UNITED STATES PATENT OEEIGE.
DAYID A. MORRIS, OF NEW YORK, N. Y.
STEAM-GENERATOR.
Specification forming part of Letters Patent No. 106,392, dated August 16, 1870.
My invention relates to upright steam-boill ers; and consists in certain improvements thereon, which will be particularly described and pointed out hereinafter.
In the accompanying drawing, Figure lrepresents an elevation ofthe boiler, showing an outside view of the outer coils, but a sectional View of the steam and water chamber, and also of the furnaces, as through the lines a: :v of Fig. 2. Fig. 2 is ahorizontal section of Fig. l through the line y y, the left-hand portion of the tgure being a top View.
Similar letters of reference indicate corresponding parts.
A is the steam-chamber. B is the waterchamber. These chambers are made of any required size, and of boiler-iron of suitable thickness and strength. These chambers are connected by a series of coils, C, or tubes coiled spirally, one coil within another. Each tube is coiled wide, or with a great pitch, in order to give a free movement to the water, and each coil consists of several tubes, so as to nearly ll up the whole space between the chambers, as seen in Fig. 2. The coils are made of ditferent diameters, and placed one within another, and the size or capacity of the boiler is varied by the number of coils used.
I am aware that pressure has a tendency to straighten out a coil, and to counteract this tendency I make my coil both right and left handed, alternately, as seen in Fig. 1. By connecting the steam and water chambers in this manner, the expansion and contraction produced by the heat does not affect the `joints. There straight tubes have been used it has been found im possible to keep the joints tight, owing to unequal expansion and contraction.
rI he boiler-plates which I vuse inconstructing my chambers, it will be seen, are formed into plain cylinders, and, by making my generating-tubes spiral, any movement produced by expansion or contraction does not affect the tube-sheets.
I produce an active circulation through the coils by means of circulation-tubes D, (four, more or 1ess,) which connect the chambers together, and which pass from one chamber to the other outside of the jacket E, so that they are not exposed to the tire, and so that no steam can be generated in them to impede the downward passage of th water.
Frepresents thel waterjine. Gr is the crownsheet. The circulation tubes D are seen in dotted lines in Fig. 1. The ends of the tubes which form the coils pass up through or above the water-line, with goose-necks thereon, for throwing the current of steam and water in a lateral direction, or against the sides ot' the chamber.
H is a pipe, which extends down through the steam-chamber A, and downward through the centerof the coils to near the water-chamber B, as seen in dotted lines in Fig. 1. This pipe is exposed to the action of the nre below the crown-sheet. Within this pipe H is the steam take-out pipe I, and this arrangement of pipes I call my superheater. The steam from the chamber A enters the pipe H through the apertures J, and, passing to the bottom of that pipe through the annular space K, it enters the take-out I, and ascends, from whence it is conducted to the engines or for use. This arrangement prevents priming entirely, and thoroughly prepares the steam for use.
A very important feature of my invention is the arrangement of the furnaces for the coinbustion of thevfuel.
L L represent the furnaces. One or more furnaces may be employed, placed near the upper end of the steam-generating coils, outside of the jacket E, substantially as seen in the drawing. The smoke and heated gases pass through the jackets at the points M, and descend among the coils, passing around the water-chamber B into the tlue N, by which it is conducted to the chimney. The feed-water is introduced into the chamber B, and rises to the water-line F, lling the coils, and being discharged from them mingled with steam, and returned again to the water-chamber bythe circulation-tubes D, as before stated.
I do not confine myself to any particulars as regards the details of construction.
My invention is illustrated in the drawing and described above, my object being` to produce a safe, cheap, and durable boiler, and one economical in fuel.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. Making coils for steam-boilers, to consist of two or more threads, substantially as above set forth.
2. Connecting two separate chambers by means of coils, as described, one being a Water and sediment chamber, and the other a steamchamber.
