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 tna1 they will not be likely to catch the passing plants or rubbish.
 Cievis 10 Adjustable.
 The clovis p is simply hinged, so that there will be no tendency to pull the front of the machine off of the ground, and 1t 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, a 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 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 m and. passing through the keeper q. guide in the adjustment for width. The machine cannot be extended be yond the bent ends at a or closed be yond the angles at b.
 How to Adjust Chains. h :, is about twelve i:l 'leS long. so tha' the rena.Hayt o! i!e front guard from c to near q will he about faul inches above the ground This prevents the pushing of dirt and squares toward the plants and allows the chains '0 catch them where they Ee The hook:; at q and are therefore bent ooWn- ward and somewhat backyard through | about five or six inches. Care must he taken. especially ill forming the outer 1 ends between and d. to secure bes- results. The downward bend for the hook at should not be abrupt, as 4 gradual slope helps to prevent catch, ing on any obstacles The hooks q: and are formed so as to hold the chains firmly and yet not interfer" with the passage of rubbish.
 The method of carrying the rear ends of the outer chains is shown at Ing. The piece is nearly parallei with the chains and may be used for their proper adjustment as to tension by several holes near the end where # 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 horizontal top surface about four inches square ano standing about two and one-half inches above the draft bar, to which i, is securely bolted.
 Handles Adjust Chains.
 Tn. handles are bolted. 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 l uOl OC SO ACoN ' oAu tASASAOAS O's tapered and welded to smaller steel running forward 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. When the handles are pushed apart the front of the machine is spread wider.
 The braces ] c serve to support. strengthen and carry the front guard. They are riveted to the adjusting irons at ], 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 c and l. at which point it is bent downward and forms the hook e.
 Made of Tire Steel.
 Ordinary tire steel about one by one fourth inch may be used for all parts like the clevis D. rear arches h m and b and braces k and j Q The front guard d should be of spring steel. as specified. The rivet l round and fit smoothly In nearly a.l other places the irons are fastened to- gether by one-fourth inch square head ed bolts. with washers as needed
 Although the chain cultivator was designed primarily for bringing the squares to the middles, it was found Tn field practice to have most i'm portant cultural effect.
 In order that the use of this machine could be obtained by all farmers at the smallest possible cost patent has been taken out in the name of the department of agriculture and for the benefit of the people of the Unitet, States. Under this patent it is i'm. possible for any one to manufacture the machine exclusively and to charge unnecessarily high prices.
