Patented May 3, 1949 UNITED STATES PATENT OFFICE FISHERMANS BARREL KNOT TIER James W. Harvey, Lakeville, Conn. Application February 21, 1947, Serial No. 730,153
12 Claims. 1
My invention relates to means for tying what are commonly called barrel knots such as are used to tie together strands of natural or artificial gut for forming fish line leaders, and this application is a partial continuation of my application #713,478, filed December 2, 1946.
The present application is intended to cover a simple form of apparatus, which can be carried and used by amateur fishermen, and others, either at home or in the field.
In the form shown, a base plate is provided with means for mounting two supports for grippin the strands to be united and a central holder for twisting the strands and having grippers for holding the tips of the strands and drawing them through the twisted strands when tying the knot.
Fig. 1 is a perspective view of one form of device involving my invention showing the ends of two strands to be connected.
Fig. 2 is a transverse sectional view showing the mounting of one of the strand supports.
Fig. 3 is a transverse sectional view showing the mounting of the central strand holder.
Figs. 4, 5 and 6 are front views showing successive stages of the tying action.
Fig. 7 is an enlarged view showing a barrel knot as tied on this device before the ends are clipped off.
Fig. 8 is a detail perspective view of a modified form of strand gripping support.
In the simplest form the device has a base plate I with two strand gripping supports II and I2, spaced apart from each other and a central strand holding member I3 between them. Each support has a central post I I, and two spring jaws I5, I secured to the opposite sides of the post I4 by a rivet I5. Each support is preferably demountably secured to the base by mounting it in a resilient bushing II in the base. A recess I8 in the lower face of the base accommodates the feet I9, I9 of the side jaw members I5, I5.
The central holding member I3 consists of a central post 20 and spring jaws 2|, 2| secured to its opposite sides by a rivet 22. The base is provided with a resilient socket or bushing 23 for the holding member I3. This socket is fixed in a recess 24 in the base and serves to frictionally hold the member I3 when the knot is being completed. When tying a knot the base plate is held stationary.
To join two strands by a barrel knot the two strands are first inserted into the supports I and I2. For instance, the main part of strand 25 is 2 slipped between post I4 and one of the jaws 15 of support I I and similarly is secured to post I2 leaving its tip 26 extending beyond it to the right. Strand 2'! is then mounted in posts I2 and II in the similar manner leaving its tip 28 extending to the left of support II.
The central holder I3 is then inserted between the strands and turned so as to twist the strands 3 or 4 times. This central holder I3 thus constitutes a twisting member or means for twisting the strands which are held by the supports I I and I2. Preferably the supports II and I2 are mountedin resilient bushings II so that the supports can yield toward each other as the strands are twisted thus avoiding slippage of the strands as they are twisted and consequent possible chafing of the strands. After twisting the strands the lower end of the holder I3 is inserted in the socket 23.
The tips 26 and 28 are then withdrawn from the supports I2 and II, respectively. and tucked between the central post 20 and the spring jaws 2|, 2| as shown in Fig. 4.
The supports and holding members are preferably formed of strips of resilient non-corrodible metal and the tips of the jaws I5 and 2| are preferably rounded off and spread or bent outwardly to facilitate the insertion of the strands alongside of the posts I4 and 20, respectively.
After the tips of the strands have ben secured to the central member I3 the main parts of the strands are released from the supports II and I2 and pulled outwardly as shown in Fig. 5, so as to retract the twisted strands from the center member I3 and the tips 26 and 28. Thetips 26 and 28 are then released from the jaws of the holder and strands 25 and 21 are drawn apart as shown in Fig. 6.
The strands are then pulled away from each other so as to form the knot by drawing, the turns of the strands tightly together as shown in Fig. '7.
The tips are then cut off close to the knot unless a tippet is desired, in which case only one of the tips would ordinarily be out 01f.
When not in use the supports II and I2 and the holder I3 can be conveniently stored in the pockets 29, 29 and 30, respectively, which extend transversely of the base plate. (See Fig. 1.)
An alternative form of the support I I is shown in Fig. 8. In this case the support II consists of a rubber member slitted at 3|, 3| to form a central member I4 with the two resilient gripping jaws I5, I5 for holding the strands to be joined in the same manner as above described.
