QUILTING- MACHlNE.

SBECIPICATION forming part of Letters Patent No. 323,584, dated August 4, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, XVILLIAM Koon, of the city, county, and State of New York, haveinvented a new and useful Improvement in QuiltingMachines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the ac companying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to an improvement in that class of quilting-machines for which Letters Patent have been granted to me hearing date July 1.1, 1882, No. 250,991, and January 30, 1883, No. 27l, l75.- By means thereof I avoid the necessity of causing the entire width of fabric to be quilted to traverse the direction of its feed at an oblique angle or to move laterally across the entire width of the machine, and,in addition to superior advantages in the construction and operation of the machine, obtain with two diverging rows of needles similar effects to those produced by means of a series ofneedles arranged in two rows, one behind and alternating with the other.

In the accompanying drawings, Figure 1 is a plan view of the principal portion of the machine; Fig. 2, a plan on an enlarged scale of the gearing for producing the combined lateral and longitudinal feed of the fabric; Fig. 3, a sectional elevation on line m m of Figs. 1 and 2; Fig. l, a detached view in elevation of one of the shuttle-carriers and its rod.

A represents the bed-plate of my machine, supported upon a suitable frame, and at each end of which standards B B B B are erected to carry the transverse shafts which actuate the shuttle-bars, the needle-bars, and. the thread controlling devices. The standards B B are preferably flanged,and are connected at the top by at-ransvcrse flanged bar, E,forming a stiff overarching frame.

The main driving-shaft F is mounted in suitable bearings upon the bed-plate A to em tend across from side to side of the machine. Upon this drivingshaft and at each side of the machine a bevel-wheel, F, Fig. 1, is secured to gear with counterpart bevel-wheels, F on the end of a short shaft, G, mounted in suitable bearings upon the bed-plate at an angle with the main shaft. The axes of the two shafts G and G are upon converging lines which, if extended, will intersect at a right angle with each other at a point at the front of the machine about midway its width. Two converging rock-shafts,H H, are mounted in the upper part of the machine in bearings supported by its frame-work, to extend each parallel with one of the shafts G G directly over it. These rock-shaftsare of a length to extend from the middle of the front end of the machine at a right angle with each other to its outer side edges. The journal-bearings for their front ends depend from the transverse bar E upon a hanger-plate, S, so that said front ends overhang the fabric led through the machine. Each shaft H is geared to an eccentric on one of the shorter shafts G by means of a suitable connecting-rod, G, (see Fig. 3,) so as to be made to oscillate by the ro- A ,tation of the latter in the customary manner.

At each end of each rock-shaft H a vertical bar, I, is mounted to reciprocate freely in the frame-work, and is connected by a link, a, to an arm, a, projecting from the rockshaft, so that the oscillation of the shaft will cause these vertical arms to slidenp and down in unison. Two long needle-bars, J J, fitted with a series of needles, N XV \V, properly se cured thereto, are fastened to the vertical bars I I, both in the same horizontal plane, and each parallel with one of the roclc-shafts'lrl, so as to extend, consequently, at a right angle with each other from a common intersecting point in the middle of the front of the machine outwardly to its sides, to cover the full Width thereof.

Above the rock-shafts H H and the needlebars J J actuated thereby are mounted the customary thread directing and controlling devices from which a separate thread is led and supplied to each needle. As these devices and their arrangement and support upon the frame-work of the machine differ in no essential particular from similar devices in the machines heretofore in use, it is not neces sary herein to describe them.

The sliding shuttle-carriers K K are fitted to slide, in the customary manner, back and forth in suitableparallel ways, each under one of the needles V in a right line from front to rear parallel to the line of movement of the fabric to be quilted. Each carrier is secured to the end of a rod, K, extending rearwardly to a transverse bar, L, mounted to slide freely to and from the needles. The outer end of each carrier-rod K is inserted in a slot cut in the bar L, and is fitted with a lateral spring, I), to secure it in said slot, and which may be fitted with a thumb-piece, b. By releasing the spring and withdrawing the rod K the shuttle carried thereby may be drawn to the rear of the machine within ready reach to adjust or replace the bobbin therein. The transverse shuttle-bar L is made to reciprocate in proper synchronism with the movement of the needle-bars by means of two or more link-connect-ions, L L, which couple it to arms L upon a rock-shaft, L, which is actuated by an cecentric, L, on the main shaft. (See Fig. 1.)

The fabric to be quilted is drawn horizontally across the machine from front to rear in a right line bisecting the angle formed by the two horizontal needle-bars J J from a pair of rollers, M M, (between which the two facings and interposed wadding are introduced,) to a set of parallel drawing-rollers, M M which, by their frictional engagement with the quilted fabric, feed it forward. These several rollers are allmounted in atraversing carriage, N, substantially as is described in my patent of July 11, 1882, whose frame embraces the frame and bed-plate of the machine, and which is fitted to reciprocate horizontally at a right angle to theline of motion of the fabric upon suitable studs or pins, N N, projecting from each side of the frame.

The first pair of rollers M M turn in brackets depending in front of the machine from the front end of the carriage. The feed-rollers M M turn in suitable bearings at the rear end of the carriage, one of said rollers, M being mounted in a vibrating frame, which permits it to swing and be forcibly held against the main roller M by means of springs 0. An intermittent motion is communicated to the main roller M by means of a ratchet-wheel, R, (see Fig. 3,) secured thereto, which is actuated by a pawl, B, upon a lever, BF, pivoted to the carriage, and which is oscillated by engagement with a cam, R, on the main shaft.

The feedcarriage N is made to traverse in the machine from side to side thereof at a right angle to the line of movement of the fabric and in line parallel with the main shaft by means of an eccentric upon a transverse shaft, 1, in a supplementary fixed frame, A, extending out from the bed-plate A. Said eccentrlc engages a connecting-crank rod, d, pivoted to the carriage N. The shaft Pis made to r0- tate intermittently in unison with the intermittent movement of the pawl R, actuating the feed-roller M, by means of a worm-segment, e, upon a flanged wheel, Q. This wormsegment meshes at each revolution with the teeth of a pinion, T, on a rotating shaft, 1?, mounted parallel with the shaft P, the shafts P and 1? being geared together by spur-wheels ff on said shafts and an intermediate pinion, f. The flange h on the wheel Q extends around so much of the periphery of the wheel as is not embraced by the worm-segment e, and, engaging the teethon the pinion T, serves as a stop therefor when it is not actuated by the segment. This means of Obtaining an intermittently-revolving motion of the cam, by which the reciprocating motion of the feedcarriage of the machine is produced, is described in my Letters Patent of July 11, 1882.

In the operation of my machine, when the main shaft F is set in motion its rotation will, by means of the bevelgear F F and secondary shafts G G, produce an oscillation of the rock-shafts H H, and a vertically-reciprocating movement of the two diverging horizontal needle-bars J J. Simultaneously the rockshaft L will be made to oscillate, by reason of its connection with the eccentric L on the main shaft, and the shuttle-bar L and entire series 'of shuttle-carriers K K be made to reciprocate horizontally under the needles W \V in harmony with their movement. At the same time the rotation of the cam R on the main shaft F will produce an intermittent oscillation of the pawl-lever R and thereby cause the fabric to be drawn forward by the rollers M M? uniformly and at regular intervals between each stitch, while the revolution of the segment 6 upon the same shaft will produce intermittently, in manner as described, a lateral movement of the carriage N, carrying the rollers so as to move the work transversely by successive steps between each stitch at a right angle to the direction of its feed, first in one direction for a suitable distance and then in the other, an adjustment of the movement being obtained, as required, by

changes in the gear. This lateral movement in one direction or the other between each stitch is synchronous with the forward feed between each stitch. By this combined lateral and longitudinal feeding of the work, (which is not a new feature in the art of quilting,) in combination with my novel arrangement of two gangs of needles at an angle with each other and the line of movement of the fabric, each needle is made to produce a zigzag row of stitches along the length of the fabric with a comparatively short lateral to-and-fro movement of the work. As these zigzag rows meet at their angles, a diamond-shaped pattern is produced on the quilt, as illustrated at y in Fig. 1. By producing a differential feed of the fabric in manner as is well known to the art the zigzag rows are} converted into curved rows, as illustrated at 2, Fig. 1. I am also en abled to reach all the needles very readily for threading them.

By combining the shuttle-carriers with rods of different lengths I am enabled to move the shuttles for all the needles bya single shuttlebar, irrespective of their varying distances from said bar, and am also enabled to readily withdraw any one or more of the shuttles without interference with any other portion or function of the machine.

Instead of making the needleframe stationary and moving the fabric laterally under the needles,it is evidentthat the fabric may be fed forward without lateral movement, and that alateral to'andfro movement may be imparted to the needlebars to produce the same result; also, that the angle of divergence of the needleha-rs may be varied in different machines to produce different patterns of work.

I claim as myinvention-- 1. The combination, in a quilting-machine, of two needle-bars arranged at an angle with each other and each carrying a series of needies, with dcvi ces for feeding the work beneath the needles, substantially as described.
