Abstract: 11,145. Bronder, G. A. May 30. Gas retorts.-Relates to improvements in the charging apparatus described in Specification No. 3577, A.D. 1895. Fig. 1 a vertical section of three retorts arranged one above the other, and an elevation of the double carriage with its scoops and scraper frames in operative and inoperative positions. Fig. 4 shows a section on the line B B, the hopper being removed, and Fig. 10 a vertical section through the hopper, scoops, and scraper frames. The main carriage C, C' runs by means of wheels D and rails B in front of the retorts A, A', A<2>. It carries track a upon which the wheels e of the scoop carriage E, E<1> run. The main frame carries a steam receiver C<4> from which two engines are driven, one, E*, for driving the scoop carriage by means of a chain &c. Q<3> driven by a drum on a shaft Q<2>. The chain passes around pulleys r, and is connected to the carriage by spring connections. The other engine C<o> moves the main carriage in front of the retorts by an endless screw on the shaft gearing with a worm-wheel on an axle d. The hopper H is carried by supports H<1>, H', H<3> at one side of the scoop carriage tracks a. It is divided into three compartments h, h<1>, h<2>, of approximately equal volume, forming shoots for the coal. The delivery ends of the shoots are curved, and beneath the curved ends are projecting plates n, extending from the plates r, and bent down at their outer ends to form the shoots N'. Beneath each curved plate is a pusher which carries the coal from the retaining-trough N to the shoot N<1>, from which it passes to the scoops. The scoops F, F<1>, F<2> are carried on brackets b, b<1>, b<2> under which are the journals of the rollers f, f<1> upon which the scoops are placed. Each scoop oscillates on its rollers f as a scale beam, a weight I being fixed at one end, and the charge of coal being received at the other. Each scoop may be fixed either to the main carriage, as shown by the upper scoop in Fig. 1, or to the scoop carriage, as shown by the two lower ones. Each scoop is formed as a long box or trough, and lying loose upon the upper edges thereof is a scooper frame J, consisting of angle-iron side bars and cross-braces J<1>, to which are pivoted series of scrapers J<2>. The rearmost scraper J<3> is rigid. The scraper frame is capable of a movement back and forth relatively to the scoop, that is, after the scoop with the scraper frame in it has been moved forward into the retort as at F<2>, the scraper has a further movement to push the charge to the extreme rear end of the retort, and, while the scrapers remain thus pushed forward, the scoop is withdrawn as shown at F<1>. This additional movement is brought about by a lever K pivoted to the weight I of the scoop, and having one end bearing against the counterbalance weight j<1> on the scraper frame. As the scoop is carried forward, the other end of the lever contacts with a roller stop K<11>, with the required result. The scraper frame is withdrawn again by a backing bar L, two pulleys, and a wire rope. This bar is brought against a stop g<1> as the scoop is returned, and is forced into the scoop, operating the wire rope to withdraw the scraper. To prevent shocks when the movements of the scoop carriage are stopped and reversed, buffer springs are connected to the chains running from the drum driven by the scoop engine. The scoops are locked to either main or scoop carriage by a bolt connected to a crank, at the end of wnich is a handle, which, by its weight, when swung over to one side or the other, causes the bolt to engage with the desired carriage. To spread the coal towards the sides of the retorts, a plough 32 is attached to the end cross-brace J<1>, and a plough 40, generally of triangular shape, is attached to the scoop. To cause the scoops to run in their correct positions, adjustable friction rollers 50 are employed.
