SEWING AND GATHERING- MACHINE.

Specification of .Letters Patent.

Application filed August 31, 1904.

Patented Aug. 3, 1909. Serial No. 222,795.

To oiwhom it 'may concern:

Ie it known that I, Janine It. illoriurrr, a. citizen of the United States, residinO at Chicagoin the county of Cook, State ot Illinois, have invented certain new and useful Iniprovements in Sewing and Gathering Machines, of which the following is a descrip tion, reference being had 'to the accompany- .ing drawing and to the letters of reference 'marked thereon. `My invention relates to an improvement.

' in sewing and gathering machines, and par ticularly to the mechanism for supporting and operating the gatherer or auxiliary feedi ing device.

The invention is herein shown applied topa machine forgathering a piece of fabric, which is to be secured between two folded bands, as, for instance, in sewing the bands on knitted drawers. y

The invention consists ,in a novel mechanism for supporting and operating the gathv ering or auxiliary feeding device, and in the manner of arranging the same in combina-v tion with the stitch-forming mechanism presser foot of a sewing machine..

It also consists .in the matters hereinafter described and referred to in the aliipended claims.

The invention is illustrated in the accompanying drawings, in which, n

Figure 1 is a 'front perspective view of the head of a Sewing machine, having my invention applied thereto; Fig. 2 is au end view; Fig. is a perspective view from the opposite quarter from Fig. l., the guides beingv omitted; Fig. el is al detail view of the adjustn ing block; Fig. 5 is a detail section,'showing the manner of pivoting the bar which sup- -ports the gathering or auxiliary feeding `device; Fig. 6 represents perspective View of the throat plate feed dogs-and lower band guide; Figs. 7 and 8 represent perspective views of the parts of the lower band guide; Fig. 9 is a side view illustrating the manner of adjusting the gathering blade forward and back; and Fig. lO is a perspective of a piece of fabric sewed on this machine.

rIhis invention has been particularly de signed for gathering or feeding in a strip of knit goods between two bands7 thus puckcring the same, so that when the stitches are will be understood, however, that while this is, in eli'ect, an auxiliary feeding device, the mechanism which operates the saine may be applied .for operating a ruliling blade, and I wish to claim the same broadly.

In these drawings, A represents a portion of the cloth plate of a sewing machine, which embodies as its stitch-forming mechanism two needles a, a, set at considerable distance apart, and cooperating with complemental vstitch-forming mechanism (not shown), to make two rows of stitches. These needles are carried en a suitable needle bar B, and C is the presser bar carrying the presser foot As shown this machine is fitted to sew folded bands I), E, to a knitted fabric-F, the upper band D being fed from above and guided beneath thc presser foot by the eXtenthe screw c, which screw is also utilized tov hold in position the adjustable edge guide K for the knitted fabric F.

I do not herein claim the arrangement of he various guides, as these forni the subject matter of another application. i

The present invention relates especially to [he nie-ans for feeding or gathering the knitted .strip whiclris to be united to the bands, su that after it has been sewed, the knit goods will not be stretched in the. direction ot' the bands. .lt will be understood then that this particular feature of the invention is, in eti'ect, an auxiliary feed, acting in conlpinction with thercgular feed dogs j', f, but

in advance thereof, and aheadof the needles.`

it will be also understood that the operating device 'foi-this feature may be'applied for operating a regular ii'illiing mechanism.

L represents a toothed plate, attached to passed through the various thicknesses of i a suppori lil. pivoled ou the arm, aud norgoods, and the knit goods when sewed benially kept il; cugujrczneni with (he laln'ic -by a spring z. The forwardly projecting wire g attached to the blade L is to raise it vertically as the presser foot is raised above thel work plate. The upper end of the arm N is adjustably secured by slot and screw i kand c, to the member l, clampedupon the lower end of the rod O, which rod is set at an incline lo the needle bar, but passes through a sleeve P pivotally connected to the end of the block m, attached to andinoving with the needle bar. This rod or bar O is clamped by a screw u in the opening in the block Q, having a. stud'o formed integral with it, and pivoted to the bracket R. This bracket is adjustable by set screw andslot Pfg, onl the upper lug on the. head of the machine. It will be seen that in the operation of the needle bar, the sleeve l?l on the end of the block m slides up and down on the rod IO, but as the latter is set at an inclination, it will be caused to swing on its pivot and thus operate the blade L. By'adjusting the bracket R and the block `m to accord therewith, it will be seen that the angle of inclination of the bar or rod and therefore the amount of movement of the blade L may be varied and by justed nearer to or farther from the needle.

The blade L is set in advance of the forwai'd needle with its inner edge about in line with the center of the space between the needles, so that the gathered or puckered strip-is not caught by the iiuier needle, but only by the outer one.

Having thus described my invention, what I' claim as new, and desire to secure by Letters Patent, is

1. In a sewing machine the combination with stitch-forming mechanism' including a needle bar and vmeans for reciprocating the same, a block or member rigidly secured to said. needle bar, a slee\f'e.pivotally connected Ato' said block or member, a bar passing freely through said sleeve or member, a bracket to which said bar is adjustably connected, said connection between said bracket and bar being located relative to the sleeye carried by the needle vbar so that said bar is inclined to the axis of the said needle bar and a feeding or gathering device carried by and operated from said bar;` substantially as described. f V

2. In a` sewing machine this combination with stitch-'forming mechanism including a needle bar and means for reciprocating the same, a block or member rigidly secured to saidneedle bar, a sleeve pivotally connected to said block or member, a bar passing freely through said sleeve or member, a bracket to which said bar is adjustably connected, said bracket being adjustably connected to the head of the machine, said connection between said bracket and said bar being located relative to the sleeve carried by the needle bar so that said bar is inclined to the axis of the adjusting the arm N, the blade may be ad said needle bar and a feeding oi"gatliering device carried by and operated from said' bar; substantially as described.

'3. A sewing machine including in conibination stitchforining mechanism comprising a needlebar and means for reciprocating the same, a bracket secured'to the head lof the machine, a bar pivotally supported by said bracket, said pivotal support beingr s0 disposed that said bar is out of parallelism `with theneedle bar, means carried by Said needle bar and freely engaging said first named bar, an arm rigidly secured to the lower end of said bar and a gathering device supported by said arm; substantially as described. Y
