Krupp Sliding Block
Krupp in Germany during this period (1864 - 1880s) in contrast adopted "Horizontal sliding block" breeches, rather than screw breeches, for all artillery calibres up to 16 inch naval guns. This was similar in some ways to the original "Armstrong screw" : the shot and powder cartridge were inserted through the open rear end of the breech into the gun bore, and a steel block was slid home into a horizontal slot cut through the breech to close the rear end of the breech. However, unlike Armstrong, Krupp loaded the powder propellant in a metal cartridge case much like a large rifle cartridge, which expanded against the chamber wall on firing and effectively sealed the breech. The sliding block, in both horizontal and vertical forms, and metal cartridge case continued to be the preferred German breech system until after World War II, and is still used by some modern artillery.

Famous quotes containing the words sliding and/or block:
“Here at the fountain’s sliding foot,
Or at some fruit-tree’s mossy root,
Casting the body’s vest aside,
My soul into the boughs does glide:
There, like a bird, it sits and sings,
Then whets and combs its silver wings,
And, till prepared for longer flights,
Waves in its plumes the various light.”
—Andrew Marvell (1621–1678)
“Being dismantled before our eyes are not just individual programs that politicians cite as too expensive but the whole idea that society has a stake in the well-being of children down the block and the security of families on the other side of town. Whether or not kids eat well, are nurtured and have a roof over their heads is not just a consequence of how their parents behave. It is also a responsibility of society—but now apparently a diminishing one.”
—Richard B. Stolley (20th century)
