Application October 22, 1948, Serial No. 55,905

4 Claims. (01. 223-102) This invention relates in general to self-feeding tacking needles such as are employed by tailors and seamstresses and for the same purposes as that disclosed in my pending application for patent, filed February 28, 1948, Serial No. 12,060.

A primary object of the present invention is to provide a simpler and more facile form of needle than the former type and including a barrel, a spool of thread detachably supported in the barrel and a hollow needle reversibly supported in an end of the barrel whereby the needle may be selectively held in extended position for use or within the barrel when not in use.

An object, also, is to provide a simple but effective threader extensible through the needle for drawing a thread through the needle and which may be held in the needle when the needle is enclosed in the barrel.

Another object is to provide a thread cutter on the needle or adjacent thereto.

Finally, an object is to provide a handy kit in which the needle, spool and threader are commonly housed in the barrel when not in use and are readily extracted from and supported on the barrel for use, or for purpose of repair, replacement or otherwise.

A preferred form of device is shown in the appended drawing in which:

Fig. 1 is a perspective view of the device with the tacking needle supported on the barrel in extended position for use;

Fig. 2 is an exploded view of the parts of the complete kit, except for the threader, in perspective;

Fig. 3 is an enlarged longitudinal sectional view of the assembled kit as when not in position for use;

Fig. 4 is a view of the needle and threader partially inserted therein as when threading the needle; and

Fig. 5 is an enlarged view of the threader.

The complete kit includes an elongated barrel B which is open at both of its ends so as to detachably receive a mounting N at its forward end and a closure E at its rear end. Mounting N carries a needle N which is similar to a hypodermic needle in that it has a longitudinal passage 2 therethrough by means of which thread may be drawn through the passage preparatory to a tacking operation. Mounting N conforms cross sectionally to the inner surface of barrel B so that it may be frictionally held in the forward end of the barrel with the needle extended for use as shown in Fig. 1 or housed in the barrel as shown in Fig. 3.

A cutter C is carried on mounting N and has a radial web 3 which is extensible through an open longitudinal slot 4 at the front end or 4' at the rear end of barrel, selectively, so that the needle may be optionally mounted on either end of the barrel and held against rotation by engagement of web 3 with slots 4 or 4, as the case may be. Cutter C also has a right angularly bent flat flange 5 beneath which at the rear end of web 3 is formed a notched cutting edge 6 so that thread T from the outer end of needle N when drawn rearwardly under flange 5 may be out by means of said cutting edge.

Closure E has a body 1 frictionally held in the end of barrel B, a knurled cap 8 abutting the end of the barrel and a stem 9 extended into the barrel and longitudinally split so as to frictionally support a spool S of thread so that the thread may be unwound and drawn from the spool and through the needle as required for use. Barrel B has a knurled intermediate portion [0 by means of which the barrel may be held in one hand against rotation as the other hand of a user grasps the portion 8 of closure E in order to attach or detach the closure.

The thread T is preferably wound on spool S in the form of a cone with the small end of the cone nearest needle mounting in order that successive convolutions of thread may be more readily unwound than would be otherwise possible and also to more surely prevent tangling or knotting of the thread.

Stem 9 of closure E has a bore l I therein which when all of the parts of the kit are nested in and enclosed by barrel B telescopically receives the inwardly extended needle N while the threader T of the form' shown in Fig. 4 or of Fig. 5 may rest in the passage 2 of the needle.

Threader T may have a handle l2 or not, as desired, and includes a pair of stiff steel wires I3 and [4 or a single wire bent backwardly upon itself to provide separate legs 13 and I4 and either twisted together at spaced points to provide rigid sections I5 and I6 and an intermediate open section I! or, in lieu of the twisted sections the two strands of wire may be covered with solder to form the sections l5 and 16 and of such overall diameter that the threading unit may be readily drawn or urged through passage 2 of needle N. The end of thread T from spool S is inserted between strands l3 and M of section I! and is, gripped by the tension of the wires.

3 The threader with thread attached is then drawn or urged forwardly through passage 2 of the needle and thence backwardly to cutting position on cutter C when by a jerk of the threader the thread will be severed and the threader discarded until again required.

The needle is then mounted in one end of the barrel in extended position for use. If not previously done, a spool S of thread. '12 is positioned on stem of closure E and the closure is inserted in the other end of barrel B. As each tack is made, thread is forced through the material operated upon, the needle is withdrawn and a succeeding tack is made, the projected, thread at each operation being held against withdrawal with the needle and leaving extended loops which serve as markers to guide in cutting; or. sewing the material to conform to a desired pattern.

Of course, the thread is payed out convolution by convolution from spool S as tacking operations proceed and when desired operations are completed, the needle may be detached from barrel B and reversed and again attached to the barrel with the needle extended into stem 9 and if desired with threader T extended through the needle into the barrel, thereby nesting all of the parts within the barrel and requiring only the reversal and reattachment of the needle and removal of the threader in preparation for renewed operations. Rethreading is not usually necessary except when an exhausted spool S must be replaced by a fresh spool or supply of thread. The importance oi the threader and the dependence upon it for the operation of the needle in a tacking operation will be immediately recognized, for without it, the thread could not be forced through the long passage 2 or the needle and without thread supply the needle for its intended purpose would be useless.

It may be noted that the complete tacking kit is of very light weight, compact and inexpensive, and that the length of the barrel is only sufilcient to serve as. a handle which. may be conveniently held by a user.

As shown in Figs. 2 and 3, the threader T may be nested in the closure E when the needle is positioned on the barrel for use and particularly as shown in Fig. 3, when the needle is enclosed in the barrel it may encompass the concentrically supported threader.

It is also contemplated but not essential that the threader may be either permanently or detachably held on the closure E as shown in Fig. 3, but sufiiciently lengthened so that its forward extremity will project substantially beyond the forward end of spool S and into or perhaps from the mounting of the needle so that the mere act of inserting the needle in or withdrawing the same from the barrel may serve to thread the needle.
