.To all whom it mai/ concern,.-Y

Be it known that I, Louis SoHULTz, of New York, in the State of New York, have invented a certain new and useful Improvement in take-up mechanism.`

Quilting-Machinesof which the following' is a specification. l

I will describe in detail a'quilting-machine embodying my improvement, andthen point out the novel features in-claims.

Fig. 12 is a front. elevation of a quilting-machine, embodying my improvement, on an enlarged scale, certain portions being broken away to save space ,and certain other portions being removed to disclose parts which would otherwise be concealed.` Fig. 13 is afview, partly in section, of certain portions. of the Fig. 14 is a View of Y similar parts shown in a diferentposition to secured together by cross-bars A2, here shown as three in number.

B designates a carriage upon. which the work to be quilted is supported and carried along. This carriage rests upon rollers b, arranged at the portions A A of' the frame and journaled therein, ashere shown, upon axles machine.

b. The carriage may be moved to and fro or from side to side of the machine upon these rollers. This motion is for imparting alati eral or sidewise movement tov the goods, Jfor reasons subsequently to bc explained. The goods to be quilted are rolled upon a `delivery-roller, B', whose journals rest in suitable bearings in downwardlysextending arm-like portions B'l of, the carriage at the front of the From this roller the goods pass between tension-rollers B3 'B4 B5, the rollers B4 B5 being journaled in suitable bearings in the portions B2 of the carriage. The roller B3 is arranged intermediate of the rollers B4 B5, or, in otherrwords, so that it may bear against both said rollers. Itis journaled in levers B, arranged one upon the outside of each of the portions Bl of the carriage. These levers are loosely hung near one of their ends, as here shown upon screws B7, and have their lower B8, extending between the portions A A of the frame and rigidly secured thereto at both ends. From the work-plate the goods pass between feed-rollers B9 B10, and from thence to a take-up roller, B. The feed-roller B9 is journaled in bracket-like portions B12 of the carriage B, which, as here shfr'vn, are integral with the portions B2 thereoi, and extend fore and aft of the machine-and over the work plate BB. The roller Bgis geared to the roller B19 by gear-wheels b3 barranged one upon the end of each of the rollers outside the portion Buof the carriage and adjacent to the portion A of the frame. By this means motion imparted to theroller B9 will be transmitted to the roller B1". The roller B10 is journalcd in levers B13, fulcrumed one upon each of the portions Bl2 of the carriage. Adjusting devicesB14 (here shown as screws Working in tapped holes `in lugs b5 upon the bracket-like portions B12 of "the carriage) bear against the free ends of said IOO levers. By adjusting these screws the rollers B10 may be brought nearer to or farther from the roller B0, and the pressure upon the goods increased or decreased. The take-up roller Bu is journaled in suitable bearings in the outer extremities of the bracket-like portions Bl2 of the carriage, and has motion imparted to it by means of a belt, B15, passing over a pulley, B10, on said roller, and another pulley, B, on the roller B0, so that the roller B0 and the take-up roller rotate in unison. In this machine the goods have a lateral motion, or from side to side of the machine,in which motion there occurs a dwell. They have also a forward motion in which there occurs a dwell. These motions are practically intermittent. The lateral motion is imparted to the goods by the carriage B, but they receive the forward motion in the following manner: The feedroller B0 extends outside the portion A of the frame through a suitable aperture therein. Its outer portion or neck, b, extends loosely through a hub, b0,forming portion of a ratchetwheel, B10. This hub extends upon both sides of the ratchet-wheel. The side thereof near the portion A of the frame is journaled in bearings b7 upon an extension of said portion of the frame, and is provided with a flange, bg, outside said bearing. This flange prevents movement of the ratchet-wheel lengthwise of the neck of the roller in one direction. The portion of said hub on the opposite side of the ratchet-wheel has loosely hung upon it a pawl-carrier, Bm. Beyond the pawlcarrier a ring or collar, b0, surrounds the hub. A screw, 1,10, working in tapped holes in the collar b and in the hub, secures the collar to the hub. This collar prevents the pawl-carrier B10 from moving off from the hub. In the neck b of the roller B0 is a. longitudinal slot, into which extends loosely the inner end of the screw bm. It will therefore be seen that rotary motion imparted to the ratchet-wheel will be communicated to the roller B0,and that the said roller may move lengthwise in the ratchet-wheel and in its bearings, or, in other words, may follow the side-to-side movements of the carriage B, in which it is journaled.

The pawl-carrier B19 bears upon it near its free end a pawl, B20, adapted to engage with the ratchet-wheel. The pawlcarrier rests normally upon a horizontally-arranged eamwheel, B21, rigidly mounted upon a vertical shaft, C, journaled in bearings c, extending from the portion A of the frame and receiving motion from a bevel gea1wheel,G,mount ed upon the main shaft E of the machine,and meshing into another bevel gear-wheel, C2, on the shaft C. The shape of the cam-wheel Bll is such that at each revolution it imparts an npand-down rocking motion to the pawl-earrier B, which causes the pawl B20 to rotate the ratchet-wheel a distance equal to the length of one tooth on said wheel. A spring, Z110, secured at one end to the pawl-carrier B19 and 4at the other end to an extension on the portion A of the frame,serves to keep said pawlcarrier in contact with the cam-wheel B01. A locking-pawl, B22, hung loosely upon the portion A of the frame, bears upon the ratchetwheel and operates to prevent back motion of the ratchet-wheel. Owing to the positions which the pawls B20 and B0'l occupy they are adapted to operate by gravity, but springs may be used to facilitate their engagement with the ratchet-wheel.

It will be seen that each time the ratchet wheel is rotated the distance of one tooth a proportionate rotary motion is imparted to the roller B0, whereby the goods are fed forward intermittently.

In the example of my improvement shown the machine is designed for sewing a pattern composed of sinuous or zigzag lines meeting, approaching,or crossing each other at different points upon the goods. It is for this reason that a sidewise as well as a forward movement is imparted to the goods when being sewed, for if with the forward feed of the goods is also combined a motion from side to side, each of the needles will sew a zigzag or sinuous line, and by certain arrangements of the needles the lines of the zigzag may be made to meet at their corners or cross each other, whereby a diamond or analogous shaped pattern will be produced. The goods being carried bythe carriage B, if sidewise movement be imparted to the latter, lines of stitching in the direction of the width of the goods must necessarily be produced. The movement of the carriage is intermittentand simultaneous with the forward feed of the goods,both the forward feed and the sidewise movement occurring when the needles are raised out of the goods. As these two movements occur together, they result in producing lines of stitching which are angular or sinuous. Intermittent sidewise movement is imparted to the goods by the following mechanism:

lD designates an arm rigid upon and forming portion of the carriage B. It extends for a distance beyond the portion A of the frame and at approximate right angles thereto. Near its outer end such arm is provided with a longitudinal slot, d. Upon one of the sides of the arm D two anti-friction rollers, d, are mounted upon pins or studs. Between these rollers is arranged a cam, D', rigidly mounted upon a horizontal shaft, D2, extending at approximate right angles to the arm D and through the slot d therein. Thisshaft is journaled in bearings upon projecting portions A0 A* of the frame.

Near one end the shaft has mounted upon it a bevel gear-wheel, D0, which receives motion from another bevel gear wheel, D, mounted upon a short shaft, D5, extending at approximate right angles to the shaft D2 and journaled in suitable bearings in the portion A4 of the frame. Mounted upon the shaft D0 is a worm-wheel, D0, receiving motion from a worm, D', upon an upright shaft, D, jour- :naled in suitable bearings upon the --main frame. An elliptical gear-wheel, D, is rigidly mounted upon the shaft D8 near its upper end.

`Motion is imparted to this elliptical gearwheel by another elliptical gear-wheel, Dm, mounted rigidly upon a short upright shaft, D, journaled in suitable bearings on the main frame. Motion is imparted to the shaft D1l by means of a bevel gear-wheel, D, mounted upon the main shalt E- and meshing.

lwith another bevelgear-wheel, D13, upon the upper end of the shaft Du. The arrangement ofthe elliptical gear-wheels D9 D10 upon their respective shafts is such that avariable rotary motion will be imparted to the shaft D, which through the intermediate mechanism described will be transmitted to the cam vD' upon the shaft D2. The cam D is heart-shaped. lt will therefore during one half of a rotation act against one of the rollers d', and during the other half rotation upon the other roller.

It consequently operates to move the carriage B to and fro, and because the rotary motion of the cam D is made to consist of alternate accelerations and dwells, or, in other words, is practically intermittent, owing to the use ofthe elliptical gear-wheels D9 D10, it imparts an intermittent movement tothe carriage.

Having thus described the manner in which the goods are fed and moved along, Iwill now describe the needle-operating mechanism.

I designates the needle-bar, here shown as provided with two rows of needles, the needles of one row being arranged intermediate ofthe needles ofthe other row. Such arrangement of the needles is, however, not essential. The needle-bar extends from side to side of the machine and has vertical motion imparted lto it by means of links I', pivotally connected near one of their ends to the outer ends of the needle-bar beyond the portions A A of the frame. These links are also pivtally connected to rocking levers I2, loosely hung near one of their ends upon pins or studs z', extending from the portions A A of the frame. In these levers are longitudinal slots i. Slideblocks I3 are arranged and adapted to slide to and fro in the slots i. These slide-blocks are mounted upon crank-pins i2, extending from the sides of disks It, which are rigidly mounted upon short shafts l5, near one of the ends of the latter.

The shafts I5 arejournaled in side portions,

i3, of hollow cylindrical shells or cases l, near A the peripheriesof the latter. The shells or cases I arev rigidly mounted upon a shaft, 17,

extending from side to side of the machine. Rotary motion is imparted to the shells or cases I6 by means of gear-wheels ls, mounted upon ings for said shaft. These sleeves yare rigidly secured to the portions A A of the frame, as

V11 mesh with gear-wheels l, rigidly mounted upon the shafts l5. As the shells or cases I are rotated they not only carry with them in their rotation the shafts I5, but an independent rotary motion is imparted to the shafts Rand consequently the disks 1*, by means of the gear-wheels 1w In. The combined movement is such that the crank-pins i2 will travel in elliptical paths about the axis of the shells or cases I6, and will consequently vary the upand-downmotion transmitted to the levers l2 in such manner that a dwell will occur in the movement of the needle-bar at the time when the' needle-bar is in its lowermost position, or when the needles are down. This dwell is`for the purpose of affording time for the shuttles to pass through the loops ot' 9o the needles will be Withdrawn from and returned to the goods quickly.- Guide-rods I, arranged vertically upon and aiiixed to the needle-bar, act to prevent lengthwise movement of the needle-bar.

In the example of my improvement shown in Fig. 9 I have shown a different means for imparting vertical movement to the needlebar from that previously described. Such means consist in a link, L, pivotally connected near one end with the needle-bar, and having a pivotal connection near its other end with one end of a link, L', which latter link is loosely connected to a crank-pin, l, on the` bevel gear-wheel D. About midway in the length of the link L the same has pivotally connected to it 011e end of alink, L2, the other end of which'is loosely connected to a crankpin on the gear-wheel I9, which in this example of my improvement is arranged inasomewhat lower plane than the gear-wheel I8. As

.the gear-wheels rotate the motion transmitted a dwell will occur in the nievement ofthe needle-bar when the sameis at thelowestpoint inits downward movement.

J designates a bar extending from side to side of the machine by which the shuttle-drivers, as J', are actuated to move shuttles, as J2, through the loops of the needlethreads. The shuttles Jtslide in shuttle-races, as J5, mounted upon a transversely-extending bar, J6. I have shown but one of the shuttles and shuttledrivers, but it is to be understood thattheir numbers will correspond with the number of needles employed.y This Ashuttle-driver lJ has its rearend aliixed to the bar J by means of a pin or screw. The shuttle-drivers will there-A IIO fore follow the bar J in its movements toward and from the front ofthe machine. The driver slides in its shuttlerace J3 lengthwise of the lattei` and carries with it the shuttle, the shut tle being retained thereon by means of a curved finger, j, andaJ projectiomj, upon the upper side of the shuttle-carrier, or in any well-known or convenient manner.

Backwardand forward-motion is imparted to the bar J by means of links jf, pivotally connected near one of their ends to said bar. Near the other ofthe ends of these links they are pivotally connected to one of the ends of links j and one of the ends of links j* by means of pins or pivots extending through suitable ,holes in all the links. The links j are connected near their other ends with crank-pins j on crank-disks J*, rigidly mounted one upon the lower end of the shaft C and the other npon the lower end of the shaft D, The other ends of the links j have pivotal connections with the frame of the machine. I have shown an edge view of one part of this mechanism in Fig. 2, and another edge View of another part in dotted outline in Fig. 3. Fig. 4 is a plan or top view of the part shown in Fig. 2. I have not shown a plan of that part shownin Fig. 3, but it is in all respectslike that shown in Fig. l.

It will be readily seen that by properly proportioning the linksj'", j, and j* relatively to each other` the movement of the bar J maybe such that a dwell will occur at a predetermined point. This dwell in myimprovement occurs when the needles. are moving upwardly or when the bar J is in its most forward position, and is for the purpose of affording opportunity for tightening the loops of needle threads about the shuttle-threznls. \Vhen the loops have been so tightened, the shuttles are withdrawn and again returned quickly. Rods J5 upon the bar J, extending laterally therefrom and through gnidesj5 on the frame of the machine, operate to prevent lengthwise movement of the bar J.

A very important feature of my invention consists of the take-up for taking up the slack of the needle-thread when the needles are `moving upwardly, which I will now describe. l) designates a rocking-bar arranged somewhat above and approximately parallel with the needle-nar. As shown, this bar consists of a fiat piece or strip of metal provided upon one side with a longitudinal rib, F'. Near its ends the bar is connected to arms c of levers p2, fnlernmed upon pins or studs rigid in the frame of the machine. The connection between the bar l? and the levers p is preferably adjustable vertically. A convenient means of effecting such an adjustment is by means of screws f, extending through vertical slots f in the bar P,near the ends of the latter, and working in tapped holes in the levers F2, as shown. By this means the bar P may be adjusted to a desired height. The levers P2 rock upon their fulcra. They are caused so to rock by means of rods f, having a pivotal connection near one of their ends with upwardly-projeeting arm-like portions f upon the needle-bar. These rods extend into sockets f", formed upon arms f5 of the levers I, and may slide freely to and fro in such sockets. The needle-bar in its up and down movements of course carries with it the rods fl, which are thereby caused to slide to and fro in the sockets f, and therefore to rock the levers upon their fulcra. The levers, by being so rocked, cause the bar I not only t0 receive a bodily vertical movement, but also cause it to tilt or rock in such manner that when the needles have reached the lowest point in their downward movement the bar.

which has followed themin their downward movement, will have assumed an approximately horizontal position,and the thread will have an abundance of slack to form the loop. On the other hand,when the needles have reached the highest point in their lmovements the bar I, which has also followed them in their upward movements taking up the slack, will have been tilted into an approximately vertical plane, thereby tightening the loop. This arrangement is very advantageous, because all the threads are tightened at once and uniformly. The rib l? on the bar P assists in causing the threads to be drawn tightly at the end of .the stitch, because it elevates the thread above the surface of the bar I), and in so doing draws the thread. y

Spools or reels (of which I have shown but one) supply needle-thread to the needles. This spool is mounted upon a pin or stud, s, extending from a cross-bar, S, arranged between the portions A A of the frame and rigidly affixed thereto. The thread after leaving the spool passes through an eye, s', in an arm, s2, extending downwardly and outwardly from the bar S. From thence it passes through a clip, sa, upon the arm s2, thence through a notch, s4, in the under side of'a bar, S', extending between the side portions oll the frame and rigidly affixed thereto. The thread is retained insuch notch by means of a slight spring, s, secured at one end to the bar S and extending across the notch s. The thread may be slipped under this spring and into the notch. From the notch s the thread passes into a notch, s, on the bar P, wherein it is retained by a spring, S7, similar to the spring From thence it passes to the needle. This arrangement produces a very uniform tension on the thread.

A presser-bar, R, operates to hold the goods firmly when not being fed or moved along. This presser-bar extends beneath and approximately parallel with the needle-bar. It is provided at suitable intervals in its length with notches, through which the needles may pass. Posts It extend upwardly from the presserbar through guides r on the frame of the machine. Arms R2 extend from the posts It near the tops of the latter and are rigidly ICC IIO

y shafts from which the needle-bar and shuttle-l lcarrier are actuated, and that through the inatxed thereto. Cams R on the shaft I7 are adapted to be brought in Contact with the arms R2 during the rotation of said shaft, and thus elevate the presser-bar. The presser-bar is returned to a position to bear upon the goods by spring of", coiled about the posts R', and bearing at one of their ends against shoulders on said posts andthe other against the guides r.

It will be seen that by my improvement a continuous rotary motion is imparted to the termediate mechanism operated by said shafts dwells are caused to occur in the movements' of the needles and shuttles. What I claim as niyinvention, and desire to 'secure by Letters Patent, is-

1. The combination, 'with the needle-bai` I, of the link I', lever l2, blook I, disl 1*, shaft l, upon which said disk is mounted, the( gear-Wheel l, also mounted on said shaft, the
