Abstract: A traffic control device, such as a traffic signal light housing, with a resiliently deformable back plate assembly. The backplate assembly comprises side flanges that bend or deform in response to external forces such as high winds and blowing debris. In one embodiment, rigid side flanges include a hinge or joint formed of an elastomeric material. This multi-directional wind-dampening backplate renders the housing more aerodynamic and benefits the entire signal structure, including mast arms, poles, and span wire systems.

Abstract: An articulating clamp assembly for traffic control assemblies that include luminaires. The clamp assembly includes first and second clamp members. The first clamp member includes a male tubular fitting for telescopically engaging a female fitting on the luminaire. The second clamp member is attachable to the end of a luminaire arm by a tenon sleeve, to the side of a pole with saddle plate, or to a simplex fitting with a simplex mounting bracket. The front ends of the first and second clamp members have inter-engaging serrated faces that allow adjustable engagement of the two clamp members to adjust the position of the luminaire. Each clamp member defines a continuous end-to-end conductor path, and the articulating ends are formed to create a continuous concealed conductor path through the joint. The tenon sleeve may include a U-bolt to secure it to the luminaire arm.

Abstract: A support tube assembly for use in mounting traffic signals and other traffic control devices. The tube has a standard 1.9 inch outer diameter with a wider three-quarter inch access slot and a larger internal volume to accommodate five-eighth inch conductors. The support tube assembly may include a secondary mounting assembly for attaching a second traffic control device. The secondary mounting assembly includes a mounting strip that fits inside the access slot and a mounting plate that attaches to the strip. Each edge of the access slot has a contoured profile that mates with the corresponding side on the mounting strip so, when the secondary mounting assembly is attached to the tube, the edges of the access slot are gripped between the back of the mounting plate and the inner mounting strip. A cut-to-fit vinyl closure strip is included to enclose the exposed sections of the access slot.

Abstract: An articulating clamp assembly for traffic control assemblies. The clamp assembly includes first and second clamp members. The first clamp member, or tube saddle, has a rear face designed for attachment to a bracket tube. The rear face of the second clamp member is attachable either to the end of a mast arm by a tenon sleeve or to the side of the mast arm by cables or bands. The front ends of the first and second clamp members have inter-engaging serrated faces that allow adjustable engagement of the two clamp members. Each clamp member defines a continuous end-to-end conductor path, and the articulating ends are formed to create a continuous and substantially straight conductor path through the joint in the assembled clamp. In this way, the path of a conductor from the mast arm to the bracket tube is substantially straight facilitating the installation of large diameter conductors.

Abstract: A pedestrian push button that discourages vandals and resists weather-related damage. The plunger is contained in a sleek, solid housing formed by a cup-shaped front cover that overlaps and substantially encloses a shallower, cup-shaped body, to protect the electrical components inside. The body is attachable from the inside to the traffic pole or other support surface, and the cover engages the body by means of a “twist-lock” connection that is hidden from view in the installed device. This reduces the appeal of the push button to vandals while at the same time making it easier for authorized personnel to open the housing for service and repair. The back of the body is contoured to conform to both flat and curved support surfaces, making the push button easy to mount securely regardless of the shape of the support surface.

Abstract: A span wire assembly for supporting a traffic control device. The span wire assembly includes a pair of vertical members or cast arms for attachment to the traffic control device. The cast arms are integrally formed with tubular ends and a centrally positioned wiring passage. A span wire assembly utilizing the inventive cast arms has fewer parts and, consequently, is simpler for the manufacturer to produce and for the customer to use.

Abstract: An articulating clamp assembly for attaching a traffic control device to a mast arm upright pole or other support member. The clamp assembly includes a saddle clamp which adjustably attaches to the vertical elongate member on the bracket of a traffic signal. Either a cable clamp or a tenon clamp can be included for attaching the assembly to the mast arm or pole. The cable clamp includes inner and outer tubular members which are rotatable relative to each other, and of course the anchor plate of the cable clamp can be positioned anywhere along the length of the mast arm or pole and anywhere around the circumference. Similarly, the tubular end of the tenon clamp can rotated relative to the mast arm for proper positioning. The mast arm clamp and the saddle clamp are joined by a pair of serrated rings which permit a wide range of rotational adjustment between the two clamp members. Thus, the articulating clamp assembly of the present invention permits multiple adjustments.
