Columbian Rope Appoints Kirkpatrick James F. Kirkpatrick James F. Kirkpatrick has been appointed interplant manufacturing manager of Columbian Rope Com- pany, Auburn, N.Y., it was an- nounced by Frank R. Metcalf, president. Mr. Kirkpatrick moves to the home office of Columbian from the Plymouth, Mass. plant of Plymouth Cordage, a Columbian subsidiary, to assume his new duties. In making the announcement, Mr. Metcalf stated: "The creation of this new position, and the in- stallation of Jim Kirkpatrick in it, is a major step by Columbian to- ward increased efficiency in the manufacturing area." Mr. Kirkpatrick has been associ- ated with the textile and cordage industries for over 35 years. Prior to his present position, he served five years as interplant director of manufacturing for Plymouth Cord- age and has been associated with Columbian Rope and its subsidi- aries since 1941. Mr. Kirkpatrick is a graduate of Lafayette Univer- sity, holding a bachelor of science degree. Caterpillar Unveils New Marine Gears An extensive research and de- velopment program that began sev- eral years ago at Caterpillar Trac- tor Co. in Peoria, 111., has culmi- nated in the introduction of two new marine gears. The 7261 and 7241 join existing 7251 to form a family of marine gears matched to engines in the 550 to 1,200 horse- power range. The significant difference in the Caterpillar design is the use of planetary gearing, resulting in sav- ings in weight and size in compari- son to many other gears. The American Bureau of Shipping and Lloyds Register of Shipping have both approved the 7261 for 1,200 hp (a) 1,200 rpm, the 7251 for 900 hp @ 1.200 rpm, and the 7241 for 1,170 hp @ 1,800 rpm and 700 hp @ 1,200 rpm. Largest of the three gears, the 7261 is designed for the 1,125-hp D399 marine engine in ratios from 2.89:1 to 4.22:1 and deeper ratio requirements of the 8,510-hp D398. The 7241 is available in ratios rang- ing from 2.00:1 to 5.88:1 for the 565-hp D379, 725-hp D348 and 970- hp D349. The new family of gears repre- sents a continuing program at Caterpillar to develop dependable, compact marine gears to match a variety of applications from fishing to deepsea towing. Caterpillar first entered the marine gear market in the early fifties with the 3181, fol- lowed a few years later by the 3192 for larger, more powerful engines. The 3192 in turn was replaced by the improved 7251 gear in 1968. The 7251 is designed for all ratios behind the D379 and for shallow ratios behind the D398. Initial installations of the 7251 gear were closely monitored by Caterpillar engineering and service personnel to analyze their perform- ance and the effect of significant improvements made in design and construction over the former 3192 gear. Information and owner re- sponses gathered from these early 7251 applications have been incor- porated in the design and construc- tion of the new gears. With major design objectives of performance, long life and service- ability in mind, the basic planetary design of the field-proven 7251 was retained for the 7261 and 7241. This enabled Caterpillar, by draw- ing on its years of experience with planetary gearing, together with recent advances in technology, to develop a family of gears that of- fers significant benefits to marine users for a variety of applications. The crew that never went ashore. The ships that bring fresh air from Alaska. The time it got crowded in our first unmanned engine room. The punched tape that grew into a200000 tonner. rn These are some of the strange stories that can be told by people who build ships for a living.
