7 HEAT REGENERATOR.

. Application fiiea'nn 'zaf This invention relates to heat recuperators or regenerators, and has particular reference 7 to those formed of firebrick or otherrefractori material. V 7

Heretofore, regenerative furnaces have been formed of a plurality of variously shaped elements which were expensive and diflicult to make and required specially skilled worlnnento erect because of the in ing elements that. can be'readily setup by anyone s tilled in the laying of brick or ma sonry, and in such a manner that weight is distributed amongthe elements instead of being borne by a fewelements. v j

A further object. of this invention'is to provide a regenerator construction such that the joints of the special elements forming the circuits for the currents of gas or, liquid shall be impervious to the SZUHQQ GELCh element co acting with the adjoining interlocking elements to formcollinear tubular passageways having only transverse joints, the several passage-ways for one substance being at right angles to the passage-ways ofthe other substance so as to form a cross-current heat in terchanger.

Other objects and advantages ofthis in vention will become apparent from a'description of a preferred embodiment thereof such as is illustrated in the accompanying drawings in which like reference characters designate like parts in the several views.

In the drawings:

Figure 1 is aperspective view of the special element of which the regenerator is constructed.

Fig. 2 is an elevation of the regeneratorthus constructed, being shown partly in section as seen along line 22 of Fig. 3.

Fig. 3, which is a sectional plan view of the regenerator as seen along the line 33 of Fig. 2.

Referring to Fig. 1, numeral 1 designates register with passa eways 3. ot each row equal to the width of t'enons 2, plus the negl 192s.v Serial No. 125,563.

the symmet-rical regenerator element which is substantially rectangular in form and is providedat two opposite sides with transverse tenons 2, parallel to the common plane of which are passage-ways 3 disposed at eachside of passage-way 4, which is formed in the common plane oftenons2 and at right angles to the direction of passage-ways 3.

.Fig. 2 illustrates the ments 1 are arranged to form continuous pasmanner in which elesage-ways 3in a vertical direction, and gcontmuous passage-ways t and 4* 1n a horizontal direction, passage-ways 4 being equivalents otand parts of the,hor1zontalduct system formed by passage-ways 4 and c'onstitutethe space 'between'the tenons of aligned'elelnents' and the sidesfof adjoining-elements.

As" illustrated 111 F 1g; 2, the regenerator is adapted to be used with a furnace. of'some kind, the hot gaseous products of combustion.

thereof passing through horizontal passageways 4 and? on. their wayto the smokestack, and. the cold air, blast passing vertical- 1 y downward throughpassage ways 3, whereby the air isheatedf by contact withthe hot elements and passesout below as a hot blast to the furnacecomb-ustion chamber or utilized to other purposes. Simultaneously with the heating of the air blast, the flue gases are cooled before passing "into the stack. Fig. 3 illustrates-the arrangement of the elements as seen in plan section, the flue gases passing through horizontal passage-ways 4 and 4 and the airblastpassing through vertical passage-waysfi.

In constructing the regeneratonthe foundation is preferably provided with a not blast duct 6 havingopenin s which are adapted to register with ver ical passageways 3 formed by interlocking elements 1.

asshown in Fig. 2. Finishing slabs 8 may be utilized at the top and base,fand which are also provided with openings adapted to The elements are spaced apartby distances gible space for mortar, and the elements of the second row are likewise spaced apart by the width of tcnons 2 which are fitted into the spaces between the elements of the next lower row, etc. Thus each successive row of elements is displaced laterally relative to the next adjoining rows, so that each element centers with the space between theelements of the next adjoining rows. The projecting portions of the end elements of alternate rows are set in side walls 9 as shown in igs. 2

and 3.

It vwill be evident from the above descrip-;

tion that a simple and eflicient regenerator for exchanging heat or cold between gases, liquids, or gases and liquids, may be readily constructed by utilizing a plurality of the specially-shaped interlocking elements or bricks il i ustrated in Fig. 1. While the regenerator of this invention has been described as a flue'gas-heat exchanger or interchanger, it is to be understood that it may be used for other purposes, that the heating or cooling medium may be alternatively passed through the vertical or horizontal tubes and in either direction, and that changes may be freely made in form and detail without departing from the spirit of this invention within the scope of the appended claims.

What is claimed is:

1. A substantially cubical regenerator element symmetrical about each central plane, tenons disposed upon two opposite surfaces in a central plane, passage-ways through said element in the central plane of said tenons, and other passage-ways disposed in planes parallel to the central plane of said tenons.

2. An element for regenerator construction having tenons formed upon two of its opposite faces,'passage-ways formed through said element in the common plane of said tenons, and other passage-ways formed through said element in planes parallel to the common plane of said tenons and at an angle to the first-named passage-ways.

' 3. A regenerator element having substantially rectangular surfaces, transverse tenons disposed centrally across two of its opposite surfaces, a passage-way formed through said element in the common plane of said tenons, and other passage-ways formed through said element in planes parallel to the common plane of said tenons and disposed at each side of and passing at right angles to the first-named passage-way.

4. A regenerator element having substantially rectangular surfaces, rectangular tenons projecting transversely from two opposite surfaces, a passage-way formed through said element in the common plane of and having a rectangular cross-section substantially equal to the surface of said tenons, and

other passage-waysformed through said elein the next adjoining elements to groups of relatively rectangular passage-' ways through the composite structure, each opposite faces, one of the edges of two adj acent elements being disposed at each side of one of said tenons whereby said two adjacent elements .are spaced apart by the widthof said tenons to form passage-ways between said elements parallel to one of said first-named groups of passageways, each passage-way in said elements registering with acorresponding passage-way in the next adjoining element, and each of said passage-ways formed between said elements registering with the corresponding passage-way formed between the next adjoining elements.

6. A regenerator comprising a plurality of interlocking like elements to form two groups of continuous passage-ways at right angles, said elements being spaced apart in rows, alternate rows of said elements being displaced laterally so that eachelement is centered with the spaces between elements of the next adjoining rows to form a passage-way, each of said elements being provided with a tenon to project into said spaces, one of said groups of passage-ways registering in vertical rows, and the other of said groups of passage-ways registering in horizontal rows, the passage-ways formed betweensaid elements being parallel to said horizontal rows or passage-ways.

7 A regenerator comprising a plurallty of interlocking like elements, each element being symmetrical about each central planethereof, two groups of passage-ways through each element at right angles, tenons upon two opposite sides of. and in a central plane of each element, said elements superimposed rows, alternate rows being displaced so that the tenons thereof project into the spaces of the next adjoining rows, whereby each passage-way in each of said elements registers with a corresponding passage-way form two groups of continuous passage-ways at right angles through the composite structure.

In testimony whereof I affix my signature.
