Abstract: Device for placing label sleeves (2) onto containers (1) such as bottles or similar items by means of a first apertured pusher (4), positioned coaxially with respect to a container which carries a partially positioned label sleeve, and which can be moved forward and backward axially with respect to the longitudinal axis of the container, in a controlled manner, and whose internal diameter is at least slightly smaller than the diameter of the label sleeve (2) and, coaxially with respect to the first apertured pusher (4), a second pusher (5) is provided internally, which is led in a manner so it can be moved axially with respect to the first apertured pusher (4).

Abstract: The invention relates to a device for placing label sleeves (2) onto containers (1) such as bottles or similar items by means of an apertured pusher (4), which is positioned coaxially with respect to a container which carries a partially positioned label sleeve, and which can be moved forward and backward axially with respect to the longitudinal axis of the container, in a controlled manner, and whose internal diameter is at least slightly smaller than the diameter of the label sleeve (2), where, coaxially with respect to the apertured pusher (4), a second pusher (5) is provided internally, which is led in a manner so it can be moved axially with respect to the first apertured pusher (4).

Abstract: The contact pole of a trolley bus carries at its normally upper end a trolley shoe and an upwardly projecting guide which may jointly pivot on the pole about an approximately vertical axis. When the pole is partly raised by a heavy spring and swung horizontally, the trolley shoe is vertically aligned with an overhead wire when the guide abuts against the wire. When the pole is further raised by the spring, the trolley shoe engages the wire, and the guide is automatically dropped below the trolley shoe so as not to collide with hangers for the overhead wire. When the pole is lowered by an operating mechanism against the biasing force of the spring, a motor-driven element of the mechanism connected to the guide by a motion transmitting train automatically returns the guide to its position above the trolley shoe.
