The of the casing. threaded outer terminal 35 of the bulb engages Figure 6 is a detail plan view of the battery ,the exposed wall, as shown in Figure 2. 5B

The circuit closer is provided with a loop 3T which forms a hinge barrel to receive the straight extension 26 of the wire 24. When the paddle is at its lowermost position in the casing the curved leg 3l of the circuit closer engages the bottom of the casing, as best shown in Figure 2 and holds the upright leg 21 rocked outwardly to disengage the extension 28 from the center contact 29 of the bulb and maintain the bulb extinguished. When the paddle is raised the lowermost leg 3l gravitates and rocks the upright leg 2T of the circuit closer to engage the extension 28 with the center contact of the bulb and energizes the bulb.

In operation, at night time, when the user wishes to read the map, which is of the strip type, the handle I9 is grasped and the paddle is raised upwardly. As it starts on its upward movement, the circuit closer immediately moves to circuit closing position to energize the bulb for illuminating the map from the rear side. The handle may be held at any desired position of its upward movement, to locate the bulb to intensely illuminate a localized point on the map so that it may be clearly and quickly rea'd through the Cellophane pane I6.

' From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation. Y

What is claimed is:

l. A day and night map comprising a casing adapted to carry a road map and provided in its front side with an opening through which the map is visible, a transparent panel extending across the opening, a paddle extending into the casing through a slot in the casing and located rearwardly of the map opening, a battery carried by the paddle, a flashlight bulb carried by @the paddle having its outer contact engaging the outer contact of the battery, and a pivoted circuit closer carried by the'paddle adapted to engage the casing and move to open circuit position with the center contact of the bulb when the paddle is in released position and adapted to move to circuit closing position with the center contact of the bulb when the paddle is moved outwardly through the casing to energize the bulb and illuminate the road map.

2. A day and night map comprising a casing adapted to carry a road map and provided in its front side with an opening through which the map is visible, a transparent panel extending across the opening, a paddle extending through a slot in the top of the casing and having a loop at its lower end, a flashlight bulb carried by the paddle having its outer contact in contact with the outer contact of the battery, a wire extending across the loop in contact with the center contact of the battery and having an extension extending longitudinally of the loop, an angular circuit closer pivoted on said extension and having an upright leg adapted to engage the center contact of the bulb in closed circuit position, said circuit closer having a lower arcuate leg adapted to engage the bottom of the casing when the paddle is in released position and hold the upright leg in open circuit position and adapted to gravitate and rock the upright leg to closed circuit position when the paddle is raised for energizing the bulb to illuminate the map.

3. A day and night map comprising a casing adapted to carry a road map and provided in its front side with an opening through which the map is visible, a paddle projecting into the casing through a slot in the casing and located rearwardly of said opening, there being slots in the sides of the paddle at the outer end thereof to engage a wall of said slot in the casing and hold the paddle in released position, a flashlight battery carried by the end of the paddle within the casing, a flashlight bulb carried by the paddle having its outer contact in engagement with the outer contact of the battery, and a pivoted circuit closer electrically connected to the center contact of the battery and adapted to be moved into circuit closing position with the center contact of the bulb to energize the bulb when the paddle is raised to illuminate the map, said circuit closer being adapted to contact the casing and be moved thereby to open circuit position, out of engagement with the center contact of the bulb when the paddle is in released position to maintain the bulb extinguished.
