Abstract: A tubular synthetic-resin body usable as a roadway marker comprises spaced upper and lower tubular parts interconnected by thin webs formed integrally with the upper and lower parts. A middle part of contrasting color lies between these upper and lower parts and has grooves receiving the connecting webs. Such a roadway marker is made by fitting the middle part over a core of a mold, and then injecting synthetic-resin material into the mold around this sleeve so as to form the upper and lower parts and the web.

Abstract: An emergency warning traffic sign comprises a conventional stop sign which has been divided vertically in the middle into two sheet portions carrying portions of the message on one face of each of the sheet portions. The sheet portions are connected by a hinge such that a first of the portions may be mounted to a traffic signal post and the second sheet portion may be rotated between a first position in which the message is obscured to a second open message position. A locking bar is attached to the first sheet portion and is pivotally movable across the back of the sign and within its perimeter to lock the sign in both its open and closed positions. In a second embodiment of the invention, another sign carrying a different message is also divided vertically into a third and forth sheet portions and these sheet portions are hingedly connected to each other.

Abstract: A rigid self-supporting highway delineator post having reflective material mounted at the upper end and a first flex area at a height above grade and a second flex area located immediately below the reflective material whereby the post is non-destructively bent down about the lower flex area when hit by a moving vehicle and may be bent about the upper flex area to facilitate removal and insertion of sheets of reflective material.

Abstract: A folding scaffold sign. The sign is constructed of a special honeycombed plastic material in which two sign panels are provided, separated by a fold line. The bottom corners of the panels are provided with metal legs inserted through openings forming the honeycomb structure. The legs are retained in the openings by elasticity and friction of the plastic memory material and the sign can be used as a triangular free-standing sign supported upon a floor surface, ground or the like. The sign may further be used as a cover for an existing conventional post-supported sign by placing the folded sign thereover and folding the panels together and retaining the legs in secured condition by a retaining chain. The folded-over sign may be stored in the same presentation when the panels are folded over against one another in superimposed position.

Abstract: An improved roadside reflector assembly which when mounted alongside a road is continuously visible by retroreflected light by the driver of a vehicle moving along the road at night-time within a viewing angle of from about 0.degree. to 60.degree. relative thereto, where 0.degree. extends substantially parallelly to a tangent to the road in the region where such reflector assembly is located. Also, such driver continuously sees retroreflected light at any given instant of time while approaching and passing a group of the reflector means so employed and so located, the individual such reflector means being longitudinally spaced from one another along such a road.

Abstract: A yieldable roadway signing and delineating apparatus is disclosed. A standard is positioned at a safe distance from the roadway to avoid snowplows, mowers and other errant vehicles. A horizontal moveable arm extends toward the roadway and carries a sign at its free end, thus placing the sign or delineator at the required position near the roadway for viewing by passing vehicle operators. Means for moveably retaining the arm in a desired position, permitting its deflection by pressure, and returning the arm to the desired position upon release of pressure are provided. Thus, the sign can yield to pressure from snowplow and mower attachments with a minimum or no damage to the sign. A delayed action mechanism is provided wherein a sealed fluid filled canister is eccentrically positioned around a shaft to which a gate is pivotally attached.

Abstract: A traffic controlling and road hazard warning device comprising a resilient frustro-conical or cylindrical road marker and a plurality of informational sign cards that are interchangeably and separably mounted on the upper end of the marker by means of slots and so designed to engage the upper end of the marker thereby securing the cards and preventing their rotation, yet allowing rapid installation and positioning of the cards on the marker.

Abstract: A directional sign for providing observers with directional information to a particular location or event and including a rectangular signboard with indicia provided on one face of the signboard describing the particular location or event. Three directional indicators are provided on the face of the signboard closely adjacent three of the four edges of the signboard and oriented respectively upwardly, to the left, and to the right relative to the indicia. Means is provided to facilitate removing from view two of the three directional indicators when installing the directional sign for use so that only one directional indicator remains visible on the face of the installed sign and this indicator serves for signifying to observers of the sign the one correct direction which should be followed to the particular location or event.

Abstract: A changeable directional sign for providing observers with directional information to a particular location or event and including a generally rectangular sign board having a height dimension greater than its width dimension and with printed indicia on the face of the sign board describing a particular location or event. An elongate indicator of a length no greater than the height dimension of the sign board is pivotally secured to the rear of the sign board at a predetermined location on the upper medial portion of the sign board. The indicator, when manually positioned either upwardly, to the left, or to the right, extends in projecting relation beyond either the upper or side edges of the sign board to thereby indicate to the observer of the sign that the direction which should be followed to the particular location or event is either straight ahead, to the left, or to the right.

Abstract: A modular display sign system comprising a display panel, struts integrally formed into the panel for support of the sign, a fastening system employing both an adhesive pad and fastening members for affixation of the sign to a desired point of use, and an interchangeable system of labels designed for affixation to the sign in order to convey a variety of messages.

Abstract: A sign serving as a deterrent to unauthorized parking is mounted on a post which is resiliently supported by a base in a normal vertical position and is adapted to be deflected into an inclined position by the car bumper when overriding the base in driving head-in into the parking space. The base has a vertical wall which guides the post in returning from the inclined to the normal vertical position preventing rearward deflection and has an open front shaped to permit the forward deflection of the post through a predetermined horizontal angle. An axial helical tension spring for a tubular post or a spring biased pivot for a channel shaped post connects the respective post to the base for the resilient deflectability.A wire slide-guard is mounted along the post spaced from the sign to engage the car bumper and any protruding portions of the undercarriage for smooth passage therealong to facilitate the deflection and prevent the sign from locking thereon when the car backs out of the parking space.

Abstract: A portable safety traffic barrier comprises a vertical hollow column of a thin flexible material upstanding from a base and a pair of vertically spaced substantially parallel hollow members of a resilient flexible material extending horizontally from the vertical column. Each of the column and horizontal members are inflated with a gaseous medium or are filled with a resilient medium so that the column and horizontal members will return to their initial positions after any impact thereto. The free ends of the arms are connected by a web and there is a light on one of the horizontal members connected through electrical leads to a battery mounted on the base. The leads are passed through loops on the column and horizontal member to secure the leads in position.

Abstract: A self-righting tippable roadway marking device includes a base member with a substantially spherical lower ground-engaging surface. A blind bore is formed in the base member centrally thereof and is adapted to releasably retain a staff element fixedly therein. An elongated staff element has its lower portion mounted non-rotatably in the blind bore and has a plurality of wind vane elements secured fixedly thereto. The wind vane elements extend radially outwardly from the staff element and are spaced equidistantly thereabout. Thus, in response to wind or other forces, the marking device will exhibit a tipping and rotating movement on its spherical lower surface.

Abstract: A sheet of clear plastic or vinyl type material having a clear adhesive covering the entire one side thereof so to adhere to a front of a roadway sign and prevent it from becoming defaced by vandals having spray cans of paint; the sheet being readily peeled off and replaced by a fresh sheet after being excessively defaced.
