The shells are dropped by the breaker through the funnel into the 
shell can beneath. 
Specifications. — The funnel may be made of tinned copper 0.0188 
inch thick, zinc, monel metal, or galvanized iron 0.0201 inch thick. 
The top of the funnel is 8§ inches wide and 14f inches long. The 
distance from the top of the spout 
to the top of the funnel is 6 inches. 
The spout is 7 inches long and 5| 
inches in diameter. Both the top 
and bottom of the funnel should 
be rolled on wire 0.1144 inch in 
diameter. 
SHELL CAN. 
Fig. 12.— Shell funnel. 
(Fig. 13.) 
It is advisable to make the shell 
can as large as the dimensions of 
the table will permit, in order to 
lessen the frequency of the removal 
of shells. When there is but little 
space between the top of the can and the lower side of the top of the 
table, the scattering of shells on the floor is also prevented. 
Specifications. — The shell can is usually made of 
galvanized iron, and need not be corrugated hori- 
zontally for stiffness unless under 0.0159 inch hi thick- 
ness. Both the top and the bottom should be turned 
over wire 0.162 inch thick. The diameter of the can 
is 14 inches; the height 23^ inches, J inch less than 
the distance from the floor to the lower side of the 
table top. Ordinary garbage cans may be purchased 
for the temporary storage of shells emptied from the 
cans from the breaking room, the number required depending upon 
the frequency of emptying.

SHELL TAMPER. 
(Fig. 14.) 
A tamper is always needed for pounding down the 
shells emptied into the storage cans, and may be used 
to advantage in the shell cans at the table. When used 
at the table, a tamper is kept hi each shell can with the 
handle projecting through the funnel. 
A Specifications. — The total length is 34 inches. An iron 
bar f inch in diameter constitutes the handle. If the 
tamper is to be used in the storage cans, the cone may 
be made 7| inches high and 5§ inches in diameter at the 
base, or, if used in the shell cans at the table, 6 inches high and 5
