My invention relates to hose clamps and among
the objects of my invention are:
First, to provide a hose. clamp which insures
'uniform vconstricting pressure about the bore
without appreciable pressure components cir;
cumierentially about the hose, so that no part
of the hose wall is under circumferential tension;
Second, to provide a hose clamp which, by rea
son of the uniform radial compression on the
hose, is inherently satisfactory even after the
hose has deteriorated by reason of extreme con
ditions of temperature and'humidity;
Third, to provide a hose clamp which requires

One end of thecon
stricting band is provided with a loop 5 through
which extends transversely an anchor pin

In the structure shown in Figures l., and 2,
one of the shoes i is provided with a pair of
radially outwardly extending anchor bosses ii at
the sides of the shoe, defining there between a
slotl adapted to receive the loop â or the con
stricting band. Holes are provided in the Vbosses
il to receive the ends of the anchor pin t. iThe
other end of the constricting band t is provided
with a threaded stem i2 welded or otherwise
secured thereto and which extends substantially
tangentally. The shoe carrying the anchor
