Abstract: A turnstile construction wherein arms normally block the path of movement of persons passing through the turnstile. The arms are engaged when authorized passage is available, and this results in movement of the arms either by the force of the person passing through or in a motor-assisted fashion. The head supporting the arms includes a control system including a drive gear tied to the arms for rotation during movement of the arms. Rotatable locking members are connected to the drive gear, and engaging arms are movable into and out of engagement with the locking members for purposes of controlling use of the turnstile. The engaging arms are normally controlled by the deposit of a proper fare whereby in the course of normal use, only persons paying a fare can pass through the turnstile. When locked, the system automatically protects against breakaway even when an extreme load is applied.

Abstract: This invention relates to means for imparting angular movement to a first member connected to a second member by a hinge in one sense about said hinge pivot axis.

Abstract: A gate or panel including a frame composed of channel members each of which has opposed side walls bent inwardly to define a slot for receiving edges of the chain link fabric which is within the frame. An end link of the fabric, which is in the slot in the adjacent side member, is turned to prevent withdrawal thus securing the fabric to the frame. Each of the frame members has a partition wall extending between the opposed walls so as to stiffen the gate frame. Depending upon the space between the slot and the partition wall it may be necessary to slide the end links into the channel from either end in order to turn the end links rather than inserting the links through the slot from the sides.

Abstract: A sliding wing door, as used in railway and similar installations, is disclosed, of the kind in which the door, as it is opened, is first thrust out of its doorspace and slid alongside the vehicle body, the improvement consisting in that one of the component parts of the telescopable guide of the door panel is secured to the movable members of at least two linear ejectors intended to thrust the door panel out of the doorspace. Advantageously, the axes of the two (or more) linear ejectors are inclined through an angle of from 45.degree. to 90.degree. relative to the door space plane. A vertical shaft, mounted parallel and adjacent to the door post provides the initial movement of the door in a direction parallel to the ejector axes: the angle of rotation of the shaft is appropriately limited consistently with the necessity. Certain translation movements of component parts of the mechanism are aided by sets of rollers sliding on specially provided rolling paths.
