   In addition to the .30 Browning MG, BLC started producing .50 caliber M2 Browning machine guns in March 1943. BLC produced a total of 95,419 .30 caliber Brownings and 119,789 .50 caliber Brownings. A book about BLC's contribution to the war, titled Brown-Lipe Chapin Division General Motors Corporation Goes to War, was published in 1944. [4] [3 ...

3. Belt (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Belt_(mechanical)

   Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the ...

4. Differential pulley - Wikipedia

   en.wikipedia.org/wiki/Differential_pulley

   A dumb pulley can lift very large masses a short distance. It consists of two fixed pulleys of unequal radii that are attached to each other and rotate together, a single pulley bearing the load, and an endless rope looped around the pulleys. To avoid slippage, the rope is usually replaced by a chain, and the connected pulleys by sprockets.

   Subsequent cars had a variety of engines, some with two cylinders. The engine drove a countershaft mounted across the car. From this two forward gears were provided by belts to either of the rear wheels with ratios selected by clutches on different diameter pulleys on either end of the countershaft. Braking was by blocks bearing on the drive ...

   Glacier developed the industry's first metal-polymer bearing with bronze and polytetrafluoroethylene (PTFE) lining; these DU® self-lubricating bushes, launched in 1956, are still being manufactured, specified and used today, and its DX® marginally-lubricated bearings, introduced in 1965, are still specified and used for applications where a ...

7. Block and tackle - Wikipedia

   en.wikipedia.org/wiki/Block_and_tackle

   Typical values are 1.04 for roller bearing sheaves and 1.09 for plain bearing sheaves (with wire rope). [11] The increased force produced by a tackle is offset by both the increased length of rope needed and the friction in the system. In order to raise a block and tackle with a mechanical advantage of 6 a distance of 1 metre, it is necessary ...
