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 floors should be of earth, shell, concrete, or other noncom-

Doors to court. — Sliding doors to the open court should be of light 

 frame construction, covered with approved terneplate, with single 

 hook joints running horizontally and double lock seams running

 substance. A rolling, corrugated steel shutter which can .be easily 

 rolled or pulled down may be used in lieu of sliding doors. All slid-

 and top of doorway openings and lap over each other at least 6 inches. 

 The rail or track should be of w T rought 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 2^-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
