Pencil holding clamps
This mechanism is illustrated particularly in
Figs. 3, 4 and 5 to 8 inclusive. The periphery
of the drum is provided with a plurality of reà

I I8’ for receiving the pencils. The blocks I I6 are
disposed radially with respect to the axis of the
drum.
Obviously it is necessary that the pencils be
positioned on the drum in the blocks |I6 with
absolute accuracy and that they be ñrmly and
rigidly held in this position, otherwise the vari
ous operating mechanisms will not beproperly
alined to perform their operations. This is ac
complished' by rigidly clamping each pencil as
it is disposed in the groove H6', the clamping
means consisting of two sets of clamps disposed
