Sunbeck’s design consisted of two rows of interlocking teeth brought together by a slider that works similarly to how a Ziplock bag works. Consequently, it will be seen that the members on one stringer alternate with those on the other, so that when the sliding operating device is moved back and forth, the locking members will be engaged and disengaged according to the direction of movement. Regrettably, Whitcomb Judson died in … British people are you worried about the growing power of germany?
