(Cl. 198--3l)
The present invention relates generally to an
improved device for use with conveyor systems
extensively employed in the bottling, canning,
and similar industries.
The invention is particularly applicable to that
type of conveyor system wherein a single line of

The valve block |40 is of substantially tri

As shown particularly in Fig. 17, said block is
rigidly maintained in place by screws |14 passing
- through the side walls 48 to engage in threaded
apertures provided therefor in the block.
Valve block |40, as may be observed in Figs.
'1. and 17 through 20, has formed therein three
passageways in the plane of the upper level
ports, and three passageways in the plane of the
lower level ports, of valve |88.
Conversely, the second iilling machine is con
trolled by a compressed air system which in
cludes conduit |81, so that air pressure is sup

machine is in operation.
