Bomna-oLnANsine APPARATUS.

To all whom it may concern:

Be it known that 1, Joint Zones, of the city of Newark, county of Essex, and State of :New Jersey," have invented a new and useful Improvement in Boiler-Cleansing- Apparatus, of which the following is a full, clear, and exactdescription.

My invention relates to'improvements in apparatus for removing sediment,dirt, and fine obstructions from boilers.

The object of my invention is to producev a simple apparatus which can be inserted in a boiler and by which the boiler can be thoroughly cleansed by the mereopening of a valve, provided that steam is on in the boiler. p

My invention is more specifically intended to produce'a pipe system which is controlled by a valve outside the boiler, while the main system is located within the'boiler, and in which the main pipe serves as a suction pipe so that the steam pressure in the boiler will force a rapid current of steam through the suction pipe and causethe'suction to draw 'up from the boiler bottom any'sediment which may have collected there, and discharge the sediment outside the boiler.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference char.- acters'indicate corresponding parts in all the views.

Figure 1 is a sectional elevation of the apparatus embodying my invention, and Fig. 2 is a similar view showing a slight modification of the invention. a

The boiler 10 can be of any usual type, and leading from it, preferably at the top, is a relatively large suction pipe 11 which is controlled by arvalve 12, and which can .be led off to any convenient place to discharge. The pipe extends downward into the boiler to a point near the bottom of the latter, where it connects with a perforated pipe 13, the connection bein by'means of a suitable coupling 14. The pipe 13 liesalong the boiler bottom, and is provided with nu- :merous rather large perforations or-holes 15 through; which sediment in the ,boiler is sucked ii p.

The pipes 18 are preferably bell-niouthed so that there will beta large steam area of pres sure on their mouths, and they are provided with numerous large holes or openings 19,- some of which are certain to come at or near the water line in the boiler. The upper ends of the curved tubes or pipes 18 should projeotabove the water line and into the steam area of the boiler. r v

, Itwill be seen that when it is desired to cleansethe boiler, all that is necessary to do is to openthe Valve 12, whereupon the heavy pressure in the pipes 18 will cause the steam to rush through the pipes and up and out through the pipe 11. As. this action occurs, the swift outpouring of steam will First, itwill suck in through the openings 19. the froth on the top of the water in the boiler, and next it will suck up through the openings 15 any sedimentwhich maybe in the boiler bottom, and so the boilerwill be quickly and thoroughly cleansed.- v It'will of course be understood that the boiler can be provided with any usual feed water devices, and that the water may be that it is being withdrawn from the pipe 11, so that the cleansing of the boiler can be attained without shutting off steam or interfering with any of the ordinary functions of theboiler and its connected apparatus. p

In Fig. 2 I have shown a very slight modification of the apparatus, in which '90;- the curved upper parts of the pipe 13 are' dispensed with. Here the pipe l'3 lis a straight pipe lying, along the boiler bottom. and provided with numerous openings 15; like those already shown, and w thni ples downward so. that the; 1

without affecting the principle of the. inventions p I Having thus fully described my invention,
