BOILER.
Specification of Letters Patent.
Patented Jan. 14, 1919.
application led April 1, 1912. Serial No. 225,992.
To all whom t may concern:
Be it known that T, HENRY W. Zin/.turna MANN, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Boilers, of which the following is a specification.
My invention relates to clothes boilers, domestic cooking vessels and the like, and its object is to render such devices more reliable and eiiicient in their operation, as well as to provide for producing them economically.
My invention consists in the combination of parts and in the details of construction and arrangement of parts as will hereinafter be more fully described and claimed.
Tn the drawings:
Figure 1 is a sectional side elevation ofa device embodying my invention, the section being on a longitudinal vertical plane corresponding to the line 1-1 of Tfig. 2;
lig. 2 is a sectional plan view of the same;
Fig. 3 is a general perspective view of the device;
Fig. 4 is an enlarged partial longitudinal section corresponding to the section of Fig. 1 showing the lid in lowered position by olid lines and in raised position by dotted mes;
Fig. 5 is a sectional detail of the trough and the sheet removed from the center thereof; the section corresponding `to that of lig. 1; and
Fig. G is a similar section of the lower part of theldevice showing how the sheet of Fig. 5 is used to make the bottom.
F or the purpose of illustrating my invention, T have chosen a wash or clothes boiler as being a boiler or vessel to which my invention is especially applicable.
This boiler comprises the upright body l formed of one or more sheets of metal bent around with the ends joined after the wellknown manner of making the body of such a vessel. However, in accordance with one of the details of my invention, T prefer to make this body tapering from its top to its bottom, as shown in Fig. 3. The upper rim 2 of this body 1 is formed in a well-known manner preferably by forming it overa wire 3 contained therein according to the process comlmonly known in the art as 66wiring. short distance below this rim 2, the sheet of the body 1 is also preferably pressed outward into an outwardly extending bead 4:.
The trough 5 has a downwardly extending fiange 6 extending entirely around the outer side of the vessel body 1 immediately above the bead 4 and soldered or otherwise suitably secured to said body; and this trough flares or widens upwardly preferably with a crosssection of comp ound-curved or long-S formation terminating in an upper rim 7, which, like therim 2, is preferably ywired with the wire 8 inclosed therein. The flange 6 bearing down against the bead l all around is thus reinforced in its connection to the main body part 1 of the vessel. This liange is so proportioned relative to the space above the bead l and below the rim 2 that a considerable vertical extent of the wall of the part 1 is left exposed out in the trough above the bottom thereof and below said rim 2. Through the wall of the part 1 within the limits of this extent and with their bottoms substantially coincident with the bottom of the trough 5 are a plurality of holes 9, so that water will drain from the trough 5 into the interior of the main part l.
As T prefer to make this trough 5, a single continuous flat sheet of metal is formed into the trough 5, and its central flat part 5' is cut out, as shown in Fig. 5. This trough 5 thus remaining is fastened to the upper part of the main body 1 as described; and the part 5 owing to the tapering of the body 1 is large enough to be used for the bottom 10 (Fig. 6) which it becomes by forming a seam 11 between its edge parts and the lower edge of the sheet of the body 1.
The body may be provided with handles 12 in the usual manner.
The cover comprises the suitably formed main sheet 13 preferably having near its edge all around the depressed bead 14 and having its edge part turned downward and inward, forming a flange 15. The vertical shell 16 has its upper edge part formed radially outward all around into a flange 17 which is received between the edge part of the main cover sheet 13 and its inturned flange 15. The lower edge part 18 of this shell 16 is preferably formed up to strengthen the lower part of the shell in a well-known manner.
The cover thus made up thus has the radially outwardly extending ledge formed by the secured-together ianges 15 and 17 and the downwardly extending shell 16. rIhe latter is so proportioned that it fits snugly inside the upper part of the main body 1 of the vessel with the ledge coming down against the rim 2; whereupon the shell 16 projects below] and covers all of the openings 9 through which the interior of the vessel communicates with the interior of the trough 5 as before described. But when this lid is raised a short distance, its shell uncovers these openings 9.
Vith a device thus constructed, when water is boiled in the main body part 1, as, for instance, in boiling the clothes placed `therein with the water in the well-known manner, the steam from the boiling water will be conned in the vessel because the lid fits snugly in the upper part thereof and its shell 16 covers the openings 9. But this shell is not made to it so tight but that when the steam accumulates a moderate pressure, it will raise the lid and the steam will then escape through the openings 9 into the outer air. Water which is carried up with the steam when it thus escapes in the well-known action known as boiling over will be caught in the trough 5, and when the boilying over has subsided, the water thus caught will drain back into the main part of the vessel while the lid is falling to its original position. I prefer to extend the trough V5 a very material distance above the lid, as shown, so that even excessive amounts of .water boiling over will be caught by the trough and returned to the main part 1 of the vessel. Even if so much water escapes that it rises above the rim 2 and cover ledges thereover, this water will merely run onto the top of the lid from which it will drain back to the trough as the water drains from the trough into the main part 1 of the vessel.
It will be seen from the foregoing description that such a vessel constructed according to `my invention, whether it be for boiling clothes or for anykind of cooking vessel, may be effectively covered to retain the steam at moderate pressure and thereby obtain more effective results therefrom; but at the same time the boiler or kettle need not be closely watched in order that the heat may be decreased each time it threatens to boil over as is necessary with most boilers or cooking vessels. The boiling over conditionsare, of course, only at intervals with a properly regulated heating means for the boiler or kettle; and with .my improvement, such overflow as occurs each time is readily caught and returned to the vessel .without being wasted or wetting surrounding objects, as is the case -with a boiler or kettle allowed to repeatedly boil over without any means for catching the overflowing water. At the Sametime the steam is retained in the vessel at all times except during the short periods when the vessel is boiling over and the Water is thus not wasted as it is in most vessels by the continuous escape of steam around the cover which is purposely very loosely fitted in order to avoid as much as possible the boiling over periods. This is of great advantage in any kind of boiler, as, for instance, in boiling clothes on account of the economy of water and saving in labor of supplying the water to the boiler; and in cooking it is of additional advantage in permitting the substances and fiavors of the foods to be retained, which, when the steam is allowed to continuously escape and the vessel to repeatedly boil over without catching the overflowing fluids are largely wasted.
By constructing the main body part 1 of the vessel of tapering formation properly proportioned with relation to the sheet 5 left in making the trough 5, as hereinbefore described, and constructing the bottom 10 of the vessel from this sheet 5', the waste of metal is minimized. It will be understood that the vessel may have any suitable shape, either circular or of the elongated roundended formation of the clothes boiler hcrein shown as an example, or any other suitable shape, as well as be differently proportioned as to width, length or height. In any such modifications it will be seen that any variation in shape will be given to the trough 5, as well as the bottom of the vessel; and, accordingly, the sheet 10 may be used as herein described with equal facility so long as the proper tapering of the main part 1 of the vessel is provided according to my invention. It will also be understood that the trough construction has its full utility even though the main body part of the vessel be straight from top to bottom as in the part 1 shown in Fig. 1, requiring other material lfor the bottom 10.
Other minor modifications may be 1n ade in adapting my invention to its various uses, and therefore, while I have shown and specifically described certain preferred details of construction, as is required, what I claim as new and desire to secure by Letters Patent is:
1. In a boiler or the like, a container to contain liquid for boiling, having a. wall with an opening therethrough, a trough outside said wall to catch liquid coming from said container and return said liquid to said container through said opening, and a closure for said opening comprising means whereby said closure is withdrawn from said opening under excessive pressure in said container.
2. In a boiler or the like, a container to contain liquid for boiling, having a wall with an opening therethrough, a trough out- -side said wallto catch liquid coming from mensa? said container and returnl said liquid to said container through said opening, and a cover for said container having a part fitting down across said opening, said cover being adapted to be forced up to Withdraw said part from said opening.
3. ln a boiler or the like, a container to contain liquid for boiling, having a Wall With an opening therethrough, a trough outside said Wall to catch liquid coming from Said container and return said liquid to said container through said opening, and a cover having a downwardly extending flange to slidably lit in said container and a laterally extended ledge to bear down on the upper part of said container and limit the downward movement of said cover, and said flange extending across said opening When Said ledge thus bears down, said cover being adapted to be forced up and Withdraw its downwardly extending flange from said opening under excessive pressure in said container, and thereby permit escape of contente of said container through said opening into said trough'.
