Delivery trays I5 and I9 .are mounted upon
tongues 9| and 92 (Figure2) of slide plate I3 in
any suitable manner, such as by .posts I23 and
I24 (Figure 4). These trays have flat bottom

The other arm I31 of hell crank I33 carries acam
roller I38 (Figures 1 and 5) which coacts with
a cam I39 mounted on shaft I 49 to move the bell
crank I33 with a reciprocating action. From the
shape of cam I39 (Figure '1) it will be noted that,
when cam roller I38 rides on the concave portion

?nished cup onto its delivery tray. Thus, primary
plunger assembly II moves downwardly once for
each downward movement of each of the sec

plunger assembly II makes two strokes for each
stroke of plunger assembly M or plunger assem

the sleeve and rod of each plunger assembly move
downwardly and upwardly both in unison and
as separate elements.

The motive power for moving the sleeves and
rods and other moving parts of the machine is
supplied by a motor I59 (Figure l) securedto the
framework of the machine. Motor 959 (Figure 1)
drives a pulley I59 (Figures 1 and 5) through
belt I59 (Figure 1). Pulley I59 is connected to
