Divided and this application filed July 16, 1908.
Serial No. 443,897.
To all 107mm. it may concern:
Be it known that we, ALoNzo 1i. BAKER, of Herndon, Madera county, California, and HUssnLL L. BAKER, of Joppa, (lulhnan county, Alabama, both citizens of the United States, have invented a new and useful (ul tivator, of which the following is a specification.
This invention relates to cultivator-s and is a division of an application filed May 11, 1906, Serial No. 316,419, said application having issued as Patent No. SSS .660, of Oct. 16, 1906.
The object of the invention is to provide a device of this character utilizing spring teeth which may be easily adjusted and which are so arranged as to reduce breakage to the minimum.
A further object is to provide simple and efficient means for holding the teeth in adj usted positions without the necessity of perforating them so as to permit the passage of the securing bolts ordinarily employed, and which obviously weakens the teeth to a considerable extent.
With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.
In the accompanying drawings is shown the preferred form of the invention.
In said drawings: Figure 1 is a side elevation of the cultivator. Fig. 2 is a bottom plan view thereof. Fig. 3 is an enlarged section on line AB, Fig. 2. Fig. 4 is a rear elevation. Fig. 5 is a central vertical section through a portion of the cultivator. Fig. 6 is a section on line CD, Fig. 5. Fig. 7 is a section on line E F, Fig. 5.
Beneath bars 7 and 8 we provide additional strengthening bars 9 and 10 the bar 9 being oilset where it crosses bar 10. The bars 7 and S are fastened to the beam by a single bolt, the head of which is sunk into a recess in the bar 7.
The cultivator teeth 11 are bolted to the bars 5 and 6 by bolts 12, the bolts being placed with their tapped ends uppermost so that should a nut work loose it will be readily noticed and when any adjustment of the device is made the nuts will be readily accessible. Especial attention is directed to the fact that our cultivator is so constructed that every bolt in the frame work may thus be placed with its tapped end uppermost a construction which reduces the danger of breakage because of the nuts working loose and which makes our device readily accessible by adjustment.
The cultivator teeth 11. are not perforated for the passage of bolts through bars 7, S, 9, and 10 since we have found that such a construction makes the teeth very liable to break. To remedy this defect we provide depressions 13 in the teeth 1] as by stamping them therein before tempering and also provide corresponding projections on. the lower rear bars 9 and 10 which iit snugly into the depressions in the cultivator teeth. This construction makes a strong joint and dis penses with any necessity of breaking the fiber either of the teeth 11 or of the bars 9 and 10 by making holes therein.
Bolts 14: are passed through the bars 7, S, 9 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 is possible to secure the teeth thcrebetween as tightly as is desired. Braces 15 are arranged at opposite sides of the beam and are secured at one end to the inner bolts 14, the other ends of the braces being secured to the lie in the same horizontal plane by offsetting beam 1 on top thereof and by the same bolt one end of one of the bars and bolting their l which secures the bars 7 and S thereto.
