Nrrn era GEORGE A. SIMS, or ERIEQPENNSYLV NIA, AssIGNo ERIE, PENNSYLVANIA.

I v ia ea TO THE s rMs' COMPANY, or

REVERSIBLE Hnri'rrN-s on cooLrNe'ArrAitArUs;

Application filed August 26, 1922. Serial No. 584,559.

SIMS, a

Pennsylvania, have invented certain new and useful Improvements in Reversible Heating or Cooling Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same, panying drawings, erence marked thereon, specification. V

This invention relates to reversible heating and cooling apparatus, and the object and to the letters of refforming part of this thereof is to provlde means whereby a heat or cold bearing fluid is caused to flow through a plurality of tubes which extend through a chamber which contains the fluid to be heated or chilled, and in providing means within said chamber adapted to cause the fluid to be heated or chilled to flow in successive and alternate transverse directions with relation to said tubes as it progresses from the intake to the outlet of said chamber." I

To accomplish this I provide a hollow cylinder in which I place a series of discs transversely within the cylinder, these discs being provided with spiral flanges which space the discs apart. Each alternate disc is provided with a central opening, and the next adjacent disc has a portion of its periphery cut away thus forming a notch therein, so that the fluid to be heated or cooled passes through said notch and then in a spiral course to the central portion of the chamber, and then through the central opening in the next disc, and then in a spiral course to the outer porton of the chamber, and so on in alternately reversed spiral directionsuntil the exit from said chamber is reached.

These and other features of my invention will be hereinafter pointed out, and are illustrated in the accompanying drawings,

in which:

Figure 1, is a side elevation of my reversible heating and cooling apparatus, with a portion of the shell broken away.

Figure 2, is a vertical section of a'frag ment thereof showing the construction of the ends thereof,

residing at reference being had tojthe accom- *igure 3, is a transverse section thereof on the line 3 3 in Figs. land 2. u Figure 4:, is alike view on the line 4 -4: in Fig. 1. V Figure 5, is a like view on'the line 5-+5 in Fig.1.

, Figure 6, is an e'dgewise elevation of one,

of the discs which form divisions within the cylinder shell. I

Figures 7 and 8 are side elevations of two of said discs turned fromeach other showing the meeting edqes'of thespiral flanges thereon. E

Figure 9, is an'edgewiseelevation of one of the end" or terminal discs, having, the spiral flange on one side thereof: widene-d as hereinafter described;

In these drawings drical shell having each end thereof. Within this shell A I place a plurality of discs B and B, the discs B being cut away as shown at b in Figs. 5

A. meats. an...

flanges out-turnedv at and 8, and the alternate discs B having a central openlng b therethrough as shown in Figs& and 7. I 4

These discs B and B are provided with identical spiral flanges b on their adjacent faces, which space said discs apart as shown in Figure 1,'but also form spiral passages between said discs from the wall of the cylinder inwardly to its axis. 1

At each end of the cylinder A there are formed inlet and outlet openings at and a by means of which the fluid to be cooled or heated is introduced into' and discharged from the said cylinder.

The discs B which terminatethe series at each end of the cylinder are provided with a widened flange b which will space the first disc B at each end of the cylinder A sufliciently inward from theend thereof to provide a chamberinto which the inlet and dis I charge openings a and (1 enter.

The discs B and B are provided with of the cylinder a header chamber E is secured which'encloses therein the ends of all the tubes C. These header chambers E arev provided with inlet and outlet pipes F and F by means of whichthe heating or cooling fluid is" introduced and passed through the pipes T 1 spiral flanges If. The heating or cooling In operation the fluid to be treated is introduced into the cylinder A through the inlet a and caused to circulate therethrough and outot' the discharge openinga during which it transversely passes the tubes C in alternately reversed spiral paths formed be tween the'discs B and B" by means of the medium is introduced in. the-iheader F through the inlet pipe F and it travels therefrom through the pipes C to 'the opposite header E and out through the discharge pipe F. It Will be obvious that the con tinuance of this operation of my improved apparatus will eflectual'ly produce a substantially equalization of temperature be tween the fluid introduced into the' l1eaders E and tubes C, andthat circulated through the cylinder A. I

Having thus fully described the construc tion'and operationof my invention, What I clann as new and deslre to secure by Letters Patent is:

1; In an apparatus of the class described, a casing having inlet and outlet openings at opposite ends thereof, a series of transverse Walls thereln, each alternate Wall having a. central opening therethrough and the other alternate Walls having a notch cut out of the perlphery, spiral flanges on the ad acent faces of said transverse Walls, a plurality of longitudinal tubes passing through said casing and through said transverse Walls and secured in plates at the ends of said cas ing and header chambers on the ends or" said casing covering the ends of said tubes.

2. In an apparatus of the class described,

a casing having inlet and outlet openings adjacent .to the ends thereof, a series of tubes passing longltudlnally through said casing and secured in the end Walls thereof, aseand,

ries oftransverse Walls in said casing, spiral flanges on'said transverse Walls spao ing the same apart; i

3. In an apparatus. of the class described,
