3-in. X I -in. Oregon set i inch forward from inside face. Thie doors are 

 made from the piece of sheet iron cut for the port liole, backed with 

 three pieces of 3-in. x i-in. Oregon. 22 inches long, to fit close in to the 

 stops. Thev are held in position by the pressure of the silage. 



The Elevator. — The length of the ele\-ator will \ary with the local 

 conditions, whether the ground is sloping, whether the cutter is mounted 

 on a stage, and so on. In general, the length necessary is about 30 feet. 

 A ibox having sides made of three 6-in. x i-in. tongued and grooved 

 flooring boards with top and bottom floors of two similar boards, with 

 a cover of 6-in. x j-in. lining boards is all that i.s required. This cover 

 should be fixed in 6-ft. sections to allow of easy removal should it be 

 necessary to get at the chain. The sides and bottom floor are secured 

 by ledges of 6-in. x i-in. flooring about 4 ft. 6 in. apart; the sides are 

 further strengthened with diagonal braces between ledges of 3-in. x i-in. 

 Oregon. On the upper floor, which is 5 inches below the upper edge of 

 box, it is advisable to nail two 6-in. x ^-in. boards cut down to 5J inches 

 to form a groove for the chain to run in. This floor is supported on 

 6-in. X ij-in. oregon bearers spaced about 4 ft. 6 in. apart. The ground 

 must be excavated to a sufficient depth under the chaff-cutter to allow 

 the end of the elevator to come directly beneath the chaff-cutter, or the 

 cutter may be raised on a platform for this purpose or both may be done 

 as shown in drawing. The end of elevator being put in as far as possible 

 below the chaff'-cutter, a shoot is made with pieces of sheet iron or of 

 wood to connect the cutter, the whole being boxed in as far as possible. 

 It is essential that this shoot should be as steep as possible to prevent 

 the silage from packing up. The drive from the cutter will send the 

 slats up the top or the bottom floor, according to the side fed from. 

 Looking towards the silo, if the feed be from the right hand, the elevator 

 will work up the bottom floor. This is the most advisable, as the throw 

 ot the cutting wheel is then assisting to run the cut stuff down into the 

 foot of the elevator. It wdll, however, work satisfactorily, feeding from 

 the other side, so that the cutter may be put where most suitable for 

 feeding. The ground end of elevator is rounded off with galvanized sheet 

 iron, allowing just sufficient room for the slats to move round sprocket 

 wheel when the adjustable bearings are fully extended. The line of this 

 iron will be described with a radius of yf inches from centre of sprocket 

 wheel. The cover of elevator is left off as far as the first ledge, about 

 5 feet from the ground end. The bottom floor of silo end of elevator is 

 cut back 18 inches and provided with a galvanized iron lip; this is to 

 prevent the slats striking against edge of bottom floor when the silage 

 is being carried up on the top floor. The end of elevator is to project 

 into the top of silo 21 inches. The top floor of silo is cut back from 

 ground end 11^ inches and the silo end 10^ inches; the groove at each 

 end is cut back a further 5 inches to allow for the working of sprocket 

 wheel. The adjustable bearings are attached to the outside of elevator 

 with two 2^-in. x ^-in. bolts to each bearing, a f-in. iron washer being 

 placed between head of bolt and inside of elevator. The bearings for 

 the ground end of elevator are fixed so that the centre of spindle is 

 8| inches from top of box and loi inches from ground end when the 

 bearings are fully extended. The spindle should be fixed in this posi- 

 tion when the elevator is working. The bearings for the silo end of 

 elevator are fixed so that the centre of the spindle is 8^ inches from top 

 of box and 9 inches from silo end of elevator. The slats or buckets 

 for carrying the silage are of 3-in. x i-in. Oregon chamfered on one
