The invention relates to a safety container for inflammable liquids, including a single valve body that has a pour-spout and a fill-spout, as well as a concerted venting means which are all located within the single valve body, thus eliminating user confusion and increasing safety by having one valve body containing all of these said functions.

A strike-off device is for a paving screed having a main screed and a screed extension attached to the main screed, the screed extension having a generally vertical front surface. The strike-off device includes a plate disposed frontwardly of and adjacent to the screed extension. The plate has a generally horizontal working edge extending laterally along the front vertical surface of the screed extension. Two connective members extend between the strike-off plate and the screed extension and are configured to adjustably attach the plate to the screed extension, such that vertical displacement of the connective members adjusts a vertical position of the strike-off working edge. Preferably, the connective members are each a threaded rod having a first end engaged with the strike-off plate and a second end engaged with the screed extension, such that rotation of the rods displace the strike-off plate in vertical directions.

Strike-off device for a paving screed

A retainer device is used with a screed assembly including a main screed and a pair of front-mounted screed extensions connected with the main screed. Each extension is pivotally attached to the main screed and has a front surface facing generally away from the main screed. The retainer device includes a retainer plate disposed adjacent to the front surface of the screed extension. A horizontally-extending rod has a first end connected with the retainer plate and a second end connected with the main screed. The rod is configured to displace the retainer plate between a first, most distal position with respect to the main screed and a second, most proximal position with respect to the main screed. At the most proximal position, the retainer member acts upon the screed extension such that the screed extension is retained generally in contact with the main screed. Further, the plate prevents rotation of the screed extension in a direction generally away from the main screed.

A screed assembly for use in paving material upon a generally horizontal surface includes a main screed having a generally vertical front surface. At least one and preferably two screed extensions are connected with the main screed. At least one and preferably a pair horizontally-extending support members each have a first end movably connected with the main screed and a second end connected with a screed extension. The support members are movable with respect to the main screed so as to displace the screed extensions alternately toward and away from the main screed front surface so as to adjust the angle of attack of the screed extensions independently of the angle of attack of the main screed. Preferably, an adjustment assembly or device is connected with the support member and is configured to displace the support member with respect to the main screed. The adjustment device includes a base attached to either the main screed or the support member, preferably the support member. A horizontally-extending rod has a first end attached to the other of the main screed or the support member and a second end movably engaged with the base. Movement of the rod with respect to the base displaces the screed extension alternatively toward and away from the front surface of the main screed so as to adjust the angle of attack of the screed extension.

A material flow modifying device is for a screed assembly of a paving machine. The screed assembly has a main screed with a central axis extending in a direction of intended travel of the paving machine and two screed extensions movably mounted to the main screed. The flow modifying device includes a deflector member connected with the screed extension and having a flow surface facing toward the central axis of the main screed. The flow surface is contactable with paving material on a base surface and is configured to displace the material toward the central axis when the paving machine moves in the intended travel direction. The deflector member has a first end disposed adjacent to the inner vertical surface of the screed extension and a second, free end disposed proximal to the front vertical surface of the main screed, such that the second end moves laterally along the main screed during movement of the screed extension. The distance between the member second end and the central axis is greater than the distance between the member first end and the central axis, such that the flow surface is angled inwardly and rearwardly toward the main screed central axis. Preferably, the deflector member includes a main body portion attached to the screed extension and a wear plate removably attached to the main body portion. Alternatively, the deflector member is formed as a main body portion only or even as an integral portion of the screed extension.

A wear compensating device for a slope adjusting assembly for an extendable screed section of a paver includes a saddle support assembly on the screed, for supporting an extendable screed section, a saddle assembly on the saddle support assembly for carrying extendable guide members to support the extendable screed section, and an adjustable cam follower positioned between the saddle assembly and the saddle support assembly for providing rolling contact between the saddle assembly and the saddle support assembly, to maintain alignment between the saddle support assembly and the saddle assembly.
