times they are a changin’

Inventor Eli Whitney invented the first manual milling machine in the early 1800s after the U.S.government asked him to create a way to produce mass quantities of firearms. Prior to his invention, highly skilled machinists (using mostly files as production tools) were required to create intricate metal pieces. This process took a great deal of time, and few people were qualified. In the 1940s, John T. Parsons refined the manual milling machine into a precision system using data in a reference system. Fast forward to the present, and enter the CNC (computer numerical control) milling machine. With accurate programming data and training, machinists can use this automated process to produce exceptionally precise parts with very little wait time. The hundreds of meticulously designed, individual parts in a complex mill machine lend to…

55/6/1: Origin of curious gear system I have this old gear system from P.M. Gundlach in Bellville, Illinois, dated 1892 that my brother gave me. I don’t know where he acquired it, but I’m curious about what kind of machine it went on and what that machine was used for. If you know any information about it, I would be grateful if anyone could curb my enthusiasm about this piece. Thank you for your time and help. Greg Shaw Roodhouse, Illinois gregshaw1027@gmail.com 55/6/2: Sickle mower year I recently got a Minnesota No. 5 sickle mower. The original colors were green and red. It also has the number 415 on it. It looks a little like a John Deere No. 5. It has a draw bar two-point connection with one dummy wheel in the back. I…

a bit of nostalgia

Back in 1950, my dad had just graduated from the University of Oklahoma with a pharmacy degree. His first job offer was at the Milo Chew Drug Store in Wellington, Kansas. At the time, I was in the sixth-grade, but I loved cars. My first car was a pedal car that my grandmother bought for me during the war for $5. The hardware store in Pawnee allowed her to make payments of 25 cents per month until it was paid for. My folks didn’t have a lot of money, so an allowance was out of the question. I decided that I wanted to make a car that would be fun to drive on the sidewalks. There weren’t many hills in Wellington, but I could push it as fast as I could…

HARVEY EXPO BUILDING CIRCA 1906 40HP FOOS TYPE SE Company The Foos Gas Engine Co., Springfield, OH Year Circa 1906 Serial Number 26174 Horsepower 40hp Bore 13-inch Stroke 20-inch Owner Paul Harvey The Foos Gas Engine Company was formed in 1887 by John Foos. Foos engine production included both Otto and diesel types and continued until 1941. For many years, Foos was the largest manufacturer solely devoted to the production of gas engines. Features Type SE (Special Electric) engines employ oversized flywheels for the close speed regulation necessary in the generation of electric power. The Type SE engine is distinguished by a patented low-tension wipe-spark ignition, three power-operated valves, throttle governing, and disc-style crankshaft. This 1901 engine design is a transition model between 1897 and 1904 Foos designs, examples of which are also on display elsewhere in the museum. History This particular…

‘the twin’ found at last!

The magneto mount was a disaster from the beginning. The mag was not straight on its mount, and the mount itself was off center from the crank on its mounting board. The board was split in two, and its mounting lag bolts were only into the sides of the cart rails by about ½ an inch. Repairing the Magneto The WICO X magneto was bolted to a cast-iron mount plate that had a section at a right angle to the base. This angled section has a hole in it that acts as a cage for the Lovejoy connection between the mag and engine. The magneto also has an impulse coupler that retards the spark for ease of starting. It is set at top dead center compression for initial timing and advances automatically…

the low-tension ignition system

Expressions like “the coil kicks back” add no intuitive understanding and certainly don’t help us troubleshoot a non-running engine. In addition to a nontechnical understanding, I hope I can clarify false statements and claims heard about low-tension ignition systems. There are only two equations in the article, neither need to be used. Battery and coil: get your current up It’s best to begin with the simple coil and battery system then progress to the rotary magneto and igniter system. The equipment used to gather all the data was not exotic: Radio Shack analog multimeter, BK digital multimeter, Harbor Freight frequency meter, variable speed electric drill, rubber hose connector, 6-volt battery, and two less common items — an LCR (inductance, capacitance, and resistance) meter and an oscilloscope. The only tools you need to…
