Oil feed to the sewing head
The spriral grooves in the hook drive shaft 13 feed the oil from the pan
through the pipe 23 to the basin 3 in the sewing head. The check valve
24 in this pipe prevents the oil from running back when the machine is
idle. The viewing glass 15 allows a checking of the oil feed.
The oil exiting from the brass tube 4 drips onto the foam rubber ring 1.
From here the oil reaches the pin 2 in the hole of the hollow shaft 6.
The pin conducts the oil further to the wick 7 in the hollow shaft 6. The
wick supplies the lubricating points of the linkage and the oil pad 8 in
the sewing head. From the oil pad the oil is conducted directly or via a
wick to the joints.
Oil feed from the sewing head to the hook box
The oil spun off in the sewing head is taken up by the felt pad 9 and
conducted to the recirculation wick 10 lying underneath. The
recirculation wick feeds the oil back into the hook box.
The oil dripping from the foam rubber ring 1 in the basin 3 reaches the
hook box via pipe 5.
The oil spun off by the linkage is caught by the felt plate 11 and led
back to the hook box via pipe 14.
