’I'his invention is a bottle crate intended more
particularly for the retail distribution of milk,
and the invention is directed primarily to a
crate, »so constructed that a plurality of such
53-1 crates may be readily stacked in superimposed
relation and in a manner to maintain vertical
alinement `of the walls of the crates so stacked.

ported .on two of its sides by the inclined por- 55l
tions I2, which cooperate with one another in
supporting the flat top when shocks are re

also diverge from the flat top in the direction of
the plate I0, so as to give maximum strength
in the structure to preclude bending or deforma
tion under hard usage.
The free edge of the ñat top I3 is preferably
with these parts or may be pressed firmly against
said parts, so as to thereby form an anchorage
which will preclude rattling and help to hold the
runners in place.
It will be understood, however, that the walls
of the crate and all of the metal parts which I
have described, are held in assembled relation
by the tie rods 20, which are threaded through the
parts in succession and headed over While the

Each stacking iron is adapted to rest on the
upper surface of one of the corner caps 'I and
to be secured thereto and to the crate primarily
by the means which holds the other parts of the
20 crate in assembled relation. To this end, the
plate Ill of each stacking iron is provided with
countersunk holes I6 adapted to cooperate and

with some extraneous objects, the boss will fend

the ilanges 8 will not be caught and deformed.

corner a ñrrn metal angle to cooperate with the

to secure the corner irons, corner caps and stack
ing irons to one another and to the slats of the
crate in order that the said parts of the crate
may be held in assembled relation by the tie rods
35 20. The upper ends of the tie rods are headed,
as shown at 2l, and these heads are received in
the countersunk holes I6 to give a substantially
flush upper surface to the plate I0.
Tie rods 20, after passing downwardly through
40 said several parts described, and as shown in
Figure 2, are adapted to pass through holes 22
in the lower tongues 4 of the corner irons and
thence through holes 23 in a metallic runner 24,
as shown in Figure '7, said latter holes 23 being
45 countersunk to give a flush lower surface to the
runner and the rods 20 being headed within said
countersunk holes.
The runner 24 is constructed from sheet metal
and comprises a bottom plate 25, all parts of
50 which occupy the same horizontal plane, so as
to give a perfectly flat bottom and at the lateral
edges of this iiat plate 25 are upstanding iianges
26 which extend upwardly over the inner and
outer surfaces of the bottom slats and. over the
55 corresponding edges of the lower tongues 4, so
as to completely enclose and conceal such lower
edges and the tongues and to also enclose and
conceal the lower recesses 6 in which said tongues
are received.

that, when the tie rods are headed over, the
edges of the flanges 26 and 8 will be drawn tightly
The plate 25 is of a length to extend along
the complete length of the side wall with which
it is associated and is turned at the adjacent
corners of the crate and extends for a distance
along the two adjacent side walls, so that said

tongues and recesses, as stated, and at the same
time reinforce the edges of the crate in such
70 manner as to preclude splitting or splintering
thereof. Said flanges are, as shown, offset slight
raised extension of the stacker to be guided
thereby as the crates are stacked into true ver
tical alinement without undue Wear on the parts
and Without contact between the metal parts and
the wooden parts of the vcrate during the stack
ing operation.
As the tie rods 2E] are spaced some little dis
tance from the corner in order to properly secure
the slats together without splitting, there may be
some tendency under the most hard usage for
the stacking irons to lift slightly at their outer
corners and for this reason, I preferably perma 45
nently anchor them down in this region. This
may vbe accomplished by kthe use of a rivet 29
passed through perforations 30' and 3| in the
stacking iron and corner cap and headed over
and properly countersunk, so that the parts are 50
anchored together in the region stated. In lieu
of rivet 29, I may, however, punch out a projec
tion 32 from either the stock of the corner cap or
the stacking iron and then perforate the other
part, so that the projection 32 may extend 55
through the perforation and then be crushed or
headed, as shown in Figure 6, to provide integral
anchoring means. I do not consider this anchor
age as an absolute essential, but it is preferably
employed for the reasons stated.
It will be understood that the runner 24 may
extend along either the longer sides or the short
er sides of the crate, as may be desired,V the
invention not being restricted in this connection.

panying drawings, the interior of the crate con

means for dividing the interior of the crate into
individual compartments for the bottles to
