tml
a; slideelevatin of thd heating lsectional view on the line 3-3 l with the lresistance 4units removed e r containers.- y
ist sectienel View from' lgghe-ati'g chamber comprises'a tubular ne y,reglv-p'paiera-bly a-metal cyhnder pro- [v1 ed lwit a -cap 2 having screw threaded engagement therewith, the latter having a screw threaded ripening@` ada ted to be coninected to a pipe. The cylin er has secured to the llower end thereof a ri 4 made preferably, of cast metal and.V aving screw secured thereto an additional ring 6 e readily removed n asectiona1'e1evation of a four on the line 4-4 i threaded engagement therewith; said ring having a screw threaded opening 5 for vthe attachment of another ipe. The rin- "4 has aving both vertical and ,horizontal anges as shown, said ring serving to secure between itself and the rmg 4 a metal disk 7 and a washer or gasket 8 preferably of rubber. These parts are held in p'osltion b the screws 9, which pass upward throug the horizontal flange of the-ring 6 into the ring ,4, whereby the metallic disk is firmly clamped in place and a water tight connectlon is secured. A metallic casin '10 is scf e ring 6,
' 'ro l,
cured within the lower part of t by means of suitable screws 11.
The disk 7, which is made preferably of copper, has a plurality ofopenings therein, four in number in the present instance 12. f course, a 4greater or less number of ,containers may be employed, depending on `throu h which pass sheet metal containers,
my (zo-pending a plicationp hereinbefore mentioned, in whic a l'slotted metalfribbon is employed. .The rojecting ends 13 of said ribbon are clampe'v together below theinetal"4 disk Vas shown in V2, the individual ends beingseparated from each other' by mica s acers 14. 'A screw threaded stud 15 asses tiirugh suitable openingsl in the metalginsulation, nuts 16 being employed to clamp the parts together. Suitable U shaped jumpers 17 are also employed, whereby the circuit ma be completed "to the individual.; units, and' the circuityconnections may bev readily varied if desired.` Suitable terminal 'finembers 18` arealso clamped: between the nuts 16 and are so disposed as to' give the desired' circuit connections, Screws l194 are einployed to clampthe circuitlconductorsyto theterminal members 18, said circuit "com ductors enteringthrough the opening of 4the casing 10.
as L
e terminal members 18;;'are -Ymru Y referably spread out radially 'as shown in ig. 1, to facilitate the, securing. of tbecoe" passes u is' heate ductors beneath the heads of the terminal screws 19.
It will be seen that the containers 12 are supported by the metal diaphragm, .and hence may be readily assembled within the heating chamber and as readily removed. They ma however, be reinforced at their upper en s by means of a suitable cross .strip 20, the latter being secured tov the inner walls of the tube 1. A faucet or lstop cock 21 is mounted in a suitable opening in the ring 4, whereby the heated fluidv may be drawn oi if desired. V
In operation, the heating chamber is ordinarily in communication with apiping system through which the fluid flows, the fluid` entering through the opening 5 and leaving through the opening 3 whereby it wardly around'the containers and by the heating units, thereby insuring circulation in the direction indicated. The piping system may be connected with a suitablereservoir, wherebythe heater may be used to heat a body of liquid much in excess of lthe capacity of the heating Chambon Inasmuch as the heating units are inserted into their containers from below the supporting ldisk .7, itis apparent thatany one 'o 'r all of said units may be removed and replaced at will by 4sim ly disconnecting the various terminal menagere, but without disturb'ing the water tight connection between the 'containers and their supporting disk. Furthermore, the heating 4capacity ofthe device may be varied by removing the diskl or head and substituting in its place one hav-v ing a greater or less number 'of containers and heating units. The circuit terminals being arranged within the casing -10 are protected thereby, but access thereto may be ad readily by removing said casing; InaSmuc'h as the device is supported y the with which it is connectedLand not ysald casing, which constitutes the 1owermostpart` thereof, the removal ...of said casing may be conveniently accomplished.
' It `1s to'be understood that I do not desire to 'limit myself tol the details of construction described and illustrated, exceptwhere limitations are imposed in the appended claims. y
Having thus described my invention what I 'claim as new and desire t0 Secure by Let 1 ters Patent of the United States is:
