| HOOK IS as WlGe dS Will pass luFOuSn the length ot 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 ;11 such way that they will not be likely to catch the passing plants or rubbish.
 clevis Is Adjustable.
 The cleyiS 0 D Is simply hinged. so that there will be no tendency to pull the front of the machine of 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 be thrown closer to one row If desired. The front guard on each side, b c 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 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 D are horizontal. about eighteen inches each in length, and serve to carry the front guard above the draft bar III and. passing through the keeper q, guide in the adjustment for width. The machine cannot be extended be- yond the bent ends at or closed be yond the angles at b.
 How 10 Adjust Chains.
 The vertical section between b and c 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 heoks 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 outeS ends between c and d, to secure best results, The downward bend for the book at a should not be abrupt, as a gradual slope helps to prevent catch ing on any obstacles. The hooks ae and are formed so as to hold tho chains firmly and yet not interfere with the passage of rubbish.
 The method of carrying the reui' ends of ile outer chains is shown al Ing The piece k is nearly paralle; with the chains aild ili;iy be used fJ,' their rror2:: @7iustment as to tet1ssot' by several holes near the end where it Is bolted at k. The chains are be tween thirty and thirty six inches long The stand S. upon which the handlea are pivoted by one half inch bolt, i:' made of q piece of boiler plate ben: and cut so as to have horizontal top surface about four inches square and ssfaniius atout two and one.half inches above the draft bar, to which F. is securely boted.
 Handles Adjust Chains. '.
 The handles are boted as at r. t,' the heavy pieces of iron (about two by oue-ha,f inch tire steeD, which ar, bent to receive them just behind tn. pivotal p int at x, at such an angle a.: to bring tho handles to the prope: height and portion. In front of ;: +hese pieces ling the handles nee.i not be so hefvy and may therefore b.. tapered and welded to smaller stee! running forH-c"::l to b. where 1t is bolted to the front guard The opera ton of this arrangement is similar to that of huge pair of shears.

 Mado of Tire Steel.
 Ordinary tire steei, bout one by one fourth inch may .i5s used for all .mrtS S like the cleNis p.;"s;lr arches il m and h and braces k } and i e. The front guard . d. should be of spring steel, as specified, The rivet heads on the front guard should be round and fit moothly In raarly all other places he irons are fastened to- gether by one fourth inch square .,ts;id ed bolts. with washers as needed.
 Although the chain cultivaror was designed primarily for bringing the squares to the middles. it was found In field practice to have a most i'm portant cultural effect.
 l In order that the use of this machine could be obtained by all farmers at the smallest possible cost a patent has been taken out in the name of the department of agriculture and for tho benefit of the people of the United States. Under this patent 1t is i'm. possible for any one to manufacture the machine exclusively and to charge unnecessarily high prices.
