To c?? whom it may concern:

ie it known that 1, Riemann H. ?Uanmir., citizen of the United States, and a resident of osedale, in the county of Bolivar Siete of tississippi, have invented an imprm'einent in Cultivators, orE which the ''oiioivine' is a specification.

rlhe object of my invention is to provide an improved cultivator,especialiy one adapt.- ed for use as a cotton-scraper, harrow, or other analogous implement..

'Fie this end, provide a main draft-beam with two attachments, one being; a. supplepiveted beam carrying a scraper or other cultivating device and ndepted to swing to varjt7 the lateral angle er inoi the ec'aper; and the other at- Ln.clnnent is a, runner and arranged in of the supplemental beem and adopted vertical ediustxnent, to very the depth i the scraper or other tool shall endrarvingr Figure 1 is a side view of Fig. 2 ie a longitudinal veraction oi the same. 3 is a verice cross section on the line 3 3 of Fig. 1. e o vertical section on the line 4--4 numeral 1 indicates the main beem, and 2 the supplemental beam arranged un- 4 der, and perni el with, said mein beam, and

pivoted thereto end provided with a curved pendent steelt, or foot, adapted for attachment o a scraper 3, or other cultivating device. 'lhe depth gage ie arranged in rear of the ainiplemental beam and comprises a runner l which is arranged horizontally and parallel to the main beam and adapted for vertical adjustment relative thereto. The details of construction, arrangement, and option of the two attachments will new be described..

'ihe main benin 1 is constructed of angle ion for the sake of combining;m lightness, si'en;tli, and rigidity in the highestl degree. 'ihe supplemental, scraper-carrying .teem S2, is pirated at its ends in attachments of the mein beam, the forward attachment eonsitting?, of an L-shaped bracket 5 which meg? eet integral with the clevio 6 and is occured te the main beam by the same bolt 'i'. he end of the supplemental beam 2 voted in e pendent iianae 8 formed on il of the hollow guide 10 in which ,1 A, io adapted to slide. The head oi? mi; 11, n :fixed portion o? the the guide 10 is secured to the beam by bolts 12. rlhus, the front and rear attachments` of the main beam serve as the means for ivotine; and su porting the suppleinet-itei eam 2; and'in both cases the attachments lie in Contact with both flanges of the main beam.

As illustrated in Fie. 3, the supplemental beam is adapted to swing; so that the scraper 3 or other attached device may be swunglaterallv to vary its angle to the surface over which the implement is drown. For effect.- ine; such adfustment and for holding; the

scraper er et ier tool rigidly in any position i to which it may be adjusted, 1 provide 'the stop or foot with a lateral ann 13, ond the main beam 1 with an upwardly curved end lateral arm 11i, and connect the two by ineens of a turn-buckle 15. lt is apparent that 'or adjusting?, that is to say, rotetingg, the buckle, ie angle or inclination of the eral erm 13 'will be varied and the s 3 thereby adjusted at e.. greater or l., eroi inclination, as Will be seen by comp-eri son oie iuil and dotted lines in 53.

The vertical adl'ustment of the depth 4 is also effected )y means of a turn-buckle 16 which connects it with an angular brochet, 17 secured on the upper side of the main beam 1. lt will be seen that the poet 1i being rigid with the runner i will hold in the same plane with the beam l and in order to prevent its rotation on the axis 11, the latter is provided with a cross-pin 11n see Fig. lil-Which Works in slots 10 formed in the pendent guide 10. lhus by adjust ing, that is to say, rotating the turn-luidde, the runner may be adjusted higher or lov; Without otherwise affecting` its relation to the mein beam or the supplemental beez-e. it will thus serve as e depth ,entre ani L support ier the rear portion o1? 'the imp; ment teken as a whole.

in order t0 prevent the runner from ding or sliding laterally, it is provided one edge with a downwardly projecting,` l gitudinal rib or flange if-see Figs. 2 and e.

What il claim is l. The combination with a main beam, oi a su plementai beam pivoted beneath end ara lei to the former and having a euitive'b me* device attached, both beams being; vi ed with lateral arms on the same eide, and o turn-buckle connecting; the tree i. oi said arme, as described.

2. The combination with main boem and BEST Ai/Aitnete coe* :t supplemental beam provided with a cui tvnting device, of e. depth gege -conciprisingg n, runner arranged in rear of the cultlvating device, n tnbu ar guide pendent from the main benin, e rigid attachment of the runner ednnted to slide in enid guide, and u turn-timide connecting; the runner with the main beam, ns described.

3.. 'Eile combination with a mitin beam and supplementari beam having; n ieot adapted 'for attachment of n Scraper or other cultivatirof d^-\fce o n depth gege forming an of the main benin rear of l nennen@ the supplemental one, und consisting o tubular guide rigidly attached to the .beam and pendent therefrom, n. runner having post adapted to slide in the tubular guide und prevented from rotation therein, and turn-buckle connecting; the runner with tho main beam and serving;q for adjustment o theA runner higher or lower, as shown and described.
