So long as the chains are kept tight they cannot become unlock ed The hooks should also be turned or faced ii such way that they will not be likely to catch the passing plants or rubbish.
 Clevis Is Adjustable.
 The clovis O D is simply hinged, so that there will be no tendency to pull the front of the machine off of the ground. and it is also broad enough in front to allow of the point of draft be- | ing moved from one side to the other. so that the front of the machine may 1 be thrown closer to one row if desired The front guard on each side, a b d, is made of one piece of spring steel seven eighths by three-siXteenths of an inch. This size seems sufficient ly strong and best adapted to carry the tension of the chains d while still yielding to the pressure against the bases of the plants as they may strike the outer sloping ends near q. The inner ends of these guards a b are horizontal. about eighteen inches , each in length. and serve to carry the 1 front guard above the draft bar m and, passing through the keeper q, guide in the adjustment for width. 1 The machine cannot be extended be- 1 yond the bent ends at or closed be yond the angles at b.
 How to Adjust Chains.
 The vertical section between b and C is about twelve inches long, so that the remainder of the front guard from c to near q will be about four inches above the ground. This prevents tho pushing of dirt and squares toward l the plants and allows the chains to catch them where they lie. The hoell# at d and c are therefore bent down. ward and somewhat backward threuGit about five CT six inches. Care must be taken. especially in forming the oute'' ends between and d, to secure heS- results. The downward bend for the nook at a should not be abrupt, as ;t gradual slope helps to prevent catch. ing on any obstacles. The hooks q. f and are formed so as to hold the chains firmly and yet not interfere with the passage of rubbish.
 The method of carrying the rear ends of the outer chains is shown ar ihg The piece k l is nearly paralle. with the chains and may be used for their proper adjustment as to tension, by several holes near the end where i: is bolted at k The chains are be, tween thirty and thirty-six inches long The stand S. upon which the handles are pivoted by one-half inch bolt, i" made of a piece of boiler plate ben: and cut so as to have a horizontal to1' surface about four inches square and standing about two and one-halt inches above the draft bar. to which i. ] is securely botcd.
 Handles Adjust Chains.
 Thr handles are bolted. as at r. f" the heavy pieces of iron (about two b" one half inch tire SteeD. which ara bent to receive them just behind the ,,{,, ,iy,tC Cf un to bring the handles to the prope' height and position In front of these pieces bearing the handles need not be so heavy and may therefore b.. tapered and welded to smaller steel running forward to b. where it i. bolted to the front guard. The opera tion of this arrangement is similar to that of huge pair of shears. When the handles arc pushed apart the from of the machine is spread wider.
 The braces j c serve to support. strengthen and carry the front guard. They are rivetad to the adjusting irons at i. one above and one below the shear" pieces. to prevent their inter- ference with the closing of the ma chine. At this iron is bent to con form to the front guard. to which it is riveted between and l. at which point it is bent downward and forms the hook @.
 Made of Tire Steel.
 Ordinary tire steel about one by one , fourth inch may be used for all ,arts like the clevis o D. rear arches f h m and g and braces k l and i c Q The front guard d should be of spring steel. as specified The rivet heads on the front guard should be round and fiji smoothly. In nearly all other places the irons are fastened to-
