Letters Patent N 93,840, dated August li', 1869.

IMPRVED COOLING-AND VENTILATI/G-APPARAT-US.

The Schedule referred to in these Letters Patent and making part oil'thk'. same.

To all whom. it 'may concern.:

Ile it known that I, Joux' T. Scuiuaxoicn, oi' .New York, in thc county and State'oi" \'0w York, have iureutcd a new auduscful Ql'loliug and Vcnti|ain; ;.\p paratus; and l do hereby declaro that thc following is a i'ull and exact description of the same, relironr'c boing had to the accompanying drawings, and to the letters oi'rciiu'euce marked thereon.

The chemical and physical changes to which thc nir in closed localities is subjected, either by the respira-V tion and pcrspiring of a number oipcoplc therein cougregated, or in consequence-of m:niurcturhlpg-processes of various kinds, have nol only a material hearing ou the normal state of munis' health, bui; are contributive to his comfort, and iu many instances are of the greatest consequence to preserve the producinf manu lne turing :roux rum.

During the hot, summer mouths, it becomes imperativo to secure the poriiicatiou of the air byvoutilation, :mdio reduce the high rango of temperature, -so as to make it healthy and agreeable,

With this object. in View; :i good many contrivani'es have been resorted to, which, although all moro or less useful in some respects, have still proved deficient, being indifferent-ly constructed, too complicated and costly, and uut for the purpose to be served.

My invention consist-s in constructing a cooling and vent-ilatilig-apparatus in an improved and simpliticd manner.

For this purpose, I provide two chambers, and conneet them by tube-s, and around one of the chambers I encircle acoil'of pipe, which opens into the other one, a suitable discharge-pipe being provided. The parts "may be entirely or partly covered' 'or enclosed within cold water, ice, or. other cooling-material, the

coil couveyiugcold water to the tubes, through which it 'rrickles or sprays, so that the blast oi' air enters one. chaudron-passes into the spray-,tubes into the other chamber, and out at the discharge-pipe, whereby it is subjected to the action of cold, from eut-rance to exit, over a large surface, which occupies but a small sparc, as will be hereinafter more fully described.

lu thc accompanying drawing- A is a ventilator, wherehya blast or current of air is produced, :uid passed into a. box, B, forming part of the refrigerator R.

This refrigerator consists of a great number of" tubes, C, made of thin galvanized sheet-iron or copper, securely fastened to au upper and lower chamber, B and D.

VIn the ripper chamber or box B, these tubes project about nwo inches, and euch tube is made with a small 012,132, fhroi-fh its side near thebot-tom ofthis charm i Bl' r To the bottom or lower chamber D, a largebell- 'fry Leners Patent, is.

shaped pipo, E, is lhstcuod, rising upward, and grudnull)- contuxctins( to iis required size.

lhis apparatus is placed into a chamber or box, F, lille-d with cold water, ioclor any other suitable cool'- ing-substance, surroiunlug; every part oi' the. appuraius'. A

into the box F, a water-pipo, J, is couducted,'passing downward to the boifom, Vand is formed there in a coil, passing sew-ral times around thc lower chamber l'), and thou upward again to the chamber Il, io which s'did pipo. .l is clinched near the bottom. 'lhe pipc'ii from the ventilator' A is connected with ibo upper chamber B.

'lho air from the ventilator A passes into Lne upper chamber B, and passes then through the tubes C into the lower chamber D having been deprived of a conA siderable amount of its-t`em-pemture while. passing through the tubos C, and pass/'cs thon through the ccnl. trai pipe E, from where it is conducted to thc room or place to he cooled and \entilated., i

The air, while passing 'through the tubcstl, comes in contact with a small sheet ol' cold water entering through the holes 2,-iu the upper part of said pipes U within the chamber ll, and receives thereby its required moisture. v

The water passing through these tubes (l is collected iny tho lower chamber l), and is carried ori" through the pipe N attached'to the bottom oi' said chamber D.

. It is evident that ilu` air, allor -hus being exposed io the inllueuceyof a considerable quantity oi' cold water, surrounding thc'tuhcs' C, through which the air is made to pass, as well as to the influence oi' tho cold Waterpassing through said tubes C,and coming in contact with Lheuir while passing through said tubes, must have zit-tained a degree oicooincss answering most purposes. I,

Should a further reduction of the tempemturebe desired, ico in larger or smaller quantities will hare to bc. resorted to. n

During the hot season, when. the outside temperature rises to about 86, Fahrenheit; or more, a rednetiouof from 12 to 18 can generan)Y be effected, eren where the water has a temperature of 54 to GSO l `uhrouheir.

I am aware that'ii; is'uot.'1ie\v.to cool air by subiectihg if: to passage through and over cold water, and that'spmy has been employed tol assisi'l iu the operation.

l. am aware that; air has been passed through tubes, or a, series of tubes surrounded by water or ice, for the purpose of being cooled. the-roby, and 'I do, therefore, not claim this broadly; but

What Iclain as my invention, and desire to secure Th.: appfnatus fur the purga@ crihed, consisting of tubs C O, projerrtmg into nclztng with chamber D, in connes-tion with :L coil, J, for running wntcr, dschnrrge-pipe E, und enclosingcharnbsr F, whereby the blast; enters chznnbcr li, passes through tubes C C, in coutnctwith Water tricklug through them, thence through the water in chann-
