DALE BREED, OF 'TIOONDEROGA, NEW YORK.
BOILER-CLEANING- APPARATUS.
To all whom, it may concern:
Be it known that I, DALE L. BREED, a citizen of the United States, residing. at Ticondero a, in the county of Essex'and State ork, have invented a new and useful Boiler-Cleaning Apparatus, of which the following is a specification.
This invention is an apparatus for re moving scale or incrustation from steam boiler drums or other cylindrical vessels.
Heretofore, when it has been desired to remove scaleor other incrustation from the interior of a steam boiler drum or other similarcylindrical vessel, it has been customary to have workmen enter the vessel for the purpose of removing the foreign substances by the use of hand-operated tools, a method which is very costly, slow, dangerous to the health of the workmen, and more or less unsatisfactory. One of the objects of theinvention is to overcome the disadvantages of the hand method by providing an apparatus capable of removing the scale or incrustation by mechanical means. A further object is to provide an. apparatus of simple and inexpensive construction which may be readily placed into and removed from operative position. I
The invention will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying drawing Figure 1 is a longitudinal sectional view illustrating a boiler drum in which is positioned a scale-removing apparatus con structed in accordance with the invention. Fig. 2 is a transverse sectional view illustrating the tool support. Fig. 3 is a side view illustrating one of the bridge bearings. Fig. 4 is a similar view illustrating an extension bearing.
Referring to the drawings, 10 designates a portion of a cylindrical-casing, which may be steam boiler drum or any other cylindrical vessel, the invention not being limited in this particular. Located at the ends of the casing and within the same, are bearings 11, each provided at its ends with lateral extensions 12 concentric with the wall of the easing 10, and securely retained in position by screws 13 working in said extensions and bearing against .said casing wall. Each bearing is also provided with a removable section 14 to permit the cleaner to be in serted, into and removed from operative 'position,
V Specification of Letters Patent. Patented J an, 11, 1921, Application filed June 13, 1919. Serial No. I
Rotatably mounted in the bridge bearings 11, is a main tubular shaft 15, which is slotted longitudinally, as indicated at 16, and rotatably mounted within the shaft 15 is a feed screw 17. Operatively engaging the screw 17 is a hub 18 located within the shaft 15 and of a shape to travel therethrough, said hub being provided with a-radial arm 19 extending through the slot 16.. Slidably mounted on the arm 19 is an extension arm 20, provided at its free end-with suitable means, such as a bracket 21,v for engaging and supporting a motor 22, for driving the abrading member 23, which may be a toothed bur, cutter, or other tool suitable for the work requirements. The motor 22 may be of any desired or suitable type driven by steam, air, electricity, or any other desired power. In the drawing an electrio'motor is conventionally illustrated, the feed wires 20 of which are of the usual and well-known flexible type. Said wires lead to the outside of the boiler through the man-hole 27 passing around the bearing 26, to any suitable source of supply and any desired form of control device (not shown). The extension arm 20 is free to slide upon the arm 19, but rotation thereof is prevented in any preferred manner, for instance, by means of a pin 24 engaging complemental slots 25.
Mounted in an extension bearing 26, located in the manhole 27, is an extension tube 28 which is removably interlocked with the shaft 15 inv suitable manner, a pin and slot connection 29, being illustrated. It will be noted that the bearing 26 is a substantial duplicat'e of the bridge bearing 11, but of smaller dimensions. Inside of the extension tube 28 is placed a driving shaft 30, provided with meansfor engaging the outer end of the feed screw 17, such means, in the form illustrated, consisting of a socket 31 shaped to engage a squared end of the feed screw. Said driving shaft is mounted in suitable bearings 32 within the extension tube, and is provided with a hand crank 33, whereby it may be rotated. The extension tube 28 is provided with an arm 34 by which it also may be rotated.
In practice, when it is desired to clean the interior of a boiler drum or other similar vessel, the bridge bearings 11 are placed in position, and the slotted shaft 15 carry ing the feed screw 17, is then placed in position, the arm 19 projecting radially through the slot 16. The extension arm is then engaged with the arm 19, thereby ositioning the motor 22 and abrading mem er 23 in operative position. The extension bearing 25 is then placed in position inthe manhole, and the extension tube 28 and driving shaft 30 brought into engagement with the slotted shaft 15 and the feed screw 17, the collars 35 being adjusted to retain the extension tube in proper position. Power is then applied to the motor 22, and by rotating the shaft 15 through the medium of the arm 34 the abrading member 23 is caused to travel over the area to be cleaned, said member rotating all of the time, and at the same time the feed screw 17 is operated through the medium of the hand crank 33 to cause the member 23 to travel lengthwise of the casing 10. By providing a slidable connection between the arm 19 and extension arm 20, the cutter is permitted to adjust itself to overcome any inaccuracy in the original setting of the shaft 15 and also to conform to any unevenness of the inner surface of casing 10. In this manner, all scale or incrustation may be rapidly and economically removed from the entire inner surface of the drum without it being necessary for the operator to enter the vessel during the cleaning process.
Having thus explained the nature-of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the forms of its use, what is claimed is 1. A boiler cleaning apparatus of the character described comprising a rotatable shaft, an abrading member carried by said shaft and mounted to travel in an orbit around the latter, means for causing the abrading member to travel in a line parallel with sa1d shaft, and means for imparting rotations to said abrading member independently of the rotations of said shaft.
2.

ber longitudinally of the shaft.
3. A boiler cleaning apparatus of the character described comprising a rotatable shaft, an arm extending radially from said shaft and rotatable therewith, an abrasive member adjustably supported by said arm, means for feeding said abrasive member longitudinally of said shaft, and means for actuating said abrasive member independently of the rotation of said shaft.
4.
