APPARATUS FOR INSTANTANEOUS STEAM-GENERATION.

SEEGIFICAIION forming part of Letters Patent No. 445,222, dated January 27, 1891.

Application filed August 11, 1890. Serial No. 361,660. (No model.) Patented in Germany March l3 1890 N0. 51,952-

To all whom it may concern.-

Be it known that I, HERMANN FRIEDRICH CONSTANTIN Hess, a subject of the Duke of Anhalt, German Empire, residing at Bernburg, Duchy of Anhalt, German Empire, have invented new and useful Improvements in Apparatus for Instantaneous Steam-Generation, (for which I have obtained Letters Patent in Germany, dated March 13, 1890, No. 51,952,) of which the following is afull, clear, and exact description.

The apparatus hitherto employed for cleaning conduits for liquids, and especially beerconduits, consists of a steam-boiler mounted on a wagon, which is driven to the locality, and is connected by means of a long rubber hose to the beer-condu1t. The steam is then generated in the usual way by heating and passes through the hose into the conduit. This process is not only tedious, but renders the proprietor of the saloon dependent upon the people making this cleaning their business. Moreover, it can only be carried into practice in larger cities, as only there a business of this character could exist. Another important drawback is that the steam is considerably cooled off on its way to the beerconduit, so that only after a comparatively long action of the steam is the sterilization of the conduit obtained. These disadvantages make the hitherto usual manner of cleaning the beer-conduits not only very inconvenient and unreliable, but also highly unprofitable for the saloon-keepers.

The object of my invention is to remedy these disadvantages by the construction of a steam'generator which can be used by every saloon-keeper without a license for the use of boilers and at small expense for the cleaning of his beer-pipes. I have illustrated an apparatus of this nature in the annexed drawings, which form a part of this specification, and wherein- Figure 1 shows a side view, partly in section, of the generator. Fig. 2 shows a side View of the generator and one manner of feeding the same, and Fig. 3 shows the application of the apparatus to the cleaning of beer-pipes.

My invention comprises, primarily, an iron or copper block or bolt which is adapted to be placed in a red-hot condition within a very strong cylinder, wherein water is fed at the top to generate steam, or at the bottom when it is desired to produce superheated steam. The cylinder A, preferably made of wrought-iron, phosphor or manganese bronze, and closed at its lower end, is provided at its upper end with a steam-tight closing headpiece B, carrying one or two discharge or exhaust pipes 11 I). Closely to the bottom of the cylinder A is arranged a cock at, which connects through hose g with a pressure-pump or high-pressure water-conduit. If two discharge-pipes b b are arranged on the headpiece B so that two conduits can be cleaned simultaneously, only one of the dischargepipes will be provided with a cock 0, thus preventing, even with the highest steam-pressure, an explosion of the generator. 1

If the apparatus is only intended to clean one conduit, and is consequently provided with only one discharge-pipe, I prefer for safetys sake not to arrange a cock in this discharge-pipe.

The wrought-iron or copper block or bolt D is preferably formed with a projection cl, in which a circular groove is provided, or a transverse hole is drilled, so as to allow of its convenient insertion by means of a hook into the cylinder when heated red-hot.

The cylinder A can be provided with feet, or preferably with a stud E, resting in abearing 0, secured to some part of the bar, Figs. 1 and 3, so as to allow of a rotary motion being imparted to said cylinder.

The operation of the apparatus is as follows: After removing the head-piece B the block or bolt D is taken out of the cylinder A and heated in a fire. This can be conveniently done in the kitchen. fire, which will be in most cases always ready for this purpose. The red-hot block or bolt D is then inserted into the cylinder A, and itis preferable to make its lower end rest on a stud, as shown in dotted line f, Fig. 1, so thata small space is provided for the water between the lower end of the block or bolt and the bottom of the cylinder. The block or bolt is constructed so as to leave a small space free between its outer surface and the inner wall of the cylinder. After screwing the head-piece B steam-tight on the cylinder A and connecting the discharge or exhaust pipes 12 and b by means of rubber hose (0' with the mouth-pieces of the draftcocks F F, Fig 3, I admit water into the cylinder by the way of the feed-pipe g and the cock a. The red-hot block or bolt D will at once convert the water coming in contact therewith into steam, and as the steam will travel upward alongside the hot block or bolt only perfectly dry superheated steam will pass into the beer-conduit. As the steam is generated instantly upon the feeding of the water and the block or bolt D is heated and placed in the cylinder A before the rubber hose is connected to the draft-cocks, the whole cleaning process, during which no beer can be drawn, will only take about one minute and a half. Consequently the bar-keeper will be able to clean the beer-pipes at any time,-

even during the busiest time of the day.

In the process as just described I have taken it for granted, of course, that a highpressnre water-pipe or a pressure-pump were available to force the water into the cylinder. It may happen, however, that these features are not available in some places. In order to render my apparatus also applicable in such places, I have devised the arrangement shown in Fig. 2. Alongside the cylinder A, I have arranged a water-receptacle G, the bottom of which connects through pipe g with the lower part of the cylinder A, while its upper end connects through pipe g with the upper end of the said cylinder. On the water-receptacle G, which is closed at both ends, I have provided a funnel H, connecting by means of the cook it with the receptacle. The feed-pipe g is provided with the cook a. The receptacle G is filled with water to the mouth-piece of the pipe g, the cock at being meanwhile kept closed. Subsequently the cock h is also closed. After inserting the redhot block or bolt D in the cylinderA, closing the head-piece B, and connecting the discharge or exhaust pipes 17 and b by means of rubber hose a to the draft-cocks F F, the feeding-cock at is opened. The water flows from the receptacle G under thehot bolt D, and evaporates partially by contact and partially by radiation, and the steam thus produced will then flow through the beer-conduits. As during this process part of the steam will also pass through pipe g and enter into the receptacle G above the water, the pressure at the lower end of the water column will be relieved, and the water can consequently flow into the cylinder A. As thus constructed, the apparatus may be used by the saloon-keeper without the aid of a pressure-pump or a high-pressure water-conduit. As in consequence of the direct contact of the water with the'red-hot iron a large quantity of oxide is formed, which will loosen itself and collect on the bottom of the cylinder A, it will be desirable to arrange the latter so that it may rotate on the stud E. Before inserting the hot block or bolt the cylinder is reversed, so that the oxide may be removed. This generator can of course also be used for purposes other than the one described, where it is desired to have a very quick and only temporary generation of steam.

Having thus described my invention, whatl claim as new, and desire to secure by Letters Patent of the United States, is-
