Title: Improvements in or relating to the manufacture of helical lock seam pipe
IPC: B21C37/12
Filed: 1936-09-29
Abstract: 482,413. Making tubes. WILLIAMS, W. P. (American Rolling Mill Co.) Sept. 29, 1936, No. 13998/37. Divided out of 473,800. [Classes 83 (ii) and 83 (iv)] In forming a helical seamed tube, a strip, pulled through the machine, is corrugated and flanged, wound into a helix with the flanged edges interlocked, and the seam is then flattened. The strip is fed between driven corrugating rollers which also flange and bead the edge. It then passes between a mandrel on a turntable and helical rods which force the strip into helical form with the flange and the bead interlocked. Helically arranged rollers then bead over and flatten the seam. In the apparatus shown in Fig. 2 rollers R driven by an electromotor 125 gradually corrugate the strip from the centre, members M forming U and L flanges. The strip is then received between a mandrel 106 and helical rods 108 on a base mounted on a turntable 168 adjustable about pivots 114. Guides 107 position the strip edges. Rollers 23 on the mandrel co-operate with rollers 121, 122, 123, 134 on the turntable to engage and flatten the seam. The rollers 121 are mounted on adjustable spring arms which allow them to follow the seam. The rollers 122, 123 have a slightly flexible mounting and the rollers 124 may be rigid. The rollers 123 are adjustably mounted in respect of pipe diameter and angle of helix. The roller 124 is rotated by an electromotor 113 to pull the strip through the coiling mechanism and co-operates with a roller on the mandrel to flatten the joint. In a modification the electromotor is replaced by an air turbine. In a further modification, all the rollers are mounted on a carriage which wanders to compensate for varying location of the seam. The work may be lubricated by a flexible roller and a wick. Specification 473,800 is referred to.

Filed: 1947-05-27
Abstract: 644,026. Maps. COKER, A. W. May 27, 1947, No. 14115. [Class 146 (ii)] A device for giving a planar representation of the terrestrial globe comprises a map movable past a mask having a circular orifice therein, the map representing the globe by a projection wherein the equator is shown by a straight line 2, latitude lines by equally-spaced lines 4 parallel to the equator, and the meridians by semi-circles 3 of the same radius as the aperture with their centres equally spaced along the equator, the map being positioned so that the equator line passes through the centre of the aperture. In one form, Fig. 1, the sheet on which the map is represented, is cut away along one extreme meridian 4a and at the other extreme meridian has a plain margin 5 which is secured by adhesive to the other end to form a continuous band. The band is stretched over spindles 7, Fig. 2, carried by partitions 11 in a shallow box-like casing with the circular aperture 17 in its upper face 16, the aperture diameter being approximately equal to half the length of the band. The partitions 11 are inclined to the box sides 10 at angle equal to the obliquity of the ecliptic. A representation 19 of a stand may be provided on the face 16. When the spindles 7 are rotated by knobs 14, the effect of a rotary globe is obtained. One of the spindles may be urged away from the other spindle by springs or each spindle may consist of a thin rod with sprocket wheels engaging perforations in the map edges. An aperture may also be provided in the lower face of the casing. In another form, Fig. 7, the map 22 has plain ends and is passed around a card 24 and the ends secured by adhesive, projections 25 on the card serving to retain it. A strip 27 is attached to the plain portions of the map and the whole is then placed in an openended envelope with a circular aperture as before so that the map can be pulled around the card and past the aperture by means of the ends of the strip 27. In this form, parts of the map at one end may be repeated at the other end. According to a modification, a map projection of a complete globe may be mounted on each side of a card which is slidable through an openended envelope with an aperture on each face. The maps are so positioned relatively to one another that the part exposed on one side is displaced 180 degrees from that on the other side.
