Abstract
17,232. Crossley, E. E. W. Feb. 2, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Incrustation, removing; check valves.-The scale which accumulates about the check valve and its seat of a boilerwater feed device, is removed by lifting the valve 4 from its seat and allowing water and steam to rush past it into the inlet passage 8 and out through a valve at the side. The valve 4 is raised by a screw-threaded rod 16 engaging the bifurcated head 13 of a tube 12 and operated by a hand-wheel 17. The tube 12 has an operating arm 15, a screw-threaded part to engage the screw-threaded part 11 of the tubular part 7, and forks to enter between the wings 5 of the check valve to enable it to be turned in contact with its seat so as to remove attached scale.
