Oil jets

[Dave Mann]

I've finally unearthed patent number 199540 and it reads as follows: " Austin, Sir H. April 18, 1922. Channels in cranks. -One of the cranks d in respect of each bigend of the connecting- rods of an internalcombustion engine has a recess c formed in that face which is towards the direction of rotation, the recess connecting by internal passages c<1>, c<2>, c<3> with the respective crankpin. As the. shaft rotates, oil falling freely or projected from a nozzle D fed from a pump or other source is received in the recess c as the crank passes the horizontal in an upward direction, and is led by centrifugal force to the surface of the crank-pin. Alternatively, the recess c may be formed in that face of the crank which is away from the direction of rotation, in which case oil is received in the recess when the crank passes the horizontal in a downward direction. Where two crank pins connect on to one crank, a recess is provided in both sides of the crank, one in respect of each crank pin, both recesses being fed from the same nozzle."
So the jet lubrication system system was a Seven design but was it the work of Stanley or Herbert?
