KNIFE RACK. 
(Fig. 17.) 
Knife racks hold the supply of breaking knives while draining, 
during sterilization, and before use by the breakers. Racks with 
a capacity of 18 knives have been found most convenient.

of two pieces of metal, 
1 1 inches wide and 1 1 ^

at the ends. The 
slots for the knives are f inch deep and \ inch apart. The notched 
pieces may be made of galvanized iron 0.0508 inch thick, 1 cold rolled 
steel tq inch thick, or monel metal 0.0907 inch thick. 
LAVATORY. 
(Fig. 3.) 
A lavatory with hot and cold water mixer, controlled by knee or 
pedal valve, should be installed near the transfer window, so that 
when a breaker finds a bad egg and has taken the soiled utensils to 
the window, she can wash her hands before obtaining clean equip- 
ment. The knee or pedal valve attachment obviates the necessity 
of touching faucets with soiled hands. A rack for paper towels 
should be located near the lavatory. The relative position of trans- 
fer window, lavatory, can door, and rack for towels is shown in fig- 
ure 3. The lavatory with knee or pedal attachment may be pur- 
chased from firms selling plumbing supplies. 
HOLDERS FOR TOILET PAPER. 
Toilet paper is used for drying fingers during breaking. The 
rectangular boxes ordinarily used for holding packets of sheet toilet 
paper may be clamped to the standard supporting the tray rest of 
the breaking table. This arrangement is very satisfactory, as it 
brings the paper within easy reach of the breaker and keeps it from 
becoming soiled.
