This invention relates to box making machines

taloupe crates.
Each head of a cantaloupe crate is fabricated

sides of the machine and nails selectively fed to
the inner and outer divisions of said chucks in
successive nailing operations to accomplish the

center of the machine.
These double chucks are relatively expensive

I9‘I with a pedestal I98 which rests upon the ties
39 and 40 and is secured thereto by bolts I99 which
rails R. The bottom and each side of the crate
is made of three slats S.
The side slats are nailed onto corresponding
pairs of posts of the two heads and the bottom
slats are nailed onto a corresponding pair of rails
of the two heads.
As above pointed out, and as clearly shown in
Fig. 26, the nails driven through the ends of
slats S in securing these to rails R. to form a crate
extend vertically through the pedestal I98, ties
39 and 40, and the strap 200.
Each bracket I9‘I has lugs 201 and 202 in which
is journaled a shaft 293 having ?xed thereto, on
opposite sides of the lug 202, a collar 204 and an
arm 295. Also ?xed on the shaft 203 between said
lugs is an anvil support 206 including a pair of
arms 20? unnited at their upper ends by a post
anvil bearing 208. Welded to the inner faces of
of the arms 201 are tubular sockets 299 in which
bottom are nearer the ends of the slats than are
the nails which are driven through these slats
into the side posts of the crate to form the crate
