CLASS 289, KNOTS AND KNOT TYING

1.2	KNOTS:

	This subclass is indented under the class definition. An interlacement of portions of one or more elongated flexible elements (e.g., strand, rope) forming a tie or fastening and including any bend or hitch.

1.5	METHODS:

	This subclass is indented under the class definition. Methods.

2	KNOTTERS:

This subclass is indented under the class definition. Devices for forming a loop through which a portion of the cord is passed and the loop tightened thereon.

SEE OR SEARCH THIS CLASS, SUBCLASS:

17,	for a device adapted to assist the hand or operated by hand to form a knot.

3	. Weaver’s knot:

	This subclass is indented under subclass 2. Whereby a knot is tied comprising two loops, the terminals of one extending through the bight of the other on the same side and one terminal of the second loop extending through the bight of the first loop, the other terminal of the second loop extending between the first terminal of the second loop and the terminals of the first loop.

4	. Square knot:

	This subclass is indented under subclass 2. Whereby a knot is tied comprising two loops, with the terminals of each extending through the same side of the bight portion of the other.

5	. Rotary lateral bill:

	This subclass is indented under subclass 2. Having a bill comprising two members adapted to receive and hold a cord between them, said members extending laterally from a rotating shank.

6	.. Swinging knotter frame:

	This subclass is indented under subclass 5. The bill is mounted on a frame, which is moved to and fro while the knot is being tied.

7	.. Sliding jaw:

	This subclass is indented under subclass 5. One member of the bill moving rectilinearly toward or away from the other to grasp or release the cord.

8	.. Pivoted inner jaw:

	This subclass is indented under subclass 5. The bill member nearer the driving means being pivoted to swing toward the same.

9	... Angular drive:

	This subclass is indented under subclass 8. The knotter shank driven directly from a rotating shaft disposed at an angle thereto.

10	.... Notched-disk cord holder:

	This subclass is indented under subclass 9. Having a flat disk with notches in its periphery for holding the cord ends.

11	.. Bills:

	This subclass is indented under subclass 5. Limited to the structure of a pair of cooperating members projecting from a shank for forming the loop and pulling a portion of cord therethrough. Does not include gearing for operating the members. May include cam or spring for opening or closing the jaw.

12	. Sleeve and spindle:

	This subclass is indented under subclass 2. Having a sleeve, within which is a spindle, the spindle and sleeve being relatively movable to form a loop, and a twine-engaging member on the end of the spindle to pull a portion of the cord through the loop. Sometimes called "cylinder-knotter."

13	. Cord holders:

	This subclass is indented under subclass 2. Improvement limited to means for holding the ends of the cord while the knot is being tied. Includes cord-cutter when the same is carried on the cord-holder, the rest of the knotter being old.

14	.. Notched disk:

	This subclass is indented under subclass 13. Comprising a flat disk with peripheral notches to hold the cord ends.

15	. Cord guides:

	This subclass is indented under subclass 2. Limited to means for guiding the cord in proper relation to the knot-tying member.

16	. Needles:

	This subclass is indented under subclass 2. Limited to means for presenting the cord to the cord-holder and attachments therefor. Includes knife, guard, or compressor-arm if the same is carried by the needle.

16.5	MACRAME:

	This subclass is indented under the class definition. Method or apparatus for effecting or facilitating the knotting of cords or similar strand materials into a coarse lace or a decorative fringe.

17	HAND IMPLEMENTS:

This subclass is indented under the class definition. Means peculiarly adapted to assist the hand or operated by hand to form a knot.

SEE OR SEARCH CLASS:

57,	Textiles: Spinning, Twisting, and Twining, subclass 23 for implement such as marlin spikes employed in splicing operations.

18.1	MISCELLANEOUS:

	Tying devices which do not fall within the definition of any of the more specific subclasses in this class (289).
