' SPECIFICATION forming part f Letters Patent No. 689,742, dated December 24, 1901.

Application filed July 3, 1901. Serial No. 67,055. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM NEWMAN, a citizen of the United States, residing at Alexandria, in the county of Hanson and State of South Dakota, have made certain new and useful Improvements in Tools, of which the following is a specification.

My invention is an improvement in devices for removing fines from boilers, and has for an object to provide a device simple in construction, easily operated, and by which the flue may be driven or punched from the flue sheet of the boiler; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side view of my invention {as in use, the flue-sheet and flue being shown in section. Fig. 2 is a 1ongitndinal section of the device, partly broken away; and Fig. 3 illustrates the parts detached.

My invention is a device for removing fines from'boilers, as will be understood from Fig. 1, wherein the flue-sheet A and the fine B are shown in section, the bead on the flue having been cut off level with the fine-sheet, so the tool may be operated as a ram or punch to punch out the fine.

The tool comprises the main bar, which has a handle 0, which should be as long or a lit: tle longer than the flue to be removed, and the bar also has a shoulderD and beyond the same a shank or tang E, abouttwo feet long, the end of which is' threaded or otherwise adapted to receive a securing device, which may be a nut F or other suitable device, for

retaining the tapered guide when such guide is made removable, as shown in the drawings. The tool also comprises a cutter G, which forms a shoulder or ring to abut the end of the flue, and this driving-shoulder G is preferably of tool-steel tempered with both edges sharp, so it can be reversed if one edge becomes dull or broken.

In operation the drivingshonlder or ring G is fitted on the shank E up against the shoulder D, which forms a firm support for it. The

tapered guide or cone H is now slipped over the tang with its larger end foremost, up against the driving shoulder or ring, and is then secured by the nut F, as shown. The

cone forms the tapered guide and has its larger end adjacentto the driving shoulder or ring formed to fit in the flue, so it Will guide the shoulder or ringin operation against the end of the line, so it can operate as a ram for driving the same as may be desired. The

driving shoulder or ring is of a diameter not exceeding the external diameter of the fine and is preferably made of the same or about the same diameter as the fine, so it will operate squarely against the end of the fine and may pass through the flue-openings in the flue-sheet of the boiler.

In operation the tapered guide and the drive shoulder or ring may be removed and others substituted to fit tubes of dilferent sizes, and

for this reason it is preferred to make the tapered guide and the driving shoulder or ring separate from the main bar of the device and removable, as described, as well as for the further reason that it enables me to so construct the device that the operating parts may be made of material suited for the purpose and that the wearing parts may be readily replaced Whenever desired.

The tapered form of the guide-cone facilitates the introduction of the device into the fine and the operation of the device as a ram by guiding the driving shoulder or ring accurately against the end of the flue.

It will be understood that the same main bar can be used for all sizes of fines by having guide cones or rings fitted to the diiferent fines. In practice I find it desirable to make the main bar of machine-steel about one and aneighth inches in diametenthe cones ofcast-iron, and the cutter-rings of tool-steel. Where desired,the main bar may be'jointed "for convenience in transportation and storas described, comprising the handle bar or rod a driving shoulder or ring whose diameter does not exceed the external diameter of the flue to be removed, and the tapered guide or cone extending beyond the driving shoulder or ring on the opposite side of the driving-shoulder from the handle-bar and adapted to operate in the flue, substantially as set forth.

3. A tool for use in removing lines from flue-sheets, comprising the main bar, and a separate detachable driving-ring and tapered guide thereon, substantially as set forth.

4. A tool for removing fines from fluesheets, comprising the main bar havingahandle, the guide-tube and the driving ring or cutter held on said main bar and between the 6. The tool herein described, comprising the main bar having a shoulder and a tang or shank beyond the same, and the cutter-ring, and guide-tube on the same tang beyond the shoulder of the main bar, substantially as set forth.

7. The tool herein described, comprising the main bar having a stop-shoulder and the shank or tang beyond the same, the driving shoulder or ring fitted on said tang up against the shoulder, and of a diameter not exceed ing that of the flue to be removed, and the tapered guide-tube fitting on the tang up against the driving shoulder or ring, with its larger end next the said ring, and of a diameter to fit the fine to be removed, substantially as set forth.

WILLIAM NEWMAN.
