RUG MAKING IMPLEMENT Filed Nov. 27, 1935 ll em liiallzueqqgg ATTORNEY UNITED STATES PATENT OFFICE 2,053,111 RUG MAKING IMPLEMENT Lena Wullweber, Virgil, s. Dak- The invention relates to a rug making imple- Application November 2 1 Claim.

ment in the form of an attachment for domestic sewing machines for the manufacture of ornamental fabrics,

such as, for example, pile rugs.

The primary object of the invention is the provision of an attachment of this character, wherein the same is susceptible of use with a domestic sewing machine may be sewed to a so that coiled strip material backing and these coils severed uniformly at opposite sides of a run of tacking to the backing effect a pile surface formly created throughout fabric with twice so that the severed coils will and the tufts will be unithe manufactured the ease and speed of other similar devices on the market.

Another object of of an attachment of the invention is the provision this character, wherein the construction thereof is novel in form so that the cutting blades are susceptible of being constructed in an upright position and set in one fourth of an inch prongs to make a more even pile. ing held in a pair at one end of the opposite sides of a from the outer edge of the The blades beguide and at passageway for the needle of the ordinary sewing machine tacks by stitching the coiled fabric to a backing and in this manner an attractive and efficient rug can be produced.

A further object of the invention is the provision of an attachment of this character, which is simple in construction,

thoroughly reliable and eflicient in' readily and easily handled, confor rewinding, its operation,

light in weight, flexible venient for use with the domestic sewing machine, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction,

combination and arrangement of parts as will be hereinafter more fully the accompanying described, illustrated in drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

Figure 5 is a sectional view on the line 5-5 of Figure 3 looking in the direction of the arrows.

Figure 6 is a fragmentary transverse sectional view through a small portion of a completed rug as created by the device.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the attachment comprises an elongated flexible flat plate III which must be of uniform width for a major portion of the length slot II centrally located and extending for a greater portion of the length of said plate and provides the closed end I2 and'the mouth or open end I3, respectively, the corners of the month end being rounded at I4. This plate I0 must be made from rather flexible sheet steel having the required rigidity and strength for longevity. Cut and bent from the blank from which the plate II] is cut or formed at an open end and at opposite side edges are blade housings l5, these being arranged at right angles to the plane of the top face of the plate l0 and rise therefrom.

The housings I5 at their inner ends have inwardly tapered openings I6, the wider ends of which open through the said inner ends of the housings I5 and exposed through these openings iii are cutting blades I1, they having beveled cutting edges l8 for shear cutting of coiled strip material I9 such as trained about the plate III. The housings I5 at the openings I6 are formed with nibs 20 which constitute stops for the blades IT to prevent the possibility of these working out of the housings I5 when confined therein as is clearly shown in Figures 1 and 3 of the drawing, there being nibs in the lower inner wall of the blade housings with corresponding slots inthe plate III for holding the housings firm when in operation. The coiled material I9 is wrapped about the plate I0 and beneath this plate is arranged a fabric backing piece 2| so that the coils I9 prior to severance thereof can be tacked by stitches 22 created in the operation of a domestic sewing machine. The stitches in mg thereof follow the slot II in the plate In as the needle is guided through the slot when the sewing machine is being operated. The end of the plateJ 0 remote from the housing I5 is formed with a finger engaging lip or tongue 2% which is upturned from this plate and is serviceable for convenient handling of the plate I0 when the same is to be drawn through the coils I9 after thereof and is formed with a the line of tackand the foot piece so as to have the needle travel through the slot H for the stitching of the coils of material I!) as wrapped about the plate ill to the backing piece 2|, this piece 2| being moved beneath the foot piece by hand. When the coils l9 have been tacked to the piece 2| the plate is pulled through the coils which slides the same over the blades I! for the severing of the coils one fourth of an inch in from the folds 24 thereof with the result that an even pile fabric is produced.

The housings I5 at the outer ends thereof are closed by a tiny cut in folded over metal fiap- 25 and by the openings of this flap, which should spring into position, the blade I 1 within the housing l5 can be removed for the placing of a new blade therein.

It is desired to inset the housings I 5 one fourth of an inch from the opposite outer sides or longer edges of the plate H) to bring the blades [1 into shearing position one fourth oi. an inch in from the folds 24 of the coils 19 of material about the right angles to the top face of the plate.
