Starting from the ``Bonnor rocket'' type solutions [\textit{W. B. Bonnor}, Classical Quantum Gravity 13, No. 2, 277--282 (1996; Zbl 0845.53061)], through a limiting procedure, a metric is constructed that corresponds to a Schwarzschild black hole with a conical defect representing a cosmic string. It is shown that the solution has a novel stress energy source that implies a momentum flux through the string leading to the acceleration of the black hole.
