BOILER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 550,521, dated November 26, 1895.

Application filed July 13, 1896.

To aZZ whom it may concern:

Be it known that I, DAVID MYERS, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Boiler-Cleaners, of which the following is a specification.

This invention relates to certain new and useful improvements in boiler-cleaners, and refers more particularly to that class of boiler cleaners in which the refuse is collected by a skimmer and expelled from the boiler, being carried outwardly through a tube into a settling drum or chamber; and the invention consists in a skimmer supported upon a sleeve, which sleeve is in turn supported by floats in position to receive the refuse from the boiling water, the sleeve being retained in position by means of the pipe which conveys the refuse out of the boiler.

The invention also consists in the use of an auxiliary separator located in the settling drum or chamber, whereby the refuse which is carried into the settling-chamber may be separated from the water which is returned to the boiler, the device being so constructed that the refuse and the water carried from the boiler are deposited in a settling drum or chamber and the refuse is left in the settling drum or chamber while the water is returned to the boiler; and the objects of my invention are, first, to thoroughly and efficiently separate the refuse from the water in the steamboiler; second, to provide a skimmer which will automatically adjust itself to the proper position within the boiler to receive the refuse and to remove the same therefrom; third, to combine with the settling-drum an auxiliary cleaner or separator constructed substantially as described. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a sectional View of a steamboiler, showing my improved skimmer and also showinga settling tank or chamber with my improved separator arranged therein.

Fig. 2 showsa plan View of a skimmer constructed in accordance with my invention de- Serial No- 555,889. (No model.)

tached from the tube which conveys the refuse from the boiler. Fig. 3 shows a sectional View on line Y Y of Fig. 2, showing the position of the skimmer and floats with reference to the exit-tube which conveys the Water andthe arrows showing the direction taken by the water and refuse in their passage from the boiler.

E represents the settling-drum, which receives the refuse from the boiler, and F represents the return-pipe, which conveys the water from the settling-drum back to the boiler.

B represents the skimmer, which is composed of a series of open passages leading from the periphery of the skimmer to a central point-that is, to the head or socket K.

B B represent the passages placed above the skimmer, which direct the water and refuse to the openings 1) b, which openings allow the refuse to pass into the socket K. I prefer to construct my skimmer with siX of these passages B B but the number maybe varied. The socket K fits loosely upon the lower end of the conduit-pipe O, and the skimmer, to-

gether with the socket K, is held at the proper position in the boiler by means of the floats H H. In the drawings 1 have shown four of these floats; but the number may be varied, and the operation of this part of my invention is such that as the water is raised or lowered in the boiler the skimmer is raised and lowered and always retained in the proper position to receive the refuse, which rises and is carried by the currents of water in the boiler. I also provide at the lower end of the pipe G small holes which will receive the water and refuse into the pipe 0, from whence they are carried outwardly, as above described.

The bottom of the socket K is closed while the bottom of the pipe 0 is preferably left open. By this construction I provide a skimmer which is automatically adjustable to the required position at all times and dispense with everything in the shape of a joint or hinge, the skimmer-floats moving freely up and down, being retained in that position merely by the lower end of the pipe G.

I prefer to construct the conduits B B with their upper surfaces on a curve, as shown, while the skimmer proper forms the bottom of these openings.

D represents a cone-shaped enlargement at the lower end of the pipe 0, and the same receives the refuse and water which are carried through the pipe 0. I prefer to make the cone-shaped part D integral with the refuseseparator and not integral with the dischargepipe. This, however, is merely a question of convenience in construction.

N N N are a series of funnel-shaped receptacles placed around the cone-shaped opening 1), and the water and refuse which are conveyed to the settlin g-drum through the pipe 0 pass down between the funnel shaped receptacles N N N,and the water in returning passes around the outer rim of the series of funnels N N N, as shown in Fig. 1 by the arrows, and any refuse which remains in the water passes into these receptacles N N N, from which it drops down by gravity through the dischargepipes P P, &c., and settles to the bottom of the settling-chamber. In the example of my i11- vention shown in the drawings I have shown six of these receptacles N N N; but the number may be varied.

The settling-chamber E may also be provided with suitable means for drawing off the refuse at the bottom; but inasmuch as such devices are old I have not deemed it necessary to illustrate them in the drawings.

In order to retain the separator in proper position in the settling-drum, projections Q Q may be used of suflicient length to meet the walls of the settling-chamber E. This will allow the water to rise freely around the outer rim of the separator to pass over and become deposited in the funnel-shaped receptacles N N N.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is-

1. In a steam boiler cleaner, the combination with a settling chamber, of a pipe leadin g from within the boiler to the settling chamber, and a skimmer adj ustably supported upon the end of said pipe within the boiler, and consisting of a receptacle having a fiat bottom and divided into a plurality of coneshaped vessels having their small ends sewhich are arranged around and connected to said sleeve and forming a passage from the boiler to the latter, and a float or floats connected to said cone-shaped Vessels, substantially as described.

3. In combination with a boiler, a settling drum, a plurality of funnel-shaped receptacles within the settling drum, a suitable opening receiving the water and refuse from the boiler and conveying the same to a point below the said funnel-shaped openings, a casting supporting the said funnel-shaped receptacles of form to correspond substantially to the inner shape of the settling drum, openings at the bottom of each of said funnelshaped receptacles for the discharge of the refuse gathered therein, and a return pipe adapted to convey the water freed from the refuse from the settling drum back to the boiler, substantially as described.

i. In combination with a settling drum, an inlet pipe, an inverted funnel placed within the said drum in which the said pipe opens, a series of funnelshaped receptacles supported within the said drum and having open ings for the discharge of the refuse toward the bottom of the said drum, a broad opening at the top for the reception of the refuse received from the water arising from the drum to the pipe which conveys the water back to the boiler, substantially as described.

5. In combination with a drum, an inlet pipe, an inverted funnel into which the said inlet pipe opens, an opening at the bottom of the said funnel, a series of funnel-shaped receptacles surrounding the said opening, a space between the said funnels and the inner periphery of the settling drum allowing the water to pass upward and over the said funnel-shaped receptacles, and a return pipe adapted to convey the water from the said settling drum to the boiler, substantially as described.

6. In a steam boiler cleaner, the combination with a settling tank or chamber, of a pipe leading from within the boiler to within the settling tank, a floating scum-remover freely surrounding the end of the pipe within the boiler, and consisting of a plurality of radially arranged cone-shaped vessels connected to a sleeve which surrounds the end of the outflow pipe and forming passages from within the boiler to said pipe, an auxil- IIO iaryseparating device arranged upon the pipe hand and seal in the presence of two Wit- Within the settling tank and consisting of a nesses.
