There are a number of companies that manufactured engines stationary and marine that appear to look just like or very similar to the DEW two cycle style engines produced back in the early 1900's. The information below will explain what some of the differences are on the engines manufactured or sold by DEW, DMCSC, CEC, MSBC, DBC, CPMC, MEC, BGEC, PIW.  

MSBC & DBC were boat manufactures that used other companies marine engines in their boats mostly DEW engines. MSBC retagged some of the DEW engines with their on MSBC tag.   It appears that DBC did not retag the DEW engines in their boats.

The stationary Middleditch & Bessemer engines have their own unique fuel feeder injector which bolts to the engine with a two hole type flange. The exhaust manifold is square box looking and bolts on with three or four studs. Heavy cast iron box style engine base with hinging door is also unique to the Middleditch & Bessemer engines. These are all differences that makes it easy to identify these two companies engines from the DEW style engines. I don't believe these two companies made two cycle marine engines at least I have never seen one.

 CPMC stationary engines also have unique features such as the tapered ends of the crank shaft with nuts used to hold the flywheels on . Most of the DEW style stationary engines used gib keys to secure the flywheels. Air intake & governor arm on the CPMC engines are cast different then DEW styles. (See photos CPMC section). These unique features make this companies engine easy to distinguish from other DEW style engines.

CPMC marine engines are a little more difficult to identify from the DEW style engine. Some of the Caille marine engines have tapered ends with nuts on the crank shaft and some do not. Advance & retard timer lever has square spring loaded ignition contact. I have never seen this on DEW style engines.

DEW or DMCSC marine engines that are missing the name tag are going to be difficult to figure out what factory the engine was manufactured in and the name tag that was put on the engine originally.  I'm currently starting to look at casting numbers as maybe away to identify the manufacture but have not figured anything out at this point. Over the years there were three different style inspection covers used on the Detroit marine engines. The first early style produced sometime btween (1900-1907) has a small 3/4 inch single pipe thread plug for an inspection hole. The second style inspection cover produced around (1907-1910) has a 4 bolt, 4 inch round cover.  You don't see to many Detroit engines with this second style cover only produced for a couple years. The third style inspection cover was produced between (1910-1920)  has a 4 bolt, 3 inch sqaure inspection cover . Stationary inspection covers were 4 bolt, 3 inch sqaure and stayed the same from about 1907-1920. See photo's below.

 

1st early style Inspection hole 1900 - 1907





2nd Style Inspection Cover 1907 - 1910




3rd Style Ispection Cover 1910 - 1920



Stationary Inspection Cover

 

Also if you have a Detroit type stationary engine with two flywheels that has no name tag it will be difficult to figure out who the manufacture is unless it is a Middleditch or Bessemer these engines are fairly easy to identify from a DEW or DMCSC by looking at the fuel injector, exhaust manifold, engine base, cylinder shape, etc..

Peterson Automatic Fuel Feeder-Injector
Designed by John & Frederick Peterson, manufactured by Benjamin J. Middleditch.

The early two piece Automatic fuel feeder-injector (patent # 926,892) was designed by John Peterson and Frederick O. Peterson patented on July 6, 1909 manufactured by Ben J. MiddleDitch for DEW. It appears that this fuel injector was produced a number of years before being patented  in 1909.  A DEW engine catalog dated 1907,1908 shows this same fuel feeder-injector with a ribbed fuel reservoir cap, see photo's below.  Original literature shows that this early style fuel reservoir-injector was used on DEW, DMCSC stationary and Marine engines. At this time I do not have proof that this reservoir-injector was used on other brand name engines but there is a good possibility that is was.

Sources = (1906-1908 DEW Catalog), (U.S. Patent # 926,892), (1909 DEW Catalog), (Part List Bulletin No. III Jan 1st 1912), (Parts List Bulletin No. III part 3 Nov 1st 1914), (1915 DEW Catalog), (Information embossed on Peterson fuel feeders).


The early two piece style fuel reservoir/injector first appeared around the 1907-1908 time period and the reservoir caps were changed over the next few years. Three different Style caps were manufactured. (1st) Ribbed no embossing, (2nd) Embossed Patent aplied for, (3rd) Embossed patented July 6, 1909.

Barthel Automatic Fuel Feeder- Injector
Manufactured by Detroit Engine Works.

The one piece fuel feeder-Injector (patent # 1,026,425) were designed by Frederick Barthel sometime before 1912 and then patented May 14, 1912 manufactured by DEW.  There were 3 styles of this one piece fuel feeder/Injector produced. All three styles are believed to be patented under the same patent number. They are listed below in the order in which they were produced.

1st style:  flat top with hex cast on the top.  2nd style:  flat top with a U shaped tube on the top.  3rd style: Acorn hex top.  

Sources= (U.S,Patent # 1,026,425), (Part List Bulletin No. III Jan 1st 1912), (Parts List Bulletin No. III part 3 Nov 1st 1914), (1915 DEW Catalog).

1st style                                           2nd style

Literature shows the first style being used on DEW, DMCSC stationary engines.  I'm sure that all three style fuel feeder injectors were probably used on other make and/or style engines.

I have literature that shows the second style fuel feeder injector was used on DEW, DMCSC, CEC stationary engines.

This 3rd style fuel feeder injector with the acorn top was also introduced around the 1911-1912 time period. Literature shows that these fuel feeder injectors were used on all DEW, DMCSC stationary engines with two flywheels. Also used on some of the DEW, DMCSC single flywheel stationary and marine engines.

Detroit natural gas air intake valve.


Originally sold as an accessory from the Detroit factory. Used as an alternate to the fuel reservoir/injector.

______________________________________________________________________________________________________________

 

Some of the 3rd style fuel feeders had a primer cup valve that was mounted to the top of the acorn cap or the side of the reservoir, This allowed you to prime the fuel reservoir after the engine had set for a period of time and the fuel had evaporated or seeped down to the fuel tank. This primer cup valve would save you the trouble of having to find a wrench and remove the reservoir cap every time. Injector tubes are made from standard 1/8" copper tubing with 1/16" inner
diameter. Injector tube should adjusted as close to piston with out hitting it.  Length of injector tube will vary depending on what horse power engine you have.

Water Injection

     In the early 1900's most engine companies who manufactured kerosene type engines used water injection. The   literature below is from the Detroit Motor Car Supply Company catalog about their Sandow engine explaining why they use water injection. DEW, DMCSC, CEC all used water injection on their larger engines.

In the factory DEW parts catalog they call this a Comet Magneto sold for $9.00 new. This is actually a small alternator with a rubber friction wheel that you would drive against the flywheel, some times called a battery saver. You would start the engine using a dry cell battery and buzz coil. Once the engine was running good and steady you would flip a switch disconnecting the battery and connecting the alternator. Alternator would now supply alternating current (AC voltage) to the buzz coil. The buzz coil contact points last much longer using (AC) alternating current rather then (DC) direct current. For more information on ignition see DEW wiring diagram above.

Marine & Stationary Engine Info

Research shows that DEW, DMCSC, CEC  marine engines were offered in many different configurations over the years. An assortment of carburetors and mixers manufactured by different companies, DEW, Schebler, Lunkenheimer,  Essex, Krice, Williams, Lavigne are just a few that are known to have been used.  Ben J. Middleditch  manufactured the first fuel injection systems that were used on some of these marine engines. Then DEW manufactured three different styles of fuel feeder-injectors in the proceeding years after. 

Different configurations of castings were used on the crank case, cylinders, exhaust manifolds, mufflers, etc..through out the years.  Two or three different styles of timing controllers were offered. A few different versions of condenser exhaust manifolds were produced.  Original literature shows that DEW single cylinder (marine engines) were manufactured with three or four large holes in the flywheel or a combination of large holes and small holes. There were a lot of engine companies including DEW, DMCSC, CEC, CPMC, MSBC, DBC, Termaat & Monahan Co., Etc.... that had different combinations and quantity of holes in the flywheels.  Trying to identify the different brand of marine engines by how many or what size holes are in the flywheel simply does not work. Collectors have also tried to use the location of greasers or grease cups on the end of the crankshaft as a means to identify certain engines, again this does not work. You will see examples of engines on original literature and photos on this website that will prove that all these theories do not work. 
The smaller DEW marine engines used a gib key to secure the flywheel. The larger DEW marine engines used a tapered end crankshaft with nuts to secure the flywheel.  Below is the patent for the condenser exhaust manifold for the Termatt & Monahan engine. This same basic design was used on many of the Detroit marine engines. To all the marine engine collectors who are restoring one these engines with this type of condenser manifold please be careful. The pipe that goes down the middle of the condenser has two or three small pin holes to allow a very small amount of water into the manifold. Some of the water will condense and go out with the exhaust fumes. Excess water will go out of the drain at the bottom. During restoration you should take this manifold off the engine and make sure the pipe inside the manifold is not plugged up with rust or carbon. Also make sure the pipe does not have any rusted through holes or cracks. If to much water is allowed in the condenser manifold and the water level becomes higher then the exhaust port then water can enter into the cylinder and there could be an explosion.  If you are running the engine at a very slow idle like at a show you may not damage anything. However if you have the engine in a boat and are running at a higher rpm there could be an explosion from liquid lock.  The later model Detroit marine engines have a needle valve on the top of the manifold where you can control the amount of water that goes in.

 
                                                                                                                                                                                  

DEW, DMCSC, CEC engines manufactured before 1912 had poured main bearings and lower con rod bearing.
All engines manufactured in 1912 and after had interchangeable main bearings and lower con rod bearing.  

* The 8hp was the only stationary engine that had bolt on internal counter balance weights for the crankshaft.*

Source = (Parts List Bulletin No. 111 Jan 1st 1912), (Parts List Bulletin No. 300 March 1st 1916).
________________________________________________________________________________


DEW & DMCSC (Stationary Engines with two flywheels) Some time between 1913 and 1914 a new cylinder style change was made on 5 hp all the way up to 20 hp.  Exhaust port changed from direct pipe thread into the cylinder to bolt on flange type manifold elbow. The bottom water inlet also changed to bolt on style flange. The position of water port on top of cylinder changed by 90 degree's. The place were the oil line screwed into the cylinder moved from the left side of the cylinder to the right side. The (Lower Con Rod) oil line that screwed into the crank case on the right was moved to the left side. The 4hp and under engines still used the old style cylinders that did not have the bolt on flange for the exhaust and lower water inlet. 
Sources = (Parts List Bulletin No. III Jan 1st 1912), (Parts List Bulletin No. III part 3 Nov 1st 1914).

 DEW & DMCSC (Stationary Engines) Between 1913 and 1914 new cheaper governor linkages was introduced with stamped out of flat metal that replaced the heavy cast metal linkages. 
Sources = (Parts List Bulletin No. III Jan 1st 1912), (Parts List Bulletin No. III part 3 Nov 1st 1914).

Single drip oiler's or double drip oiler's offered on all single cylinder engines. These oilers came with check valves built into them, This kept the crank case pressure from blowing the oil in the line back into the oiler. One oil line lubricated the big end of the connecting rod. The second oil line lubricated the piston and the small end of the connecting rod.     

The oil system on the single cylinder engines are drip feed not pressure feed from the crank.  Although a small amount of vacuum from the crank case does help pull the oil into the engine. Check balls in the oiler prevent pressure from the crank case to enter the oiler. The lower end connecting rod and crank journal is force feed (positively feed) by centrifugal ring oiler that is connected to the crank shaft but the amount of oil that is force feed is still regulated by the drip oiler. The diagram and photo below shows how the oil gets to the centrifugal ring oiler which is a disk with a curled up outer ridge, the oil drips into the outer ridge and is centrifugally forced into a hole that leads to the crank journal for the connecting rod and bearing.

Centrifugal_Oil_Ring.JPG (91772 bytes)  DEW_3hp_CrankShaft_Oil_Ring_04.JPG (48852 bytes)

Some of the larger two cylinder DEW engines did have pressure feed oil systems. A oil pump that was belted to the crankshaft with multiple oil lines through out the engine.  Sources = (1909 DEW Catalog), (Parts List Bulletin No. III Jan 1st 1912), (Part List Bulletin No. III part 3 Nov 1st 1914), (1915 DEW Catalog).

  Original DEW literature states that Serial numbers were stamped in at least one of the following places. Top of the cylinder, Outer diameter of flywheel, Flywheel hub face, End of crankshaft, Engine name plate. Serial numbers were stamped in with steel stamps. Embossed or raised numbers and letters are casting numbers not a serial number. I have no information on dating the year of a engine by serial numbers. I don't believe anyone has this information at this time, Sorry.... Although your engine can be dated as being a early, mid or late model by the type of fuel feeder-injector, governor controls and in some cases exhaust manifold.
Sources = (Part List Bulletin No. III Jan 1st 1912), (Parts List Bulletin No. III part 3 Nov 1st 1914).

DMCSC (Sandow) hopper cooled engines were first introduced in 1911 sizes 2.5, 4, 6 hp. We know these style engines were still being produced in 1914.  In 1911-1912 the new style one piece acorn cap fuel feeder-injector was introduced.
