top edge of iron should just reach the pulley when the bearings are fully 

 extended. Slot the iron out at the centre 1^ inches wide and 2 inches 

 back at the end near pulley to enable chain to run through freely. A 

 groove about \ inch deep should be cut in floor at the other end of the 

 tin, to keep the end below the floor level and prevent the slats from 

 catching the same. Four collars and set screws are provided for both 

 spindles of elevator, to be fixed on spindles, on the outside of bearings, 

 allowing i-in. play between collars and bearings. The slats or buckets 

 for carrying silage are 3-in. x 1-in. Oregon, chamfered on one side, 

 checked f inch deep by 3^ inch wide, for the attachments, which are 

 fastened to the slats with two 2-in. No. 14 screws to each, with a 

 V-shaped cut beneath the attachment, to allow for insertion of sprockets. 

 The elevator is nailed together with 2-in. wire nails from inside; the 

 nails well punched, clinched, and then punched again. Great care must 

 be taken that nothing will project inside the elevator which may catch 

 the slats. When running, do not let the chain of elevator get too slack, 

 as veiy often' this will cause a breakage. The elevator of a 100-ton silo 

 is supported, as shown in drawing, with a T-piece (made of a length of 

 the timber used as a scaffold), checked in half-an-inch at top end, and 

 well spiked and fastened to the silo, as shown. Iron buckets are sup- 

 plied instead of wooden slats, for elevating the grain.
