Abstract: 119,561. Bradley, J. W., and Deans, B. Oct. 20. 1917. Taps.-Fig. 1 is a sectional elevation of a collapsible tap for use in a boring &c. machine, in which the body a is bored to take a central spindle c, is slotted at the end to receive the dies s, and is slotted about its centre to receive a handlever l by which the dies are moved outwards or withdrawn; screwed to the end of the central spindle is a cone w on which the inner ends of the dies bear. It can be adjusted by rotating it by means of the slotted stem w<2>, The dies are drawn inwards by a garter-spring 2. To move the dies outwards, the handle of the lever l is moved towards the rear to push the central spindle and cone to the right. As the lever is moved further, its end bears in a slot in the sleeve n and moves it also to the right so that its bevelled cupped end forces the spring-pressed pins q into engagement with a bevelled groove k in the central spindle to lock the dies. As the dies move into the hole to be tapped, the work bears on a plate t and forces it to the left and with it the sleeve n to which it is attached by rods u adjustable in length. When the sleeve has moved far enough to free the pins q the latter are forced outwards by their springs and are disengaged from the bevelled groove in the central spindle, whereupon the spring c withdraws the spindle and its cone, and the spring 2 withdraws the dies. In a modification, the hand-lever is dispensed with and the parts are moved by hand directly.
