 :. it's life is longer, and there is | :. one instance of q weevil living ,: z from Dec 10 until the following | < October. < j. hook iS as wide as will pass through 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 in such q way that they will not be likely to catch the passing plants or rubbish.
 Clevis Is Adjustable.
 The clovis U D is simply hinged. so that there will be no tendency te pull the front of the marhinc eff of the ground. and it is also broad enough in front To allow uf the point ot draft be ing moved from one side to the othri so that the front of the maell,n" H4H. be thrown closer to one TOW if desired
 The front guard on each side. Il D c q, is made of one piece ot SifiN% steel seven -eighths by threc-siN(ctn;h' of an inch. This size seems sufficient ly strong and best adapted to e-a";'F the tension of the chains d W.iiip still yielding to the pressure "@ainS the bases of the plants as they may strike the outer sloping ends uc,tf q The inner ends of these guards a h are horizontal. about eighteen inches each in length. and serve to carry tllr front guard above the draft bar n m and. paSa;N2 through the keeper q. guide in the adjustment for width. The machine cannot be extended be yond the bent ends at q or closed be y0nd the angles at b.
 How to Adjust Chains.
 The vertical section between D and C is about twelve inches long. so that the remainder of the front guard from c to near d will be about four inches above the ground This prevents tl" pushing of dirt and squares toward the plants and allows the chains ,o catch them where they lie. The iiookH at and are therefore bent down ward and somewhat backward througl. about five or six inches. Care must br taken. especially in forming the outc}' ends between C and d. to secure beS- results The downward bend for thr hook at d should not be abrupt. as q gradual slope helps to prevent catch . ing on any obstacles. The hooks aE and 9 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 a' h 2. The piece k is nearly paralle with the chains and may be used fo' 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 a onehalf inch bolt. i' made of a piece of boiler plate ben and cut so as to have q horizontal tol' surface about four inches square ant standing about two and One-hal' inches above the draft bar. ito which f. ia securely bolt"d.
 Handles Adjust Chains.
 The handles are bolted. as at r. to the heavy pieces of iron tabout two b.. One-half inch tire steeD. which ar" bent to receive them just behind th'A pivotal point at x. at such an angle n' to bring the handles ito the .prope. height and position In front of x these pieces btslring the handles neod not be so heavy and may therefore 'b'' tapered and welded to smaller steel runnin" forward to b. where i, Is boftsd to the fvont guard. The opera ton of this arrangement is similar to thTt of q huge pair of shears. When the handleS uHe pushed apart the front of the machine Is spread wider.
 The braces j q serve to support. strengthen antl carry the front guard. They are .riveted to the adjusting lironS at j. 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 il is riveted between C and l. at which point it is bent down ward and forms the hook C.
 Made of Tire Steel.
 Ordinary tire steel about one by one fourth inch may be used for all onrtS like the cievis D. rear arches h m and b 2 and braces k 1 and C e The front guard 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 onefourth 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 in field practice to have d 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 fin thp name of the
