24 Claims. (Cl. 82-21)
The present invention relates to slicing and cutting
machines for making cuts in a piece of work at spaced
positions therealong and involves a carriage whose move
ment is controlled. In one form, the carriage is mov
able on a track along the work, to transport a cutting
means which is movable on the carriage in a direction
rest position. The carriage holds a shaft journalled there
on.
A gear fast on such shaft is in mesh engagement
with an elongated member along the track. When such
shaft is revolved, the carriage moves along the track.
A system of gearing on the carriage, includes and is driven
by a gear on said shaft.
The last driven gear of such
system is fast on a journalled shaft which carries a con
trol member thereon. There is a paWl on the carriage
in the path of such control member. Said member may
be a Wheel having a single tooth, or a plurality of spaced
teeth. When the shaft for moving the carriage is turned,
it will be made to stop upon contact of the radial edge of

ating member 107" is movable by the blade-carrying arm
34, to close such motor circuit when the cutting means is
returned to its normal rest position rearwardly away from
the work 33. Upon operation of the motor 106, the car
riage 22 will automatically move to its next position along
pin 125 extending from the wheel 121, holds the block
1-24 swingable thereon. It is evident that upon rotation
of said wheel, the arm 113 will oscillate and the cutting
means will thereby be operated. A motor 126 with reduc
tion gearing means on the platform 108, is arranged to
drive the shaft 122 in which there is preferably inter
posed an electrically-operated one-revolution clutch 127,
since only one revolution of the wheel 121 is required to
effect a complete cutting stroke and return of the cutting
blade 32. It is to be noted that the cutting stroke will be
comparatively slow and the return of the blade to normal
rest position, comparatively rapid, because the arrange
ment shown olîers a quick return motion.
Since the wheel 121 is to commence its one revolution
each time the carriage comes to rest at a station along the
machine, the control switch 128 for operating the one
revolutìon clutch 127, should be closed at every such
occurrence. Any member of, or which turns with, the
gearing system of FIG. 5, cornes to rest at such time, and ‘
therefore may be used as thel instrumentality to operate
such switch. It is most practical that a member on the
shaft 55 shall be used for this purpose. So a cam 129
on such shaft 55 is made to do this work, at every rest
position of such shaft.
