Abstract: 10,236. Stone & Co., J., and Maccormac, E. C. April 27. Travelling-carriage apparatus.-Reciprocating sprinkler devices adapted to travel over filter beds are provided with oscillating trays, the delivery edges of which are cut so that portions of the beds are allowed to rest for a time. The reversing motion used on the machine is fitted with spring gear to secure quick action. Fig. 1 is a front elevation, and Fig. 2 a plan of a distributor. An axle a carrying track-wheels b and a suspended trough d extends across the bed. Fixed to the trough are frame members f, e supporting track-wheels g and guide-rollers m. A horizontal feed pipe p is supplied from the channel n and delivers liquid to the water wheel v, Figs. 1, 2, and 3. The wheel delivers to the trough d which is fitted with distributing- pipes y leading to the oscillating trays z. The front and rear walls are provided at intervals with T-shaped openings, the openings in the front face being opposed by blank portions on the rear face and vice versa. Stops 6 are provided for limiting the angle of tilt. Abutments 8 are fitted to the trays and engage stops at the ends of the bed for reversing the tilt of the trays. A pinion 9 fixed to the shaft 10 of the wheel v gears with another pinion 11 mounted in a support u. The rocking lever 12 is pivotally mounted on the spindle of the transmitting-wheel 14 and carries the wheels 17, one of which engages with the wheel 14 and the other engages either the wheel 9 or the wheel 11 for reverse drive. The wheel 14, which may therefore be operated in either direction according to the position of the lever 12, operates the wheel 15 on the axle a. Stops 18 come against spring buffers at either end of the filter bed to secure the reversal of the driving-gear. In the modification shown in Figs. 5 and 6, the framing 19 of the distributor is carried by central bearings 20 upon track wheels 21. The framing 19 carries the trough d which supports the wheel v through bearers 22. The tilting tray is divided into three parts 24, 25, 26. The reversing of the trays and of the gearing is effected simultaneously by the operation of the rod 30 having spring buffers 31 at each end. The shaft 27 of the trays has an arm 32 fixed thereon, this arm being pivoted to the rod 30. The rocking lever 12 is extended and pivoted by a pin 34 to the rod 30. Hoops 43 are placed around the buckets of the wheel v to keep them in position. In some cases an independent power motor for effecting propulsion may be fitted as shown in Fig. 7. An endless rope 45 secured to one point 46 on the carriage of the distributor passes around a driving-drum 47 and a pulley 48. The automatic reversing-gear may be similar to that already described, as indicated by the pinions 9, 11, 17, and the rocking lever 12 may be secured to an endless rope 51 passing around pulleys. A second lever 53 is secured to the rope 51 and the lower ends of the levers 12, 53 are engaged by the spring buffers 31. In all forms the trough d may be dispensed with and the liquid fed direct to the tilting trays.
