SrizCIFICATION forming part Of Letters Patent NO. 340,863, dated April 2'7, 1886.

Application filed October 29, 1885.

.To aZZ whom it may concern.-

Be it known that 1, DAVID H. COLES, a citizen of the United States,residing at New York, in the county and State of New York, have 5 invented new and useful Improvements in Quilting-Machines, of which the following is a specification.

My invention relates to improvements in quilting-machines; and it consists in certain i novel features of construction, which are fully pointed out in the following specification and claims and illustrated in the accompanying; drawings, in which-- Figure 1 is a plan or top view, the parts to the right of the vertical shafts m and a being omitted. Fig. 2 is a horizontal section in the plane :0,Fig. at. Fig. 3is an endview. Fig. 4is vertical section in the plane g y, Fig. 2. Fig. 5 is a vertical section in the plane z 2, Fig. 1, the rollers E F and I. J being shown in section. Fig. 6 is a vertical section in the plane .v 00, Fig. 1. Figs. 7 to 18 are details, which will be described as the specification progresses.

Similar letters indicate corresponding parts.

In the drawings, thelet-ter A-designates the frame, and to it are secured the guides a, for the needle-bars b, to which the necessary upand-down motion is eommunicat ed by the arms 0, mounted on a shaft, B, running through the 0 whole length of the machine and having its hearings in the frame A. On one end of this shaft is secured an arm, (1, Figs. 1 and 6,which is connected by rods e f and bell-crank lever g with an eccentric, 72, mounted on the shaft 0, Figs. 2 and G. This shaft isintermittently rotated, as will hereinafter be described. The shaft 0 also carries an eccentric, 2', Figs. 2 and 5, which is connected by a rod,j, with an arm, is, secured to the rock-shaft D, on which are mounted a series of arms, Z, which are connected to the shuttle-carriers m by links at. When the shaft 0 is rotated, the desired reciprocating motion is given to the shuttle-carriers, causing them .to slide in the guides 0, 5 Fig. 5, which are secured to the frame A.

I do not desire to confine myself to this construction of needle and shuttle operating devices, as any other suitable devices may be applied, and an intermittent motion be im- 5o parted to them.

Serial No. 181,286. (No model.)

The machine shown in the drawings contains all the appliances for tufting, and will turn out tufted quilts of the pattern indicated in Fig. 17,in which the tufts are quincuncially placed; but this pattern may be essentially varied, by any skilled operator. To produce this pattern itis necessary, first,to introduce the quilting and tu fting material under the needle. Second, to give the quilting and tufting material together the necessary feed motion, so 6 that the operationof the sewing device will cause the needle to stitchthrough both the desired number of times and then stop. This feed motion I term the primary feed. Third, the whole must then be fed forward to form 6 the desired length of tuft. Fourth, the tuft must then be cut off by the cutting device. Fifth, the quilting material alone must then be fed forward and sideward independent of the stitch-forming mechanism and the primary feed, until the place for a new tuft comes under the needle, when the whole operation is re peated by the continued action of the machine. This operation and the third operation are accomplished by means of the mechanism which 7 1 herein refer to as independent cloth-feed mechanism.

I will now proceed to describe these operations in their order and in detail.

7 First. The quilting material, which gener- 8o ally consists of two thicknesses of cloth, with a layer. of cotton-batting between them, is first passed between the feed-rollers E and F, then between the upper feed-bar, G, and the under feed-bar, H, and then under the feed- 8 roller J, and between the same and the feed roller I. The rollers I and J have their bearings in standards F, which can be adjusted by means of the screws F". This adjustment is necessary to properly control the operation 0 of these rollers. The tufting material may consist of one or more strands of cord, yarn, or strips of cloth, and is wound on spools K, which turn on a rod, 1), loosely placed in hangers,'q, secured to the frame of themachine. It then passes through guides r,which project from the hangers, and then through openings 8, Fig. 7, in the upper feed-bar, G, which brings it directly under the needle. Both the quilting and the tufting material'are 100 then grasped between the feed-bars G and H. These feed-bars run the whole length of the machine, and while both move in a horizontal plane. the upper one, G, also moves vertically, and this vertical motion is controlled in one direction by springs 16, Fig. 8, and in the other by the feed-bar-lifting mechanism,which will be presently described. Said upper feed- Lar, G, is provided at each end with a hub, a, from which project lugs aagainst which press vertical rods 10, having bearings a',Figs. 2 and 4, in the frame A, and subject to the action of levers b, which are pivoted at c and rest on cams d, mounted on the main shaft L. As the latter revolves, the feed-bar G is raised by means of the cams d, the levers b, and rods w, and depressed by the springs t,which will cause the same to grasp the work, as above described.

Second. The tufting material is firmly held against the quilting material between the feedbars and directly under the needle, as above described. The feed-bars, together with both materials,are now caused to move horizontally in a closed curve by a step-by-step motion, while the sewing mechanism also operates and the needle descends and stitches through both materials, producing asmall circleor polygon of stitches, (see Fig. 16,) which pass through and serve to hold together both materials. \Vhen this has been accomplished,both the primary feed and the sewing mechanism stop. This intermittent circular or polygonal feeding and sewing is produced as follows: On the outer end of the main shaft L is mounted a mutilated gear-wheel, M, which engages a pinion, N, secured to one end of a short shaft, 6, which has its bearingsin the frame A,and the other end of which carries a cog-wheel, f, which meshes into the pinion O on the shaft C, Figs. 2, 3, and 4. In the example shown in the drawings these gears are of such proportions to each other that the shaft 1, from which the parts necessary to the second operation receive their motion, makes twelve revolutions for every revolution of the mutilated gear-wheel M, carried by the main shaft L; or, in other words, the teeth remaining on said mutilated gear-wheel are sufficient to cause the shaft 0 to make twelve revolutions, after which the said shaft stands still during that part of the revolution of the mutilated gear in which the blank space comes opposite to the pinion N. To control thelastdescribed operation positively,and to prevent the motion of any of these parts during the time when the blank space passes the pinion N, a flange, g, is formed, Figs. 2 and 3, on the outer side of said pinion, and from it projects an eccentric pin, h, carrying an anti-friction roller. Vhen the pinion N has reached the end of the toothed portion of the gear-wheel M, this eccentric pin it will be opposite the opening of a cam-groove, 1, formed in the side of the mutilated gear-wheel, and as the latter revolves the cam-groove will pass over said eccentric pin h, thereby preventing the pinion N and all parts connected with it from turning until the toothed portion of the gear M is again reached,when the cam-groove will release the eccentric pin h, and the pinion N will again be free to turn, subject to the action of the teeth on the mutilated gear M. On the shaft 0 is mounted a cam, Q, Figs. 2 and 5, which acts on an anti-friction roller, i, secured to one end of alever, j, turning on a pivot, it, while the other end of the lever j connects by a rod, 1, with a dog, on, on the stud a, and carrying a pawl, 0, which engages a ratchetwheel, 1), secured to a cog wheel, g, which meshes into a pinion, r, mounted on the shaft B, Fig. 5. This shaft, which has its bearings injournals s, secured to the frame, carries a bevel gear, t, Figs. 4 and 6, at each end, which mesh into similar gears, a, mounted on the upright shafts '0, having bearings 10 in the frame, and carrying at their upper end disks a To these disks are secured other disks, b", by means of bolts 0", Fig. 15, passing through slots (1 From the disks If project upright eccentric pins 0 which pass first through the hubs f at each end of the lower feed-bar, H, Figs. 8 and 14, and then through the hubs a at each end of the upper feed-bar, G, Fig. 8, so that when the upright shafts o, to which the eccentric pins 0 are attached, are rotated both the upper and lower feed-bars and the work which is held between them are carried around in a curve similar to the one traveled by the upright eccentric pins 0. As previously described, each revolution of the main shaft will cause the needle to descend twelve timesthat is, the sewing mechanism will make twelve stitches, which, by the peculiar motion given to the work by the feed-bar,will fall in a circle. To form a complete circle of twelve stitches it will be necessary that the feed-bars be carried around in the said circle in eleven steps or feed motions, so that when the needle descends the twelfth time it will strike the spot at which itstarted and complete the circle. In other words, to make a circle or polygon of stitches it is necessary to make one more stitch than there are feed motions. This is accomplished as follows: The shaft 0, which actuates the stitch mechanism, is geared to a shaft, 0, in such a manner that the latter will make one revolution less than the former for every revolution of the main shaft L. In this example the shaft 0 makes twelve revolutions,while the shaft C will make only eleven. The shaft 0 carries the cam Q, and each revolution of this cam will turn the lever j on its pivot against the action of the spring 9', Fig. 5, and will cause the ratchet-wheel, which has eleven teeth, to be moved forward one tooth, so that when the shaft Ohas made the eleven revolutions described above the ratchet-wheel p and the cog-wheel attached to it will have made one complete revolution,while the shaft R, which carries the pinion r,'which has only half as many teeth as the cog-wheel q, will have made two revolutions, thus causing the upright shaft 2) to make two revolutions also,

and to feed twice around the circle described by the eccentric pins e To obviate any liability of breaking the thread as the work is fed around the second time, by the needle again passing down through one of the stitches made before, I cut an odd number say eleven-teeth in the ratchet wheel 1;, which will insure the passage of the needle through a new place in the work at each stitch, and

make a polygon of stitches. (Shownin Fig. 16 three times natural size.) In the machine shown the curves made by the eccentric pin c are ofa very small diameter just large enough to securely sew on thetufting; but it is evident that they may be increased to any size and the work quilted in a number ofpatterns without tufting. For instance, a pattern like 7 Fig. 18 could be produced without any essential change in the mechanism.

Third operation-fecding the work forward to make length of tuft: After the second operation the relative position of the work and the feed-bars will be as shown in Fig. 9 that is, the tufting material will be sewed onto the quilting material near the end of the former, and the needle will be in its upper position, while the work will still be grasped between the feed-bars. It is now necessary to feed the work forward the desired distance, so as to bring the tufting material under the cutting device in such a position that when the latter operates, which will be the next operation, it will cut a tuft of proper length. To admit of the necessary forward feed, the upper feed-bar must first be raised to its upper position, so as to release the work, while the cutting device, which is loosely attached to this feed bar, must also be raised to permit the free motion of the work. The raising of the upper feed -bar is accomplished as described in the first operation by the cam d, mounted on the main shaft L, while the cutting device is raised. by a somewhat similar cam, a", Fig. (3, mounted on the same shaft and acting on a lever, v", on which rests the rod 10*, abutting against a lug, a, on the cutting device. This cam is of such a shape that it will raise the cutting device just clear of the work during this operation and into proper position for action, which will form the next operation. The work, as has been described, is held between the feed-rollers I J, which are caused to move together by llangd gears It, and are intermittently rotated by a pawl, i Figs. 1 and (5, acting on the ratchet-wheel j This ratchet-wheel is secured to a cog-wheel, It, which turns loosely on a stud, Z, projecting from the frame, and meshes into a pinion, m, mounted on the trunnion n of the roller J. On the main shaft L is mounted a cam, 0, Figs.'2 and 5, which acts on an arnnp secured to a shaft, (1 which also carries the arm 0, Fig. 6, and the latter is connected by a rod, 8 to a dog, i carrying the pawl The cam 0 is so shaped that during this operation it will cause the work to be moved forward only sufficient to form a tuft of proper length. The

effect of its further rotation will be described in another operation. At the end of the third operation the relative position of the work, the feed-bars, and the cutting device will be as shown in Fig. 10.

Fourth operationcutting off the tuft: To the back of the upper'feedbar, which is L- shaped. are 'loosely attached the cutting-bar S and the guide-bar T, and the whole is held together by the action of the spring 1), whose pressure may be regulated by the nuts 0 screwed on bolts (1 which projectfrom the upper feed'bar. (See Fig. 7.) The cuttingbar and the guide-bar are also connected to each other in a like manner by spring-bolts 6 By reference to Figs. 7, 12, and 13 it will be understood that while the horizontal motion of the feed-bar is also shared by the cuttingbar and the guide-bar, the feed-bar may be moved vertically independently of the others, and vice-versa. In one end of the cutting-bar S is a notclnf, Fig. 8, which embraces the upper rounded end, 9, of a lever. U. This notch is of such a shape that when the cuttingbar is down in the position shown in full lines in Fig 8 and in Fig. 9 it will permit the horizontal motion of the cuttingbarasit is carried around with the upper feedbar, but when raised to the position for cutting (shown in dotted lines in Fig. 8 and in Fig. 10) the sides of the notch f will closely embrace the upper roundedend g of the lever U, and the cuttingbar will move laterally when this lever, which is pivoted at 71 is acted on by the grooved cam 1' mounted on the main shaft L, Fig. 2. When the work has been fed forward sufii ciently to form the tuft, as described in the previous operation, and the feed and cutting bars have been properly raised, the tufting material will rest in the cutting-notches j,

formed in the lower edge of the cutting-ban Fig. 13, and also in the notches ldof the guidebarT. (SeeFigs.10,12, and 13.) Thegrooved cam i then acts on the cutting-bar, moving the same lateral] yin the direction of the arrow marked on it in Fl 8, while the feed and guide bars remain stationary, thereby shearing off the tufting material and finishing the tuft.

Fifth operationfeeding the quilting material forwardand sideward until the place for a new tuft comes under the needle: After the cutting operation has been completed, the cam it raises the cutting and guide bars intothe position shown in Fig. 11, and the quiltingmaterial is now free to move, subject to the action of the feed-rollers E F and I J. The latter now receive a simultaneous lateral and revolving motion. The revolving motion is caused by the cam 0 which must be of such shape or configuration that while revolving it will effect the motions predicated to it. The quilting material is thus caused to be fed forward, while the sideward motion of the feedrollers is imparted to them by a forked arm, Z Figs. 1 and 4-, mounted 011 the upper end of an upright shaft, m having its bearings a IIO in the frame A. The lower end of this shaft carries a lever, 0 Fig. 2, one end of which is toothed and engages a toothed segment, 19 on the end of a shaft, (1 having its bearings r in the frame, and which receives a slightly-rotating motion by the action of the grooved cam engages a grooved collar, J, on the trunniong of the feed-roller F, Figs. 1 and 4. The feed-rollers E and F are connected by flanged gears h 6, Figs. 1 and 6.

When the last operation has been completed and the quilting material has reached the position for a new tuft, the upper feed-bar will againdescend, clamping the tufting material onto the quilting material, and the five operations above described will be renewed.

A view of a portion of a quilt produced by the above-described machine is shown in Fig. 17.
