Abstract

532,598. Making gilled pipes. RAMBUSH, N. E., and DEAN, J. O. Sept. 11, 1939, No. 25519. [Classes 83 (ii) and 83 (iv)] Tube expanders.-Gilled tubes are made by assembling a number of rings or a helix on the tube and driving through the tube a loose tablet or block of greater diameter than the tube so as to expand the tube into tight engagement with the gills. The gills 1 are placed in slits 2 on a cage 3 and the tube 4 inserted with its end 5 in a recess 6 on a headstock 7 to form a stop to the end of the tube. The other end of the tube is expanded and a loose block 10 with an hydraulic cup leather is inserted. An hydraulic piston 15 provided with a sleeve 8, an hydraulic seal 9 and a valve 17 carried by spring-loaded perforated plate 10, is then pushed forward by fluid pressure. When the plate 10 engages the end of the tube the valve 17 is opened and the block driven through the tube by fluid pressure so as to expand it. The headstock 7 has a rubber cushion 18 to deaden the impact of the block and an opening at the bottom for the recovery thereof. Instead of driving the block 16 by hydraulic pressure it may be displaced by mechanical means such as a screw ram.
