[Class 23.] A cleaning and separating plant for coal and other materials has a rotating concave disc with a smooth peripheral portion; the material is delivered in an attenuated stream at or near the centre, and means are provided for guiding the separated materials off the disc. In the form shown the vertical shaft 13 carries two discs 24, 33, and a hollow shaft 12 resting on a collar on the shaft 13 carries a boss 4 supported by arms 11. The boss is shaped to form annular passages 6, 10 inside conical hoppers 1, 7. The lower parts of the hoppers are firmly fixed to the hub 4 by arms 5, 8 and the upper parts are made in sections 1a, 1b hinged to the lower parts. These sections rest against fixed rails 21a which permit each section to fall once or twice during each revolution of the apparatus. Unscreened coal is fed into the hopper 1 from the tippler 40, and the largest coal is discharged by the falling sections 1a, 1b into the shoot 41 for storage. The remainder passes through the annular passage 6 to the second hopper 7 where the large coal and stones are discharged by the falling sections into the shoot 36 which conveys them to the centre of the separating disc 33. The small coal and stones pass from the hopper 7 by the passages 10, 22 to the disc 24, the passages being of such size that the constituents strike the disc individually. The peripheral portions of. the discs may be steeply inclined, or the central parts of the discs roughened by perforations or by other means. A barrier 26, Fig. 2, is fixed above the plate 24 to guide the coal to the edge while allowing the stones to pass underneath. The coal passes to the shoot 35 while the remaining material is brought back by guides 27, 30 to the centre of the. disc for further treatment by means of plates 31, 32. The separated material at the centre passes to the second disc 33 from which it is discharged through openings 33a. The disc 33 is similar to the disc 24 and it separates the material supplied through the shoot 36.

Abstract: 466,791. Typewriters. EVANS, O. (Olympia Buromaschinenwerke Akt.-Ges.) Dec. 4, 1935, No. 33603. [Class 100 (iv)] Relay-type-lever actions.-The selected typelever is raised into proximity to the platen by means of a driving-shaft, and impression is effected silently by co-operation of the typelever with a rotating pressure-device which is arranged in front of the printing point and is driven in synchronism with the driving-shaft. In the action shown in the Figure, the type-lever 6 is provided at each side with a stud or roller 7 for co-operation with an impression-cam 2<a> on a shaft 3 geared to the driving-shaft 8. The type-lever is connected by means of a bell-crank 9 to a bell-crank 10 co-operating with an eccentric 18 which is frictionally coupled to the driving-shaft by means of a spring- urged block 34. The eccentric is provided with a spring-urged pawl 19 for co-operation with teeth on the driving- shaft. The pawl is normally held in disengaged position by co-operation of a lug 19<a> thereon with a lug 21<a> on a spring-urged bell-crank 21. A latch 24 for the bell-crank co-operates with a dog 26 which is pivoted on the key-lever 25 and co-operates with an adjustable abutment 28. During one revolution of the driving-shaft the cam 2<a> makes as many revolutions as there are teeth on the driving- shaft. On depression of the keylever, the latch 24 is depressed, the bellcrank 21 rocks forwardly, the pawl moves into the path of the driving-shaft teeth, and the eccentric commences to rotate. An abutment 30<a> prevents premature engagement of the pawl with the teeth, and the friction-coupling 34 prevents shock. During the latter part of its revolution, the eccentric restores the bell-, crank 21, the lug 21<a> gradually releases the pawl from the driving-shaft tooth, and at the end of a revolution the eccentric is arrested by co-operation of the lugs 19<a>, 21<a>, the friction-coupling 34 preventing shock. During the first part of the revolution of the eccentric, the type-lever is raised into proximity to the platen, springs 12, 13 causing the type-lever to move at a uniform speed. The studs 7 then co-operate with the cams 2<a>, and the type-lever is advanced to effect impression. After impression, return of the type-lever is initiated by a tappet 2b on the cams, and is completed under control of the eccentric.
