on the top of the carriage a cross slide 98, Figs.

with respect to the track 96, or toward and away
from the die heads. Thus, the cross slide 98
provides for line spacing movement, the plate 42
‘being supported on the cross slide 98 by releas
able clamping means such as the clamping jaws
99, Fig. 10.
As shown in Figs. 8 and 10, the jaws 99 are
75 carried on a mounting member I88 which is de
2,405,786
tachably secured to the cross-slide 98 by means
described hereinafter, the member I80 having
upstanding bearing lugs I?'l thereon in which a
jaw-supporting shaft ‘N32 is j'ournaled. The two
jaws '99’ and 95", Fig. '10, are in the nature ‘of
opposed ‘plates, ‘the lower one 99' of which car
ries lugs H13, Fig. 8, through which the shaft 482
rotatably extends, and the upper jaw 99" has a
pivotal connection with the iower jaw 99’ .‘by
means ‘of pins NM extending loosely ‘through the
two plates 99’ and 99". These pins I04 have
securing wires 135 extending 'therethrough on
the outer sides of the two plates, 99’ and 99"
and the pins 10-4 .and these plates are so ?tted as
to permit slight pivotal movement for clamping
and unclamping ‘of a "printing plate 42.
To provide for clamping of the jaws 99, the
plates '99’ and 99” extend at their rear ends so
as to embrace opposite sides of the shaft M12,
and the shaftis flattened on opposite sides there

the plate. It will be understood that such rock

loading position takes place in the ‘normal use of
the machine while the carriage 15 is located at
one side of the embossing position.
As herein shown the ‘mounting member Ill-0,,
Figs. 8 and 10, is secured on the cross slide 98 by
means which ‘provides for adjustment of the
mounting member parallel to the path of the
carriage, and also which provides for adjustment
of the mounting member .so that the plate 152
carried thereby is positioned with its axis par

parallel to the carriage path, and a 'iixed depend

mounting member Hi0 into the slot H3. For co
operation with the other slot H3’ a pin H4’ is
provided which is ?xed eccentrically on a small
"disk H5 mounted in the bottom of the member
