ing certain of such products, to provide a more deslrable and conveniently manipulated construction, to combine a duplex ruflling mechanism with a single organized stitch-forming and cloth-feeding mechanism and in a manner to give to the products, by a single operation, a more sightly and elaborate effect than is possible in connection with the earlier art.

It is believed that the present improved means is the first to produce by a single operation of a single organized stitch-forming and cloth-feedingmechanism separately directed like orunlike strips of seam secured ruffled fabrics, which improved means carrice with it features in construction making convenient to greatly vary the character of the product, all of which will appear more fully from the following description and claims when considered in connection with the accompanying drawings, in which Figure 1 is a view in front side elevation of the front end portion of one form of commercial sewingmachine supplied. with the present invention.

cross sectionof the inner radially projecting lever for transmitting movements tothe inner of the two members, together with adjustable stop block. Fig. 10 is" a view of telescopically arranged ruffling blade actuating shafts. Fig. 11 is a View of one variety of product effected by the present invention.

The present invention is shown and will be described as applied to one form of Singer commercial sewing machine, but as it relates only tothe construction and application of a multiple ruffiing mechanism, only such reference will be made to the other elements of the machine as is deemed necessary for a proper understanding of its application.

Referring to the figures, 1 represents the mainor needlebar actuating shaft 301m naled in suitable bearings formed in the bracket-arm 2, carried by the cloth-plate 2, the latter and said bracket-arm comprising the sewing machine frame, 3 an eccentric suitably secured on said shaft and encircled by an eccentric strap 4 of an eccentric connection 5 havingits lower. endfulcrumed on a stud 6 threaded into a radially projecting crank-arm 7 suitably secured upon the inner end ofa short shaft B'jOurnaled in a suitable bearing formed in a bracket 9 secured by screws, as 10, to the bracket-arm'2.

11 represents a'tubular ruifling blade actuating shaft and 12 a shaft looselymoiinted in said tubular shaft, the latter having suitably secured uponits inner end aradially projecting lever 13 provided with a slot'lfl (seeFig. 9) into which is slidably mounted an ustably secured stop block comprising the block. 15', washer 16 and screw '17, the

latter threaded into said block, ,and an adthe slideblock 27 i in the groove 21, the opposite side of said flanged' block being proi e t thre de eie tiqe sh in dotted lines only, Fig. 8, and onto said projection is threaded a winged nut 29 and beneath the latter a washer 30, and below said washer an indexing plate 31, the nut 29 acting to secure said pivot block against accidental movement in the slot 23. the pivot block 18 being of like construction except that in the latter the crank-pin 32 is employed'instead of the wing 33 of the nut 29 and the groove 14 carries a block, shown in dotted lines, Fig. 4, corresponding to block 27 shown in Fig. 8. I

As the means for operatively connecting the rufliing blades 34 and 35 with their respective actuating shafts l2 and 11 comprise a like combination of elements it is deemed suflicient to refer only to the connections for operating the ruftling blade 34.

36 represents a shaft crank suitably se-' cured upon the rufiing blade actuating shaft 12 and to said shaft crank is adjustably secured by screws, as 37, a blade actuating lever 38 provided with a pivotally secured blade carrying bracket 39 to which is suitably secured the ruifling blade 34, said bracket having formed integral with it a finger piece 40 having an opening 41 through which extends a threaded rod 42 suitably secured in a projection 43 carried by the lever 38, said rod having threaded upon it a nut 44 the adjustment of which causes the spring 45 to act onsaid finger piece to effect the desired downward pressure of the blade 34. 46 represents a horizontally arranged finger projecting from the bracket 39 the free end of which lies directly over the bent end portion 47 of the blade lifting arm 48 carried by the clothresser carrying bar 49 to, when the latter is elevated by common means including the present lifting lever 50, efiect a rocking movement of the bracket 39 and raise the rulfling blade 34 to accommodate the manual manipulation of the fabric beingacted on. From the foregoing is to be understood thatrocking movements are transmitted from the main-shaft l to the crank-arms 7 and 20 through the eccentric 3 and connection 5 and that such movements are transmitted to the levers 13 and 22 through the pivot blocks 18 and 24 respectively, and that the amplitude of rocking movement transmitted to the respective shafts 11 and 12, and accordingly, to the respective ruffiing blades 35 and 34 depends upon the adjustments of the pivot blocks 18 and 24 with respect to the aXes of the respective shafts 11 and 12.

51 represents a tape or band-guide carried by the cloth-presser 52 and in the present instance shown as a tape folding and guiding element through which the band or covering-strip 53 (see Fig. 11) is passed from the supply to the action of the needles and may be construed with or without the folding scrolls, as 54, dependent upon whether a selvage or raw edged tape or band is to be employed. 55 represents a fabric guide bracket secured by screws, as 56, to the bracket 9 and carrying at its lower end a base-plate 57 upon which is secured by screws, as 58, left and right hand edgeguides 59 and 60 respectively, and to the underside of said plate is secured by screws, as 61, a separator-blade 62 of a length and width to underlie the ruifling blades, as more clearly shown in Fig. 3.

In effecting the product illustrated the body-fabric 63 is passed between the throat or needle-plate 64 andthe separator blade 62, and the trimming fabric 65 through the edge-guide 60 and the lace trimming 66 through the guide 59.

Having thus set forth the nature of the invention, what we claim herein is-:
