Abstract

13,611. Davis, G., Davis, W., and Davis, S., [trading as Marshall Bros.]. June 10. Stopping pipes.-A drain-pipe stopper for use in testing &c. comprises an annular inflatable bag A, of the form shown, mounted between disks B, C held in place on a central tube D by nuts F, G the latter bearing on a loose sleeve H by which the position of the disk C can be adjusted. The outer end of the central tube D has a double cap I, removable to allow escape of the testing-water &c. The bag A is inflated through a tube 5 with a suitable valve 7.
