MEANS FOR. PREVENTING A ND REMOVING INCRUSTATION FROM BOILERS;

Tooll whom it may concern: I I I .Be it known that I, Aton'zo J. sinuous, a citizen of'the United States, residing at Los Angeles, in the county of Los 'Angeles and State-of California -have inventedcertain new and useful Improvements in Means ior Preventing and Removing Incrustations from Boilers, of which the following is a specification. This invention relatesto means for preventing and flremo ying incrustation from boilers.

with one' or more movable incrustation preventive balls. I

Another object resides in the provision of means for preventing and removingincrustation from boilers embodying such characteristics that by a centrifugal or whirling action there is imparted to the water one or I more .chemical agents capable of accomplishing the .r

purposes set forth.

r A still further object of the invention is to -provide an apparatus constructed-and arranged to deliver ventive body or bodies may be arranged for movement under the influence of the feed water'to continuously I "present particles thereof to the water.

' With the above and other objects in view the presout invention consists in the combination andarrangement of parts hereinafter more particularly referred to shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from thespirit or scope of the invention orsacrificing any of ,the advantages thereof. I I

In the drawings: Figure l is a side elevation of the invention; Fig. 2 is a horizontal sectional view there-' of; Fig. fiis a transverse, vertical sectional of the mixing chamber; Fig. 4 is a sectional ,view of one formlof incrustation preventive ball; and Fig. 5 is a sectional view of another incrustation destroyer and preventive ball provided with I numerous perforations and" alsoshowing a' shield used when filling theball w'ith -chemicals.-

6 is a sectional view of, a thir form of incrustation preventive ball.

I Specification of Letters Patent: Application filed ootoher '25, 1906. Serial No. 346,569-

One object is to dispose in the means for conveying feed water to a:,boiler a suitable chamber provided outl Patented Oct. 1 1907.

3 connecting w'ith the neck 4 of the mixing chamber 5 and secured thereto v in any suitable manner, the

mixing chamber 5 communicating'withthe boiler 6 by way of the pipe 7. I I

The mixing chamber 5 is preferably circular in form,

although it maybe of any other shape, and is provided with inner v and outer walls 8 and 9, respectively, to.

form a race-way for the-guidance of the balls 11 whirled continuously through the race-wary bythe water under pressure from said pump or other source.- Thus it will be understood that thewater and balls travel rapidly. through the race-way, and in operation it will be seen that part of the water in its whirl through the race-way falls behind the balls 11 and passes through the V- shaped or other formof slot 12 and'into the pocket 13' to the boiler by way of the aforesaid boiler connecting pipe 7. v

The water fed into the boiler by my improved apparatus is sometimes heavily charged with impurities,

but be that'as it may, I have found that by using certain chemicals the water may be so treated as to overcome the formation of incrustation or other scale upon theinterior of the boiler. I have also found that my invention will satisfactorily remove from boilers any incrustation or scale formed thereupon prior to the use of my apparatus. To accomplish-such results -the chemicals should bethoroughly intermingled with the water and to'insure this-thorough intermingling of the chemicals and water I formthe balls 11 hollow that they may be adapted to carry the chemicals,- and I provide each ball with a perforation 14 through which chemicals may be inserted and through. which the chemicals may be discharged from the ball due to the centrifugal action of the balls in operation. In one.

embodiment of my invention, I employ a composition consisting of hemlock extract and soda-ash-with or 'without water. These chemicals are thoroughly mixed with the water and in a semi-liquid orpaste state; the composition thus compounded is inserted into the ball .11 through the perforation 14 and allowed to dryandharden. When the balls areready for use, that is,

after the compound has been hardened by heating.

serted in the mixing chamber 5 through the opening 15 which is normally closedby the cap 16 them or in any other suitable manner, the balls are in-.-

' The water whirling the balls around the race-way oi' the mixing 'chamber causes the centrifugal action of the balls to slowly give out the chemicals contain-ed therein, r

the water-in its passage through the race way of course entering the opening 14 and softening the hardened.

composition within the balls. The openings 14 .'are of small size to permit a slow discharge of the chemicals. I 1

I: do not limit myself tn the nature of chemicals. employed, for in addition to the above mentioned com- .pound, l might employ bicarbonate of soda, Glaubers salt, sal-soda, config salt and, potash; or red lead,

vide a comp-erstively hard but brittle ball.

might add New Orleans molasses or fiour or both to any one of the above compounds, especially to the last RIO 'ticulzir case I am claiming gegement of the shells or bells withthe'wzills of the" mixing chamber, smell particles of iron ere given off from the shells 01" balls 'and taken up by the Water to intermingle ivith the chemicals discharged from the balls, although, of course; the above mentioned sepsrete sets of chemicals combined in the manner stated will effect the desired results. if preferred, 1 might provide a ball or other body a shown in Fig. 6 com-' posed of any one of the albovo or other compounds in combination with smallpsrticles of iron,'the whole ball intime Wearing away. necessitating insertion in the mixing chamber of new balls. ln'tlus last compound, tho-ingredients might be molded, pressed or otherwise forced into intimate CODllZtCt with one another to pro- Further, I

named compound.

In Fig. 5 I illustrate-2i chemical carrying ball 17 provicled with numerous perforations l8. Th s hall performs the same functions set forth for the ball 11,'-and in order to facilitate filling of the ball 17 I may employ a cup shaped support 19. i

The operation of the invention will now be stated briefiyus lollowsz wnter under pressure is forced into the mixing chamber 5 where it is whirled around in the chamber to move the balls rapidly therethrough and to cause the bollsto give off such proportions of chem icals to intermingle with the Water passing through the pipe 7 into the boiler 6 to positively prevent or remove incruststion formed upon the wells oi the boiler.
