pieces are controlled by springs and are pivoted at one end. The pin is provided
with a ward or wards. The other piece carries two bolts having inclined ends &
notches which engage with the catch pieces aforesaid. By passing the bolts
through the links of a cycle chain & then engaging the ends of the said bolts
