cames, l pins w' f which* etd through heres 20, Fig. l, is engaged with the looper points i by engaging successive loops 21 of the sweater fabric, along the desired line of reenter-cement, with successive points of the looper (see Figs. 2 and The end of the reen'lorcing tape 30, which has been drawn through the tension device t, u, is then engaged by hand with one or more of the looper points that engage the loops at one end ot the row oi' sweater fabric loops that are hung .troni the looper' points. The wheel m is then swung into the operative pos1tion shown in Fig. 2. Rotation of the looper is then started. Those looper points which have pierced the tape 30 operate to pull the tape through the tension device tangentially over the pins "n, of the wheel m. As the looper' continues to rotate, successive looper lingers engage successive pins n and turn wheel m and at the same time successively pierce tape 30. It is also possible to arrange the mechanism so that the looper points do not directly engage the pins, but turn the wheelby the lirictional engagement between the tape and the pins. The operation continues until there is impaled on the looper points a length of tape equal to the length oit the row of loops that are engaged with the looper points; that is, until a strip of reen-forcing tape extends across the sweater along the desired entire line of reenter-cement. The wheel m is then swung out oi' operative relation with the looper.

As the suspended loops of the sweater and the reeni'orcing strip 30 pass the sewing device, the needleyI thereof sews the renforcing tape 30 to successive loops, as shown in Fig. t (a and f Beyond the sewing device and between the same and the wheel m, astripper. cam 'lz/ is secured to avbracket a. This cam acts to strip ofi the looper. points successive sweater loops that have been suspended from such points, together' with the parts of the reenforcing tape attached thereto, until the last loop of the row of loops andthe rear end of the attached reenforcing tape are stripped off the looper, thereby entirely freeing thereenforced sweater. v

Fig. 4t (c) illustrates a row of sweater loops extending at right angles to the plane of the reenforcing strip 30 and indicates the manner in which the reenforcing strip is pernianentl y secured to the sweater;

The looper points are so spaced apart that when the sweater Vis looped thereon the i'abric is stretched somewhat along the line ol suspended loops. When, therefore, the sweater is removed from the looper and the fabric along the line of reenforceinent contracts, the reenforcing strip 30 is shirre'd or gathered to just the degree desired to enable the fabric vto stretch to the desired degree `along the line of reenforcement.

Having now 'fully described my invention,

what I claim and desire to protect by Letters Patent is:

l. In a machine for attaching reenforcing strips to knitted garments, the combination with a rotatable looper comprising peripheral points adapted to be engaged by a row of loops of. lthe knitted fabric and a rotatable wheel adjacent to the periphery of rthe looper and comprising a circular row of pins adapted to be propelled by the traveling looper points and to `be thereby rotated, whereby when a reenforcing fabric vis fed tangentially to the wheel, it will be pierced by successive looper points as the looper points propel the wheel and will be carried along by the looper in fixed relation to said row of loops. Y

2. In a machine for attaching reenforcing strips to knitted garments, the combination with a rotatable looper comprising vperipheral points adapted to be engaged by a row of loops of the knitted fabric,l a rotatable wheel adjacent to the periphery of the looper and comprising a circular row of pins adapted to be propelled by the traveling looper points and to be thereby rotated, and a tension device through which a reenforcing tape is adaptedl to travel between the looper points and pins and to be pressed by the pins over the looper points asthe looper points propel the wheel.

3. In av machine for attaching reenforcing strips to knittedgarments, the combination with a rotatable looper comprising peripheral points adapted to be engaged by a row of loops of the knitted fabric, a rotatable wheel adjacent to the periphery of the looper and comprising a circular row of pins adapted to be propelled by the traveling looper peints and to be thereby rotated, the points icing adapted to successively engage and penetrate areenforcing tape'extending between the coacting points and pins, and means at another part of the periphery of the looper to secure the tape to the row of loops as the-looper rotates. j

4. In a machine for attaching reenforcing strips to knitted garments, the combination with a rotatable looper comprisingperipheral points adapted to be engaged by a row of loops ofthe knitted fabric, a rotatable wheel adjacent to the periphery of the looper and comprising a circular row 0f pins adapted lto be propelled by the traveling looper points and to be thereby rotated, the points being adapted to successively engage and penetrate a reenforcing tape extending betweenthe coacting points and pins, means at another point in the line of travel of the looper points to secure the tape to the row of loops, and a stripper, extending along a part of the periphery of the looper beyond said securing means, adapted to strip the loops and attached reenforcing ltape yfrom the looper points.

lili? 5. In a machine for attaching reenforcing strips to knitted garments, the combina-tion with a rotatable looper comprising peripheral points adapt-ed to be engaged by a row of loops of the knitted fabric, a rotatable Wheel adjacent to the periphery of the looper and comprising a circular row of pins adapted to be propelled by the traveling looper points and to be thereby rotated, and

a lever carrying said Wheel and adapted to 10 be operated to move said Wheel into and out of operative relation with the looper.

In testimony of which invention, I have hereunto set my hand at Philadelphia, Pennsylvania, on this 4th day of June, 1927.
