WINDING DRUMS AND DUMP CARS.
As steam has taken the heavy work of transporting the pro ducts of the country from the horses which formerly did the overland hauling, so it is doing now in the brick and tile fac tories.
The apparatus for drawing the clay into the factory by the engine, being in the first place cheaper than horses and carts and doing the work without a driver, besides not being at ex pense when idle, it was a natural result that the winding drum and automatic dump cars were adopted by all enterprising brick manufacturers.
To suit different demands, the Frey-Sheckler Co., of Bucyrus, Ohio, has constructed two styles of winding drums, which are self-contained in substantial iron frames, and can be operated by a cord from the clay pit or by the engineer from any point in the factory.
Fig. i6 illustrates the Friction Winding Drum which the Frey-Sheckler Co. make in three sizes, to wit: Nos. 1, 2 and 5. A machine of this kind is one of the essentials of a well equipped brick factory, for the transportation of clay from the pit to the factory. This Drum is substantially built. The frame is heavy, and is so constructed that it can be bolted to the upper part of the track timber.
No. i Drum has a friction pulley 4o inches diameter and 7 inch face. The paper friction pulley is 8 inches diameter and 7 inch face. The driving pulley is 24 inches diameter and 6 inch face. Speed, 500 revolutions per minute ; geared 5 to I ; weight of Drum without cable, ',too pounds. Drum will hold 800 feet -inch iron cable.
No. 2 Drum has a friction pulley 3o inches diameter and 6 inch face. The paper friction pulley is 6 inches diameter and 6 inch face. The driving pulley is 26 inches in diameter and 6 inch face. Speed, 500 revolutions per minute ; geared 5 to 1; weight of Drum without cable, 700 pounds. Drum will hold 300 feet Winch iron cable.
No. 5 Drum is 24 inches diameter and 36 inches long inside of flanges, which are 5 inches high all around. Diameter of main shaft, 3 inches ; diameter of pulley shaft, 23A inches. Speed, 35o revolutions per minute ; geared 5 to 1. Driving pulley is 24 inches diameter, to inch face. This drum will hold 3,400 feet of cable. Weight of drum without cable, 4,500 pounds. Floor space required, 7 feet by 5 feet 9 inches.
Fig. 17 illustrates the gear and friction winding drum made by the Frey-Sheckler Co., which is made in two sizes, to-wit: Nos. 3 and 4. The construction throughout is strong, simple and durable. It is not liable to breakage or derangement, and is mounted on a solid white oak frame. The drum runs loose on the shaft and engages itself with the wood friction (which is securely bolted to the large spur gear) by being forced along the shaft by means of the lever.
This lever is connected by a rod with the band brake lever, so that both the friction and the brake levers are operated by one movement. Thus with the levers in a central position, as shown in the engraving, the drum is left free to revolve on the shaft. When the levers are forced down the brake is applied,
and holds the drum or lowers the load as desired. When the levers are raised the drum is brought into contact with the friction disc and raises the load, then the brake is released. This brings it fully under the control of the operator.
No. 3 Drum is 12 inches in diameter and 24 inches long in side of the flanges, which are 5 inches high all around. The driving pulley is 24 inches diameter, 8 inch face. Speed, 550 revolutions per minute ; geared to 1. This drum will hold 1,300 feet of inch cable. Weight of drum without cable, 1,725 pounds.
No. 4 Drum is 24 inches in diameter and 3o inches long in side of flanges, which are 5 inches high all around. Geared 5 to 1. Diameter of main shaft inches, diameter of pulley shaft 2 3 inches. Speed, 350 revolutions per minute. Driving pulley is 24 inches diameter, 8 inch face. This drum will hold 2,80o feet inch cable. Weight of drum without cable, 3,500 pounds. Floor space required, 6 feet 7 inches by 5 feet 8 inches.
The speed of the above drums was based upon the supposi tion that the dump car travels six miles per hour.
Fig. i8 illustrates the Side Dumping Clay Car, made by the Frey-Sheckler Co. This car is substantially constructed in all parts ; it is made to dump on one side only, but it can be furnished to dump on both sides if desired. The side is hinged from the top and arranged so that when the car is tilted over the catch holding the car in position is released, allowing the side to swing out at the bottom. The wheels, 17 inches in are very heavy, chilled and annealed. This car is made in three sizes. No. 3, capacity 3% cubic yard, track gauge, 36 inches ; No. 4, i cubic yard, track gauge, 36 inches ; No. 5, i cubic yards, track gauge, 42 inches.
Fig. 19 illustrates the Bottom Dumping Clay Car, manu factured by the Frey-Sheckler Co. This car is remarkably strong. The timbers are heavy and securely bolted together ; the wheels, 17 inches in diameter, are thoroughly chilled and annealed, and the workmanship throughout equal to the high est established standard. This car is arranged to dump auto matically. The bottom is in two parts and hinged at the sides of the box, and held in position by two chains which are attached to an arm keyed to a steel cross-shaft which has a lever on the outside of the car, which is held in position by a catch that hangs down between the wheels near the track. A stop fastened to the track releases this catch and lets the bottom drop, when the car runs back, and the diggers, by a pull of the lever, again place the bottom in position. The Frey-Sheckler Company make two sizes of this style of car. No. 1, capacity 34 cubic yard, track gauge, 42 inches ; No. 2, capacity t cubic yard, track gauge, 42 inches. •
