A connector for connecting a frame member to one or more other frame members of a space frame assembly is disclosed. The connector includes a body defining a surface and a projection extending outwardly from the surface along a main axis to define an axial end surface away from the surface. The axial end surface defines a curvature having continuity across an expanse of the axial end surface to facilitate formation of a full penetration weld joint between an end of the frame member and the axial end surface upon a contact of the end of the frame member with the axial end surface.

A system for improving alignment in welded assemblies is provided. The system includes a support member having a surface and a projection extending from the surface. The projection may include one of a convex or a concave geometry. The system includes a positioning member provided over the support member for receiving a frame member. The positioning member may be movable over the support member, and the positioning member may include a geometry configured to engage the one of the convex or the concave geometry. The frame member may be movable from a first position relative to a center of the projection to a second position relative to the center of the projection during movement of the positioning member over the support member.

A replaceable bearing insert may include a bearing surface including a curvature configured to be complementarily contoured to a trunnion ball. The bearing surface may be configured to be in confronting engagement with the trunnion ball. An outer surface opposite the bearing surface may be configured to be received in confronting engagement with an inner surface of an adapter. A first semi-annular flange may extend radially outwardly beyond the outer surface. A second semi-annular flange may extend radially outwardly beyond the outer surface. The first semi-annular flange and the second semi-annular flange may be configured to extend along a first side and a second side of the adapter, respectively, such that the inner surface of the adapter is positioned between the first semi-annular flange and the second semi-annular flange.

A pin joint for coupling a first component with a second component is provided. The pin joint includes a shell disposed within an opening in the first component. The shell has a bore and a coupling portion. The pin joint also includes a sleeve disposed concentrically within the bore of the shell. The pin joint further includes a retainer disposed proximal to an end of the sleeve and detachably coupled to the coupling portion of the shell. The retainer is configured to axially retain the sleeve within the bore of the shell. The pint joint includes a pin received through the sleeve and the retainer. The pin is engaged with the second component.

A bidirectional, spring-biased gate assembly includes a pair of side frames, an elongated hinge extending therebetween, and a gate extending vertically from the hinge. In a resting position, the gate extends vertically across an open interior between the pair of side frames, providing a movable barrier suitable for deterring and/or blocking animals from passing therethrough. The gate is able to transition between the resting position, a first lowered position perpendicular to the resting position, and a second lowered position perpendicular to the resting position in the opposite direction of the first lowered position. The gate assembly further comprises a plurality of springs extending between one of the side frames and the gate and are adapted to return the gate to the resting position from either the first lowered position or the second lowered position.

A pin for use in a dynamic pin joint is provided that comprises a core member that defines a longitudinal axis and an outer diameter and a self-lubricating material overlay that is disposed about the outer diameter of the core member along at least a portion of the longitudinal axis of the core member.

A sleeve bearing comprising a tubular body having an inner surface annularly about a longitudinal axis and an outer surface radially outward from the inner surface. The sleeve bearing includes a first side surface between the inner surface and the outer surface, and a second side surface between the inner surface and the outer surface. The sleeve bearing includes a first inner edge between the first side surface and the inner surface, and a second inner edge between the second side surface and the inner surface. The sleeve bearing includes lubricant reservoirs in the inner surface elongated along an elongation axis. An angle between the elongation axis and the inner edge is between 0 and 90 degrees. The lubricant reservoirs are in an interrupted pattern annularly around the inner surface so a portion of the inner surface between the first inner edge and the second inner edge is uninterrupted.

An extendable screed has independent height and angle of attack adjustment for a lower extender frame. At least one post and cylinder assembly are used to couple the lower extender frame to an upper extender frame at a pin that allows rotation of the lower extender frame relative to the upper extender frame. A vertical adjuster uses a drive rod with a pivoting attachment at the lower extender frame. An axis of rotation of the pin and an axis of rotation of the pivoting attachment are co-linear. This arrangement allows lower extender frame to move vertically while allowing angle of attack adjustments to be made about the co-linear axes of rotation. Simple screw adjusters displaced from the axis of the pin and collet assemblies allow raising and lowering the back of the lower extender frame to adjust the angle of attack.
