Superior Engines?

I am looking for information on a company that put out marine engines toward the end of WWII. Superior Engines only put out 8 engines in the history of the company, or so I am told- and then nothing. I can't find who they were bought out by, I am having a hard time finding someone who recognizes the name if the company, and I am at my witts end. Anyone out there with a little old school knowledge care to shed a little light for me? Thanks, Penny Walton

I've heard of that name engine being used in tugboats and other large marine applications. There should be a lot of info out there.

Hey Penny , try googling White -Superior . Large frame engines are used in the natural gas industry for compression duties and it's possible that Superior was merged with White . It's worth a try .

Hi Penny-
I have some leftovers from the Otto-Superior plant in North East Philadelphia. Mostly only Otto side of the business stuff. I have two WWII two cylinder Superior vertical diesels 4 1/4" bore on dc generators. Emergency generators for Navy ships. White Motor bought National Supply in the late 1940's. Most of the Ohio based Superior records were dumpstered :eek:in the early 1970's. I ended up with Otto in the early 1970's. The Superior side of the business records and parts were probably sent back to Springfield Ohio from Philly about 1949 or so. They may have made 8 different sizes of engines. The ones you ask about were verticals, 2,4, 6, or 8 cylinder variations of the same series engines. I can confirm at least two different series of engines, there may have been 8. I can't say. :shrug: Most of the smaller Superior Marine Diesels were made at the Holmesburg (Philly) plant that was sold off about 1949. The big Superiors continued to be made in Springfield and I suspect that the small marine diesels were discontinued about that time. I don't know much about the Superior side of the business but will try to help.:wave:
Thank you,

Penny,
I worked on a small 300 foot tanker with two in-line 6 cylinder Superior direct reversing diesel engines of 1050 hp each on the Great Lakes(Michigan, Erie & Ontario) around 1970, '71. Later it was relocated to the east coast based in NYC.
As I recall the individual cylinder heads weighed about 450 to 500 lbs. Exhaust valves were in separate cages & caused considerable trouble. The bores were around 20" in diameter & engines ran about 300 rpm if I'm remembering correctly. I'm sure more than 8 of these engines were built.

Well it looks like I'm kind of late chimming in on this topic, 2 of the larger engines made by Superior were the 40-SX-8, and the 60-SX-8, these were huge slow moving industrial engines, great engines, but nobody wanted them, so they were scrapped:( I still have 2 cranks and a muffler for yard art

Buried here somewhere is some Superior literature re' engines in a WWII LST or something similar, but I don't recall if they were the main propulsion engines or auxiliary power units.
A 1956 Fed Mog bearing catalog lists a 1cyl, three 2cyl's, 7 4cyl's, 13 6cyls and 11 8cyl's, ranging from 51/2x7 to 81/2x101/2, which would be their smaller industrial diesels. This type of catalog wouldn't show any heavier marine engines.

I have a 10 HP Superior vertical 2 cyl engine. Data plate Info. National Supply Co, Springfield Ohio

It is on a marine display trailer and it runs a 36 inch 3 blade bronze prop at low rpm"s. Don't know if the info will help you.

The 1917 National Supply Catalog states about Superior engines, "The simplicity, strength and staying qualities of these engines are unquestioned, and the fact that they have been in continuous use for more than 20 years is a high tribute to their quality."
P. J. Shouvlin on Washington St. in Springfield, Ohio renamed his machine shop in the 1890s to The Superior Engine Company. His first oilfield pumping engine was sold to a company in Findlay, Ohio which became the Ohio Oil Company and then Marathon Oil.
By its 25th anniversary in 1914 Superior was selling a line of standard engines from 20 to 100 horsepower, tank cooled and open jacket engines from 2.5 to 15 horsepower, both stationary and mounted on all-steel trucks, throughout the country.
In 1928 Superior was acquired by the National Supply Company with P. J. Shouvlin as head of the Superior Engine Division. In 1930 Superior diesels were applied for the first time to rotary drilling.
The Superior Engine Division ended 1942 by receiving the maritime Commission "M" award and Victory Fleet flag for its record of building diesel engines for U.S. Liberty Ships. Superior also built engines for National LST landing-craft vessels and for lend-lease to other Allied nations.
By the mid 1950s the division's engines were being used in practically every petroleum-producing area of the world. In April 1955 National Supply Company sold its Diesel Division to White when the Springfield facility became the White Diesel Engine Division. Several years later National Supply was acquired by Armco Steel Corporation of Middletown, Ohio.
Superior engines were used by the U.S. Department of Defense as power generating equipment for SAGE, DEW line radar, Bomarc, Atlas, Nike-Zeus, Nike-Hercules, Mace and Titan II missiles. In total, White Superior Division diesel engine-generator sets provided power for more than 175 missile sites and 18 major defense programs. The Bell System installed Superior sets for precise electric power to control, compute and track its Telstar communications satellite. The division withdrew completely from marine diesel production when it was purchased by Cooper.

In 1946 Ingalls shipbuilding attempted to enter the Diesel locomotive market with a locomotive powered by a 1500 hp Superior. It was in service until 1960, the only one ever built, with the GM&O.

Superior gensets were supplied to the U.S. navy and installed in LST and Patrol Chasers. LST main engines were all EMD 567 series V12 while generators were 3x3cyl Cleveland division built engines or three straight 8 Superior engine of about 300 hp. I don't recall the model of these engines but they were very sweet runners. regards ray
