JOHN DVEORA, OF TOWER HILL, ILLINOIS.

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 552,406, dated December 31, 1895.

Application filed August 28, 1895.

T0 aZZ whom it may concern.-

Be it known that 1, JOHN DVEORA, a citizen of the United States, residing at Tower Hill, in the county of'Shelby, State of Illinois, have invented certain new and useful Improvements in Boiler- Cleaners; I and I do hereby declare the following to be afull, 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.

My invention relates to improvements in de vices for blowing off the sediment in boilers.

The invention will first be described in connection with the accompanying drawin gs,and then particularly pointed out in the claims.

In the drawings, Figure 1 is a longitudinal central vertical section, partly in elevation, of a boiler provided with my improved device. Fig. 2 is a detail front view, partly in section, of the same. Fig. 3 is a detail view.

Referring to the drawings, A is a boilershell which may be of any usual construction, in the bottom of which is placed a false bottom B, comprising two wings or deflectors b, and a centrally-arranged trough or conveyerbox I). In the latter is placed a spiral conveyer 0, provided with a shaft 0, which is j ournaled at each end in boxes 0, fixed inside the boiler-shell. On the conveyer-shaft c is fixed a bevel gear-wheel D,which meshes into a corresponding bevel gear-wheel D, secured on the end of the vertical shaft E, which projects through the bottom of the boiler-shell and is held by a bearing e, riveted to the boilcr-shell,the bearing havingapacking-ring e and a gland (2 the latter threaded onto the bearing,whereby all leakage around the shaft is prevented.

On the shaft E is fixed a second bevel gearwheel D which meshes into a corresponding bevel gear-wheel D fixed on the shaft f, of a motor-wheel F, which is provided with suitable buckles or vanes f.

The vertical shaft E and the motor-shaft f are carried by a hanger G attached to the under side of the boiler and provided with three bearings g g 9 the first two, g g, carrying the vertical shaft, the latter bearing, g supporting one end of the motor-shaftfiwhose other end is held by a casing II, which is secured to the boiler-shell and surrounds the motor, the vertical shaft, its attached gear- Serial No. 560,745. (No model.)

wheel D and the gear-wheel D The casing H is provided with an outlet h and with an inlet-pipe h, having a valve b and serving to convey water and steam from the boiler to the 1n otor-wheel, the said inlet-pipe also serving as a blow-off pipe for the boiler, and be ing arranged at one end of the screw or conveyer and tangential to the motor-wheel.

In order to hold the vertical shaft E against longitudinal movement it is provided with collars i, as shown.

The operation of my device may be briefly described as follows: When it is desired to blow off the sediment from the boiler, the valve 71 is opened, whereupon the escaping water and steam strikes the buckets of the motor and rotates the same, thereby rotating the conveyer or screw through the medium of the gearing. The rotation of the screw draws the sediment which settles in the trough of the false bottom B toward the blow-off pipe h, where it is forced out, passing the motor-wheel and escaping with the mingled water and steam at the outlet h. Furthermore, the rotation of the screw agitates the water and washes loose the sediment on the deflectors or wings b, which is thereby carried to the conveyer-trough and fin ally forced out through the blow-off pipe. By this construction all the sediment is carried off from the boiler with a minimum waste of water.

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

1. The combination, with a boiler, of a conveyer device located at the bottom of the boiler, a blow-off pipe located near one end of the conveyer, and a motor located beneath the blow-off pipe, said motor being arranged to be driven by the fluid escaping through the blow-off, and serving to drive the conveyer, substantially as and for the purpose described.

2. The combination,with a boiler, of a false bottom located in the boiler and having a trough portion, a conveyer located in the trough, a blow-off pipe at the end of the conveyer, a motor beneath the blow-off pipe and arranged to be driven by the fluid escaping through the pipe, and means for transmitting motion from the motor to the conveyer, substantially as and for the purpose described.

3. The combination,with a boiler, of a false bottom located in the boiler and having a trough portion and a deflector at each side of the trough, a conveyer located in the trough, a blow-oif pipe at the end of the conveyer, a motor beneath the blow-01f pipe and arranged to be driven by the fluid escaping through said pipe, and means for transmitting motion from the motor to the conveyor, substantially as described.

4. The combination, with a boiler, a conveyer located within the boiler and provided with a shaft, a pair of journal boxes secured within the boiler and supporting the conveyer shaft, a vertical shaft having one end projecting into the boiler, a bearing provided with a packing device through which the vertical shaft passes, means for transmitting motion from the vertical shaft to the conveyer shaft, a blow-oif pipe at the end of the conveyer, and a motor arranged to be driven by the fluid escaping from the blow-off pipe, and transmitting motion to the vertical shaft, substantially as and for the purpose described.

5. The combination, with a boiler, a conveyer located at the bottom of the boiler, a blow-01f pipe at the end of the conveyer, and a motor arranged beneath the blow-oil pipe and adapted to be driven by the fluid escaping therefrom, of a valve in the blow-off pipe, mechanism for transmitting motion from the motor to the conveyor, and a casing surrounding said mechanism and the motor, and provided with an outlet, all operatively arranged as and for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.
