AssIeNo a PANY, or conuivrnusoiama conronarron or 01110 LAMP 'coiisraucirion Application filed September 14, 1931;

This invention relates to lamp construc tions more particularly d rected to that type of lamp used for ornamental purposes, pm-

as ambulances, hearses, delivery trucks, or

and which, when in use or iighted, will give I is other vehicles of like nature.

- -An object'of the present invention is to provlde a lamp of this character which will have an ornamental and pleasmg appearance a crystal or star-like effect and add to the dignity and character of the vehicle upon which it is carried.

Another object of the invention lies in the provision of a lamp of this character in an extremely simple construction is pres ent, rendering the same particularly desirable from a manufacturing and assembly standpoint, and which when in use maybe readily serviced.

With these and other objects in view, wh ch will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts hereinafter to be more fully described and pointed out in the appended claim.

In the accompanying drawing: 7 Figure 1 is a front elevation of comprising the present invention,

Figure 2 is a side elevation thereof,

Figure 3 is an enlarged vertical sectional view taken through the lamp as indicated oy the line 33 of Figure 1, and

Figure i is a horizontal sectional view taken on the line k4: of Figure 2. V

Referring more particularly to the drawing, the numeral 1 designates the lamp in its entirety which is formed to comprise a vertically arranged substantially cylindrical housing 2 which has its upper and lower ends closed by means of end membersB ands formed and shaped to give an ornamental appearance to the lamp. To further ornament the lamp the cylindrical side wall of the lamp the housing 2 at the front and sides thereof is provided with a plurality of light openings in the form of cut-outs or slots 5 which extend substantially the full height of the housing and are separated by webs 6. These webs bracket 9 attached wherei upon a conically ILeading to the lam'pis ductors 22 which enter Serial No. 562,758. have their outer faces ornamented, byforming therein longitudinal corrugations which enhance the beauty strengthen the webs. of the housing such as by rivets or thellike 7 is an anchoring'casting 8 which is adapted to'be received within a substantially U-shaped The casting is held in" place within bodyj 'the bracket 9 bya'boltmember 11-"pass'ing vertically through aligned openings formed insaidbracket and casting andfwhich *bolt.

the threaded lock' nut is reta ned in place by is positioned snugly 12. ,As the casting 8 within the brackett), the'lamp will bese'cured in place therein in a rigid manner relative to its supporting structure;

I Arranged within the .drical lens or transparent member 13 which is of such cross-sectional area as to snugly r0 COLUMBUS AUTO BRAsscori- .to a supporting member 10'which may bethe roof pillar of a; vehicle housing 2 is a cylinof the .lamp as well Yes .Attached to the back engage with the inner wall surface of the housing, and which is of such length as to com pletely cover the elongated Islots or openings 5; The lens member 13, which is in the'shape of a glass tube having open ends, isheld in place within the housing between the lateral shoulders 14 formed upon upper and lower concaved reflecting members 15 and 16 respectively. The lower reflector member 16 rests has its lower end engaging the restricted lower tapered end of the end member-4 and its upper end engaging a shoulder 18 formed upon the reflector member 16. the probayonet slot connectionQOby which the indetachably connected.

candescentlamp 21is e,

a pair of electric-conthe housingth'rough a sleeve 23 formed in the upper end member 3 of the lamp. Theconductors22 may pass toany'convenient-point on theligh'ting circuit of the vehicle and the incandescent bulb shaped coil spring 17 which looseness of the parts.

21 may be supplied with current from the usual battery of the vehicle. Arranged immediately to the rear of the lens and positioned between the lateral and the rear portion of the housing is a convexly shaped refiecting member 24 which extends the full height of the housing 2 and which may be attached thereto bysolde'ring the same in place or in any other manner'well known "in the art. This reflecting member,"which=is provided with alhighly polished inner surface built together with'the polished-inner surfaces of the members 15 and 16, reflects light rays from the lamp bulb 21 outwardly and forwardly through the lens covering slots or cut-outs 5. This reflected light may be divided into separate beams by the webs 6 therebypr'oducing a multiplicity of lightrays which together with a multiplicity of reflecting surfaces will give what may be called a crystal like effect which lends a distinctive appearance'tothe vehicle.

- {To hold the lens member 13 and other various parts in their assembled relationship,

the upper edge of the housing 2 is provided with bayonet slots 25 for cooperation with .pins 26 carried by the lower cylindrical edge :27 of the upper end member 3. By means of this pin and bayonet slot connection the end member}, willf be held in a locked position upon the upper end of the lamp housing and will also serve to exert a downward pressure upon the lens 13 against the action of the spring 17, which spring pressurewill prevent jaccidental displacement of the member 3 relative to: the lamp housing. A gasket 28 may be positioned between the upper of the ifianges 14 and the end member 8, which serves asadditional cushioning means for the sup- ,port of the lens and prevents rattle and From the foregoing it will be seen that a construction has been provided which is extremely novel and wherein the parts are so arranged as to be readily assembledffor service;- The lamp when in use will give an junusuallighting efi'ect due to the formation ofthe lamp housing and the provision of the vertically arranged, separated slots of light wmdows therein. By the arrangement of these light openings together with the concave ,upper and lower reflecting members, which -are visible through said windows,'the light from the lamp will be reflected and split up intolamultiplicityof rays producing a light of h ghly unusual character. The lamp may bereadily serviced, for the replacement of a bulb therein or for the "cleaning of the lens,

by the detachment of the upper end member The. conical'or'nam'ental end members to- I gether with'the longitudinalribs or corrugationsjgive the lamp a design which has a pleasing appearance.

. what is claimed is:

,Iii-alamp or the; character described, a ver- 7 tically arranged cylindrical housing having spaced longitudinally extending slots formed therein which extend over the forward and side portions of said housing, the unslotted portion of said housing carrying a reflecting surface, upper and lower end members of ornamental form closing the ends of said housing, a cylindrical lens within said housing and a bayonet slot-connectionbetweenthe upper end ofthe housing and thecupper of said end members. v V V In testimony'whereof I afiix my signature.
