Definitions

  • JOHN HANsoN of Huddersfield, in the county of York, in England, leaden-pipe manufacturer, and, CHARLES HaNsoN, of the sam-e place, watchinaker, being respectively subjects of the Queen of Great England, have invented certain new and useful Improvements in Machinery or Apparatus for Making or Manufacturing Pipes and Tubes fromV Metallic Substances; and we, the said JOHN HANsoN and CHARLES HANSON, do hereby declare that the nature of our said invention and the manner in which the same is to be performed are particularly described and ascertained in and by the following description th-ereof, reference being had to the drawings hereunto annexed, numbered, respectively, Sheet 1 and Sheet 2, and to the letters and figures marked thereon-that is to say:
  • XVe use an improved mode of arranging and adjusting the dies or apertures which determine the outer diameter of the pipes or tubes, by which we are enabled easily and readily to bring the same central with the core when applying a fresh set of dies and cores to the cylinders in order to make pipes of different sizes, or at any time in case the same should get out of their relative true positions from any other cause.
  • Ne employ a fixed guide piece, crossbar, plate, holder or bridge placed near to the dies or apertures at the end of the cylinder, for the purpose of receiving and holding the short xed or stationary core.
  • le sometimes use a long movable core, attached to the piston, resembling that of Thomas Burr, and in this case we employ the fixed guide piece or bridge for the purpose of guiding and conducting the long movable core and keeping it central with the dies; the said movable core passing through the guide piece, cross-bar or bridge.
  • the chamber (X Figures l and 21, on Sheet 1) situated between the bridge or holder, and the die, is formed of a. conical form a support to the cross bar, guide piece,
  • Fig'. 1, Sheet 1 is a vertical section of the lower portion of a cylinder with the piston just below the cross bar, for the purpose of showing the die more clearly.
  • Fig. 4: is a plan view of the diedetached showing the situation of the core within the aperture.
  • Fig. 5 is a detached side view of the short fixed core and its cross bar or bridge, and
  • Fig. 6 is a plan viewof the same.
  • A, A, Fig. l is a portion of the cylinder; B, the piston rod or plunger, which is fixed or stationary in the head of the strong frame work of the apparatus.
  • C is the piston attached to the plunger or rod, the various parts or details of which are shown separate at Figs. 13 to 18 inclusive, and will be described hereafter.
  • D is the lower end or bottom of the cylinder firmly attached thereto by bolts, and also to a strong hollow pillar, table or platform placed on the top of the usual ram of the hydraulic press.
  • E is the die, which is fitted into the bottom of the cylinder in a recess or cup, as shown in the drawings.
  • F, F are adjusting screws for setting, or regulating the situation of the die as regards the core.
  • Gr is a thin steel plate fitted very accurately into a cup or recess in the bottom of the cylinder for the purpose of preventing the lead or other set metal from being driven between the edges of the die and the recess or to the adjusting screws, the threads of which would otherwise become clogged. It is exhibited in several of the drawings. But as a substitute for the steel plate G, we prefer to employ the steel ring Z, which forms the conical chamber, and is employed and exhibited in Figs. 1 and 20. Sheet 1. The diameter of the aperture through the steel ring Z is greatest at the edge or side next '1 to the bridge or holder, and diminishing downward it is smallest at the end next to the dies.
  • Fig. 20 is a view of a section of the steel ring Z.
  • Fig. 21 is a sectional representation (on another scale) of the conical chamber X, formed by the steel ring Z, with the die E below, and
  • the steel ring Z, forming the conical chamber has the advantage over the steel plate Gr, of constructing the metal inits.
  • FIG. 7 is another vertical section of the lower part of a cylinder, showing a novel arrangement combination and adaptation of our improved mechanism for making four different lengths of pipes at one and the same time.
  • Fig. 8 is a partial sectional plan View of the same, taken in the line g, h, in Fig. 7 Fig. 9 is a horizontal section or plan View taken at the line e, f, the plate H being removed.
  • Fig. 10 is another horizontal section t-aken through the dies and cores in the line a, b, in Fig. 7.
  • Fig. 11, is a plan view of the bottom of the cylinder, the dies and cores being removed to show its construction.
  • Fig. 12 is a side View of one of the cores detached.
  • A, A is the cylinder; B, B, the bottom of the same;
  • C, C are the dies the cores and apertures of which are in this instance placed in a horizontal position.
  • D, D are the screws for properly adjusting the horizontal situation of the dies as regards the cores or mandrels and E, uE, are wedges for adjusting the vertical position of the dies to the cores.
  • F, F are the cores or mandrels fixed into a forming part ot stocks or pieces of metal, G, G, which are mortised into one another, and also into the bottom of the cylinder as shown in the drawings and thereby securely retained in their proper situation.
  • the arrows indicate the course of the metal as it passes out of the cylinder in the form of tubes or pipes which is shown by a red tint as in the former figures.
  • H is the thin steel plate (here used instead of the steel ring) having four apertures formed in it corresponding with the wells and recesses formed in the bottom of the cylinder, which steel plate is placed on the top of the dies to prevent the access of set metal to the adjusting screws, and I, I, are other plates placed in front of the dies for the same purpose and to prevent its access to the wedges.
  • the bottom of the cylinder has four wells ⁇ diately underthe piston.
  • Fig. 13, Sheet 1 is a representation of the end of the piston rod, shown detached from the cylinder with our improved construction of piston attached thereto.
  • Fig. 14 is a similar representation with the parts of the piston detached, which are shown separateV at Figs. 15, 16, 17 and 18.
  • a is the piston rod; is the lower end or butt of the piston attached -to the rod by the pin c; l is the upper part of the piston.
  • ring e Between the inclined or conical shaped sides of the parts d and Z) is placed the ring e,- shown detached in plan at Fig. 17, and in section at Fig.
  • this ring are also inclined or conical shaped, and it is cut or severed by means of a saw in the direction shown by the line f, g., in Fig. 1S, and consequently it will be obliged to expand and keep the piston tight-ly packed with the cylinder under great pressure and thereby prevent the escape of metal past the piston.
  • the piston is attached to its rod' a by means of a pin z, passed through it, and the pin 0, or in any other convenient manner.
  • Fig. 19 is a vertical section of a cylinder and piston, showing our last improvement applied thereto, (viz.) the application and adaptation of t-he guide piece, or crossbar, plate or bridge, through which the long core or mandrel attached to the piston passes, for the purpose of keeping it central with the die.
  • A, A is the cylinder.
  • B the piston rod.
  • C the piston.
  • D the bottom of the cylinder.
  • E the die.
  • G the thin steel plate, (here exhibited rinstead of the steel ring that in Figs. 1 and 21 form t-he conical chamber.)
  • F the adjusting screws.
  • H the long core attached to thepiston C and traveling with it passing freely through the guide piece, cross bar lor bridge I, I, which has a properly shaped hole bored through it for this purpose consequently keeping the core at all times steady and central with the die.
  • K is the aperture for supplying the cylinder wit-h melted metal.
  • Sheet 2 exhibits the reversed arrangement of the cylinder A, and the piston B.
  • L is the table.
  • M the top of the hydraulic press.
  • N shows the situation of the ram.
  • the power of the hy- ⁇ draulic press is set 1n action, and as the ram, hollow pillar, table, cylinder with its appurtenances rise upward, the feeding aperture is first closed by the stationary pis- Wound upon reels, as fast as it is discharged y from the machinery.
