12 Claims. :1 rlhis invention appertains to sewingmachines, and more particularly to `machines ofthe `type utilized for sewing labels or other `fabricgpieces on garments and the like.

@ne of the primary objectsof my invention, is to provide a novel attachment' for `sewing 4machines for effectively holding the label securely on a piece of goods or on a garment during the sewing of the label in place, whereby a `duiolr and neat job may be accomplished.

Great difficulty has been experienced in holding labels in place` during the `sewing operation,

`and in all of the holders with whichI amsfamiliar,

the holder is ,lifted off the label and moved out of the way of the needle during `the completion of the sewing at the end of the label. This `allows the unheld part'of the label topucker (particularly if the garment is made of .knitted-material) during the finishing of the sewing operation.

4a label-holder embodying a presser foot-which effectively engages the label over the greater part ofthe area thereonleaving only the margin of the label exposed for sewing, whereby the label will lie fiat and smooth over its entire face.

A still further important object of my invention is to provide means for automatically `governing the stroke of the carrier orlslide plates on the long and shortsidesof the rectangular labels, whereby a uniform `stitch can be `made entirely around rectangular labels.

A still further important object of myiinventilon is the provision of novel means for operating the slide plates in a novel manner from a single feed wheel to obtain `a compactand durable construction. i

With these and other objects `in view,.the.in vention consists in the novel construction, @arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in theaccompanying drawings, in which drawings: A

Referring to thedrawings `indetail, wherein similar reference characters `designate `corresponding parts throughoutthe several `Viewsp the letter S` generally indicates Ya `sewing machine, which can `be of the 4general `character shown and described in the lpatent `to Allen :et al. Non 1,319,450, issued` October 21, 1919.

Hence, the machine 4comprises a frame including a bed .plate `Ill from which rises the hollowstandard I I. The-upper end of thezhollow standard lI I has formed thereon the laterallyextending tubular arm I2, which terminates infa hollow head I3.

As herein represented, `the stitch-forming mechanism comprises an `eye pointed `needle tif-ll carried by theneedlelbarl. lThe needle bar I5 is reciprocated through any suitable mechanism I6 from the main drive crankshaft I1. This crankshaft l1 is mounted in suitable bearings I8 and l9'in the lateral arm l2, and the shaft protrudes through the arm and is provided with loose and fast pulley wheels 29 and 2l, and a belt 22 is adapted to bershifted from one pulley to the other. The belt 22 can be driven from any preferred drive mechanism. Formed on the crankshaft l1 is a crank 23, and this crank has connected therewith a pitman rod 24, which drives in any preferred way the shuttle-operating shaft 25 (see patent above mentioned).

Arranged on the bed platev i9 is a longitudinally extending slide plate 26 and a transversely extending slide plate 21. These plates 26 and 21 are arranged at right angles to one another, and the longitudinal slide plate 26 has its longitudinal edges beveled, as at 28, and mounted in suitable guide tracks 29 carried by the bed plate le. This longitudinal slide plate 26 has also formed therein a longitudinally extending slot 39 for the needle I4, as will be later more fully described.

The transverse slide plate 21 has its longitudinal edges beveled, as at 3|, and mounted in guide tracks 32 fastened on the longitudinal slide plate 2E. Thus, the transverse slide plate 21 can move with the longitudinal slide plate 26, and also transversely of the longitudinal slide plate. This transverse slide plate 21 is provided with an enlarged opening 33, which 'corresponds to the conguration of the label or patch to be sewed, and this opening 33 can be of a size just slightly greater than the label. The needle bar l reciprocates constantly at one point, and the slide plates 25 and 21 form means for carrying the garment with the label in a rectangular path during the sewing operation. The means for operating the slide plates will be later described.

Naturally, the label and the garment must be securely held on the slide plates, and in order to hold the garment firmly in place at all times during the label sewing operation, I provide my novel clamp or garment holder 35.

My clamp 35 includes a circular or like disc 36 having formed therein a central opening 31, which corresponds to the opening in the carrier slide plate 21, and the disc is adapted to t down on top of the garment or fabric, so as to hold the fabric on the slide plate, and the disc 36 travels with the slide plate 21 the Weight of the clamp 35 is utilized for holding the same down against a garment. The disc has formed therein an annular raceway 38 for receiving a bearing supported ring 39.

From the construction so far, it can be seen that the ring 39 is free to rotate in the disc, and friction between the ring and the disc will be reduced to a minimum. The free movable ring 39 can be held against accidental displacement from the disc by the use of a removable retaining ring 49. The retaining ring 49 is connected to the disc 36 and extends over the upper face of the movable ring 39, and the movable ring 39 can be rabbeted to receive the retaining ring 49. This movable ring 39 supports the inwardly directed bracket arm 4I, and the inner end of the bracket arm is provided with a vertical bearing or guide Sleeve 42 for the stem 43 of the presser foot 44, which constitutes the label-holder per se.

The presser foot 44 is of the same configuration as the label to be sewed, but is of a size slightly less than the label, whereby when the presser foot is in engagement with the label,

only the marginal portion of the label Will be exposed for sewing. The Weight of the stem 43 and the presser foot 44 will aid in connection with other mechanism to hold the same down on the label, so that the label will be held in place. If

desired, however, the weight .of the presser foot and stem can be used solely for engaging the label. The presser foot can be forcibly raised and lowered by means which will be later described.

The needle i4 lies directly in back of the bracket arm 4l, and, consequently, during the advancing of the label and the garment by the slide plates 26 and 21, the needle guard sleeve 55 (which will be later described) merely pushes against the bracket arm, and the bracket arm is easily advanced in front of the needle, in View of the fact that its carrier ring 39 freely rotates in the disc 36. Consequently, it is never necessary to lift the presser foot out of engagement with the label until the label is completely sewed. The bracket arm 4l will hold the presser foot 44 centrally of the clamp 35.

In order to prevent injury to the needle during the reciprocation thereof and injury to the bracket arm 41,a tubular guard sleeve 45 is placed about the needle I4 and the needle bar l5, and the upper end of the tubular guardsleeve is fastened to the sewing machine head I3.

As my machine is particularly useful in sewing rectangular labels, the presser foot 64 in the present instance travels in a rectangular path, and in order to prevent turning of the presser foot during the travel of the goods-holder or disc 36 and the presser foot 44, the upper end of the stem 43 of the label-holder has rigidly secured thereto a guide plate 46, which is received in the master guide 41. This master guide 41 is also of a rectangular shape, and its inner edge is grooved to receive the guide plate 46. A bracket 48 is utilized for connecting the master guide 41 with the sewing machine slide bar 49. The sewing machine slide bar 49 can be raised and lowered manually in any preferred way, and this slide bar 49 can form a part of the sewing machine.

" Thus, it is merely necessary to raise the slide bar 49 when it is desired to move the presser foot 44 above the label, whereby to facilitate the placing of a label to be sewed on the garment or to permit the removal of the garment and a sewed label.

Obviously, the garment-holder or disc 36 also must be elevated during the placing of the garment or piece goods on and oif the machine, and the disc 36 can be raised and lowered in different manners.

As shown, a laterally extending arm 59 is carried by the disc, and this arm is rockably mounted intermediate its ends on a loose pivot pin 5I carried by a bearing bracket 52, which can form a part of the sewing machine. The pivot pin 5l operates in a longitudinally extending slot 5l' formed in the arm 59, and, consequently, the arm 56 can slide and turn as the clamp or garment holder 35 moves with the garment and the slide plates 26 and 21. If preferred, the bearing bracket 52 for the arm can be mounted directly on and carried by an extension of the slide plate 21. The free end of the arm 55 extends under a crankarm 53 formed on a rock shaft 54. The rock shaft can be manually actuated through the medium of a pedal (not shown). This rock shaft can also be employed for severing the thread above the shuttle after sewing the label. However, this forms no part of the present invention, and the same has not been illustrated, However,

S iiiol operation of the rock shaft and downward movement of the crank53, the forward end of the arm 59 will be raised, carrying the disc 36 therewith above the garment and label.

When the clamp 25 is raised and the presser foot 94 is elevated, the garment can be quickly removed from the machine, and a new garment can be placed over the slide plates. As soon as the garment is in correct position, the clamp 35 is lowered onto the garment, and the label is placed within the opening 31 of the disc. i

i The slide bar 49 is now lowered, so that the presser foot il will engage the label. Only the margin of the label will be exposed, and the needle 14 travels in the space between the walls 33 of the slide plate 21 and the marginal edge of the presser foot dll, and, consequently, the periphery of the label will be sewed tight to the garment without wrinkling or puckering. As the bracket arm l moves in advance of the needle, the label is firmly held throughout one hundred per cent of the sewing. Due to the fact that the opening 33 in the slide plate 21 forms a pocket for receiving the presser foot, the garment, upon receiving the label, will be forced into the pocket, and, hence, firmly held.

In accordance with my invention, I provide an automatic means for regulating the movement of the slide plates which carry the label and the garment.

My automatic means includes the feed wheel 55, which is secured upon a shaft t. This shaft 56 is rotatably mounted in suitable bearings carried by the bed plate ll and the lateral hollow arm l2. The feed wheel 55 is rotated through the medium of a ratchet wheel 51. The ratchet wheel 51 is advanced in one direction in a stepby-step movement through the medium of a ratchet dog 58 carried in an arcuate path back and forth through the medium of a rock arm 59. This rock arm 59 is actuated by a pitman 69, and the pitman 99 is actuated from a rock shaft El. The rock shaft 6I is, in turn, operated by a pitman 62. This pitman 92 is connected with a crank 63 on the rock shaft 5 l.

The mechanism for turning the feed wheel 55 from the ratchet wheel 51 and the mechanism for turning the ratchet wheel in one direction from the rock shaft 6I is shown and described in detail in the Allen et al. patent heretofore mentioned, and, hence, this mechanism is not shown or described in detail. The pitman rod 62 is provided with a strap Sii, which extends about a cam 65 on the main operating shaft I1, and, in accordance with my invention, I provide means for varying the throw of the cam 65 at different times, so as to vary the sweep of the arm 59, whereby to control the movement of the ratchet wheel and, consequently, the distance of movement of the feed wheel 55.

The means for varying the throw of the cam S5 will now be described. The upper end of the shaft 56 has connected therewith a wheel 56, having a cam groove 51, which receives a roller stud 68. This roller stud 68 is carried by the outer end of one arm of a bell crank 89, and the bell crank is rockably mounted at its angle on a pivot pin 19 carried by a part of the hollow arm l2. The outer end of the other arm of the bell crank 69 has pivotally connected thereto, as at 1|, a push rod 12 slidably mounted in a guideway 13. The push rod terminates in a yoke 15 carrying roller studs 15 for engaging a push collar 15. The push collar is mounted directly on the main shaft l1 and bears against a crosspin 11 slidably 6 mounted in a diametrically extending slotV 18 formed in the main shaft. The main shaft I1 at this point is formed hollow and slidably receives an operating bolt 19, which has its forward end beveled, as at 80, for actuating and operating against the smooth end of an adjustment screw 8| carried by the cam 65. i

By referring to Figure 8, it can be seen that the bore of the cam 55 is formed relatively large, so that the cam can be shifted diametrically across the shaft l1 to vary the throw of the cam, and the cam carries a spring-pressed stud S2, which normally holds the cam in conjunction with the screw 8l and the bolt 19 tight on the shaft.

The crosspin 11 extends through the bolt 19.

and is movable therewith, and the crosspin is normally held rm against the push collar 16 by means of an expansion coil spring 83 placed about the shaft I1 between the crosspin 11 and a wear disc 84, which, in turn, engages the cam 55 and the cam strap 5d. The cam is carried by a cam wheel support 85, which is keyed to the main shaft l1 for rotation therewith, and the cam at one side is provided with an arm 86 connected by a pivot bolt 81 with its support 85. The opposite side of the cam carries a similar arm 88, provided with an arcuate slot 89 for receiving a guide pin 99 carried by the cam support 85. The throw of the cam 65 is at right angles to the guide stud 9D, and, consequently, as the cam is moved outwardly, the arm 88 will ride on the pin 99.

The wheel 66 having the cam groove 61 travels one revolution for each complete label sewing, and, hence, the groove 61 is divided into quarters representing each label side. When the long sides of the labels are reached, the roller stud 68 follows the indentation 61 of the cam slot, and, consequently, the bell crank 69 is rocked for forcing the push rod 'l2 away from the cam 65. This carries the push collar 16 away from the cam, due to the spring 83. Likewise, the bolt 19 will be carried away from the cam by the spring, and as the beveled face S0 of the bolt rides away from the screw 8|, the cam is permitted to move inwardly toward the shaft, which decreases the throw thereof. A decrease in the throw of the cam 55 results in decreased travel of the pitman rod 62 and decreased movement of the arm 59, which actuates the ratchet wheel 51. Thus, the movement of the ratchet wheel on the long side of the label is materially decreased.

On the short side of the label, the roller stud 68 engages the high sides of the cam groove, and, consequently, the bell crank 69 will be rocked, forcing the push rod 12 toward the cam B5. Movement of the push collar 16 will push in on the bolt 19, and the inclined face El] thereof engaging the screw 8l will move the cam outwardly from the shaft i1, increasing the throw thereof and the travel of the pitman rod 52. This will result in greater travel of the ratchet wheel 51, and, consequently, greater travel of the feed wheel 55 on the short sides of the label. With a decrease of travel of the cam 65 for the long sides of the label and an increase of travel of the cam 65 for the short sides of the label, a uniform speed travel is obtained for the label on the long and short sides thereof.

The means for operating the slide plates 26 and 21 for carrying the garment during the label-sewing operationembodies a cam groove 9| formed in the upper face of the feed wheel 55. This cam groove 9i is of a predetermined form, and riding in the groove 9i is a roller stud 92 carried by one arm of a bell crank 93, which is rckably mounted at its angle on a pivot 94. vThis pivot 94 can be carried by the bed plate of the machine. The other arm of the bell crank is of an arcuate shape and is provided with an arcuate groove for adjustably receiving the connecting pin 95 of an operating link 96. This operating link 96 carries a slide block 91 mounted in a slideway 98 in the rear end of the slide plate 26. By adjusting the position of the pin 95 in the groove of the arcuate arm of the bell crank 93, the movement of the slide plate 26 which carries the slide plate 21, can be governed to agree with the width of the label being sewn.

Also received in the cam groove 9| is a second roller stud 99 carried by a rock lever |00. I'his rock lever is mounted intermediate its ends on a pivot carried by the bed plate and the outer end of the rock lever |00 is slotted, as at |02, for receiving an operating pin |03. This pin is also slidably received in a slot |04 formed in a push rod |05. The push rod |05 is mounted in guides |05 on the bed plate l and the forward end of the push rod carries a roller stud |01 mounted in an inclined slot |08 formed in the outer end of the slide plate 21.

The cam groove or track 9| includes a concentric portion |99 arranged adjacent the hub of the feed wheel and a similar concentric portion |0 located adjacent the periphery of the feed wheel 55. These concentric portions |09 and ||0 are arranged diametrically opposite one another and each takes up a space on the feed wheel equal to one-fourth revolution, and the ends of the concentric portions |09 and ||0 are connected by inclined portions and H2, desired, an independent cam groove for each

roller stud

92 and 93 can be formed in the feed wheel 55 in lieu of the single cam groove 9| Considering that the machine is ready to sew a label and the garment and label have been correctly positioned on the machine, upon rotation of the main shaft l1, the needle bar |5 will be rapidly reciprocated, and the feed Wheel 55 will be turned in a clockwise direction, as indicated by the arrow in Figure. 2. Hence, the roller stud 92 will ride in the concentric portion ||0 of the cam groove, and the bell crank 93 will remain stationary.

However, the roller stud 99 will travel in the inclined portion of the cam groove, which will force the roller stud outwardly toward the periphery of the feed wheel, and the rock lever |00 will turn on its pivot lill, moving the push rod |05 to the left (see Figure 2). The roller stud |01 traveling in the inclined groove |08 will move the slide plate 21 inwardly, carrying the garment, the label, and the clamp as a unit past the needle on the long side of the label, and by the time the roller stud |91 travels the distance of the slot |03, the slide plate 21 will have moved a suiiicient distance to complete the sewing of the label on the long side, and the guard sleeve for the needle bar will have pushed the bracket arm 4| of the label-holder in front of the needle. Thus, by the time the roller stud 99 travels in the inclined portion of the cam groove 9|, the sewing of one long side of the label will be completed, as stated, and the roller 99 Will then travel in the concentric portion ||0 of the cam groove, and no further movement will be imparted to the push rod |05 at this time. During this operation of the sewing on the long side of the label, the roller stud 68 of the drive will be riding in the depressed portion 61 of the groove 61 of the cam 66, and, thus, the drive eccentric 65 is in toward its shaft I1.

Immediately after this movement, the roller stud 92 will ride in the inclined portion ||2 oi' the cam groove 9|, and the roller stud will be moved toward the center of the feed wheel, which will swing the arcuate arm of the bell crank 93 outwardly, and the slide plate 26 will be fed inwardly, moving both the slide plates 26 and 21 longitudinally of the bed plate which will permit the needle to sew one short side of the label, and when the short side of the label is sewed, the pivot pin |03 will lie at the outer end of the slot |04 of the push rod |05, as the push rod will be carried with the slide plates 26 and 21 toward the front end of the machine. This position is clearly shown in Figure 2A. During the sewing of the short side of the label, the roller stud 63 will be riding in one outer part of the groove 61 of the cam 66, and the drive eccentric 65 will be forced outwardly of its Shaft |1.

Upon the next quarter revolution of the feed wheel 55, the roller stud 92 will ride in the inner concentric portion |09 of the cam groove, and, hence, the slide plate 26 will remain stationary. However, the roller pin 99 will ride in the inclined portion ||2 of the cam groove and will be brought toward the center of the feed wheel, which will move the outer end of the rock lever |96 to the right, and bring back the push rod |05 to its initial starting position. The roller` Stud |01, operating in the inclined groove |08, will move the slide plate 21 outwardly, bringing the label and fabric transversely of the bed plate, and permit the completion of the sewing of the label on its other long side.

Upon the next and nal quarter revolution, the roller stud 99 will ride in the inner concentric portion |09 of the cam groove, and, hence, the rock arm ||0 will remain stationary. The roller stud 92 will be moving at this time in the inclined portion of the cam groove, and, consequently, the stud will be forced toward the periphery of the feed wheel. This will swing the arcuate arm of the bell crank 93 toward the shaft 56, which will pull the slide plate 21 inwardly, carrying the slide plate 21 and the garment and label and label-holder therewith, which will permit the sewing of the last short side of the label. This completes the sewing oi the label and one cycle of the operation of the feed wheel, and the parts will again be disposed as shown in Figure 2.

At this time, the rock shaft 54 can be operated by the crank 53, so as to swing up on the outer end of the arm 50 and raise the clamp 35 above the work. Likewise, the slide bar 59 on the machine head can be raised to elevate the presser foot, and the garment with the completed label thereon can be removed. It is to be understood that upon the operation of the rock shaft 55| for lifting the clamp 35, the cutter (not shown) for the thread will also be actuated.

With my novel apparatus, the label is held tight down on the work during the complete sew ing thereof on all four sides, and the machine is so arranged that the stitches on the short sides of the label will be substantially equal in length to the stitches on the long side of the label.
