COTTON WAREHOUSE CONSTRUCTION. 15 
bales, can be constructed for less money than where the outside 
walls are of standard brick construction. There would be only a 
slight difference in insurance rates. | 
STANDARD IV.—COTTON WAREHOUSE WITH OPEN COURT OR YARD. 
Construction of building—The outside brick walls should be not 
less than 13 inches thick, with or without a standard parapet, for a 
one-story building. (See p. 32 for required increase of thickness 
for additional height.) The roof should be of slate, metal, or standard 
composition. The building must be subdivided into compartments 
with a storage capacity not exceeding 1,000 bales each, or 72,000 
cubic feet. The division walls should be of brick not less than 17 
inches in thickness, and should rise at least 2 feet above the roof 
and extend at least 3 feet beyond the apron of the roof. The joists 
of compartments should rest on ledges, metal hangers, or metal wall 
plates. Each compartment should have one or more outside (not 
court) standard doors, not more than 40 feet apart, opening outward. 
The fioors should be of earth, shell, concrete, or other noncom- 
bustible material. The standard width of the open court from shed 
to shed is 100 feet or more. In figure 4 is shown an approved dia- 
gram for this type of warehouse. 
Doors to court.—Sliding doors to the open court should be of light 
frame construction, covered with approved terneplate, with single 
hook jomts running horizontally and double lock seams running 
vertically on each side. The space between the two layers of tin 
should be filled with asbestos, magnesia, or some similar fire-resisting 
substance. A rolling, corrugated steel shutter which can be easily 
rolled or pulled down may be used in lieu of sliding doors. All slid- 
ing doors must extend at least 3 inches over the masonry at the sides 
and top of doorway openings and lap over each other at least 6 inches. 
The rail or track should be of wrought iron, secured to the walls with 
bolts passing through the walls, and fastened with washers and nuts. 
The hangers should be of wrought iron and fastened to the door by 
bolts passing through it and secured with nuts. Binders of iron, 
secured to the masonry in the same manner as catches and hanger 
blocks, should be used. The binders should be so placed at the top 
as to prevent the doors from rolling off the track at either end, and 
at the bottom to hold the door in position when closed. 
Fire protection.—A connection of not less than 6 inches with a 
city main of at least equal size should be required. One standard 
fire hydrant should be provided for each three compartments or 
fraction thereof, with not less than 100 feet of 24-inch cotton, rubber- 
lined hose attached to each hydrant at all times. A standard hose 
house, fully equipped, should be erected over each hydrant. Six 
or more fire pails filled with water should be suspended in front of 
each standard compartment and press room, and a proportionately
