Patented Aug. 23, 1949 FLY-TYING BOBBIN Ivan W. Arnold, North Hollywood, Calif. Application April 14, 1947, Serial No. 741,363
The present invention relates to fly-tying bobbins. I
In the making of flies for fishing purposes, the flies are usually formed on the fish hook. To accomplish this, feathers of different colors are tied to the hook by means of thread. Usually the thread is wrapped around portions of the feathers and the hook, the final fly being of a form which is attractive to a fish, causing it to snap at the fly and thus engage the hook. The making of flies has become an art, requiring a means for rapidly forming the fly on the hook.
An object of the present invention is to provide a means whereby thread may be rapidly wrapped around the various feathers and the hook to form a fly, the operator at all times being able to observe his handicraft.
A further object of the invention is the provision of a device for tying flies which is easily manipulated, and which assures a better fly construction.
It has been found that use of the present invention increases an operators speed in the forming of flies on a fish hook. It is not uncommon for an operator with fair skill using the present device to form thirty flies an hour.
A further object of the invention is a fly-tying bobbin which is simple of construction, easily loaded with thread, attractive in appearance, inexpensive in cost of manufacture, and superior to devices now known to the inventor.
In the drawing:
Figure 1 is a side view of the invention looking in the direction of the arrow I of Figure 2,
Figure 2 is an end view looking in the direction of the arrow 2 of Figure l, and,
Figure 3 is a sectional view on an enlarged scale, taken on the line 3-3 of Figure 1.
Referring now to the drawing:
The fly-tying bobbin of the invention is designated as an entirety by the numeral I, and includes a body 2, one portion 3 of which is of uniform external diameter, while an elongated concavedly tapered portion 4 extends from said portion 3 to form an extension or nose portion. The portion 3 is provided with an enlarged bore 5 opening outwardly from one end of the body, as shown at 6; while the wall adjoining said bore 5 and inwardly of the body is concavedly reduced in diameter, as shown at I, to where it merges and communicates with an axial bore 8 in the extension or nose 4, and which bore 8 in turn communicates with a reduced diameter axial bore 9 extending to the tip ID of the nose. The portion 3 is formed with axially aligned transverse bores II and I2, bore I2 being of greater diameter than bore II; portion 3 is bored inwardly at I3, and communicates with bore II. The bore I3 is reduced in diameter at I4. Such reduction may be accomplished in any convenient manner, such as by peening the end of the body adjacent said bore where it communicates with the bore II. Bore I3 is adapted to receive a ball I5, which projects within bore I I, said ball being urged to said position by a coiled spring I6 held within the bore I3 by a nut I! in engagement with threads formed in the wall bounding the bore I3. A bobbin I8 extends between and is received in part within the bores II and I2. The bobbin is of the usual spool type, having heads I9 and 20. The head I9 has a diameter slightly less than the internal diameter of bore II, and said head is formed with an annular groove 2 I. The head 20 has two portions of different diameter, as shown at 22 and 23, the portion 22 fitting snugly within the bore I I, while the portion 23 engages the outer surface of the portion 3 and limits movement of the bobbin in one direction. The portion 3 is formed with a transverse slot 24 extending from the end of said body to the bore I2.
The operation, uses and advantages of the invention just described are as follows:
The bobbin is wrapped with thread 25, whereupon the thread, with the bobbin exterior of the body, is passed through the bores 8 and 9. This may be accomplished by running a needle having a hook end through the said bores to contact the thread and draw the same through the said bores. After this is accomplished, the bobbin may be placed in the body by passing the head I9 first through bore I2 and then into bore II, at which time the spring-pressed ball I'5 will be received within the annular groove 2|. The thread may then be passed through slot 24 so that upon pulling that portion thereof which extends through the tip I0, the thread will assume the position shown in Figure 3. The ball I5 exerts enough pressure against the head to permit easy rolling of the bobbin, and just sufiicient friction to maintain a proper tension on the thread 25 when the thread is being used to form a fly. In other words, the spring-pressed ball acts as a friction means for the bobbin.
The operator, in the use of the invention, uses a suitable clamping means for holding the fish hook. He then takes the various objects which make up a fly, such as small feathers, and while holding them in one hand against the fish hook, rapidly wraps the thread about the hook and the feathers, adding such other objects as may be necessary to form a complete fly. The long pointed nose of the device allows the operator to rapidly wrap the thread about the fly and the hook, and further permits a tying thereof when desired. Proper tension is maintained on the thread by maintaining a friction means for the bobbin. The use of this device assures that the fingers O-fathfl operator-are not brought into con-1 tact with the impalingaportioniofiftheahook; the result that the operator does not suffer any injury to his fingers while forming the fly. The 1 long tapered nose permits the operator to watch the forming of the fly at all times, his vision not being obscured as would be the caseif-he utilized;
the fingers of both hands for Wrapping and tying the thread about the hook and the fly.
