Abstract

896,914. Screw-and-nut gearing. ZAVODY V.I. LENINA PLZEN NARODNI PODNIK. March 25, 1959 [March 25, 1958], No. 10405/59. Class 80 (3). A device for indicating excessive wear of the thread of a split nut 2, 3, which screws along a vertical fixed post 10 and carries, through a sleeve 1, a vertically - adjustable load, for example in a vertical drilling - machine, comprises a non-load-bearing further nut 5 connected with axial but not rotational freedom to the nut 2, 3 by a screw 9 screwed into the nut-part 2, 3 and passing freely through a hole in the nut 5; and a bolt 7, locked to the nut 5, is arranged, when the device is first set up, to have a clearance x from a plunger of a switch 8, mounted on the nut-carrying sleeve 1, the switch plunger having an operating movement l, so that when the wear of the split nut exceeds x+l the switch is actuated to give an indication of the wear or to stop the machine to which it is applied. The part 2 of the split nut is attached to the sleeve 1 by screws 6 and the part 3, which has projections engaging indentations in the part 2 to locate them rotationally, may be moved axially thereof to eliminate threadclearance, by means of nuts 4, 41.
