Title: Improvements in the manufacture of butt and lap welded tubes
IPC: B21C37/08
Filed: 1926-02-02
Abstract: 263,323. Chisholm, D. W. Feb. 2, 1926. Tubes. - In the manufacture of butt and lap welded tubes by drawing a heated strip through a die, heating the edges by oxygen or other welcling gas, and then welding by rolls, the edges of the strip are positively supported both at the exterior and interior just before entering the rolls so as to prevent buckling &c. when being acted on by the gas. The heated strip C is drawn through the skelping-die A and during its passage to the welding-rolls B its edges are supported at the interior and exterior respectively by a U-shaped tapered mandrel 4 and a detachable guide 10, which is secured by bolts to one face of the die. The mandrel is loosely secured by a bolt 6 and enlarged hole 4<b> to a bar 1 so as to exert a yielding pressure on the interior edges of the strip and at the same time to enable it to accommodate itself to irregularities in the strip. The bar is hinged or loosely supported on a projection 2 from the die and pressed down by adjustable and interchangeable weights D or springs. The mandrel contains a nozzle 15 for the supply of gas from a pipe 14, the gas being deflected by the surface 10<d> of the guide on to the abutting edges C<1> of the strip, which together with the mandrel and guide form a pocket for the gas. The guide consists of a concave bridge 12 and spaced vertical jaws 11, all of which are of converging shape. The bridge piece is chamfered and rounded at 12<a> to fit closely to the groove in the lower roll and the edges 11<a> of the jaws 11 are of concave tapering shape to correspond with the contiguous surfaces B' of the rolls. The mandrel is spaced from the guide by a pair of projecting pins 16. A mandrel 7 with convex lower surface is rigidly secured to the bar 1 against a stop 9, to co-operate with the welding-rolls. In a modification, Fig. 6, a mandrel 17 is secured by a bolt 18 in a recess 19<b> in a hinged bar 19, the toe piece 17<a> serving as the welding-mandrel. Gas is supplied to the nozzle 20 from a pipe 21. The Provisional Specification refers to Specification 243,858.

Filed: 1919-02-12
Abstract: 139,278. Wilson, S. C. Feb. 12, 1919. Reciprocating shelves.-An apparatus for drying wool by the circulation of hot air consists of a closed chamber wherein means are provided to cause wool to be carried forward over the perforated surface of a series of travs which are reciprocated horizontally. The chamber enclosing the trays has a layer of insulating-material C<4>, Fig. 1, built into its walls and roof. The perforated trays A, arranged in a tier and secured together, are supported on small runners D carried by an angle-iron framing B built up within the chamber. A rack-bar E secured to the trays gears with a wheel E<2> secured to a shaft E<3>, and a similar wheel secured to the shaft is alternately engaged by two segmental toothed wheels F, F'. Thus the rotation of the segments, which are geared together, imparts a reciprocating movement to the rack-bar E and therefore to the trays. The wool is fed on to the uppermost tray from a shoot C<2> by a shoot-plate J hinged at J<1> to the tray and vibrated by small cams on a rotating shaft J<2>. Delivery shoots G hinged to the trays convey the wool from one tray to another. The means for moving the wool along the surface of the trays consists of rollers H provided with radial or tangential fins h<1>, as shown in Fig. 9, and supported by the framing above the trays. The rollers are rotated, as the trays move forwards, by racks attached to the trays, but are prevented from rotating as the trays move backwards. Thus they bold the wool as the trays move backwards, and therefore push it towards the discharge ends of the trays.
