  We construct new smallest parts partition functions and smallest parts crank
functions by considering variations of Bailey's Lemma and conjugate Bailey
pairs. The functions we introduce satisfy simple linear congruences modulo $3$
and $5$. We introduce and give identities for two four variable
$q$-hypergeometric functions; these functions specialize to some of our new
spt-crank-type functions as well as many known spt-crank-type functions.
