Figure 2.— A portable shade made of steel tubing and covered with shade cloth. 



Four hinges of the type shown in figure 6. 

 Two turnbuckles, 5 /i6-inch. 

 44 feet of wire, 9-gage, smooth galvanized. 

 7 feet of reinforcing rod, 5 /s-inch. 

 One piece of Saran shade cloth (90-percent 

 solid), 6 by 32 feet. 



A diagram of the portable shade is 

 shown in figure 3. The top frame is 

 made of steel tubing having an out- 

 side diameter of IV2 inches with a 

 16-gage wall thickness. The end 

 frame is made of 3 /4-inch steel 

 conduit. 



The ends are made in a U shape 

 and hinged at the top (figs. 4 and 5). 

 The top corners are lV4-inch pipe 

 elbows and the end corners are 3 /4- 

 inch pipe elbows and conduit 

 connectors. 



To keep the shade standing square, 

 one side of the frame has diagonal 

 wires across it. Turnbuckles (fig. 5) 

 are used to tighten the wires. 



Figure 6 shows the dimensions of 

 the hinges. The top part is welded 

 into a V2-inch hole that is bored 

 in the lV4-inch pipe elbow. The 



other end is welded or pinned in the 

 conduit. Bracing is welded on each 

 end for rigidity and a brace is welded 

 across the center of the top. The 

 bracing is V2-inch conduit. 



The frame is covered with Saran 

 shade cloth that gives 90-percent 

 shade. The shade cloth has a 2- 

 inch hem on all edges with eyelets 

 every 18 inches for tying it to the 

 frame. The stakes are 5 /s-inch rein- 



Protection From Radiation 



Shades protect bee hives from 

 direct rays of the sun. The hives 

 should also be protected from heat 

 radiating from the ground. This 

 can be done by placing the hives on 

 green grass or other vegetation. 



Keeping the hives covered with a 

 good coat of white or other reflec- 

 tive paint also provides heat pro- 

 tection. The paint reduces the 

 amount of heat the hives will 

 absorb.
