The cinders which are deposited in the cinder hopper, 6, are discharged therefrom by the suction 'nduced. by the exhaust blast, by which they are drawn into and throu h a 10 cinder cooling conduit and ejected therefrom throughthe exhaust nozzle, 64;. In lieu of using, as a cinder conduit, a pipe of considerable length, extending first rearwardly from the cinder hopper and thereafter forwardly to the exhaust pipe and nozzle, as in the application Ser. N o. 47 1,262 aforesaid, I provide said conduit in the form of a plurality of return bend, or alternately reversely extending, passages or channels, 11, which 2 communicate at alternately opposite ends, so

as to form a continuous conduit. Said passages are preferably of rectangular section, and are formed in a radiator casing, 11, which is secured detachably to the cinder hopper, 6, over anopening in the vertical front wall thereof. The radiator casing, 11., is a box or chest of cast or'wrought metal, of substantially rectangular transverse section, and having openings in its ends, the

rear opening registering with a corresponding opening in the front of the cinder hopper, and the front opening being closed by .a removable cap -or cover, 11. The bottom of the radiator casing is located a short dislance above that of the cinder hopper, and a deflecting plate, 11., projects downwardly and rearwardly from the top of the lowest of the channels, ll", so as to cause the current of cinders to be drawn below said chanuel and reversed in direction before entering it.

The plates or partitions. between the alternately forwardly and rearwardly extending channels, 11 are, for convenience and simplicity of illustration, indicated in Figs. 1 and 2 as beipg formed integral with the body of the casing, but they may, as shown in Fig. 3, be made separate therefrom, either individually or in one or more sets or sections, so as to be renewable when sufliciently worn by the abrading action of the cinders to render renewal necessary or advisable. To more ef ectually resist this abrading action, the plates or partitions, as well as the body of the radiator casing, may, with advantage, he made of special material possessing a high degree of hardness, as, for example, chilled cast iron or manganese steel.

Among the advantages of the formation of the cinder cooling conduit in a register casing, as above described, may be enumerated economy and compactness in the con struction of the ap iiaratusg the avoidance of an additional passage in a cylinder saddle or saddles; facility of renewal of worn or cinders from the hopper,

-the right of way, which has heretofore.

6, through the channels, 11", of the radiator casing, and thence through the pipes, 9, and t ject them, mingled with the exhaust steam, through the stack, 4'. In and by their traverse through the channels of the radiator casing, the. aggregate length of which is considerable, and their admixture with the exhaust steam, the cinders will be disintegrated, reduced in tein-' perature, and extinguished when they are discharged from the stack, and, consequently, risk of fire damage to property adjoining always obtained to a substantial extent will be eliminated.
