Still another object of our invention is to provide a pair of ruiiling blades of the type specified having ruflle-producing end portions bent towardeach other and guided, preferably by the terminal ends of a rigid folding and guide member for the edges of the trimming strip and the edge of the quilt or the like, to cause such blade ends to engage and simultaneously ruflle opposite edges of a suitable strip of trimming material during the sewing thereof to opposite surfaces of the edge of a quilt or the like.

With thes and other objects in view, the invention comprises the combination of members and arrangement of parts so combined as to coact and cooperate with each other in the performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which- Fig. 1 is a fragmentary view in end elevation of a sewing machine head embodyinggour doubleruffling attachment showing the needles in r'ais'ed position and the ruffiing blades in retracted position;

Fig. 9 is a section on the line 9--9 of Fig. 2.

Referring now to these drawings which illustrate a preferred embodiment of our invention, we areenabled to produce an article such as theq'u-ilt I shown in Figs. 6, 7 and 8 having a combined edge-binding and trimming member -'2 composed of a single longitudinallyfolded strip 3 of trimming material provided along its opposite edges 4 and 5 with rufile-pleats I5, I sewed to the-opposite surfaces I I of the quilt l at the edge thereof whereby we produce a quilt or the like having a binding member that encloses and binds its edge and provides an ornamental rufile'd trimming '8 for opposite surfaces thereof. The ruffled pleats 6, 1 on opposite surfaces of the edges are of equal and uniform depth on 'both edges so that during a sewing to the quilt of 'a considerable length of such pleats, we will avoid any substantial unevenness of the travel of opposite edges of the trimming strip that would cause distortion or uneven tension or pulling of the material at the middle or body-portion 9 of the edge-encircling trimming memberbetween the rows of pleats which is ornamentally fluted by the pleats.

The mechanism for producing the article 1 comprises a head ID of a conventional sewing machine having a needle-bar I I carrying a needle I2 and a presser-foot bar I3 carrying a presser foot I4, both of which are actuated by*conventional mechanism not shown. The presser foot presses and holds 'the material in engagement with a set of feed dogs I5 also "actuated in the usual manner by conventional mechanism not shown.

The sewing machine head I0 is provided with a conventional horizontally disposed ruflle shaft I6 mounted in bearing arm IB extending laterally from the head Ill, and we mount on the shaft It a binding and ruffling attachment that will during a sewing operation enable the simultaneous binding of the edge of a quilt or the like and produce ruffiing pleats of opposite side edges of a single folded strip of trimming material to provide a trimming surrounding such edge to function both as an edge-binding and as an ornamental rufiled trimming. In our preferred embodiment, we preferably mount in an inwardlyoffset position a ruffling-blade lever I! which, as shown, is adjustable vertically in a sleeve H and has an offset collar II fast on the said shaft IS.

The inward offsetting of the lever I6 provides more space at the outside thereof for our bladeconnecting device which, in the preferred embodiment shown, comprises an oscillatable yoke member 18 having arms Ili I8 extending angularly to each other from an intermediate pivot-bearing I8 which is pivoted on a block or collar I9 adjustable vertically on the lever H. In the embodiment shown, the 'outer ends of the yoke-arm's I8 I8 have mounted therein and carry horizontal extensions or blades- positioning rods 25, 20 the outer ends of which extend transversely across the path of movement of the quilt edge and the trimming material and are provided at such o'uter ends with pairs of attaching screws 2I and 22, by which a pair of ruining- blades 23, 23 are mounted on the rods 2D, 253 to extend transversely thereto in substantial parallelism and alignment with the said path of movement of the quilt edge and trimming material. Said pair of blades 23, 23 are resilient and bent at their outer ends to extend toward a common plane "and are positioned to move in contact with u per and lower terminal plates 24, 24 of a channeled guiding member 24 having a middle guide-channel portion 25 'for the reception of the edge 26 of the quilt I and a U-shaped channelled portion 21 fitting around said channeled portion 25 and having leg portions 21 27* extending on opposite sides thereof. A channel is formed between the inner channelled portion 25 and the outer channeled portion 21 and the channel so formed received a folded strip of trimming material 3 which has been initially folded between its edges by any suitable means and then passed through a lateral or side extension 29 of said U-shaped channel member 24, and in accordancewith our inven'-" tion, said terminal ends 24 24 are utilized as guides for the movement of the resilient upper and lower rufiiing blades 23, "23 Due to the resilience, positioning and mounting of said 'ruffiing blades, they are adapted to move toward each otherQand'are guided by said channelled-portion ends 24*, 24 to move into rufliing contact with the opposite edges of the trimming material fed through said channel between the portions 2'5 and 2 1 "and through the outlet at the ends'of said terminal portions 24 24 The rufiling blades are preferably for'me'd of relatively; flat blade-attaching; spring members 23?, 23 and, reverselyo-bent bladeesections 23 23F'i'which are each provided at-stheir terminal endswith fine teeth 23 as shown in Fig." 2,;

As shown, the lower terminal end 24 extends to'a' line s-adjacent to the bottom of a shallow groove iifl in the topjsurfaceof the sewingmachinetable t and theouter end 23? of the'lower rufiling blade operates in said groove 30 and reciprocates -between the bottom thereof-and said terminal end 2.4 ,,of the said guidemembei' 24.," It will be seen that the pair of rufiling blades are mounted for reciprocable movement conjointly toward and away from a common plane and adapted, during a machine stitching operation for sewing to opposite surfacesadjacent to the edge of a quilt or the like the opposite edges of a folded trimming strip, to simultaneously ruflie such opposite edges of the folded trimming strip and thus to provide on the edge of the quilt or the like a combined edge-binding and doublerufiled trimming: that the pair of rufiiing blades are reciprocably movable conjointly toward and away from a common plane extending adjacently above a sewing machine base and the feed dog thereof combined with means for moving and guiding said blades to move at a position above said feed dog and below a presser foot to provide on both surfaces of a guided edge of a quilt or the like ruflied pleats of a trimming strip, and that the attachment of the type specified is adapted to produce ruflles or pleats of equal Width at opposite surfaces of the guided edge of the quilt or the like, and also that we provide a mounting means for said blades which will enable both blades to be moved by a common rufiling blade lever and to be moved similar distances on each operation of said lever and to provide a mounting means preferably comprising an oscillatory yoke pivotally mounted between its ends on said rufliing-blade lever and having arms through which the pair of rufliing blades are conjointly reciprocated by said rufiling blade lever through equal distances to produce uniform ruflie pleats on each operation.
