A. BERNEY. Inserting Tubes in Boilers.
No. 239,019. Patented March 22,1881.

UNITED STATES PATENT OFFICE.
ALFRED BERNEY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO NATHIEL A. DUTTON, OF SAME PLACE.
INSERTING TUBES IN BOILERS.
SPECIFICATION formingpart of Letters Patent No. 239,019, dated March 22, 1881. Application filed October 9, 1879.
To all whom it may concern:
Be it known that I,=ALFRED BERNEY, of the city of Boston, county of Suffolk, and State of Massachusetts, have invented a new and useful Improvement in Inserting Tubes or Flues in Boilers, of which the following is a specification.
The invention relates to inserting larger tubes in boilers in place of smaller ones, and
is especially applicable to locomotives, Where it is necessary to apply larger tubes to carry the sparks, cinders, and dirt back into the firebox through the boiler to be consumed.
Heretofore where the mechanics could not find a blank place in the tube-sheets large enough to insert a three-inch tube, the sparkconsumer has been dispensed with, as it is impossible to put a patch upon the fluesheets.
' In other cases a patch might be riveted on;
but my method is the simplest, neatest, and quickest, and a long series of tests, even to removing the large flues after they have been in service for a time and inserting new ones has proved it safe, as no leaks have occurred 2:, around the large tubes or disks, and the disks are as firm as the original flue-sheet.
In carrying out my invention remove the old lines, where desired, tap the fine-holes with a suitable-sized screw-thread, and turn a piece ofround iron slightly tapering, cutting a corresponding thread on it to [it the hole tightly. After fitting it 1 mark it so as to cut it nearly 01-1 in a lathe, then screw it in the hole and cut or break ott' the plug. I fill as many tube-holes as are necessary, care being taken not to have the plugs thicker than the flue-sheet. I then mark out the hole required, using judgment and care, so as to leave a little over half of the plug in the holes, which any skillful boiler- 40 maker can do. I then drill out the large hole and insert the flue in the usual manner.
In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is an elevation of a device embody- 5 ing myinvention. Fig. 2 is a cross-section of the same. Fig. 3 is a longitudinal section. Fig. 4. is a detail section, showing a plug.
In the heads of the boiler A, are flue or tube holes closed up with plugs O, or parts of plugs E partly drilled out, and the large tubes D inserted. As will be seen at W, one tube, is Wholly to be removed, which can be done by plugging, then centering and drilling all the plug and part of the flue-sheet. At X a portion of one disk or plug is drilled out with more of the tube-sheet. At Y two tubes are necessary to be taken out and theholes plugged and the larger hole drilled. At Z three tubes are removed, centering so as to drill out part of three plugs.
Four tubes can be removed plugged and bored out to insert a large tube 1t necessary, care being taken to drill out in the center between the t'our plugs, as described heretofore.
A metallic ring or bushing can be inserted in the large tube-holes over the disks to keep them in place, and l have used them for that purpose, although they will remain in without the rings, even after years of use. Where it would be impossible to allow one -half of a plug to remain, a bushing Would be much the best. I prefer copper rings for this purpose.
The disks E can be kept from moving while being bored, or on removing the large tubes when Worn out, byiuserting between the edge 7 of the plug and flue-sheet, at the part where theyjoin, a screw, pin, or plug, as seen in dotted lines on the drawings, around the disks of tube Z, yet the disks E do remain solid without them.
, Havingdescribed my invention, what claim as new, and desire to secure by Letters Patout, is,-
The method herein described for inserting tubes of larger diameter in tube-sheets, con- 85 sisting in first removing the small tubes and plugging up the old holes, then boring out the larger ones, and finally inserting and securing the tubes therein, substantially as herein specified, and for the purposes set forth.
ALFRED BERNEY.
