HENRY SIMS, OF ERIE, PENNSYLVANIA.

AUTOMATlC BOILER CLEANER.

ffiPECIPICATION forming part of Letters Patent I 1'0.344,925, dated July 6, 18186.

Application filed February 25, 1886. SerialNo. 193,248. (No model.)

To all whom it may concern:

Be it known that I, HENRY Suns, a citizen of the. United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new. and useful I1nprovements in Automatic Boiler-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains, to make and use the same, reference being had to the accompanying draw- 1ngs, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to boiler-cleaners; and it consists in the improvements hereinafter set forth and explained.

My invention is illustrated inthe accompanying drawings, in which Figure 1 is a View, partly in elevation and partly in section, of my invention, showing the same attached to a boiler. Fig. 2 is a perspective view of a portion of my invention and of a section of the boiler to which it is attached, portions of the boiler being broken away, showing the opeirmouthed pans and their arrangementin the boiler, and also the arrangement of the discharge-pipe supporting the same.

Like letters refer to like parts in all the figures.

In constructing my improved boiler-cleaner, I make one or more triangular open-mouthed covered pans, A, according to the size of the boiler B, in which they are to be placed. The mouths of the pans A are made wide enough to occupy as much of the width of the boiler B at the normal level of the water therein as possible, and the mouths of these pans are made of suiiicient height, so that they will embrace the highest and lowest normal level of the water in the boiler. The bottoms of the pans A are placed nearly or quite level. The tops, however, slope from the open mouths thereofdownward, and the perpendicular sides toward each other to the points 00, where they are coupled toa T, D, on the dischargepipe E, which projects through the top of the boiler B. These pans A may be made in sections, of any suitable and convenient size, which can be readily insertedthrough'the manhole of a boiler, and bolted together after they are inside of the boiler. The pans A are located preferably as near as possible to the back end of the boiler 13, with their open months toward the front end of the boiler and toward the point where the fced-water pipe discharges, which I preferably locate near the surface of the water in the boiler, directly in front of the open'mouths of the pans A.

At the rear of the boilerarch, or at any convenient point, I place an upright settling-tank, F, which is of any convenient height; but I preferably make it so as to extend from the floor to a height equal to that of the top of the boiler B, substantially as illustrated in Fig. 1. I connect the discharge-pipe E by means of suitable connections, E, to this settling-tank F at a point, G, preferably about one-half of the distance vertically between the top and bottom of the tank F, so that the mud and other material discharged from the boiler will settle downward to the bottom of the tank F, where it can be blown off through a blow-off cock, H, placed therein for that purpose, leaving substantially clear water above the point G. The connection E of the discharge-pipe Eis also provided with a cock, G, near the tank F, by means whereof the connecting-pipe Fl may be shut off when desired.

At'or near one side of the rear head, B, of the boiler B, I insert a delivery-pipe, Lwhich extends outwardly from the head B ashort dis tance, where an elbow, J, is coupled thereto, into which a section thereof. 1', extends horizontally across the head B a short distance therefrom to a pointon the opposite side thereof, where by means ofan elbow, J, the connection I is turned back through the rear of the brick arch-work K, from which point, by means of suitable connectionsJ, the deliverypipe I is connected with the upper end, preferably the top F of the settlingtank F. This connecting-pipe I is also provided with a valve, 1, so that it can be shut off when desired. The end of the pipe P, where it eX- tends into the settling-tank F, is preferably provided with a screen, L, to prevent light particles of matter which have been once discharged into the settling-tank F from being drawn back into the boiler.

The operation of my improved boiler-cleaner is automatic, it being operated by means of the action of the fire upon the section I,crossing the rear boiler-head, B, which superheats the water therein, thereby producing a our- ICO rent from the top of the settling-tank F into the bottom of the boiler, which operates to draw the water and impurities raised to the surface thereof by the operation of boiling into the pans A, from whence it is conveyed through the discharge-pipe E and its connections E into the settling-tank at G,this action being constant while the boiler is being operated. The water in the tank being cooler than that-in the boiler, the impurities held in suspension are speedily precipitated to the bottom of the settling-tank F by the cooling of the water, leaving the water in the upper part of the tank F, where it is being conveyed back to the boiler by the pipes I and I, comparatively free from impurities, so that I am enabled to practically remove the greater part if not all of the impurities from the water, without the intervention of a separate heater or other device than that hereinbefore described.

I am aware that devices having some of the characteristics of my invention have been heretofore constructed for example, the device of Kemp,shown in his Patent No. 166, 782, dated August 17, 1875. This device,however, differs materially from my invention, both in its construction and operation, viz: In Kemps device the settling-tank is a comparatively shallow tank, located above or on the top of the boiler, having its inlet and outlet pipes entering it on the same level, no means being provided for superheating any portion of the outlet pipe on its return to the boiler. Again, the funnel ends of Kemps outletpipes have comparatively little skimming capacity, and that capacity is constantly varying with the height of the water in the boiler, while in my device the settling-tank is located at one end or beside the boiler, and is of very considerable depth vertically, and has its inlet-pipe near its center vertically, and an outlet-pipe at its top, which cutlet-pipe passes through the fire-chamber, entering the boiler near the bottom at its rear end,

whereby it is superheated. The pans in my device also differ substantially from Kemps in both shape and operation. Their sides being vertical, much wider pans may be used, and their skimming capacity is always the same without regard to the height of the water in the boiler.

In the construction shown I show a convenient construction and arrangement of the the parts of my device, and suitable means for connecting the parts together; but these may all be varied to suit the shape or location of the boiler to which they are to be applied without departing from the spirit of my invention.

Having thus fully described my invention, so as to enable others skilled in the art to which it appertains to construct and use the same, (what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination, in an automatic boilercleaner, of one or more covered pans opening at one end,and located in the boiler about the water-level, substantially as shown, with an upright settling-tank provided with ablow-off cock near the bottom thereof, and a pipe connecting the ends of said pans in the boiler with the said tank at or near the center vertically ofthe tank, and also a pipe extending from the upper end of said settling-tank across the firechamber and into the rear end of the boiler near the bottom thereof, substantially as and for the purpose set forth.

2. The combination, in an automatic boilercleaner, of one or more triangular covered pans open at the large ends thereof, and located in the boiler about the water-level, substantially as shown, with an upright settlingtank provided with a blow-off cock near the bottom thereof, and a pipe connecting the small ends of said triangular covered pans in the boiler with said tank at or near the center vertically of the tank, and also a pipe in the upper end of said tank provided with a screen and extending therefrom into the fire-chamber and acrossthe rear end of the boiler, and entering the same at or near the bottom thereof, substantially as and for the purpose set forth.

3. In an automatic boiler-cleaner, the triangularflat-bottomed and perpendicular sided covered pans A, the T D, connected to the small ends of the pans A, and the dischargepipe E, in combination with the boiler B, substantially as and for the purpose set forth.

4. In an automatic boiler-cleaner, the upright settling-tank F, having a blow-off cock, H, near the bottom thereof, and an ingresspipe entering the same at G, and an egress-pipe near the top of said tank F, all substantially as and for the purpose set forth.

5. In an automatic boiler-cleaner, the combination, with the upright settling-tank F, of an egress-pipe near the top thereof provided with the screen L, substantially as and for the purpose set forth.

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

HENRY SIMS.
