow itting by the legs 23, 2G and the securing rivets 2l, 28.

The center Contact L of the lamp is engaged by the tree end of a spring Contact 29 that is supported on and secured to the disk 27 by metal rivets 29 and 29, the lat- 'ter beinfcr longer than the rivets 28, 29' and' securing a washer 30 to the under side of the dishY 27 so .that the lower end of the rivet 29 will engage the center contact B of the battery B and hold the latter away from the other conducting parts on the disk. A contact plate 3l is secured to the under side of the disk 27 by the conducting rivet 28 and similar rivets 2,8', and has an opening 31' separati ng it from the conducting rivets 29', 29.. The plate 8l is engageable in any re1- ative position of the head E and body C' by the inturned end 32 of a yieldable strip conductor 32 lthat-is associated with the switch mechanism ttor controlling the lighting of the lamp.

y As shown in Fig. G, the conductor 32 is secured by

rivets

38 and 34 to the free end of a still' strip of insulation that is sccured near its 'other end by rivets 3G and 37 to the inside ot the case C. One end of a strip of yinsulation 38 is secured by the rivet 33 between the outer free end of the insulating strip 35 and the insulating ring that abuts against an interior shoulder in the front threaded part ol the casing,r C, and te other end ol the strip 38 passes around the lower edge ol the ring 39 and covers the outer end of the rivet 33 to insulate it from the metal casing, The rivet Sli: extendsoutwardly through an opening 42 in the casing C and is insulated from the latter by a Washer 34: secured by said rivet. ',lae rivet Se provides a contact tor a cireit closer orrspring switch member t3 that is 4secured to a reciprocal operating member and clamping the lens against said insuiating rine.
