SEWING-MACHINE ATTACI-TMENT Application filed February 23," 1827-. 'Se rial No. 170,323;

This invention relates to an attachment for a sewing machine, the general object of the invention being to provide means actuated by the reciprocatory movement of the needle carrier to form loops in yarn or the like and to so position the loops that they will be sewn to a fabric by the needle of the machine which operates in the ordinary manner.

This attachment can be used for forming rugs by placing the rows of loops close together and it may also be used for decorating dress goods and the like.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. I

In describing my invention in detail, -ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, andin which:

Figure 1 is a view of a portion of a sewing machine showing my invention in use.

Figure 2 is a view of the opposite side of Figure 1.

Figure 3 is a perspective view of the device itself.

Figure 4 is a view showing how the loops are sewn to the cloth.

Figure 5 is a sectional view on the line 55 of Figure 4.

Figures 6 and 7 are horizontal sectional views showing how the loops are formed.

In these views, 1 indicates an angle-shaped member which is adapted to be substituted for the presser foot of a sewing machine, the vertical portion of said member 1 being formed with the hooks 2 which embrace the presser foot post A of the sewing machine and receive between them the set screw a so that the device is attached to the post in the same manner that the presser foot was attached. By changing the shape and position of these hooks, the device can be made to fit various makes of sewing machines. The foot part 3 of the member 1 is provided with a notch 4 in its front part through which the needle passes anda spring strip 5 is fastened to the'rearof the vertical part of'th esaid member 1 and extends at an angle across the foot part 3, the free end of the spring being provided with anxoffset part '6 formed by bending the spring twice and this offset part is adapted to engage a stop projection 7 formed on the foot part adjacent the slot 4. This arrangement will hold the bent part of the spring just beyond the inner endof the notch, as clearly shown in Figure 3. A plate 8 is pivoted to the vertical part of the angle member and the. said plate is provided with a recess 9 for receiving a part'of the needle carrier B of the sewing machine so that the plate will be rocked by the reciprocatory movement of the said needle carrier. The lower part of the plate is formed with an arm 10 which is of angle shape and has its lower part broadened and bent'into a U-shaped piece 11 which has an eye 12 at the lower corner of its inner limb.

After the device has been placed on asewing machine, yarn or thelike is threaded through the eye 12, with the end of the yarn passing through the notch 4 so that it will be sewn to the cloth G or other fabric by the sewing machine when the same begins to operate. As" the plate 8 is rocked back and forth by the reciprocatory movement of the a needle carrier, the U-shapedmember 11 will form loops in the yarn, as shown at D, and as these loops are brought above the notch by the U-shapedv member, the needle will pass through portions of the yarn and thus sew theloops to the cloth. The spring 5 tends to move the loops to the right so that the loops will extend in the same direction and as the U-shaped member approaches the notch, it will push the spring back out of its way. As the U-shaped member moves backwardly, it will reeve a section of the yarn, as shown in Figure 6, and then as it moves forwardly, it will loop this part, as shown in Figure 7, and the outer limb of the U-shaped member will help the inner portion to move the loop forwardly into sewing position, the loop being prevented from folding to the left by the spring 5.

From the. foregoing it will. be seen that I have provided simple means for forming yarn or the like into loops and permitting the loops to be sewn to a cloth or the hke by a sewing machine. By placing the rows of loops close together, a rug can be formed and when this is done, the loops Will stand practically' straight. By placing the v:loop s n single rows or otherwise arranging. theloops, they can be used as an ornament foruardl'fiss or other garment or, article. v

It is thought from theforegoing description that the advantages and nevelrfeaturesofmy invention Will be readily apparent.

I desire it to be understood thatgIv may m ke changes in the construction and in the combination and arrangement-ofthe several parts; provided: that such changes -fall i within the scopeof thegappended, claim..
