Tilt- an awning, a covering, a tent. First appeared in English writing about 1440 (OED). Just an old word that has gone out of favor. As late as the 1971 edition, it was the first definition discussed in the OED.
It was used in Newfoundland- "They had made a tilte with a sayle..." 1612, Dict. Newfoundland English.
Its use was widespread in the past in the United States and Canada; it is fully defined in Webster's Third New International Dictionary.
Also see medieval German telt, a tent.

Scran for eatables is 18th century or older. (OED)
Bevvy or bev for drink was in use from the 19th century onwards. (OED).
Can't find chat or dodgings in general use, but American carnival-circus people have much cant, little understood by outsiders, and I am sure English workers in those fields have even more.
