These nimble aircraft incorporate different upper and lower wing sections that provide inverted performance equal to conventional "right side up" flight. This wing design also facilitates outside loops. The original Pitts design dates from the early 1940s and over the years more powerful engines and various aerodynamic modifications have led to several models that are capable of unlimited aerobatics carrying two persons.

United States of America Wisconsin Racine 1935 1936 between PENDING 1 TANK PAINTED RED/ FRAME PAINTED BLACK   The tractor is a motorized vehicle used to pull and actuate other vehicles or implements that are not power-driven. Tractors are primarily designed for agricultural work: for cultivation spraying and harvesting operations. The first tractors developed in the mid-nineteenth century were steam-powered and were not very mobile: their main purpose was to power threshers and other equipment. The development of gas-engines in the late 19th century and their integration into tractors gave the machines more mobility and flexibility. Robert C. Williams writes in "Fordson Farmall and Poppin' Johnny: A history of the farm tractor and its impact on America" (1987) that "Of all the farm implements the tractor has had the greatest impact on rural life...In one generation between 1920 and 1950 most farms in the United States changed from dependence on draft animals to dependence on mechanical power."   Agriculture Power sources Gasoline             metal 240 188 190       http://source.techno-science.ca/artifacts-artefacts/images/1967.0204.001.aa.cs.png http://source.techno-science.ca/artifacts-artefacts/images/1967.0204.001.aa.cs.thumb.png

STELEWELD-RAYSPEED   General Electric X-ray Corp. United States of America Wisconsin Milwaukee 1930 1950 circa   4 Silver metal frame & back; black board and felt sealing strips; cream-coloured screens/ black leather pulls. typical example of a standard X-Ray film cassette used by doctors to produce a sharper image. Used to hold x-ray film during exposure. Intensifying screens promote more effective absorption of x-rays producing a sharper more distinct image. Example of x-ray film cassette with fluorescent or intensifying screens which are held in contact with the front & back film surfaces. These screens absorb x-rays more efficiently than film alone and produce a sharper more distinct image.

United States of America Wisconsin Appleton 1929 1935 between   1 GREY PAINTED BODY/ RED PAINTED WHEELS & GAS-KEROSENE TANK   The tractor is a motorized vehicle used to pull and actuate other vehicles or implements that are not power-driven. Tractors are primarily designed for agricultural work: for cultivation spraying and harvesting operations. The first tractors developed in the mid-nineteenth century were steam-powered and were not very mobile: their main purpose was to power threshers and other equipment. The development of gas-engines in the late 19th century and their integration into tractors gave the machines more mobility and flexibility. Robert C. Williams writes in "Fordson Farmall and Poppin' Johnny: A history of the farm tractor and its impact on America" (1987) that "Of all the farm implements the tractor has had the greatest impact on rural life...In one generation between 1920 and 1950 most farms in the United States changed from dependence on draft animals to dependence on mechanical power."   Agriculture Power sources Gasoline/kerosene             metal->;resin->rubber 365 190 224       http://source.techno-science.ca/artifacts-artefacts/images/1970.0392.001.aa.cs.png http://source.techno-science.ca/artifacts-artefacts/images/1970.0392.001.aa.cs.thumb.png

The development of gas-engines in the late 19th century and their integration into tractors gave the machines more mobility and flexibility. Robert C. Williams writes in "Fordson Farmall and Poppin' Johnny: A history of the farm tractor and its impact on America" (1987) that "Of all the farm implements the tractor has had the greatest impact on rural life...In one generation between 1920 and 1950 most farms in the United States changed from dependence on draft animals to dependence on mechanical power."

United States of America Wisconsin Oshkosh 1928 1940 between Patents on magneto: 1540609? 1556546? 1557979? 1679321.;Patent on engine: Nov.13 1923 - 1474003 Ricardo Head. 1 Brass magneto & coil box and carburator (the schebler)/ Spark plug primer cup and coolant pipe are on top of head./ coil box is a 'WICO' 12-1/2" flywheel/ Tied to a red square tubed frame/ Engine is green/ Flywheel is yellow. Type of engine bought and used in Canada. To power a boat. The first use of a gas engine to power a boat dates back to ca. 1885 both in Europe and in the United states. After which numerous companies started the production of marine engines. This one has a Ricardo cylinder head which provides a better and faster combustion of the gas with a new design of the combustion chamber. This invention was developed during WW1 by Harry Ricardo of Storeham England for L-head engine. The result is an increase in efficiency and economy (km per litre of fuel) Universal Motor Co. founded in 1913 was initially Termaat & Monahan Co. which started in 1901 in Oshkosh Wisconsin. They began with two-cycle engines and with Universal began building four-cycle engines.
