CASTING AND DISTRIBUTING.
The first step is now finished. The line is rendy

moves lever and goes on with
his work Mt the keys, leaving the machine
10 do the rest. And 1t does IL quickly and well.
As the lever moves, the spac".bnnds spread the

pot.full Of type metal constantly nj liquid heat
and while the moulded edges OF the matrices are
held against the disk, an automatic force. pump

In an instant block Is formed OF the size and
