O is the return condensing pipe leading to the tank or miler-'feeder 1t.

G is a back-pressure gauge. Figure 2 represents the` automatic or selfexhaust-val\ 'c,

acting which is placed on the exhaust-pipe .lhe operation of this s steam consists in conducting the steam alter it'has actuated the engine into the reheater or superheatcr H, where it gains a'greatl y incleased tcmpeiaturc.

It is then missed through pipe J into. the series of. heaters M M N N K L L L where'it radiates its surplus' heat, to warm buildings, or to heat dyers kettles, and the various heatj' g purposes for which steam is ordinarily employed.4

The sulufrheater H consists of a seriesof pipes Il, connecting at their ends with and opening into lthe ehambefed heads h'fh", so arranged as to allow the pipe j, through the head h",'pipes h, head h', into the pipcJ, thus exposing the steam to a'largc amount ot' iire-surface, rrhh-li rapidly elevates its temperature. l

Alter the steam has made its circuit in the serie of inenting pipssM MN N, &c., it becomes condensed and flows back through pipes P I and 0 into ankor re distilled water oi a high tempelature, which is again returned to the boiler, thereby saving fuel and preventing incrustation in the boiler.

lt'will be observed that the exhaust steam is rcheated by the waste heat of the furnace lthat heats the boiler, at little or no extra. expense for fuel.

I and steam is taken directly from the boilerA through .in thc usual manner to supply the heating system.

The automatic valve h referred to consists of a. shell, A', fig. 2, the same being provided with an in` which is threaded to admit of its attachment to the exhaust-pipe. Within said shell is a valve-seat, B', to which is .iittedjthe Avalve C', attached'to one end of the guidestem D', projected through ascrew-eap, E', secured in the opening F' ofthe shell A.

- T is a tube, one cud of which is screwed to the boss 'of' the. cap Ei In said tube is a spring, T', the position of which contact therewith, and by it exerts its resistancy upon the valve, thereby keeping it closed. The tension of the vspring is graduated by theadthe tube and manipulated by the hand-wheel Vi The practical operation ot' this valve is as follows, viz:

-By means of thethreaded boss openings referred steam heilig admitted tothe shell through the opcn` ing S', passing thence through the valve, and from which it estampes through 'the opening S into the continuation ofthe exhaust-pipes.

valve is grad uated by the/adjusting screw V be required in' order to 'acccomodatc they valve to a variable. pressure-of steam.

variable pressure of steam in the 'manner described renders the valve applicable to engines of dii'erent capacities, and also enables thel operator to correct Vany'wealmess ofthe spring which may result from its wearing. l

What I claim, and desire to secure by Letters Iatcnt ot the United States, is-.

The combination oi' an automatic compensating valvewith an apparatus foireheatiug and heating, as and for the purpose substantially as described. JOSEPH SHACKLETON. Witnesses:
