Abstract

621,254. Pipe joints. AKTIESELSKABET FISKER & NIELSEN. Feb. 11, 1947, No. 3970. Convention date, March 4, 1946. [Class 99(i)] A pipe joint, particularly for vacuum cleaning apparatus, of the kind wherein one end of an inner pipe is adapted for insertion into one end of an outer pipe, has one or both of the pipes provided with one or more resilient tongues adapted to press against the other pipe, each tongue having its longitudinal axis at an angle to the longitudinal axis of the pipes. The tongues provide a firm grip without preventing deliberate disconnection. Fig. 3 shows an outer tube 1 with three rings of tongues 5, two of the rings having tongues with their axes at right angles to the pipe axis while the right-hand ring has the axis of its tongues at acute angles to the pipe axes. The inner pipe may have none, one, or more similar tongues. Fig. 6 shows a joint in which the inner pipe 2 has annular grooves 14 in which the tongues 5 engage so as to lock the joint. In Figs. 7 and 8 the outer pipe is fixed in a suction nozzle 9. The modification shown in Fig. 7 has double tongues formed by making approximately W-shaped cuts in the pipes, whereas that shown in Fig. 8 has the tongues formed at the extremity of the pipe.
