To all whom t .may concern.'

Be it known'tha-t I, HANS J. ZIMMERMANN,

a citizen of Germany, and a resident of the city of Philadelphia, in the county of Philadelphia, State of Pennsylvania, United States of America, have invented an Imrovement in Heat-Exchange Apparatus, of which the following is a specification.

My invention relates to pipe apparatus, particularly tothe means for supporting and holding the opposite ends of a cluster of pipes, which opposite ends open into chambers at the opposite ends of the casing withinv which the pipes are situated.

The opposite ends of thesaid. pipes are secured in diSk--like plates and the principal objectof the invention is to provide a new and novel means for securing these plates in position at the opposite ends of the said cas'- lng. L y v In theconstruction as' shown one of the disk-like plates Virs-"movable or adjustable while-the other is stationary, and one of the objects of the inventionis `to provide a' new and .novel construction of means for securing thev Said plates in position of such character that 'the packing means'employed for rendering the same steam or air tight are interchangeable; that is to say, may be used or employed in connectionA either with oneplate or. the other, as may be desired.

A further object of the invention is touprovide novel means forindicatingwhether or not the packing associated with themov.- able or adjustable plate ha's becomel'oose so that leakage is takmg place. I Other objects and advantages of the inven-` tion will be pointed Yout. in the detailed deik j saldopenings, the op osite ends of which are scription of the invention which follows or will be apparent therefrom. j

ln order that the invention may be readily understood and its practical advantages fully appreciated, reference may be had to the accompanying drawing in which one form of embodiment thereof is illustrated. However, it will be understood that the inventionis susceptible of embodiment in other forms of construction than that shown and that changes in the details of construction may be made within the scope of the claims without de arting from the invention.

In t e drawing: Fig. l1 iS' a Central vertical sectional view \meanS associated with the movable disk- like bolts 24 and 25.

pf a Ipipe apparatus embodying my invenion; Fig 2`is an enlarged fragmentary sectlonal view showing more clearly the construction and arrangement of the packingplate; and Fig. 3 is a similar View showing the construction and arrangement of means forsec urlng the. stationary disk-like plate in position. f

I teferring to the drawing: l designates the caslng of avpipe -apparatus within which is situated a cluster of pipes 2. The opposite ends of the said pipes are secured in openlngs through end plates 3 and 4, each of which is provided with inwardly extending flanges 5 and 6. The opposite ends of theV casing 1 are closed by means of covers 7 and 8- which constitute chambers with which the opposite ends of the pipes 2 of the' cluster communicate. The inner end portionsof the walls. of the covers 7 and 8 rare thickened and mter1or`portions thereof are cut out to form angular grooves 9 and 10. The inner edges ofthe outer walls of these grooves are cut away, as indicated at 12 and 13, to form outwardly flaring Surfaces. The opposite endsn of thecasing 1 are likewise thlckened and the inner edges thereof Iare vcut away, as indicated` at 15 and 16, to form outwardly flaring surfaces similar to the surfaces 12 and 13.

- Adjacent its opposite ends the casing l is provided with laterally outwardly extending anges`20 and 21 each of which is provided 99 at- 'intervals .with screw-threaded openings 22and- 23. Bolts24 and 25 having screwthreaded inner ends are secured in the likewise screw-three ed and extend through openings 28 and 29 in laterally and outwardly extending lianges 3() and 31 adjacent the inner ends or edges of the covers 7 and 8. The said covers are adapted to 'be clamped and held against the oppositev ends of the casing or against packing means interposed between the. Said opposite ends and the opposing ends of the covers by means of nuts v 32 in engagement with the outer ends of the m6 Interposed between the inner edge or end of the cover 7 and the adjacent opposingk end of the casing 1 is .a ring 35 having` upon its inner side an annular groove 36. The said ring extends around the peripheral surface of the plate 3 and the presence of the annular groove therein provides an annular chamber between the said ring and the said plate 3 or its ange 5. The ring is provided With one or more holes or perforations 37 extending therethrough.

Instead o associating aseparate ring member with the opposite end plate 4 and its iange 6 I have provided a laterally and outwardly extending integral flange 40 which extends between the opposing ends of the casing 1 and the cover 8.

For the purpose of rendering the joints between the plates 3 and 4 and the easing 1 and covers 7 and 8 air or steam tight l have provided packing rings, as indicated at 41 and 42, of suitable elastic material such as rubber, which when in compressed condition or state, as shown in the drawing, are triangular in crosssection. As a matter ot' convenience, however, these packing rings may consist of members which are of any other desired cross section; After the parts have been placed in position with the paekin rings in place around the outer edges of t e plates 3 and 4 and their flanges, which rings are situated above and below the ring-shaped member 35 and the annular integral flange 4L), the covers are drawn tightly into position by tightening the nuts 32. The packing rings are compressed thereby into the triangular shape, as shown in Figs. 2 and 3.

It will be noted that by my construction I am enabled to employ packing rings of identical construction in connection with both plates 3 and 4 for the purpose of rendering the joints between the same and the casing and covers air and gas tight.

The presence of the hole or holes 37 which extend Athrough the ring-shaped member 35 permits steam or other fluid to escape in case either of the packing rings 41 should become loose and thus afford an indication to the operator or person in charge of the apparatus that the packing had become loose and needed tightening.

It will be seen that by my invention I have provided an eflicient, novel means for closing the joints between the j opposite ends of a casing, thecovers therefor and the end plates in which the opposite ends of a cluster of pipes are secured, which means is .not only economical as to cost of manufacture, but also may be placed and assembled readily in position Within the structure.

Having thus described my invention, what claim and desire tol secure by Letters Patent is:

1. A heat exchange apparatus comprising iin combination a casing, end plates situated adjacent the opposite ends of said casing which plates are provided with openings which extend therethrough, a plurality of pipes the opposite ends of which are secured in said openings, covers secured to the opposite ends of said casing and forming with the said plates chambers with which the opposite ends of the said pipes wznmunicate, a ring-shaped member situated between one end of the said casing and the opposin edge of a cover, which ring-shaped mem er loosely surrounds vone of thesaid end plates, and the said ringshaped member being provided with an annulax` internal groove and with openings leading'from, said groove to the atmosphere, and packing rings situated upon opposite sides of said ring-shaped member and clamped against the same and against the outer'edge of the said end plate by the opposing ends of the said casing and the said cover, substantially as described.

2. A heat exchange apparatus comprising in combination a casing, covers secured to the opposite ends of said casing, end plates situated intermediate the said covers and thc said casing, the said platesgeach-being ro'- vided with holes extending therethroug 1, a .plurality Iofv pipes, the opposite ends of which extend into said holes, a ring surrounding the outer edge of one of the said end plates, which plate is movable longitudinally of the said casing and with respect to the said ring which ring is situated between an adjacent end of the casing and the inner end of one of the said covers. the inner edges of the said casing and cover upon opposite sides of the said ring being beveled outwardly and packing rings situ: ated inthe spaces formed by such outward beveling, substantially as described.

In testimony that I claim the foregoing as my invention, I have hereunto signed my name 'this 23rd day of May, A. D., 1922.

HAN S J. ZIMMERMANN.
