IVIECHANISM FOR SEWING ON BEADS.
SPECIFICATION forming part of Letters Patent No. 271,473, dated January 30, 1883,
Application tiled June 24, 18872. (No model.)
To all whom it may concern Beit known that l, THOMAS K. KEITH, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain Inlprovements in Sewing-Machines, of which the following is a specification.
This invention has for its object to provide feeding mechanism whereby a string of beads may be secured to the side of a piece of cloth or other material for ornamentation.
The invention consists, as a whole, in the im1 proved mechanism hereinafter described,com
prising a feed-dog and presser-foot, adapted ,to enter the space between two beads' on a cord or wire, and thus engage itself with the beads, and mechanism for moving the material laterally to cause the needle to enter the material alternately at opposite sides ofthe liueofbeads, and progressively to give theeproper feed movement to the material, all of which I will now proceed to describe and claim.
' Ot' the accompanying drawings, forming a part of this specification, Figure l represents an end elevation of the arm and a portion of the bed of a sewing-machine provided with my improvements. lion ofthe same. Fig. 3 represents a section on line a', Fig. 2, looking toward the outer end ot' the arm. Figi represents-a section on line y y, Fig. 2. l
The same letters of reference indicate the same parts in allthe gures.
In the drawings, A represents the bed, B the needlebar, and O the presser-bar, of an ordinary sewing-machine. The usual feed-dog and presser-foot are omitted, and in lieu thereof a single device, D, which performs the functions of both, is employed. This device is composed ot' a lever pivoted at E to the arm G' of the presser-bar, so as to be capable of rocking or oscillating in the direction in which the work is fed in a sewing-machine, and curved downwardly to a point in front of the needle, where it terminates in a wedge-shaped edgeorpoint,D,whichIcallthefeedpresser.77 Said feed-presser is adapted to insert itself between two cfa row of beads on a string or Wire, and is provided with a notch, F, adapted to bestride the string or wire on which the beads are strung. The presser-bar is cylindrical, and is adapted to turn or work in its bear- Fig. 2 represents a rear eleva.
ings, and thus oscillate the feed-presser in a direction which is transverse to thelinein which the work is usually fed in a sewing-machine.
The beads to be secured to a piece of material, H`such as a partl of a shoe upper or other article-are closely strung upon a ine wire, I. The string of beads being attached at one end of the material, it will be seen that the insertion of the feed-presser D' between 60 I the beads wit-li the notch F bestriding the wire enables said presser to move the work laterally, so as to place the row of beads rst at one side of the needle and then at the other side, thus causing the stitches to be formed across the string ot' beads, and to push or feed the work progressively as fast as the beads are secured.
The mechanism for operatic g the feed-presser to effect the described movements may be variousiy modified, and I do not limit myself to the particular form shown. The mechanism shown in the drawings and hereinafter described is the best for accomplishing the desired purpose that I am at present aware of.
An arbor, J, is journaled in bearings attached to the arm K of the sewing-machine, and to said arbor are attached a ratchet, O, and a series of cams, L M N. Said ratchet and cams are rotated intermittently bya pawl, 8g P, engaging with the ratchet and pivoted to a lever, Q, which is pivoted to a\stud, S, on the arm K, and is drawn backwardly by a spring,
R, against the arm K.
Therock-shaft T, that operates the needle-bar 8 5 in the usual manner, is provided with an arm,
U, having a friction-roller which bears against the lever Q, and when the shaft T is rocked alternately forces outward and releases the lever Q, thus causing the pawl P to rotate the 9o ratchet O and the cams connected therewith step by step.
The cams L, M, and N bear respectivelyv against levers L', M', and N', which are piv-v oted at V to the arm K, and' are displaced or 95 rocked on their pivot by the rotation of the cams. The lever L' is pressed by a spring, W, against the cam L, and is extended downwardly to the ,lever D, where itis provided witha pin, a, entering a diagonal slot, I), in loo the lever D. In consequence of the diagonal slot and pin the rocking motion of the lever L',
induced by the cam L and spring YV, causes the lever D to oscillate in a vertical plane and moves the feed -presser Dl in the direction in which the work is fed by the usual feeding devices of'a sewing-machine. rlhe lever M bears against an arm, d, rigidly attached to the presser-bar C. A spring, 1, extending from the arm d to a stud, on the arm K, holds the arm d with a yielding pressure against the lever M', and the latterI against the cam M, which cam is shaped as shown in Fig. Ll, the projections shown thereon coniprising one-halt' of its periphery. \Vhen the lever M' is moved backwardly by a projection ofthe cani M, said lever, through the arm d, turns the presser-bar C in its bearings, and thus lnoves the feedpresser in a direction transverse to the direction ofthe feed movement, so as to move the line of beads from one side ot' the needle to the other. When the lever M is moved forward into a recess in the cam M by the spring e the feed-presser is moved in the opposite direction, so as to carry the beads to the other side ofthe needle.
The lever N has an arm, y, which extends backwardly and bears against the-crank or arm l1, wherewith the operator raises the presserbar O in ordinary sewing-unichines, said crank being attached, as usual, to a shaft,,journaled in the arm K, and provided with a cam, j, which bears against a stud, l, on the presserbar and raises the latter against the pressure of its springm when lthe shaftt' is turned. rlhe downward pressure of the pressure-bar spring m acts, through the cam j, shaft t', and crank h, to press the lever N against the cam N. The rotation ofthe said cam rl causes the lever N to alternately raise and release the presser.
The parts thus described are so timed and arranged that their joint operation is as follows: The string of beads being attached at one end to the material ll, the beads are placed under the feed-presser, so that the notch F will bestride the wire. \Vhile the needle is descending, and before it enters the work, the feed-presser is stationary and holds the beads so that the needle will pass close to one side of them. \\vhen the needle is in the work the leed-presser is raised by the cam N, moved forward toward the front ol' the machine by the spring \V, and depressed by the presserbar spring nl, and thus caused to enter the space behind another bead. \Vhcn the needle rises and leaves the work the feed-presser is moved away from the front ot' the machine by the cam L, thus giving the work the required feed movement, and then laterally by the cam M or the sgi-ing 0, as the case may be, thus moving the line ot' beads so that the needle in its next descent will pass through the work at the opposite side ot' the beads. rlhe operation is thus repeated, the feed-presser being raised, moved toward the front, and
dropped upon the beads during each descent of the needle and moved backward and laterally with the work after each ascent ot' the needle. The beads are thus rapidly and securely attached to the material. The limited bearing ofthe feed-presser upon the work enables the operator to turn the work as may be desired, to arrange the string ot' beads in loops, curved lines, and other fanciful designs. rlhe feed-presser is shown in Fig. 2 as being composed of the points ot' two levers, 2 3, the notch F being the space between the points of said levers. In this instance both levers are operated simultaneously by the cam Land lever' L; but it is obvious that an additional cam may be employed to operate one. ot' the levers 2 3 independently ot' the other, so that said levers may alternate in giving the string of beads its feed movement.
The levers L M' N may be made adjustable as to the length of their throw by adjustable faces bearing against the cams L M N.
l claim- 1. ln a sewing machine, a feed-presser formed substantially as described, to engage with a string` ot' beads, combined with mechanism operated by the power ot' the machine, for giving said feed-presser the described movements, whereby the string of beads and the material to which they are attached are moved both longitudinally and laterally, as set forth.
2. In a sewing-nmchine, the combination of the feed-presser pivoted, as described, to the presser-bar, and adapted to engage with a string` ot' beads, a. series of cams rotated intermittently by the power of the machine, and intermediate devices, snbstantiallyas described, whereby said cams are caused to operate the feed-presser vertically, longitudinally, and laterally. in the manner set forth.
3. The combination ot' the lever D, having the feed-presser, and pivoted to the presser'- bar, and means, substantially as described, for oscillating` said lever in a vertical plane, as set forth.
LL. The combination ot' the lever' D, having the feed-presser, the presser-bar U, supporting the lever D, and means, substantially as described, for rocking the presser-bar and lever D horizontally, as set forth.
5. The combination of the lever D, having the feed-presser, the presser-bar C, supporting the lever D, and means, substantially as described, for automatically raising or releasing said presser-bar and lever', as set l'orth.
1n testimony whereof l have signed my name to this specilication, in the presence of two subscribin-g witnesses, this 19th day ot' June, 1882.
