UNITED STATES PATENT OFFICE EMERGENCY ROAD SIGNAL Harry Bernstein, Elizabeth, N. J. Application August 12, 1947, Serial No. 768,220

3 Claims. (01. 177-329) The present invention relates to highway and roadside caution and warning signals adapted to be used by automobile, truck and equivalent drivers on or within the vicinity of the vehicle and in a manner to warn drivers of other nearby cars to steer clear of the danger area, whereby to thus assist in minimizing highway accidents.

As the introductory statement of the invention implies, I am aware that the art to which the invention relates comprehends the provision and use of various types of signalling devices characterized by illuminable lamps, caution flags, and

the like. It follows that the instant invention appertains to a structure which, it is submitted, is possessed of appreciable refinements and improvements and thereby constitutes a different and Worthy contribution to this line of endeavor.

In carrying out the principles of the present invention, I provide a portable chest-type signalling device, the accessories and parts being mounted in the chest proper and being exposed for use when the lid is swung to open position, said lid being supported in a vertical position and serving to display the word Danger.

In keeping with my inventive ideas, I provide a pair of companion warning flags, the staff portions of same being mounted on novel, springequipped fixtures, whereby, when the lid is open, the flags swing out to ready-to-use display positions.

Another object of the invention is to provide a self-contained source of illumination for a pair of lens-covered lamp bulbs, this phase of the invention having to do with a dry cell battery, an intermittent flasher for the lamp bulb, a three-pole switch, and a complemental receptacle which may be used to accommodate a trouble light, if and when it becomes necessary to use the latter.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings:

Figure 1 is a perspective view of the emergency signalling device constructed in accordance with the principles of the present invention, the same being shown when not in use;

Figure 2 is a perspective view of the same illustrating the arrangement of principal parts when the device is in use;

Figure 3 is a transverse vertical sectional and elevational view on an enlarged scale;

Figure 4 is a sectional and elevational view of a fragmentary type'detailing the construction of one of the flag stafis;

Figure 5 is a perspective view of the special fixture which is used for hingedly mounting the lower end of one flag staff Figure 6 is a fragmentary perspective view of one of the details; and

Figure '7 is a wiring diagram.

Referring now to the drawings by distinguishing numerals and their lead lines, the box or chest proper, which is of appropriate material of suitable strength and weight, is denoted by the numeral 9 and the hingedly mounted cover or lid is denoted at Ill. The lid is provided with stays H for holding same in a vertical position when in use, as shown in Figure 2. Appropriate latch or locking means I2 'is provided to keep the lid closed when the device is not in use. As seen in Figure 3, a horizontal partition I 3 is mounted in the upper rear half portion of the chest on a plane below the opentop of said chest. In addition, an adapter type'insert I4 is mounted in the space between the partition and the front panel l5, as shown in Figure 3. Said front'panel I5 is provided with apertures to accommodateinteriorly arranged reflectors l6, and lenses H. The lenses are preferably colored red for caution purposes. Each reflector is provided with a socket Hi to accommodate an appropriate lamp bulb l9.

Warning flags 20 and 2| are provided, as before indicated, and these are mounted on the partition l3 in the manner shown. That is to say, the flags are alternately arranged and mounted adjacent opposite ends of said partition so that they may be folded into the chest beneath the lid, as seen in Figure 3, when not in use. When the lid is swung open, the flags swing out to display positions, as is obvious. Each flag is the same in construction and the description of one will suffice for both; To this end, attention is directed to Figure 5 wherein one of the attachment fixtures 22 is shown. This comprises a base plate 23 with an upstanding channel-shaped mount 24, the latter serving to accommodate a hinge pin 25 on which the inner section of the flag staff, the section 26, is mounted Spring means is provided for swinging the staff out and holding it in an outstanding position. The spring is of general U-shaped form and the bight portion 2! is saddled over the hinged end portion of the staff 26. The limbs 28 rest on the base plate and the intermediate portions of the limbs are coiled around the hinge pin 25, as indicated at 29. Thus, sufficient tension is brought to bear on the staff to swing it out, or to permit same to be swung, by hand, down and into the box to assume an outof-the-way position when not in use. Each flag stall includes a sleeve section 3ll (see Fig. 4) having a head 3| on its outer end, the sleeve being telescopically mounted on the staff section 26 and having appropriate indentations forming friction detents 32. This permits the flag proper, 33, to be raised to a desired elevation.

The insert M has an elongated receptacle portion 34 which provides a pocket for an extension cord 35. This cord is provided with an attachment plug 36 which may be hooked into the electrical system of an automobile. It may be inserted, for example, in the customary cigarette lighter circuit on the instrument panel of the automobile (not shown). Of course, the part 3.6 may be of suitable construction to permit it to be clipped on a storage battery or otherwise hooked into the lighting system. This .cord .35 serves to supply current to a suitable receptacle 3? at one end of the part M, as shown in-Figure 2. Obviously, the receptacle 3'! serves to accommodate a plug such as is usually provided on a trouble light (not shown). It is sometimes necessary to use a trouble light, particularly if the storage battery of the adjacent automobile is out of order, and it is therefore one of the purposes of this invention to supply the receptacle 3! with current not only from the cord 35 but also-from the interior of the chest. This is accomplished by providing a dry cell 38 on the interior, as shown in Figure 3, and running wires 39 and 40 therefrom to said receptacle. At the end of the part I4 opposite to the receptacle 3'! a three-pole switch 4| is provided, this having an appropriate selector and control button 42. The wire 40 is connected with the switch as shown in Figure 3. An additional wire 43 is connected with the dry cell and switch and complemental wires 44 and 45 are provided for supplying current to the lamps, preferably by way of a conventional type flasher 46 and an accommodation wire 41. The flasher is mounted in an appropriate bracket 48.

It is obvious that the switch means may be utilized and thrown in to energize the flasher means and bulbs from the self-contained dry cell battery 38. If the dry cell battery is dead and an electrical sourceis available on the nearby automobile, then the cord 35 and means 36 may be brought into play to supply current from the latter source to the receptacle '3'! and alsoto the bulbs or lamps [9.

Obviously, I am not especiallyconcerned in this mechanical case with the electrical phases, but, as shown in the wiring diagram in'Figure 7, such as may be employed if desired.

I am primarily concerned with the portable, weighted self-standing chest, lamp means, flag means, trouble light accommodating receptacle means, and the incidental complemental parts. For example, in practice, I will provide the lid with a carrying handle 49 and also, on the interior of the lid, will provide further signalling means 50. This has to do with the word Danger, which is painted on the underside of the lid using said underside as a display panel. Luminous paint may be employed for lettering the sign.

The invention shown and described constitutes a handy and aptly usable accessory which may be brought into play when emergency requirements on highways are met.

The manner of use and operation of parts will be self-evident, for which reason a description of same is thought to be not required.

In view of the foregoing description taken in conjunction with the accompanying drawings, it

is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and Within the scope of the appended claims.

Having described the invention, what is claimed as-new is:
