Abstract: A thumb operated door latch and lock assembly has an exterior grip and thumb lever, a motion converter, a key cylinder, a strengthening plate and an interior latch lever and locking knob. The thumb lever moves the converter which turns a latch tongue that extends through a receiver in the latch assembly. The interior lever turns a limited engagement interior hub collar. A figure eight opening in the collar turns the latch tongue to withdraw the latches. Turning the interior lever upward disables the thumb lever. Turning the lever to withdraw the latches moves a slide upward within guide plates. The slide turns an interior lever and an extended tongue on the key cylinder to withdraw the dead bolt simultaneously with the latches.

Abstract: A three-way adjustable butt hinge for a door is adjusted vertically in a door frame by inserting an allen wrench in a vertical adjustment screw at the top of the hinge pin. Turning the wrench moves the screw in either direction, pushes on the hinge pin and raises or lowers the door as necessary. A pin has an eccentric shaft with upper and lower sections offset on parallel axes. Lateral adjustments are effected by loosening a side-mounted set screw and turning the eccentric shaft as necessary to move the door either in or out or side to side in the frame. The lateral set screw holds the hinge pin integral with the sash hinge. The door is removed from the frame by simply lifting the door sash hinge and pin from the complementary pin receiver on the frame hinge.

Abstract: A plastic casement windows operator has a plastic housing, a plastic sliding tounge and a plastic operating lever. The housing has a plastic main body and a plastic cover with complementary peripheral steps and peripheral energy directors and inward extending receivers and pins with energy directors for joining the cover and main body after the plastic sliding tounge and plastic operating lever are installed. The main body has an inward extending cylindrical bearing opening, which holds a cylindrical bearing integrally formed between an operating handle and an activator arm. An activator cylinder at a remote end of the arm moves in an oval groove in the sliding tounge. Wings on the tounge support opposite jugs and cylindrical guides which slide along inner guides on the cover and main body. An extension on the flat body tounge has a U-shaped opening for connecting a window linkage. Integral rims extend around the tounge, the U-shaped opening and the oval groove.

Abstract: A window operator, particularly, operators for venting casement windows is provided. The base housing of the operator is of a plastic polymer, which is a non-corrosive and non-thermal conducting material. The top and bottom base components are then sonic welded with a heat-treated steel worm gear welded inside of the plastic base of the window operator creating a one-piece assembly. The worm gear and pinion gear with attached operator arm are placed within the base body before fusion welding the top body. The use of the plastic polymer for the base housing eliminates the possibility of corrosion of the base material. Also, the polymer does not require finishing or painting to protect it from corrosion.
