The

The remainder of the apparatus is of ordinary construction and only needs a brief description.

and k are the condensing-coils; Z and Z', the liquefiers and refrigerating-surface submerged in brine; m, the overflow; n, the brine-tank; o, a layer ofinsulating material; Q9, p', p2, and p3, ice-molds.

The action of the apparatus is as follows: When the parts are in the position shown in Figs. l to 4, the tank c is raised, the vessel Ct being immersed in it and being cooled. The

burner Z) is beneath and heating the vessel c@ lVater is flowing into the tank c by the cock g and pipe g', and water is flowing out of the tank c by the valve Q'. The seat S of this valve is in a tube S', iixed in the tank and communicating with a spout SZ. The Valve is normally held down onto its seat S by tbe weight T, but it is hxed to a chain R of such a length that when the tank has almost reached its lowest position the chain prevents the valve from descending lower and lifts it o its seat, thus allowing the water to ilow out of the tank through the spout S2. The upper end Aof the chain R may be wound on a spring-barrel V, so that the hanging portion of the chain is kept straight and so prevented from fouling any of the mechanism. The tank c is prevented from descending, although it now contains more water than the tank c', by the stop e', which engages with the end of the tube d. As the vessel d becomes heated the tube CZ tends to straighten, and ultimately its end rises out of the way of. the stop e', thereby releasing the wheelf. The tank c then descends by its superior weight, lifting the tank c, which in its ascent pushes the burner b over to under the vessel a, as above described. The stopesprings the tube d to one side and then engages with its end, so preventing the parts from returning. The wal ter-supply is cut oi from the tank c and diverted to the tank c', and water runs out from the top of the tank c by reason of the valve Q being lifted by the chain R, as described above with reference tothe valve Q'. The parts are now in the position shown at Fig.. 5.
