Description

Patented Dec. 31, 1929 I UNITED STATES ROBERT EDELMANN, F NEW YORK, N. Y.

SIGNAL DEVICE Application led August 19, 1927.y Serial No. 213,990.

This invention relates to signal devices and more particularly such as are used on motor be attached to existing motor vehicles with-V out disturbing any of the conventional construction and capable of selectively indicating the intention of the driver of the vehicle ..15 equipped therewith. v

A further aim is in the provision of a novel means for illuminating` the indicating device to show a retarding of speed, a stop, a right turn, or a left turn.

which will become apparent as the description progresses, are attained by the unique construction, combination and arrangement of parts, hereinafter described and illustrated in the associated drawing, constituting an important component of this disclosure, and in which Figure 1 is a fragmentary,'perspective view of a conventional motor vehicle equipped so with an embodiment of this invention.

Figure 2 is a front elevational view of a signal device made in accordance with this invention.

Figure 3 is a similar view of the same having the front plate removed to show the wiring diagram.

Figure 4 is a transverse sectional view taken on line 4-4 of Figure 3.

Figure 5 is a similar view taken on line 5 5 of Figure 3.

In the drawing, the numeral 10 generally designates a conventional motor vehicle on the side of which, adjacent the drivers seat, is fixed a bracket 11 carrying a casing 12.

The casing consists of a pair of transparent circular plates 13 on which are marked by any preferred method, a double pointed arrow 14 and the word Stop 15.

The plates are held together by a pair of These several ob] ects, together with others,`

bands 16 around the rims thereof and are spaced by an annular band 17.

Formed in the casing are a plurality of

compartments

16, 18, 19, 20, 21, 22, 23, and 24, in which are respectively mounted

bulbs

25, ,55 2e, 27, 2s, 29, so and e1.

The

vbulbs

25, 27, 28' and 30' eachhave one pole 32 thereof mounted in an insulating block 33 fixed to the inner wall of the respective compartments by a screw 34, the opposite pole 35 engaging a spring 36 mounted in a socket 37 secured to the band 17, the latter forming a ground.

The inner poles of the

bulb

25 and 27 areconnected by an electric conductor 38, which in turn is connected by a wire 39 to a switch arm 40 -engageable with a contact 41 connect-ed to one end of an electric battery 42, the opposite end of which is grounded.

The innerpoles of the

bulbs

28 and 30 are '70 connected by a conductor 43 which in turn is connected to a wire 44 leading to a switch arm 45 engageabl'e with the contact 46, also Aconnected to a source of current 42.

Fixed to the band 17 in the compartments 275 19, 22 and 24 are brackets 47 carrying the

bulbs

26, 29 and 31, one pole of each bulb being connected through the bracket to the ground band 17. y

The lower poles of the bulb 26"and 29 arefgg connected by a conductor 48 in contact-with a wire 49 attached to a switch arm 50 engageable with contact 51 leading to the source of current 42 and the lower pole of the bulb 31 is connected by a wire 52 to a"g5 switch arm 53 engageable with a contact 54,

' also leading to the source ofl current supply 42.

The

leads

39, 44 and 52 all pass downward through a tube 55 at the lowermost ypoint of'eo the casing 12.

Thus, if it is desired to indicate the intention of a retarding of the speed of the vehicle, the driver engages the switch arm 50l with the contact 51, completing the circuitb to illuminate the

bulbs

26 and 29, which will show through the plates A13 to make the central portion of the double pointed arrow 14 appear lit, indicatingdrivers intention to those in front or in the rearl olf the vehicle. 55100 By tracing the diagram shown in Figure 3, it will be also seen that by respectively closing the switches 40-41, Ll-l and 53-54, the lights 25-27, 28-3() or 31 will be illuminated to indicate a left or right turn or a stop, the saine being shown on the plate 13 by the illumination of either end of the doublepointed arrowvll or the Word Stop.

From the foregoing, it is obvious that many accidents may be avoided since it will be possible for a drivel' to know just what the next movement of the vehicle in front of him will be'.

While the foregoing is descriptive of the preferred embodiment of my invention in detail, it is not intended that the same be interpreted in a limiting sense, as changes in size, proportion, etc., may be made without departing from the spirit and scope of the appended spaced, a grounded band and sets of bulbs within said casing, insulated blocks having one pole of the bulbs of two sets (25, 27, and 28, 30) `mounted therein, grounded springs engaged by the other poles of said bulb sets, an

electric conductor connecting the inner polesv of the bulbs of one set (25, 27), a switch arm (40) connected to said conductor engageable with a contact connected with one pole of a source of electricity, having` its other pole grounded, a conductor connecting the inner poles of the other set of bulbs (28, 30), a second switch arm (45) connected to said conductor and engageable with a contact connected with a source of electricity, a third set of bulbs (26, 29,) having one pole thereof connected to said grounded band, a switch arm (50) to which the other poles of said set of bulbs are connected, said switch arm engageable with a contact connected to a source of electricity, and a single bulb (81) also connected at one pole to said grounded ring, partitions in said casing separating the same into a plurality of chambers, each containing one bulb of said sets of bulbs and one of said chamber the last named bulb to illuminate the word Stop, a switch arm (53) connected to the other pole of said single bulb, said switch arm connected to a contact in connection with a source of electricity, said switch arms adapted to close the circuits in which said set of bulbs and the single bulb is located to illuminate the word Stop and the double pointed arrow to indicate an intended stop, turns, and direction thereof and nature.
