Hedeman 2,260,454 Oct. 28, 1941
Wehringer 2,319,024 May

Metcalfe et al. 4,293,147 Oct. 6,

(Metcalfe)
Claims 2 to 4 and 8 to 12 stand finally rejected under
35 U.S.C. § 103(a) as unpatentable over Hedeman in view of
Thompson and either of Wehringer or Metcalfe.
Hedeman discloses a pipe (hose) to coupling (nipple)
joint in which an end (insert) of the coupling, having a ridge
16 at its end and circumferential projections 17 on its
exterior, is inserted into the end of the pipe and a clamp 18
is positioned around the pipe, pressing it against the insert.
Hedeman's disclosure concerning the clamp is (col. 2, lines 26
to 33):
The numeral 18 designates a clamp of any suitable
type for the purpose of pressing the hose against
the annular ridge 16 and assuring the effective
sealing of the connection between the hose and the
nipple. The use of a clamp is not essential but is
desirable where the hose is to be used for
transmitting liquid under substantial pressure.
