Description
UNITED STATES yPATENT OEEroEg WILLIAM ORD, OF BROOKLYN, OHIO.
vIMPROVEMENT IN CIRQULATING DEVICES FOR STEAM-BOILERS.
Specification forming part of Letters Patent No. 186,493, dated January 23, 1877 application tiled October 23, 1876.
To all whom it may concern:
Be it known that I, WILLIAM OED, of Brooklyn, in the county of Cuyahoga and State of Ohio, have inventeda new and Improved Steam-Boiler, of which the following is a speciiicatiou:
In the accompanying drawing, Figure 1 represents a side elevation of my improved steam-boiler. Fig. 2 is a vertical transverse section of the same on line .r an, Fig. 1; and Fig. 3 is a rear elevation of the same. a y Similar letters of reference indicate corresponding parts.
The inventionyrelates to improvements in stea1n-boilers, by which the boiler is kept in ei'ective manner free from mud and sediment, preventing the mud from settling at the rear end, and carrying the same forward to be deposited iny a mud-drum at the front part of the boiler, where suitable means are provided for washing out the sediment.
The invention consists of a boiler with a downward-extending water-leg, arranged at both sides of the iirebox at the front end of the boiler, the water-leg being connected by rear cylinders and a series ofrconducting-tubes to the rear end of the boilern The water-leg communicates by bottom holes, and by side holes near the corner or upper part of the leg, with the boiler.
In the drawing, A represents a tubular or other steam-boiler, which is provided With a Water-leg, B, that extends downward at the front end of the boiler, at both sides of the ire-box, for the purpose of serving as fire- 'front and 1nud-ehamber, the usual mud-drum being dispensed with. The boiler communi- Gates by bottom openings a with the waterleg, and also by side openings b, near the upper part or corner of the water-leg, where the same is attached to the sides of the boiler.
From both sections of the water-leg B ex tend in backward direction cylindrical tubes C, thatare arranged at suitable height above the lowermost part of the water-leg, so that l the parts below the cylinders or foot serve as'` mud-chamber `for collecting the sediments.
The `cylindrical tubes G connect by a series of conducting-pipes, D, with the rear end of the boiler, as shown in Fig. 1, the pipes D- forms the subject-matter of a separate application heretofore filed by me.
'The water in the water-leg is heated up therein, and the steam generated will find an outlet to boiler at the upper corner on each side. The water descending next to the outside of the water-leg is cooler'than that del scending at l the inside next to the fire. The' cooler waterpasses down and through extension-cylinders O intoithe conducting-pipes D, which are in directcontact with the fire that heats`the water therein, so that it ascends and enters at the rear end of the boiler, producing a forward current of water, that acts along the whole length of boiler, and carries the mud or sediments to the outlet at the foot of water-leg, preventing the mud from settling at the rear end. The mud is deposited in the mud-chamber at the foot of water-leg, and blown `out by suitable means, in the customary manner. y
Having thus described myinvention, I claim as new and desire-to secure by Letters Pat-M ent- The combination, with boiler A, of the water legs B B, below and out of contact with the fire-box, but connected with the frontl of boiler by holes a., and with the rear thereof by tubes C D D', as shown and described,
whereby that portion of legs B below the tubes O is made to serve the purpose of lnuddrums, while a constant current is forced longitudinally through the boiler. A
