JOSE-PH SHACKLETON, OF RAHWAY, NEW JERSEY.

Letters Patent No. 87,301, dated February 23, 1869.

IMPROVEMENT IN STEAM-HEATERS.

The Schedule nefen'ecl to in these Letters Patent and making part of the same.

Be it known thatl, .losnPH SHACKLETON, of Rahway, Union county, State of New Jersey, have invented a new and useful Modoof Utilizing the Exhaust Steam of Engines to Heat Buildings, and for heating dyers kettles, soap-boih'n's, and the various purposes wherein live steam is now employed; and I'do hereby declare that the following is a full, clear, and exact description of the mode or system employed, reference being had to the annexed drawings, making a part of this specitication.

Figure 1 represents a cross-section of a building, with the location of the boiler A, engine B, steam-pipe O, exhaust 1), by-pass W, supcrheating-pipes H, heatingupe J, and heatin -series M M, N N also, boilerheating pipe K and L L L.

P l are crnnleusing-pipcs. Y

O is the return condensing-pipe, leading to the tank or boiler-feeder R.

G is a back-pressure gauge.

lfig'ill'e 2 represents the automatic or self-acting exhaust-valve, which is placed on the exhaust-pipe at F.

The 1 peration of this system of heating, by exhaust steam, consists in conducting the steam, after it has actuated the engine, into the superheater H, where it gains a greatly increased temperature.

It is then passed, 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 ketties, and the various heating purposes for which steam is ordinarily employed.-

After the steam has made its circuit in the series of heating-pipes M M, N N, 850., it becomes condensed, and flows back, tln'mlgh'pipes P P and O,into tanlc or feeder ll, in the form of pure distilled water of a high temperature, which is again returned to the boiler, thereby saving fuel and preventing inerustation in the boiler It will be observed that the exhaust-steam is superheated by the waste heat of the furnace that heats the boiler, at little or no extra expense for fuel.

\Vhen the engine Bis not at work, valve E is closed, and steam is taken directly fromthe boiler A, through the by-pass pipe \V, and passed through the superhoater in the usual manner, to supply the heating-system.

The automatic valve, at F, more fully shown at fig. 2, is managed with a spiral spring in stem 1, which holds the valve to its seat.

Screw V regulz'ttcs the tension of the spring. The oflice of this valve is to open when the back-pressure is too great, and give direct exit to the steam, and prevent reacting upon or stopping the engine.

By this system of superheating and utilizing exhauste steam, twenty-five per cent. of fuel may be saved.

Having thus-described my system of heating by ex haust-steam,

\Vhat I claim, and desire to secure by Letters Patent of the United States, is-

1. The use of superheated exhaust-steam for heating buildings, and other purposes, as above mentioned.

2. The utilizing the waste heat of a steam-boiler to supcrheat steam for heating-pur mses, substantially as and for the purposes set forth.

3. The combination of a system of heating'by exhaust-steam, substantially as described, with the condelwing-apparatus, substantially as and for the pur-. poses described.

4. The combination of automatic valve F with the superheating and heathig apparatus, substantially as and for the purposes represented.
