QUILTING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 317,996, dated May 19, 1885. Application tied June 24, iss-i. (No model.)

To all whom it may concern.-

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

I will describe a quilting-machine embodying my improvement, and then point out its various improvements in claims.

In the accompanying drawings, Figure l is a front view of a quilting-machine embodying my improvement. Fig. 2 is a horizontal section thereof, taken on the plane of the dotted line x x, Fig. 1. Fig. 3 is a transverse section thereof7 taken on the plane of the dotted liney y, Fig. l, looking in the direction indicated by the arrows at the ends of said line. Fig. 4 is a transverse section of the same, taken at the plane of the dotted line z z, Fig. l, looking in the direction indicated by the arrows at the ends of said line. Fig. 5 is a transverse section of the same on a larger scale, taken on the plane of the dotted line o o, Fig. 2, and looking in the direction indicated by the arrows at the ends of said line. Fig. 6 is a sectional front view of certain parts. Fig. 7 is a horizontal section of certain parts. Fig. 8 is a longitudinal section of certain parts. Fig. 9 is a transverse section of the parts represented in Fig. 8. Fig. l0 is a top view of the needle-bar and part of a skirt, and Fig. ll is av top view of the shuttle-plate.

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

A designates the main frame of the machine, consisting, essentially, of a base-piece erected on suitable legs. This main frame, as here shown, is stationary.

B designates a carriage consisting, essentially, of a plate traveling on rollers B, interposed between it and the main frame of the machine. This carriage has the needle-bar arranged on it, and is provided with a tailpiece, B2. From the tail-piece B2 extend studs provided with rollers B, which impinge against the periphery of a cam, B4, having a series of facets or steps that are concentric, but at different distances from the center. This cam is affixed to an upright shaft, B5. On this shaft B5 is also arranged a worm gearwheel, B6.

Motion is transmitted to this worm gear-wheel, and hence to the shaft B5, by Imeans ofa worm, Bl, on a shaft, C, which forms the driving-shaft of the machine. The driving-shaft G is shown as provided with fast and loose pulleys C C2 and a fly-wheel or hand wheel, C3. It rotates continuously while the machine is in use. In this example of my improvement the cam B1 is intended to have eighteen facets or steps, and the worm gear-wheel B6 is to have a like number of teeth. The worm gear-wheel is to have a movement equal to the dist-ance from center to center of adjacent teeth, and the cam is to move a distance equal tothe length of one facet or step for each rotation of the worm B7. It will be understood that the cam BfL imparts an intermittent motion to the carriage B. An arm B8 extends upward from the carriage B and horizontally over the same. It has af- 4fixed to its horizontal portion brackets B9.

In these brackets rods B10 are tted to'slide in a direction transverse to the arm BB, and, in this example of the invention, vertically.

D designates the needle-bar. It is fastened to the lower ends of the rods B10 and moves with them. Motion is imparted to the needlebar by means of cranks D on a rock-shaft, D, which is journaled in bearings a on the brackets B9, and also in bearings a on brackets B, affixed to the arm B8. The cranks D are connected by links D2 to collars D3 fastened by set-screws to the rods B10.

0n one end of the rock-shaft Dlz is a crank, D4, to which is connected a rod, D5, which is v also connected to an eccentric, D5, arranged on a shaft, D6. This shaft D6 is jonrnaled in brackets D7 erected upon the carriage B. This shaft therefore moves with the carriage besides having a rotary movement. Its rotary motion is derived from the driving-shaft C. The driving-shaft G has affixed to the end which is adjacent to the shaft DG a ring or socket, Du. This ring or socket, as here shown, is fastened to the shaft C by means of a set-screw, b. This ring-or socket extends beyond the shaft C and receives within it the end of the shaft D6. The end of the ring or socket which projects beyond the shaft G has a transverse notch, c, and

1 the end of the shaft Ds which enters such ring or socket has a similar transverse notch, d. `Into these notches c dl a plate, D8, extends, thereby looking the shafts C and DG together,

ICO

so that the former will impart motion to the latter, but'yet so that a lengthwise motion of the one relatively to the other will be possible. The plate Dz3 is shown as secured by rivets to the shaft D6.v rlhe end of the ring or socket D, which projects beyond the shaft C, has applied toitasurrounding-band, D. Ascrew, e, passes through this band and impinges against the ring or socket Du. By forcing the screw e farther into the band D, the portions of the ring or socket D which are on opposite sides of the notch c may be pressed nearer together to compensate for wear.

Having now explained the motions of the needle-bar and the manner in which such motions are imparted to it, it behoovesme to describe the shape of the needle-barand the manner in which the needles are arranged upon it.

D10 designates the needles. They are shown as arranged in notches f in the longitudinal edges of the needle-bar. They may be secured there by screws or otherwise. lf zigzag lines of sewing are to be produced, but one row of needles will be used. All which are then used will be arranged in the notches f of one edge of the needle-bar. When, however, zigzag lines of stitching are to be sewed, so as to meet and form diamond-shaped gures and other analogous figures, the needles will be arranged in two rowsone row along each longitudinal edge of the needle-bar.

With the organization of the machine which I have shown the needles when used in two rows will be so disposed that the needles of each row shall be opposite the spaces between the needles of the other row.

The machine is intended for quilting circular or curved fabrics and articles, such, for

instance, as ladies skirts.

The feed mechanism of the machine is such that the longer edge of the curved articles-for instance, the lower edge of a ladys skirt-will be caused to move through the machine more rapidly than the shorter edge. I shall presently describe this feed mechanism in detail.

As the machine is to be used for sewing circular fabrics andarticles, the edges of the needle-bar are made flaring and occupy approximately the position of radii of the circles of the fabrics and articles. Throughout part of the length of the bar I may use two rows of needles,- and throughout the remainder of the length of the bar I may use needles in a single row. In this way I can produce a variety of patterns.

I will now describe the shuttle operating mechanism.

E- designates a number of shuttle-races supported on bars fastened to brackets E erected upon the carriage B.' In the upper part of the brackets E rods E2 are arranged so that they can slide forward and backward. They derive motion from cranks or arms E3, extending from a rock-shaft, E, Links E5 are pivotally connected at one end to the arms E3 and at the other end to the rods E2. A plate, E6,

is fastened to the rods E2 and extends between them. In the plate Ei are two pairs of rows of holes, g g' and h h. Pins t' t" are arranged in these holes. They ina-y be arranged in the holes g g or in the holes h h. They extend up to the ends of the shuttles El, and when the plate E6 is reciproeated backward and forward they cause the shuttles to move similarly through the races E. Vhen needles D10 are arranged on the front edge of the needle-bar, the pins t c" for actuating the corresponding shuttle are placed in the holes g g; but when needles are arranged on the rear edge of the needle-bar the pins for. actuating the corresponding shuttle are placed in the holes h h. I provide for shifting these pins z' iat pleasure to correspond to the positions which the needles may from time to time have. The holes g h occupy the same relation to each other as the notches in the edges of the needle-bar bear to each other. The relation of the holes l1. to the holes g is similar. The rock-shaft E4 is provided with an arm, e', which is connected bya rod, e2, with a crank-pin, e, extending from a disk,

'e2 aflixed to the shaft D6. y By these means the shaft Ds imparts motion to the shaft E4. Over the shuttle-races E is arranged a plate, E8. It is hinged at one end, and may be raised to facilitate access to the shuttles. A stitchplate, E9, having holes corresponding in position to the notches in the edges of the needle-bar, is arranged between the needles and the shuttles. It may be secured to the brackets E. The needles work through the holes lof this plate as usual.

IIO

presser-bar. These springs are coiled around Y the rods E', between pins extending from the rods and the upper parts of thebrackets B11.

I will now describe the mechanism for feeding the fabric or article to be quilted.

G designates a feed-bar having a number of rows of ratchetteeth, and moved upward, then forward, then downward, and then backward to the point of starting. ward and backward in an arc-shaped path, its greatest length of movement being opposite the place which is occupied by the longer edge of the fabric or article during quilting. The rows of ratchet-teeth may be formed integral with the feed-bar, or they may be made on separate plates fastened thereto. The feedbar G is secured to the forward ends of bars G. The bars G are hung on a shaft, G2, which is journaled in brackets G3, that a're affixed to the stationary main frame A. The shaft vG2 has merely arotary movement-in other words,

It moves forit has no longitudinal movement. On one end of the shaft G2 is a gear-wheel, Gt, which engages with a gear-wheel, G5, affixed to the shaft D5. The gear-wheel G5 is made so broad across its periphery that itwill not become disengaged from the gear-wheel G* during the longitudinal movement of the shaft D5. The bars G' are longitudinally slotted where the shaft G2 passes through them; hence, although they are supported at the 'rear end by said shaft, they are susceptible of a longitudinal movement independently of the shaft. On the bars G', in rear of the shaft G2, are laterally-extending studs G5, which preferably will be furnished with anti-friction rollers or bowls G'. rlhe studs pass through longitudinal slots in the bars G', and hence they may be adjusted into different positions lengthwise of the bars. When adjusted into position they may be clamped tightly to the bars by means of collars extending from them and bearing against one side of the bars, and nuts applied to the ends and impinging against the other side of the bars.

On the shaft G2 adjacent to one side of the bars G collars G8 are secured by means of setscrews or otherwise, and adjacent to the other side of the said bars eccentrics or cams Gg are similarly secured to the shaft. The cams G9 act on the rollers or bowls G5, and thus impart a backward movement to the bars G'. Springs G10, fastened to the bars G and to the brackets E', impel the bars forward whenever the position of the cams G2 is such as to permit of this. The bars G' are provided with downwardly-projecting pins G21, which prevent the bars from being moved too far forward by the springs G2. The manner in which the pins accomplish this is by coming in contact with the bars which are arranged at the top of the brackets E'. Owing to the use ofthe stop-pins Gu, the bars G do not move as far forward as they would be permitted to move by the cams G5. By setting the rollers or bowls G7 farther forward along the bars G', the backward movementwhich thebars G' willderivefromthe cams G9 may be made greater. The rollers or bowls G7 are so set that the bar G', which is connected to that end of the feed-bar G which is to feed the longer edge of the fabric or article to be quilted, will have the greater mot-ion. The difference between the positions of the rollers or bowls G7 should be such as to provide for the desired motion of the feed-bar G at both ends. The motion of the entire feed-bar G may be varied by adjusting the rollers or bowls G2; but in making an adjustment for this purpose care must loe taken to preserve the proper relative difference of motion between the ends of the feed-bar. A bar, G12, similar to the bars G', is shown as arranged between the latter. It will not, however, be necessary for this bar G22 to have any cam combined with it. 2' The bars G G12 derive an up and down motion from the cams or eccentrics H, arranged upon a shaft H. As here shown, these cams are made by cutting away portions of the said shaft. Separate cams or eccentrics may, however7 be attached to the shaft, if preferable. This ,shaft is journaled in the brackets G5, and has merely a rotary movement. 0n one end it has a gear-wheel, H2, which engages with the broad gear-wheel G5 of the shaft D, The gear-wheels G, G5, and

`H2 are shown as ofthe same size, and hence the shafts D5, G2, and H' rotate at the same speed. The up-and-down motions of the bars G GI2 are for the purpose of raising and lowering the feed-bar. Below the feed-bar G is a plate, I, fastened to the brackets E'. Above the feedbar is a plate, J, having slots through which the ratchet-teeth of the feed-bar rise to reach the fabric or article to be quilted. The plate J is shown as supported by a bar, J', fastened to the shuttle-races E.

K designates rollers, arranged over the ratchet-teeth of the feed-bar. These rollers are mounted on a shaft, K', supported at one end in a lever, K2, pivoted to one of the brackets G3, and at the other end in a lever, K, pivoted to a bar, K5, depending from the arm B8' The lever K4 slides along the shaft K as the carriage moves, but no longitudinal motion is imparted to the shaft. Springs K5, attached to the levers K2 Kt, force the rollers K down as far as they can go. When the feedbar is in its highest position, the rollers hold the fabric or article to be quilted down upon the ratchet-teeth of the feed-bar; but when the feed-bar descends the rollers hold -the fabric or article to be quilted stationary upon the plate J. rlhe rollers are loose on their shaft, and can move at different rates of speed.

W'hat I claim as my invention, and desire to secure by Letters Patent, is-

l. In a quilting-machine, the combination of a needle-bar, mechanism for reciprocating said needle-bar vertically, a feed-bar having a number of rows of teeth arranged thereon, mechanism for imparting motion to said feedbar through an arc-shaped path, and a number of freely-rotating presser-rollers arranged one above each of saidrows of teeth, substantially as specified.
