Application led May 11,190@l Serial No. 316,419.

' Be it known that we, ALONZO LUTHER BAKER. and RUSSELL LOONIE BAKER, cit1 zens of the United States, residing at Altoona, inthe county of EtoWah and State of 4Alabama,.have invented a new `and useful Gultivator, of which the following is a speciication.

aOur invention relates to cultivators; ,and

it has fori-one of its obects' the provision of a simple device vof'this c easily adjusted and in which the breakage of theculti'vator-teeth is reduced to a-minimum.

, tector which 'may be readily-a .A further object of,our invention istue aracter which may be provision of an improved fender or lantrouste to allow as little or as muchear a esired to be thrown about theplantsbeing cultivated.`

' With these and other objects in view, as will hereinafter appear, :ourv invention consists-0f the parts, improvements, and Vcombinations ofparts hereinafter set forth and ointed out in the claims, it being understood,

owever, that variousy changesA in the form,

proportion, and assemblage of partsl may be',

resorted to within the scope of the claims without departing from the principle of our invention or sacriicing any of its advantages. In .this specification and in the drawings, forming a part thereof, the same. reference characters are used to designate the same parts throughout.

In thel drawings, Figure 1 is a side elevational view of one form of cultivator embodying our invention.. Fig. 2 is a bottom plan view of a slightly-modified construction. Fig. 2 is a sectional detail on line 2 2, Fig. 2.` Fig. 3 is a rear elevation ofthe cultivator shown in Fig. 1. Fig. 4 is a central vertical section through a portion of the cultivator shown in Figs. 1 and 3. Fig. 5 is acrosssectional view on the line 5 5, Fig. 4; and

Fig-..6 is a cross-sectional view on the line 6 6,

Fig. 4.

Reference-numeral 1, indicates the beam of the cultivator, to which are bolted ro otherwise secured the handles 2. Beneath the beam 1, and preferably somewhat to the rear of its middle, is secured the brace-ring 3,

lthe beam being recessed to allow receiving the brace-ring, and thereby its lower surface to be iiush with the lower surface of the beam A number of holes 4 are provided in the ring 3V to permit the adjustment of the bars 5, 6, 7, 8, 9, and 10, whichcariythdtivator-teeth 1 1. zWe preferably cause the bars 5 and', to lie in the same horizontal plane by offsetting one end-'ofone of the bars and bolting their inner; ends with a single bolt tothe beam 1. As shown lin the drawings, this' result is secured by makingl the bar 5 straight and by ois'etting the bar 6 at its inner end where it crosses the bar15, as shown. The upper rear ybars 7 and A8 are made to lie in the same plane with o'ne another and with bars 5 and 6 by a similar construction, the bar 7'being straight ahdthe end ofthe bar 8 being oset,

.as .shOWIi Bliatlr` ars 7 and 8 we provide additional strengthening-bars Q ,and 10, the bar Q'beingpfset whereitcrosses bar 10. The bars'7 and 8v are fastened to the beam Vby a single'bolt, the head o'f which is vsunk into a recess in the bar'7. The cultivator-teeth 11 are bolted tothe bars 5 and 6-by bolts 12, the boltslbeingplace'd With their tapped ends uperlnost,`fso that shoulda nut work loose it will be readilynoticed, fandwhen any adyustnine-nt, 2of the device is made the nuts wi l be rea-dil accessible. Especial attention is directe to they fact that our cultivator is so constructed that every bolt "in the framework may, thus be placed with its tav ped end uppermostfa construction which re uces the danger of breakage-because of the nuts Working loose and which-makes our device readilyA accessible by adjustment".l `The 'cultivatorteeth 1 1 are not perforated for the passage of bolts through bars 7, 8, 9, and 10, since we have found that such a construction makes the teeth very liable to break. To remedy this def-ect, we provide depressions 13 in the teeth 1 l, as by stamping t em therein before tempering, and also'provide corresponding projections on the lower rear bars 9 and 10,' Y

which fit snugly into the depressions the cultivator-teeth. This construction makes a strong joint and dispenses with any necessity ofnbreaking the fiber either of the teeth 11 or of the bars r9Y and 10 by making holes therein.

Bolts 14 are passed through the bars 7, 8, S), and 10, respectively, to secure them together. Between the said bars there are only the teeth 11 to hold the bars apart, so that it 1s possible to secure the teeth therebetween as tightly as is desired. On the inner bolts IOO tector or fender 16.

` protect` the planls from falling dirt.

14 on each side of the beam are bolted braces 15, the opposite ends of the bracesl beiner secured to the beam 1 on -top thereof 4ind by .the same bolt which secures the bers 7 and S thereto. The bolts 14, securing the bars and 10 to the braces 15, also pass through` Immediately benenth the bezinixl w'li'en the device 1s used, for example, :is :i Inirrow, es shown in Fig. 2, we provide n tooth ll, which is secured to its place in the humm-r already described. Then cultivating zi roA 'of plants, we substitute therefor u plaint pro- Tosupport the .mid fender, e short metal bor 17 is secured to the. cnltivatordrzmie in the suine way s :i re the teeth 11. The ber 17 projects downwzirdlv at its rear end and has pivoted on said downwardly-projecting end the top ber 18 of the fender. To the said top bor 18 are seeured the guard-blades. l l) by means of short crossburs 20. These guind-bhules :ire designed to pass on each side of4 :i row of phints and to To zul just the fender 16', we provide a. slott'odyoke 21, which is :idjustably secured to the cross bar of the lunidles 2 by n. thumb-serew"\22.

A link 2% is secured at one' end to the fender, end its opposite end passes' throughfan'open` mg 1n the yoke 2 1 and is heeded upon the extreme end. By this inerins we :ire itble to set thel fender so tha-t it cannot fell below o. predetermined position and yet een rise reedily to pass over obstacles.
