lliwell gives one in his Dictionary of the passive participle, which see. In Shakspeare it occurs as a neuter verb:
"... And teach this body, To bend, and these my aged knees to buckle, In adoration and just worship to you." Ben Jonson, Staple of News, Act II. Sc. 1.
"For, certainly, like as great stature in a natural body is some advantage in youth, but is but burden in age: so it is with great territory, which, when a state beginneth to decline, doth make it stoop and buckle so much the faster."--Lord Bacon, "Of the True Greatness of Great Britain," vol. i. p. 504. (Bohn's edition of the Works).
And again, as a transitive verb:
"Sear trees, standing or felled, belong to the lessee, and you have a special replication in the book of 44 E. III., that the wind did but rend them and buckle them."--Case of Impeachment of Waste, vol. i. p. 620.
