This invention relates to reflectors oi the type adapted to be mounted on vehicles in order to reflect light from the headlight oi afollowing vehicle back to the driver of the latter, and one object thereof is the provision of certain useful improvements in reflectors of the multiple type. Such reflectors may also be mounted on stationary supports, as, for instance,"at curves in high- Ways and at dead ends of streets. The caslngs of the reflectors may be molded, cast, or otherwise formed in the shape of letters, numerals, gures, trade-marks, designs, etc.

A further object of the invention is the provision of such a reflector with means for varying .0 the distance between the lens and its mirror.

This adjustment means is necessary so as to accommodate graded groups of lenses with various focal lengths and still maintain a reector of very high optical eiiiciency. These variations are 2,-, due to physical or optical variations and are common in the manufacture of inexpensive lenses. It is further useful as the means of controlling the optical characteristics of the reector by controlling the angle of the returning rays so as 3g to meet specic optical requirements ot various.v

specilcatlons.

A still further object of the invention is to provide such a reilex reflector with a multiple casing having hermetically sealed units which can be manufacturedlvery inexpensively in various shapes, forms, and of various materials.

Another object of this invention is to provide a reflector having va high degree of optical eiilciency and at the same time having its cost of manufacture reduced to a minimum. 1

The above and other objects will-be made apparent in the description below.,in which char-4 acters of reference refer to like-named parts in the accompanying drawing, forming a part thereof. l

Referring brieiiy to the drawing:

Figure 1 is a plan view ot an assembled multiple reflector.

Figure 2 is a side view of Figure 1. y

Figure 3 is a cross-sectional view taken on the line3-3oi'Figure1. v

' Referring in detail to the drawingl the numeral I 0 represents the, face plate of a casing 4I provided withra peripheral ilange II.- At spacedapart positions, a number of identical tubular walls I2 project inward from the iront wall I 0, that portion of the face I0 which would come within the enclosure of each wall I2 being blanked out in the casting. or stampingnof the casing. Each wall I2 encloses a socket I3 having a round- 5 ed base I4 from which the cylindrical wall I5, of the same diameter as the base I4, extends upwardly. A peripheral shoulder I6 marks the division between the inner surface of the wall I2 and the wall I5. The entire casing, together with 10 the various features oi' the sockets I3, as above set forth, may be cast, stamped out, or otherwise formed of unitary construction.

A reflector element or mirror II having the back I8 whose concave surface is covered with a i6 suitable coating of material such as chromium plate, is provided with a cylindrical flange I9 which is adapted to ilt very snugly Within the wall I5, so that it may be forced into position at a predetermined distance from the seat I6. A glass sphere or lens 2li of any suitable color is mounted on the seat iormed by the shoulder I6. A soit rubber ring or gasket 44 is placed about the equatorial belt of the sphere 20 toserve as a water-proong packing to prevent moisture g5 from getting below the lens. After the mir-f ror Il, the lens 20,' and the gasket 44 have been mounted in the sockety I3, a plate 45, having a ,plurality of circular openings therein with each oi' these openings surrounded by an upwardly 30 and inwardly projecting frustro-conlcal lip 46, is set down against the iront face 42 of the wall I0, with each lip surrounding one of 'the lensesZiI. A peripheral ilange 43 surrounds the face 42, and this flange is then turned inward against the periphery of the plate 45, as shown at 41, to lock the plate 45 against the casing 4I. Other forms of 4lenses aside from spheres may be used with equal advantag No means for attaching the reflector on a vehicle or other support has been shown or described, as such means does not form any part oi' the present invention; obviously, any suitable means may be provided. It is also obvious that modiiications in' form and structure may be 45 made without departing from the spirit and scope oi the invention.
