Definitions

  • the present invention relates to a system of covers for hatches aboard ships or similar openings, of the type wherein the covers comprise sections provided with wheels for horizontal movement along the hatch coaming and wherein the coaming is provided with rail sections which may be vertically moved for the purpose of lifting/lowering of the cover sections from battening to running position and vice versa.
  • the object of the present invention is a system which ensures simultaneous battening along the entire length of the hatch coaming in a desired time relation to the total vertical movement of the section. According to the invention, this is achieved thereby that each device used for the vertical movements of the cover sections is coupled to a shaft which is rotatably supported along the hatch coaming and extends in the running direction of the cover sections and which is provided with devices for the battening of the cover sections. In this manner a structurally simple device is obtained, which ensures that the battening operation is performed in absolute dependency of the height position of the cover section relatively to the hatch coaming.
  • a structurally very simple and rugged system is obtained when the longitudinally extending shaft is provided with arms, each cooperating with a lifting device for the cover sections, so as to rotate the shaft during vertical movement of the cover sections.
  • the horizontal battening movements in dependency of the rotation of the longitudinally extending shaft may be obtained in any suitable manner, such as by mans of eccentrics, but it is particularly convenient to so form the system that the longitudinally extending shaft is provided with arms each of which is adapted to cooperate with a battening device, for the horizontal movement of the same to and from locking position of the cover sections by rotation of the shaft.
  • the system may be so fon'ned that the turning and battening arms of the longitudinally extending shaft are angularly displaced relatively to each other, so that the battening devices become effective only when the cover sections are in lowered position relatively to the hatch coaming.
  • each battening system may be made very simple and efficient thereby that each battening system comprises a latch which is supported for horizontal longitudinal movement in the hatch coaming and adapted to cooperate with a projection on, or an opening in a skirt depending from the cover section.
  • the transfonnation of the vertical movements of the lifting devices to swinging movements of the arms of the longitudinally extending shaft, and further to horizontal movements of the battening devices, in particular when the latter are in the form of latches, conveniently may be obtained thereby that the arms of the longitudinally extending shaft are adapted to engage and thereby cooperate with recesses in the lifting and battening devices, respectively.
  • FIG. 1 is a perspective view of a part of a section of a hatch coaming with cover, and a system according to the invention.
  • FIG. 2 and 3 are vertical sectional views of a lifting device, in lifted and lowered cover position, respectively.
  • FIGS. 4 and 5 are corresponding sectional views of a battening device, in released and locked position, respectively.
  • FIG. 1 Reference is first made to FIG. 1, the reference numerals used therein being also used in the remaining figures.
  • 1 is a hatch coaming which carries a longitudinally extending rail 2 adapted to cooperate with running wheels 3 mounted on a hatch cover section 4.
  • the rail 2 is interrupted and a rail section 5 is introduced.
  • This section 5 may be vertically moved for the purpose of simultaneous lifting/lowering of all running wheels and thereby the cover section.
  • FIG. I the cover section is shown in lifted position.
  • the vertical movements of the rail section 5 is effected by means of a hydraulic jack 8, FIG. 1, which is stationary mounted at 8 on deck or on a bracket on the hatch coaming.
  • a hydraulic jack 8 is arranged to each rail section 5, Le. to each running wheel 3, and all the jacks are controlled in common, so as to operate in complete synchronism.
  • the plunger of the jack 8 acts upon a rod 9 which may be made in one piece with the rail section 5, or mechanically coupled to the same.
  • the rod 9 is provided with a stop member 9' which, in cooperation with a guide F on the hatch coaming l limits the upward movement of the rail section 5, so as to make the same, when in lifted position, accurately align with the rest of the rail 2 so that the cover sections may be moved without shocks.
  • the rod 9 is provided with a slot 10, particularly shown in FIGS. 2 and 3, and a rotatable shaft 11 is mounted longitudinally of the hatch coaming l and provided with solidly secured arms 12, one arm to each lifting device, with the end of each arm 12 engaging a slot 10. Consequently, when the rod 9 is vertically moved, for the lifting/lowering of the rail section 5, the arm will follow, thereby performing a swinging movement, to the eflect that the shaft 11 is rotated.
  • the side faces of the cover section 4 is provided with a number of brackets or skirts 13, FIGS. 1, 4 and 5, each having a projection 14 extending inwardly towards the hatch coaming l, and at the same time, the hatch coaming is provided with projections 15 positioned immediately above the projections 14 when the cover section is in position for the closing of the hatch.
  • Adjacent to each skirt 13, the shaft 11 is provided with a solidly secured arm 16 which, consequently, will perform a swinging movement when the shaft is rotated by the action of the rod 9 on the arms 12.
  • the free end of each such arm 16 engages a slot 17 provided in a latch 18 which is mounted for horizontal, rectilinear movement through the swinging movement of the corresponding arm 16.
  • Each such latch 18 is guided in guides provided in supports 19 and 20 on the hatch coaming l, and is adapted to be introduced into the space between the projection 14 on the cover section and the projection 15 on the hatch coaming, so that the cover section be locked, battened, relatively to the hatch coaming, FIG. 5.
  • a sealing batten 21 is solidly secured to the cover, and adapted to yieldingly engage the top 6 of the hatch coaming 1, as shown in FIGS. 2 and 3, and 4 and 5, respectively.
  • the arms 12 and 16 are secured to the shaft 11 in such angular positions, relatively to each other that when the rail section 5 is lifted, the latch 18 is moved out of engagement with the projections 14 and 15, and when the rail section 5 is again lowered, the latch 18 is moved outwardly to battening position, provision being made for a sufiicient back-lash in the movement of the rod 9 prior to the lifting of the cover section to ensure that the battening by means of the latch 18 is released before the lifting of the cover section is commenced.
  • a cover system for use on ship hatches and similar openings comprising a number of cover sections, pairs of rollers mounted on horizontal shafts on such cover sections, a hatch coaming supporting longitudinally extending rails comprising rail sections distributed along the length of the hatch coaming at distances corresponding to the distances between the shafts of the cover section rollers, number of vertically extendable devices provided on the hatch coaming each in cooperation with one of the said rail sections, a number of horizontally extendable cover section locking devices, a rotatable shaft extending longitudinally of the hatch coaming and provided with a number of arms each adapted to cooperate with the vertically and horizontally extendable devices, respectively.
  • each of the horizontally extendable devices comprises a latch member mounted for sliding movement in the hatch coaming and adapted to engage an upwardly facing surface on the corresponding cover section.
