Application June 2,
5 Claims.
Our invention relates to spot. lamps and has particular reference to the type of spot lamps employed on police cars for thepurpcse of in-,
speeds through traffic to arrive at the scene of the emergency, or for the purpose of pursuing lawbreakers through trafilc.
In order to warn other vehicles to give the right of way to such police cars, it is the common practice in many localities to provide such police cars with a characteristic spot lighter signal lamp which when illuminated produces a distinctive color, warning all persons viewing the same that the vehicle carrying such lamp is a police car and must have the right of way over ordinary traflic.
However, if such lamp is employed normally in view the car may be located or spotted by criminals and lawbrakers at a suffioient distance away to permit them to escape. In other words, the criminal looks for a spot lamp of this charactor as a means of identifying the police vehicle, thereby reducing the chances of the police to apprehend the criminals.
Even when such lamps are extinguished, the lamp itself, being visible to persons looking at the car, will give knowledge of the fact that .such vehicle is a police car and in many instances this warning or preknowledge permits the escape of criminals who might be apprehended were it not for the visible position or the distinctive spot lamp.
It is, therefore, an object of our invention to provide a spot lamp of the character set forth in the preceding paragraphs, wherein the same may be normally concealed from view and may be moved into position to exhibit its characteristic warning indication when such indication is desired.
Another object of the invention is to provide a spot lamp of the character set forth with an automatic switch mechanism which causes the lamp to become illuminated whenever it is moved I into visible position.
Another object of our invention is to provide a simple mounting means for a spot lamp of the character setforth wherein the lamp may be mounted inside the vehicle in a position normally out of view oipersons observing the car and which may be moved from such position to a second position at which the .lamp will project its characteristic li ht through the windshield of the vehicle carrying the same.
1936, Serial No, 83,084
Another object of our invention is to provide a lamp of the character set forth the preceding paragraphs, wherein an automatic switching arrangeinent is employed to cause illumination of the lamp whenever it is moved to the position projecting its rays through the windshield.
Other objects and advantages will be apparent from a study of the following specifications, read in connection with the'accornpanying drawing, wherein Figure l. is a diagrammatic view, illustrating the sectional view of the top of an automobile with our lamp mounted in place therein;
Figure 2 detail enlarged view of the lamp shown in 1, illustrating the mounting and the switching mechanism employed; and
Figure 3 is a detail, perspective view oia form of contact piece which be employed in the switc ing mechanism shown in Fig. 2.
Referring to the drawing, we have illustrated in Fig. a spot lamp 5 which may be of any suitable size and shape, preferably being constr .cted with a handle section 2 formed integrally therewith whereby the lamp may be moved to its various positions.
While the lamp structure itself may be of any desired shape or construction, suchdevices or dinariiy include the outer cas. i within which is mounted a suitable reflector d and through which projects a socket carrying a lamp 5. The front end of the casing l is closed with a suitable lens ii which may be colored red, amber, or any other suitable color selected by the police departrnent as a particular designation of police vehicles.
The larnpcasing i preferably provided with an outwardly extending l by which the lamp may be secured to a suitable supporting bracket bracket 3 y oi any desired shape adapting it to be so ured as by means of screws Q to some portion of the body structure oi the vehicle as, for example, the tc rail iii of the windshield ll of the vehicle, as illustrated in l. The bracket arm of bracket ii is preferably bent rearwardly, indicated at it, and is formed with split or bifurcated end it constituting one-half of a hinge or pivot connection between the bracket s and the arm 5. The arm l rigidly secured thereto a shaft M which projects through the hinge section iii of the bracket 3 permitting the l to be from the full line position, illust d in Figures 1 and 2 to the dotted line posit illustrated therein.
With the construction thus far des oed, it will be. apparent that the may normally swung to the lull-line position, as she Ill in the drawing, in which posit on it will be "-antially out of sight of persons viewing the vehicle while whenever it is desired to actively employ the lamp it will be swung to its dotted line position lvl at the rear of the windshield II, in which position it will be adapted to project its illumination through the windshield to give the necessary or desired warning that such vehicle is a police vehicle and has the right-of-way over other vehicles.
In order to facilitate the operation of the lamp, suitable switching mechanism for automatically illuminating the lamp whenever it is swung to its active position should be provided. This may be'readily accomplished, as is illustrated herein, by providing upon the shaft [4 a disc or drum it: of insulating material having on its periphery a short contact segment It formed of metal. The drum I5 is rigidly secured by means of a screw l l to the shaft 1 4 and will rotate with the shaft whenever the lamp is moved from one of its positions to the other.
A complementary contact member I8 is preferably mounted upon the bracket 8, this contact member being illustrated particularly in Figure 3 as including a socket l9 which may be formed from a strip of metal rolled upon itself, one end 20 of which extends outwardly to provide a means of attaching the same to the bracket, as by means of an opening or hole 2i through which a screw 2 l a may pass to engage the bracket 8. The socket !9 is preferably provided with a reduced lower end located at 22 through which projects the reduced section of a metal contact pin or brush 23, the brush 23 being normally urged outwardly of the socket ill by means of a spring 24 bearing against an adjusting screw 25 screwed into the upper end of the socket l9.
As is illustrated particularly in Fig. 2 the location of the contact strip IE on the drum I5 is such that whenever the lamp is in its concealed or full-line position the brush 23 will bear upon an insulated portion of the drum, while when the lamp is moved down to its dotted line position, or its active position, the brush 23 will bear upon the metal contact piece l6.
By connecting the socket 4 in a suitable electric circuit which extends from the battery of the automobile by way of a conductor 26 to the socket 4 and from the socket 4 by way of conductor 21, the conductor 2'! may be connected to the contact strip I6 so that the circuit for illuminating the lamp will be completed whenever the contact piece I 6 engages the metal brush 23,
grounding the contact piece Hi and thereby providing a ground return to the automobile battery.
In order to insure that the lamp when moved to its active position will stop at the most desirable location for it to project its beams through the windshield, I prefer to provide an adjustable stop upon the bracket 8, such stop being illus trated herein as including an auxiliary bracket arm 23 secured as at 29 to the main bracket 8 and disposed in such position relative to the arm 7 that a screw 30 passing through the auxiliary bracket 28 will abut the arm 1 when the lamp is moved into its active position.
By properly adjusting the screw 33, the movement of the lamp may be stopped at any desired position and a suitable locknut 3! may be employed to fix or hold the screw 30 in its adjusted position.
It will be observed that the construction herein described provides a simple means whereby a police warning lamp may be mounted upon a police vehicle in a position which is normally concealed from observers, but which, when emergenflies arise, may be swung into active position to project its light exteriorly of the vehicle to give the desired warning and also, at the movement of the lamp from its inactive position to its active position automatically illuminate the lamp only 7 at such times as the lamp has been moved from its concealed. position.
While we have shown and described the preferred embodiment of our invention, we do not wish to 'be limited to any of the details of construction shown herein, except as defined in the appended claims.
We claim:
1. In a concealable spot lamp for police cars;
a spot lamp, hinge means for mounting said lamp upon the interior of said vehicle for movement from a concealed position to an active position at which the lamp may project its light exteriorly of the vehicle, and means for automatically illuminating said lamp when said lamp is moved to its active position.
