Onsetter

The person stationed at the shaft bottom responsible for loading and unloading the winding cage, hooking and unhooking tubs or corves, and signalling up to the surface Banksman — the underground counterpart to the banksman, working the same shaft from the opposite end.

Historical usage

Recorded as historical, dialect vocabulary of Northern England: an onsetter was, in its original sense, 'a worker at the bottom of a mineshaft who exchanges the empty and full corves.' As winding technology and signalling systems developed, the role's core duty stayed constant — controlling cage traffic and signalling at the shaft bottom — while its technology moved from hand-hooked corves to tub and cage systems with coded bell signals.

How it worked

Positioned at the inset or shaft bottom, the onsetter received the descending cage, unhooked or unloaded it, hooked on or loaded whatever was to be raised — tubs, materials, or men — and signalled to the banksman above when the cage was ready to be wound up. In modern mining the same role is typically performed from a fixed cabin with signalling and cage controls close to hand, but the underlying job, controlling shaft-bottom traffic and signalling the surface, is unchanged.

Why it was used

Whoever wound the cage from the surface could not see the shaft bottom, so a reliable, correctly-signalling onsetter was as essential to safe winding as the banksman above — the two formed either end of the same signalling chain, with the winding engineman acting on what both of them told him.

Risks & limitations

The onsetter worked at one of the most dangerous fixed points in the mine, immediately beside an active shaft where a miscue, an overwind or a mechanical failure could kill him along with anyone in the cage; several documented shaft disasters record an onsetter among the dead or among the few who survived a wider catastrophe by chance of position.

Regional variation

Northern England dialect term; the role itself was universal wherever shaft winding was used.

  This disaster's own narrative notes that 'only five survived from the Hutton seam, along with one onsetter' — a direct textual match; manually linked after the automated sweep capped it at the disaster's existing 5-term limit, since Onsetter had zero backlinks anywhere else on the site.
