A BRIEF WORD
Within our personal collection of books is an extensive run of American Machinist, plus a run of Machinery, plus numerous other books on machine work. It's always been amazing to us that the machinists of a century ago could build some of the unique machines of the time, given the machine tools they had to work with. At the outset, we're not denigrating the electronic marvels of our time, including the special applications to lathes, milling machines, and other equipment. What we're saying is that we wonder what kind of wonderful things our forbearers might have built if they had had access to some of the equipment we have today.
For instance, take the side shaft engine design. Even today, there are few machinists who will tackle the cutting of spiral gears. Yet, the majority of side shaft engines used them. In fact, they were usually made of about the same diameter, gaining the cam-speed reduction by changing the helix angle of the two gears. Yet, this idea was used extensively in the gas engine business.
Crankshafts were another item. Initially, there weren't any companies specializing in crankshafts, so it was up to the designer to build his own. More often than not it was cut from a solid piece. The steel billet was perforated with dozens of holes and then roughed out with a hacksaw. Others used a built-up crankshaft, and a few bent it in the forge! How times have changed! About the only folks building engines nowadays are the model makers, except of course, for the mass-produced engines.
Even more amazing are the ignition systems used in days of yore. Of all things, the hot tube system was immensely popular for a time. Compared to the state of the art electric ignition of the 1890s and later, hot tube ignition was cheap, it was simple, and it was reliable. Probably its greatest disadvantage was the occasional rupture of the tube. Yet, the early engine builders were able to successfully overcome these problems and provide customers with a simple and reliable form of power.
When doing lathe work, ye olden Reflector much prefers to use carbide bits: they cut faster, and leave a nice finish. Yet, the machinist of a century back didn't have carbide, and in fact, had little more than some tool steel which had to be forged, tempered, and ground in the shop...there wasn't much in the way of off-the-shelf lathe tooling a century ago. This alone, makes the talent of the old-time machinist all the more amazing. When we preserve some old-time engine with swinging arms, revolving shafts, and a fancy governor, we're not just preserving some old castings. . .we're paying constant tribute to those wonderful old-time machinists!
It looks as if the plans are set for the Gas Engine Extravaganza in England this summer. If you're planning to go, send in the forms at your earliest convenience. If you don't have the forms, contact the GEM offices and they'll send out the itinerary and other materials. We're looking forward to seeing many of you on the tour! Don't procrastinate too long though...Wade Farm Tours will need to know how many are going by mid-April, and the hourglass is running out of sand!
Our queries this month begin with:
28/3/1 Duro Engine Sometime back, William F. Derouchie sent us some photos of a Duro engine, but it's missing the ignition system. If you can be of help, contact him at 24349 Beech Rd., Southfield, MI 48034-
28/3/2 Union Gas Engine Ron Kershaw, 22 Gundulu Place, Giralang, ACT 2617 Australia forwarded some photos of a Union gas engine in Australia. It is No. 2444. It has the following dimensions; 5? x 5? inch bore and stroke, and 28-inch flywheels. Ron would like to know more about this engine, so if you can help, please contact him at the above address.
28/3/3 Sun-Power Engines Q. I have a MacLeod engine which is quite similar to the Sun-Power engine shown in American Gas Engines. Did Sun-Power make these engines under contractor with MacLeod? Any information will be appreciated. Mickey Zwack, RR 5, Site 16, Box 16, Prince Albert, SASK, S6V 5R3 Canada.
28/3/4 Standard Motor Company The city of Kokomo, Indiana has a long association with engine and automobile manufacturing. Companies such as Adperson, Haynes, Delco, Kingston, Chrysler, and Satellite have operated in the city. From Kokomo: A Pictorial History, I recently learned the Standard Motor Company manufactured small gasoline engines at 912 North Main Street in the city before 1904. I grew up in Kokomo and would like to have an engine that was made there. Can anyone help identify and/or locate one? Richard Haskett, 2139 Violet Lane, New Brighton, MN 55112.
28/3/5 Hedstrom Motor Q. See the photo of an air-cooled engine made by Hendee Mfg. Company, Springfield, Mass. It is a Hedstrom Motor, s/n WHO. Note the oil sight glass outside the oil line and a pressure tank leading into the base, also a bevel gear off the camshaft. Any information about this engine would be very much appreciated, along with history, colors, applications, and the like. Prince E. Stevens, RR 1, Box 1830, Gardiner, ME 04345.
A. We think the Hedstrom was made for automotive purposes, but have never found much either. Can anyone help?
28/3/6 Fairbanks-Morse In 26/6/16 of June 1991 we ran the following query, but unintentionally omitted the name of the owner, Jim Osnes, 16420 Fillmore St., Brighton, CO 80601. If you can be of help on this query, kindly get in touch with Mr. Osnes:
Q. I have a 1923 FBM 1? HP Z engine, s/n 536505 with a drive gear on the sahft inside of the right hand flywheels to run a pump jack that is bolted to the engine and pump head as one unit. The right hand flywheel had additional casting numbers B-3RJV-ZAJ3. AH other 1? HP flywheels I have seen only have ZAJ3. Both flywheels look the same. The problem I have is trying to find a gear to fit the magneto. I want to set it up as original. It has a Fairbanks-Morse conversion kit to replace the old AB-33 magneto with the newer FBM rotary magneto. It consists of a plate and a gear. Casting No. ZAA2561 A2 is attached to the old AB-33 magneto bracket and cam support. The special gear 33 TEETH Casting No. ZAA2993 A is attached to the plate and is driven by the crank gear with 24 5335h. The magneto runs off this spiral idler gear and not the cam gear, as later engines do. Does anyone have an engine with this conversion? I would like to find out the size and number of teeth on the special magne to gear or load of the parts to make the replacement.
28/3/7 Hatz Diesel Engine Q. I recently purchased a one-cylinder die-el engine made by Hatz of Germany. Model E75 - 6, s/n 10084, built in 1964. There is another number, 166421310 that I don't know what it is. Any information on this engine or the manufacturer would be appreciated. Jerry Elliott, 8624 S.R. 87, Novelty, OH 44087.
28/3/8 C. S. Mersick & Co. Q. See the photo of and engine with the following nameplate information: C. S. Mersick & Co., New Haven, Conn. 1 HP, 600 rpm, s/n 84624. Mersick was a supplier of industrial equipment. The engine is identical to an Alamo Blue Line as shown on page 18 of American Gas Engines, as well as the Rock Island on page 429 of the same book. Any information on this engine will be appreciated. Wayne D. Rowell, PO Box 6, Wilmington, VT 05363.
28/3/9 Humboldt Cutter Q. Can anyone provide information on the Humboldt cutter shown in the photo? 1 especially would like to know when and where it was built. The nameplate reads: Silbaugh Mfg. Co., Humboldt, Iowa. Any help will be appreciated. Charles Obermiller, Route 2, Box 330, Buckholts, TX 76518.
28/3/10 Unidentified Engine Q. See the two photos of an unidentified engine. There is no name tag, nor are the castings marked. The engine seems to be complete with the exception of the pipe from the carburetor to the intake valve; also the governor linkage is a puzzle. The engine appears to have been painted black, with the cylinder painted silver. Any information will be appreciated. Martin Pope, 2 Connacona Crescent, Scarborough, ONT M1E 3P9 Canada.
A. See 28/3/1 above.
28/3/11 Fairbanks-Morse Q. I have a Fairbanks-Morse 6 HP Z engine, s/n 216256. When was it built? Any information will be appreciated. Carl DuMez, 242 - 3rd St., Cedar Grove, WI 53013-0125.
