M W W CARL W. SELLS'IEDT, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-MALE TO JOHN 1. LINDQUIST, OF MINNEAPOLIS, MINNESOTA.

TUFTING-NEEDLE.

To all whom it may concern:

Be it known that I, CARL IV. SELLsrEnr, a subject of the King of Sweden, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Tufting- Needles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved tufting device for producing nap on the surface of thin fabric; and to this end it consists of the novel devices and combinations of devices hereinafter de scribed and defined in the claim.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation, showing the improved device in operation, the needle thereof being withdrawn from the fabric. Fig. 2 is a view corresponding to Fig. 1, but showing the device with its needle inserted through the fabric and with some parts broken away. Fig. 3 is a rear elevation of the device, some parts being broken away. Fig. I is a horizontal section on the line 122* x of Fig. l; and Fig. 5 is a horizontal section taken on the line m 00 of Fig. 3.

To a suitable handle 1 is secured a depending tubular needle 2 and a pin 3. The needle 2 is longer than the pin 3, and the tubular passage therethrough is open near its upper and lower extremities or on its rear side, or that side which is adjacent to the pin 3. At its upper end, the handle 1 is provided with an upwardly projecting stem at. l

The character y indicates the fabric and the character 11/ the yarn or material used for tufting and which is threaded through the tubular needle, as shown in Figs. 1 and 2. Preferably the tubular needle 2 is triangular in cross section, as shown in Fig. 4, while the pin 3, which is of very much smaller diameter, is round.

To limit the movements of the needle and pin through the fabric, a stop device, preferably in the form of aspring bar 5 having laterally bent ends 6 and 7, is provided. The bent upper end 7 works on the stem 4,

while the bent lower end 6 works on the needle 2 and pin 3. The intermediate portion of the spring bar 5 is thus held in close engagement with the handle 1, and at its intermediate portion it is provided with several perforations 8, through which a pin 9 on the said handle is adapted to project to adjustably secure the stop in different positions, so as to variably limit the movement of the needle through the fabric.

WVhen the device is moved downward from the position shown in Fig. 1, the needle 2 first passes through the fabric y, and immediately following the same, the pin 3 passes through the yarn 3 which has just been withdrawn from the needle and which is pressed against the fabric and also passed through the fabric, thereby holding the yarn so that the downwardmovement of the needle can not withdraw the tufts or stitches previously made through the fabric. There will, of course, be considerable friction be tween the yarn and the needle, so that the action of the pin 3 in positively holding the applied portion of the yarn to the fabric and thereby causing the yarn to be positively drawn through the needle under its downward movement, is very important. IVhen the needle is drawn upward, that portion of the yarn which is on the outside of the needle will be looped upon itself and partly drawn back through the fabric, as the needle is moved forward to make its next: stitch or tuft; but the amount of yarn that will be drawn through the needle and, hence, the

length of the tuft, will depend on the position of the stop 6, it being assumed, of course, that the needle is forced downward as far as permitted by the said stop. The tufts will be considerably less in depth than the amountof yarn drawn through the needle at each downward movement.

The device above described is capable of large range of use. It may be used in making mats, rugs, etc., and it may also be used in stitching ornamental designs on fabrics. Furthermore, the device, while highly efiicient for the purposes had in view, is of very small cost.

What I claim is:

In a device of the kind described, the combination with a hand-piece having a depending needle and pin independently and rigidly secured thereto and also having an upwardly projecting stem, of a spring stopbar bent laterally at both ends and provided forations in the intermediate portion of said With a single perforation in each laterally spring stop-bar, substantially as described. 10 bent end, the said needle and pin projecting In testimony whereof I aifix my signature through one of said perforations and the in presence of two Witnesses.
