' cultivators.

The object of the present invention is to improve the construction of cultivators, more especially the means for mounting the spring teeth, and to provide a simple, inexpensive and efficient attachment of great strength and durability, adapted to enable spring teeth in the form of a harrow. tov be readily applied to the tubular barwor beam of a cultivator, and capable of enabling the teeth to be readily adjusted and arranged in various positions, and. equipped alsor with means for securely fastening -,the spring'teeth in any adjustment.of.,the..same.

Another objectofythe;invention is to avoid making a secondthole in a spring tooth and to supportand reinforce .the spring teeth at a point where they usually break. 1 -..1: mWith' thesev and other; objects in, view, the irn'en i u ."ccnsi s-i i the .z i struction. and novel. combinationofgparts .hereinafterfully described, illustrated. in the. accompanying drawings, and. pointedI out in, the claims hereto appended;- it.beingunderstood that various changes in. the; form, proportion, size and minor details, of, construction, within the scope'of the-claims,..may be resorted -to-withoutdepartingfrom the spirit or sacrificing-any of the, advantages of the invention.

In the drawings :Fi'gure 1-is a plan view of a .portion ofma harrow provided with spring teeth mounted and supported in accordance with the present invention. Fig. 2 is an enlarged detail perspective view of one of the attachments. Fig. 3'is a longitudinal sectional'view of the same. Fig. 4 is a transverse sectional View, taken substantially on the line 4-4 of Fig. 3. Fig. 5 is'a similar view, taken substantially on the line 5-5 of Fig. 3. Fig. 6 is adetail view, illustrating the constructionof the rearclampingmember. Fig. .7 is a detail view of one of the tooth-supporting sleeves.

Like numerals of reference designate corresponding parts inall the figures of the drawings. i i

1 and 2 designate front and rear pivotally mounted tooth carrying bars, extending from opposite sides of tubular bars or beams 3 and arranged in parallelism and connected by spring teeth 4. The spring teeth 4. .are connected at their front ends to the front tooth carrying bars 1 by bolts 5, which pierce the teeth and the bars. In order to avoid weakening the spring teeth by making a second or rear hole in the same, they are connected'with the rear tooth carrying bars 2 by means of oblong sleeves or cuffs 6, rectangular in cross section and slidably and adjustably receiving the upper attaching portions of the spring teeth, and secured to the rear tooth carrying bars by bolts 7. The bolt 7, which passes through a perforation S in the top wall of the sleeve or cuff G, is provided with a rectangular head 9, which is interlocked with the top wall of the sleeve or cuff- The top wall of the sleeve or cuff is provided at the lower :face with a rec tangular counter-sink or recess 10v to fit. the

tapered rectangular head of.the.bolt,and the sleeve is providedat the upper face of its top wall with 'anannular bossor fiange 11,

fittingin a circular opening ,12 ofthe tooth carrying bars, as;clearly illustratedlin. Fig. l, of .the drawings; Theupper end Jof' ;the bolt is threaded for the reception of anut 13, and a washerl is interposed between the nut and. the'tooth carryingbars. .The tooth. carrying bars are also connected. at their outer ends by short braces 15, secured to the bar-s1 and-2 by the bolts of the adjacent teeth. The inner adjacent ends of the tooth carrying bars are connected with the tubular bars or beams 3 by means of ap-v proximately oblong brackets 16, consisting of castings and secured to the tubular bars or. beams 3 by means of front and. rear clamping plates or members 17 and 18, connected with the bracket or supporting member 16 by vertical front and rear;bolts,19, 20 and 20. The bracket or supporting member is provided with an upwardly extending marginal flange 21, and it has front and rear supporting-member-with recesses 24, which form seats for and conform to the configuration of the tubular bars or beams 3. The upper clamping plates or members 17 and 18 are also curved to conform to the configuration of the tubular bars or beams- Instead,

i is provided with terminal enlargements and is reinforced by a connecting rib 2G.

The terminal enlargements are perforated for the reception of the front bolts 19 and are engaged by the nuts thereof, the heads a of the bolts being interlocked with the front bosses or cars 22, which have rectangular openings to receive squared portions of the bolts. The rear bosses or'ears 22 are also provided" with rectangular openings to receive squared portions 'ofthe rear bolt 20, and the rear clamping m'ei'nber' 18 is provided at one side with a terminal enlargement 27,-and it "has a cupshapedsocketQS at the opposite side for the reception of a projecting portion'29 of a head 3t) of a handleattaching bar or shank 31. The cup-shaped socket 28 isdownwardly tapered and is provided with interior corrugations 32. The projecting portion 29"of thehea'd' 30 is downwardly tapered to fit in the socket 28, and it is pro vi'dcdwitlr ribs-33, interlocked with the corrugations 32. The head of the; hand-leattaching bar or shank 31 is also provided with ahorizontal annular flange 34, located at the top of the depending downwardly taperedportion' 29 and arranged upon the cup-shaped socket 28. The cup shaped socket and the head: are piercedby the rear bolt 20*, which secures the head in its interlocked relation with the. socketof the rear clamping plate, and enables the handle 35 to be adjusted laterally with respect to the cultivator. The handle 35 is secured to the shank or'a'ttaching bar 31, which is inclined, by means of bolts 36" and 37, arranged at the upper and lower portions of the shank or bar 31. The lower bolt 36' constitutes a pivot for the handle 35, and the upper bolt 37 passes through an arcuate slot 38 of the shank-or bar, and is adapted to secure the handle in its adjustment on the pivot bolt 36. The upperend of the shank or bar is enlarged at the slot- 38. and this adjustment of the handle 35 enables the same ,to be raised or lowered.

The supporting member or bracket is provided with depending front and rear studs 39 and 40, forming pivotsfor and passing through registering perforations of the inner ends of the front and rear tooth carrying bars 1 and 2', whichhave their inner pivoted ends overlapped andarr'anged on the said studs. The front tooth carrying bars are retained on the 'frontdepending stud I 39- by means of a bolt 41. which secures: the front end of a central spring tooth 42' to the supporting member or bracket. The central the annular boss or flange 8, as it is preferred to extend the stud 40 through both of therear tooth carrying bars, and the said sleeve or cuff 43 is secured to the supporting member or bracket by a rear bolt 44. The front. and rear bolts 41 and 44 pierce the de-' pending studs fill-and 40, and their upper ends are arranged 'inrecesses ta-aud- 46 of the supportingmember'or bracket. The recesses 45 and; 456 are formed by hollow bosses and 4. 8; which extend upward to and form seats for the tubular bars or beams 31 The head of the front bolt 41 is fittedin and interlocked with the front recess 45; and its nut 49 engages the lower face of the central spring toot-h. The'nut '51 of the rear bolt 44 is arranged within t-herear recess 46, whichis' of amlibientsize to permit the nut to rotate.

The central spring tooth is fixed with rel'ation to'the supporting member or'br'acket, and'fthe pivoted' toothcarrying bars are adapted to be adjusted backwardly or forwardly to arrange the spring teeth 4 in different 'Jositionsto suit the character of the soil, the size of t'beplants; or other conditions-of the land to be cultivated, and-the teeth are secured in their adjustment by means of bolts 52',- piercing the rear tooth carrying'bars and extending through arcuate slots '53 of laterallyextending arms 54 of the supporting member or bracket.

The laterally extending arms-have curved outer portions, which are slotted for the reception of the said bolts 52, and the upper faces of the" slot-ted portions-of the supporting bar'or member are provided at opposite sides of the slots with corrugations or teeth 55, which are engaged --by corresponding corrugations or teeth 56 of plates or'washers 57. The platesor washers 57, which are perforated for' the receptionof the bolts 52'. are engaged by the nuts thereof and they are adapted to interlock with the teeth of the laterally extending armsatany point. whereby the toot-h carrying bars and the spring teeth are securely held in their adjustment.

The spring teeth, which, as illustrated in Fig.- 1 of the accompanying drawings, are arranged in the form of ham-rows, are also adapted to be adjusted through their conn'ection' with the tubular bars or beams 3, which are movabl'e both vertically and-laterally in the usual manner. As the particular construction for providing the movement of the bars or beams does-not constitute a portion of the present invention, and as the attaching means for mounting the spring teeth on a cultivator may be applied to various kinds and styles of cultivators, a detail description of the particular construction for permitting the movement of the tubular bars or beams is deemed unnecessary.
