To all whom il! may concern: e

Be it, known that I, FRANK P. BENNACK, a citizen of the United States, residing at San Antonio, in the com ty of Bexar and I State of Texas, have invented a new and useful Headlight, of which the following is a specification.

ltis the object of this invention to provide a structure adapted to serre as the front wall ot' a headlight, to house the lens portion of the headlight and to serve as a mounting for a curtain. adapted to be drawn downwardly in front of the lens portion of the' headlight.

Another object of the invention is to provide a novel means for nuumting and proteetinga curtain adapted to be drawn in front of a headlight.

Another object of the invention is to provide a novel means for retaining the lens portion of the headlight in place. I#

Another object of the invention is to provide a casing adapted to house the lens prtion of a headlightin such a wry that the lens may readily be removedl a dosare for the casing being adapted to serve as a means for retaining the lens portion oi the headlight invplaee, and as a means for shielding a curtain adapted to be drawn in i'ront of the lens, and for maintaining the mounting of the curtain in place.

:Another object of the invention is to improve generally and to increase the elliciency of devices of the class hereinafter described.

The drawings delineate preferred embodiments merely, and it is to be understood that changes,. properly falling within the scope of what is claimed, may be lnade, without departing from the spirit of the invention.

the drawings, rigure l is a frontJ elevation, parts heilig broken away in order better to reveal the internal construction of the device; Fig. 2 is a transverse section; Fig. il is a fraglnental end elevation; Fig. 4 is adetail perspective of a spring which is employed for holding the lens portion of the structure in place; and Fig. 5 is a side elevation of a bracket which enters into the construction, the ligure being designed to show a modified means for mounting the curtain.

.The invention includes, as a primary and fundamental element, a easing. This casiug is shown iii the drawings detached from the headlight of which it is designed to be-- 'depeuds between the walls l and 2 atI their stood that the casing may be assembled in e i any desired manner, with a headlight of any. e! construction. 'f

The casing includes a front wall .Land a M rear wall 2, spaced slightly apart'.- lrotrading from the wall lis' the front lens .e hood 3, and protruding from the rear wall -ff 2, is the rear lens hood 4. At their up )er and lower ends, the walls 1 and 2 are rolled (553 outwardly, as denoted b v the numeral 5, and 4 filling strips ti are inserted into these rolled 'i-j portions. The walls l and 2 ar'e maintained i Si apart by means of spacing pieces '--which 1..,.ii are introduced between the walls` adjacent. ffo'` their edges. These spacing pieces T. as seen i" H most clearly in 2,: diverge'asthey extend upwardly, so that, while the-.lower 11S it; edges of the walls l and 'ares relatively L near together'. the said walls, attheix: uppcrjsi-f edgei, are spaced apart at considerable 'die` FI tance; say, t-wice the distance at which they.; are spaced apart4 at their lower edges. The walls 1 and 2 may he connected with the spacing pieces T in any desired mannerthe si) rivets 8 will be sullicient to thisendf. c'

Secured to the upper portion?) of the. rear f wall 2 is a rectangular spring strip t), seen most clearly in Fig. .Je of the'drawingsQand of smiieientJ length to extend entirely acrosslsl the casing. One arm of this spring strip t) upper edges, the spring strip J heilig adapt# I i` je ed to press against. the rear faces" ot' a p urality of transparentl plate's 1t), inclosed bei9'0l tween the front 'all l and the rear wall 2, i f these plates constituting what for conven-V ience may be denominated the lens portion of the device. Owing to the diver-ging relation of the walls l and 2, spac'e is provided 9'5 between them, at their upper ends, for tltci insertion of the spring strip 9 which bears .Y against the plates 10. f'f '.[he lower ends of the platesll() rest upon a supporting bar 1l. This supporting bar 1 00; L1 is mounted in placel between the lower ends of the walls 1 and the length of the support-ing bar 11 being somewhat less thim-y n the width of the casing between the spacingr pieces i". By this construction, openings 12 105 exist at the ends of the sup orting bar 1,1, whereb) dirt. and pieces o `broken glass, will readily sift outl ofthe easing. The sup-l portingr bar ll may be. held in place between the walls l and 2 by means of bolts and 110 thumb nuts 14, extended through the rolled come a part. It is therefore to be underl portions 5 located at the lower ends of the is secured to the supporting bar 1l, one g arm of this finger strip outstanding beyond Vthe face of the casing. that the support ing bar may readily be removed from the position in which it is normally mounted.

Secured to the front well 1 of the casing are brackets 16 and 17. These brackets may be provided with depending legs 3i', the same being riveted or-otherwise secured to the front wall 1. Located between the walls 1 and 2, at one side of the casing, is an arcuate spring stri) 38, the upper end 3i) of which is secure between the bracket l? and the upper end ofthe casing. This spring 38 bears a ainst the edge of one of the plates 10, an( serves to maintain the adjacent edges of the several plates 10 in contact with each other. Thus, through the instrumen tality of the s rings 38 and 9, the several plates 10 will held yieldably in place, so

that, under the heat of the iam these lates A miy expand both transversey and ongltu inally, without dan er of breakin The brackets 16 an 17 are provided at their forward edges, with the de ending lugs 18 in which are openings 19, at apted to reive the ends of a rod 20, connected with one edge of n trough shaped `lid or closure 21; thus, the lid 21 1s pivotally mounted, the same being adapted to extend over the top of the casing to serve as a closure therefor, the lid being held in closed position by means of a lug and spring catch device 22, connected with the upper portion of the rear wall 2.

In the upper ed e of the bracket 1T there iS s notch 23, whl e in the bracket 16 there is a circular opening 2l. 'l'hese elements 23 and. 24 are adapted to receive rotatably, the spinules 25 in the ends of a shaft Q6, upon which is wound a. curtain 27. At this point it may profitably be stated that the lid y21 serves to shield the shaft 26 and a portion ol the curtain27 which is rolled thereon, and likewise to prevent the spindle 2.3 which is mounted in the notch 2i-l, from heilig disenged from the bracket 17. lilorcover, the

l id, extending over the upper ends of the several plates 10, serves to mixinlain llal said plates in place, preventing,r them from being dis Jlaced, upwardly.

,ocated upon thel front wall l below the front lens hood 3, is a pulley 28 of any de- Sircd construction. Smtahly disposed upon thc front wall l adjacent line pulley is u hook 2f). Upon tho lowcr'end of llnI curtain 2'." there is a ring im, lo which is .secured onecnd of a cord 3l, the interna-liuto poi'- tion of thccord 3l beingr carried anti-friotionally in thc pulley IS, the ring :so boing :adapted to Le engaged hy lh'- hook 2S), lo holdV the curtain .T m l'ronl ol Ilnleus portion of the deviner, the curtain livin-g nor- 65 mallxi held in rolled up position hy nn-au ol' sired, one end of a flexible element 33 may bei wound about a s ooi 100 upon one of the spindles' 25, the ot 1er end of the flexible element being connected with the upper end of a retractile spring 34, the lower end of which is secured by a'hook and eye coniiection as at 35, or in any desired manner, to the front wall 1 of the casing. When this expedient is resorted to, both of the s indles are rotatably mounted in thebrac ets 16 and 1T. Sometimes, however, the spring 34 is dis ensed with, and a common, spring actuatedJ roller of the Hartshorne type is used. In such instance,'the squared end 3G of the spring actuated curtain roller is held against rotation in the notch 23 of the bracket 17, as shown in Fig.

The operation of the device will probably be clear from the foregoing description, but it may be stated briefly at this place that by. manipulatinfr the cord 31, the curtain 2T may readilyx: drawn. downwardl in front of the lens portion of the device, t e curtain being maintained in position, either by securing the extremity of the cord 31, or by hooking the ring 30 over the member 29. Owing to the presence of the resilient members 38 and 9, the several plates 10 will be yieldably held, so that they may expand and contract without danger of breakage. By removing the supporting bar 11 one or more of the plates 10 may be replaced; or by swinging the lid 21 forwardly, the/'plates 10 may be removed from the top of the device. Owing to the fact that there are openings at the ends of the supporting bar the dust and dirt within the casing may readily lind its way out of the same'.

'lhc lid 2l serves to protect the interie. I

of the easing, to protect the rolled up portion of the curtain 2i', to rolect the upper ends of thc platos lll andpto limit tho upward movi-ment, both of the plates 10 and of the spindle which is mounted in lhc slot Q3 of the bracket-1T.

Although hul, one of the spindles 25 is shown in hier. l. the other spindle Q5 need not he specifically shown, since it is simply a project ing eli-nient upon the end of the shaft 2G, rotatably mounted in the opt-ning Q4 in llnI hrm-iwi, lli; the construction being common and well known. 'lhc lowurt-nds ofthe plains l0 :irl: retained lit-tween the lower. vndr; of (lne walls l and "J, whihe thc spring il .sierva-5'.. af horrinlnzl'unpointed mit., lo press againsty and to hold the upper ends -of the plates.

Having thus deseribed the invention, what is claimed is:

1. In a deviee of the class described, an

open top casing; brackets earried by the eas# ing adjaeent its ton: a shaft carried by thel brackets and retnesable through the upper edge of one ofthe ln'aekets; a curtain wound upon the shaft: n transparent plate mounted in the casing: und a closure for the top of the casing. the closure constitutingr at onee a shield for the Curtain and a means for holding both the plate and the shaft against displacement.
