In the apparatus illustrated as my preferred

a pair of sprockets II at the delivery end of the
apparatus and a pair of sprockets i2 at the feed

The pair of sprockets H are mounted upon '

carries also a sprocket I4 which constitutes the 35 -

the slabs comprising the stack and tends to cor
rect any misalignment of the several, slabs com
prising the stack.
The stack, in dropping, also strikes the upper
end of a vertically disposed bar 21 which is il
lustrated in greater detail in Fig. 5. The bar 21
passes through an opening provided therefor in
a plate member 29 which is part ,of the frame
work
of the apparatus and is provided with a cam

notch 29. The bar 21 is held in the position ll
lustrated in Figs. 1 and 5 by means of a spring
member 46 disposed about the lower portion of
the bar "and arranged to permit resilient down

The stack of slabs continues along the con

by a chain and sprocket drive 43 which takes its
motion from the shaft carrying the sprocket I6.
At a time after the alignment of the stack 65
has taken place, and preferably before the stack
has passed completely beneath the driven roller
45, the next succeeding stack of slabs is placed
in initial position by the operator with one of its
ends upon the rear end of the ?rst stack of slabs 70
and its other end resting upon the roller IS. The
friction between the two stacks of slabs is sum
