An electric .lamp unit, generally indicated at I1,.comprises a main body casing or shell which is made up of an upper section I8 _and a lower section I9, each section being substantially semi-circular in shape in transverse section and being joined> along‘their horizontally disposed edges so that transverse sections of the assembled sections forming the 2,106,231 main body portion or shell are substantially cir cular in form. The sections' are extremely long and are curved longitudinally gradually tapering toward the rear to give a streamèlined effect and to close the rear end, the casing terminating in an opening in the front end. The lower section has an outwardly and horizontally formed iiange 20 extendingtherearound and the upper section has an outwardly extending ñange 2l of greater 10 length than the flange 20, the flange 2I being rolled over and clamped to the flange 20, as best shown in Fig. 4, to form a horizontal ñn or bead around the head portion of the lamp unit and rigidly securing the two sections together. The 15 front edge portion of the sections I8 and I9 are oifset inwardly around the periphery thereof at 25-.to provide a seat for the front or retaining ring portion 28 when the sections are assembled. As disclosed in the copending application re 20 ferred to, when dry cells become exhausted they very'often expand, and if they initially ñt their holder with any degree of tightness, upon ex pansion they will become more tightly held with in the holder often freezing therein and making 25 it exceptionally difficult to remove them when it is desired to insert new batteries. Since it is desirable that the dry cells be securely held in position at all times, a resilient holder which will securely hold the cells when initially placed 30 therein but' which will permitl their expansion upon exhaustion and yet permit ready removal of the exhausted dry cells is provided. . - It is evident that as the present 4invention is directed to a lamp unit which is relatively small 85 in size that assembly of the elements making up the unit is a diñicult problem, as relatively small spaces are available for the reception and manipulation of tools for securing the parts rela tive to each other. The-present invention pro ~40 vides a structure by which the construction and assembly of the elements to provide the unitary lamp structure are relatively simple. According to the present invention a. unitary mounting or supporting member generally lindi 45 cated at 3D is provided for mounting a lamp re flector 32, dry cells 34, and an~ electric switch element 36. The holder or mounting member 30 comprises an elongated substantially cylindrical resilient sheet metal member 38 having a longi 50 tudinally extending slot 40 throughout its length. Dry cells 34 are resiliently and removably held in the cylindrical portion 38; 'and in the illustra tion shown two dry cells in series are mounted within the holder, but it is to ,be understood that 55 the holder may be of such a size and length that any desired number of dry cells may b-e mounted therein. By constructing the holder of resilient or readily yieldable material and providing the slot 40 it can be seen that upon expansion of the 60 exhausted dry cells that they may be removed ‘l Without undue binding Within the holder. A longitudinal extension 42 is formed integral with the cylindrical member 3B adjacent the rear and lower end thereof, _the extension 42 being 65 formed to conform to the shape of the shell con tacted by the extension when the parts-are as sembled. The extension member 42 is provided shoulder of the rivet thus engages the upper surface of the extension 42 within the'slot 44. The electric switch element 36. is mounted to the extension 42 by means of rivets 48, or the like, which extend through openings 58 provided in the extension. Another opening 52 is provided through the extension 42 to receive therethrough the shiftable button 54 of the switch 36. The opening 52 is of course of such a length as to permit shifting- of the button 54 within the open 10 ing. The- switch 36 is thus secured to the exten sion membertâZ before mounting the holder 30 within the casing which is a relatively simple operation. When mounted within the casing the button extends through an opening in the casing 15 corresponding to the opening 52. In order to removably mount the reflector 32 to the mounting member 30, a J-shaped slot 56 is provided in the front edge of the holder 3U with the edge opening of the slot substantially dia 20 metrically opposed to the front edge opening of the elongated slot 40. Another slot 51 is provided in the holder 30adjacent the front edge thereof, ` the slot 51 opening into the elongated slot 40 at substantially right angles thereto. These slots 25 thus provide for removably mounting the re ñector 32 to the holder in a manner to be de scribed. _ The reflector 32 is preferably. so constructed that it may be mounted in an oii’set relationship to the horizontal center line of the casing unit, so that the light beams reflected therefrom will be directed downwardly to form a bright spot in front of the bicycle close to the lamp when the lamp is mounted on the bicycle. with'its center line in a substantially horizontal plane. 'I‘his is accomplished preferably by constructing an extension 58 on the front of the main parabolic section BIJ of the reflector, the extension extend ing around the front periphery of the parabolic 40 section, having its greatest width at the bottom and gradually diminishing in width to a point at the top. The reflector 32 is‘ provided with rearwardly and radially inwardly extending lugs 62 and 64 Which are formed on the reflector 32 45 ’in diametrically opposed relation. The lugs 62 and 64 are of such a- width that they may be re ceived Within the front edge opening of the slots 56 and 40 respectively, and upon a slight turning ' movement the lugs are held within that portion of the slot 56 parallel with the front edge of the member 38 and the slot 51 respectively. The openings through the front edge formed by the slots 40 and 56 respectively are preferably of _different widths, with the lugs 64 and 62 having 55 correspondingly different widths so as to prevent the userL-or one assemblying the lamp unit, from getting the offset reflector assembled in place upside down. ‘ . In order to support the holder 30 within the 60 ycasing adjacent the front thereof and to support the holder in spaced relation to the walls of the casing, a bracket portion 66 is formed integral with the holder 30 and downwardly offset there from. The bracket member- 66 may then bé se 65 cured to the casing by means of the rivet 68 or the like. , with an open or U-shaped slot 44 in its rear edge 'I‘he details of the switch 3B per se are disclosed 70 for securing the holder 30 to the casing at the wardly spaced from the inner wall of the casing in the copending application referred to above, and the switch is preferably located between, the batteries and the shell in the ground circuit. The switch comprises a U-shaped Contact spring ele member for reception within the open slot 44 ment 'I0 which is rigidly secured at one end to rear edge.
