Ta all 'whom z't may concern,"

Be it known that I, EDWARD II. J. Dir-LON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Storage Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such .as .will l@ enable others skilled in the art to lwhich it appertains to make and use the same.

This invention relates to storage heaters of lthekin'd employed for supplying hot water or other liquid in quantity, and particularly storage heaters of this kind in which the heat is vindirectly supplied, as by the condensation of steam in tubes projected into the shell forming the storage tank for the liquid to be heated. 20. The principal object of the invention is to provide a heater of this character in which the heating tubes formingthe :so-called tube bundle may be readily withdrawn from the storage shell for cleaning or repair by one 5 or two men notwithstanding the weight and bulk of the tube bundle.

In storage heaters of comparatively large capacity, particularly where exhaust-steam is used as the heating medium and there is 3 0 consequently but a small difference between the steam and the temperature to which the water is to be raised, the necessary tube surface is large, and if the water to be heated is of a scale-forming character the tubes must be cleaned at frequent intervals to obtain etlicient operation. In such heaters as now construetedit is a diiicult task to remove the heavy bulky tube bundle without gasket employed between the tube supporting sheet'and wall of the shell. ',According to my invention, I support the tube bundle in such a manner that it may be withdrawn to a sufficient extent without lifting or suspending the weight of the tube bundle for the tubes to be readily cleaned, and may then be guided in its return movement' in such a manner as to position the tube supporting sheet accurately on its seat without damage 0 to the latter.l

In the accom anying drawings I have illustrated a preflrred embodiment of the invention, and a modification adapted forl different styles of heaters.

1920. Serial No. 390,237.

Referring to the drawings; `Fig.v 1 is aside view of a storage heater, the tank being broken away, the tube bundle being sectioned;

Fig. 2 isa view showing the tube bundle drawn out of the tank;

Fig. 3 is anend View; Fig. 4C is a view similar to Fig. 1 showing a modification; and- Y Fig. 5 is a view of line 5 5 of Fig. 4. The tank for the heating and storage of @5 the hot water is indicated at 1, and is preferably arranged in a horizontal position. One end of the -tank is provided with an opening 2 through which the tube bundle is adapted to move. rIhis opening is reinforced by an 7@ annular ring 3. The tube bundle, indicated at 4, comprises a number-of horizontal tubes supported at their inner ends by the plate 5 and atAtheir-outer ends by the plate 6. A dome-shaped cap 7 is mount/ed on the plate 5, the space within the cap being in communication with the ends of the several tubes of the tube bundle. 'Ihe cap is pro-v vided'with a supporting arm 8 which is inclined downwardly and outwardly as shown. f3@ The arm is provided with a roller 9 that moves on the track 10, positioned inside the tank and longitudinally thereof. Associated with the supporting plate 6 isa cap plate 11, these two plates being shaped as shown in Fig. 1 to accommodate themselves to the angle of the end of the heater. Plates 6 and V11 are provided with recesses which register toform the steam inlet chamber 12 to which steam is led by the inlet pipe 13.

At the outer end of the tube bundle are two supporting arms 14 which are Screw 15 on the plate 1l and'with adjusting nuts 16, so thatthe outer end plates of the tube L bundle may be adjusted for accurate seating in the end of the storage tank. The arms 14 are provided with rollers 17 which move on as desired. v

'I-he heating medium which may conveniently be exhaust steam, enters-through the 105 pi e 13, is distributed through the tubes of the tu e bundle and passes into the space withinl the cap 7, thus heating the water within the e densed steam esca with inlet and outlet chambers 24 and 25 out ot the tank, for

sag. Moreover, when the bundle is all thel way in the tank in normal position the inner 1 -end'ot the bundle will not sag,

- all parts ot .With the. supporting arms formed by cooperation of the outer end plates 26 and 27. "lfhe inner end ot the tube bundle is supported by a plate 28, which in turn is supported by a downwardly and outwardly inclined arm 29 provided with a roller 30 movable on the track l0.

lFrom the constructions that have been described it will be apparent that the tube bundle may be moved well out of the tank so as to be accessible for scaling and repairs, both ends of the tube-bundle being 'sup orted during the entire movement of the undle. Atny sagging of the inner end ofthe bundle is to be avoided, because it prevents accurate seating of the outer supporting plate and makes the in andout movement of the tank diiicult. By virtue ofthe tact that the inner end of the tube bundle is always supported, there is no tendency, when the bundle is half way out or all the way that end of the bundle to resulting 1n outer end plate. 8 and 29, as the case may be, inclined as shown, the tube bundle is projected well out of the tank so that itl are completely accessible, while at vthe same time the support Jfor the inner end is still restingon the track inside ot the tank.v

While ll have illustrated two supports for the accurate seating of the l the outer end ot' the bundle' and one support tor the-inner end, it, of course, should be understood that this arrangement might, be reversed, or that various other supporting vdevices for the endsot the tube bundle mi ht 'be used. llt shuold alsobeunderstood t at other parts of the apparatus are not limited to the precise structure shown, but may be embodied in other forms, as falling within the scope of the following claims. i

lltis also to be understood thatvwhile the apparatus has been described as` a water heater, it isnot limited to such use, but may obviously be employed tor other purposes, and theinvention is in no wise limited to the use of the apparatus for heating water.

l claim:

, l. ltn a water heater, the combination of a v tank, atubebundlemovable into and vout et meneer the tank, means located within the tank to support the inner end of the tube' bundle during its movement, said means comprising a supporting element associated with said bundle and contacting with thestationary portion of the tank at a point materially beyond the end of said bundle, and means to vsupport the outer end of the bundle.

A 2. ll'n a water heater, the combination of a tank, a horizontal tube bundle movable into and out of the tank, a track within the tank,

'dle being movable on the outer track.

3. lin a water heater, the combination of a tank, a horizontal tube bundle movable into and out of the tank, means to support the outer-end of the bundle during its movement, an inclined supporting arm to support the inner end of the tube bundle, and a track located within the tank,- on which the inclined supporting arm moves.

i 4. lin a water heater, the combination of a tank, a horizontal tube bundle movable into and out'ot the tank, means within the tank to support the inner end of the tube bundle, and means to support the outer end of the tube bundle, said means comprising threaded supporting members and nuts on said members, whereby the height of the outer end of 'said tube bundle may be changed by alter- `ing the position of said nuts.

the combination of a movable into and 5. ln a water heater, tank, va heating element out of thetank, and means within the tank4 to support Ithe inner end of said heating ele- -ment, said means comprising a supporting ment, said means comprising a supporting bracket projecting inwardly beyond the inner end of the heating element whereby the entire heating element may be AWithdrawn from thel tank without withdrawing the support from the tank, a roller carried by said bracket adapted to `roll along the bottorn of said tank and tached to the ment and adapted to support the outer end ont the heating element as the heating ele-v ment is withdrawn. from the tank.
