TAKEJIRO, YAMAMOTO, OF TOKYO, JAPAN.
INTERTWISTED NET.
Application filed May 29,
To all whom it may concern.-
Be it known that I, TAKEJIRQ YAMAMo'ro, subject of the Emperorof Japan, residing at No. 161 Honmuracho, AZa-bu, Tokyo, Japan, have invented certain new and useful Improvements in Intertwisted Net, of .which the following is a speclfication.
This invention relates to improvements in intertwisted netting.
An object of the inventlon 18 to provide I a strong netting made from cord or rope without employing knots which weaken the net and shorten its life.
Another object of the invention is to improve upon the construction disclosed in my prior Patent No. 1,026,544, dated May 14-,
' the salient features of the invention as ex pressed in the appended claim.
In the drawing,
' Figure l'shows a pair of cords orropes after being intertwisted with the strands shown separated.
Fig. 2 is a view showing the joint after the two intersecting cords have been twisted tightly together.
The material of the netting oftlie present invention is made from cord or rope hav- .and the other cord comprising the strands numbered 4, 5 and 6. Before the cords are twisted, they are interlocked in the manner 7 shown in Fig. 1, where each strand of each cord is shown as passing between two of. the three pairs of strands of the other cord.
Specification of Letters Patent. Patented $611913. 13, 1921- 1919. Serial No. 300,569.
Thus strand 4 is passed between strands 1 and 2 and also between strands 1 and 3, but is not passed between strands 1 and 2 Strand 3 of the-other cord is passed between strands 5 and 6, and between strands 4 and 5, but not between strands 4: and 6. Simia lar statements may be made of all the six strands of the intersecting cords.
When once the strands have been connectedinthe mannerillustrated in Fig. 1, the intersecting cords will be twisted, the twisting taking place simultaneously so that the joint is ultimately intertwi'sted tightly to form the compact knotless joint" illus trated in Fig. 2. The joint of the invention,
unlike a knotted joint, has no greater thick T ness than the thickness of the individual cords intersecting to form the joint. The three intertwisted strands of the intersecting cords positively prevent any shifting of the two cords relatively to each other.
In the construction of the prior patent referred to, the joint is not solid enough and will loosen after a short time. Especially is it not suitable for a large cord. The present invention has been devised to eliminate the disadvantages of the prior construction. Here the joint is very solid and is suitable for large cords or ropes. The meshes of the netting are of uniform strength and may not be deformed. Even when the netting is nearly worn out the meshes will maintain their proper size, thus making the netting a very durable one.
What is claimed is:
An interlocked netting joint formed from two intersecting cords or ropes, each cord comprising three strands, each strand ot either cord being passed between two of the three pairs of strands of the other cord, no two strands of either cord passing between the same strands in the same direction, the two cords being subsequently twisted tightly to form a knotless joint.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
