(ill. hill-55) 4 Claims.

This invention relates to heat exchangers.

A principal object of this invention is the production of a device or" the type specified which will be simple and inexpensive to construct, efiicient in operation, and afford unusual facilities for disassembling.

Other objects and advantages will appear as the description of the particular physical em-= hodiments selected to illustrate the invention progresses and the novel features will he particulerly pointed out in the appended claims.

In describing the invention in detail and the particular physical embodiments selected to illustrate the invention, reference will be had to the accompanying drawings and the several views thereon. in which like characters oi reference designate lflze parts throughout the several views, and in which:

Figure l. is a side elevational view of a heat exchanger embodying the invention, some parts being broken away to more clearly show the construction; Fig. 2 is a fragmentary top plan View of the device as shown by Fig. 1; Fig. 3 is a view of the end of the device shown :by Fig. l as viewed from the right hand end thereof; Fig. 4 is a fragmentary view of the device of Fig. l drawn to larger scale; Fig. 5 is a cross-sectional view on the plane indicated by the line V-V of Fig. 4, viewed in the direction of the arrows at the ends or the line; Fig. 6 is a longitudinal sectional view on the plane indicated by the line VI-VI of Fig. 4, viewed in the direction of the arrows at the ends of the line; Fig. 7 is a view corresponding to Fig. 4 exhibiting a modified form of the invention; Fig. 8 is a cross-sectional view on the plane indicated by the line Vm-VIE of Fig. 7, viewed in the direction or the arrows at the ends of the line.

The device, in geneeal, is of the ordinary heat exchanger form. in that it comprises a hollow cylindrical metal body designated generally by 1, provided with; a bundle 2. serving the runstion or the ordinary tube bundle; an inlet iii to one header space giving access to the interior of x the tunes or the bundle an an outlet o iroln an other header space giving access to the interior lid head-er s separated d an outlet for fluid surrounding the outside of the tubes or the hundle 22. the left hand end or the bundle 2, as viewed 1 is arranged in a conventional manner or in accordance with the invention similarly to hand end, insofar applicable,

in the construction shown in Figs. 3.. to d in It is, or course, understood elusive, the shell is interrupted at l entirely around the circumference and a gasket ring 5 extending circumferentially, around the shell is attached thereto, as by welding The cylindrical body l is continued beyond i by the shell extension ill which is also welded to the gasket ring has at i i.

The extension ill is formed with two cut-away portions, i2 and it, at opposite diametrical points. The spaces formed by these cut-away portions extend iroin the extreme right hand outer end of the extension 5%, as viewed in Fig. i, to the pointi l and are of a width suflicient to pass the nozzle outlet 3, at its diameter 55, longitudinally of the shell.

The nozzle outlet 3 and nozzle outlet c are welded to channel it as at it and it. The chan- .81 is in the general form of an annulus substantially fitting the inner surface of the extension ill, and is attached preferably Joy welding at it and 20 to head 23.

After extension it is attached, as'at Mend cut outs i2 andiii are removed, the channel to with attached nozzle outlet 3 and nozzle outlet 3! is slipped into place longitudinally of the cylinder l and then the portionsv i2 and it may be replaced, if desired The extension AG has through orifices, as 22, formed at spaced intervals around it.

A retaining ring 23 is positioned in the end oi extension l6 and is formed with orifices 2c corresponding to orifices 22.

.At the time'oi making the complete assemblg', the bundle z is first pushed into the cylinder l, with the tube head it bearing against an annular gasket 26 placed, against gasket ring d. A gasket M is then placed on the other side or the head 25. Then nozzle channel it is put into place. After ring 23 is put in place, hey locks to are fitted into the

orinces

22 and 2% with the shoulders 2e and to resting against the inside suri'ace of the retaining ring and the outside surrace oi the extension ill, respectively.

In order to hind all parts together fluid tight. the keys 532 e placed position with'tne lnn== against retaining ring threaded through orince :rneaded threaded screw has an iin- 'hich passes freely through i in the key lock are all in the positi the iaclt. screws lug ogainst the ch the channel l5 inwardly the tube head inwardly against gasket 26 and gasket ring 8 making all parts fiuid tight.

When removing the head, the jack screws 34 are backed out sufficiently to have their inner ends clear the key locks 28, whereupon the keys may be removed and then the key locks may be removed, thus allowing the retaining ring 23, the nozzle channel 16 and the tube head and bundle 2 to be removed.

The left hand end of the cylindrical member I may be arranged in the ordinaryor usual manher and may have the usual head afiixed therein in any or usual manner. It may also be attached, if desired, by a construction similar to the construction of head 2| insofar as the keys, key lock and jack screws are applicable;

In Figs. 6, 7 and 8, a modified construction is shown. In this construction the head 31 is separate from the channel 38 which carries the nozzle as 39.

In the modified construction, orifices, as 40, corresponding to orifice 22 of Fig. 1, are formed in the extension H, but the key and key lock is made in a single piece. The key is designated 42 and has a tang extending through the orifices as 40, and corresponding ring orifices 43. Each of the keys has an extending arm provided with a. groove 45. The grooves of the keys receive a jack screw retaining ring 46, pierced at intervals, as at 41, to receive a jack screw. The jack screws, as 48, are received in the through against gasket 21 and threaded bore 49 of the key and pass through an unthreaded bore 41 of the retaining ring 46.

In the modified form the channel 38 is separate from the channel head 31 and gaskets are placed at 50, 5| and 52.

Although we have particularly described one particular physical embodiment of our idea of means and a modified form thereof, nevertheless, we desire to have it understood that the forms selected are merely illustrative and do not exhaust the possible physical embodiments of the idea of mean underlying our invention.

What we claim as new and desire to secure by Letters Patent oi the United States, is:

1. A heat exchanger, including, in combination: a hollow cylinder, formed with a plurality of spaced orifices through its wall; a head for the cylinder; an abutment within the hollow cylinder for restraining the inward movement of the head and means for forcing the head inwardly including keys, each having one end projecting into an orifice and the other end positioned over the head, each key having a through threaded orifice; a threaded jack screw passing through each key and bearing on the head whereby the head is forced inwardly; and key locks, one associated with each key and between the key and the head and having one end pro- Jecting into an orifice and the other end over the head, each key lock formed with a lip lying along the outside of the cylinder and with a through orifice receiving a jack screw and a retaining ring provided with through orifices corresponding to the orifices in the cylinder and positioned inside the cylinder and receiving each of the keys and key locks.
