SPECEFICATION forming part of Letters Patent No. 692,599, dated February 4, 1902. Application filed September 4, 1901. Serial No. 74,325. (No model.)

T0 LZZ whom t may concern:

Be it known that I, DANIEL N. BAXTER, a citizen of the United States, residing at Vichita, in the county of Sedgwick and State of Kansas, have invented -certain new and usefullmprovementsinBoiler-Oleaners; and I do hereby declare the following to be a full, clear, and exact description ofthe invention,

-such as will enable others skilled in the art to which it appertains to make and use the same.

This invention belongs to the type of steamboiler cleaners which remove the impurities from the water during the circulation of the latter through a case or shell by gravitative action, the heavy particles contained in the water being precipitated in the case or body of the cleaner and collecting therein as sediment, which is blown off at required intervals.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to b e had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view showing .the cleaner applied to a steam-boiler. Fig. 2 is alongitudinal section of the cleaner.

Corresponding and like parts are referred to in both views of the drawings bythe same reference characters.

The drum, shell, or case 1 of the cleaner Amay be of any size and shape and is preferably of cylindrical form and arranged horizontally. A pipe 3 connects the upper portion of the shell at one end with the boiler l l at a point about two inches above the lues, but below the level of the water therein. A

pipe 4 connects the upper portion of the opposite end of the shell with the drum or steamspace of the boiler. A blow-oit pipe 5 is connected to the lower portion ofthe shell at the end to which the pipe 3 is coupled and which4 is diagonally opposite the `point of connection of the pipe 4 with the shell. The stand- 5o pipe 2 passes upward through the bottom or lower portion of the shell and extends ashort 'distance above the top or upperV portion and the projecting end is incased by a pipe 6 and cap 7, the pipe 6 being larger in diameter than the pipe 2, so as to leave a space between the opposing sides of the two pipes for the cir.- culation of water. The pipe 3 may be properly designated as the inflow-pipe and the pipe 2 as the outflow-pipe, and these two pipes are located at opposite ends of theshell or case, thereby providing for a precipitation of impurities from the water during the travel of the latter from the pipe 3 to the pipe 2. The receiving end of the stand-pipe is considerably higher than the delivery end of the inflow-pipe 3. Hence the water must iill the shell l and rise in the pipe or incasement 6 before it can reach the entrance end of the outiiow-pipe 2. The several pipes 2, 3, 4, and 5 are provided with valves 10 in order to control the circulation through the shell or drum.

Then the cleaner is in operation, to facili.

tate circulation and to allow gas to escape the steam-pipe 4 should be open as well as inflow-pipe 3 and outflow pipe 2; but the blow-oft pipe 5 should be closed. When itis required to clean the shell, the valves of the pipes 2 and 3 are closed and the valves of the pipes 4 and 5 are open, andthe steam entering the shellv at one end blows od the sediment through the pipe 5 at the opposite end. By having the pipes 4 and 5 located at diagonally opposite points the steam is caused to travel through the entire length of the shell or drum, therebyA carrying off the sediment and thoroughly cleaning the shell.

As indicated in Fig. 2, the sediment collects more rapidly at the end of the shell txo which the inflow-pipe 3 is connected and accumulates more slowly toward the opposite end to which the outiiow-pipe 2 is connected. This action is due to the quick precipitation of heavy particles in quiet water as soon as the water enters the shell and to the more tardy precipitation of the lighter particles. The dimensions of the shell or drum will be governed by the capacity of the boiler and should be of such linear extent as to insure complete precipitation of all impurities separable by heat and gravitative action.

Having thus described the invention, what is claimed as new is The herein-described boiler-cleaner comprising au oblong shell or drum adapted to be arranged horizontally, steam and blow-off pipes connected to the shell at diagonally opposite points, the steam-pipe being uppermost and the blow-off at the lowest point, an inflow-pipe connected with the upper portion of the shell at the end having the blow-olf pipe, an outoW-pipe at the opposite end of from, substantially as and for the purpose Set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL N. BAXTER.
