However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

(10) Referring to FIG. 1, a multi-needle embroidery machine 100 is shown having a needle bar 102 with a plurality of retaining members 104 each supporting an embroidery needle 106 that extends vertically downwardly from the retaining member 104 such that the tip portion 108 of the embroidery needle 106 extends towards a corresponding aperture 110 in a pressure foot 112 of the embroidery machine 100. Preferably, each retaining member 104 includes a screw 114, or other similar device, that operates to tighten the retaining member 104 and secure the embroidery needle 106 in position with the retaining member 104 for operation of the embroidery machine and operates to loosen the retaining member 104 to remove the embroidery needle 106 from the embroidery machine 100.

(11) As illustrated in FIG. 2, a non-limiting illustration of an embroidery needle 106 is shown and includes an elongated shaft 116 having an upper shank portion 118 for attaching to the retaining member 104 when in a locked position for operation of the embroidery machine 100, and a lower section 120 having a tip portion 108 and an eye 122 and a longitudinally extending groove 124 that when the embroidery needle 106 is properly positioned on the embroidery machine 100 it faces directly outwardly therefrom.

(12) Referring to FIGS. 3 and 4, a preferred embodiment of the needle inserter 126 of the subject invention is shown comprising an elongated handle 128 having a first end portion 130 and a second end portion 132, a releasable support 134 at the first end portion 130 and an elongated element 136 extending perpendicularly from the first end portion 130 having a perpendicular outwardly extending distal end 138. The needle inserter 126 operates such that an upper portion 140 of the lower section 120 of the elongated shaft 116 of an embroidery needle 106 engages the first end portion 130 on the needle inserter 126 by the releasable support 134 such that the distal end 138 of the elongated element 136 extends through the eye 122 of the embroidery needle 106. As shown, the elongated handle 128 is sized such that a user can comfortably hold the second end portion 132 of the elongated handle 128 in one hand during operation and is formed from wood, plastic, metal or other rigid material.

(13) In a preferred embodiment of the invention the releasable support 134 is in the form of a clamp having two generally elastic arms 142 that operate to support the embroidery needle 106 on the needle inserter 126 and flex outwardly to release the embroidery needle 106 from its position on the needle inserter 126, such as when the embroidery needle 106 has been secured in proper position in the retaining member 104. In another preferred embodiment of the invention, as illustrated in FIG. 5, the releasable support 134 is in the form of a magnet that operates to magnetically hold an embroidery needle 106 in place and cooperates with the distal end 138 of the elongated element 136 to maintain the embroidery needle on the needle inserter and to release the embroidery needle 106 from position on the needle inserter 126. In another preferred embodiment, the distal end 138 of the elongated element 136 is in the form of a magnet that operates to magnetically hold the embroidery needle 106 in place on the needle inserter 126 and cooperates with the releasable support 134 to maintain the embroidery needle on the needle inserter during insertion of the embroidery needle 106 into the retaining member 104.

(14) Referring to the Figures, the methodology or using the needle inserter 126 of the subject invention is shown whereby a used embroidery needle 106 that is positioned within a retaining member 104 is removed from the retaining member 104, such as by loosening a screw 114, and sliding the used embroidery needle 106 downwardly until the shank portion 118 of the elongated shaft 116 of the used embroidery needle 106 disengages from the retaining member 104 (step 200). The used embroidery needle 106 is then moved away from the pressure foot 112 (step 202) and the embroidery needle discarded (step 204). The needle inserter 126 operates such that a user holding the second end portion 132 of the elongated handle 128 inserts elongated shaft 116 of a new embroidery needle 144 (replacement needle) into position such that the releasable support 134 of the needle inserter 126 engages the upper portion 140 of the lower section 120 of the elongated shaft 116 of the new embroidery needle 144 and that the distal end 138 of the elongated element 136 extends through the eye 122 of the embroidery needle 106 thereby securing the new embroidery needle 144 in position on the needle inserter 126 (step 206). Holding the second end portion 132 of the elongated handle 128, the user moves the needle inserter 126 with the new embroidery needle 144 upwardly such that the shank portion 118 of the elongated shaft 116 of the new embroidery needle 144 engages with the retaining member 104 and that the tip portion 108 or the elongated shaft 116 points vertically downward towards the aperture 110 of the pressure foot 112 (step 208). The retaining member 104 is then tightened, such as by tightening the screw 114, so that the shank portion 118 of the elongated shaft 116 is secured within the retaining member 104 such that the new embroidery needle 144 is in its proper orientation O (such that longitudinally extending groove 124 is facing properly, directly away from the embroidery machine 100) and vertical alignment (V) (step 210) so that the shaft is vertically aligned with the center of the aperture 110 of the pressure foot 112 so that during operation of the embroidery machine the needle will move in reciprocating vertical movement within specifications of the particular embroidery machine. After the new embroidery needle 144 has been secured in place, the user then moves the needle inserter 126 such that the distal end 138 of the elongated element 136 no longer extends through the eye 122 of the new embroidery needle 144 and the upper portion 140 of the elongated shaft 116 separates from the releasable support 134 (step 212). After the new embroidery needle 144 has been attached to the embroidery machine 100, the user directs thread 146 along the longitudinally extending groove 124 of the new embroidery needle 144 and inserts the free end 148 of the thread 146 through the forward face 150 of the eye 122 of the new embroidery needle 144 (step 214).

(15) It should now be apparent that the embroidery inserter of the subject invention operates such that in the event an embroidery needle breaks a user can remove the used needle from its position within a retaining member by sliding the used needle downwardly until the it disengages from the retaining member. The used embroidery needed is then discarded. Using the needle inserter of the subject invention having a releasable support and an elongated element with a distal end, the shaft of a new embroidery needle is placed into position on the needle inserter such that the releasable support and the distal end of the elongated element of the needle inserter engages the elongated shaft of the embroidery needle to secure the new embroidery needle in position on the needle inserter. The needle inserter is then moved such that the shank portion of the elongated shaft of the new embroidery needle engages with the retaining member. The retaining member is tightened so that the shank portion of the elongated shaft is secured within the retaining member such that the new embroidery needle is in its proper orientation and alignment. The needle inserter is then moved so that the shaft of the new embroidery needle is no longer engaged with the releasable support and the distal end of the elongated element.

(16) It should now be apparent to one skilled in the art that the needle inserter can be used to place an embroidery needle in proper orientation and alignment on an embroidery machine. It should also now be apparent that the needle inserter of the subject invention is relatively inexpensive to manufacture and is relatively simple in design. Further, the needle inserter operates such that a user can easily align the embroidery needle such that is in a true vertical position with respect to the embroidery machine and to maintain the embroidery needle and thread in position while tightening the retaining member thereby minimize the likelihood that the needle is not properly orientated and aligned thereby minimizing the likelihood that the embroidery needle will bend or break or cause loop failure and thread breaks during operation of the embroidery machine.
