SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Tools of the nature of pliers, tweezers, crochet-hooks, etc., capable of other uses, but which may be employed to form knots if desired, are otherwise classified. Pliers are found in Class 81, Tools, subclasses 300+; tweezers in Class 294, Handling: Hand and Hoist-line Implements, subclass 99.2; crochet-hooks in Class 66, Textiles: Knitting, subclass 118.

KNOTTERS

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
	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
	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
	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
	The bill is mounted on a frame, which is moved to-and-fro while the knot is being tied.

7	Sliding jaw
	One member of the bill moving rectilinearly toward or away from the other to grasp or release the cord.

8	Pivoted inner jaw
	The bill member nearer the driving means being pivoted to swing toward the same.

9	Angular drive
	The knotter shank driven directly from a rotating shaft disposed at an angle thereto.

10	Notched-disk cord holder
	Having a flat disk with notches in its periphery for holding the cord ends.

11	Bills
	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
	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
	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
	Comprising a flat disk with peripheral notches to hold the cord ends.

15	Cord guides
	Limited to means for guiding the cord in proper relation to the knot-tying member.

16	Needles
	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.
