Abstract
Abstract A tufting button which preferably is molded as an integral unit of plastic, and has a head portion and a shank portion. The shank portion has a first longitudinal slot formed in it which extends from its free end towards its attachment to the head portion, and a second longitudinal slot which is angularly offset with respect to the first longitudinal slot and which is closed at the free end of the shank portion. These two longitudinal slots are connected by two generally horizontal slots which extend from the respective edges of the first longitudinal slot to the second longitudinal slot, such that the button can be attached to a tufting cord by extending the latter through the first longitudinal slot and then rotating the tufting button to extend the tufting cord through the two horizontal slots into the second longitudinal slot. The tufting cord then is lockingly engaged in the second longitudinal slot, by pulling it toward the free end of the shank portion to seat it within the second longitudinal slot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A tufting button having a head portion and a shank portion, there being a first slot extending longitudinally through said shank portion from the free end thereof, there being a second slot extending longitudinally through said shank portion, said second slot being angularly displaced with respect to said first slot and being closed at the free end of said shank portion, there being a pair of generally horizontal slots extending in opposite directions through said shank portion from the respective edges of said first slot to said second slot, whereby the button can be secured to a tufting cord by extending the tufting cord through the first slot and by rotating the button to extend the tufting cord through the pair of horizontal Slots into the second slot.
Claim 2
Dependent Claim
128 words
A tufting button having a head portion and a shank portion, there being a first slot extending longitudinally through said shank portion from the free end thereof, there being a second slot extending longitudinally through said shank portion, said second slot being angularly displaced with respect to said first slot and being closed at the free end of said shank portion, there being a pair of generally horizontal slots extending in opposite directions through said shank portion from the respective edges of said first slot to said second slot, whereby the button can be secured to a tufting cord by extending the tufting cord through the first slot and by rotating the button to extend the tufting cord through the pair of horizontal Slots into the second slot.
