W/T/VESSES transverse section through the label-clamp adjacent the severing knife.

The machine is constructed with the usual frame comprising the bed-plate 1 and overhanging bracket-arm 2 in which latter is journaled the main-shaft 3 operatively connected at its forward end with the rectilinearly reciprocating needle-bar 4 carrying the needle 5 cooperating with which in the production of stitches is the shuttle 6 mounted in the race 7 beneath the bed-plate and actuated by means of the rock-shaft 8 operatively connected with the. rearward portion of the main-shaft.

The longitudinally reciprocating and laterally swinging work-blamp carrying slide-bar 9 has depending from its rearward end a slide-block 10 moving in the usual guide-slot of the bed-plate 1 and pivIOtally secured to said slide-bar by means of a fulcrum-stud 11 (indicated partially in Fig. 3). The slide-bar 9 receives its longitudinal movements through 'a rigid post 12 having adjustably secured thereon by means' of the set-screw 13 a contact block 14 fitted within the dependingslotted arm 15 of a rock-lever having a fixed fulcrum at 16 and provided with an upwardly extending arm 17 carrying a roller-stud 18 entering the cam-groove 19 in the forward face of the rotary camwheel 20 mounted upon the fixed fulcrumstud 21 and having a worm-wheel 22 meshing with the worm 23 upon the main-shaft 3. The rearward face of the cam-wheel is formed with a cam-groove 24 entered by the stud 25 carried-by the upper arm 26 of a rock-lever having a fixed fulcrum at 27 and having a'lower arm 28 adjustably connected by means of the sectional link 29 with a rearwardly extending arm 30 of an elbow-lever whose forwardly extending arm 31 has a transverse link connection 32 with the usual stud depending from the forward portion of the slide-bar 9, whereby lateral swinging -movements are imparted to the slide-bar.

The cam- grooves 19 and 24 are suitably shaped for. cofiperation in imparting to the forward end of the slide-bar 9 ste -by-step feeding movementsin arectangu ar path,

the adjustments of the connecting trains ofmechanism serving to determine the lengths of travel of the work-clamp"longitudinally and laterally of the bed-plate.

Secured upon the forward end of the slide-bar 9,by means of the bolt 33an'd steady pins 34 is the lower work-clamp plate 35 having its upper face roughened orserrated to form the lower java of the primary workclamp, and overlying the same is the serrated lower face of the upper primary clamp member 36 in the form of a hollow rectangle, such member having (as indicated in Fig. 3) a rearwardly o fi'set lug grooved upon its under side to receive, and secured by means of a screw 38 upon, the forwardly projecting portion 39 of the slide-bar 40 which is journaled in a suitable guideway in the head 41 of the goose-neck frame 42 of the attachment which is rigidly secured by means of fastening screws 43 upon the slidebar 9. The rectangular needle-aperture of the clamp member 36 affords a label cavity in which is introduced a label-receiving shell having side-walls 44 fitted to those of the label cavityon three sides and having at the bottom an inwardly extendingnarrow lip 45 of rectangular formto afford a label-supporting seat, such shell having along its upper edges the outwardl extending flanges 46 with screw-apertures 4 entered by screws 48 for securing them upon the top of the member 36. Loosely fitted to the side walls of the label cavity is the rectangular labelclamping foot 49 whose lower serrated edges afford the upper clamping jaws for the margin 'of the label, such foot being provided with a rearwardly extending lug 50 ribbed upon its under side and provided with an aperture 51 to receive the fastening screw 52 their guideways.v Each of the slide-bars 40 and 54 is notched in its upper end to receive the forward end of one of the spring wires 57 whose down-turned ends 58 enter suitable apertures in a lug 59 upon the attachment frame42, while the intermediate portions of such springs are pressed downwardly by engagement with the points of adjusting screws 60 extending through thelug 61 upon the attachment frame and se-' cured against turning by means of the jamnuts' 62.

The upper work-clamp member 36 has a forwardly and upwardly extending portion 36* formed with a segmental slideway, of rectangular 'cros's-section'but open at the top and provided with overhanging plates 63' secured thereon upon opposite sides of such slideway by means of fastening screws. 64 and having depending guard-lips 65 spaced inwardly from the walls of said slideway.- Within said slideway is fitted a segmental channel-shaped member .66 having a central rib 67, and affording a guidechannel to receive the tape to be fed into the label cavity in register therewith and formthe bottom a-sharp edge of arched form ing a continuation thereof. The end of the member 66 is cut ofi' transversely to form at serving as a ledger blade in conjunction with a movable knife-.bladein severing short lengths from the tape to form the labels to be attached to the body fabric. Upon the outer end portion of the tape-guiding member 66 is adjustably secured by means of screws 68 a plate 69 provided with a hook 70 to which is attached one end of a spring 71 whose opposite epd embraces a hook 72 upon a plate 73 adjustably secured by means of screws74: upon the adjacent end of the clamp member extension 36*, whereby the tape-guiding member 66 is normally pressed toward the label cavity. Upon the end of the label clamping foot 49 is secured by means of screws 7 5 the transverse knifeblade 76 whose sharpened lower edge cooperates with the ledger-blade 66 at the adjacent end of the tape-guiding member 66 in severing the tape as said foot is lowered into operative position. i

Tapped into the forward face of the slidebar 40 concentrically with the guiding channel of the tape-guiding member 66 is a shouldered stud-screw 77 upon which is fulcrumed the hub 78 of the swinging arm or lever 79 which is formed with a radial socket 80 having fitted therein the head 81 of a plunger with reduced stem 82 passing 1 through the inner end of the socket and terminating in the head 83. A spring 8% surrounding the stem 82 is interposed between the plunger-head 81 and the end of the socket 80 for forcing the plunger-head toward the guide-member 66, and the plunger-head' is provided with a bifurcated tapefeeding foot or claw 85 serrated upon its operative edges. The plunger head is provided with a lateral wing 86 passing through a slot 87 in the wall of the socket 80 with its outer edge adapted for engagement by the hooked member 88. of a pawllever 89 pivotally mounted upon a screw-stud 90 upon the swinging arm 7 9. The pawl-lever 89 is provided with a laterall extending lug 91 between which and the bottom of a socket formed in the arm 79 is interposed a spring 92 for normally pressin the nose of the hook 88 toward the wing 86 of the plunger, and the lever 89 is provided with a rearwardly extending arm 93 ada ted for engagement with the cam-plate 94 disposed at the adjacent side of the extension 36 of the clamp member 36 bv means of a fastening.

screw '95 extending through the angularly disposed foot-piece 96 of said cam-plate. The plunger-head is also provided upon its rearward; side with a stud 97 passing through a slot 98 in the socket and carrying a roller 99 adapted in the advance position of the carrving arm 79 to move up the camshaped upper edge 100 of the cam-block 101 adjustably secured to the side of the clamp member extension 36 by means of a screw 102 entering a slot 103 in such block; and said roller is also adapted to ride down the cam-shapedfedge 104: of the cam-block 105 whichis also adjustably secured upon the side of the clamp member extension 36 by means of screws 106 entering suitable slots in said block.

Secured to the lu 37 of the clam member 36 by means of the fastening screw 107 is a bracket-piece 108 carrying a segmental guide-rod 109 overlying but spaced slightly above the rib 66 ofthe tape-guiding channel member 66, tape-smoothing wings 110 and 111 being providedat the opposite extremities of the rod 109 and conforming in their lower or operative faces with but spaced above the bottom of the tape channel so as to insure the entrance and delivery of the tape in arched form to and from the tapeguiding channel. The rod 109 is shown formed with upturned end 109 to facilitate the introduction of the tape in the space between the same and the rib 66 of the chan nel. The object of arching the bottom of the channel is to arch the label so as to stiflen it for feeding and also to provide a corresponding form for the edge "of the ledgerblade at the entrance to the label cavity so as to insure a draw out between the ledgerblade and the straight operative edge of the movable knife-blade 7 6.

The carrying arm 79 forthe tape-feeding foot has extending forwardly from its hub an arm 112 provided with a slot 113 in radial relation with the fulcrum-stud 77, which slot is entered by a roller 114 carried by a stud 115 tapped into a lateral extension 55* of the face-plate 55 and secured therein by a jam-nut 116. As will be observed, the lift ing of the slide-bar d0 carries the fulcrumstud 77 upwardly, and the engagement of the slotted member 112 of the feed-arm 79 causes the advance of the latter toward the label cavity, while the lowering of the slidebar produces a reciprocal motion of the arm 79.

As shown in Figs. 1 and 2, the machine is provided with clamp-lifting means comprising the reciprocating bar 117 1ournaled in the head of the bracket-arm and provided with a fixed collar 118 between which and the upper bearing member is interposed the spring 119 for normally pressing the bar downwardly. The reduced lower end of this lifting bar has fixed thereon by means ofthe screw 120 the boss 121 of a rigid angular arm 122 whose operative portion extends parallel with and adjacent the face-plate 55 of the attachment frame and beneath forwardly extending studs 123 and 124 tapped into lateral ears 125 and 126 of the clampoperating slide-rods 40 and 5%, such studs passing through slots '127 in the face-plate 55. The lifting bar 117 has fixed upon its upper end portion a collar 128 beneath which extends the forked forward end 129 of the rock-lever 130 fulcrumed at 131 upon the bearing bracket 132 and having inthe extremity of its rearwardly extending arm the aperture 133 'for attachment of the treadle rod or other usual connection to actuating means beneath the machine base.

lln the normal positions of the parts, the pressure members 36 and 49 are maintained in their lower or operative positions under the action of the springs 57, the tape-feeder carrying arm 7 9 being in its upper or retracted'position, in which the lateral arm 93 0f the pawl-lever 89 is in engagement with thecam-plate 94 so as to disengage the hook 88 of such lever from the wing 86 of the plunger 81, while the roller-stud 97 of said plunger rests upon the upper operative edge of the cam-block 105 for maintaining the tape-feeding foot 85 lifted above the bottom of the tape-channel in opposition to the spring 84.

Preparatory to the operation of the machine, the end of the tape, which may be wound upon a spool supported upon the head of the brackevarm in a well-known manner, is introduced into the tape-guiding channel beneath the guide-rod 109 to the forward end of the member 66 and abutted against the flat face of the lmife-blade 76. The actuation of the rock-lever 130' to raise the lifting arm 122 serves to engage successively the pins 124 and 123 of the slide-bars 54- and 40 so as to first partially lift the label-clamping member 49 to admit the tape and then impart the requisite lifting movement to the work-clamp member 36. As the slide-bar 40 rises, it carries upwardly the fulcrum-stud 77 and the arm 79 advances toward the label cavity, which causes the roller-stud 97 to move down the inclined edge'of the cam-block 105 so as'to engage and advance the label strip or tape until the cam-roller rides up the inclined operative edge 100 of the cam-block 101, when the feeding foot-85 becomes disengaged from the surface of the tapeejust as its forward extremity reaches the end wall of the label cavity, As the plunger 81 is forced upwardly, the nose of the pawl 88 snaps beneath the guide-wing 86 and thus locks the feeding foot in raised or retracted position. The release of the rock-lever 130 now permits the lifting arm 122 to descend so as to first seat the work-clamp member 36 firmly upon the body fabric previously introduced between the same and-the clamp-plate 35, after which the label clamp member 49 descends upon the portion of the tape lying within the latter, and in so doing carries the knife-blade 76 downwardly in contact with the ledger-blade 66 whereby the section of tape within the label cavity is severed from the body of the tape and securely clamped around its edges upon the seat therefor afforded above the body fabric by the inwardly extending lips 45 of the hold.-

ing member 44. The efiective coiiperative relation between the blades 76 and 66 is insured by the action of the spring 71 which forces the ledger-blade yieldingly in contact with the reciprocating blade. In the retrograde movement of the feeder-carrying arm 79 under the descending movement of the slide-bar 40, the engagement of the pawllever 89 with the guide-wing 86 of the plunger 81 maintains the feeding foot 85 lifted above the tape, so that the return of this member to initial position has no effect upon the tape. As the swinging arm nears its initial position, the member 93 of the pawl.

lever 89 again engages the cam-plate 94 whereby the nose 88 of the pawl-lever is disengaged from the wing 86, but the descent of the feeding foot into operative relation with the work is prevented by the engagement of the roller-stud 97 with the upper portion of the cam-block 105. 3

While the embodiment-of the present improvement shown and described herein is deemed preferable, it is to be understood that the details of construction and arrangement of its various parts may be modified to a considerable degree without departure from the scope of the present invention.

llt is evident that the tape-smoothing wings 110 and 111 may, if desired, be made in a continuous plate with suitable slots to receive the bifurcated feeding foot 85, in lieu of the connecting rod 109, and may be secured in position within the tape-guiding member 66 by any suitable or convenient means.
