H. FRANZ, OF

ART NEEDLE.

Application filed April 18, 1922. Serial No. 554,446.

1 '0 all whom it may concern.

Be it known that we, WILLIAM K. JOHN- SON and LEON 1V. FIsHER, citizens of the United States, residing at East Las Vegas, in the county of San Miguel and State of New Mexico, have invented new and useful Improvements in Art Needles, of which the following is a specification.

The object of our said invention is the provision of an efiicient art needle adapted to be used to advantage by novices as well as those skilled in the art to which it appertains.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification:

Figure 1 is a view partly in section and partly in side elevation of our novel needle, showing the inner member by full lines in retracted position and by dotted lines in forwardly extended position.

Figure 2 is a top plan view of the needle.

Figure 3 is a longitudinal central section of the outer member of the needle.

Figure 1 is an enlarged transverse section taken in the plane indicated by the line l4 of Figure 1, looking forwardly.

Figure 5 is a transverse section taken in the plane indicated by the line 5-5 of Figure 1, looking forwardly.

Figure 6 is an enlarged cross section taken through the finger loop at the rear end of the inner member of the needle.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The outer member of our novel needle is designated by 1 and is preferably formed of sheet metal. The said outer member 1 includes a tubular body with a stop ear 2 at its rear end and with an apertured yarn and thread guide 3 on its forward portion. The forward portion of the said outer member 1 is tapered to a point, and the pointed portion designated by 4 isof channel form in cross-section and is provided adjacent to its forward end with an elongated eye 5 for thread or yarn.

In addition to the outer member 1 the needle comprises an inner member 6 which is preferably, though not necessarily, formed of lighter or thinner sheet metal than the said outer member 1. The said inner memher 6 is sheathed and movable longitudinally in the outer member 1 and is preferably of general tubular form. In its rear portion the said member 6 is provided with a longitudinal slot 7 to receive the stop ear 2 of the member 1. The inner member 6 is also provided with stops 8 to bring up against the rear end of the member 1, and with a finger loop 9, said loop 9 being of con cavo-convex form in cross section in order to lend stiffness and strength thereto. Manifestly the stop ear 2 is adapted to limit the retraction or rearward movement of the in nor member 6 in the outer member 1.

The forward portion of the inner member 6 is reduced and tapered and curved to form a tongue-holding extension 10 that is concavo-convex in cross section.

Appropriatelysecured in the said extension 10 of the inner member 6 is a stee tongue 11 which extends forwardly of the extension 10 and is bent as illustrated to bear and move longitudinally against the member. It will also be understood in this connection that the tongue 11 is adapted to push yarn and hold the same, while the depth of the stitches is determined by the extent to which the inner member 6 is moved with respect to the outer member 1.

The tongue 11 is made of thin steel to enable the said tongue 11 to pass back over the little wad of thread and the material that, incident to the use of the needle, is between the tongue 11 and the eye 5 in the pointed portion 4. As the member 1 is pushed clownwardly, the pointed portion 1 will penetrate about one-sixteenth of an inch in advance without forcing the needle along. Thus the needle makes its own steps, or, in other words, as the operation proceeds, the needle forces itself along.

The thread is passed through the guide 3 and then through the eye 5, the latter from the outer side of the member 1.

It will be manifest from the foregoing that our novel needle is susceptible of being used to advantage by unskilled workers as well as skilled workers; also that the needle is simple and inexpensive in construction and is well adapted to withstand the usage to which devices of corresponding character are ordinarily subjected.

We have entered into a detailed descripinvention in order to impart a full, clear and exact understanding of the said embodiment. We do not desire, however, to be 1mderstood as confining ourselves to the said specific construction and relative arrangement or parts inasmuch as in the future practice of the invention various chan es and modifications may be made such as tall within the scope of our invention as defined in our appended claim.

Having described our invention, what we claim and desire to secure by Letters Patent, 1s

An art needle comprising an outer tubular member with a forward portion tapered to a point and a co nca-vo-convex form in cross-section and provided with an eye, an inner member movable rectilinearly in the outer member and having a forward exten sion concavo-convex in cross-section and destop to brin member; the outer member being equipped in rear of its forward tapered portion with an exterior thread guide and being provided at its rear end with an inwardly extending stop, and the inner member being tubular and heingprovided with a longitudinal slot receiving said stop, it being also provided at its rear end Wltlli a finger loop, and with a g up against the rear end of the outer member.

In testimony whereof we afiix our signatures. r

LEON'W. FISHER.
