MERCURmL-EXPNSIN ENGINE.

.Tnefseheavle :ermetico m time naam name ma making pm aras same.

Bc it known that l, CHARLES G. Winsox, of Brooklyn, in the county of Kings and State'of New York, have invented a new and useful lmprovemeutin Mer-1 curial-expansion Engines 5' and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable others skilled in the art tomalie and use the same, reference being had to the accompanying drawing forming part of this specification, in which--4 u Y Figure 1 is a side View of my improved engine, partly in section through the heating-trough.

Figure 2 is'atopl or plan viewof the same.

Figure 3 is a detail sectional View, taken through .the line x x, iig. 1.

-A is the crank-shaft, to which motion is given by ythe engine, and 'li'om'which motion is communicated to the machinery tobe driven by an ordinary gearing.

Upon the shaft A isformed four or more cranks, a', arranged at"1igbt or equalangles with each other, as shown in tigs. l and 2.

I- To the cranks c' are pivoted the outer ends ot' the pistons B, which enter and work in the tubes G.

The tubes C are provided with trunnions formed 'upon or attached to them, which work in bearings attachod to the upper ends of the standards D, the lou-er ends of 'which are adj ustably bolted to the bed of the machine, so that they may beadjusted as required. y

The other ends of theA tubes O are screwed .upon the bases ofthe nozzles E formed upon or attached to the forward edge of the hollow cross-heads F, with the rear side edges of which are connected the ends of the coils G. y I.

Seven, more or less, coils Gare connected with each hollow cross-head or cylinder F.

The shape of the coils G is immaterial, so long as they are so formed that, as the tubes G oscillate, the bodies ofthe coils may descend into the trough H, as shown in iig. 1. I The forward or end parts of the nozzles lt are made smaller than their bases, and th'c outer surface of said smaller parts is corrugated or ronghcncd, to enable thc India-rubber.tubes or bagsI to be wired, or otherwisc securely attached, to said nozzles;

The other ends of thebags I are closed andV rest against the ends ofthe pistons B, to prevent the contents of the coils from escaping around the said pis- Itons, while, at the saine time, allowing the said con'- teuts to expand and contract freely.

The trough H is lled with brine; anu beneath it should be placed an ordinary furnace, or other heat'- ing apparatus, so -that the said brine may be kept heated to about two hundred degrees (2009) Fahrenheit. v

The coils G are filled with mercury up .to the pistous', the rubber bags I preventing 'said mercury from coming yin contact with said pistons, and from escaping through the tubes 0. f By this construction, one' or more of the coils G will always be in the trough H.- v As the mercury heats it expands and forces `out the piston B, revolving the crank-shaft A ,through about a quarter .of a revolution .At the sanietime the:

pistou B andA tube C act as 'a lever to raise' the coil G out of the trough vH. As the coil G risesout of the trough H the rapid evaporation fromits wet surface quickly cools the mercury, which contracts and allows the coil to again-descend into the troughH, by its own Weight and by the leverage of the said piston B and tube O.

All thecoils G operating successively in the same way, a continuous motion is given to the shaft A, and

through it to the machinery to be driven.

Other liquids than mercury may be used in the coils G,'provided they possess the quality of receiving and part-ing with heat readily.

The coils G should move through au are of about thirty degrees, (30),of whiehabout sevenv should be in the trough H, and the remaining space'in the air.

Having thus described my i'uvention,

I claim` as new and desire to secure by Lettels 'Patent- 1. Impar-ting motion to machinery by means of the expansion and contraction of mercury, or equivalent heat-conducting liquid or compound, substantially as herein shown and described, and for the purpose setV 2. 'lhe combination of the clank-shaft A a', pistons B, tubes (l, rubber bags I, hollow cross-heads F, coils G, and trough H, with each' other, substantially as herein shown and described, and for the purpose set forth.

vrlhe above specification of my vinvention signed by mcvths 23d day of' December, 1869.. O AS. G. WILSON.
