SPECIFICATION forming part of Letters Patent No. 282,852, dated August '7, 1883.
' Application filed January @1888. (N0 model.)
To all whom it may concern/.-
Be it known that I, WILLIAM J. DAVIDSON, of Big Spring, Montgomery county, Virginia, have invented certain Improvements in Oultivators, of which the following is a specification.
The object of my invention is to reduce the strain upon the bolts connecting plow-standards to brackets or to the beam-similar, for
instance, to those standards shown in my Patent No. 265,7 63-and also to avoid injury to any part of the plow from an unyielding connection of the standard thereto; and to these ends my invention consists in the improved construction, fully described hereinafter.
In the drawings, Figure 1 represents. in perspective a section of a plow-beam provided with a bracket having secured thereto a standard and illustrating my improvement,
purpose of this arrangement is to lock the standard in any position to which it is adjusted. In the aforesaid patent the slot 0 of the standard was referred to and illustrated as of uniform width 5 but in practice I have found that there is sometimes a tendency of the bolt to slip, a difficulty which I overcome by forming the slot with a serrated or roughened side, as shown. In the said patent the retaining- I bolt i s described as passing through a per foration in the curved portion of the standard, so'that the standard is held immovably by the bolt, this subjecting both the bolt and standard at times to great strains. I avoid this straining of the parts by providing the standard with a notch, f, which receives the bolt 9, whereby the standard is retained in place so long as there is no excessive pressure; but when the share strikes an obstruction the shock of the contact will lift the standard off of the bolt 9 and prevent any straining or breaking of the parts.
The curved standard (J, formed with an inclined elongated serrated slot, 0, at one end, and an upwardly-extending notch, f, in its inside face, in combination with the plow-beam, slot Witnesses:
