Referring now to Figs. 1 to 6 inclusive, in 15 which corresponding parts’are indicated by the same reference ’charactersI ’ I6 indicates a casing member formed of sheet’ metal having a plurality _of openings I6 in its front face, in the arrange-* ment shown the casing member being pressed into 20 form out of sheet metal. Immediately in rear of the front wall of the casing member I5, I have provided a. pad I1 of sponge rubber provided with a plurality of openings I8 therethrough in posi tions corresponding to those of the openings I6 in the front face of the housing memberlä. In It is another object of my the openings I8 of the pad I1, I have provided a invention to provide an improved combination'of series of substantially spherical lenses I9, such . cost ofthe article. lenses I9 being of substantially greater size than that of the openings I8 whereby it is necessary só to stretch the rubber about the openings >some what for the insertion of the lenses into position. even if the housing may be distorted from its The pad I1 is preferably molded complete with original condition, and which maybe relied upon the openings i9 therethrough.` 'I'he lenses I9 are preferably formed of'glass 35 35 for keeping `out moisture under any and all of the desired color, being formed originally of weather conditions. ‘ substantially spherical form and being then given It is] another object of my invention to im prove devices of this type in sundry details here- ` a high polish by well-known methods, which can inafter pointed out.

In rear of the spacer member 2|, I have provided a re flector 24 which in the construction illustrated is in the form of a disc of polished aluminum or 10 chromium having forwardly concaved portions 25 arranged about the face ofthe member in positions corresponding to the positions of the lenses I 9. The curvature of the concaved por tions 25 and the effectiveV thickness of the spacer 15 member 2| are such that the concaved portions are concentric with respect to the spherical lenses I9. For holding the spacer member 2| and the reflector 24 in position with respectv to each other, I have provided lugs 25 on the plate 2|) 20 which extend through suitable openings 21 and 28 in the spacer member and the reflector for preventing any substantial relative movement between the parts. In the casing I5 in rear of the reiiector 24, I 25 have provided a pad 29 of sponge rubber of such thickness that it normally extends some little distance beyond the rear face of the casing mem ber I5. In rear of the pad 29, I have provided a sheet 30 of rubber and a metal plate 3| which 30 are held in position with respect to the casing member I5 by means of a flange 32 carried by the casing member, the flange 32 being connect ed with the plate 3| by means of rivets 33 which in the arrangement shown are in the form of integrally formed grommets. The arrangement 35 is such that when the back plate 3| is pressed into closure position the marginal portion of the sheet 30 acts as a gasket for providing a moisture-tight closure of the rear face portion 40 of the housing or casing. The pad 29 is alsol substantially compressed so as to apply sub stantial pressure forwardly upon the reñector 24, the spacing member 2 I, and the plate 20 so as to bring the plate 20 into tight engagement with the rear face portions of the lenses I9, whereby the pad I1 is compressed forwardly in addition to the compression produced laterally by the in sertion of the lenses I 9. The result is that an effective moisture-tight closure is produced be 50 tween the front wall of the casing and the lenses I9. ' With the lenses I9 of highly accurate spheri Figs. 'l to 1l, 34 indicates a casing member similar to the casing member I5 having openings 35 in its front face. Immediately in rear of the front wall of the housing or casing member 34, I have provided a sheet of rubber 36 provided with open ings 31 therethrough corresponding in position to'the positions of the openings 35 in the front wall of the casing member, such openings 31 be ing of considerably smaller size, however, than that of the openings 35. In rear of the sheet of 10 rubber 36, I have provided a plurality of sub stantially spherical lenses 38 similar to the 'lenses I9 above described, the arrangement being such that when the forwardly tapered front portions of the lenses 38 are pressed forwardly so as to ex tend through said openings 35 and 31 into the position as shown in Fig. 8 the marginal portions of the sheet of rubber about the openings 31 are turned forwardly into the form` of flanges 39 which serve as resilient seats for the lenses 38 in the 20 openings 35. The arrangement is such that when the lenses 38 and the rubber member 36 are pressed forwardly a moisture-tight closure is ef fected between the lenses and the front wall. In rear of _the lenses 38, I have provided a plate 25 40 having openings 4I therethrough correspond ing in position to the position of the openings 35 in the front wall of the casing member. In rear of the plate 40, I have provided a reflector plate 42 which in the arrangement shown is formed 30 of aluminum and highly polished on its front face. As is clearly shown in Fig. 11, the plate 42 ls- pro vided with a series of forwardly concaved portions 43 corresponding in relative position to the posi tions of the lenses 38 so that the concaved portions 35 are adapted to fit over the rear end portions of the lenses. In rear of the reñector, I have pro vided a compressible pad 44 which inthe arrange ment shown is made of sponge rubber, the pad being of such thickness as normally to extend 40 backwardly out of the casing member~ 34. About the pad 44 on the rear face of an outwardly extending flange 45 of the housing or casing 34 I have provided a washer 46 of sheet rubber which is held in position by a back plate 41. As 45 will be readily understood, the pad 44 is com pressed substantially by the attachment of the back plate 41 in position. In the arrangement shown, the plate 41 is held in position by rivets 48 formed integrally with the flange 45 in the 60 form of grommets. As'wiil be readily appreciated from an exami cal form as produced~ upon a commercial basis nnation of my improved construction, the reflector rather than by a precision process, with the rear is held positively in backwardly spaced relation 55 *face portions of the lenses and the front face of the reflector protected against the presence of moisture', and with the reñector accurately formed and accurately positioned concentrically with respect `to the lenses, my device is highly 60 efñcient for the purpose for which it is provided. I have found in practice that a large proportion of the ray of light striking the front face of the reflector is returned to the source of light with only a fair degree of spreading of the ray such 65 as is desirable for making the device effective as a warning signal. My construction is such that to the lenses at all times, the arrangement being 55 such that one of the lenses and the reflector may be pushed backwardly together under heavy pres sure without changing the backwardly spaced re lation of the reflector with respect to the lenses, the resilient support for the reflector (the pad 60 29 or the pad 44 in the arrangement shown) being adapted to yield for permitting this result. Upon the removal of the backward pressure from `the lens, the resilient support serves to move the reflector' and the lenses quickly forward again 65 into normal position‘with respect to the casing. a. heavy blow can be applied to the lenses Without ~ If the backward movement of the parts with re ` breakage, the resilient mounting of the lenses spect to the casing has been such as temporarily being such as to cushion the blow and prevent substantial damage. , My improved device as above described is so arranged and so organized that the parts can be produced readily and cheaply, and the assembly can. be effected very r-apidly by unskilled labor. 75 Referring now to the construction shown in to destroy, the moisture-tight closure between the casing and the lenses, such moisture-tight clo 70 sure is promptly :e-established upon the return movement of the parts. It will be appreciated that the retainer plate 20 (or the retainer plate 40) which is of com paratively heavy sheet metal formation serves 75 . . 2,108,446 as a' reinforcement for the metal reiiector, ‘act , 3 ameter than that of the openings so as to be heid _ ing to prevent bending of the reflector when back-y - by the wall portion in position with the major ward pressure is applied upon one ‘or >more of portion >of the lens in rear of (said front wall por the lenses without a corresponding pressure upon tion, a comparatively' thick pad of yielding ma the remaining lenses. The arrangement is such that when the abnormal backward pressure is. relieved upon the lenses the parts are brought back to normal operative position withoutv dis tortion or disarrangement otherwise. A While I prefer to employ the form and ar rangement of parts as illustrated in my drawings 10 and asfabove described, it is to be understood' ~ that my invention ‘is not to be limited to such form and arrangement except so far as the claims 15 may be so ìlimited by the condition of the prior ' art.
