Definitions

  • the present invention relates to an arrangement for the hydraulic operation of ships hatches by means of piston servomotors, which can be used even for single folding hatches without subjecting the deck to heavy local loads from the servomotors beyond the weight of the hatches themselves.
  • the arrangement according to the invention consists of piston servomotors which are so disposed as to operate by one end a hatch mounted pivotably about an axis parallel to the deck, acting thereon at a distance from the said axis, and is characterised in that the other end of the servomotor is pivotally fastened to a hinge pin which is parallel to the said axis and which is mounted on the free end of an arm which by its other end is held fast in a parallel-sided block which in a manner known per se is mounted to be non-rotatable but vertically slidable between vertical guide bars secured to the deck, the said parallel-sided block carrying the hatch spindle so that the deck is not subjected to any local load from the servomotor beyond the weight of the hatch transmitted through the parallel-sided block or blocks.
  • FIGURE 1 shows a form of construction of an arrangement according to the invention, viewed from the side,
  • FIGURE 2 shows a detail of the articulation in section
  • FIGURE 3 shows the parallel-sided block and its guide bars viewed in the direction of the hatch spindle.
  • a ships hatch 1 is pivotally mounted on a spindle 2 which is non-rotatably fastened in parallel-sided blocks 3 which are mounted to be non-rotatable but vertically slidable between vertical guidebars 5 fastened to the deck 4.
  • the spindle 2 is provided with a non-rotatable projecting arm 6 which is advantageously directed obliquely downwards.
  • a pivot pin 8 parallel to and spaced from said spindle.
  • a hydraulic piston and cylinder servomotor 7 is pivoted on this pin 8 by its piston rod, and its other end, i.e. the cylinder, is pivotally secured to hatch cover 1 at a point spaced from spindle 2.
  • This floating pivot 2 may be inexpensively installed, as it is not necessary that the pivot 2 be accurately located with respect to the plane of the top of the hatch coaming as a fixed pivot would need to be and, also,
  • the thickness of the gasket material becomes immaterial, as the spacing between the coaming and cover adjusts itself according to the thickness of the gasket material.
  • Operating means for a movable cover member of a hatchway or the like in a deck of a ship including: a spindle member mounted in non-rotatable and vertically slidable manner to one side of and beyond the area of said opening, said cover member being pivoted on said spindle for pivoting between a closed position in which it closes said opening and an open position in which it is tilted away from said opening; an arm member fixedly secured to said non-rotatable spindle member and extending at an angle to said closed position of said cover member; and an extensible member having a first end pivotally coupled to said arm member and having its other end pivotally coupled to said cover member at points spaced from said spindle whereby, upon extending said extensible member, said cover will be raised.
  • Operating means for a movable top cover of a horizontal opening including: vertical guide means fixedly mounted beyond the area of said opening; a slide member mounted in said guide means to be vertically slidable and nonrotatable therein; a horizontal spindle member fast with said slide member, said cover member being pivotally mounted on said spindle member for pivoting between a closed horizontal position in which it closes said opening and a vertical open position in which it is raised from said opening; an arm member fast with said spindle member and depending therefrom; and jacking means having a first end pivotally connected to said cover member and a second end pivotally connected to said arm member, at points spaced from said spindle member.
  • Operating means for opening and closing a hatch cover of a hatchway in a ships deck including: a horizontal spindle, said hatch cover being freely rotatable on said spindle; an arm fast with said spindle and depending obliquely therefrom in a direction towards said hatchway, said arm having a lower end disposed at a level below said spindle and between said spindle and said hatchway; a pivot pin secured on said lower end, said pin being parallel to said spindle; an extensible jacking device pivoted at one end on said pivot pin and pivotally connected at its other end to said hatch cover, said other end being spaced from said spindle, and at least one parallel-sided slide member fast with said spindle; for each slide member a guide member fixed outside said hatchway, said guide member having parallel vertical guide surfaces slidably engaging the parallel sides of said slide member for guiding the latter for vertical movement while preventing rotation of the same whereby, when said hatch cover is in closed position, said spindle adjusts itself vertically so that the hatch cover seats face
  • operating means for said hatch covers comprising: at least one horizontal spindle disposed outside said coaming, said hatch cover being rotatable on said spindle; a lever arm fast with said spindle and depending therefrom obliquely towards said hatchway; a pivot pin on said arm, said pin being spaced from and parallel to said spindle; an
  • extensible hydraulically operated piston and cylinder servomotor having one end mounted on said pin and its other end pivotally connected to said cover at a point spaced from said spindle; a slide block having parallel vertical sides in planes transverse to said spindle; secured to each end of said spindle parallel vertical guides for each said slide block fast with said deck and engaging said sides of said slide blocks, said slide blocks being vertically slidable and non-rotatable in said guides, where- 10 by said hatch cover will be pivotally secured for opening and closing on a floating spindle to accommodate variations of gasket thickness.
