No. 13411.—15th February, 1901.—A. LESCHEN AND SONS ROPE COMPANY, of St. Louis, Missouri, United States of America, a corporation created by authority of the laws of the State of Missouri, and doing business at 920 and 922, North Main Street, St. Louis aforesaid. An aerial wire-rope tramway.

Extract from Specification.—This invention relates to improvements in aerial wire-rope tramways, and the objects of this invention are,—(1.) To provide an endless double-rope bucket tramway with loading- and dumping-terminals, one rope of which is a stationary bucket-supporting rope on which the bucket runs, and the other is a traction and bucket-moving rope which automatically picks up a standing bucket at a predetermined point at each terminal, and carries it to the opposite terminal, and leaves it at a predetermined point, and picks up the standing bucket, which is at a short distance from the one it leaves, when the one it has just left is moved to the standing position and is either loaded or dumped, as the buckets are at the loading- or dumping-terminal. (2.) To provide terminals for wire-rope tramways, having means for releasing the buckets from the traction-rope and for catching and holding to them and successively retarding their movement until they stop at a predetermined point. (3.) To provide positive-operating mechanism for stopping and holding a bucket at a predetermined point as it runs off the standing-rope on to the tracks of the terminals. (4.) To provide means for automatically grasping the rope clip of each bucket at the predetermined point at which they are stopped and held on entering the terminals, and for holding to the clip until it is automatically locked to the standing, loaded, or dumped bucket, as the case may be. (5.) To provide positively operating mechanism for grasping, holding, and moving said bucket, and for positively retarding the movement of the bucket coming on to the terminal tracks to be loaded or dumped, during its movement from its first stopping position to its first standing or loading and dumping position, and for positively and automatically accelerating the movement of the loaded or dumped bucket from its standing position until it attains the speed of the traction-rope, and is locked to the rope-clip that leaves the incoming bucket, thereby insuring the positive releasing of the rope-clips from the buckets as they enter each terminal; positive stopping of each bucket at a predetermined point until the clip just released from it registers in the lock of the bucket at the loading- or dumping-station; positive movement of both buckets at each terminal, the one at the loading- or dumping-station on its way out, and the one just in to the standing-point to be loaded or dumped; positive accelerating movement of the loaded or dumped bucket from the standing-, loading-, or dumping-point, and positive holding to it and movement of it until it is locked to the rope-clip, and positive holding and moving of the bucket just in, independent of the traction rope, from its first stopping position, and a positive retarding movement of this bucket to the standing, loading, or dumping position, in order that the standing bucket may be out of its way, and that both may move in relative unison while the rope-clips are unlocked from and are leaving one and engage with and are locked to the other while the traction rope is moving continuously, and the buckets are loaded and dumped. (6.) To provide means for dumping the buckets automatically.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the descriptive part of the specification is inserted instead.]

Claims.—(1.) The process for the manufacture and repair of incandescent electric lamps consisting of the reinforcement when new or the regeneration when old of the filament within the bulb, by the deposition on the said filament of a coating of carbon whilst the said filament is sealed and fixed in the glass bulb in which it is eventually to be or has been formerly used, substantially as set forth. (2.)

(3.) In a process for the regeneration or “flashing” of filaments in situ in their working-bulbs, the regulation, by means of pressure-controlling valves or cocks upon the entry and exit respectively of the pressure of the gaseous mixture used in the “flashing” of incandescent filaments according to the voltage or candle-power of the same, and in accordance with the size of bulb, substantially as described. (4.) In a process for the “flashing” or regeneration of filaments in situ in their working-bulbs, the simultaneous use of a photometer during such reinforcing of the filament to indicate the point at which the regeneration is completed, substantially as and for the purpose set forth.
