MACHINE.

SPECIFICATION forming part of 'Letters Patent No. 421,584, dated February 18, 1890.

Application filed April 19, 1886.

To @ZZ whom it may concern:

Be it known that I, MATTHIAS KOCH, of w New York, in the county and State of New York, have invented a certain new an d useful Improvement in Sewing-Machines, of which the following is a specication. My improved sewing-machine is designed to sew patterns of various designs upon fabric. I employ a gang of needles which work 1o in unison and all sew similar patterns. The goods to be sewed are borne upon a carriage which has a four-way motion, or a motion fore and aft and from side to side of the machine. The goods have also an independent forward feed.

I will describe the machine in detail and then point out the novel, features in claims.

In the accompanying drawings, Figure 1 is a plan or top view of a quilting-machine embodying my improvement. Fig. 2 is an end View thereof. Fig. 3 represents a pattern .which may be sewed on theY machine. Figs. '4, 5, 6, 7, and 8 are face views of certain pattern-wheels used in the machine. Fig. 9 is a front elevation showing more clearly certain carriages, portions of the machine being omitted. Fig. 10 is a perspective view, on an enlarged scale, illustrating my improvement. Figs. 11 and 12 illustrate in detail certain features of the machine, the parts being shown in different positions in the two figures. Fig. 13 is adiagrammatic View showing one course of the stitches. Fig. 141: is a perspective view,

- on an enlarged scale, looking toward the left of Fig. 10.

Similar letters of reference designate corresponding parts in all the figures.

A designates the main shaft, to which motion may be imparted by a belt on a pulley A. This shaft is journaled in suitable bearings in a pillar a, extending upwardly from the bed of the machine, and also in side portions B I3 of the frame of the machine. A crank a is mounted upon the end of thek main shaft beyond the portion B of theframe. This crank imparts motion to afrock-shaft a2 through an intermediate crank-rod a3. The rock-shaft a2 is journaled in suitable bearf lings in the portions B B of the frame and imparts motion to a needle-bar a4, in which a gang of needles is secured. Motion is transf Serial No. 199,412. (No model.)

mitted from the rock-shaft to the needle-bar by arms a5, rigidly keyed to the rock-shaft and pivotally connected to links a, which are in turn pivotally connected to vertical sliding rods a7, working in suitable guides a8 in the frame. The needle-bar is rigidly secured to the rods 0.7. Upon themain shaft adjacent to the crankV a is an eccentric 0.9, operating through an eccentric-rod a10,'rock 6o shaft a, and rods L12 toimpart motion to shuttle-drivers, which, together with the shuttles and shuttle-races, may be of the usual or Yany desired construction. I have shown a presser-bar a, operated by. toes a on the p rock-shaft, coming in contact with projections @15 on the upper ends of rods al, to which the presser-bar is secured, as usual.

As the features so far described do not constitute part of my invention` I have referred 7o to them thus briefly.

C C C2 C3 designate, respectively, patternwheels by whichy the movements of the carriages upon which' the goods are borne are regulated. C4. designates apattern-wheel for regulating the forward feed. to the goods when said carriages are at rest. As shown, the wheels C C govern the forward-and-back movement of the goods and the wheels C2 C3 govern the sideto-side movement ofthe goods; 8o but it is to be understood that they may be arrangedin any desired order. All five of these pattern-wheels are rigidly keyed to a horizontal shaft D, j ournaled in suitable bearings in posts extending upwardly from the 8 5 base of the machine. An intermittent rotary motion is imparted to this shaft, and consequently to the patternwheels, by means of a ratchet-wheel d', keyed to the shaft D outside the pattern-wheel C, which ratchet-wheel is 9o actuated by a pawl d2, mounted on a rocking arm cl3. A crank-rod d4, pivot-ally connected to the arm cl3 and receiving motion from an eccentric d5 on the main shaft, actuates said arm. Each rotation of the main shaft causes the pawl d? to move the ratchetwheel a distance equivalent to the length of oneof its teeth. This motion is so timed as to occur when the needles are raised out of the goods, or, in other words, no motion of the carriages 10o occurs when the needles are operating on the goods.

I I designate carriages for the goods to be sewed. The carriage I supports the goods and has a movement fore and aft the machine imparted to it. The carriage I supports the carriage I and has a motion from side to side of the machine imparted to it. By moving these carriages in a manner hereinafter to be described a movementuniversall y forward and back and from side to side in one plane may be imparted to the goods beneath the needles.

The carriage I consists of two side pieces I2 I3, secured together by tie-rod t' and a transverse casting i2. In downwardly-extending portions i3 at the front of the machine is hung a delivery-roller fi" for the goods. J ournaled in suitable housings in upwardly-extending portions i5, also at the front of the machine, are presser-rollers i, the upper of which is pressed down upon the other with a yielding pressure by means of springs 7. The resistance of the springs l may be varied by screws i8, as shown. To the rear of the needles feedrollers 119 (shown as geared together) are journaled in suitable housings in other upwardlyextending portions im of the carriage. The pressure of these rollers may be regulated similarly to the rollers if. The goods pass from the delivery-roller between the presserrollers, beneath the needles, between the feedrollers, and upwardly onto a take-up roller tu, onto which they are wenn d. The take-u p roller i is journaled in bearings in upwardly-extending arms im, forming part of the carriage I, at the rear of the machine. Motion is imparted to this roller, as shown, by a cord and weight 13, the cord being' wound upon a spool fil upon the end of the roller-joinnal.

The carriage I consists of two side port-ions I4 I5, secured together by rods @'15, which rods extend loosely through slideways in the portions B B of the frame. The portions IIl I5 of this carriage are between the portions I2 I3 of the carriage I and the portions B B of the frame, and are` provided upon their outer surfaces with anti-friction rollers or bowls il, some of which are arranged near the top of said portions I'l I5 and others near the bottom thereof. The carriage I is supported by and may be moved along upon these rollers or bowls. It will be readily seen that when the carriage I is moved. backward and forward no motion is imparted to the carriage I". 0n the contrary, when the carriage I is moved from side to side it carries with it the carriage I, because of the flanges on the rollers or bowls '1116. By means of these two carriages the goods are caused to be moved either forward and back or from side to side, as desired. They also have a direct forward feed independent of the motion of the carriages, which will be described later.

I will now describe the means for imparting motion to the carriages.

The pattern-wheel C regulates the motion of the carriage I toward the rear -and the pattern-wheel C the motion of said carriage toward the front. The pattern-wheel C2 regulates the motion of the carriage I to the left and the wheel C3 the motion of said carriage to the right of Fig. l. One of the wheels C C may operate in conjunction with either of the wheels C2 C3, or one of the wheels C2 C may operate in conjunction with either of the wheels C C', whereby a universal movement of the goods beneath the needles may be produced.

T designates a friction-brake mounted on a screw t and consisting of a pad of rubber or other suitable material. The screw is mounted in a bracket t and may be adjusted to vary the pressure of the brake upon the pattern-wheel C.

It will be borne in mind that the patternwheels are interniittently rotating in unison and in the same direction. They transmit motion to the carriages as follows:

J J2 JS J4 are bars extending fore and aft the machine close to the pattern-wheels. Each of the bars J J 2 J 3 J1 is composed of two seetions j j. The longer of these sections or ,7' extend near their rear ends through guides j2 on a portion of the frame of the machine. Springs jg, surrounding the rods between said `guides, and shoulders ji on the rods tend to force the rods toward the front of the machine. 'lhe sections j bear near their front ends rollers or bowls j5, which may be acted upon by cams J7 J8 JJ JO, mounted on the main shaft, to force the rods toward the rear. Pivotallyconnected near one of their ends to the sections j of the rods are arms e, which arms are loosely hung upon shafts e e2 e3 e, j ournaled in suitable bearings in posts extending upwardly from the base of the machine. These arms bear pawls el() near their free ends, which are adapted to en gagethe teeth on ratchet-wheels e5 e e7 e8, keyed to the shafts c', dac. Pivotally connected near one of their ends to the sections j of the rods are other arms c. These arms are likewise hung on the shafts e', dac. The upper ends of these arms e extend beneath the pawls ell. \Vhen these arms e are moved far enough in one direction, they will lift the pawls out of engagement with the teeth on the ratchet-wheels; Vhen the ratchet-wheel e5 is rotated, it transmits motion through the shaft e to a gearwheel e, mounted'on said shaft. The gearwheel e meshes with a gear-wheel. cl2, mounted on the shaft c2, which gear-wheel meshes with another gear-Wheel el, mounted on a shaft G, extending from side to side along the front of theunachine. This shaft is journaled in the side portions B '3' of the frame, and also in bearings in a post s, extending upwardly from the base of the machine. Between the portions B l oi' the frame bevel gear-wheels g are mounted on the shaft G. These bevel gear-wheels mesh 'lhese screw-shafts ex- IOO IIO

ISO

tend thro ugh screw-nuts secured in lon gitudinal slots in the casting t2, extending between the side portions 12,113 of the carriage I.

, When, therefore, the ratchet-wheel e5 is roscrew-shafts g2 to rotate in a reverse direc-l tion and cause the carriage I to move t0- ward the front of the machine, because the rotation of the gear-wheel emisvhen rotated by the ratchet-wheel e6, in a reverse direction to that which it received when rotated through the medium of the gear-wheelel1 and ratchetwheel e5. The ratchet-wheel e7 is rotated by means similar to the ratchet-wheels e5 e6, and transmits motion to a gear-wheel g3, mounted on the shaft e3, which gear-wheel meshes with a gear-wheel g on the shaft c4, which shaft is journaled near one end in the port-ion B 0f the frame. Adjacent to the portion B ofthe.

frame the shaft e4 is screw-threaded and engages a tapped hole in thev sidev portion I4 of the carriage I. The rotation of the ratchetwheel e7 causes the screw-shaft e4 to rotate in a direction to move the carriage I toward the left of Fig. l. The ratchet-wheel e8 ,is actuated similarly to those described, and, being mounted directly on the shaft e4, it necessarily causes the said shaft to rotate in a reverse direction to that which it received when rotated through the medium of the ratchet-wheel e7 and gear-wheels g3 g4, whereby the carriage l will be caused to move toy the right.

It is necessary, in order to sew a pattern such as I have illustrated, that the motions of the carriages should be variable, or, in other words, should be capable of moving different distances in a given direction, vIn

Asewing the clover-leaf iigure shown, for instance, the carriages will move a portion of the time directly toward the right or left. At other times the carriage I will move directly toward the front or rear, and at other times the movement will be a combined side-to-side and forward or back one. lVhen this combined movement transpires, it will be apparent that the deviation from aline running parallel with or at right angles to the direction of forward feed of the goods will be very slight in some instances. In order to provide for these slight deviations and produce a symmetrical ligure, I have, for convenience, divided each stitch into ten arbitrary equal parts, so that the slightest deviation from a right line which a stitch may take will equal one-tenththe length of a stitch taken at right angles to the line from which the first stitch devia-tes. Such deviations from a right line may equal any number of tenths of the length of a stitch which may be desired, according as the curve or angle of the pattern be slight or great.

The deviations of the stitches from a right line are produced as follows: Each figure of the pattern which I have illustrated in Fig. 3 contains one hundred and forty three stitches. Each of the pattern-Wheels C C C2 C? is divided radially into one hundred and forty-three sections c, corresponding to the number of stitches in the pattern. quently when the pattern-wheels have made one complete revolution each of the needles has sewed a Icomplete iigure. Each separate movement of the pattern-Wheels. occasioned by the ratchet and pawl moves each of the Wheels a distance equal to the length of one of the sections c on the periphery of the wheel. Each of the said pattern-wheels is also divided into eleven sections c', which are formed by concentric circles whose centers are identical with those of the patternwheels. The combined width of the ten inner of these sections represents the length of a single stitch taken in the goods on a right line, and each one of the sections represents one-tenth of the length of a stitch. The periphery of each of the wheels is indentedl at intervals, the depth of each indentation corresponding to the nulnber of tenths of the length of a stitch which it is desired that the stitch shall deviate from a right line-as, for instance, if the indentation equals the width of one of the sections c, the stitch will deviate one-tenth the length of a stitch from a right line. If the indentation be equal to the width of iive of the sections c', the deviation ofa stitch from a right line will equal five-tenths the length of a stitch, and so on. In the diagrammatic Fig. 13 I have have illustrated this operation more clearly.

Upon the sections 7' of the rods J', dac., are pins or studs jm. These pins bear constantly upon the pattern-wheels, against which they are forced by the springs j3. As thepatternwheels rotate the pins jl@ drop into the notches in the pattern-wheels. It will be perceived that Las a pin jldrops into a notch the bar J dac., vof which the pin forms part, is shot forward by the spring js, causing the arm e to rock and the pawl ew, which is actuated by the cam J7, rbc., to actuate the ratchetwheel cf", the., with which it acts in conjunctin. In the example of my invention shown each of the ratchet-wheels e5, dce., has one hundred teeth, and each complete rotation of the ratchet-wheel will cause a movement of the goods in a rectilinear plane V.a distance equal to the length of ten stitches. Therefore each ten teeth on the ratchet-wheel represents a movement of the goods equal to the length of onestitch. Therefore, if the pin (7'16 drops into a notch in the pattern-Wheel.

whose depth equals the combined width of ten of the sections e on the pattern-wheel,

Conse- IOO IIO

the ratchet-wheel will be moved a distance equal to ten teeth, and in like proportion for each notch into which the pin drops according to it-s depth. The cams J 7, 85e., operate to throw the bars J dac., backward at each rotation of the main shaft sufficiently far to cause t-he pin jl to move out of the notch into which it has just previously been sprung as far as the tenth circumferentialsection c. (Indicated by dotted outline in Figs. 4C, 5, 6, and 7 It is obvious that only one of the wheels C C and only one of the wheels C2 C3 can be operating to move the carriages at a time. A change from C to C or C2 to C3, and a consequent reversal of the movement of either of the carriages, as the case may be, is produced by lifting the pawl el() which has been actuating a given ratchet-wheel out of engagement with said wheel, as previously eX- plained. This is effected by causing the pin jl of its corresponding bar J dac., to ride up from the tenth circumferential section onto the periphery of the pattern-wheel C, dac., with which it acts, by means of the rotation of said pattern-wheel itself, which is camshaped, as at c2, to admit of this, whereby the portion j of the bar J is moved so far to,

the rear of the machine that the arm e9 comes in contact with the pawl and moves it out of the teeth. n I have shown sliding joints j in the bars J dsc., whereby, when this movement occurs, -the portions j will be moved without imparting movement to the portions j, and consequently to the arms e. I have shown the operation of these features of my improvement more clearly in Figs. l1 and 12.

Vhen it is desired to feed the goods directly forward, the motion of the carriages is stopped in the manner described. The pattern-wheel C is then brought into operation, by which the feed-rollers are caused tofeed the goods forward. The needles then sew a straight line of stitching in the direction of the length of the goods. Such straight lines may be sewed as part of the figures or between diiferent figures, as the pattern being sewed may require. The wheel C4 operates through a bar J 5 similar to the bars J dac., to transmit motion to a ratchet-wheel f, mounted on a shaft f', journaled in bearings in a post extending up from the base of the machine, and also in the portion B of the frame. Loosely mounted upon the shaft f is a bevel gear-wheelj'2.l This gear-wheel is provided with arib extendinginto alongitudinal groove fain the shaft f in such manner that the gear-wheel may slide to and fro on the shaft, but will at the same time be rotated therewith. The hub of the gear-wheel extends through an opening in one arm of a frame f4, which is rigidly affixed to the carriage I. A collar f5 on the hub retains the gear-wheel in position. This gear wheel meshes with another bevel gear-wheel f, sim ilarly secured in another arm of the frame f4, extending at approximate right angles to the `arm first named. The hub of the gear-wheel f6 is extended somewhat and provided with a rectangular socket, into which extends loosely the squared end of a shaft f7, journaled near its other end in one arm of afrarne fs, rigidly secured to the carriage I. Upon the shaft fT is keyed a bevel gear-wheelji, which meshes with another bevel gear-wheel flo, mounted on a shaft fu, journaled inV another arm of the frame f8, and also in the carriage I. Upon the shaftfl is keyed a gearwheel f, 'which meshes with a gear-wheelfm, mounted on the journal of one of the feedrollers i9. The gear-wheels j"12 fla are so proportioned as to give the required length of stitch when the goods are fed forward. It will be readily seen that by this arrangement the parts will be in a position to operate the feed-rollers in whatever posit-ion the carriages I I occupy.

It will be seen that in my improvement the carriages I I constitute a support for the goods to be sewed. It will likewise be observed that there is a relative movement between the sewing mechanism and said support for the goods.

Vhat I claim as my invention, and desire to secure by Letters Patent, is
