i This invention relates to apparatus for handling'mixturesof solid and liquid material and more particularly to an apparatus for handling mixtures of ash and water,

such as are produced by the use of water in I removing ashes fromifurnaces.

- An ObJGOt ofthls lnventlon is to provlde means fordiluting-mixtures of solid liquid material, so that the-resulting mix- Another object is to provide means preventing thesettlingjof solid material 'carried by a liquid thatfclogging of the apparatus will be prevented, I

1 Another object isto'providea reservoir into which a mixture of, solid and liquid material may be delivered and from whichit may be pumped with-means for-maintaining voir between predeter'm'inedlimits. 4 Other objects 'will'hereinaft'er appear; 11 The invention will beibetter [understood from a description of one practical embodiment thereof illustratedfin the accompanyinjg drawings, in which; i v

F'g; 1 is aplan" view of an "ash handling apparatus in Which the invention is embodied.

Fig. 2 is a longitudinal section of the apparatus shown in Fig. 1, and, Fig. 3 is an elevation of a modified form of sump and pump.

A reservoir is shown at 1 and is provided with downwardly converging walls 2, one of which may be vertical, a'bottom 3, and vertical walls 4 extending upwardly from the upper edges of the converging walls. Within the reservoir and substantially at the top of the inclined walls 2 are positioned horizontal gratings 5 extending over part of the upper surface of the reservoir.- Around the horizontal gratings, upwardly extendingver-" tical gratings 6 are provided. Two pipes 7 are shownas discharging into the space above the horizontal and within the vertical gratings and convey into this space mixtures of ashes and water brought from boiler furnaces or the like through suitable sluiceways 8.

The mixture of ashes and water passes downwardly through the gratinginto the botthe level of thefluid mixture in said reser-f} tom ofthelreservoir. j Largev pieces 0f" ma terial will, of course, notpass between the bars and such pieces, therefore, remain upon Y the grating.

As seen'in EigIZEthe nozzle 11 directs the jet of high pressure =wa1ter in a; direction opposite tothe flow of the niiXtureWO throu oh the outlet conduit 9; This high pressure jet agitates the mixture as it entersthe discharge conduit and prevents thesolid inaterial from settling at the bottom ofthe hop 3 peradja'cent' the conduit9. The grating has itsbars' so spaced th-at' 'pieces oit'-material =which are toolar'ge for pump- 10 to'handle willbe'retained uponEthegratinsrbars.

Within the reservoir is secured a vertical; casing 12', in which a float-13 is adapted to so 'ino'vel The float is connected by rods to a V lever arm IA which operates an angle valve 1'5 'which'controls a water supply line16 for admitting'water to the hopper. This supply;

A con; 7 trol 21 'is provided by which both motors are started andst'oppe'd and which preferably has H an'automatie'relay so that the sluice pump will not start until the reservoir pump has been started. A switch 22 also be inserted in the power line to motor 19 and may 7 be operated by the movement of the float so that when the water level in the reservoir drops below-a predetermined point, the reservoir pump will lee-stopped and remain so until the levelreaches any desired pointl In Fig; -3-,'an inlet tothe reservoir pump is shown which consists of air Yfitting 9, the branchingf-armbf which is connected to I the pump.
