Adams Leaning Wheel grader no.21, outside the original offices the Nungarin roadboard 1910 company catalog, image of Road King No. 12. J.D. Adams & Company was founded in 1885 by Joseph D Adams who invented the first leaning-wheel pull grader and was based in Indianapolis. The company manufactured construction machinery including sheepsfoot ...
A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. [1] These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.
In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.
Hollingsworth was born in Atlanta, Georgia, but moved to Greenville, South Carolina, as a small child.During the last decade of the 19th century, Hollingsworth's grandfather, Pinckney Carson Hollingsworth, traveled between textile mills repairing carding machines, a business inherited by Hollingsworth's father, John D. Hollingsworth Sr. (1878–1942), and one in which Hollingsworth Jr ...
A Crocodile of the Swiss Federal Railways.Each set of 6 driving wheels is driven by a jackshaft between the driving wheels, gear-driven by a pair of traction motors. A jackshaft is an intermediate shaft used to transfer power from a powered shaft such as the output shaft of an engine or motor to driven shafts such as the drive axles of a locomotive.
Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven.
The number of driving wheels on locomotives varied quite a bit. Some early locomotives had as few as two driving wheels (one axle). The largest number of total driving wheels was 24 (twelve axles) on the 2-8-8-8-2 and 2-8-8-8-4 locomotives. The largest number of coupled driving wheels was 14 (seven axles) on the ill-fated AA20 4-14-4 locomotive.
Coupled wheels (UK+) Wheels coupled to the main/side rods, through which the power developed in the cylinders (24) is transformed into tractive power at the rails. [ 1 ] [ 2 ] [ 5 ] [ 3 ] : 28 The weight of bearings and coupling rods on the driving wheels is counterbalanced with cast-in weights to reduce "hammering" on the track when the ...
