REPORT OF THE CHIEF INSPECTOR, BUREAU OF LOCOMOTIVE IN- SPECTION, COVERING INVESTIGATION OF ACCIDENT TO CHICAGO, ROCK ISLAND & PACIFIC RAILWAY LOCOMOTIVE 2132, WHICH OCCURRED NEAR HARRAH, OKLA., JULY 3, 1923. Washington, August 14, 1923. To the Interstate Commerce Commission: Chicago, Rock Island & Pacific Railway locomotive 2132 was dispatched from Shawnee, Okla., at 6 a. m. on July 3, 1923, in freight service, and when at a point about 2 miles west of Harrah, Okla., or 20 miles from Shawnee, and while running at an estimated speed of 20 miles per hour, a flue pocket blew out of the front flue sheet, when the escaping steam and water from the boiler caused the flames and fire-box gases to be blown back into the cab, resulting in the serious injury of Engineer R. W. Lamon and Fireman G. Q. Jones. This locomotive was turned out of the Shawnee shops of this car- rier on July 1, or two days prior to the accident, after having re- ceived class 3 repairs, and was at the time of the accident making its first regular trip in freight service since receiving repairs. During the repairs all flues were renewed and 40 flue pockets, which had been previously applied, were renewed and 8 additional flue pockets were applied, making a total of 48 flue pockets applied in the front flue sheet for the purpose of closing holes from which flues had been removed when changes in the fire-box flue sheet were made. EXAMINATION OF FLUE POCKET. Examination disclosed that neither the flue pocket which blew out, as illustrated in Figure 1, nor any of the others had been prossered, but were only held in place by friction. The flue pockets were applied by Boilermaker Helper R. R. Luper and were inspected by Boiler Inspector J. Clark, who signed and swore to annual locomotive inspection and repair report, dated July 1, 1923, showing that all flues were in good condition, and the report approved by General Foreman A. Hambleton, as officer in charge. Inspections and repairs at Shawnee are under the general super- vision and direction of Mr. L. D. Richards, master mechanic. 1 INTERSTATE COMMERCE COMMISSION REPORTS. Our examination of locomotives Nos. 2120, 2135, 2139, and 2144 disclosed that in each of the front flue sheets there were 48 flue pock- ets which had not been prossered, or means provided to secure them in place, other than friction. The carrier's records show that all of these locomotives received new flues and flue pockets during the period January to April, 1923. ACCIDENT NEAR HARRAH, OKLA. 3 Figure 1 shows the flue pocket as applied and held only by fric- tion, while Figure 2 shows the manner in which the flue pocket should have been prossered or enlarged inside of flue sheet, which would have prevented' it from blowing out. The necessity for properly prossering or enlarging flue pockets inside the sheet is so well recognized by mechanics that comment hardly seems necessary. The workmen who did this work and the supervising officials in charge who permitted it can not be too strongly censured for such careless and indifferent methods, which show an extreme disregard for safety on their part. The Bureau of Locomotive Inspection has seriously objected since its inauguration to flue pockets being applied in the fire-box flue sheet because of unsafe conditions created. It has not, however, objected to flue pockets applied in reasonable number in the front flue sheet when properly belled and prossered, but we do not approve as being proper and safe practice of applying the number of flue pockets which were found in this instance, for the reason that it leaves a large unsupported area and throws an undue strain on the remaining adjacent flues. Kespectfully, A. G. Pack, Chief Inspector. o Digitized by the Internet Archive in 2012 with funding from University of Florida, George A.
