DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a needle device for the finishing of lines or cordage, especially for the splicing of rounded-plaited lines or braided cordage, comprising an end portion tapered at the front and a pipe portion directed rearwardly from the end portion, the opposite end of which is open for the endways reception of the end of the line or the strand end of the cordage.
The present invention is especially appropriate for use in splicing so-called round-plaited line, that is to say a line which on axial compression or clenching together forms an axially extending central hollow space together with relatively large lateral openings between the braided filaments to said central hollow space. In this way there can be formed a spliced noose on the end of the line by for example threading the line initially S-shaped right through a line portion and by conclusion threading the outer end of the line axially inwards into said central hollow space, the outer end of the line is finished internally screened in said line portion. Correspondingly spliced loops or other splice connections can also be fashioned for example in conventional braided cordage.
From U.S. Pat. No. 4,158,281 a needle is known for the afore-mentioned purpose. A needle is shown which, outside the rear pipe end, is provided with two opposite hook portions which are adapted to be tightened against an intermediate line end from each of its mutually opposite sides. After the hook portions are fixed to the line end, the hook portions and the line end are introduced a distance within the pipe end by turning the needle about its own axis relative to the hook portions and the line end fastened thereto. On dismantling the line end from the needle the hook portions and the associated line end must correspondingly first be turned relative to the needle and thereafter the hook portions opened relative to each other for withdrawal of the line end.
The known needle has a relatively complicated construction and is relatively complicated to use, the fastening in position of the line end in the needle and the releasing of the line end from the needle being relatively time-consuming work. In addition several problems can arise in the fastening and releasing of the line end under normal, relatively cool or cold working conditions at sea or under difficult working conditions, the fastening or releasing demanding great dexterity.
The present invention provides a needle with a far simpler construction and with a far simpler mode of operation, so that the splicing operations can be carried out in an easier and more rapid fashion than hitherto possible. An objective is to be able to produce the needle so cheaply that it can for example be included as standard equipment for a roll of rigging or other suitable rope portion length which is purchased by a user.
The device according to the invention is characterized in that the pipe portion has at its rear end an elongate laterally directed opening for the reception of the end of the line or the strand end of the cordage in the pipe portion of the needle, and in that from the bottom side of the pipe portion, adjacent the laterally directed opening, there project one or more hook portions obliquely upwards towards the laterally directed opening and obliquely forwards relative to the rear end of the pipe portion, the distance from the inner boundary edge of the opening to the outer end of the hook portion being somewhat larger than the diameter of the line or strand.
By means of the simple design of the needle according to the invention, moving parts are avoided, and there is the possibility for mounting the line end or the strand end in the open end of the needle and correspondingly dismantling the line end from the needle, when this is necessary, by means of a simple hand grip. Using a device according to the invention one is not dependent upon having to use the fingers to readjust movable locking means or other movable portions of the needle, but can, while the needle is received in one hand, stick the line end o
