To all whom it ma concern:
Be it known t at I, JOSEPHFBENCH, a citizen of the United States, residing at Voonsocket, in the county of Providence, State of Rhode Island, have invented a certain new and useful Improvement in Machines for Applying Labels or Tags to'Art-icles for the Laundry, &c., of which the following is a specification, reference being had thereinto the accompanying drawings. I
The invention consists in mechanism for automatically attaching short lengths of tape or other suitable material by means of stitches to various articles, to serve as labels or tags or for other purposes. The said mechanism is adapted, for instance, for at-,
t-aching such labels or tags to articles of -apparel or other personal use, household linen, etc., about to undergo the operations or analogous treatment, and
of a laundry or of a cleanin establishment, for attaching them to articles of apparel, or other articles of 'woven and knit goods, or of leather, or to parts of such articles, in connection with manufacturing processes.
In carrying my invention into effect I employ, in combination, devices for presentin the label or tag in proper position with re ation to the article to which it is to be attached, and holding it in the correctrelation therewith while the two are being fed in unison to the stitch-forming devices, stitch-forming devices serving to secure the label or tag .to the said article by means of stitches,.and devices for feeding the article and label or tag to the stitcht'orming de-,
' vices for the stitching. operation. In forming successive labels or tags from a continuous strip, I also employ-devi'ces for severing from a supply of strip-material a section suitablein size for a label or tag, and an automatic device for feeding the continuous strip from the supply.
A feature of the invent-ion is the com bination with the foregoin devices of driving devices adapted to be t rown into action at the will of the operator to actuate the working parts to attach a label or. tag, and arranged to arrest the action of such parts automatically as soon as the predetermined number of attaching stitches shall have been made.
The invention in its more-complete form is shown embodied in an automatic machine in the drawings, in which latter,
Figure 1 is a front elevation of the said 2, 3 and 4. Fig. 1 is a detail. Fig. 2, Sheet-- 2, is an elevation thereof from the right hand side in Fig. 1. Fig. 3, Sheet 3, is an elevation thereof from the left-hand side in Fig. 1. Fig. 4, Sheet 4, is a plan view thereof. Figs. 5 and 6, Sheet 1, respectively are views in section on lines 5, 5, and 6, 6, respectively, of Figs. 2, 3 and 4. Fig. 7, Sheet 2, is a view of the presser in horizontal section in the plane of line .7, 7, Fig. 2, on a somewhat enlarged scale. Fig. 8, Sheet 3, is a view in section on line 8, 8, of Figs. 2, 3, and 4, showing the clutch and stop-devices. Fig. 9, Sheet 5, is a face view of a portion of an article having a label attached thereto, showing the result of the action of the machine illustrated in-the drawings.
Fig. 10, same sheet, is a back view thereof.
Fig. 11, same sheet, is a sectional detail of the said article and tag on an enlarged scale.
Having reference to the drawings,at 1
is shown a convenient base or bed, at 2 the;
work-support of a sewing machine, at 3 theupright portion or post rising from'the said work-support, at 4 the overhanging arm of the sewing machine, and at 5 the head'of the said machine. nism of the machine may vary in character in practice. It is in this instance of an ordi- The stitch-forming mechanary two-thread lock-stitch type, and may be of any preferred construction, the needle being shown at (3, Figs. 2 and 3, and the needle-bar at 7. \Vork-feeding devices of suitable character are employed, the toothed portion of a feed-dog of usual kind being shown at 8, Figs. 1, 2 and 3. By means of such work-feeding devices the garment or other article to which a label or tag is being attached, and the label or tag, are advanced together in the machine as the successive stitches are formed. The supply or upper or needle-thread is furnished by a spool at 10, Figs. 2 and 4, guides for such thread on its way to the needle being shown at 11, 11, and a needle-thread take-up device being in part shown at 12.
At 13 is a presser-foot or presser, and at 14 is the presser-bar. -The said parts 13 and 14, as usual in the case of the presscrfoot and presser-bar of a sewing machine, are movable toward and from the worksupport in a Vertical direction, and are furnished with a convenient spring, as presently described, operating with a tendency to hear them toward the work-supportso asto keep the presser down upon an article re on the said support. n addition, to: the purposes of the invention, they are made movable back and forth parallel with me has of the feed. These different movements are provided for in the present embodiment of the invention by lining the presser-bar at its upper end upon a short horizontal shaft 15, Figs. 2, 3 and i, extending parallel with the arm i and above the latter and fitted to bearings which are provided in the free ends of arms 16, 16, lined upon a rocking sleeve 17, which last is fitted to bearings in the arms or brackets 18, 18, rising from post 3 and.
head The presser and presser-bar are kept normally in their starting position at the right in 1, with the presser-bar in contact with a stop-pin 21 projecting from the head 5 of the machine, by means of a spiral spring 19 surrounding the shaft 15 and having one end thereof engaged with the standard :20 rising from such shaft, as shown in 2. This spring acts with tendency to turn the shaft 15 in its hearings in the arms 16, 16, until the presser-bar engages with the said stop-pin 21, and to keep the presser-bar in such engagement. The spring above referred to, that is employed for the purpose of moving the pressenbar and presser down toward the Work-support 2 and the wort resting thereon, and maintaining the downward pressure of the presser, is in this instance a contracting spiral spring 26. lt has the lower end thereof engaged with the arni of the ina-- chine, and the upper end thereoi engaged.
with an adjustable screw 27 carried by one or" the arms 16. Lifting movement is automatically communicated to the presser-bar' and presser at the predetermined times in the working of the machine by movement of partial rotation imparted to the sleeve 17 through devices comprising an arm 22, Figs. 1, 2 and 3, fined upon the rear end of the sleeve, and a cam-projection 23, Figs. 1 and 5, upon a gear-wheel 24. Such projection extends inward from the rim 24- or the said gear-wheel toward the center of the latter, and it acts against pin or roll at 25 carried by the said arm 22. llormally, the machine stands at rest, with the said cam; projection in engagement with the said pin or roll and With the sleeve 17 and its arms 16, 16, in a position which holds the presser uplifted above the work-support so as to facilitate the insertion of an article, as 3),
Fi s. 2 and 3 and a label at a. under the presser and between it ano. "the vrorlz support. When the machine is started, the first portion of the turning movement of the gear-wheel 24.- carries the cam-projection 22-3 out of engagement With the pin or roll 25, whereupon the spring 26 acts to turn the sleeve and its arms in the CllTQCL/LOU to move the presser toward the ivorlr support, causing the presser to clamp the label and article together an against the work-support 2. The machine being in motion, stitches are made by the action of he stitch-making devices, thereby uniting label a to article 7), and by the movements or "he feed-dog 8 the said article and the label are fed in unison from right to left in 1 past the needle. is they are thus ted the frictional ci'igagement between the under surface of the p'resser and the surfaces of the label and article 7) causes the presser and presser-bar to accompany the label and article against the opposition of the spring 19, the pi'csser- )ar swinging about the axis of shaft 15 as acenter.
The presser is constructed to guide the label a into position to be stitched, and to remain in engagement with the same, holding it in place upon the article 7), until it has been attached to the latter. The devices of the illustrated machine are, in conformity with one feature of the invention, constructed and arranged to attach the label to the article by a line oil stitches crossing the width of the label, as indicated in Fi s. 9, 10, and 11. Accordingly, the presser operates to guide the label a so that as the latter passes into position to be stitched to the article it extends at right angles to the line of To this end, the presser is formed at its front side with an open notch, 36, 7, of a Width properly proportioned to the label a, the opposite sides of the said notch being continued above the presser by side walls 35, 35, upon the presser-bar constituting edge-guides for the label: It because the label is engaged in this manner with the resser, and remains thus engaged during the operation of stitching across its end, that the presser is mounted to accompany the "FOili as the latter is fed along in the machine during the stitching operation.
The label a may be of any material suitable for the purposes of a label or tag and adapted to be stitched to the article 7). Usually, I employ woven tape. For greater convenience, prefer to form successive labels or tags from a continuous strip a of material suitable for employment for the purposes labels or tags, for instance woven tape as just specified, which is conducted bysuitable guides to a point a ljacent the stitch-ma ring point. This strip is shown drawn from a roll 28, mounted upon a pin 29 carried by the standard or "upright 2G, the said roll having in connection therewith, for the purpose of preventing too free a delivery of the tape, a drag dev1ce ery of the wound mass of tape. The strip the presser once more this occurs the machlne comes to. rest as herelnafter' exas it is extended from the roll to the presser passes through guides at 33, 34, and then between the sidewalls 35:, 35, of the presserbar, it bein held in flattened condition by means of t e cross-pin 35 which extends stands at rest, with the cam-projection 23 inengagement with the pin or roll 25 of arm 22, and the presser elevated as in the drawings. The leading end of strip a having been. caused to extend a short distance below the Presser, the machine is in readiness for attaching a label to the desired article. In beginning operations, the said article 6 is entered from the. front in Fig. 1, that is, from the left-hand side in Fig. 2, in beneath the presser. As it is carried under the latter, it pushes the hanging end of the strip a in with it so that such end extends rearward beyond the position of the needle, as at a in Figs. 2 and 3, but usually somewhat to the right of such position. When, new, the machine is set, in motion, the cam-projection 23, is carried past the pin or roll 25., thus permitting spring 26 to. rock the sleeve 17 and its arms 16, 16, and move the pressr down upon the article I) and the label a which overlies the same. In its lowered position the presser holds the material. of article I) in engagement with the teeth of the feed-dog 8,
so that the latter in its movement shall oper-,
c, to feed the said article and label from right to,- left' together to theneedle. The revolution ofgea'r-wheel '24 is. so timed that as soon as the label a in being fed along with the article 'Zx has been carried trans- I versely to. the left to. the required extent with relation to the needle theca-m-projection 23 arrives again in engagementwith the pinjor roll 25 and operates through the intermediate connections totraiasmij movement to lift plained, leaving the .pre'sser 1n its uplifted position. v p A characteristic feature iirconncction with the presser is. the fact, abovere-ferred to,
' that while it is yieldingl-y prm'edfdown upon the end of the strip, '5. e. thel'a bela, and the portion of article I) underlying the same,
it. 15; carried forward in the direction of the feed, that is, from. right to left in Fig. 1, by frictional engagement with the saidstrip and article as these latter are advanced, i. 6., fed, by the action of the feed-dog. This forward movement of the Presser in the direction of the feed is essential, since the sidewalls 35, '35, of the presser-bar and the correspondii side-walls of the notch in the presser constitute edge-guides for the strip, and it is necessary thatthe guiding-means "and firmly alongside the edge for the strip should advance-in unison with the article Z) as the latter is fed, so that the label may be carried crosswise past the needle.
For the purpose of severing from the continuous strip a the portion thereof, e. label, which has been stitched to the article 5, I provide a suitable cuttendevice.
- Herein, the latter comprises a fixed blade 37,
Fig. 1, a movable blade 38, and actuating means for the said movable blade. The said fixed blade is provided upon the resser-bar. The. movable blade is fixed upon the lower end of a substantially upright shaft 39 that is mounted in bearings which are provided upon the presser-bar at 40, 40. To insure efficient cutting action, the bearings for the said upright shaft are so disposed as to cause the axis of the shaft to occupy a position that is slightly inclined out of parallelism with the longitudinal axis of the Presser-bar. The axis of the shaft leans away at its upper endfrom that of the presser-bar, in the direction of the feed, as illustrated in Fig. 1. In addition, an expanding spiral spring 41 surrounds the shaft 39 between the lower bearing 40- and an adjustable collar 42, which latter is clamped by its securing screw upon the shaft 39 in such position. as to maintain a proper degree of compression of the spring. The spring acts with a tendency to lift the shaft vertically endwise, thereby holding the upper side of the movable blade 38 in contact with the under side of the fixed blade 37. The result of this action of the spring, and the effect of the inclination of the cutter-shaft 39, are to cause the edge of the movable blade to bear closely of the fixed blade, thereby insuring perfect cutting action. For the. purpose of operating the movable blade to cut the strip a, the cutter-shaft 39 has fixed thereon an arm 43 whichis connected by a universal joint at 44 to one end of a connecting rod 45, the other end of which is connected by a universal joint46 with the upwardly extending. arm of a bell- -crank 48, Figs. 1 and 3, which is pivoted upon the stud 49 projecting from the post The horizontal arm of the said bell-crank has connected therewith one end of a contracting spiral spring 50, the other end of which is connected with the work-support 2, this spring acting to hold the movable cutterblade in its open position and the said horizontal arm ofthe bell-crank in contact with a fixed stop at 51. For the purpose of operating the cutter-device at the proper time in the working of the machine, a pin 52, Figs. 2, 4, and 5, is provided upon the rim of the gear 24. As this pin comes around in the rotation of the said gear, it engages with the horizontal arm of the bell-crank, and, pressing the same upward, transmits movement through the described connec- 4 esser? tions to the cutter-shaft 39 and the movable cutter 38 carried thereby. As soon as the pin has passed beyond the horizontal arm of the bell-crank and released the same, the spring 50 operates to restore the parts to their normal position and opens the movable cutter-blade. The reason for employing universal joints in the connections at M and 49 is the fact that while the stitching of the strip a to the article I) is in progress the resser-bar carrying the cutter-bar moves forward in unison with the strip and article, as above described, whereas the bell-crank always remains and swings in the same plane. After the cutting operation has been performed the continuous portion of the strip a is fed downward automatically to a sufficient extent to cause its leading end to project below the presser, as before, a distance sufficient to enable the same to be pushed in under the uplifted presser and across the line of stitching in beginning the operations of attaching a fresh label or tag to a succeeding article. This moving or feeding of the continuous strip down is effected by means of the strip-feeding dog 54, Fig. 1, which is constituted by a bent spring strip working at its acting extremity between the side Walls 35, 35, of the presserbar, and toothed at such extremity to engage with the strip. This strip-feeding dog is attached to the guide 34,'which latter in turn is formed upon a slide movable upon the presser-bar in the direction of the length of the latter. Thereby the said strip-feeding dog is attached to the said slide. For the purpose of operating the slide and stripfeeding dog, the said slide has connected therewith pivotally at 56 the lower end of a connecting-rod or link 57, the upper end of which is pivotally connected with an arm 58 fixed upon a rock-shaft 59 extending through the sleeve 17, and having fixed upon its rear end an arm 60 to which is'connected pivotally the upper extremity of a link 61 having its lower extremity joined pivotally with a lever 62, shown best in Fig. 6, Sheet 1, carrying a pin or roller (33 working in a groove 64 in the back side of the geanwheel 24, the said lever being pivoted at 65 to a stand or bracket 66 rising from the base or bed 1.
The result of the action of the machine as herein described is illustrated in Figs. 9, 10, and 11, in which the'label a is shown attached to the article b by two threads a? and a which are formed into stitches passing through the .said label and article and thus uniting the former to the latter. The number of stitches may vary, as deemedadvisable. It will be observed that the thread a is formed into loops a passing through the article and label from one side of these latter to the other thereof, and the thread a is extended through the said loops at the said other side, thus locking the loops so as to prevent their withdrawal. These stitches may be produced in.practice by adjusting the tensions of the respective threads of the two-thread lock-stitch sewing mechanism so that the thread a shall be under relatively heavy tension, and the thread a under rela tively slight tension. This adjustment of the tensions permits the loops a of the thread a to be extended through the article and label by the taut thread (t the said thread a remaining in straight condition at its side of the article and label. As thus combined, the threads hold the label to the article. One or more stitches are made in the article at each side of the label, as shown, so that strain upon the label may not start the stitches and disconnect the label. Loose ends of the thread are left projecting at both ends of the line of stitches as shown, partly for the same reason, but chiefly to serve as pull-ends which may be grasped for the purpose of pulling out the threads to enable the label to be detached; In practice I usually employ a thread a which, by reason of the nature of its material, or the treatment to which it has been subjected, or its greater size, is less liable to yield and bend than the thread a This favors the straight position of the thread a in the stitches, and
enables this result to be attained with less difference in the tension of the two threads. I have shown the thread a a little coarser than thread a A coarse thread is easier to grasp and pull upon than a fine one. For convenience in severing the two threads when the required line of stitches has been made, I provide a thread-cutting device upon the front end of the work-support, such device comprising the fixed blade 67 and the slotted guide 68 cooperating with the cutting edge thereof. At the conclusion of the operation of forming the line of stitches, the presse-rj having been raised, the article is pulled out from beneath the same, drawing out both the upper thread and the under thread from their sources of supply. The operator then causes the threads to make contact with the cutting edge of the blade 67, thereby severing them.
At 69 is shown a band-pulley for the re ception of the driving-band (not shown) to be employed in transmitting power for the purpose of actuating the machine. Intermediate the said pulley 69 and thegear-wheel 24 and main shaft 70, Figs. 2 and 3, of the sewing mechanism, from which the stitching devices and work-feeding devices are operated, I employ motion-transmitting devicesincluding a clutch and having combined therewith means for operating the said clutch to throw the same into action at the will of the operator. The parts just referred to are so con structed and combined that each time the clutch is thrown into action 1t remains in duce the required number of stitches and the,
other working parts have been actuated to perform the operations which are incident to attaching a label, severing the same from the strip a, and feeding the said strip forward in readiness for the attachment of the next label, and then the said clutch automatif cally ceases to act and the stitching devices and other working parts come to rest.
A convenient arrangement of motion-.
transmitting train and clutch-device is shown in the drawings, in which latter the shaft 71 of pulley 69 is furnished with a spur-pinion 72 meshing with the loose spurgear 73 upon the shaft 74 of gear 24. The gear 24 serves by engagement with the spurpinion 24 fixed upon the main shaft of the sewing machine to operate the latter. Spur-gear 73 is shown in dotted lines in Fig. 8. The clutch-device, see more particularly Fig. 8, comprises a toothedwheel which is fixed to the spur-gear 73 and like the latter is loose upon the shaft 74, an arm l 7 6 mounted upon the shaft 74 and made fast thereto by the clamping-screw 77, a clutchdog 78 pivoted to the arm 76, and a contracting spiral spring 79 having one end thereof in position to act against the tail of the clutch-dog 78. Engagement of the lever with the tail of the clutch-dog holds the working end of the latter out of engagement with the teeth of the toothed Wheel 7 5, and while this is the case the wheels 75 and- 73 remain unconnected with shaft 74, and when rotated by turning movement of the pulley 69 and its spur-pinion 72 simply turn loosely upon the shaft 74. When, however, the lever is moved by the operator so as to carry its working end away from the tail of the clutch-dog 78 and permit the spring 79 to move the working end of the clutch-dog into engagement with the teeth of the wheel 75, the wheels 75 and 73 become clutched to the shaft 74, thereby causing rotary movement to be transmitted to the wheel 24, with the result that the working parts of the machine are actuated. Having started the machine into action in the manner just described, the operator permits lever 80 to resume its norengaged with the working end of the clutchmal or tripping position, inasmuch as it is intended that at the conclusion of a rotation of the gear-wheel 24 the tail of the clutchdog 78 shall encounter the working end of the said lever 80 so that the clutch-dog 78 shall thereby be disengaged from the teeth of toothed wheel 75, thus unclutching the wheels 75' and 73 from shaft 74 and causing the machine to come to rest. In order to prevent overrunning of the machine when thus unclutched, the arm 76 is furnished with a projecting portion 84, and the lever 80 is furnished with a projection which passes into the path of the projection 84, and by engagement therewith positively stops the rotation of the said arm and of the shaft 7 4 and gear-wheel 24, etc. To prevent recoil of the parts the lever 80 is furnished with a shoulder 86, which, by engagement with the tail of the dog, serves to prevent recoil of arm 76 when the projection at 84 brings up solidly against the projection 85.
It will be perceived that the gear 24 through its actuation of the spur-pinion 24 serves to operate the stitch-forming devices, and by means of its cams and theqfin 52 serves to actuate the presservraising and lowering devices. the strip-feeding device,
and the cutter. Hence, when the said gear' is in motion the machine is operative; when the said gear stands at rest themachine is inoperative.
In order to gain suflicient time for commencing and terminating the operations in connection with the attachment of a label to an article I may, as shown in the draw ings, utilize intermittent gearing for the actuation of the stitch-forming devices. Thus, as shown best in Fig. 6,, a portion of the circumference of the gear-wheel 24 is without teeth, in order that while the toothless portion is moving past the spur-pinion 24 the latter may remain motionless. Thereby, the said pinion and the stitch-forming devices are permitted to remain at rest for a short time at the begiifii'ing of the rotationof the gear-wheel 24, and they also are permitted to come to rest a little before the completion of the rotation of the gear-wheel 24 and to remainat rest while such rotation terminates. To hold the pinion 24 locked so as to prevent the same from turning, and the stitch-forming devices from changing position, while the blank portion of the gearwheel 24 is presented tothe said pinion, I form the pinion with a flange 24 which is concave at one side as indicated in Fig. 5, and upon the gear 24 I provide a segmental convex locking surface 24 for engagement with the concavity of the flange 24. Vhile the convexity occupies the'concavity the pin ion 24 is held from turninggbutlas thereonvexity passes out of the concavity in the turning movement of the spur-gear 24, the
first tooth on thelatter succeeding the blank space comes into engagement with one oi the teeth of the spur-pinion 24", thereby setting the latter and the stitch-forming devices in motion.
