the plate. They are mortised, tenoned and braced with 

 diagonals exactly as barn framing is done. In this way 

 extremely strong framing units are formed, which will suc- 

 cessfully withstand the heavy racking and bulging strains to 

 which a crib is subjected. Extending across the ends of the 

 crib, both in the bins and above the driveway, are 4x6*8 

 mortised into the posts, to give stiffness to the ends. 



An excellent small grain bin is provided by flooring the 

 joists above the driveway with matched flooring and en- 

 closing the sides with shiplap. The ends of this bin may be 

 made sufficiently strong to resist lateral pressure by setting 

 in 4x6*5, which are mortised into the vertical end posts with 

 the 6-inch dimension horizontal. Should the corn bins be 

 empty when small grain is put in, the diagonal braces shown 

 in the framing plan will prevent any bulging. This system 

 of bracing will not interfere with the swinging of elevator 

 chutes, for it occurs at 8-foot intervals only. The bottom of 

 the grain bin may have several openings with slide valves 

 and chutes to facilitate the emptying of the grain into 

 wagons in the driveway below. 



The corn bins are sided with 1x6 beveled siding; this is 

 brought up on the inside of the studs above the floor of the 

 small-grain bin, so as to admit air along the whole height 

 of the wall up to the plate. Provision can be made for the 

 installation of a vertical elevator within the crib. 



The wide driveway is a feature that is not often seen, 

 but it can be had at a very little extra cost. It can be used 

 for a variety of purposes; it affords an excellent place to 

 keep wagons and implements. Provided with a concrete 

 floor it makes a first-class fanning floor; or if some hogs 

 are kept a better or more convenient feeding floor cannot be 

 had. 



Each of the corn bins holds about 5,500 bushels, or a 

 total of 11,000 bushels; while the overhead bin for small 

 grain has a capacity of a little over 5,000 bushels. 



This crib, instead of bulging, racking, sagging and fin- 

 ally collapsing in a short time, will stand for years, solid, 

 substantial and durable. Good materials reduce the repairs 

 to a minimum. Thirty or forty years of use should see the 

 crib still standing in as good a shape as ever. And with all 

 this, the cost is probably less than 50 per cent more than 

 would be the case had cheaper methods been used.
