Wheels C include a contoured surface 54 for forward movement and a rounded contoured surface 56 for transverse movement. Surface 56 provides a rounded support surface over which the load may be broken and transported in which configuration the load is supported in a raised position for transporting long loads transversely down narrow passageways without dragging and sagging ends of a long load.

Abstract: A method and apparatus for opening and mixing the fibers from a plurality of bales according to a predetermined mixture. The device includes tongs-like gripper means which press into the fiber bales for removing fibers therefrom. A measuring means and a control means determine the width of opening of the gripper means. A control circuit is provided for receiving a signal representing the weight of the first pick-up from a particular bale and the weight of the fibers deposited in a receiver container. When the sum of these signals is equal to the preset desired weight of the fibers that are to be deposited in the receiver container, a compared signal is produced causing the tongs on successive pick-ups to be opened to a lesser degree. As a result, a high degree of accuracy is obtained when mixing to a predetermined ratio while maintaining a high production output.

Abstract: Heater apparatus is disclosed having a metal firebox in which fuel is burned and an outer ceramic enclosure having ceramic mass walls which absorb excess heat when the heater produces more heat than is required and distributes the heat gradually by radiation after the heater output becomes less than the heat stored in the ceramic mass. The ceramic mass walls are spaced from the metal firebox walls to provide air passages through which air may be circulated by means of a blower so that rapid heating may be had of the interior space when the firebox is initially fired by transferring the heat radiated from the metal walls directly into the room by forced convection. After the interior space is heated to a desired temperature, the blower may be cut off and the room may be heated more slowly at a more even temperature by radiation from the ceramic mass.
