Definitions

  • This invention relates to a simple and practical method and apparatus for cutting or punch ing sheet or plate material, usually of a ferrous character such as iron or steel.
  • One of the objects of the present invention is to provide an improved relatively small, compact and self-contained article especially adapted for cutting or punching holes in sheet metal.
  • a further object is to provide an article of the above character which may be inexpensively manufactured and assembled, andwhich will be reliable and safein use and operation in proper hands.
  • a further object is to provide an article of the above character requiring little or no external means for operating the same at the place desired.
  • a further object is to provide an improved method of quickly cutting or punching holes in sheet metal or the like.
  • Fig. 1 is a semi-diagrammatic perspective view of the device in operative position upon a sheet of material to be punched;
  • Fig. 2 is a vertical longitudinal sectional view of the complete device
  • Fig. 3 is a sectional plan view taken substantially on the line 3-3 of Fig. 2 with. parts removed for the sake of clearness.
  • 5 indicates diagrammatically a sheet of material through which a hole is to be punched or cut by means of the device shown positioned thereon or in section in Fig. 2.
  • This device comprises a con- 7 tainer 6 which, for cheapness and simplicity of manufacture, is preferably made cylindrical in form with a substantially smooth unobstructed inner surface, having a height slightly greater than its diameter. While shown. cylindrical, it of course could be a polygon of any desired number of sides, but such construction is less desirable because of the dimculty of manufacture.
  • a guide member I Centrally disposed within this cylinder is a guide member I which may be a solid bar or a tube as desired, which is concentrically disposed with relation to the container 5 and is for the purpose of positioning and guiding a cutter or punch 8.
  • This cutter or punch as herein shown is annular in plan view and V-shaped on any radius,- the open part of the v facing downwardly with relation to the other parts when in the position shown in Figs. 1 or 2.
  • This cutter or punch 8 is of any suitable metal, and may be mild steel, which may be easily and quickly deformed and collapsed under'the tremendous pressure, heat and action of the explosive indicated at H! and positioned in the upper part ofthe container 6.
  • The'explosive which may be of any suitable kind, is preferably a relatively small quantity of TNT, or any other powerful explosive, which is detonated or ignited by any suitable means such as a detonator or cap I
  • detonating herein used in the specification and claims is to be construed broadly as including any means or method of initiating the action of the explosive within the container.
  • the upper and lower ends of the container 6 may be closed, if desired, as by means of thin cover plates l2 and I3. These can be of fiber or very thin sheet metal and are used primarily to protect the explosive against moisture and displacement.
  • the cutter or punch 8 has a frictional fit with respect to the inner wall of the container 6 and the guide 1 and in certain cases may be held in place by its adhesion to the explosive Ill placed thereabove, which in certain cases is melted and either poured in the top, or the container may be inverted and, while the explosive is still in a semi-plastic condition, the cylinder I and cutter 8 may be pressed downwardly into the semi-molten or plastic mass.
  • shear pins or the like such as indicated at 9 may be used in order to prevent relative movement of the parts if handled roughly.
  • This cutter 8 for the size hereinafter described is preferably spaced from the botto T3 of the container 6 a distance substantially equal to the diameter of the case and, being held in position largely by its frictional engagement with its coacting parts, is otherwise free to move. downwardly with respect to the smooth substantially unobstructed inner surface of the container.
  • the explosive charge is detonated
  • the cutter being of concave ring form as herein shown cuts a circular opening in the plate and the central disc falls clear on operation.
  • the cutter is far more effective and efilcient in penetrating qualities than were the explosive force to be applied to a solid punch acting on the entire area of the opening to be out.
  • the cutter 8 should be about four inches from the bottom and will punch an opening or circle through a mild steel plate about inch in thickness and about 4% inches in diameter. Accordingly, the size of the container may be selected according to the thickness of the plate and the hole to be punched.
  • amount of explosive may be varied as desired.
  • the present device is directed to a complete, compact and self-contained mechanism which may be easily and quickly conveyed, placed or positioned with respect to the plate to be perforated and actuated to accomplish the penetration, all in a very short space of time.
  • the action of the device- is limited to a very specific zone of the obstacle.
  • a building may be on fire and sections of the building protected from other sections by means of flat steel firedoors either in the walls or floor which are possibly locked. or otherwise secured against movement.
  • one of these small, portable, self-contained mechanisms may be placed against the sheet material to be perforated and ignited by a fuse, detonator or even a flashlight battery I5, to almost instantly cut or punch the desired hole'thro-ugh the door or floor, after which a hose could Ire inserted through the opening and the desired results accomplished.
  • Containers of chemical substances can also be pushed or projected through the aperture thus produced.
  • the present invention contemplates a simple and practical mechanism as well as a. method for quickly cutting or punching holes through sheet material and is well adapted to accomplish, among others, all of the objects and advantages herein set forth.
  • a device a set forth in claim 12 in which the cutter is of ring form thereby to make a circular cutting with a central solid disc.
  • the herein described method of cutting or punching out a disc in sheet metal or the like comprising the steps of positioning a. container having an explosive'and a collapsible inverted concave cutter ring adjacent the plate to be cut with the cutter ring freely spaced a material distance therefrom, and detonating the explosive to collapse the ring and fuse the sides of the concave cutter ring by the heat of explosion into one substantially solid mass to drive the ring through the plate and to cut a disc out of the plate.
