Definitions

  • the invention is concerned with an apparatus for the slowing-down of the swing of a boom, for instance on board of a vessel, such as a boom, tiller and the like.
  • the invention aims at presenting an apparatus that is relatively small and light and consequently easy to handle. Furthermore the apparatus is easy to manufacture.
  • the apparatus made according to the invention distinguishes itself by a closed casing with two oval openings, between which a channel - included in the casing - extends in order to take in a flexible element such as a rope, which is attached to the ship between two points that are at some distance from each other.
  • the apparatus has been applied in such a way that at a swing of a boom or tiller the flexible element is being pulled through the channel, the latter exhibiting a slowing-down effect on the flexible element as a result of the friction.
  • the channel-form may be arbitrary but preferably it is bend over.more than 360 . Because of this the flexible element will easily clench itself in the channel, thus increasing the slowing-down activity.
  • the casing consists of at least one hole for the taking in of a fastening-element, with the perpendicular of the hole placed vertical on the perpendicular of the two aforementioned oval openings. This measurement achieves that the casing is not pulled in an angle with regard to the fastening-pin when the flexible element is tightened, thus preventing wear.
  • the casing has a principally circular shaped form, the form accommodating the continuous channel. Consequently the casing becomes singularly light.
  • the application of the continuous channel nevertheless provides the security that the flexible element is being carefully guided and cannot become all mixed-up.
  • the invention is further concerned with a procedure for the fabrication of the casing for the abovementioned apparatus, the procedure of which distinguishes itself because a tube - made of flexible material - is bend in the desirable form, over, for instance, at least 360 , next it is applied into a casting-mould, after which the mould is filled with a plastic-mass. It will be obvious that with this procedure a slowing-down apparatus can be accomplished in a particularly cheap way
  • the picture shows:
  • the cipher 1 denotes the vessel, on which deck casing 2 of the slowing-down apparatus, as hereafter specified, has been attached.
  • a flexible element has been guided in the shape of a rope 3, which on either side leads to a pully-block 5 of boom 6 via two points on deck - in the form of pulley 4 - which are some distance apart.
  • An end of the rope 3 is attached to the pulley-block, whereas the other end leads to the fastening devices 7 for the tightening of rope 3 via a leeward-wheel attached to the pulley-block.
  • FIG. 3 illustrates the winding form of tube 9, where it must be mentioned that the oval ends 10 of the tube coincide with the oval openings 8 of casing 2 and that the perpendicular of the winding form of tube 9 is placed vertical on the perpendicular of the two aforementioned oval openings of the tube.
  • the fabrication of the casing can take place in a simple way by bending tube 9 in advance in the desired form, subsequently bringin it into a mould, not shown here, after which the mould can be filled with the plastic mass, for instance synthetic material.
  • hole 11 can already be spared for the attachment of a fastening-pin 12, for instance the screw-pin of fastening 13. It must be noticed that the perpendicular A-A of hole 11 is placed vertical on the perpendicular of casing 2, in which the oval openings 8 are to be found.
  • Rope 3 can be guided into the channel in a simple manner by pushing it into an opening 8 on one side. Due to the symmetrical formation of openings 8 no reaction-moment will appear on pin 12 at a certain tension of rope 3.
  • the apparatus works as follows:
  • the fastening-measurements 7 function to tighten rope somewhat in advance at a certain position of boom 6.
  • Fig. 4 shows the possibility of attaching casing 2 of the slowing-down apparatus directly to boom 6 by means of fastening 13.
  • one end of rope 3 is permanently attached to a place on the deck of the vessel, whereas the other end is guided via block 14 to the helmsman's place, in which case rope 3 can arbitrarily be tightened in advance and fastened.
  • the rope will not undergo a shift with regard to the vessel, but casing 2 with boom 6 will be dragged along the rope.
  • the slowing-down effect remains the same.
  • Fig. 5 and 6 each show a different way to attach the apparatus, which speak for themselves and are not limited.
  • casing 2 of the slowing-down apparatus is joined to the shealing at the front of the mast via fastening 13
  • in fig. 6 casing 2 of the slowing-down apparatus is attached to the foot of the mast.
  • rope 3 is attached to a point on deck of the vessel with one end, then it runs via a conducting-element attached to the boom through the slowing-down apparatus back to the conducting-element on the boom ans via a fasteningpoint on deck to a tightening-element at any arbitrary place near the helmsman.
  • tube 9 can arbitrarily have more or less windings depending on the slowing-down effect. Due to the use of a closed channel rope 3 will never get mixed-up in the windings, as a result of which the slowing-down effect remains best and no blockage can arise.
  • oval openings 8 in casing and of course in tube 9, make it possible to attach the rope 3 on the vessel in different angles, to prevent wear of the rope.
  • the apparatus may just as well be applicable on other places than ships.
