' The member 4 is formed with a'tra-nsverse recess 10 near its forward end to'lafl'ord a loop-taker cavity intermediate, the adjacent portions of the section. 5 and 6, thereby providing a post 11 at the forward or delivery extremity of the member 4 and rising from the bottom flange or platc lf'which affords; a support for the laterally swinging sect ons 5 and 6. v The throat-plate 12 is secured upon :the
post 11 at its forward end by means ofthe; screw 13, and upon the upper f'aceofthe rigid member at at its rearward end'bv means of the screws 14. The throat-plate is provided with the usual feed-dog apertures 15 and with the needle apertures 16 intermediate the same.
The outer portions of the swinging worksupport sections 5 and 6 are extended upwardly with their upper faces flush with those of the rigid portion of the member 4;, and are rovided with inwardly extending stud-shafts 17 secured in position by set.- screws 18 and having eccentric bearing portions 19 adjacent their heads upon which are journaled the spirallystoothed hnbportions 20 of the cup-shaped loop-tinting elements 21 each formed with the loop-seizing beak 22 and rovided with an axial thread-cavity in the mner face adjacent the other looptakin element, as represented more particularly in Fig. 6. Mounted within and longitudinally of each of the work-support sections 5 and G is a longitudinally extending loop-taker shaft 23 journaled at opposite ends in the bearing bushings 24 and having fixed thereon the spirally toothed pinion 25 meshing with the similar teeth of the looptaker hub 20.

I Secured within a suitably apertured' boss of the hub 39 is the rearwardly extendingpin 44 to which is fitted the transverse socket 45 of the strap -16 embracing the actuating eccentric 47 fixed upon the main-shaft 34;, The needle-arm 40 thus derives operative vibratory movements from the iecccntr c 47 and imparts to the needles 1 theirreciprocatory movements.
As represented 1n the drawings,
the looptakers are of well known construction. Each of theloop-ta'king elements-21 is provided in the lateral walls of its thread-cavity with an annular bearing shoulder to which is fitted, as represented in Fig. 6, the peripheral bearing rib48 ofa thread-case 49 containing a bobbin provided with amass of lower thread. At its inner end and at the upper side, spaced lugs 50 afiording segmental shoulders which are received by the roundedupplate or. hanger 51 which 18 provided with a finger 52 entering the space between said lugs for restraining the thread-case against rotation with its respective loop-taking element. plate 51 has at its lower extremity an angular block 53' which is forked to embrace the lug 54 projecting inwardly from the swinging work-support section to which each thread-case is formed with the.

The latch-plates are-provide in their inner faces and at their ad acent edges with recesses 59 to afford adjacent their opposite edges abrupt shoulders, and the post 11 is formed in its outer face with a recess 11 in register with the recesses 59'. The
"latch-plates 59 are provided with threaded apertures extending parallel with their outer faces in which are inserted adjusting screws 60 whose points are adapted to bear upon -verse slot. in which is pivotally mounted by means of the pin 61 a catch-lever 62 formed with a hooked nose 63 at its outer end and flattened ad acent its respective pivotal pin 61 to receive the free end of a flat spring 61 secured to a suitable seat in the outer edge of the section by means of a screw 65. The extremities of the sections 5 and 6 are provided with apertures 66 embracing portions of the catch-levers 62 and affording access thereto for pressure by the finger of the operator for retracting the catch-levers. When the swinging sections 5 are in operative position, their inner edges are held in contact with the adjacent edges of the catchplate 59 by engagement of the catch-levers 62 with the shoulders of the recesses 59, and either of them may be readily moved into inoperative position for access to its respective loop taker by retraction of the spring-pressed catch-lever 62.
The feedlog 07 is shown provided with the usual serrated feeding surfaces, and has a cylindrical shank 68 which is fitted within the tubular arm 69 of a rock-lever having the transversely apertured lug 70 and the rearwardly extending arm 71, said rocklever working in a central channel 1 arranged in the upper portion of the work-supporting member 4. The apertured lug 70 of the rock-lever is entered by and supported upon the transverse fulcrum-pin 72 mounted in the member -1 intermediate its ends, The rock-lever arm 71 carries at its rearward eX- tremi ty the screw-stud 73 which iS embraced by the apertured boss 74 at the lower end of a link 75 whose apertured opposite end embraces a stud-screw T0 tapped into the apertured boss of the needlelever hub 39. Rocking movements are thus imparted to the lever-arm 6 9 from the vibratory needle-lever for communicating to the feed-dog its rising and falling movements.
The shank 68 of the feed-dog is of tubular form terminating at the end adjacent the same in a socket in which is rigidly secured by means of the set-screw 77 one end of a thin resilient rod 7 8 whose oppositeend is secured by means of screws 79 in a socket formed in the head 80 of a rocking pin 81. The pin 81 is journaled within a transverse boss 82 formed at the end of a depending arm 83 of a rocking frame constituting the feed-rocker and formed with the sleeves 84 and 85 journaled upon the main-shaft 34: and connected together by means of the yoke 86 cridging the intermeshing gears 32 and 33.
The sleeve 85 of the rocking frame has secured upon its extremity the split hub 87 of an upwardly extending arm 88 carrying a stud 89 which is embraced by one apert-ured extremity of the link 90 whose forked and apertured opposite extremity is pivotally connected by means of the pin 91 with the upper end of a vibratory bar 92 adjustably secured near its lower end by means of the set-screw 93 within the apertured head 94 of a rocking fulcrum-pin 95 journaled within and transversely of the standard 1. The bar 92 is slidingly fitted near its upper end within the transverse boss 96 of a strap or sleeve 97 embracing the feed eccentric 98 which is mounted for lateral adjustment upon the slide-plate 99 of the collar 100 fixed upon the main-shaft, the adjustable feed eccentric being of well known form.
By. loosening the set-screw 93, the bar 92 may be adjusted vertically relatively to its fulcrum-pin 95, and the position of the connecting link 90 may be changed to correspondingly vary the point of connection between the arm 88 of the feed-rocker and the actuating eccentric 98. As will be observed,
the feed-rocker communicates its operative movements to the feed-dog through the arm 83 and rod 78 in the production of the workadvancing movements, the slight bending of the rod 7 8 intermediate its ends being permitted by reason of the clearance therefor afforded by the tubular form of the feed dog shank 68.
' he frame member 3,has upon the side thereof toward which the work-supporting member 4 extends the bearing lugs 101 in which is mounted the rock-shaft 102 to the end of which above the work-supporting member is secured by means of the set-screw 103 the hub 104 of the arm 105 overhanging the member 4 and provided at its extremity with the vertically apertured boss 106. \Vithin the boss 106 is secured by means of the set-screw 107 the presser-bar 108 having pivotally secured to its lower end by means of thepin 109 the rocking resser-foot 110 opposed to the feed-dog 67.
Surrounding the rock-shaft 102 is a coilspring 111 having one end secured to the adjacent bearing boss 101 and the other end secured to a collar 112 fastened upon the rock-shaft by means of the set-screw 113, this spring actingthrough the rock-shaft and arm 105 to force the presser-foot toward the throat-plate and feed-dog. The rock-shaft 102 has a depending arm 114 adapted for engagement by a lateral stud 115 carried by one arm 116 of an elbow-lever mounted upon the fulcrum-pin 11T journaled in the standard 1 and provided with the lateral arm 118 connected with the treadle-rod 119; By drawing down the rod 119 the shaft 102 may be rocked in opposition to itsspring 111 to lift thepresserfoot.
The frame member 3 is provided above its connection with the member 4 with a boss 120 upon which are secured the needlethread tension devices 121 with an inter-.
posed guide-plate 122 provided with suitably disposed guide-eyes for directing the threads to and from the tension, the-delivery eyes 123 being disposed above the space in termediate the component.- disks 121 of a rotary tension-wheel of well known construction fixed upon the adjacent extremity of the main-shaft 3%. In practice, the needlethreads are led through their respective tension devices and delivered to the take-up through the guide-eyes 123 and are thence led through the fixed guide-eye 125 to the needles.
The main-shaft 34 has secured thereon within the standard 1 the toothed pinion 126 meshing with the gear-wheel 127 which is mounted upon the short shaft 128 journaled within and transversely of the standard 1 and having the attached grooved belt-wheel 129 embraced by the driving belt 130. Power is thus communicated to the main-shaft by means housed entirely within the hollow standard and from which the operator is effectively shielded. The position of the mainshaft '31 substai'itially at right angles with the work-support, at the end of which the operator sits in operating the machine, makes it practicable to apply the handwheel 37 at the end of the main-shaft be- 'yond the frame standard where it is conveniently accessible to the operator.
In the installation of the machine, the base of the standard is preferably bolted upon the. work-table near the edge at which the operator sits. the frame member 3 being disposed parallel with and the member 1 directed away from such edge of the table. In the closing of the tubular portions of garments, the garments are carried over the table and beneath the junction of the frame members 3 and 4, the marginal portions to be united bein carried up over-the I work-supporting mem er and fed to the stitch-forming mechanism and away from the operator beyond the end of the member 4t where they are deposited without necessity of further handling on the part of the operator or disengagement from the machine, as in cylinder-bed machines heretofore in common use. This method of handling the work is permissible in accordance with the present improvement by reason of the special form of the frame which affords a clear space beneath and at the sides and ends of the work-supporting member for free and unobstructed passage of the body of the garment, and partly by reason of the construction and arrangement of the mechanism in which the work-engaging elements are sustained and operated by means following the angular contour of the frame and which present. the least possible obstruction of the view of the operator to the work at and beyond the stitching point. The operator is thus enabled to inspect not only the action of-the machine upon the work but to inspect the finished work as it isleaving the machine to insure its freedom from defect through any fault in the action of the machine.
From the foregoing description, it will be evident that a specially important feature of the present improvement is the form of theframe of which the work-supporting member is laterally offset and spaced from the standard relatively to which it extends transversely materially above the base of the latter. As shown and described herein, the work-supporting member and all the operative parts of the mechanism are sustained by the standard and extend from the same side thereof, thereby conforming with the shape of the frame in their construction and arrangement. The present construction therefore provides a frame in which the component parts are designed to provide an advan tageous means of suspension for the worksupporting member, no additional frame member being provided to sustain operative parts. which are all housed within or sustained by the frame as described.
