Abstract

1448842 Pipe couplings CATERPILLAR TRACTOR CO 24 Aug 1973 [25 Aug 1972] 07264/76 Divided out of 1448841 Heading F2G [Also in Division E1] A coupling 134 for connecting a hose end 130 to a member 50 having a passage, comprises a bolt 138 screw threadedly connected to the member 50 and having a longitudinal passage 140 communicating with the member passage and at least one radial passage 148 communicating with the longitudinal passage 140. A tubular coupling body 142 is disposed about the bolt 138 with part of its inner surface in slidable contact with part of the outer surface of the bolt 138, the coupling body 142 having a lateral passage 144 and being adapted to receive the hose 130 which communicates with the passage 144. An annular passage 146 is defined between the inner surface of the coupling body 142 and the outer surface of the bolt 138 to provide continuous communication therethrough between the coupling body passage 144 the bolt radial passage(s) 148 whilst allowing movement of the coupling body 142 about the longitudinal axis of the bolt. The annular passage may comprise an annular groove 150 formed in the inner surface of the coupling body 142. The coupling 134 is used to connect a hose extending from an arm, to a hydraulic cylinder, in order to operate an implement, e.g. a bucket, pivotally mounted on the arm.
