Abstract: A rear view mirror for vehicles such as automobiles and trucks, which provides a periscope-like rear view utilizing only two mirror surfaces. One of the mirrors is a substantially planar mirror, and the second of the mirrors is a curved part elliptical mirror. At least one of the mirrors is mounted outside the windshield, and the use of the part elliptical mirror surface provides the proper orientation of the image that is seen by a driver without utilizing prisms, lenses, or three mirror systems. The device is thus much more compact, more attractive in use, and still affords a substantially undistorted wide angle view to the rear.

Abstract: A door lock device suitable for operation with electrically operated means, which in turn can be actuated by magnetic card, special turn key, or a key punch combination for security purposes. If desired the lock device may be operated with a suitable mechanical or key lock mechanism. The door lock comprises a pivoting latch dog or bolt which is triggered to a locked position upon closing of a door. The pivoting dog or bolt is controlled by a toggle linkage which can be positioned near, on, or over-center to hold the door positively locked against external pressure. Means are provided for releasing the toggle linkage, even under loads against the door, by force directly applied to the toggle linkage between the end pivots of the linkage, and in addition springs are provided for moving the latch dog to an open position positively once the toggle linkage has been released. As the linkage is released the latch bolt moves the door to an ajar position.
