Abstract: 22,026. Bayes, R. J. Hart-. Oct. 6. No Patent granted (Sealing fee not paid). Shaking supports for supplying solid; solid, supplying from pocketed drums. - In an automatic device for supplying carbide &c. to acetylene and other gas generators, the solid rests on a series of inclined trays arranged zig-zag fashion, one or more of the trays being arranged to be shaken when the gas-holder bell reaches certain positions, thereby delivering appropriate quantities of material to the generator. In the plant shown in Fig. 1, two trays are employed, the upper one b normally resting on a support e, while the lower one c rests on springs h on pins i, and on a support j. The lower end of the second tray is in the path of the divisions 16 of a pocketed drum 15, so that as this drum is rotated, the tray c is first raised and then released, discharging a portion of its charge into the succeeding pocket. This movement may also be communicated to the upper tray by legs 17 connecting the two trays. The drum is driven in one direction through ratchet and spur gearing by a weighted lever 11, one end of which projects into the path of a stop 2 carried by the gas-holder bell. Rotation of the drum delivers a charge of solid on to the door m of the receiving box, and this door is released, when the projection 2 in its downward movement rocks the part y, to which the door is connected through the lever w, and arm u. The bell rises after the charge has entered the generator, and again rocks the part y, lifting the door and closing the lower parts of the receiving box. In the modification shown in Fig. 4, the pocketed drum is dispensed with, and the upper part of the receiving box is closed by a door 26, and the lower tray co-acts with a gate 27 resting on a lever 30. The stop on the bell on its upward movement actuates a lever 11<x>, and raises the lever 30 through a plunger 33. The tail of this leverreleases the door, and at the same time the gate 27 and the lower tray are raised, and are maintained in this position by a stop 35 on the lever 11<x> engaging a ratchet 36. The charge on the upper door is discharged on to the lower one, which is released on the downward movement of the bell by the stop 2 engaging a lever 37, and releasing the door-retaining catch 39 through a, rod 38. The tail of the door actuates a lever 43, which is moved into the path of the stop 2, so that the latter in its upward movement raises the door until it is again held by the catch 39. The outward movement of the lever 43 also releases the ratchet 36 from the catch 35, and allows the lever 11<x> to fall so closing the upper door, and delivering a fresh charge on to it from the lower tray. In a further modification, the plunger 33, Fig. 6, is actuated through a ratchet 44 so that it is released after a certain upward movement of the bell, and the door closed, and a-fresh charge delivered on to it. In the down. ward movement of the lever 11<x>, the pawl is telescoped until it springs back under the end of the plunger 33. The trays are made of non- corrodible material such as glass, and the flanges at the lower end of the tray c may be sprung inwards to adjust the frictional resistance.
