HEATER FOR WATER 0R OTHER FLUIDS.

Specification of Letters Patent.

Patented Oct. 1%, 1916.

To all whom it may concern:

Be it known that I, WVILLIAM A. TRAVER, a citizen of the United States, residing at Providence, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Heaters "for ater or other Fluids, of which the following is-a specification.

Myinvention is an improved heater for use with dyeing-keirs, kettles, vats or similar apparatus employed in various arts.

My improved heater is intended for use particularly in heating dye-liquor, mordanting-fluid or washing-water during the process of dyeing, bleaching, scouring, washing or otherwise treating textile materials with a fluid bath.

The object of my invention is to simplify. the construction and improve the arrangement of the apparatus to increase its efficiency, and particularly to provide for easier access to its interior and a more convenient method of removing and reassembling its parts for the purpose of cleaning, repair or replacement.

The method and means for carrying out these improvements are fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate like parts.

In the drawings :Figure 1 is a sectional elevation of my improved heater; and Fig.

2, a plan view of the same showing its eX- terior shell in section to illustrate the parts inclosed therein.

Referring first to Fig. 1, my improved heater is preferably constructed in the form of a cylindrical tank or container A comprising the convex end heads B and C and the outer inclosing drum or shell S. The head 13 forms the base of the tank and is provided with a flanged rim 7) to which is bolted the rim (Z of a transverse, circular plate or diaphragm D. At the center of a convex base 13 is an opening Z) surrounded by an interiorly-threaded flange or collar F held in place by the bolts f. Screwed into the flange F is a pipe Ewhich is adapted to be connected with the boiler or other source of the steam which acts as the heating agent and is admitted into the bottom of the heater beneath the diaphragm D. Screwed into the diaphragm D and extending vertically upward therefrom are a plurality oi relatively small pipes at, 03, through which the steam passes to communicate its heat to'the fluid in the main compartment of the tank A. As many steam-pipes d are provided as can be conveniently inclosed within the shell S in spaced apart relation, being either arranged in concentric circles or in the form of a geometric figure as shown in the plan view, Fig. 2. 1 Overlying the top of the diaphragm D and spaced a slight'distance above it is a circular plate Gwhich forms a false-bottom for the tank A. The'false-bottom G is constructed in the form of an inverted cup havinga depressed, annular rim or flange g which rests on the rim (Z of the diaphragm D overlying the flanged rim 6 of the base B.

Qverlying the flange g is a circular collar orring H having its mm It formed with an upstanding web or flange h to the inside of which is riveted the outer, cylindrical shell S. Theshell S also has a flanged ring J surrounding its top and riveted thereto to provide a means for attaching the head or cover C to the tank. Preferablythe cover C is of the same form as the base B and is secured in place by means of the bolts .0 reaching through holes in its flange and in the ring J. A pipe K is screwed into a collar 7a which is bolted to the top of the cover C surrounding its central opening 0, and serves as the outlet for the tank to provide for the egress of the heated water or other fluid therefrom. The pipe K leads to the keir or other apparatus in which the heated liquid is employed during the dyeing or other process. The ingress for the fluid into the tank is preferably near its base and, as

shown in Fig. 1, consists of a pipe L screwed into a collar Z which is riveted to the side of the shell S.

Inclosing the steam-pipes d are a plurality of larger pipes P, screwed into the false-bottom G. The pipes P extend upwardly some distance above the tops of the steam-pipes cl and are closed at their ends by the caps 32. It will be'noted that a space is left between the outside of the steampipes d and the interior of the pipes P to allow the steam to circulate therein. their lower ends the pipes P open into the space between the diaphragm D- and the false-bottom G and to take care of the con- 'densation of the steam in this compartment 1 I;

of the tank a drip-pipe 0 leads therefrom down through the base B. The drip O is usually connected to a suitable drain leading to a catch-basin or sewer.

The particular and novel features of my invention which provide for the improvements hereinbefore referred to are first: the arrangement of the means for bolting the several parts of the base of the heater together to provide for removing the outer shell without disturbing the relation of the diaphragm D and false-bottom G: and secondly, the arrangement of the standpipes of the heater whereby any one of them may be taken out by itself without necessitating the removal of the adjacent pipes. Referring to Figs. 1 and 2, it will be noted that the base B, diaphragm D, false-bottom G and ring H are all held together by the bolts N inserted from the bottom through suitable holes in their rims 5, (Z, 9, [1,. Applied to the upper ends of the bolts N are nuts a which are screwed down against the rim it of the ring H to bind the several parts together, and usually packing-rings or gaskets, not here shown, are placed between the joints to render them fluid-tight.

Besides the bolts N I also provide four bolts M, shown by dotted lines in Fig. 2, and

at the right in Fig. 1, which reach up through alining holes in the flange b of the base B and rim (5 of the diaphragm D with their ends screwed into the rim 9 of the false-bottom G. This provides that when the main holding bolts N are removed to allow for lifting off the shell S, the auxiliary bolts M will still hold the base B, diaphragm D and false-bottom G together without disturbing their relation. That is to say, the shell S and its holding-ring H may be removed from the base of the tank by simply unscrewing the nuts a without disturbing the arrangement of the other parts of the base or loosening their joints. Heretofore, in all apparatus of this type, it has been necessary to disconnect the lower head or base, the diaphragm and the false-bottom in re- 'moving the outer shell of the tank and then to reconnect all the parts when the shell is again replaced. In other words, the several joints must be disconnected and their gaskets disturbed so that refitting and re packing of the joints is necessary when the parts are assembled again.

It frequently happens with heaters employed for the purposes herein enumerated that the pipes become rusted, corroded or clogged and require cleaning or replacement. \Vhen this becomes-necessary it is an easy matter with my improved arrangement to simply unfasten and lift off the shell S with its attached cover Cwithout disturbing or disarranging the other parts of its base. In addition to the present improved arrange ment for removing the shell S I have also provided a much simpler and more convenient method of individually disconnecting the standpipes of the heater. Referring to Fig. 1, it will be noted that the pipes P of the cluster or series in the shell S are of graduated lengths. Referring also to Fig. 2, the outer ring or set of pipes P are the shortest, with the next inner set P slightly longer, the next set P still longer, and finally the center pipe P longest of all. This provides that the several sets of pipes will project one a slight distance above another toward the center of the cluster. The purpose of this arrangement which constitutes an important feature of the invention is to provide for reaching across the tops of the outer pipes with a wrench so as to allow for attaching it to any one of the in ner pipes in the series. That is to say, if

it is required to remove the central pipe P,

for instance, for cleaning or replacement a wrench W, shown in dotted lines in Fig. 1, can be applied to its upper projecting end without interference with the other pipes arranged around it. Likewise, any one of the series of pipes P may be grasped with a wrench above the pipes P and pipe P so that they can be turned in either direction, without interference, to unscrew them from the false-bottom G or to replace them in their sockets. It will be noted by reference to Fig. 1 that the small, inner steam-pipes (Z are also graduated in length proportionately to the inclosing pipes P so that their removal and replacement are accomplished in the same manner as above described. Through this arrangement any one pipe or set of pipes may be removed and replaced without displacing the several adiacent pipes surrounding it, whereas, in all heating-tanks as heretofore employed it has been necessary to start at the outside and remove all of the adjacent pipes before one or more of the central pipes could be reached with a wrench. This work entails considerable extra labor and consumes valuable time, whereas, with my present improvement, any individual pipe in the group may be selected and removed without disturbing its neighboring pipes. In this way a considerable saving of time and labor is effected during the cleaning or repairing of the heater and furthermore the whole arrangement is much easier to assemble during its manufacture.

In use my improved heater operates in a well-known manner as follows: Steam is admitted through the intake-pipe E and distributed through the diaphragm D to the several small standpipes (Z. From the upper, open ends of the pipes d it circulates down through the radiating pipes P and into the space between the false-bottom G'and diaphragm D, from which the condensation is carried off through the drip O, or, if preferred, a return pipe may be led back to the boiler.

The water or other fluid to be heated enters through the ingress-pipe L and, as generally provided, is forced through the heater and its connected keir or other apparatus by means of a circulating pump. As the fluid circulates betweenthe standpipes P the heat generated by the steam is radiated therefrom and, as the fluid becomes heated, a thermosiphon action is set up with the hottest fluid rising to the top of the tank A. In some cases this action is sufficient to maintain a constant circulation of the fluid through the tank, drawing it in from the intake L and forcing it out through the pipe K with the hottest portion alwaysfeeding first.'

Usually a water-gage is provided onthe top of the tank and a thermometer is em ployed to indicate the temperature of the heated fluid so that the supply of steam may be regulated as required. These devices, however, form no part of the present invention and therefore are not herein shown or described.

It will be understood that I do not herein claim broadly the general arrangement of the type of heater shown and described, but only the particular features of construction which make for the advantages above pointed out.

What I claim is 1. In a heater for water or other fluids, the combination with a closed tank having an inlet and outlet for the fluid to be heated and an intake for the steam, of a series of pipes grouped around the interior of the tank and communicating with the steam intake, said pipes being of graduated lengths arranged with the longest one in the center of the group and with the others stepped down in shorter lengths toward the outer walls of the tank.

2. In a heater for water or other fluids, the combination with a closed tank having an inlet and outlet for the fluid to be heated and an intake for the steam at one end of the tank, of a diaphragm extending across the tank adjacent the steam intake, and a group of steam-pipes of graduated lengths secured in openings in the diaphragm and arranged with the longest pipe in the center and with the others stepped down in shorter lengths toward the outer walls of the tank.

8. In a heater for water or other'fluids, the combination with a closed tank having an inlet and outlet for the fluid to be heated and a steam intake at one end of the tank, of a plurality of steam-pipes grouped in spaced relation around the interior of the tank and communicating with the steam intake, and a series of larger pipes inclosing the steam-pipes with a space between their walls for the circulation of the steam therethrough, said steam-pipes and their inclosing pipes being of graduated lengths with the shortest pipes on the outside of the group and the inner ones projecting beyond the ends thereof in stepped relation toward the center of the group.

4. In a heater for water or other fluids, the combination with a closed tank comprising a cylindrical shell having end heads connected thereto with an inlet and outlet for the fluid to be heated, of a diaphragm extending across the tank at its base, a falsebottom overlying the diaphragm in spaced relation thereabove, a steam intake communicating with the compartment below the diaphragm, a series of vertical steam-pipes extending through the false-bottom and se cured in openings in the diaphragm in comsmunication with the steam compartment,

and a plurality of larger standpipes secured in openings in the false-bottom inclosing the steam-pipes with their upper ends closed above the open ends of the steam-pipes, said steam-pipes and standpipes being of graduated lengths grouped in series with the shortest pipes on the outside of the group and the inner pipes gradually stepped upwardly toward the center to provide for grasping the pipes individually with a wrench one above the others.

5. An improved heater for water or other fluids comprising a tank having a convex base formed with a flanged rim, a diaphragm arranged with its rim overlying the flange of the base, a false-bottom having a depressed rim overlying the rim of the diaphragm, a flanged ring overlying the rim of the false-bottom, a cylindrical shell riveted to the flange of the ring, a cover secured to the opposite end of the shell, a plurality of bolts reaching through the several overlying rims of the base, diaphragm,

false-bottom and ring to draw the parts together to seal their joints, and a series of shorter bolts extending through the rims of the base and diaphragm and screwed into the rim of the false-bottom to hold these parts together while allowing the removal of the shell and its holding ring.

6. An improved heater for water or other fluids comprising a tank having a convex base formed with a flanged rim and provided with a steam intake, a diaphragm arranged with its rim overlying the rim of the base, a series of vertical steam-pipes secured in openings in the diaphragm, a false-bottom spaced above the diaphragm and formed with a depressed rim overlying the rim of the diaphragm, a plurality of standpipes secured in openings in the false-bottom with their walls inclosing the steampipes, a ring overlying the rim of the falsebottom and provided with an upstanding flange, a cylindrical shell riveted to the flange of the ring, a similar ring riveted to the top of the shell, a cover secured to said last named ring, a plurality of bolts extending through the rims of the base, diaphragm, false-bottom and lower ring to secure the parts together with fluid-tight joints, and a series of auxiliary bolts extending through the rims of the base and diaphragm and screwed into the rim of the false-bottom to hold these parts together when the shell is removed by removing the main bolts extending through its holding ring.

7. An improved heater for water or other fluids comprising a tank having a convex base formed with a flanged rim and provided with an intake for the steam, a circular diaphragm arranged with its rim overlying the rim of the base, a series of vertical steam-pipes screwed into openings in the diaphragm, a false-bottom spaced above the diaphragm and formed with a depressed flange overlying its rim, a plurality of standpipes screwed into openings in the false-bottom to inclose the steampipes extending therethrough and grouped in series with the shortest pipes on the outside and increasing in length toward the center of the group, a ring seated against the rim of the false bottom, a cylindrical shell fastened to the ring and extending upwardly therefrom to inclose the group of standpipes, a cover secured to the top of the shell, a series of bolts extending through the rims of the base, diaphragm, false-bottom and shellring to draw the parts together, and a series ofrshorter bolts reaching through the base, diaphragm and false-bottom to hold these parts together when the shell is removed by releasing the main bolts extending through its ring.
