Abstract: A hinge pin and bushing assembly is provided for machine insertion into a barrel of a hinge leaf. The assembly is preferably molded in one piece from a resilient self-lubricating plastic and includes a bushing having a concentric bore, a hinge pin having an end connected to the bushing concentrically with the bore by thin webs. The other end of the hinge pin is attached concentrically to a cylindrical plug. The bushing portions of a pair of assemblies are inserted into opposite ends of the leaf barrel and compressive force is applied to the outer ends of the plugs thereby breaking the webs and inserting the hinge pins into the bushing bores.

Abstract: A window frame has one or more latches provided internally of a vent sill for pivotal engagement with a latch strike in the interior of a frame sill and a latch actuator extending outwardly through an opening in the inside face of the vent sill. A spring urges the latch into engagement with the strike with the latch and the actuator being movable in a linear horizontal direction so that a slot in the side of the actuator engages the edges of the opening through which the actuator extends to hold the actuator and the associated latch in a locked or non-pivotable condition. A second embodiment employs a similar pivotal and slidable latch member in a side frame of a horizontally movable vent frame which is pivoted into latching position inside an opening in a fixed vertical meeting rail and is retained in locked or non-pivotable condition by subsequent linear vertical movement of the latch to a restricted slot portion from which it cannot pivot from the locking position.
