[No. 88

compound outlet-tube B1 inserted into the valve-casing. Air
is forced from the inflator-pump through the air-inlet tube
and into the air-space D. The air forces the compound
downwards, and it escapes by passing through the compound
outlet-hole B and tube B1 into the air-tube of a bicycle-tire.
When the requisite amount has been introduced therein the
valve is replaced into the tire, which is inflated in the ordi-
nary way.
