LABEL-SEWING- MACHINE.
Application filed April 17, 1922. Serial No. 553,433.
This invention relates to sewing machines,
. and is especially concerned with sewing machines of the character designed to sew labels on to undergarn'ients or other work.
The type of machine usually employed for this purpose at the present time includes a single needle guided in a hollowrectangular presser foot so that it sew around all four edges of the label. The present invention aims to devise a mechanism with which the labels can be secured to the work more neatly and expeditiously. The invention contemplates a machine which will secure a label or similar article to the work by sewing simultaneously across its opposite edges, and combines with such a mechanism means for properly presenting the label to the needles. It preferably includes also mechanism for turning under the edges or ends of the label prior to being sewed by the needles and means for automatically stopping the machine when the sewing operation has been completed.
The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

showing successive steps in the process of folding the ends of the label. The plane of cross-section of these views is substantially as indicated by the line 1212, Fig. 8.
Referring first to Fig. 2, L designates a label bearing the makers trade-mark, or other subject matter, and secured to a portion of the garment or other piece ofwork by seams or lines of stitches SS. This figure indicates the nature of the work which the present machine is intended to perform. 1
Themechanism embodying the present invention is shown in the drawings as applied to a Singer sewing machine, designated in general at 2, and provided with a needle bar 3 carrying a needle holder 4 in which are mounted two needles 55. --The machine also includes a presser foot 6 mounted on the lower end of a presser foot bar 7 All these parts are constructed, arranged and operated in the usual manner.
The label holding mechanism shown comprises a plate or holder 10, of approximately the length of a label, secured to the lower part 12 of a U-shaped frame having two side members 14 and 15. The plate 10 forms, in effect, a continuation of another plate 16 having its sides turned upwardly, as clearly shown in the drawings, to form a chute or hopper. The upper ends of the arms is and 15 are slotted to receive screws 18 and 19, respectively, by means of which they are secured to the opposite sides of a bracket 20 which is fastened to the presser bar sleeve 21 by a set screw 22. The arms 14 and 15 are pivoted on the opposite ends of a yoke 23 which is secured to the presser foot bar 7 by means of a set screw 24, screws 26 and 27, respectively, holding the two arms on the ends of the yoke. It will now be evident that when the presser foot bar is raised to lift the presser foot 6, the connections between this bar and the label holder will swing the label holder upward and forward i into approzrimately the relationship shown in Fig. 11.
In order to assist the operator in properly positioning a label in the holder, two stops 3030 are positioned near the forward edge of the holder. Each stop consists of a wire having a right angle bend therein, as clearly shown in the drawings, and both stops are secured in a small rock shaft 31 mounted in ears that project from the lower sides of members 32 and 33, respectively, which are secured to the opposite ends of a bar 34 guided in slots in 'the members lefand 15. The parts 32 and 33 are secured on the lower'en ds of rods 36 and 37, respectively,
carrying studs 38 and 39 at their upper ends which project through cam slots formed in disks 40 and 41, respectively, the cam groove in the part 40 being shown at 42, Fig. 8, and that in the other cam being identical with it. 7
These cam disks 40 and 41 are mounted to rotate on the opposite ends of the yoke 23 and they are connected together by a bar 43 so that they are compelled to rotate in unison. A pin M, Fig. 9, projecting inwardly from the-cam 40enters a slot formed in the lower part of a bracket l5 which is secured to the machine frame. Consequentwhen the presser foot bar is raised and lowered these connections produce a rotating movement of the cams 4:0 and 41, which movement is transmitted to the members 32, 33 and 34, reciprocating these members in a direction parallel to the side pieces 14L and 15 of the label holder frame. The rock shaft 31, on which the stops 30-30 are mounted, carries a forked piece 47 .which straddles a pin4-8 secured in the bar 15. The paths in the cams 40 andel are so designed that when the presser foot bar is elevated and the label holder is swung into its upper or label receiving position, the parts 32 and 33 are lifted and the stops 30-30 therefore are moved into their operative positions, as shown in Fig. 11, where they determine the position of the forward edge of the label in the holder. hen the presser foot is de pressed and the holder is swung into its lower position, where it presents the label in position to be engaged by the needles, the parts 33 and 34 are moved downwardly and this movement is transmitted to the stops 30-30, tipping them into their raised or inoperativepositions, as shown in Fig. 8.
When the label Lis placed in the holder its ends are guided by thenpturned sides of the plate 16. The plate 10, however, is not as wide as the plate 16, and'the end portions of the label, therefore, project beyond the opposite edges of this plate, as clearly shown, for instance, in Fig. 12. The forward movement of the label is limited at this time, as above stated, by the stops 3030.
lVhile the label is thus held in this position also has a depending finger, designated at 56 and 57, respectively, Fig. 12, and these lingers engage the opposite ends of the label after it has been placed on the plate 10 and thus serve to position it longitudinally.
lVhen the label is first placed in the holder the folders occupy substantially the relationship to theholder shown in Fig. 12. Immediately after the holder has begun to move back toward its label presenting position, the bar 34 is depressed through its connections with the cams 40 and 41, as above described, and this movement enables the folders to bend the ends of the label downwardly past the edges of the plate, as clearly shown in Fig. 13. The folders are next moved inwardly toward each'other enabling them to fold the ends of the label under the plate 10, as shown in Fig. 14: and for the purpose of producing this movement an additional cam operated mechanism is provided. This mechanism comprises two cams 58 and 59 adjustably secured to the outer faces of the respective cam disks 40 and 41. A screw 60, Fig. 8, secures the cam 58 in place and passes through a slot in the disk 40 so that the angular relationship between the two parts 410 and 58 may be adjusted. The parts 4-1 and 59 are similarly secured together; These cams are adapted to act, respectively, on the upper ends of levers 62 and 63 fulcrumed' on blocks 64 amino, respectively, which are secured to the rods 36 and 37 previously referred to. The lower ends of these levers are turned inwardly, as 7 are fastened to the respective blocks 52 and.
53. The screws that secure these disks in place are eccent-rically positioned in the disks so that the movements of the two blocks relatively to the plate 10 may be adjusted. This mechanism is timed to cause the folders to turn the ends of the label under, as shown in Fig. 14, prior to the completion of the downward movement of the holder.
The downward and inward movement of the holder carries the forward edge of the label under the points of the needles 5-5 so that as soon as themechine is started into operation the needles will descend, entering the label near it opposite ends, and as the machine continues to operate, the
- matically on to the loose pulley 71.
usual feeding mechanism will draw the label out of the holder, the stops 303O at this time being raised. Mechanism is provided for automatically stopping the machine after the needles have made a predetermined number of stitches and for causing the needles to make superposed stitches at the beginning and end of the line of stitches or seam made by each needle.
Referring to Figs. 1, 6 and 7, the fast and loose pulleys of the machine are shown at and 71, respectively, and the driving belt at 7 2. The position of the belt is controlled by a shipper fork 7 3 mounted on a bracket 74 which is fulcrumed at 75 and is normally held with the belt on the loose pulley 71 by means of a spring 76 included in the connections between the bracket 74 and the treadle 77. WVhen this treadle is depressed the bracket 74 is rocked in a counter-clockwise direction, Fig. 1, thus throwing the belt 7 2 on to the fast pulley 70 and starting the main shaft 78 ofthe machine. Another shaft 80 is driven through a bevel gear connection 81 with the shaft 78 and carries a worm 82 driving a worm wheel 83 fast on a horizontal shaft 84 which is mounted at the rear of the machine. This shaft carries a cam 85 which operates a brake lever 86, and it also carries a throw-out cam 87 adapted to actuate, at certain times, a dog 88 which is pivoted on a screw 113, Fig. 7. After the machine has been started into operation a spring 89, acting through the dog 88, holds the shipper fork 73 in its running position; but when the machine has made a predetermined number of revolutions, and therefore has produced a given number of stitches, one of the projections of the cam 87 engages the dog 88 and swings it away from the fork 73, thus allow ing the spring 76 to shift the belt 72 auto- At the same time that this happens, the cam 85 operates the lever 86 to apply the brake to the fast pulley 7 0 and thus slow up the machine. Also, while these operations are taking place a pin 90, Fig. 7, projecting from the pulley 70, is engaging a curved arm 91 which projects laterally from a head formed on the upper end of a post 92 which is mounted in the bracket 74 and is held in its raised position by a spring 93. The pin 90 thus depresses the arm 91 against the tension of thespring 92 and finally comes to rest in a socket 94 in the head thus stopping the machine in a predetermined position with the needles 55 elevated. It will be understood that when the treadle 77 is depresed again to start the machme, the con nections with the bracket 74 tip it far enough to disengage the socket 94 from the pin 90 so that these parts then will not interfere with the starting of the machine.
The feeding movement of the work is effected in the usual manner through connections with a feed lever 96, Fig. 1, but this feeding movement is, according to the present invention, controlled in a novel manner. The lever 96 forms essentially an eccentric strap running on a tubular projection or sleeve 97, Fig. 4, extending from a plate 98 secured to the face of a disk 99 mounted fast on the shaft 78. The plate 98 is'pivoted on a screw 100, and its range of movement is limited by another screw 101 projecting through a slot formed in the opposite edge of the plate. A spring 102, mounted in one side of the plate 98, presses a block 103 against the surface of the shaft 7 8 and tends to swing the plate 98 about the pivot 100, this movement however, being limited by an adjusting screw 103 which is mounted in the opposite side of the plate 98 and has an end projecting through a hole formed in the shaft 78 and bearing against the tip of a plunger 104 located axially in the shaft 78. This plunger has a reduced tip 105, Fig. 5, and a slightly larger portion 106 immediately behind the tip 105. When the adjusting screw 103 engages the tip 105, the plate 98 is then held by the spring 102 and pin 103 with the sleeve 97 in a concentric relationhip to the shaft 78. Consequently, no oscillating movement will be imparted to the feed lever 96 at this time. hen, however, the plunger is moved inwardly to bring the part 106 thereof in engagement with the screw 103, the plate 98 will be tipped to the right, Fig. 4, thus moving the sleeve 97 into an eccentric position. The sleeve now imparts an oscillating movement to the lever 96 which,
in turn, operates the usual work feeding mechanism.
The inward and outward movement of the plunger 104 is produced by a cam 108, Figs. 6 and 7, secured fast on the shaft 84. This cam has a cam path 109 to receive a roll 110, mounted on the end of a lever 112,which is fulcrumed on a screw 113 and carries another roll 114 at its opposite end running between the flanges of a grooved collar 115 secured on the end of the plunger 104. The cam path 109 is so designed that when the machine starts into operation the needles 5-5 make two stitches without feeding. Their normal feeding movement is then begun and continued until a predetermined number of stitches have been made through each end of the label. Then, as the machine is about to stop automatically, the needles make two more stitches without feeding. These superposed stitches at the opposite ends of each seam tie the thread sufficiently to prevent it from unravelling.
It will now be understood that it is merely necessary for the operatorto place a label in the holder 16, this'operation being performed when the machine is stopped and the presser foot raised, and then to depress the presser :footeithcr icy-moving the presser foot lever 1L6, Fig. 8, or by depressing a treadle which is connected with the presser foot in a manner usual in machines of this type. This results in automatically turning under the ends of the label and presenting the label in proper position for engagement by the-needles. The operator next depresses the 'treadle 77 and immediately releases it :again, this operation serving to start the machine into action, whereupon it automatically causes the needles to sew across the opposite ends or edges of the label and stop automatically. The operator then removes the work, cuts the threads, replaces another piece of work, introduces another label, and repeats the operations just described.
The machine performs the label sewing operation very neatly and more rapidly than the machines hereto-fore used for this purpose. V
\Vhile I have herein shown and described the best embodiment of the invention which I have so far devised, it will readily be appreciated that the invention is susceptible :of lernb'odiment'in many forms differing in details of construction from the arrangement shown. I do not wish, therefore, to be limited to the particular construction shown. It will also be appreciated that while I have described the machine as adapted particularly for sewing on labels, since this is an important commercial field for the machine, it is, nevertheless, adapted to other uses where two parallel lines of stitches-are to be made and the machine stopped automatically.
Having thus described my invention, what I desire to claim as new is: r
-1. In a sewing machine having two needles spaced apart, the combination of means for presenting'alabelin position to have its opposite edges sewed to the work. I
