Description

I "UNITED ST ES PATENT OFFICE.
JAMES E. HENRY, on ASHLAND, WISCONSIN.
FLUE-BLOW -OUT DEVICE FOR BOILERS. i
' an improved steam blow-out device for cleaning boiler fines, and to this endit conslsts oi the novelde'vices and combinations of devices hereinafter described and defined in the claims.
In the accompanying drawings which illustrate the invention, like characters indicate llke parts throughout the several views.
Referring to the drawings, Figure -1 is a view partly'in'side elevation and partly in vertical section, showing my improved 1) out device applied in working position, some parts being broken away; and Fig. 2 is a transverse vertical section taken approximately on the line m m of Fig. 1.
The numeral 1 indicates a horizontal boiler having the usual lines 2; and the numeral 3 indicates the rear wall of the boiler setting.
In the upper portion of the wall 3 is a bearing sleeve 4, and working vertically through this bearing sleeve is a steani'pipe 5 which, at its lower end, is provided with a horizontally extended nozzle pipe (3. The nozzle p pe 6 is provided with a plurality of forwardly turned, disr'zharge nozzles 7 that are located one in the vertical plane of each vertical row of llues 2 and terminate quite close to the adjacent ends of said llues. The steam pi )e 5 .works vertically through the lower en head bracket 8 of a yoke-like frame. .I, the vertical prongs of which are parallel to each other. To the up )0! end of the pipe 5 is secured a-guide hem 10 that is mounted to slide upon the parallel prongs or legs of p the 'lr ame 9.
Ilmosely journaled in the upper-portion of the l'rame 9 is a small Windlass drum 11 that is provided with. a ratchet wheel 12, and to the shaft of which is secured an o crating crank 13. On the drum 11 is woun a cable Specification of Letters Patent.
Application filed May 18, 1908. Serial No. 317,569-
in presence of two ratented May 14, 1907.
14, the lower'end of which is attached to the upper end of the vertically movable steam pipe 5. A retainin pawl '15. which as shown, is pivoted on t e upper portion oi the frame 9, acts upon the ratchet wheel 12 to prevent rotation of the drum 11 under the weight of the-pipe 5 and arts carried thereby.
For the urpose of b owing out the flues, steam wou d usually be conveyed from the boiler 1 to the vertically-movable steam pli pe 5 through a flexible pipe or hose 16; or the purpose of indieatin with which horizontal row of fines the nozz e pipefi is vertically alined, the sliding head 10 is 'rovided with a pointer 17, and the ad'acent Peg of the frame 9 is provided with mar s 18.
As is evident, the nozzle ipe 6 may be ver ticall adjusted, at will, y means of the wind ass and crank, and thereby brought into such position that its nozzle 7 will be alined with the flues of any horizontal row. Thus, simple and efficient means is afforded for rendering the flue blow-out device operative without entering or opening up the fire-box or combustion chamber. It is, therefore, possible to blow out the lines without extinguishing the fire and, hence, without loss of time or interruption in the use of the boiler. Furthermore, the device simple and of snlall cost.
' What I claim is:
The combination with a boiler 1 havin nos 2, and a wall 3 joining one end of sai boiler, of. a steam pipe 5 working vertically.
through said wall 3 and provided, at its lower end, with a nozzle pipe 6 having nozzle's'7 adapted to aline with any of the-horizontal rows of said lines, a relativelyfixed rectan-.
gular frame 9, throu h a portion of which said pipe-5 is mounted to side, a Windlass on the upper portion of said frame, a cable connecting said Windlass to said pipe 5' for mov ing the same vertically, and means for lock-.
ing said Windlass against rotation to support said pipe 5 and nozzle pipe 6 in dillerent vertical positions, substantiallyias described.
In testimony whereof I ailix my signature witnesses:
