BOILER-CLEANER.

Specification of Letters Patent.

Application filed July 21, 1909.

Patented Feb. 22, 1910.

Serial No. 508,690.

To all whom it may concern:

Be it known that I, BENJAMIN F. PARKER, a citizen of the United States, residing at Murphysboro, in the county of Jackson and State of Illinois, have invented a new and useful Boiler-Cleaner, of which the following is a specification.

The object of this invention is to produce a very simple and eflicient device by the use of which the flues or tubes within a steam boiler may be thoroughly washed on all sides without the necessity of the operator going within the boiler.

The object is attained by the use of the device illustrated in the accompanying drawings, and the invention consists in certain novel features of the same, as will be hereinafter first fully described and then particularly pointed out in the appended claims.

In the accompanying drawings, which fully illustrate my invention Figure 1 is a transverse vertical section of a steam boiler having my improved cleaner in position therein. Fig. 2 is a detail perspective view of the device arranged to wash the upper and lower sides of the fiues or tubes. Fig. 3 is a detail perspective view of the device arranged to wash the sides of the fiues or tubes.

In carrying out my invention I employ a supply pipe 1, to which a hose may be attached, which is provided with a controlling valve 2, by whlch the flow of water, or other cleansing agent, may be controlled. The forward end of the supply-pipe 1 is turned down so as to provide a stirrup or supporting foot 3, which is adapted to travel over the bottom of the boiler in the operation of the device. At an intermediate point of the supporting foot, a coupling 4 projects laterally from the same and has an upturned end in which is secured a short vertical pipe 5, as clearly shown. In the arrangement of the device shown in Figs. 1 and 2, a vertical tube 6 is coupled to the u per end of the tube 5, and the upper end of the tube 6 is provided with a doubleended nozzle 7 by which the water is directed in both directions against the top and bot-- tom of the flues, as will be readily understood on reference to Fig. 1. The nozzle may be brought to a higher or lower plane, so as to direct the water between any desired rows of flues or tubes by means of a brace 8 having its opposite ends adjustably secured to the supply pipe 1 and the tube 6, as clearly shown. end of the brace 8 is attached to a sleeve 9 encircling the supply pipe 1 and secured to the same by a set screw 10 which secures the brace to the sleeve and the sleeve to the supply pipe at any desired point of the pipe to effect the proper adjustment. The upper forward end of the brace 8 is secured in a similar manner by a sleeve 11 and a set screw 12 to the tube 6. It will be readily seen that the brace 8 may be shifted along the supply pipe and also along the tube 6, and that when it is shifted along the supply pipe, the tube 6 will be swung forward or backward with the short connecting tube 5 which turns about the coupling 4: as a center, so that the nozzle 7 may be readily brought to work at the desired pointwithin the boiler.

In order to wash the vertical sides of the tubes, the straight tube 6 is disconnected from the short tube 5, and a pipe 13, having a bent end, is substituted for the tube 6, the said pipe having a nozzle M at its outer end, as clearly shown in Fig. 3. This bent pipe 13 may be adjusted relative to the supply pipe by means of the brace 8 in the same manner as the tube 6 is adjusted.

The operation of the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings. The end of the supply pipe, with its attached nozzle and adjusting brace, is inserted through the man-hole of the boiler, and the foot 3 is moved along the bottom of the shell of the boiler so as to carry the nozzle from one end to the other of the boiler. The water, steam or other cleaning agent being admitted through the pipe 1, will pass up through the short connecting tube 5 and the tube 6 or the pipe 13 to the nozzle from which it will escape with sufficient force to thoroughly remove from the tubes or flues all sediment collected thereon. It will be readily seen that the fluid escaping from the nozzle passes between adjacent rows of fines, and of course acts upon the opposed faces or surfaces of the said tubes or flues. The supply pipe 1 is preferably made of a length corresponding to the length of the boiler to be cleaned, so that the nozzle may be pushed to the far end of the boiler without any necessity of the operator entering the boiler at any time.

The device is extremely simple in its construction and can be readily adjusted so as The rear lower to bring the nozzle to any desired point, whereby all corners or surfaces of the boiler may be thoroughly cleaned whether they are remote from or near to the manhole.

The device may be used by an unskilled operator, and, when not in use, may be readily folded and placed away within small compass.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a supply pipe, of a nozzle, and a brace having its ends adjustably secured to the supply pipe and the nozzle.

2. The combination of a supply pipe having its end downturned to form a foot, a nozzle having a swiveled connection with the supply pipe, and an adjustable connection between the nozzle and the supply pipe.

3. The combination of a supply pipe, a nozzle having a swiveled connection with the supply pipe, sleeves adjustably mounted on the supply pipe and the nozzle, and a brace connecting the said sleeves.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

BENJAMIN F. PARKER.
