' Appiicaiioa ined Aprile, 1915. serial No. 19,968.

To all 'wlioii iti/my concern Be it known thatl, Lans Oriol* HEDBLOM, al subject of Gustavus V, King of Sweden, and a resident of New Brunswickyiii the county oit Middlesex 'and State of New J ersey,"- have invented certain new and useful improvements in Hot-Water Heaters and of which the following is a speciii'cation.

My invention is an improvement in water heaters and steanrgenerators, and especially in that class which relates to fast water heaters and consists in certain novel combinations of parts as will oe hereinafter described and claimed. ,y

One advantage of this invention is topresent a very largeheating surface to a small quantity of water.

Another advantage isjto provide a water heater which becomes adapted to steamy generation by valve readjustment. f

` Another advantage ris to provideconnections between separate water )acketsor con- `tainers without pipes.

`nother advantage is to provide a valve which shuts oli all water when a certain nut,

is removed to permit access to the .main

filter of the apparatus.

Another'advantage is to provide an appadisasseniljiled and inspected. p Another advantage is to provide an appa.-V ratus of this class that canlie greatly aided in resisting pressure by utilizing securingy bolts to 'hold the apparatus together.

y'Further possibilities and advantages will become apparent as thespeciiication proceeds. f

lVith fthe raforesaid advantages `in view,

`the invention comprises the improvements and combinations of parts hereinafter described in'their embodiment, pointed out in the claims and illustrated in the accompany-y central crosssection of the. apparatus in yits,

entirety. Fig. 3 is a topview of cylinders A or D of Fig. 2 with the super-imposedy flue-.block in Vhorizontal cross section. Fig. 4 isla top view ofcylindersB or E of F10'.

il is a section of Fig. le on line A and B.

l2 is a bottom view of Fig. 9. Fig. 13 is a bottom view of modified securing means. Fig. l-ilf is a sectional view of Fig. 13.

rihe apparatus is preferably constructed of sheet copper, or any suitable metal, and

'mainly comprises water containers'or water heater units. Each such unit is actually a liquid heating cell which ymay have any form allowing for the presenceof a central baille' wall, the purpose of which latteris to partially obstruct the incomingv liquid and to force the latter to iiow to'tlietlremotest portion of the unit before it can turn to the port of exit. This causes the liquidto contact with one direct heating wall throughout its course, as it travels rst on one side of thehatfie walls and returns through the same distance on the other side.

Referring tothe drawings., the same letters' and numerals referto like parts, ror

parts serving the same purpose throughout all the accompanying drawings'.

In Fig. l I have the main principles ofv kmy invention. The heavy dotted lines 'indicate the interior construction. llhe ar rows indicate the general direction taken loy the hot gases rand the definite course takenr hy the water through the apparatus.

ln Fig. 2 of the drawings, E, C, DQE and F serve the saine purposes as in Fig. l, `and are the annular walls lof the water heater units or cells. Also c, l), c', d, c and f are the horizontal tops of theheater units.

The annular wall A is secured tothe y,

round disk a by spinning in theiupper edge of A as at K, and lorazing or fastening a under this edge loy any means knownto the trade. in the same manner are the disks 5 c. d, c and ,f secured to their respective y walls. Disks c and f are similar 'to disks a and el, though of different diameters. yDisks ande, however, `are really-'parts'kof the partition or baffle walls within the heater units and are slightly different fromthe foregoing disks. 'lllie otherwise semilcirf @5. jet Z.

cular flue to the right is here reduced and circular, counter-sunk and provided with a lid as at and y. Y

Between disks a. and is iitted a Ilue block X here shown in vertical cross section, but Otherwise shown in horizontal cross section in F ig. Li, where the semi-circular flue tothe left is notedby Fig. 7. Returning to Fig. 2, the same flue is occupied by but not noted by letter X, the flue to the eXtreme right by 71, andthe central circular flue accommodates vertical valve j). n flue block X openings lead from valve 79 and also from chambers r into chamber ZJ through aperture r. This same flue block is shown in horizontal cross section in F ig. 3.V Returning to F ig. 2, the blocks X', X, X" and kXW are exactly alike. The lowest flue block T has accommodations to the extreme right for receiving the end of pipe 9, and in the center for seating the lower end of valve y).

Surmounting the apparatus is iiue block U. To the right it receives the end of valve t. To the extreme left is the exhaust vent ll, terminating in oblique position. in the center of the same iiue block, a collar or nut is fitted to accommodate the stem of valve y). A little to the right of the latter valve is the externally threaded nut N, tapered at its lower end and projecting down into chamber 72. iln'chamber g is placed valve N, which engages the lower tapered end of nut N. Valve N is by virtue of its arrangement forced toward the right Vby screwing down nut N, thus allowing more water to pass valve N. If nut N is removed, the helical spring on the stem of valve N will close the latter. Directly beneath nur. N is a strainer and mesh which are accessible by removing the nut, the flow of water then automatically ceasing as has been stated.

The flue block y has no horizontal vents from the central or yeXtreme right hand fines, but the flue 7 to the left communicates at 7 Y through the external wall with the space (Z in kwhich, the block is situated. Pipe 9 extends downward and connects with pipe z by means of an elbow on the level of ring R. Pipe z' runs obliquely down through gasv burner O to valve J. Valve Zt controls pipe Zt, the latter connecting below with an automatic double intalre valve c in casting c. Pipe It connects valve e with external water source. rThe combustible gas is supplied to chamber Z in n from valve Z.

Part of the gas is diverted upward into jet Z Y which is alwaysburning.

` In operation, the valves Zz and J are opened, lpermitting a flow of water through the` entire apparatus. The water from Zt will force open and retain valve n against lts spring, and cause gas to pass valve c up into burner O where it will be ignited by Noting the course of the water from valve n', it iows through pipe ZL to valve Zt, and passing valve N enters chamber p. Thence the water proceeds through lter M in disk a into chamberr where it finds lid ai normallyy closed. From chamber r the water fiows through vvent z' into space b and down between A and B to G. Between G and Z9, the water doubles upon itself and proceeds. upward in space 2 until it reaches disk b, where the water converges toward the cen trai flue block in space c, and, finding inlet s, arrives in chamber a. From chamber a the water dives down to chamber t whence it takes its course in space e', down space 3, to annular ring 7c and up through space l to space f. Thence the water again converges toward the center, and finding a vent u, enters chamber u. If there were a whole series of such water heater units the water would proceed through the succeeding units and make the same kind of journey through each as has just been described concerning two suoli units. ln this case, however, the water now leaves chamber u, flows down through pipe 9 and out through valve J to external use. j

lWere the apparatus to be used as a steam generator, the steam would rise simultane ously all vertical spaces in the heater and seelr a general outlet. In order to meet these new conditions, the valve p is provided. Being turned half a revolution to the right, this valve is capable of connecting, vby means of slot n, 'the chambers u and t through vents n and a. Also chambers a and r. will be connected by slot m through apertures m and m. This will afford the steam the opportunity to rise to theV uppermost chambers and obviate immediate danger of explosion. However, in Y order tofurther vfacilitate a more rapid and free exchange vention from within, small lids w and y yare l provided, being temporary auxiliaries of the central valve in 'case the latter should be forgotten or used tardily.

lf it be supposed that steam is generated in spaces l, 2, 3 vand 4, it will rise to the horizontal spaces Zi', o', eand 7 and will rise fromr chamber w to t throuvh solt n c up through flue 7 to chamber a where more steam joins 1t from space c. Thence the steam passes'upward through slot m to chamber/1 and up to p where the entire output or" the apparatus gathers. j

It isto be expected that steam will be generated in spaces 3 andk morerapidly than in spaces land 2, due to greater exposure to -r heat'.k The water level `would thus fall' below thatcf spaces liand 2,2but thisfis entirely counteracted by valveigwhich, by

virtue of slot @,permitsvthe water/,fromm spaces 1 and 2to iowintospaces 3 yand. 4f, causing a compensating,rise` in these latten The heated gases fromburner Opass up- `ward` `in chamber 6 where they find flueB,

thencepassingup to Ventv 7 are augmented by` more gases from spaceua From this point the gases'pass upward toven't y11 and then out. i f i i lt is, ofcourse, understood that theuse of gas as fuel is optional, as welll as auto-` i matic valves o and `N.
