Реферат: 12,949. Sprague, F. E. June 2. Hinges.-A metal disk 13, inserted in a recess formed in one of the socket pieces, has an opening 14 by means of which it engages an annular groove of the hinge pin 10 to prevent it from working up during the movement of the butt-hinge parts. The opening 14 is large enough to allow the hinge pin to be withdrawn when the hinge is opened out. The disk 13 is also formed with an eccentric piece 15 terminating in a tongue 16 so that the movement of either flap moves the disk into engagement with the hinge pin.
