TRAFFIC CONTROL SIGNAL Filed Nov. 26, 1965 Hlberi" H.Bohren5r.

BY INVENTOR United States Patent 3,435,412 TRAFFIC CONTROL SIGNAL Albert H. Bohrer, Sr., 11104 NE. Wygant, Portland, Oreg. 97220 Filed Nov. 26, 1965, Ser. No. 510,003 Int. Cl. B60q N00 US. Cl. 340-107 Claims ABSTRACT OF THE DISCLOSURE This invention relates to traffic control signals of the class which are manually held and operated.

It is the general purpose of the present invention to provide a manual traific control signal having two separate signal faces, which is reversible to display and actuate the selected signal face as desired.

Another principal object of the invention is the provision of a trafiic control signal which may be carried in the hand, or set in a stationary base at the election of the operator.

Still a further object of the invention is the provision of a portable traflic control signal which is electrically operated through a rechargeable dry cell battery system.

In the drawings:

FIG. 1 is a view in front elevation, partly broken away to show the interior construction of the reversible trafiic control signal of my invention;

FIG. 2 is a fragmentary view in side elevation, partly in section, of the signal;

FIG. 3 is a fragmentary sectional view taken along lines 3-3 of FIG. 1 and illustrating the manner of assembly of the components of the signal; and

FIG. 4 is a schematic view of a charging element which may be used in conjunction with the signal.

Generally stated, the reversible traflic control signal of my invention comprises an elongated hollow handle dimensioned to contain one or more dry cell batteries. An electric circuit is mounted within the handle and includes, in addition to the batteries, two electric contact pairs accessible side by side on one of the handle ends, a threeposition electric switch, and electrical conductors interconnecting the lforegoing elements so as to form two subcircuits each including one of the contact pairs, the subcircuits being alternately energizable through the switch.

A signal head is mounted on the handle. It comprises an outer case of transparent material bearing trafiic control indicia on each of its sides as well as an opaque central shield dividing it into two compartments which are lightshielded from each other.

An electric circuit is mounted in the signal head. It includes a pair of electric lights mounted one on each side of the shield, two electric contact pairs accessible side by side on one end of the case and releasably engageable with the contact pairs of the handle, and electric conductors interconnecting the lights and the contact pairs to form two sub-circuits each including one of the contact pairs. Each of the sub-circuits is separately energizable through the corresponding sub-circuit of the handle to which it is connected.

3,435,412 Patented Mar. 25, 1969 Suitable battery recharging means, as a rectifier of gmall size, may be mounted in either the handle or signal ead.

Accordingly, in use, the three-way switch may be activated to energize one or the other of the sub-circuits, thereby illuminating the light behind the selected one of the trafiic control indicia. The sign may be reversed as required to display the message on its other race. It may be held manually or placed on a suitable support. When desired, it may be recharged by inserting the electrical contact terminals in the wall plug of the conventional volt house circuit.

Considering the foregoing in greater detail and with particular reference to the drawings:

The reversible, manually operated, trafiic control signal of my invention basically comprises a handle section by means of which the sign is held, manipulated and operated, and a releasable head section electrically connected to the handle section and carrying a suitable trafiic control message on each of its sides.

As shown in the drawings, the handle section, indicated generally at 10, comprises an elongated tubular case 11 dimensioned to receive a plurality of conventional dry cell batteries 12. A three position switch 14 is mounted on the case convenient to the thumb of the operator. A separable base member 16 is dimensioned to slip over the bottom end of the handle.

Handle 10 also mounts two electric contact pairs accessible side by side on the upper end of the handle. These may comprise either the male or female members of plug-in electrical connections. In the illustrated form of the invention they comprise prong-type electrical contact elements 18, 20.

Handle 10 also mounts electrical conductors suitably arranged to include the electrical contact pairs in two sub-circuits, each including one of the contact pairs and each being separately and alternately energizable through switch 14.

The signal head, indicated generally at 22, basically comprises an outer case of transparent material bearing traffic control indicia on each of its opposite sides, an opaque central shield dividing the case into two compartments, and a suitable electric circuit to illuminate the space in each of the compartments separately and alternately.

In the form of the invention shown in the drawings, the case is formed in two matching halves 24 of suitable outline, as octagonal, each having a convex central portion as well as a marginal flange by means of which it is joined to the companion case section with bolts 26. The lower end of each of the case sections is formed with a semi-circular housing 28 which, in the assembled form of the signal, houses the unit by means of which the head is coupled to the handle.

The component sections of case 22 may be made of various transparent materials. Preferably they may be fabricated from transparent plastic, colored and shaded as desired. Each may bear indicia conveying an appropriate message. For example, if the sign is to be used on a construction project, one of the sides may bear the word Stop and the other the word Slow with the thought in mind that the sign operator may display whichever side of the sign is appropriate.

In the illustrated form of the invention the shield member indicated at 30 serves the multiple purposes of preventing the transmission of light from one compartment to the other; of serving as a support for mounting electrical lights 32, one in each compartment; and of serving as an electical connector through which the lights are grounded. Still further, it may serve as a light reflecting surface which intensifies the brilliance with which the signal is emitted.

Accordingly the shield may comprise a plate codimensional with case sections 24 and secured in intermediate assembled relation thereto by means of bolts 36. The plate preferably is made from a suitable electrical conducting material, such as a conducting metal sheet having a shiny surface.

Housing components 28 of case sections 24 receive an electrical socket member 34. This member is made in two sections of electrical insulation material and is secured to plate 30 by means of bolts 36.

Socket member 34 provides two pairs of electric contact members and in addition provides fastening means for fastening the signal head to the handle. The contact members include receptacles 38, one on each side, Which receive contact prongs 18. They also include a projecting end of electrically conducting plate 30 which extends into a recess 40, dividing it into two parts, each of which is dimensioned to receive one of contact prongs 20.

Each of contact elements 38 is electrically connected to one of lights 32, thereby providing two sub-circuits in the signal head, each of which includes one of the contact pairs and one of the lights, and each of which separately is energizable through the corresponding subcircuits of the handle to which it is connected.

Preferably, though optionally, the signal of the invention is provided with a battery charging unit comprising a conventional rectifier 42 having sockets 44, 46 dimensioned to receive prongs 18, 20 respectively. The rectifier is attachable to the house line by a plug 48. It may be provided as a separate unit or built integrally into handle 10.

It thus will be apparent that by the present invention 1 have provided a traflic control signal which is manually operated and reversible to display a selected message. The selection may be made conveniently by manipulation of three-position switch 14 to energize one or the other of lights 32. The signal may be held in the hand or, if desired, stationed in Stand 16 at a location, somewhat removed from the danger site. When necessary, the battery may be recharged by means of charging unit 42.
