text: referring more particularly to the drawing by characters of reference , fig1 discloses a solar energized sign 10 employing a rack of solar cells 11 such as suitable photovoltaic means oriented with their focal axis parallel to incident rays 12 of sunlight . the sign may comprise one or more illuminable sides 13 , 13 &# 39 ; which contain the advertising media . although the sign is shown as comprising the sides 13 , 13 &# 39 ; formed in a u - shaped configuration mounted on a pair of ground supported posts 14 , 14 &# 39 ;, it may form any suitable geometrical configuration either elevated above the ground or supported on its surface and still fall within the scope of this invention . each side 13 , 13 &# 39 ; of the solar sign 10 is illuminated at night by one or more suitable electric lamps 15 mounted in fixtures 16 , 16 &# 39 ; as shown in fig1 . each lamp is energized by one or more 12 - volt batteries 17 connected in a parallel arrangement as shown in fig1 and 3 with the batteries mounted on a rack 18 comprises a plurality of vertically arranged shelves 19 . this rack may be then housed in a container , such as the cylindrical container 20 which may be buried in a vault 21 in the ground beneath or near the sign 10 . as noted the rack may be removed from the vault or placed therein by a suitable hoist . fig4 illustrates that one or more of the batteries 17 may be mounted on the sign between its sides 13 , 13 &# 39 ; upon a suitable shelf 22 forming a part of the sign . fig5 discloses a diagrammatic illustration of a wiring diagram for sign 10 wherein rack 11 of suitable solar cells is connected through a diode 23 across the terminals 17a and 17b of a bank of parallelly arranged 12 volt batteries 17 . terminals 17c and 17d of this bank of batteries are connected across a suitable high voltage converter 23 which connects the battery voltage to a suitable high voltage low current power supply necessary to illuminate one or more fluorescent lamps 24 connected in any series or parallel arrangement as well known in the art . fig6 illustrates that a suitable low voltage incondescent lamp 25 may be directly connected across the bank of batteries 17 through terminals a and b shown in fig5 if so desired for direct current lamp use . a suitable converter for converting the battery voltage to a suitable alternating voltage incandescent lamp use instead of the direct current use shown in fig6 is also intended to be within the scope of this invention . in order to more effectively implement the use of the solar signs disclosed herein , a switch 26 and timer 27 may be utilized as shown in fig5 . with these switching means the sign may be shut off at any time by switch 26 without affecting the charging of the battery or bank of batteries 17 . further , since the sign should be illuminated only during certain hours of a twenty four hour period , timer 27 may be set , as well known in the trade to illuminate the sign only when needed to conserve the energy of battery or batteries 17 . it should also be noted that switch 26 may also be actuated by solar or lack of solar illumination to control illumination of the signs . although but a few embodiments of the present invention have been illustrated and described , it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims .
