QUILTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,657, dated May 1, 1883.

Application filed January 26,1883. (No model.)-

city, county, and State of New York, have ina horizontal section of said plate ou vented certain new and useful Improvements in Quilting-Machines, of which the following is a specification. f

, This invention has reference to an improved quilting-machine in which the quilting is accomplished by a single gang of needles that is placed either at a suitable angle of inclination or .parallel to the direction of motion of the fabric to be quilted.

The invention consists in the combination of a vertically-reciprocating needle-bar having a single gangof needles,alongitudinally-guided feedcarriage,a feeding mechanism-and a carriage-reciprocating mechanism of special construction, arranged in connection with said feeding mechanism, as hereinafter described and claimed. y y j In the accompanying drawings, Figure 1 .represents a side elevation of my improved.

quilting-machine. Fig. 2 is a plan 5 Fig. 3, a rear elevation. Figs. 4 and 5 are respectively a side elevation, partly in section, on line x x, Fig. 5, and a vertical transverse section of the mechanism by which reciprocating motion is imparted to the feed-carriage. Fig. G represents a detail vertical transverse section and a longitudinal section of the shaft and pinion by which motion is imparted tothe feed-rollers. Fig. 7 is a plan of a inoditied construction of thequilting-machine, with the needle-bar arran'gedparallel to the direction of motion of thfefabric. Fig. S is a detail side view of the 'grooved plate by which reciprocatory motion is imparted to the feed-carriage, and Fig. 9 is line y y of. Fig. 8. y

Referring to the drawings, A representsl the supporting-frame of my improved quiltingmachine. The frame is made of oblong shape,

reference indicate correand provided at one end with upright and forward-bent standards A', which serve to guide the vertically-guided needle-bar B, having a single gang of needles. y The needle-bar B is reciprocated by any approved mechanism. The needle-bar Bis supported by the standards A at an angle of forty-tive degrees across the fabric to be quilted, in which case one of the supporting-standards A is lengthened and the other shortened, so as to provide for this position of the'needle-bar, as shown in Figs. l and 2. Y

The frame A is provided at its longer sides with longitudinal guide-rods a, which are supported in fixed brackets a. To these guiderods a the feed-carriage C is applied at both ends by upright standards C', which carry in suitable bearings the feed-rollers G2 C3.

The fabric to be quilted is wound upon a roller, b, supported in suitable bearings at one end of the feed-carriage (l, and retained by a suitable tension device. It is then conducted over a guide-roller, b', to the first pair of feedrollers, (12and then transversely across the feed-carriage C to the second pair of feed-rollers,-G3, at the opposite end of the feed-carriage. The second pair of feed-rollers, G3, receives intermittent rotary motion from a fixed wormsegment, d, on the flanged wheel D at the end of the driving-shaft D', said worin-segment engaging at each revolution ot the drivingshaft a pinion, D2, the teeth of which are placed at an angle of inclination to the axis of the pinion-shaft. A flange, d', extends' around that part of the circumference of the wheel D which is not taken up bythe worm-segment d, so as to engage the pinion D2 and stop the same until the worm-segment d engagesintothe teeth of the pinion and movesytzhe` samev around its axis. The shaft of the pinion D2 turns in bearings of the frame A, and is provided at the rear end with a .gear-wheel, c, which meshes with the gear c'bu a longer shaft, c?, arranged below the shaft of the pinion D2, and parallel thereto, the shaft c2 turning in bearings of frame A, and of one of the upright standards C of the feed-rollers O3, as shown in Fig. l.

On the shaft e2 is arranged a gear-wheel, e3, which meshes with a gear-wheel, 6*, attached to the shaft of the lower feed-roller, C2. gear-wheel e3 is adapted to slide longitudinally on the shaft c2, together with the carriage C, the shaft being provided for this purpose with a longitudinal groove, j', and thc hub of the gear-wheel with a fixed spline, f', which moves in the groove f, as shown in detail in Fig. 6. The gear-wheel c3 is provided with a grooved The IOO

collar, c5, which is secured to a corresponding f2. -By means of this connection the pinion is.

compelled to traverse, with the supportingstandards C of the feed-rollers C3, along the Y shaft e2 without being prevented from rotating with the same, so as to transmit thereby intermittent rotary motion to the gear-wheels at the ends of the feed-roller shafts and an intermittent forward feed to the fabric.

The feed-carriage C receives also intermittently reciprocating motion Asimultaneously with the revolving motion imparted to the feedrollers in a direction at right angles to the direction of the feed of the fabric. This reciprocating motion is imparted by means of a special mechanism which forms the essential fea-- ture of my invention. This mechanism is shown in detail in Figs. 4 and 5, and consists of a short shaft, g, that turns in bearings of one of the standards A of the needle-bar, and

' gear-wheel gaon the shaft g, as shown clearly in Fig. 2. The shaft g is made of two` parts, which are connected by a universal joint, g4. The outermost end of the jointed shaft g is guided in parallel grooves g5, having semicir cular connecting portions, of a slide-plate, gG, which latter is guided in parallel horizontal a-nges g7 of the upright plate g. The horizontally-guid ed plate g6 is arranged with a central row of horizontal projecting pins g8, which are engaged by the teeth ofa pinion, 99,' near the end of shaft g. The pins g8 are arranged for this purpose at such a distance from each other as to admit the proper meshing of the pinion therewith. The serncircular end portions of the grooves g5 serve to guide the shaft* from the upper to the lower groove, and vice versa, in following the pinion gg around the pins g8. The shaft g is guided near the pinion g9 along the inclined slot gw of a fixed plate, y, said inclined slot serving to facilitate the turning of the pinion g around the end pins from the upper into the lower groove.

rlhe intermittent rotary motion of the shaft g imparts, by the pinion 99 and pins g8, intermittent reciprocating motion to the slide-plate g, which is pivoted by an extension-arm, g', to the feed-carriage G. The latter receives therebyintermittent reeiprocatin g motion, that takes place simultaneously with the lateral motion which is imparted to thc fabric to be quilted by the feed-rollers and their transmitting mechanism. When both the fabric and feed-carriage are at a point of rest the needles descend and make astitch, which is repeated, so as to produce zigzaglines of stitches over the entire fabric, which lines touch at the. corners, andgive thereby the appearance ot' continuous diagonally-intersecting lines of stitches, as shown in Fig..2.

When it is desired to quilt the fabric in larger or smaller squares of stitches the guidepla-te gG is lengthened or shortened by inserting between or removing from the two end sections of the saine, which are connected by overlapping shoulders and clamp-screws, in-

termediate pieces, gw, having additional center pins, as shown in dotted lines in Figs. 4, S, and 9.

It' twice the size of the regular squares is desired to be made to that which is usually made on the machine, one or more intermediate needles are removed and a corresponding length of section inserted into the slide-plate gs, so as to produce thereby the required degree of reciprocating motion for the feed-carriage. For this purpose the grooves of the slide-plate have to be equal in length to one-half of the diagonal of the squares formed by the zigzag lines of stitches.

In place of arranging the needle-bar at an angle of forty-five degrees, it may be arranged at any other oblique angle, and also, if desired, parallel to the direction of the feed, as shown in Fig. 7, in which case the supporting-standards of the needle-bar are of equal length. In this case, however, the quilting is not accomplished bylongitudinal zigzag lines that touch each other at their corners, but by diagonally-intersectinglines of stitches. Consequently the guide-plate gG has to be equal in length to the width of the fabric to be quilted. The lines of stitches cross each other at right angles by the reversing of the motion of the feedcarriage, as indicated in dotted lines in Fig. 7.

The remaining accessories-such as shuttlecarriers, shuttle-motion, thread-tensions, e.- are not shown in the drawings, as they are of the same construction as those usually employed in quilting-machines heretofore in use.

By my improved construction a single gang of needlesproduces the uniform quilting of the fabric, either in longitudinal zigzag lines which touch each other at the corners or by diagonally-intersecting lines of stitches, as shown respectively in Figs. 2 and 7, and by means of a mechanism which produces a regular intermittent reciprocating motion of t-he feed-carriage simultaneously with the intermittent lateral motion ofthe fabric.

Having thus described my invention,l claim as new and desire to secure by Letters Patent- Y 1.
