front to rear of the carrier I8. The ?ngers are
urged toward each other to assume their closed
between a projection 34 from one of the ?ngers
while the member yields to avoid interference
with the plunger during the return movement.
Pivoted upon the outer end of the bracket 60,
adjacent to the plunger 62, is a latch 82, the
upper end of which is urged by an expansion
and a bracket 36 secured to the support 29. The
spring surrounds a rod 38 pivoted to the projec
spring 84 interposed between it and the bracket
against a horizontal extension 86 from the
relation by an expansion-spring 32, interposed

bracket 36. A nut 40, threaded upon the rear
end of the rod, limits adjustably its forward
movement under the influence of the spring, and,
therefore, the normal separation of the ?ngers.
These ?ngers 26 are hooked at their extremities,
as shown at 42, to engage the breast-corners of 16

it is forced forward by a fork 44 contacting with
opposite sides of the rear of the base ‘and yield

the latch passes beneath the extension to tem
porarily retain the plunger raised and the ?n
gers 26 separated. Now, as the holder travels in
either direction, the operator may insert a base
between the ?ngers. Said ?ngers are released
to grasp the base for the attaching operation
by the action of tripping means. Parallel to the
guide-rod 20, and ?xed in projections from the
bracket 22, is a rod 90, along which a collar 92
may be clamped at any chosen point by a set~
upon a supporting shank 48. For the ?ngers are 20 screw 94. From the outer side of the collar is
provided various adjustments, by which theymay

The holder, consisting of the carrier with the lift
and base-retaining means, is movable upon its
supports between an active position over the die

The arm is held

downwardly and outwardly. Projecting rear
wardly from the latch 82 is a. horizontal pin I04,
