This invention relates to distilling" apparatus and more particularly to a boiler in which water may be converted into steam which is allowed to pass out of the boiler and through a pipe to a suitable condenser.

One object of theinvention is to provide a boiler in which the heating. chamber is enclosed in a water jacket and the water fed from the water jacket into tubes disposed within the heating chamber so that the water maybe quickly heated to a high temperature and converted into steam. V

.Another object of the invention is to permit products'of combustion or an equivalent 16 heating medium to pass upwardly through the heating chamber between and about the water tubes and also provide conduits :tor the heating medium which extend vertically through the tubes and thereby cause the water tubes to' be quickly heated to a very high temperature and maintained at this temperature so that'the water will be heated and converted into steam in a very eificient manner.

Another object of the invention is to provide a boiler which will be simple in its constructionand consist of a comparatively few number of parts.

Another object of the invention is to arrange the water tubes in banks which are disposed in the heating chamber and securely mounted in communication with the water jacket.

Another object of the invention is to allow a portion of the heating medium to pass up wardly, through conduits disposed in the water acket about the sides of the body and thereby allow the water in the water jacket to be pre-heated before it enters the water tubes in the heating chamber.

' Another'object of the invention is to cause steam which accumulates in the upper portion of the water jacket to be kept hot and thereby prevented from condensing in the water jacket.

The invention is illustrated in the accompanying drawings, wherein W Y Figure 1 is a vertical sectional view through the improved boiler;

Fig. '2 is a transverse sectional view through the boiler taken in the line 2- of Fig. 1; i

Fig. 3 is a vertical sectionalvview showing a slightly modified form of boiler, and

modi fied form of boiler.

Fi 4 is a similar .view showing another The improved boiler which is intended to form part of a still includes a body por tion 1 which is formed of metal and has a tapered top or upper portion 2 from which extends an outlet neck 8. The body defines a heating chamber which is open at its bottom, as clearly shown in Fig. '1, so that it may be placed over a fire and products ofeombustion or heated air'constitutinga heating medium passed upwardly through the body and out through the neck 3 which may constitute a smoke pipe if so desired and have suitable connection with a chimney or the like. It will, of course, be obvious that,

if desired, the boiler may be set'in place upon an ordinary cooking stove of the coal or gas type. A bafile 4 is mounted in the upper portion of the body and maybe adjustable toward and away from the lower end of the neck 3 so that the warm air 'or products of combustion in the upper portion of the chamber may be directed toward the walls thereof and prevented from passing into the outlet neck too rapidly.

A water jacket 5 is disposed about the body 1 in spaced relation thereto, as shown in Fi 2, and has its lower end closed by an inwar ly extending flange or bottom 6 and its upper portion 7 tapered and terminating in a head or dome Swhich is disposed about the outlet neck or pipe 3 and formed with a side opening in which is fitted a pipe 9 to conduct the steam to a suitable condenser. From an inspection ofFig. 4, it will be seen that, if desired, pipes 10 may be disposed vertically in the water jacket at opposite.

sides of the body with their upper and lower end portions bent to extend toward the body. These end portions 11 of the pipes 10 are fitted into openings formed'in the side walls of the body, and it will be readily seen that the heating'medium by passing through the pipes 10 may heat: the water in the water jacket before it passes out of the water jacket. A water inlet pipe 12 which may lead from any suitable source of supply is connected with the water jacket as shown in-Fig. 1 and provided with a control valve '13 and a water glass 14 is connected with the water jacket in the usual manner so thatthe' amount of water'in the boiler may be determined by looking at the water glass and additional water fed into the water jacket when necessary by opening the valve in the supply pipe.

A series of'water heating units is disposed.

in the chamber defined by the body 1 and each includes an upper tube '15 and a lower tube 16. These tubes extend transversely in the chamber with theiropenend portions passed through openings in side walls of the body and communicating with the water and up into the tubes 17 until it reaches and enters the upper tubes 15. The normal water levelis indicated by a dotted line in Fig. 1' and is preferablybelow the upper walls of the upper tubes as shown so thatsteam may pass from these tubes into the water jacket and accumulate in the tapered upper portion thereof about the tapered top of the body and about the outlet pipe 3.. By this arrangement the hot outlet pipe and up per portion of the body will retain the steam at a high temperature and prevent it from condensing in the upper portion of the water jacket before it has an opportunity to pass out through. the pipe 9 to the condenser. If .so desired, additional transverse pipes 18 maybe disposed in the chamber between the upper and lower pipes, as shown in Fig. 3. It should also be noted that the upper and lower pipes may .be staggered, as shown in Fig. 4, so that the heating units may be placed somewhat closer together than shown in Fig. .2 and thereby allow a greater number to be accommodated in the heating chamber while at the same. time leaving sulficient space between them for the heating medium to pass upwardly through the chamber.

Conductor tubes 19 for the heating medium extend longitudinally through the vertical ly disposed pipes-17 and have open upper and lower ends which pass through openings formed in the upper and lower walls respectively of the upper and lower tubes 15 and 16 and communicate with the upper and lowe-r end portions of the heating chamber. Therefore, the heating medium in addition to passing upwardly about and between the heating units may also pass upwardly through the tubes 19 and constitute internal :means for applying heat to water in the heating units. 'By this arrangement the water in the water tubes will very quickly reach the boiling point when the boiler is in use and the water caused to boil at such a ratethat it will be very quickly converted into steam. As previously explained, this steam passes outwardly through the ends of the upper tubes into the water jacket and upwardly through the water jacket into the dome 8 from which it passes through the pipe 9 .to .a suitable condenser. When necessary, one or more of .the heating units may be removed :so that fit :can'iberepaired or replaced with a new one.
