EDXVDI F. PORTER, i3 BOSTON, MASSACHUSETTS, ASSIGNOR TO THE BAY RAT Li 5 SPEGXEICA'IIUN f rming part of Letters Patent No. 664,776,

dated December 25, 1900.

Application filed December 20, i897. beriol No. 662,541. No model.)

To (4U i Ii /tom it may concern.-

.1) 2 known that I, EDWIN F. PORTER, a subject of the Queen of GreatBritziin, resid-' ing at Boston, in the county of Suffolk and State of lilessoehusetts, have invented certnin new and useful improvements-in Apperntus for Cooiing rind AgitatingAir, of which the following is n specification.

My invention relates to an apparatus for cooling nnd agitating air; and the object is to cool air by the action of an electric current in 2i thermopile the action of said current displacing heat from one end of the electric conductors to the other, thereby cooling the air in contact with the end from which the has been taken, niter which the heat whic is stored at the opposite end is curried ewn .y n current oi water. The ziir after being cooled is blown from the cooling-sur- 1 es by there'vo tion of fen-bierlesin which the cooling surl' areincorporated, and in this wzty the temperature of the z'i-pnrlment in which the lei-ll s iced is lowered.

My invention consists of certain novel features hereinufier described, zuul pnrticuhi-rly pointed out in the claims. p

In the acconipzinying drawings, which illustrate acoustruction embodying my invention,

Figures 1 and :3 represent, respectively, sii'le and front views of on hpp iwitus for cooling and imitating;- air. Fig. 3 is a sectional View through two 0 osiie fembiudes and the m0- tor-n.- t is h sectional vieivoi the eii l:ition-ehmnber and motor.

. Like letters 0:? reference refer to like parts throughout the sci ernl views.

A represents e,upon which rests L- poi-at l3, and upon said post is supported it motor 0. "n the front end of the motor-shaft I) there e ured s h ub E, in which are secured four vilo aides which communicate with the riorof theshztlti), nsshown in Fig. 3, and e inner nrough the stu fling-box. G with u Waiter-chumer li, which receives its supply through the ipe ii, having a suitable controllingw'nlve The water entering the chem ber H posses irough the hollow shaft D and enters the ades l and from said hollow blades end cl Stl'i slmft D communicates through the inner tubes F to the interior of the inner hollow shaft 1, which passes rear.- wardly through the stuffing-box J zind communicates with the wnter-clmnibcr J on one side of the partition J which seperntes the weterweceiving chamber H and the Wateroutlet chamber J. The water entering" the chamber J passes oii. through the pipe K, having a suitable valve K, elfectin r in its eircu lation the coolingof lhe innerside of the thermopiie L, hereinafter described.

' Mounted on the front of each blade of the fan is a, therinopile L of the ordinary construction and securely fastened to the front side of each blade, and a wire conductor M supplies the current to the brush M, which current passes to the collector-ring M mounted on the insulating-drum M The current passes through the wire M in the insulating drum M, and the wire is connected with one pole of the thermopilo L at M. The current passes through the thermopilo and out through the wire ii back to the other collector-ring M and thence to the brush M and to the Wire M", which completes the circuit. The inner shaft I being secured fast at its fronteml lo the outer shaft D revolves with said shaft as said shaft l) is revolved by the electric motor (2, which may be of the ordinan-y construction, and in the revolution of the outer shaft D the brushes M and M are kept in constant contact with the collectorrings N' and N and thereby supply the thermopile of each fen-blztde with an electric cur-- ren t.

In this device the object is to cool the air in an apartment by means of an electric current, and this cooling is effected by passing a. current through H, therniopile of the ordinary construction. lhe current in passing vill remove the heat from the outer joints L of the thermopile to the inner joints L and the heat which has been thus displaced by the current is then carried away by a current of water; which circulates against the inner surfacesof the hollow blades with which the inner joints of the therinopile are in contact. The thermopile is soldered on each blade and is therefore an integral part thereof and form:

the cooling-surfaces which come in contact with the air, 'and it is obvious that the fan in revolving will cool the'air of the apartment in which it is located, and the cooled air will be rapidly diffused or carriedaway from each blade upon the operation of the fan.

It is obvious that the entire fan-blade may be formed of the thermopile so arranged that the water will come in direct contact with the inner joints of the thermopile, to which theblade, means for circulating a fluid through said hollow blade,

a thermopile contacting with the face of said blade, and means for supplying electricity to said thermopile. I

2.. In an apparatus of the character specified, a fluid-supply chamber, a fluid-receiving chamber, a hollow shaft, means for rotating said shaft, a fan carried by said shaft having a hollow blade, passage-ways connecting said chambers through said hollow shaft with said hollow blade to circulate a fluid through said blade, a thermopile contacting I claim as new, and

with the face of said hollow blade, and means for supplying electricity to said thermopile. y

In an apparatus of the character specified, a rotatable shaft, a fan carried by said shaft having a hollow blade, means for circulating a fluid through said blade, a thermopile contacting with the face of said hollow blade, collectors carried by said shaft, brushes electrically connected with a source of electricity engaging with said collectors,- electrical connections between said collectors and said thermopile, and means for rotating said shaft.

4-. In an apparatus .of the character fied, a flnid supply chamber, a fluid-receiving chamber, a hollow shaft, means for rotating said shaft, a fan carried by said shaft having a hollow blade, passage-ways con meet ing said chambers through said hollow shaft with said hollow blade to circulate a fluid through said blade, a thermopile contacting with the face of said hollow blade, collectors carried by said shaft, brushes electrically connected with a source of electricity engaging with said collectors, and electrical connections between said collectors and said thermopile.

speci- In testimony whereof I have'signed my name to this-specification, in the presence of two subscribing witnesses, this 18th day of December, A. D. 1897.
