My invention relates to new and" useful in"- provements in lamps for automotive vehicles.

An important object of my invention is the provision of a lamp construction that is particularly and uniquely adapted to accommodate the relatively new sealed beam type of lamp to the older types of lamp bodies.

Another object of my invention is the provision of an adaptor construction of the abovementioned character wherein the constituentparts comprising the same are uniquely asso ciated in a manner whereby they may be easily and expeditiously fitted to varying sizes of lamp bodies with a minimum of expense and labor.

Still another object of my invention is the provision of a lamp construction of the abovementioned character that is capable of being easily and quickly assembled so that when the several parts are positioned to hold the sealed beam unit within the lamp body, the said'unit will. be securely but resiliently maintained cation, and wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective view of an automotive head lamp body and rim, and showing a sealed beam typeof lamp secured thereto. by means of the adaptor construction embodying the present invention,

Figure 6 is a perspective view of a spring clip embodying apart of my invention.

In the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral Ill designates a lamp body of conventional shape and constructionhavin an attachingstud H- extendin-g'therefrom: to provide, means for securv ing the head lamp to: an automotiveyvehicle; Theconductors I 2 are received; W-ithinethe body,

The sealed beam lamp; constitutes a rev flector l 6 'hermetieallysealed by the lens 5-l l l which 5: is fitted into the open; side IBthereof; and-the bulb l -is'disposed withinthereflector. at; substantially the; crownthereof. The-.sealedbeam typeof; lamp is; manufactured as a.. unitand possesses decided advantages over the older-types- :10'f' headlights; Thehermetically sealed con-..--

struction prevents;moisture-from gaining; access to the interior-of the'reflector and: rusting; cor rodingortarnishingthe-same. This lamp-there-- fore, offers a more brilliant light and; because of its unique,- construction, it will retain'its brilliancy and efficacy 'for its; entire life. These lamps are smaller and/more compactrthanthe. older type of head= lamp and, therefore, cannot be" appliedthereto; without an adaptorconstrue.

-. tion-suitedtofit.both the'older' type of-lampbody andthe sealed beam unit;' Thepresentinvention is directed to an. arrangement that-is; uniquelyadaptedtohold the sealed beam unit: within an older and larger body.

It is" to be understoodthatwhile I have-here, shown anadaptor construction. which is. par---- ticularlysuited to accommodate; the sealed. beam unit to: another and larger head lamp, body, I do not wishto restrict-the scope of the invention to this construction. The "sealed;

beam unit may be applied to. any larger casing,

of widely varyingshape and-sizeby means of the. adaptor unitcomprising the presentinvention.

The open end of the body H1,- islformedr with;

an inwardly offset annular flange-20, the edge: of.

which curves inwardly. asat 2-1; The-rimll has the opposite edges, thereof rolled. radially and.

inwardly and the. rearwardedge 32 thereof. is.

fitted within the 1 recessdefined-- by the inwardly offset flange 20-.

The reflector IB-ofthe lampunit l5 isformed. atits open side withan annular bead. 23;, andv the annulus 242 receives the lens H: and. is seated. againstv theouter face of thebead. The lamp unitsv l-5- are of a standard; size and the: inner.

periphery of the annulus may, therefore, be easily fitted thereto. The head lamp bodies It], however, vary slightly in size and I have, therefore, found it is advisable to make the outer periphery of the annulus 24 of a fairly large diameter and to thereafter cut the same to the desired size. Of course, if a great many of the lamp units l5 are to be applied to similar housings H], the annulus could be made with both the inner and outer peripheries of the requisite size. The outer peripheral edge of the annulus is received between the inwardly turned edges of the rim and with the outer face thereof seated against the inwardly turned forward edge 25 of the rim.-

Lugs 26' are fixedly secured to the rearward face of the bead 23 at spaced intervals therearound and screw-threaded bolts 26 extend inwardly through the annulus 24 in slight spaced relation thereabove. Nuts 21, carried by the bolts 26, have the edge 28 thereof bent at right angles thereto in a manner to engage below the extending lugs 26', whereby rotation of the bolts 26 will move the nuts into interlocking engagement with the lugs to hold the annulus 24 in tight pressed relation with the forward face of the bead.

As illustrated in Figure 2, the outer peripheral edge of the annulus extends slightly beyond the outer edge 25 of the rim and the spring clips 29 are associated therewith at spaced intervals therearound to hold the same in pressed rela tion with the rim. The spring clips are formed with a depending Ushaped middle portion 30 adapted to engage the rearward face of the annulus, and rearwardly extending resilient arm portions 3| adapted to have the free ends thereof seated above and retained by the inturned rearward edge 32 of the rim, as illustrated in Figures 5 and 6. The spring clips 29 are disposed at spaced intervals around the annulus and the arms 3| thereof should be sufficiently rigid to hold the outer periphery of the annulus in appressed relation with the forwardinturned edge 25 of the rim.

The edge of the flange 20 is formed adjacent the top of the body I with an inwardly and upwardly bent ear 33 which receives and supports the end 34 of the substantially U-shaped spring clip 35. The opposite end 36 of the spring clip extends through an opening 31 in the flange and engages the rearward edge 32 of the rim to hold the rim securely seated upon the flange. The body II] has the keeper 38 welded, or otherwise secured, thereto adjacent the bottom thereof which keeper includes a pair of spaced fingers 39 extending outwardly of the body through the opening 40. The catch element 4| comprises a shank 42 pivotally secured to the rim. The sliding block 43 is carried by the shank and'the free end of the shank is enlarged whereby the coil spring 44 interposed between the enlarged end of the shank and the block 43 will hold the said block in pressed engagement with the keeper 38 and the shank 42 detachably disposed between the fingers 39.

In assembling the adaptor construction the annulus is first applied to the sealed beam unit I by means of the bolts 26 and nuts 21. The annulus may then be inserted within the rim 22 and detachably secured thereto by means of the spring clips 29. The spring clip 35 may then be applied in the manner hereinabove described, to hold the top portion of the rim in locked engagement with the body, and the lower portion of the rim is then swung inwardly,

seated against the outer face of the flange 20, and the shank 42 pivoted into latched engagement with the keeper 38.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention, or scope of the appended claims.

Having thus described my invention, I claim:

1. The combination of a lamp body having an opening and a radially and inwardly extending flange surrounding the opening, the said flange being formed with an inwardly offset portion at the juncture thereof with the body, a lamp having an external annular flange located within and spaced circumferentially inwardly from the flange of the body, an annulus extending radially outwardly from the lamp to the lamp body, the inner marginal edge of the annulus seating against the outer face of the external flange of the lamp, a band having the opposite marginal edge thereof rolled radially and inwardly, the outer marginal edge of the band being arranged to abut against the outer surface of the annulus and the inner rolled edge thereof seating snugly in the inwardly offset portion of the body flange, means detachably connecting the annulus with the lamp, said means comprising lugs on the flange of the lamp, bolts extending through the annulus and positioned outwardly of the lugs, and nuts threaded on the bolts and provided with portions for interlocking engagement with said lugs, means detachably and yieldably holding the annulus in pressed engagement with the front marginal edge of the band, and means detachably connecting the band with the said lamp body.

2. The combination of a lamp body having an opening and a radially and inwardly extending flange surrounding the opening, the said flange being formed with an inwardly offset portion at the juncture thereof with the body, a lamp having an external annular flange located within and spaced circumferentially inwardly from the flange of the body, an annulus extending radial- 1y outwardly from the lamp to the lamp body, the inner marginal edge of the annulus seating against the outer face of the external flange of the lamp, a band having the opposite marginal edges thereof rolled radially and inwardly, the outer marginal edge of the band being arranged to abut against the outer face of the annulus and the inner rolled edge thereof seating snugly in the inwardly offset portion of the body flange, lugs extending from the rear face of the external flange of the lamp, bolts extending through the annulus and laterally of the lugs, nuts carried by the bolts and adapted to interlockingly engage with the lugs upon turning of the bolts, spring clips having parts contacting the rear face of the annulus and parts seating within.

the rolled inner edge of the band, said clips being normally tensioned to hold the annulus in tight pressed engagement with the inturned outer edge of the band, and means detachably connecting the band to the body.
