DESCRIPTION:
BRIEF SUMMARY
The present invention relates to apparatus for looping tying material about the eye or eye shank of a button.
Padded articles such as mattresses or cushions are often indented by means of two buttons, each having an eye or eye shank, being linked on either side of the padded article. The buttons are connected by tying material, such as thread, twine, or the like which passes through the eye of a first button, through the padded article and through the eye of a second button. The tying material is looped around the eye of the second button thereby securing the button, the needle is withdrawn and then the tying material knotted about the first button. The depth of the indentation is determined by the length of the tying material linking the two buttons.
Apparatus for securing buttons in padded articles in such a manner is described in United Kingdoms Pat. No. 1536052 published Dec. 20, 1978 and assigned to Styrtenik Olof Nestenius, A. B., of Helsingborg, Sweden. The apparatus therein described uses a rotary hook, similar to that used on a sewing machine, for looping tying material around the eye of a second button. Such a hook suffers, however, from the disadvantage that the tying material is not automatically released from the hook after looping has occurred with the result that the operation of the apparatus is delayed while the tying material is disconnected from the hook.
The present invention has as its object to provide improved apparatus for looping tying material around the eye of a button which overcomes the aforesaid disadvantage.
The present invention provides apparatus for looping tying material about the eye of a button comprising:
means for supporting a button having an eye or eye shank extending outwardly from a reverse side thereof,
means for passing a doubled length of tying material through the eye of a button supported by the supporting means, and
means for looping one of the two strands of a said doubled length of tying material about the eye or eye shank of a said button,
the looping means comprising a shoulder for engaging a said one strand of a doubled length of tying material beyond where the tying material passes through the eye of the button, the looping means being rotatable about an axis which is inclined relative to the axis of a button supported by said supporting means when the apparatus is in use whereby said one strand will be carried by said shoulder around the eye or eye shank of the button first in a direction away from the button so that a loop is formed in said strand around the looping means to maintain the strand in engagement with said shoulder, then in a direction towards the button to disengage the loop from the looping means and finally again in a direction away from the button to disengage the strand from said shoulder.
Said shoulder may be provided on a semi-conical member which partially surrounds a button supported by the button supporting means when the apparatus is in use. Said semi-conical arcuate member may comprise a base portion mounted on one end of a shaft which is rotatable to rotate the looping means and an arcuate wall which extends both axially and radially outwards from said base portion, the arcuate wall having a leading edge, a trailing edge and an arcuate outer edge remote from the base portion and extending between the leading and trailing edges. A cut-out is provided at the junction of the leading edge with the arcuate outer edge to form said shoulder. Both the leading edge and the trailing edge are inclined relative to a plane in which the axis of rotation of the looping means lies, the leading edge being inclined from the base portion away from the direction of rotation of the looping means and the trailing edge being inclined from the base portion toward the direction of rotation of the looping means. With such an arrangement a said strand of tying material will be directed toward and into engagement with the shoulder by the leading edge should the strand initially engage the leading edge instead of the shoulder. As the looping means is rot
