Abstract: An emergency warning device comprising a base, three arms extending upwardly from the base to define an equilateral triangle, one of the arms extending horizontally on the base and the other two arms extending upwardly. Each arm has reflective and fluorescent portions on opposed surfaces thereof. The fluorescent portions of said arms comprising spaced walls and each wall has at least one opening therethrough. The opening in one wall is staggered with respect to the opening in the other wall such that portions of one wall overlie the opening in the other wall and such that air striking the device flows in a sinuous path through the device reducing the drag on the device.

Abstract: An emergency warning device comprising a base, three arms extending upwardly from the base to define an equilateral triangle, one of the arms extending horizontally on the base and the other two arms extending upwardly. Each arm has reflective and fluorescent means on opposed surfaces thereof. Vane devices are constructed and arranged, shaped and positioned on the equilateral triangle and such that air flow against a face of the triangle produces a downward force tending to prevent movement of the device relative to a road surface.

Abstract: A truck mirror comprising a unitary housing having a back wall, side walls and top and bottom walls defining a generally rectangular opening. The side walls have inwardly extending spaced flanges. The bottom wall terminates short of the side walls so that a flat mirror can be inserted by sliding longitudinally upwardly through the spaced flanges toward the top wall. A top end cover member is interposed between the top edge of the mirror and the top wall and has end portions extending laterally behind the outermost flanges along the side walls. A bottom end cover is interposed between the bottom edge of the mirror and the bottom wall of said housing and has portions thereof extending upwardly along the outer face of the lower edge of the mirror. The bottom end cover also has portions thereof extending inwardly in overlying relation to the bottom wall of the housing.

Abstract: A rotating lamp comprising a lamp base and an electric motor mounted on the lamp base. The electric motor drives a hollow shaft on which the lamps are mounted. A conductive rod extends through the shaft and is electrically isolated from the shaft. The lamps which are mounted on the shaft are electrically interconnected between the rod and the shaft. The housing of the electric motor is electrically isolated from the base. Brush means provide electrical continuity between the power source and the rod. Additional brush means provide electrical continuity between the shaft and the base.

Abstract: A combined lamp and turn signal for a snow plow or the like comprising a housing which supports a sealed beam headlight lamp bulb and a signal and parking lamp bulb. The housing has an elongated opening through one wall thereof and a grommet is positioned in the opening. The grommet has spaced flanges which engage the inner and outer surfaces of the portion of the housing defining the opening and extend continuously about the opening. An outer swivel plate having substantially the same configuration as the outermost flange engaging the outermost flange and an inside plate having substantially the same configuration as the inner flange of the grommet engages the inner flange. The flanges of the grommet and the inside and outside plates have aligned openings and fastening means extend through the openings.

Abstract: A vehicle lamp comprising a housing having a base wall and a peripheral wall surrounding the base wall and having a free edge and a first lens adapted to overlie the free edge of the peripheral wall. The peripheral wall has an opening therein extending toward the lens and a second lens is provided in the opening and has a free edge aligned with the free edge of the peripheral wall. An annular gasket is positioned on the peripheral wall and engages and holds the second lens in position. The first lens and the gasket have cooperating portions to provide a seal between the first lens and the gasket.

Abstract: An emergency warning lamp comprising a base, a mounting plate mounted on the base, and an electric motor mounted on the plate having an output shaft extending upwardly through the plate. A bushing is disposed centrally of the base on the plate, and a plastic gear is rotatably mounted on the bushing. A pinion meshes with the gear and is fixed to the shaft of the motor. A lamp bulb is mounted on the bushing. A heat shield overlies the gears and is supported by one of the gears for rotation. A reflector is mounted on the heat shield for rotation therewith. Electrical leads extend from a source of power, one of the leads comprising a ground lead and the others comprising power leads. One of the power leads extends through the bushing to the lamp. The other of the power leads extends to the winding of the motor. The housing of the motor is grounded to the metal plate and the ground lead is connected to the metal plate. The current flows through the bulb to the bushing and in turn to the mounting plate.

Abstract: A lamp comprising socket mounting assembly which includes a retainer engaging the interior of said hollow portion of said housing. The retainer has an opening therein and a shock absorbing mount member extends through the opening. The member is made of resilient material and has spaced annular flanges extending along opposite sides of the retainer. One of the flanges has circumferentially spaced integral protuberances extending axially and engaging one surface of the retainer for holding the opposite surface of the retainer against the opposite flange. The shock mounting member has an axially extending opening therein. A socket retainer has a planar surface engaging the end of the shock mounting member. The socket retainer has portions thereof crimped into engagement with the periphery of the shock mounting member. A socket member has an end with a reduced diameter extending through the opening in the socket retainer and the end is crimped outwardly.

Abstract: A truck mirror comprising a U-shaped support on which a mirror is pivotally mounted. The ends of arms of the support are pivoted to vertically spaced brackets that are adapted to be mounted on the truck. Pivot means are provided between the ends of the support arms and the brackets and comprise two members of low friction material fixed to the arms. The pivot members define a chamber in which an axially movable member is positioned. One of the pivot members has axially extending circumferentially spaced grooves therein and a movable member has complementary projections. The movable member is yieldingly urged toward the member having the grooves such that the mirror is held in angularly adjusted position but may be readily moved to a new angular position by manual manipulation.

Abstract: A back-up lens for a stop, tail and signal lamp comprising a body of clear plastic material having an inner surface with dioptrics and catadioptrics thereon and an outer surface with cylindrical surfaces thereon.

Abstract: A marker lamp comprising a housing and a lens. The housing has an opening into which the lens extends. An O-ring is positioned in a circumferentially extending groove in the opening of the housing. The lens has a cylindrical portion that extends into the opening which has a cylindrical surface that is engaged by the O-ring. The cylindrical surface has a length in a direction of the axis thereof greater than the width of the groove in the housing. The lens also has circumferentially spaced axially extending projections on a portion of the lens that extends axially beyond the groove.

Abstract: An assembly comprising a lens, a housing assembly including a bottom wall and a resilient mounting member fixed on the bottom wall. The resilient mounting member has a central portion spaced from said bottom wall and having a centrally located opening therein. A socket base is provided which has a centrally located projection that extends through the opening in the resilient mounting member. A grounding strap is fastened to the projection of the socket base and extends beneath the resilient mounting member.

Abstract: A warning lamp comprising a housing having an annular wall, a bulb having a filament within the confines of the annular wall and a lens closing the end of the annular wall. The lens has a front wall and a peripheral wall surrounding the front wall and telescoped over the annular wall of the housing. A prism is provided on the lens along at least opposed side portions of the peripheral wall of the lens and is constructed and arranged to redirect light from the filament of the bulb in a direction generally at 90.degree. to the axis of the lens.
