llillED %CFATE PATENT FREDERICK V7. LINAKER, 0F DUBOIS, PENNSYLVANIA, ASSIGNOB TO THE VULCAN SOOT CLEANER 00., 0F PITTSBURG, PA., 01" DUBOIS, PENNSYLVANIA, A CORPORA- TION OF NEW JERSEY.

SOOT-CLEANER FOB, WATER-TUBE BOILERS.

Application filed November 13, 1915.

To all whom it may concern:

it known that I, FREDERICK W. LIN- AKEK, a subject of the King of England, residing at Dubois, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Soot-Cleaners for VVater-Tube Boilers, of which the following is a specification.

This invention relates to certain new and useful improvements in soot cleaners for water tube boilers.

In water tube boilers of the Stirling type including vertical and semi-vertical water tubes with battles arranged adjacent the tubes, it has been customary to position the cleaning fluid distributing pipe adjacent the tubes and the outer end of the bafile and during the cleaning operation, the jets of cleaning fluid are directed over the tubes and toward the fire-box. t will be readily seen that the discharged cleaning fluid while passing in a direction toward the fire-box will act as a damper for the gases and products of combustion andblow the same back into the fire-box and through the fire door and front of the furnace which might cause serious injury to the-operator. The present invention, therefore, aims to overcome this defect by a particular construction of cleaning fluid distributing pipe which when in operation, will have jets of cleaning fluid issuing from a plurality of series of jet nozzles or discharge ports that are disposed in different radial planes with respect to the axis of the distributing pipe. It will be seen that when a jet of cleaning fluid is directed over the tubes and toward the fire box, that the blowing and damper effect thereof will be overcome by a jet of cleaning fluid blowing in a different direction and the gases and products of combustion may freely pass over the tubes and reach the outlet stack withoutbeing blown back into the fire-box.

With these general objects in View and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more Specification of Letters Patent.

Serial No. 61,359.

present invention in operative position therein.

Fig. 2 1s a sectional view of a portlon of the same illustrating a portion of the battle wall, water tubes and the cleaning fluid distributing pipe.

Fig. 3 is a cross-sectional view of another construction of water tube boiler of the Stirling type'with the present invention in operative position therein, and,

Fig. l is a view of a plurality of cleaning fluid distributime, pipes in which the jet noz- Zles are arranged in different series and in different radial planes about the pipe.

Referring more in detail to the accompanying drawings and particularly to Fig. 1, the reference numeral 10 designates a boiler setting including banks of tubes A, B and C. Baffies are associated with the banks of tubes and are designated 11, 12 and 13. The baffles 11 and 12 are associated with the bank of tubes A and are so positioned as to positively cause the gases and products of combustion to travel over the tubes A while the baffle 13 is so positioned as to cause the gases to engage the tubes B.

Cleaning fluid distributing pipes 14: are associated with each of the banks of tubes and are preferably of the rotary type, the same being operated by the chains 15 as in dicated in dotted lines in Fig. 1. The piping system for feeding the cleaning fluid agent to the distributing pipes 14 includes the main supply 16 communicating with the feed pipe 17 which in turn communicates with the branch pipes 18 and all of the pipes are valve controlled while a drain-cock is provided for the main supply as is indicated.

As shown in detail in Fig. 2, the dis tributing pipe 1 adjacent the balile 12 may be journaled in the side walls of the boiler setting 10, and has a swivel connection with the branch pipe 18 as is indicated. The distributing pipe 14: is further supported in termediate the ends thereof as by straps or stirrups 19 that engage certain ones of the Water tubes A and also support the pipe.

Thejet nozzles are positioned in series about the distributing pipe in different radial planes, and as shown in Fig. 2, the nozzles 20 are in longitudinal alinement on one side of the pipe and extend substantially halfiway thereof while the nozzles 21 are positioned on the opposite side of the pipe and are also in longitudinal alinement.

Different forms of the distributing pipe are shown in Fig. 4: and the pipe 14: has the jet nozzles 14: arranged in series of four each with each series alternating as is indicated. The pipe 14: has the jet nozzles 1 1 arranged in series of six each that alternate and are directed oppositely as is shown. The pipe 1 1 has the nozzles 14; arranged eight in each series with the nozzles o1 one series extending radially in one direction while the nozzles of the other series extend radially at right angles thereto and the pipe 14* has the jet nozzles 1-1 arranged 81K in each series, with the series in diiferent radial planes.

It is to be understood that the invention is not confined-to the use of jet nozzles as the pipe may be similarly provided with discharge ports and operate in a like manner without departing from the gist of the present invention.

A different type of boiler is shown in Fig. 3 and includes the setting 10 with the banks of tubes A, B and C while battles 22, 23, 24-, 25 and 26 are arranged adjacent the different banks of tubes and associated with each bank of tubes is a cleaning fluid distributing pipe M similar to the form shown in Fig. l and pipes that are also operated in a like manner. The distributing pipe 14 shown in Fig. 3 has a similar source of steam supply as is described in connection with the showing in Fig. 1.

In the operation of: the device, the cleaning fluid agent is fed to the distributing pipes 14 by the pipingsystem described and the distributing pipes subsequently revolved by the chains 15. The positioning of distributing nozzles about the periphery of the pipe will not in any manner cause the gases and products of combustion to be blown back into the fire-box and through the doors as the nozzles that are directed opposite to the ones that cause the jets of cleaning fluid to travel toward the fire-box will overcome any dampering effect that the same might have and will insure a proper circulation of the gases and products of combustion. It

is of course to be understood that the nozzles lat may be arranged in any desired manner in series and spaced in different radial planes about the periphery of the pipe. In boilers of this construction the gases and ,products of combustion are primarily retained by the first baflle to completely pass over the bank of tubes and with the dis tributing pipes positioned adjacent the ends of the baflies there is a tendency when a single stream or jet of cleaning fluid is directed toward the fire-box to force the gases and products of combustion back into the fire-box, but with the present invention, this difliculty is overcome and the gases and products of combustion have a free passage over the first bank of tubes and on to the other ones. The above detail description of the distributing pipes relates more particularly to those pipes that are slightly spaced from the battles as is indicated; but it is to be noted that the distributing pipes 14 that are arranged in close relation to the bafiles should preferably have the jet nozzles or outletports arranged in longitudinal aline ment.

WVhile the form oi" the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts'may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is A soot cleaner for boiler tubes, including a rotary distributing pipe associated with a bank of boiler tubes, the same being operable by hand-actuated means,:a main supply pipe communicating with a feed pipe, a branch pipe, all of said pipes being valve-controlled, said distributing pipe having a swivel connection with said branch pipe, and jet nozzles positioned in two series or sets about said distributing pipe in different radial planes, one set of said nozzles being in longitudinal alinement on one side of said pipe and extending about midway thereof and the second set of said nozzles being positioned also in longitudinal alinement along the other half of the distributing pipe and upon the opposite side of said pipe.

In testimony whereof I affiX my signature.

FREDERICK W. LINAKER.
