BEAD-FEEDING ATTACHMENT FOR EMBROIDERING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 392,893, dated November 13, 1888.

Application filed October 1, 1887. Serial No. 251.190. (No model.)

To all whom, it may concern.-

Beit known that we,GUsTAVUs E. STRAUSS, of the city, county, and State of New York, and JONATHAN B. WEST, of Rochester, in the county of Monroe, State of New York, have invented certain new and useful Improvements in Bead-Feeding Attachments for Embroidering-lllachines, of which the following is a specification.

Our invention has reference to a bead-feeding attachment for embroidering-machines of that class known as Swiss or Pantograph embroidering-machines, said feeding attachment being worked, whenever required, by a treadle located at the side of the treadles by which the needle-carriers are moved, so as to place aseries of bead-feeding tubes in line with the needles of the needle-carriers; and the invention consists of a bead-feeding attachment for embroidering-maehines,which comprises a feeding trough or hopper, a series of feedingtubes extending downward from said hopper, delivery-spouts at the lower ends of said-feed tubes, having slotted eyes in the front and rear walls, and recessed spring-jaws at both sides of said spouts for holding the beads in position for the needles to pass through, and mechanism for raising or lowering the bead-feeding attachment, so as to bring the beads into line with the needles of the needle-carriage whenever it is desired to supply beads to the needles.

The invention consists, further,of certain details of constructionsuch as the construction of the delivery-spouts with the bead-holding devices-as will be fully described hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of one end of an embroidering machine, showing the treadle mechanism by which our improved bead-feeding attachment is operated. Fig. 1 is a side view of the slotted slide-bar connected to the treadle for transmitting motion to the beadfeeding attachment. Fig. 1 is a detail top view of the bell-crank lever operated by the slide-bar for transmitting reciprocating motion to the slide-rod for operating the bead-feeding attachment. Fig. 2 isa vertical transverse section, drawn on a larger scale, of the bead-feeding attachment on line w at, Fig. 5. Fig. 3 is also a vertical transverse section of the said feeding attachment on line y 3 Fig. 4. Fig. at is a front elevation of the feeding attach ment,showing a number of tubes. Fig. 5 is a front elevation of the mechanism for imparting vertically-reciprocatingmotionto the beadfeeding attachment, the feed-trough and front plate being removed. Figs. 6, 7, 8, and 9 are details of the delivery-spout of the pearl-feeding tubes and the spring-jaws for holding the beads in position for the needles to pass through.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the supporting-frame ot a Swiss embroidering-machine of any approved construction; B, the

needle-carriage in front of the fabrics to be embroidered; O, the frame on which the fabrics are stretched; D, a hopper-shaped beadholding trough or receptacle, which is at-- tached to the front plate, I), said front plate, D, being guided by slots to on screw-studs a of fixed straps (L as shown in Figs. 3 and 4. From the perforated bottom of the bead-holding trough D extend in downward direction curved or inclined bead-feeding tubes E, which are provided with delivery-spouts E at the lower ends, said spouts being supported by brackets D that are attached to the front plate, D. The front plate, D, is provided at its rear part with pairs of anti-friction rollers d d, which turn on fixed pins d of the front plate, said pins being guided in slots d of a fixed plate, D, as shown clearly in Fig. 2. Between the anti-friction rollers (Z (Z is arranged a laterally-reciprocating slide-rod, F, which is provided at both sides of the feed-rollers d d, respectively above and below the rod F, with fixed ledges f, which are beveled at the ends nearest to the anti-friction rollers, so as to permit the easy riding of said rollers over said ledges whenever laterally-reciprocating motion is imparted to the slide-rod F. The end of the rod F is connected by an anti-friction roller with a slotted portion, f, at one end of a fulcrumed bell-crank lever, f, the other arm of which is engaged by an inclined cam-groove, of a vertically-guided slide-bar, f, that is operated by a treadle, F, which is arranged at the side of the treadles by which the needlecarriages of the embroidering-machine are operated. Bylowering the treadle the slide-bar f is pulled down, the bell-crank leverf is escillated, and thereby a lateral motion imparted to the slide-rod F, so that the lower ledge, f, on the same acts on the lower anti-friction roller (1 of the front plate, D, and causes the lowering of the bead-holding trough or receptacle 1), the feeding-tubes E, and the delivery-spoutEsufticiently to bring the lower ends of the deliveryspouts into line with the needles of the needle-carriage. By releasing the treadle the vertical slide-barf is raised again, the bell-crank lever f oscillated by the inclined slot f and the slide-rod F pushed back into its normal position, so that the bead-holding trough D, with its feedtubcs E and the delivery-spouts 'u, is raised by the action of the upper ledge,

f, on the upper anti-friction roller, d, as shown, respectively, in Figs. 2 and 5. In place ofthe slide-barf", bell-crank levers f and slide-rod F, any other mechanism by which motion is imparted to the bead-feeding attachment from the treadle F may be employed, as we do not confine ourselves to the special mechanism shown. It will thus be seen that whenever beads are to be supplied to the needles for beiug transferred by the same to the thread-forming stitches the bead-feeding devices have to be lowered to bring the needles in line with the beads in the delivery-spouts, so that they can take up in their forward motion a bead on each needle, upon which the bead-feeding devices are raised again, so as to clear the needles, while leaving beads on the same, which are then transmitted to the fabric in forming the stitches. I

The deliveryspouts E at the lower ends of the feed-tubes E are provided with slotted front and rear walls, the slots. h it having eyes h at the points where the needles pass through the spouts, as shown in Fig. 6. To both sides of each delivery-spout Eare applied, bysprings g, bead-holding jaws g, which are guided between the front and rear walls of the spout E and provided with semicircular recesses having grooved or depressed faces, as shown in Fig. 7, for holding the beads in line with the eyes h and the needles.

The jaws g are provided at the front and rear sides with flanges that fit into recesses g of the jaws, as shown clearly in Figs. 7 and 9.

When the entire bead-feeding attachment is lowered, so that the eyes of the delivery-spouts are in line with the needles, the latter pass in their forward motion through said eyes, the beads held by the spring-jaws being transferred to the needles by the upward motion of the feeding attachment by the action of the treadle F. During the upward motion of the spouts the spring-j aws are spread apart by the beads, as shown in Fig. 8, and clear the beads on the needles. While the jaws are spread apart another bead is fed to the center recess,

9 of each jaw, which recesses correspond to the shape of the beads and hold them in proper position, as shown in Fig. 7. another set of beads is ready to be fed to the needles for every stitch, as the delivery ofone set of beads also produces the dropping and downward feeding of the next set of beads to the recesses of the jaws, the downward feed taking place when the beads are taken up by the needles and the jaws spread asunder by the upward motion of the deliveryspouts, as shown in Fig. 8. The overlapping flanges of the jaws produce the proper guiding of the same, so that they supply the beads in a regular and reliable manner, and are returned into closed position when the beads have been delivered. The delivery-spouts and their springjaws form an essential feature of our invention, as by the same the beads are held in proper position, so that the regular delivery of the beads to the needles is secured. The vertically-reciprocating motion imparted by the treadle to the bead-holding trough, feed-tubes, and delivery-spouts shakes up the beads in the trough and feeds them at intervals through the holes in the bottom of the troughs to the tubes and from the same to the deliveryspouts, as indicated in dotted lines in Fig. 2, until all the beads are used, when a new supply is placed in the trough. In this manner the beads are regularly fed to the delivery-- spouts and transmitted from the same to the needles and the fabric, whenever a bead-stitch is desired to be produced. The attendant who operates the pantograph of the embroidering machine also operates the treadle by which the beads are delivered to the needles, whenever the pattern indicates that a bead-stitch is required, the lowering of the attachment bringing the beads in line with the needles, while the forward motion of the same and the rising of the feeding attachment deliver the beads to the needles which transfer them to the fabric to be embroidered.

Having thus described our invention we claim as new and desire to secure by Letters Patent 1. In an embroidering-machine, the combination, with a bead-holding trough, inclined bead-feeding tubes, and delivery-spouts at the lower ends of said tubes, said deliveryspouts having slotted eyes in their front and rear walls, of springs attached to opposite sides of said spouts, and jaws carried by said springs, said jaws having registering semicircular recesses with grooved faces within and between which the bodies of said beads are clasped to center them between said eyes, substantially as described.
