SPEOIFIGATION forming part of Letters Patent No. 467,138, dated January 12, 1892.

Application filed July 23, 1888.

To all whom, it may concern: 4 13c it known that I, CHARLES E. HADLEY, a cltlzen of the United States, and a resident of \Vashington city, in the District of Columbia, have invented certain new and useful Improvements in Quilting-Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the 1.0 letters and figures of reference marked there'- on, making a part of this specification.

The object of my invention is primarily to produce continuously-diagonal lines of quilting across the length of the fabric without reversing the feed of the goods under the needles or the movement of the needles over the goods, as in the machines now in use, and this object is attained by causing the needlebars and stitching mechanism in a quiltingmachine to revolve about a central axis while the fabric to be sewed is fed under the needies in a direction parallel with said axis and concentrically thereto.

My invention consists, broadly, in the or- 2 5 ganization in a sewing-machine of a complete stitch-forming mechanism of customary form made to revolve about a central axis, toward which the needles in said mechanism are made to reciprocate radially, in combination 0 with feed devices encircling the shaft at one end of the machine and which operate in unison with the movements of the needles to feed the fabric to be stitched concentrically in tubular form and in a direction parallel 3 5 with said axis between the needles and their shuttles and across the endless circular path over which they travel, all as hereinafter more fully described.

In the accompanying drawing, in which my revolving quilting-machine is illustrated in perspective, with portions of the fabric fed through it, A- represen ts a vertical shaft,which is stepped at its lower endin the foot-plate 1 of a standard 2, forming part of the outer support for the driving-gear, and is fixed at its upper end in a cross-bar. (Not shown in the drawing.)

in which a needle-bar 6 is suitably mounted parallel with the shaft A to reciprocate in the Serial No. 280,722. (No model.)

customary manner to and from it. This frame 5 supports also the mechanism for producing the radial reciprocation of thelneedle-bar to andfrom the shaft. The lower ring 3 is sup- 5 5 ported to revolve upon an annular horizontal bed or bearing-plate 7, encircling the shaft A concentrically, and which is supported by a bracket 8, projecting from the standard 2. The upper ring 4: rests and revolves in like manner upon a second annular plate 9, corresponding to the lower plate 7, and which is similarly supported to encircle the shaft A in a concentric manner by a radial arm projecting from the shaft, but which does not appear in the drawing. As the upper and lower rings 3 aud t are connected by the frame 5, they will revolve in unison. Their revolution and that of the frame carried thereby is effected by means of cogs upon the lower ring 3, which are engaged by a pinion 10 upon a vertical counter-shaft 11, geared to the main driving-shaft 12 of the machine. An interrupted worm 13, engaging a worm- Wheel 14, is interposed in the gearing by which the vertical counter-shaft 11 is connected to the main shaft 12, so as to produce an intermittent rotation of said counter-shaft, and consequently an intermittent revolution of the stitching mechanism about the central shaft. A long sleeve 15 is fitted upon the lower end of the fixed central shaft A to extend up nearly to the upper annular plate 9, and a cogged wheel 16 of, equal diameter and bearing the same number of teeth as the lower ring 3 is fixed to the lower end of said sleeve to gear with a pinion 17, corresponding with the pinion 10, and which is secured upon the same counter-shaft 11. Hence the sleeve 15 and the frame 5, carrying the stitch- 9o ing mechanism, will both revolve intermittently in the same direction and at the same speed about the central shaft A. The shuttle-box 18, in which the shuttles 20 are fitted to play in the customary manner under the needles carried by the needle-bar 6, is fixed by means of suitable radial arms 21 21 to the sleeve 15 to revolve with it, so that the proper relative position of the shuttle-carriers and needles is constantly maintained during their revolution about the common center. The necessary reciprocation of the needle-bar 6 is produced mediately during its revolution about the central shaft A by means of a concentric toothed ring 22 of a diameter slightly greater than that of the upper carrying-ring 4 of the frame 5. This driving-ring 22 is supported immediately above the ring 4 upon an interposed annular bearingplate 23, corresponding with the bearing-plate 9, and, like it, rigidly supported by a radial arm (not shown in the drawing) which projects fixedly from the central shaft A immediately above the arms supporting said plate 9. A series of cogs formed upon the periphery of the ring 22 engage a pinion 24 upon the end of a counter-shaft 25, mounted in the frame 5 parallel with the needle-bar, and this pinion 2i serves, byineans of an eccentric and link 26, to oscillate a rock-shaft 27, to which the needle-bar (5 is coupled, so as to be actuated thereby in the customary manner, and which need not herein be more fully described. The driving-ring 2 is preferably made to revolve independently of the revolution of the frame 5 and in the opposite direction by means of beveled teeth 28 on its upper edge, which engage a beveled pinion 29 on the end of the main shaft 12 of the machine.

In order to insure the proper synchronism in the movements of the shuttles and needle-bar 6, the shuttles are actuated by a rockinglever 30, pivoted upon the sleeve 15, and which is actuated by an eccentric 31 upon a vertical counter-shaft 32, supported inabearing 33, fixed to and carried by the sleeve 15, said counter-shaft 32 being geared to a toothed wheel 34, revolving loosely upon the sleeve 15, and which by means of a bevel-gear 35 is driven from a counter-shaft 36, supported by the standard 2, parallel with the main shaft 12, to which it is properly geared so as to rotate in unison therewith. The fabric 60 to be quilted is passed up longitudinally inside of the lower ring 3, so as to encircle the eentral shaft A in a tubular form more or less complete, and is carried between the needles and the shuttles under a suitable throat-plate 37, carried by the frame 5, and over an underlying plate 38, carried by the shuttle-box 18, and up inside the annular plates 9 and 23 and the rings revolving thereon, so as to pass out above the same.

The feed device by which the cloth is drawn forward or upward between each stitch consists of two pairs of concentric rings 41 atl and 42 42, mounted upon the shaft A above an annular plate 40, encircling the shaft concentrically immediately above the driving-rin g 22, andwhichissupported upon an arm 39,extend ing from the outer frame carrying the main and counter shafts. The two rings in each pair are connected by a single radial arm 43, and each is supported upon the ends of a series of radial levers 5O 50, pivoted, the one set for the lower ring, to a long sleeve ll, sliding longitudinally upon the shaft A, and the other, for the upper ring, to an outerconcentric sleeve 45, sliding frcely' upon the sleeve l t. The outer ends of the lovers are pivoted to loose plates 51 51, curved to fit against the fabric, while the latter bears upon the inner face of the outer ring, the inner ring being slotted, as shown at 49 49, to allow of a connection between said levers and plates, and the levers are all fitted to incline upwardly from the central shaft outwardly, so as to operate as toggles when the sleeve to which theyare attached is lifted, and thereby cause the curved plates to clamp the fabric between'them and the outer ring. The inner sleeve ll is made long enough to engage, by means of a pin projecting laterally and radially from its upper end, acam-groove 46 in the face of a cam-wheel 48, mounted to rotate in proximity thereto upon a counter-shaft (not shown in the drawing) suitably geared to a shaft 55, rotating parallel with the main shaft of the machine to which it is mediately geared, as shown in the drawing, while the length of the outer sleeve 45 adapts it to permit a pin projecting radially therefrom to engage the lower portion of the same cam-' groove 46. The cam-groove 46 is so shaped that the two sleeves 44: and 4.5 are alternately raised and lowered in the revolution of the cam-wheel 48. As either sleeve is lifted its toggle-levers 5O 50 are brought into play to cause the elamp-plates 5151 to close upon the cloth within the rings -11 41, so that the cloth shall be drawn upward with the rings, and as they descend the toggles are loosened so that the rings may slide freely over the fabric. As one set of toggles tighten and are as cending the other set are loosened and dcscend, so that a constant intermittent feed of the cloth is produced thereby in a direction parallel with the central spindle A, about which the needles and their shuttles in the meantime revolve at a right angle to the feed of the cloth, producing as a result diagonal lines of stitches across the face thereof.
