PEGIFICATION forming part of Letters Patent No. 456,727, dated July 28, 1891.

Application iled September 2% 1888. Serial No. 286,110. (No model- 4To all whom it may concern:

Be it known that I, MATTHIAS KooH, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Sewing-Machines, of which the following is a specification.

I Will describe a sewing-machine embodying my improvement in detail, and then point out the various novel features in the claims.

In the accompanying drawings, Figure lis a plan or top viewof the machine embodying my improvement, a certain support for the fabric being broken away to expose parts which otherwise would be concealed by it. Fig. 2 is a vertical section taken on the plane of the dotted line or. a', Fig. l, but made on a larger scale. Fig. 3 isa vertical section taken on the plane of the dotted line y y, Fig. l.

Fig. 7 is a vertical section showing certain mechanism which` may be used instead of that used in Fig. 5. Fig. S is a vertical section showing certain mechanism which may be used instead of that used in Fig. 5. Fig. 9 is a View of a piece of fabric quilted.

Similar letters of reference designate corre1 spondin g parts in all the figures.

A designates the body or base-frame of the machine. It may be of any suitable construction. Two long arms B are mounted upon the base-frame, one at each side thereof. The free ends of these arms support an intermediate bar or s.retcher B and carry the needles and their appurtenances.

32 designates the needle-bar; B3, the needles, which may be of any suitable number, arranged in any desired manner. The needle-bar reci procates vertically. It is provided with a number of shanks or rods B4, extending upwardly through brackets B",secured to the bar or stretcher B. These rods B1 have secured to them collars, to which are pivotally connected links B, which are also pivotally connected to arms extending from a rockshaft B, supported by the arms B. The rock-shaft BT is oscillated by means of rods B1", pivotally connected to arms extending 55 from the rock-shaft and to disks aliixed to a rotary shaft B, supported by the arms B. The shaft B1 is shown as constituting the driving-shaft of the machine, being provided with fast andloose pulleys B10 B11. `These pul- 6o leys are not, however, mounted directly upon the shaft, but upon a sleeve B12, arranged upon the shaft and adapted to be interlocked therewith by means of a clutch, consisting of two parts b h2, one of which is affixed to the shaft and the other to the sleeve bymeans of aspline, so that while it maybe moved longitudinally upon the sleeve,neither it nor the sleeve can have any independent rotation. Alever h3,

fulcrumed to a stationary part of the ma- 7o chine framing and having a bifurcatc end provided with pins engaging with a groove in the hub of the part lf2 ot' the clutch, serves as a convenient means for adjusting the part b2 of the clutch into or out of engagement with the part h of the clutch. The parts b b2 may be constructed in any approved manner to engage. For instance, one may be provided with a pin or pins and the other with a corresponding hole or holes in the opposite 8o I have not deemed it necessary to not move into different positions or travel over the fabric during the quilting.

The fabric to be quilted is sustained by a carriage C. This carriage consists of two side pieces c and a number of intermediate bars or stretchers provided with two pairs of rollers c1125 c c1.. The fabric to be quilted passes between one This carriage is roo pair of these rollers and then through the other pair. The rollers c"l c5, constituting one pair, are geared together by gear-wheels C8, and the rollers c c7, constituting the other pair, by gear-wheels 09, affixed to their journals. It will be seen that. one of each pair of rollers is furnished with a man-crank cw. The carriage C is supported by a carriage D. The carriage D consists of side pieces d d2 and intermediate stretchers cl3. The side pieces d of the carriage D may obviously be 5 connected below the body or base-frame of the machine by cross-pieces or stretchers, and this is equally true of the side pieces d2 of the carriage D. It will be seen that one portion of the carriage D is at each side of the base-frame of the machine. Each portion of the carriage D is provided with a hooked tongue di, engaging with the adjacent side piece of the base-frame. Each portion of the carriage D is also provided with two wheels or pulleys d5, which travel along ledges or tracks provided on the sides of the base-frame. Each portion of the carriage is also provided with wheels or pulleys d, bearing against the sides of the base-frame. The carriage D travels in the direction of the length of the arms B.

The carriage D is provided with rollers C27, upon which are supported the side pieces c c2 of the carriage C. The carriage C will be moved with the carriage D in the direction of the length of the arms B and transversely to the length of theV needle-barpbut it can also have a motion independently of the carriage D in a direction transverse to the length of the arms B and parallel with the length of the needle-bar.

It will be readily understood that by reason of the fact that the fabric is supported by the carriage C the fabric will be capable of movement in any desired direction in a horizontal plane beneath the needles.

I have now described the underlying principle of the machine. It is well known in the state of the art that the needles may be supported by a carriage, so as to travel over the fabric, instead of supporting the fabric upon a carriage, so as to have universal motion iu one plane. lt now remains to describe the mechanism for imparting motion to the two carriages and for imparting motion to the rollers with which the carriage C is provided.

I will first explain the means for imparting motion to the carriage D. Each portion of the carriage D has affixed toit a toothed rack d8, extending iu the direction of the length of the arms B. TWith the racks ds gear-wheels di engage. These gear-wheels d" are mounted upon a shaft D', supported by the base-frame of the machine. By rotating the shaft D in the desired manner the requisite movement of the carriage D will be secured. The shaft D has affixed to it a gear-wheel dw. En gaging with the gear-wheel d10 is a rack du, which reciprocates horizontally and in the direction of the length of thearms B. This rack serves as a means for transmitting motion to the shaft D. The rack d in effect constitutes a rod. Said rod is provided with pins CX12 (Z13, which coaet with two rotary pattern-cams D2 D3, aliixed to a rotary shaft D4. The shaft D4 derives its motion through a large gear-wheel du, affixed to it and engaging with a small gear-wheel C115, which is mounted upon a shaft D5. The shaft D5 has a ratchet-wheel DG seeu red to it. A pawl CZG engages with the ratchet-wheel and is carried by an oscillating arm loosely mounted upon the shaft D5. This arm is oscillatedfby a rod d, worked by an eccentric d, affixed to a shaft D7. The shaft D7 receives a non-intermittent rotation by means of gear-wheels d d20, afiixed one to it and the other to the sleeve B12. The patternwheels D2 D3 are so shaped as to impart to the carriage D the requisite motion for any particular pattern. These pattern -wheels may be changed for others when different patterns are desired.

l will now explain the mechanism for imparting motion to the carriage C independent-ly of the motion which is transmitted to the carriage D. The side pieces c c2 are provided with toothed racks fr, which engage with pinionsE, affixed to a shaft E. This shaft is journaled in fixed portions of the machineframe and is provided with a long gear-wheel E2, rigidly secured to rotate with it. V-ith the gear-wheel Eza toothed rack-bar E3 engages. This rack-har reciprocates in a direction transverse to the length of therarms B, and by reciprocating imparts a rotary movement to the shaft E in one direction or the other, as may be necessary for the production of any desired pattern. Although the shaft E is supported in bearings arranged upon the fixed portion of the machine-frame, it is capable of a sliding movement in the direction of its length, so that it may move with the carriage C in the direction of the length of the arms B. This is necessary in order that its pinions E may maintain engagement with the racks r of the carriage. The pinions have collars, which are fastened by set-screws or otherwise to the shaft. These pinions bear one against the outside of each of two projections with which the carriage D is provided. lVhen this carriage D is moved, it transmits longitudinal movement to the shaft E by its bearings against the pinions. The rack-bar E3 is operated by a gear-wheel E, affixed to a shaft E5, mounted in bearings in the fixed portion of the machineframe. This gearwheel and its shaft rotate always'in one direction.

E designates a pattern-wheel affixed to the shaft El", so as to rotate therewith. The rackbar E3 is provided with two pins e3 e, which bear against the periphery of the patternwheel E, The patternwheel is thus enabled to reciprocatetherack-barand transmitmotion in reverse direction transversely to the length of the arms B to the carriage C. The shaft E5 derives motion from a shaft E7, the latter IOO IIO

being provided with a gear-wheel E8, which engages with the gear-wheel E4. The shaft F.7 is also provided with a bevel gear-wheel E9, that engages with a bevel gear-wheel E10, affixed to the shaft D5. The shaft E7 thus derives motion from the shaft D5. As the shaft D5 derives motion from the ratchet DG and pawl d 15, it operates intermittingly. Its intermittent motion being transmitted to the carriage C and carriage D, these carriages, as

well as the needles, operate with an intermit tent movement.

I will now describe a modification of 'the mechanism for producing the intermittent motion of the carriages C and D. This mechanism may be substituted for the ratchet D" and pawl dw and the appurtenances of these parts. This modified mechanism is shown in Fig. 7. The shaft D7, instead of havin g an eccentric and eccentric-rod combined with it for operating the pawl all, is provided with a bevel gear-wheel (1,25, which meshes into and drives a bevelwheel cl2, aiiixed to a shaft d2". This shaft also has affixed to it a bevel gear-wheel C128, which engages with a bevel gear-wheel d2, aiixed to a shaft ddl. The shaf t d3() has affixed to it an eccentric gear-wheel dgl. This engages with another eccentric gear-wheel CW, affixed to a shaft di. The shaft cl3 has affixed toit a worm dit. This worm meshes into a worm-wheel d, affixed to the shaft D5. The eccentric gears (1516132 produce a substantiallyT intermittent motion of the shaft D5.

In Fig. 8 I have shown ameehanism exactly like that illustrated in Fig. 7, excepting only that the gears c1316?? are not eccentric, but are circular gears, and the shaft d33 has substituted for the worm dL a thread (F6, which is horizontal throughout, but interrupted at one point in its circumference, and an inclined segment of thread dal, which is opposite the interruption in the thread cl3". These threads dal dal engage with the teeth of the wormwheel 35 on the shaft D5. The thread da locks the worm-wheel C135 against rotation, except when its interruption comes opposite said wheel. At this time the thread-segment Z3? engages with the worin-wheel and moves it one tooth forward, after which the thread dfb' again engages with the worm-wheel and locks it.

I have now described the general characteristics of the machine. To conduce to a clear understanding, I will add that the dotted line F designates the fabric. The fabric is held during the sewing by the fecdrollers c4 c5 c I have also provided clips G for holding that edge of the fabric which is nearest the needles. These clips may be readily understood by reference to Fig. 6. They comprise, severally, bars g, mounted upon the side piece c2 of the carriage C and extending thence upwardly and thence horizontally toward the needle-bar. Each bar g has pivotally connected to it a lever g. The lever g is above the horizontal portion of the bar g and is pivoted or fulcrumed between its ends.

The end which is the nearer to the needle-bar coacts with the adjacent end of the bar g to grip the edge of the fabric. The other end and the corresponding extremity of the hori' zontal portion of the bar g have interposed between them a spring g2. This spring forces upwardly the end of the lever g,upon which it acts, and thereby causes the other end of the lever to grip the fabric. An eccentric g3 is affixed to a shaft g4, so as to be capable of actin g upon that arm or end of the lever upon which the spring g2 acts. By rotating the shaft g4 in one direction the eccentric g3 will be made to permit the spring g2 to act. By rotating the shaft g4 reversely the lever g may be oscillated so as to release the fabric. The shaft g4 is common to the eccentrics of all the clips G and is provided with a handle g5, by which it may be conveniently oscillated to operate all the clips.

The machine as described is intended for working the fancy pattern F which is represented in Fig. 9, and not for performing the diagonal lines of stitching F2 shown in said figure. During the quilting of the fancy pattern F the feed-rollers are motionless. After the fancy pattern shall have been quilted upon such portion of the fabric as extends between the pair of feed-rollers c4 c5 and `the other pair of feed-rollers cG cT one pair of feedrollers will be rotated to feed this finished portion of the fabric along and present another portion of the fabric between the two pairs of rollers, in order that it maybe quilted `with a continuation of `the same fancy pattern. This motion of the feed-rollers may be produced by means of a hand-crank am. One of the feed-rollers of each pair may be forced toward the other to maintain a grip upon the fabric. I have shown that I may combine with a pair of feed-rollers lneans whereby they maybe forced into contact with any desired pressure. This may be understood by reference to Figs. 1 and 2. I have shown these means combined with the rollers c6 c7. These rollers are journaled in sliding boxes fitted in horizontally-extending grooves 'or housings formed in the side pieces c c2 of the carriage C. Between the boxes supporting the two rollers springs h are arranged. These springs tend to force the rollers c6 away from the roller c7. The boxes of the rollers c have combined with them pins 7i', which are capable of sliding lengthwise of the side pieces c c2 of the carriage. The outer ends of these pins h impinge against eccentrics 7a2, mounted upon a shaft H. This shaft has aiiixed to one end a hand-crank h3. By rotating the shaft II the eccentrics h2 may be made to force the rollers c( against or toward the rollers c7 with any desired pressure.

I have shown the carriage Cas provided with rollers I I2. The fabric to be quilted ICO IOS

IIO

may be wound upon one of these rollers and y which is illustrated as serving as a take-up roller, may be rotated from the roller c5 through the agency of a pulley t', affixed to the roller c5, a pulley t", affixed to said roller 12, and a belt i12. lt will be seen that the roller c4 has affixed to it at one end a bevel gearwheel c2, which engages a bevel gear-wheel c, affixed to a shaft C22. The bevel-gear c21 is secured to rotate with the shaft 022 by means of a spline or feather; but the bevelwheel 021 is capable of sliding lengthwise of the said shaft c2? The bevel-wheel C21 is fitted in a bearing C23, which is a fixture on the carriage C. This connection of the bevel gear-wheel 021 with the shaft G22 affords provision for theV movement of the carriage C, and yet enables the shaft c22 to transmit rotary motion to the roller c4. The shaft 022 has rigidly affixed to one end a bevel gear-Wheel 024, and the shaft is secured in a bearing c25 on one of the portions of the carriage D. This gear-wheel and its shaft therefore move with the carriages C and D in the direction of the length of the arms B, but do not partake of the movement of the carriage C in a direction transverse of the length of the arms B. The bevel-wheel c2* engages with a bevel gear-wheel 026, arranged upon a shaft J, which is journaled in the fixed portion of the machine-frame. The bevelwheel c26 is secured to rotate with the shaft J by means of a spline or feather. The bevelwheel c2G is supported in a bearing in one of the portions of the carriage D, and hence when this carriage moves this bevel-wheel-is moved with it lengthwise of the shaft J. Obviously the shaft J, although stationary, is thus enabled to transmit rot-ary motion to the bevel- -wheel c2G and thence to the roller c4. The shaft J has affixed to one end a gear-wheel j', which engages with a gear-wheel j?. This wheel jg is mounted upon a stud, which is supported in a swinging arm, the latter being loosely supported upon the shaft J. arm is similar to an arm K, (represented in Fig. 3,) and hence its construction maybe readily understood by reference to the arm K and the appurtenances of the latter. The gear-wheel t7'2 engages with a gear-wheel js, affixed to a shaft jl. The object of supporting the gearwheel t7'2 upon the arm is to enable it to be substituted by a gear-wheel of larger or smaller size and still preserve the transmissiblity of motion from the gear-wheel .7'3 to the gearwheel j. The gear-wheel js has affixed to it a bevel-gear jf, which engages with a bevel gear-wheelj, affixed to a shaftjT. The shaft j? has affixed to it a ratchet-wheel js. A pawlj coacts with this ratchet-wheel. The pawl ji is carried by a leverjlo, which is hung loosely upon the shaft j?. This lever is oscillated by means of a rod j, which is moved longitudinally in one direction by an eccentric or cam jm and in the other direction by a spring j. The cam or eccentric f2 is affixed to and rofates with the shaft D?. The rod ju is connected to the leverj10 by means of a link jm.-

The link jl* has an adjustable connection ythreads of the needles.

This swinging y has affixed to it an arm fo.

with the lever by means of a bolt passing through said link and into a slot extending lengthwise of the lever. The rod j is not free at all times to move forward under the inuence of the springjl to follow the receding periphery of the eccentric or cam jm, as itis controlled in the forward movement by a pattern-wheel jl. The pattern-wheel is of circular form, but has at one point in its periphery a long notch. The time of the rotaltionrof this pattern-wheel is such that the periphery of the pattern-wheelj15 the fancy pattern is being worked. By the time the notched portion of the pattern-wheeljl5 comes opposite the pin 7'13 the fancy pattern has been completed. While the notched portion of the pattern-wheelis passing the pin js, and only .during this time, the rodj11 is free to follow the eccentric j. During. this period no pattern is being worked and the feed-rollers c4 c5 are automatically rotated `through the agency of. the pawlj9 and ratchetj8 to move the fabric forward far enough to present a new surface for the fancy pattern to be worked upon. lVhile the fabric is being thus fed to present a new surface to be worked upon certain lines of straight stitchingparallel with one edge` of the fabric are produced, which is preferable to cutting the These lines are not, however, intended to form any part of the pattern, but may be removed by trimming the fabric.

The pattern-wheeljl"l not only serves to effect the rotation of the feed-rollers cJl c5 at the proper time, but `it has lthe additional function of stopping'the rotation of the shaft D5, whereby the carriages C and D are moved. I will now explain how this is done. The shaft A link ,f2.1 connects this arm with a leverj, which is hung loosely upon the shaft D5. It will be readily understood that when the notched portion of the pattern-wheelj15 is opposite the pinj1B of the arm jui and the eccentric j and springj13 are permitted to reciprocate the rod j the lever f2 will simultaneously be oscillated, and its upper end, being in proximity to the pawl d1, will throw this pawl out of engagement with the ratchet-wheel D6.

The rotation of the pattern-wheelj15 will now be explained. It is affixed to ashaft f1. This shaft has affixed to it a gear-wheel ,742. A pinion f3 engages with the gear-wheeljfg. This pinion is affixed to a shaft, which has also affixed to it a ratchet-wheel f4. The

Icq

IXO

ratchet-wheelji4 is driven by a pawlf, aflixed to an arm, which is oscillated by an eccentric jm, which is affixed to the sleeve B12, that is arranged upon the shaft B.

I will now describe a stop-motion. L designates a rock-shaft provided with handles Z Zi whereby it may be conveniently rocked. The rod Z3 is pivotally connected to the handle Z at one end and supported at the other end in a guide Z4. This rod is provided with forks and constitutes a belt-shifter, Awhereby the main driving-belt may be carried from one to the other of the fast and loose pulleys B10 B11.

I will now describe how the shaft L may be oseillated automatically to operate the helt shifter rod Z3. The shaft L has affixed to it an arm ZH, which is shown as having a V- shaped upper portion that may be engaged by a pawl or dog Z5, pivot-ed at one end to a fixed portion of the maehine-frameaud drawn downwardly by a spring Z. This arm Z24 has connected to it a link Z7, which is also pivotally connected to a lever ZS, which is fulerumed between its ends to the fixed portion of the machine-frame and is shown as having a bent or offset portion at the lower end. The shaft E5 is shown as having afiixed to it a disk or wheel Z, provided with a toe or projection similar to a ratchet-tooth. lVhen the shaft nearly completes a rotation, the projectionfrom the disk Z5 will oscillate the lever ZR, so as to cause it to oscillate the arm Z2* toward the spring l", actuating the pawl Finally the projection of the disk Z swings the arm Z2* so far over that the V-shaped under side of the pawl Z5 acts in conjunction with the V- shaped upper end of the said arm Z24 to throw the arm Z24 quickly over toward the spring ZG. This will effect the oscillation or rocking of the shaft L to such a degree as to cause the shifting of the belt from one to the other of the fast and loose pulleys B10 B1'. This oecurs at the time that the fancy pattern is conipleted on any one portion of the fabric, and the fabric in consequence thereof requires to be removed to present a new surface. The pawl Z5 of course is provided with a stop-such, for instance, as a pin ZlO-to prevent it from being pulled too far downwardly by the spring ZG when not supported by the arm Z24.

When the fabric is fed so as to cause the stitching of the straight lines near one edge of the fabric, the mechanism for imparting motion to the carriages is rendered inoperative. This is done by loosening certain gears,

as will hereinafter be explained.

I will now describe how the machine may be disorganized for quilting a fa'ney pattern, such as the pattern F', Fig. 9, and organized to quilt diagonal lines F2, Fig. f). The gear- Wheel (Zw is disengaged from the shaft D5 in the present instance by loosening a screw, which secures its hub to the shaft. This change prevents the shaft D5 from transmitting motion to the carriage D through the rack-bar d, gearwheel CZO, shaftD, and gearwheel d. The gear-wheel di" is new loosened by disengaging the screw which secures it to the shaft D. his change leaves the shaft D free to rotate under the control of other mechanism. The pattern-wheelj, when'adj usted so that its notched portion will be opposite the pinjls, is disengaged from the mechanism which imparts motion to it by loosening the eccentricj40 from the sleeve B12, which is arranged upon the shaft B9. This may he done by loosening the screw, which in the present instance passes through the hub ol' the said eccentric and secures it to said sleeve. Thus the pattern-Wheel j15 will be made to remain idle, with its notched portion opposite the pin js. The eccentric j and the spring j will therefore be left free to effect the rotation of the feed-rollers c4 c5. The gear-Wheel E8 is also disengaged from the shaft ET inthe present instance by slackeningascrew which passes through the hub of said gear-wheel and impinges upon the said shaft. This change prevents the shaft D?l from transmitting motion to the carriage C through the pattern-wheel E, rack-bar E3, shaft E', pinions E, and the racks fr, arranged upon said carriage. For the diagonal lilies of stitching the carriage C has no motion imparted to it independently of the carriage D, bntis, in effect, apart'of the carriage D for the time. The carriage D is now operated by a different mechanism, deriving motion from the shaft D5. In this mechanism there is a gearwheel k, affixed to one end of the shaft D5 and engaging with a gear-wheel Zt', which is supported upon a stud projecting from the arm K. The arm K is hung at the upper end pon the shaft D5. Its stud, which supports the gear-wheel Zu', iits in a slot extending lengthwise of said arm. The stud may therefore be adjusted lengthwise of said arm and toward and from the gear-wheel Zr.. The arm K at the lower end has in it an arc-shaped IOO slot, which is concentric with the axis of the this arc-shaped slot and serves to secure the arm K in different positions. The gear-Wheel k engages with a gear-wheel 7,12. The object of the arm K is to provide for the substitution of a change-gear, or, in other words, a gear of a dilferent size, instead of the gear la', to vary the speed of the motion, which will be transmitted to the gear-wheel 702. The gear-wheel Zr? is mounted loosely upon the shaft D4. A pattern-wheel or cani 7e3 is also loosely mounted uponthis shaft. This pattern-wheel and the gear-wheel Ztaale secured upon a sleeve common to both, or otherwise secured to rotate in unison independently of the shaft D1. The pattern-wheel 7f3 operates in connection with two pins Ztl, extending across opposite points in its periphery from a rod L5. The pattern-wheel 7e3 thus imparts a reciprocating motion to the rod Zt. The rod Z5 is constructed at one end to form a rackbar, which engages with a gear-wheel k6,

affixed to a shaft k7. The shaft 70T has also affixed to it a gear-Wheel 7c8. This gear- Wheel 7a8 engages with a gear-wheel 7c". The gear-Wheel 7c is affixed to a shaft 71:10, having secured to it at one end a beveled gearwheel 7CH. The shaft 7&9 is supported in a movable bracket 7tlg. This bracket issecu red to a fixed portion of the machine-frame by means of screws or bolts passing through slots extending transversely to the length of said shaft. This enables cliange-gearrto be employed, as the gear 7d) may be shifted and replaced by another upon the shaft 7am. The bevel-Wheel 7c engages with a bevel-gear 7&3, affixed to aV shaft 7&4." Vhen the bracket 7912 is adjusted into a different position, the bevel- Wheel 7&3 may be adjusted lengthwise of the shaft 7c and secured in a different position.

The shaft 7c has affixed to one end a bevel-` wheel 7&5, which engages with a bevel-Wheel 7cm, affixed to the shaft D. As the shaft D transmits motion to the carriage D through the gear-wheel d, with which said shaft is provided, and the racks C78, with which said carriage is provided, it is obvious Ythat the shaft D5 now transmitsaY reciprocating inotion to the carriage D under the control of the pattern-Wheel or cani 7c3.. Y'

When the machineris organized as just described, the carriage Dand the carriage@ with it will beinoved in the direction of the length of the arms BY under control of the patternwheel 7c3, andthe feed-rollers c4 cwill simultaneously be rotated through the agency of the pawl j" and ratcliet-Wheeljs. The result Yof the combined movements imparted to the fabric by and the movement of the carriages in the direction of the length of the arms B Willbe an oblique movement of the fabric beneath the needles. Oblique lines of stitching, such as those I?? in Fig. 9, Will therefore be sewed or quilted upon the fabric.
