The lamp i-iiay be stipported iii aiiy desii.ecl 10 manner as by the usual flexible coiicluctor 17 cr by,iiieaias of any suitable frame or bracli:et, Ail-iereby lio,ht fi-om the lamp iiiay be projectecl upoii the desired object. Wliiie iii Figs. i and 4 1 have ilIListrated ]@5 suppoi-ting arms 5 for the i-eflectors 2 ,is adapte6t to be bent as desired to cause the i-ays of light from said reflectors to be project,.,d at the desired angle for concentr,t,iin- rays from all of the.- reflectors upon 20 aii object, said reflectors m,,ty be supported for adjustinent at will for castino, rays therefroin as desired, ine,,ins for whi@h purpose are sho%vn iii Figs. 7 and 8@ Each of th(- refloctors has a frame or backiii-, 18 se215 OUred to pi-ojection or al-i'll 19 pivot@l'ly supported upon f'rame 1, whiel-i fi-ame in Fi-,s. 7 and 8 is shoivn in the foriii 6f a ri,n@@-li@e i'Vir-,. The arms 12 from said ring are ro@ p vided with meaiis to support socket 3, shown in the form of spring-fingers 10 secured to arms 12, ivhereby the socket foi- lamp 4 may @be retained cel'itrally disposed within the circle of reflectors 2. The ' arms 19 are shown.pii,otally conneetcd by links 20 -with a lamp iiaeinber 21 that is acljustably supported. I have shown member 21 connected Avith threaded member 22 by universal joint. I 23@ which threaded n-ieinber operates in correspondiii(Yly threacled membe@ 24 suitably supported, whe,,reby wlien inember 22 is rotate-,I the member 21,will be moved in one or aliother dir.ection and the arms 19 will be tilted, and retained in said position for varye in,g the position of the reflectors @@ith r _ 45 spect to liaht source 4. I have shown the shield 6 stipported by arnis 7 and nuts 8 upon arms 12 in.manner before described for retainiiio- the s.hield in froiit of the lamp. The i)arts described -with res -ect to Figs. 7 p 50 and @ are also shown enel6sed within a casing 25 in the na:tLire of head lights for alitomobiles, the member 21 being supported in ,t bearilig at 26 in saicl casing, wl-lich c,.isin 9 i-iiay be supported iii any desired man,ner; but the rim portion x thereof surrouiids and @projects forwardly of the indi@idu,,il reflectors thereby acting as a side shield f6r @preve@iting lateral dispersion or zlare of the light. The glass or leiis 27 at the front of 60 the casipg 25. may be slipportecl there6n in any de,sireld or well ImoAvn maiiner such as by j@ing 28. With the arrangeinent described the aiigle of the reflectors 2 with respect to the electric li.ght 4 ma@ be varied as desired so a@ to clause light projected froin the lainp to be cast forwardly from the autoinobile at des red points towar or ul)oii the road. By means of my improvements t rays of light from the, light source 4 wi e pi-ojectecl directly upon the reflectors 2 as iicll as stich rays reflected on said reflectors fi-oiii the reflec-tor shield 6 -which rays will be 6oiisolid,,Lted and superimposed Lnd will I)e projected tb ,t desired position in accord- 7i aiiee Avith the distance from the lamp of the ok)ject to be illuminated and with respect to the aiinular relatioii of the reflee-tors 2 to @tlie light source 4. All 6f such rays conilei-o-e to a, focal point and by varyin the 80 t@ 9 aiigle of reftectors 2 with respect to the light SoLii-ce the aret of li(yht cast from said reflecfo@s upon an object a-t a given dist,,tnce iiia3, be increased or diminished as desirecl. The reflecting illirrors 2 may be of such 85 cl-iarl@leter as to cause light rtys fr6m the source of ll!-@lit to be magnified and to magthe Nvhiteness of tlle lioht from the filameiit or ai-c of the licrht s-ource whereby a brilliaiit light may be produced. By means UD of iiiy iiii,entioii the reflectors receive the light directly from the lamp filament in such a i-fianner as to reflect such light forii@ai-d tipon a given space to incre,@se the iiite-,isity of the lioht thereon. This result 03 is effeel-ed lb37 reds( n of the series of spaced concave reflectors located behind the light sotirce aiid, iii positi 11 to project the rays foi-",ard arolind tlie, light an,d its shield to a gli,ei-i positioi-i. The imaee of the lamp !LIO E-laiiient -with its ftill lizht intensity is receii,ed by the reflectors and is projected therefrom f orward to the focal point, a series 0-f briglit illiages of the intense light of the filaiiient being outlined aiid by using the 105 light on aii object tt a predetermined distance from the liaht source superimposecl r,,tys fi,oin the :teflectors give a brilliant and ii-itense wliite light on the object without the o-lare that -would be produced by the direct 110 rays from the lio,,ht source. By reason of fhe ann-Lilar -,trrangement of the reflectors the light is projected forwird upon an object to bo illuminated in a. manner to minimize shadows as for ilistance, if the hand 115 7 or fingers of . an operator be interposed in t. por@ion of the ligl-it cast Lipon 'an object the remainder of the light will be so stroiig as to in,,iintain a satisfactory illumination 120 of LI-ie object. i@ly projecting lanip is particularly useilil for projecting brilli,,tnt, strong light dii-ectly ul)on aii object, such as in the iiibuth or othe'r cavities of a I atient, or Lipon d-esired i),qrts of their bodies p for use of surge6ns for their operations on patients and for dentists. My improvemeiits, Llso may be used iii other relations, such as, for reading lamps, for head lights, etc. It-will be undei!stoocl th@t bv, me@ns of My 130
