APPARATUS FOR COOLING BEER.

SPECIFICATION forming part of Letters Patent No. 394,921, dated December 18, 1888.

Application filed July 13, 1887. Serial No. 244,155. (No model.)

To aZZ whom it may concern,.-

Be it known that I, ALBERT I-IALLOWELL, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Apparatus for Cooling Beer and other Substances, of which the following is a specification.

My invention relates to that class of beercoolers where hot wort is cooled by being sprayed into the atmosphere or submitted when in a finely-divided state to the action of air; and its object is to provide a more satisfactory and less expensive apparatus than has hitherto been available for the purpose of carrying on this process.

My invention is illustrated in the accompanying drawings, in which-- Figure 1 is an elevation, partly in section, of a portion of a wort-cooling apparatus, showing the manner in which a number of spraying devices may be attached to a single pipe and simultaneously controlled at a single point. Fig. 2 is an elevation, partly in central vertical section, of one of the spraying devices shown in Fig. l, showing the rack and the support therefor, which is there illustrated as being used to adjust the position of the spraying-cone of the device, and is the view seen when looking to the right at the line a b in Fig. 1. Eig. 3 is a plan of the ring at the bottom of the spraying device, and which serves to support the spraying-cone. Eig. a is a view of a portion of the rack that is sometimes used to adjust the position of the spraying-cone. Fig. 5 is a plan of a ring which is sometimes clasped around the main cone-support, formin therewith an air-chamber. l; is an elevation ol' a piece that I sometimes use to clamp upon 'the rack-carrying rod to limit its motion in one direction. Fig. 7 is a section at the line c d of the cross-bar of the spraying-cone supporti11g-ring.

Similar reference-uuml)ers rcler to similar parts in all of the views.

I make use in my invention of the wellknown principles that evaporation takes place very rapidly among very line particles of Vliquid 'when freely exposed to the air, and that in consequence of this evaporation large quantities oit' heat are absorbed in changing the liquid to vapor. This heat may be absorbed both from the unevaporated liquid and from the surrounding air, in which case the temperature of both is lowered in the operation. It is well known that this evaporation ceases when a certain deiinite amount of vapor has been absorbed by a given volume of air, and that in order to make the operation continuous it is necessary to allow a free access of unsaturated air to the spray that is produced or to remove from the surrounding air the vapor that is produced. Fresh and unsaturated air may be provided in making Ause of my invention in any of the usual Ways which have been hitherto adopted-such as placing the spraying apparatus in the open air or in a space freely communicating therewith when the liquid only is to be cooled, placing' it in a chamber into which air is forced by a fan, or by placing it in a chamber through which air is drawn by a fan or other equivalent means, since my invention relates more especially to the means of producing the spray. I sometimes, however, make use of a special means, hereinafter set forth, of supplying a portion of the requisite air to the apparatus.

The sprayingl device here illustrated may be used either singly or in connection with others of the same construction, as shown in Fig. 1, and an important element in its construction is that which provides means of adjusting from a distance the position of the lsprayf'producin. cone, although this element may in some cases be omitted with advantage.

The spray-producing device is clearly shown in Fig. 2, where the main delivery-tube 1 is shown as having a valve-seat formed in its lower end and as pr vided with means of attachment lo a nipple that is connected io a li(Luni-supplyingpipe. The packing-washer 2, or equivalent means, prevents leakage at the point of attachment. The main conesupport is shown as engaging with the eX- terior of the tube l. by means of a screw-thread, which serves as a means ot adjusting the longitudinal position of the said cone-support upon the said tube. The main cone-support is shown as having formed upon its surface a gear-wheel whose teeth are shown at 4, and

IOO

which engage with the teeth upon the raek 5, that is supported near the sprayiiiig deviee in some Convenient manner. I n the ease illustrated t-he raek is sup]j)orted by the rack-support (i, that is supported upon the top ot the main delivery-tube l, and iixed thereto by the setserew A screw, 7, provided with a cheek-nut maybe used, as shown, to keep the rack and the gear upon the main eone-support engaged with eaeh other, and to allow them to be disengaged at will upon retraeting the sei-ew. 'hen it is desirable to do so, this raek and gear maybe dispensed with and the main eone-support turned direetly by the.

hand ot' the operator ot' the apparatus.

Upon the bottom ot' the main eone-supljnnt is shown secured the eene-supportiing ringl fl, that provided with the eross-bar l0 and the eentral ring, 1l, in which the spraying-Cone l2 is supported. The spraying-cone is made so that it detleets the entire amount of liquid that is discharged alon its surface and dif- :t'uses it into the air below and out-side oli' its base, and is loosely supported in the ring ll, and is preferably made ot suehan aeute angle that the liquid detieeted from its surface will not strike the under side ot' the eene-support The eross-bar i() is preferalrly made as shown in Fig'. 7, in order that the spray' may be readily divided to pass the cross-bar without being splashed about the apparatus. upwardly-sharpened shape of the eross-bar is also desirable ou aeeount of the faet that the liquid does not issue in streams so mueh asit would were this bar t'orined otherwise, and I have found it very desirable to prevent, as mueh as possible, the Yformation oli' sueh streams.

The spray-produeil1g del'leetor l2 is shown as a true eone; but' it is not necessary that it should be so shaped, sinee the requirements ot' the apparatus 'will be met it' the lower portion thereof, at and below the pointy where it touehes the valvesseat in the tube l, be nlade to tlare outwardly Yin sueh a manner as to throw the spray outwardly to a considerable distanee as it `talls.

I sometimes make use of an air-eliamber that is made up ot' the halfa'ings l 4, held together bythe serews i123 or other equivalent means, one of the hal t'-rings being provided with the pipe l5, the whole fitting loosely around the main eolie-support itl, which is then provided with holes 17, leading` from the interior oli' the air-eliamber to the lower side of the support E3, as shown. A pipe, lli, at,- taehed to the pipe l5, li'orms therewith and with said air-ehambei.' an air-eomluit which leads from the air-chamber to some suitable means ot' supplying lfresh air. In the ease illustrated in. Fig. l the airW is shown as provided by a li'an, 1S, whieh leads air from outside the room where the spraying deviees are placed, and t'orees it through the pipe lt) to the pipes liti. The pipes lll should either be flexible or eonneeted to the ring it in sueh a manner that the main e 'n1esu ])]ort f3 will not This l be ilnpeded in its longitudinal motion bythe pipe iti. The lan, the pipe ltr, and the ring` lt maybe dispensed with sometimes, as may also the holes Vl7, while at other times the fan may be dispenset'l with and the pipe lt) led direetly out oit' the ellam'ber in whieh the apw Imratus is plat-ed to a souree ol.l supply ot' tresh air. In the lat ter ease the lresh air will be drawn into the splaving deviee in Considerable amount' by the induetive aetion ol the liquid eseaping therel'rom. l

In Fig. l is shown at ISO a slnaying deviee having the holes l7, but with no means ol' ln'inging air thereto l'rom without the ehamber where the apimiratus is plz'tetwla (-ilnistruetion whieh might be advantageously adopted when the apparatus is to be used in the open air. I do not,lngnvever, usually supply a very large proportion ol' air through the holes V17, when emnpared with the total amount whieh should be supplied.

When a number ol these sln'aying deviees are to be used together, as shown in Fig. l, they are preferably screwed Vupon nipples lf that are seeured to a main liqud-sumily pipe, 2t), and, the raeks whieh turn the main eonesi'ipl'torts 3, attached to a bar, 2l, that is pro vided with a means by which i t may be read-` ily moved longitudinally with respect to the pipe 2t). This means is shown as a segment ot' a gear, 22, supltorteil t'ronl the pipe 20 by the bar 23, and provided Awith the handle 25.

The mode of operation of this device as follows: The liquid to be eooled is, by some suitable and ordinary means, t'ed into the pipe 20 in sueh a manner as to maintain thtwein a eonsideral'lle pressure. The main een, supports are then revolved su t'tieiently to slightly remove the spraying-omnes l2 l'rom the valveseatsin thebottom ot' the tubes l. The 'liquid in the pipe Btl will then tlow out, be del'leeted over the eones l2, and thereby elian ged Vinto a spray, whiefh will. lall into a suitable tub or vat, 27, placed to reeeive it. lvaporation will at onee begin when. the liquid leaves the eone l2 and continue until the liquid is materially Cooled; and I have :found that it Vis easy to thus alrstraet enormous amounts ot' heat from het wort i n a very short time. This action is aided by the air, whieh is sometimes l'oretnl through the holes l7 upon the liquid that passes over the surface ol the eone l2.

Should it at any time be desirable to stop the flow ol the liquid throi'lgh the spraying deviees it may be done by bringing the eone tightly in eontaet 'with the valve-seat in the bottom ot' the tube l, by rotating the main eone-sl'lpiuport in the proper direetion.

In order to make allot' the spraying d eviees elose simultaneously and tightly, 'it' neeessary, they should be ar'ljusted at .tirst by elos'ing them all beili'ore the raelc o is put Vin plaee. They will then remain adjusted with resl'ieet to eaeh other in operation.

I have found. it desirable to periodieally .tlush these spraying deviees, and thus remove any sed iment or solid substanees whieh, 4beingl IOO IIO

in the liquid, collect in the delivery-tubes. I do this by quickly opening the spraying devices quite widely and then quickly bringing them back into the operative position, all when the pipe 20 is full of liquid under pressure. The sediment is thus blown out and the delivery-tubes left free. In .order to make certain the proper replacement of the cones after flushing, I sometimes make use of the adjustable stop QS upon the rack-bar 21,011 an equivalent device, which, striking upon some stationary obj ect--the rack-support 29 in the case illustrated-limits the motion of the rack and enables the operator to quickly bring the cones to the proper operative posit-ion.

I have sometimes found it desirable to swing the pipe 2O upon its axis a few degrees in order to deliver the liquid nearer the middle of the tub 27 than it would otherwise fall, and the structure illustrated in Fig. l is especially arranged to allow ot' this swinging without trouble.

I sometimes place several pipes, 20, with their attached spraying devices over a single tub or vat.

I am aware that some parts of my invention may be advantageously used with other devices than those which are shown in the drawings; and consequently I do not desire to limit myself to making my invention in all respects exactly as there shown.
