I think what you want are velocities (see 12.8 on page 120 of (1)). 
Iterated tangent bundles have lots of repetitions of the lower order parts. They and velocities are special cases of Weil bundles as treated in chapter VIII of (1). The infinite dimensional version of Weil bundles is treated in section 31 of (2).
