hook Is as wide as will pass through
 the length of the link and narrow enough at the middle of the bend to allow the link to turn and bag the ' other way. So long as the chains are < kept tight they cannot become unlock
 ed. The hooks should also be turned { or faced in such way that they will X not be likely to catch the passing Y plants or rubbish.
 & cIevis Is Adjustable.
 The clovis p is simply hinged, SC \ 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, ' % that the front of the machine may Z 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 s ly strong and best adapted to carry the tension of the chains d g while still yielding to the pressure against the bases of the plants as they may
 strike the outer sloping ends near d. \ The inner ends of these guards a b are horizontal, about eighteen inches each in length, and serve to carry the front guard above the draft bar m and, nassing through the keeper q. guide in the adjustment for width. Z The machine cannot be extended be. yond the bent ends at or closed be
 yond the angles at b.
 How to Adjust Chains.
 The vertical section between and
 is about twelve inches long. so that the remainder of the front guard from to near will be about four inches above the ground. This prevents the pushing of dirt and squares toward the plants and allows the chains to
 catch them where they lie. The hooks I at d and are therefore bent down ward and somewhat backward through about five or six inches. Care must be taken. especially in forming the outer ends between and d. to secure best results. The downward bend for the nook at a should not be abrupt, as gradual slope helps to prevent catch. ing on any obstacles. The hooks at and are formed so as to hold tho chains firmly and yet not interfere with the passage of rubbish.
 The method of carrying the rear ends of the outer chains is shown at h g. The piece is nearly paralle, with the chains and may be used for <ho3r nvopor di,,cf tO tension by several holes near the end where 1t 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, ia made of piece of boiler plate ben. and cut so as to have horizontal top surface about four inches square and standing about two and one-half inches above the draft bar, to which i. is securely bolted. ssss. ,ssss s' Handles Adjust Chains.
 The handles are boted, as at r, to the heavy pieces of iron (about two by one-half inch tire steeD, which are bent to receive them just behind the pivotal point at x, at such an angle as to bring the handles to the prope; height and position In front of X these pieces bearing the handles need not be so heavy and may therefore be tapered and welded to smaller steel running forward to b. where 1t ia bolted to the front guard. The opera ton of this arrangement is similar to that of a huge pair of shears. When the handles are pushed apart the front l of the machine is spread wider.
 The braces serve to support, ] strengthen and carry the front guard They are riveted to the adjusting irons

 Made of Tire Steel.
 Ordinary tire steel about one by one
 fourth inch may be used for all parts
 like the cievis p. rear arches b ID
 and b 6 and braces k 1 and c e.
 The fro1t guard a b c should be
 of spring steel. as specified. The rivet
 heads on the front guard should be
 round and fit smoothly. In nearly all other places the irons are fastened to- ' gether by one-four;h inch square head
 Cd bolts. with washers as needed.
 Although the chain cultivator was
 designed primarily for bringing the
 squares to the middles. 1t was found
 h field practice to have most i'm.
 portant cultural effect.
 In order thai the Use of this machine
 could be 0biained by all farmers al
 the smallest possible cost patent
 mas been taken nnt in the name of the
 department nf agriculture and for tht
 benefit of rnc people If the United
 States. Under this patent 1t is i'm
 possible for any ,ne to manufacture
