' Application filed April 19,

To all'whom it may concern: a

Be it known that 1, WILLIAM H. HOLL- MANN, a citizen of the UnitedjStates, residin 1 at Loretto, in the 'countyofLawrence and" tate of Tennessee, have invented oer:

, tain new and useful Improvements in Gulti=- vators,.of which the following is a specification, reference being had to the accompanyg ing drawings. f his invention relates to certain improvements in' cultivators and has relation more position and which means also serves as a 7 fender to preventfcutting or other injury to- J p the plantswhen the cultivator is in use.

rangement of the severalfpa rts of my im- Another object of the invention is to pm; vide a novel and improved arm or lever adapted to be applied in a manner to maintain the ground working elements in sub stantially a fixed position and which member. also serves as a guard. or fender to prevent the cultivatonduring a working operation, from injuring the plants.

- The invention consists 'infthegdetails off construction and'in the combination and my; 7

proved. cultivator whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

as will be hereinafter more fully set forth.

' novel features of my invention will hereinafter be definitely claimed.

Inorder that my 'invention'mayFbe the I better understood, I will now proceed to d escribe the same with reference to the accompanying drawings, wherein: V 1

Figure 1 isa view in top plan illustrating a cultivator constructed in accordance with an embodiment of my invention; and

Fig. 2 is a transverse vertical sectional view taken through the device as illustrated in Fig. 1. v 1

As disclosed in the accompanying drawings, B denotes a beam of a conventional type and with which coact in a well known manner the handle members H. Vertically disposed through the rear por tion of the beam B are the bolts 1 and 2 spaced apart longitudinally of the beam B ticular'arrangeinent is'not essential. I

The strapor-memberi isa'rched so that the samemay extend overthe beam Band rest upon the-upper face of said beam and the central portion of the inemberor strap 7 .is engaged by the'bolt By'this means, i the members e are'efi'ectively reinforced so as to withstand strain imposed thereupon when my cultivator is in use." 1 Carriedby and preferablydis the memberi3 are the members or bolts 8 spaced'apart longitudinally .of said member as a pivot forfthe forward end portionof=- the rearwardly dir'eoted'shankQ. of aground engaging member and which members may be spring teeth or' as otherwise preferred.

the centralportion has also disposed there through the bolt 1 whereby an additional point of attachment forthe ber 10 is provided.

11 denotes a set lever or arm, preferably of metal, and which is provided at one end portion with a foot'or extension 12 adaptedsaid member by the end bolts 8. The .mem 1 I ber 10 is also arched'to extend; over and bridge the 'upperface of the beam B and strap or mem-- v to engage side face-of the beam B and clamped thereto through the instrumentality of the bolt 14 extending both through the beam B and said foot or extension 12. The arm or lever 11, at a point'inwardly of but in close proximity to the foot or exten sion 12 is skewed or twisted, as at 15, whereby the side or flat faces of the arm or lever 11 throughout the major portion thereof are substantially iat right angles'to the side or flatfaces of the extensionor foot 12 so that said leverorg arm 11 may be properly en- 7 gaged withthe adjacent end bolts 6 and 8.

7, With the armor lever 11 in applied pos1- v 15 tion,'the cross member'sB' and 4 are held in substantially a fixed position or against 7 swinging movement and in order that the member or leverill mayimaintain the mem- V bers 3 and 4 indifferent desired adjustments about the bolts land 2, I provide the rear portion of the arm or lever 11' withthe longitudinally spaced openings 16, herein disclosed asfive in number and so arranged to J permit the maintenance of the members 3' and 4 in three different positions. In order to' facilit te the I proper functioning of the arm orlever 11, the portion thereof immediately adjacent the twistor screw '15 is arcuatewhile the, free or rear portion of said arm or lever 8 is substantially straight.

Theportion a of the arm or lever 11 rearwardly ofjthe twist ornscrew 15 is'of such width as to have its outer longitudinal edge or margin extend beyondt he adjacent ends of the members 3 and 4 irrespective of their adjustment; By this means, the arm or lever llserves aspa fender and prevents the adjacent ends of-the members 3 and 4vcoming into contact with the plants during a working operation andfwhich contact would result in thebreaking or other injury of the j plants; "However, my improved arm or s lever, on account of its particular construction and manner of application, a during av working operation, ,will come in contact 'withv a plantand throw or bend the same to one side without :injury thereto and which function I have found of particular advantage in the cultivation of cotton "although it is to be understood that thismaterial benefit would be present should the plants be ofa different character or species;

understood that the arm or .lever .11 con- It is to be stitutes thes'pecific feature of my' present fender. V V v I In testimony whereof hereunto afiix my invention, and for which reason I wish to be understood that I do not limit myself to the use of this arm or lever 11 in connection with a cultivator of the type hereinbefore described and as illustrated in the drawings,

It is also to be particularly noted that extends in advance of the forward cross member 3 and inwardly thereof so that the and it will also be obvious that my invention is susceptible of some change and modification' without departing from the principles and spirit thereof; andfor this reason I do not wish 'to be understoodas limiting myself to the precise arrangement and formationwofv the several parts herein shown in carryingxout my invention in practice except as hereinafter claimed; a 4
