Abstract: Disclosed herein is a valve assembly. The valve assembly includes a valve body, a cartridge, a hot side check stop, and a cold side check stop. The valve body has a cartridge receiving area, a first check stop receiving area, and a second check stop receiving area. The cartridge is located in the cartridge receiving area. The hot side check stop is located in the first check stop receiving area when the valve assembly is in a first configuration. The cold side check stop is located in the second check stop receiving area when the valve assembly is in the first configuration. When the valve assembly is in a second configuration, the hot side check stop is located in the second check stop receiving area and the cold side check stop is located in the first check stop receiving area.

Abstract: The present invention relates to a leaf stripper for removing leaves from a plant. The leaf stripper includes a housing having an interior. The stripper has a grille supported by the housing and in communication with the interior. The grille is shaped to selectively enable the leaves to at least partially pass therethrough. The stripper has a stripping motor disposed within the interior of the housing and supported by the housing. The stripper has a rotatable string member operatively connected to the stripping motor. The string member is configured to create a partial vacuum within the interior of the housing for at least partially sucking the leaves through the grille when rotated and to at least partially shred the leaves at least partially passing through the grille.

Abstract: A portable workbench includes a top structure, a support structure and a collapsible frame. The top structure includes upper work supporting surfaces lying in a common plane and longitudinally extending opposed side portions defining clamping surfaces. A linkage mechanism cooperates with the frame to actuate the workbench between an expanded working position and a collapsed transport position. A lever releasably cooperates with the frame to maintain the workbench in a locked expanded position.

Abstract: A portable workbench includes a top structure, a support structure and a collapsible frame. The top structure includes top members lying in a common plane. The top members include upper working surfaces and lower supporting surfaces. The lower supporting surfaces include a plurality of rib portions formed thereon. The top members further include longitudinally extending opposed side portions defining clamping surfaces. A linkage mechanism cooperates with the frame to actuate the workbench between an expanded working position and a collapsed transport position. A lever releasably cooperates with the frame to maintain the workbench in a locked expanded position.

Abstract: A work bench includes a frame, a bench surface on the frame with the bench surface including at least two members, one of which is movable along the frame for clamping a workpiece between the members. A mechanism for moving the member includes two screws coupled with the members. The two screws are spaced with the member for moving the member upon rotation of the screws. A sprocket is coupled with each of the screws. A transmission belt or chain is coupled with the sprockets. At least one handle is coupled with one of the screws to rotate the screws. At least one clutch is coupled with the at least one screw to limit clamping pressure on the workpiece. The clutch enables rotation of one screw with respect to the other screw so that workpieces may be clamped between the members and clamping of the workpiece may be accomplished by rotation of the screws with one hand of the operator. Also, a guard may be present which covers the transmission belt or chain.
