To all whom it may concern:

. lVestfield, in the'countyof'Union and State Be it known that I; ALBERT H DE Von,

a citizen of the United States, residing at of New J ersey, have invented certain new ,and useful Improvements in Article-Presenting Means for Sewing-Machines, of which the followlng 1s a specification, reierence being had therein to the accompany ing drawings.

This invention relates to an improvementin devices for attaching small articles, and

it has for its object-'toprovide simple and .e'fiective means for successivedelivery of such articles to the fastening means such as the stitch-forming mechanism of a sew-1 .ing. machlne. The invention is designed more particularly to provide means forp-roducing automatically a tape composed of overlying strips of fabric with interposed dress-weights preferably predetermined intervals.

In its preferred form, the present improvement is embodied in a sewing machine comprising stitch-forming mechanism and a work-support having edge-guides on opposite sides of. the stitch-forming mechanism to afford a lower-strip guiding channel above which is disposed an upper stripguide sustained by the prsser-foot. Upon the work-support and in advance of the stitch-forming mechanism is preferably mounted a :yieldingly sustained segmental runway having in its delivery end an arpoint above and in close proximity to which is sustained the lowerv end of an article holding magazine swinging in a path concentric with the axis of curvature of the runway. Pivotally connected with the magazine is a spring-pressed pushing finger having a depending projection or spur adapted to engage the edge ofan article deposited in said cavity ofthe-runway toadvance it into the range of action of the stitch-form ng mechanism lntermediate the upper and lowerstrips 0t fabrlc delivered to the stitch-forming mechanism by the respective guides.

The upper end of the magazine is prefer- 'ably flared to form a funnel into which are directed by a suitablechute'articles deliv- "ered from a slowly rotating peripherally apertured hopper containing a supply of such articles. Thehopp r preferably de secured therein at ticle cavity open adjacent the stitching rives its operative movements from a connection' with the rocking support of the magazine' 1 In the accompanying drawings, Figure 1 is a frontsi'deelevation of a portion of a sewing machine embodying the present improvement; Fig. 2 an end elevation and Fig. 3a plan of thesame. Fig. & 1s a perspective view representing the parts of the improve- 1 merit adjacent the stitching point. Fig. 5 isan elevation similar toFig. 2 but viewed frointheopposite end of the machine, and

:with the 'bracket-arm'and bed-plate in transverse section.

Fig.6 is a detail sectional view representing the hopper rotating means; Fig. 7 is a'perspective view of the under side of the presserdoot'. Fig. 8 is a. viewrepresentlng a section ofthe weighted tape with one of its component strips raised at one end to expose the arrangement of the parts.

I The machine represented in the drawings isvof the well-known Singer No. 41 class, comprising the bed-plate 1 andoverhanging bracket-arm 2 in the head 3 of which is journaled the reciprocating needle-bar 4 carrying in the present instance the multiple needleclamp 5 provided with three needles 6 arrangedin a line crosswise of the direction of feed.

Mounted in the head 3 rearward of the needle-bar is the presser-bar 7 having secured upon its lower end the shank S of the presser-foot whose foot-plate 9 contains the usual needle-holes 10. The resser-foot is provided in its lower face rearward of its forward end \V1tl1 a strlp-gulding channel 11 within which is the deeper article-guiding channel 12. The foot-plate is provided above its forward notched end with the arched guide-loop 13 over which the upper stripis led to'theupturned end of the channel 11 in its passage to the stitching point.

Upon the bed-plate is secured the usual work-plate or support 14 which is provided with the laterally spaced edge-guides 15 having lateral extensions '16 secured in positi'on by screws 17 and affording a strip- Secured upon the work-plate 14 by screws 19 is the arched foot 20 of an upwardly and forwardly projecting spring arm 21 havmg an offset portion 22 affording a raised seat to which is secured by means of the screw 23 the upper end of a segmental raceway 24 having in its upper face ad acent the lower or delivery end the article-cavity 25 and having in its extremity the notch 26 adjacent the stitching point. Extending forwardly from the closed end of the cavity 25 is thepusher clearance groove 27.

Mounted upon a fulcrum stud 28 sustained by the bracket-arm head 3 is the hub 29 of a rocker provided with a rearwardly extending arm 30 and a forwardly extending arm 31 channeled in its outer portion to receive the inturned portion 32 of a lateral extension 33. To the outer end of the extension 33 is adjustably secured by screws 34 a flange 35 of a split collar 36 sustaining in vertically adjustable position thetubular magazine or carrier 37 for the articles to be attached. The magazine 37 is inclined laterally to avoid as far as possible obstructing the operators view of the stitching point, and is flared at its upper or receiving end to form a funnel 38 while terminating at its lower end at an inclination with its length to conform closely with the upper face of the runway 24 over and longitudinally of which it reciprocates in performing its operative movements.

Near its lower end the magazine 37 has a transverse lug 39 upon which is fulcrumed by means of the stud-screw 40 one end of the pusher-arm 41 whose body portion is curved to conform with the shape of the magazine and has at its free end the depending finger 42 provided with the depending spur or projection 43 adapted to enter the clearance groove 27 when the magazine is in retracted position as represented in the drawings. A

spring 44 secured to the lug 39 at one end and bearing at 1ts free end upon the pusherarm 41, causes the finger 42 to normally rest i upon the bottom of the article cavity 25.

stitch, or in such other spacing as may be determined upon.

Secured by a suitable angle-piece 51 to the head of the bracket-arm 1s a chute 52 whose mouth extends over the funnel-mouth 33,

or hopper 53 having its front, side open at the center and providedwith an inwardly inclined flange 54, the closed rear side 55 being provided with the inwardly projecting boss 56 journaled upon the bearing stud 57 which is sustained by the bracket-plate 58 mounted upon the bracket-arm head 3. The periphery of the hopper 52 is provided at intervals with discharge apertures 59 of substantially the size of the contained supply of articles to be fastened which, in the agitation caused by the step-by-step rotation of the hopper, are caused to issue therefrom and pass through the chute. into the magazine or carrier 37 for ultimate delivery at the stitching point. 7 i

The wall .55 of the hopper has secured to its rearward side the ratchet-wheel 60 which is engaged by the spring-pressed holding pawl 61 sustained by the bracket-plate 58, and by a spring-pressed actuating pawl 62 mounted upon a rock-lever 63 fulcrumed intermediate its ends at 64 upon the bracketplate 58 and having its opposite end connected by means of the bent link 65 with an arm 66 extending from the hub 29 of the magazine sustaining rocker. In order to prevent overthrow of the hopper under the action of the pawl 62 induced by its described connections with the magazine-sustaining rocker, an archeddrag-spring 67 is secured by screws 68 upon the bracketplate 58, its free end resting upon the wall 55 of the hopper.

Fulcrumed upon the upper end of the rock-lever 63 by means of the screw-pin 69 and spring-washer 70 is the handle-lever 71 having in its hub portion a peripheral notch 72 embracing the stop-pin 73 upon the rocklever 63. By the means described the handlelever is adapted to assume and frictionally maintain either of two extreme positions relative to the rock-lever 63, in a manner wellknown. The handle-lever carries upon its rearward face a stud 74 whose head is apertured to receive one end of a wire spring 75 having its opposite end rigidly attached to the actuating pawl 62. When the handle. lever is in one of said extreme positions the spring 75 is caused in a manner well-known to press the pawl 62 into operative engageticles such as dress-weights a in disk form,

is inserted through the open side of the hopper which may, if desired, be turned by this chute being suitably flared and rounded hand to introduce a supply into the magazine.

66 to embrace one side of the cylindrical drum A lower tape 6, preferably with inturned edges exposed upon the upper 'side isintroduced beneaththe guide-loop 18 and between the edge-guides 15 and beneath the delivery end of the runway 24; into a' position beneaththe needles; and an upper tape 0 with edges similarly turned under is led downwardly from a suitable supply spool over the guide-loop 13, within the notch in the forward end of the presser-foot and within the guide-channel therein, after which the presser-foot is lowered and the machine set in motion.

The first few stltches are preferably takenthrough the material to unite together along the margins the initial ends of the overlying strips, after which the magazine advances toward the stitching point and with it carries the pusher-finger 42 which moves the initial weight a forward within the carrier 25 and deposits it in the notch 26 of the runway and upon the lower strip with which and the upper strip it is drawn by the feeding mechanism beneath the central needle and thereby firmly stitched to and between the upper and lower strips, asrepresented in Fig. 8 wherein the central seam d is shown passing through both strips and theweights a and the sideseams e passing through the marginal henis of both strips. As the mouth of the magazine reaches extreme advance position above the closed end of the article carrier 25, which affords an articledetaining shoulder, a succeeding dress-weight drops into the latter, so that upon the retraction of the magazine the next dressweight slides backward over that so deposited and the upper face of the runway, the spur 43 of the pusher-finger 42 riding up over the dress-weight so deposited and snapping over the opposite edge of the dress-weight and entering the "clearance groove 27 provided for the purpose in readiness for the next article-presenting excursion. V I

The dress-weights are preferably made of a soft metal, such as'lead, which may be penetrated by a needle in the stitching operation; but it is evident that they may be previously formed with apertures to receive the needles, in case they are made of harder metal, or the central line of stitches may be omitted entirely, the weights being laterally confined in position by the edge seams.

It is also evident that the component strips of the weighted tape may be selvaged and unhemmed, or that one or both may be replaced by a body fabric ofthe garment to which the weights are to be applied, the work-directing means being modified correspondingly to suit such conditions.

It is evident that the present improvement is susceptible of material modification in the construction and arrangement of its parts within the scope of the invention, which latter is not to be understood as limited to the specific embodiment thereof herein shown and described.
