PU RIFIER FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 458,836, dated September 1, 1891.

Application filed April 28, 1891. Serial No. 390,741- (No model.)

To all whom it may concern.-

Be it known that JAMES E. KINTZEL, deceased, late a citizen of the United States, and a resident of La Junta, in the county of Otero and State of Colorado, did in his life-time invent certain new and useful Improvements in Purifiers for Steam-Boilers; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to purifiers for steamboilers; and it has for its object to remove the scum from the boiling water, so as to prevent the impurities therein from settling upon the back flue-sheet and the flue-pipes, whereby all tendency to incrustation or scaling will be effectually prevented.

A further object is to provide means for automatically removing all mineral or earthy deposits which may accumulate in the mudring.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claim.

In the drawings, Figure l is an elevation of a locomotive-boiler, partly in section, showing the position occupied by the improved purifier. the sectiorrline being taken immediatelyback of the back fiue-sheet, showing the purifier and also the mechanism for removing the mud from the mud-ring. Fig. 3 is a detached view of the purifier removed from the boiler.

Referring to the drawings, A designates the boiler, and B the back flue-sheet. Arranged within the boiler at a point adjacent to the back flue-sheet and resting upon the fluepipes C is the purifier or skimmer-tube, which consists of a closed-end tube or cylinder I), the upper surface of which is provided with a number of perforations 1. Along each side of these perforations are secured a series of knees 2, which serve as guides for a slide E, which is also provided with a series of per- Fig. 2 is a perspective view in section,

forations 3, adapted when the slide is moved to the proper position to register with the perforations in the cylinder. The outer end of the slide extends through the boiler-shell and is provided with a handle 4..

F designates a discharge-pipe, which connects with the cylinder at or near the center of one side thereof. This pipe is curved outward and then downward and extends to within a short distance of the ground.

G designates a valve carried by the discharge-pipe. To the handle 5 of the valve is attached a rod 6, which extends Within the cab, so as to enable the engineer to open or close the valve at will.

II designates two siphon-pipes, which are tapped into the discharge-pipe and extend to the sides of the fire-box I and pass down between the said bOX and the boiler-shell .l. The lower ends of the pipes are bent backward, so as to lie in the mud-ring K, and these horizontal portions 7 are perforated, as at 8.

In carrying the invention into effect the cylinder is so arranged in the boiler that its upper surface will be slightly below the surface of the water, and being located near the flue-sheet, at which point there is the greatest accumulation of scum, owing to the intense heat, it follows that as soon as the slide is moved to bring its perforations in register with those in the cylinder the scum will escape through the escape-pipe to the ground. As long as the purifier is in operation the siphon-pipes H will remain inoperative; but as soon as the slide E is moved so as to close the openings in the cylinder the steam-pressure in the boiler will cause these pipes to siphon or suck the mud or other accumulation from the mud-ring and discharge it through the pipe F to the ground. WVhen it is not necessary to use either the purifier or the siphonpipes, the valve G is closed, thus rendering the device inoperative.

I am aware that heretofore devices for re moving scum have been used in boilers; but I am not aware that previous to this invention a skimmer-tube has been placed transversely of the boiler and adjacent to the back fluesheet. By arranging the skimmer-tube as just stated a very superior result is achieved as compared with the arrangement of a skimming device longitudinally of the boiler or transversely at a point remote from the back fluesheet. It is well known that the greatest intensity of heat is at the back flue-sheet, and that consequently the greatest amount of scum is generated there. Now should the skimmer-tube be arranged longitudinally of the boiler it would serve to gather the scum in its immediate vicinity only, and consequently its operation to that extent would be defective. Again, should a skimming device be placed transversely of the boiler, but at a point remote from the back flue-sheet, the scum back of the skimmer would find its way to the steam-dome and there clog the throttle. These faults are effectually remedied by this invention, for as the skimmer-tube is arranged transversely of the boiler at its rear end no scum can reach the dome and dry-pipe without passing over the skimmer, and in doing so it will be drawn off.

WVhat is claimed as the invention of the said JAMES E. KINTZEL is- In a steam-boiler, the eombination, with the back flue-sheet and the mud-ring, of a closedend cylinder arranged adjacent to and parallel with the flue-sheet and having a series of perforations extending alongits upper side, a slide arranged on top of the cylinder and having perforations adapted to be movedinto and out of register with the perforations in the cylinder, a valved discharge-pipe connecting with the cylinder and extending through the boiler-shell, and two siphon-pipes connecting with the escape-pipe near its point of attachment with the said cylinder, said pipes extendingaround the fire-box and into the mud-ring, the lower end of each of the pipes being bent so as to extend within the mud-ring and perforated in the bent portions.

In testimony whereof I affix my signatu rein the presence of two witnesses.
