Abstract: A paver screed has a main screed with two outer side walls, at least one of the side walls being provided with insertion orifices for the releasable mounting of at least one lateral screed extension by means of fastening elements capable of being inserted through the insertion orifices. A screed extension has fastening elements that comprise hydraulic cylinders which each have a piston that is spring-biased into an initial, retracted position. The cylinders are actuated by hydraulic fluid to displace or extend the piston against the biasing action of the spring. Preferably, the hydraulic cylinders are connected a hydraulic circuit of the main screed. The piston of each hydraulic cylinder carries a shank capable of being inserted through a proximal insertion orifice and which are preferably provided with an abutment element configured for attaching the cylinder to the sidewall of the main screed.

Abstract: A motorized golf car includes a sing-sheet thermoplastic sunroof having a plurality of hollow stiffener channels formed therein to stiffen the canopy. A first, hollow stiffener channel is formed at the perimeter of the canopy edges, along the front and side perimeters. A plurality of second stiffener channels are formed in the sheet in-board of the first stiffener channel. A first drain gutter, sloped back-to-front, is provided in the canopy, and a second drain gutter, sloped front-to-back, is provided in the canopy to drain water from the top surface of the canopy.

Abstract: 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.

Abstract: A check valve system is for a fluid-actuated percussive drill assembly including a casing, a backhead connected with and extending into the casing, and a fluid distributor disposed within the casing. The backhead has a central axis, a supply passage extending along the axis, and an outer surface section extending circumferentially about the axis and disposed within the casing. The check valve system includes a port extending between the outer circumferential surface section of the backhead and the supply passage. Preferably, several ports are spaced circumferentially about the backhead outer surface. An annular check valve is disposed about the outer circumferential surface section of the backhead and is configured to alternately permit fluid flow through the backhead port and substantially seal the backhead port.

Abstract: An expandable cup holder for a golf cart includes a support member forming a substantially planar top surface for the cup holder. The support member is fastened to a vehicle with the support member top surface oriented substantially horizontal. The top surface forms a top aperture large enough to receive a plurality of cup sizes. A plurality of flexible fingers are spaced apart from each other around the perimeter of the aperture. The fingers extend conically downwardly toward each other below the top surface, to form a slotted, frustum-shaped member that flexibly contacts and frictionally retains a plurality of cup sizes therein. Front and side walls on the support member surround and support the frustum-shaped member. The front wall includes apertures for retaining golf tees.

Abstract: 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.

Abstract: 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.
