14 Claims. 1
My present invention relates to threading machines, and more particularly to a machine for threading beads, artificial pearls, and similar articles. g.
The, principal object of the present invention is to provide a machine which .will rapidly thread paratively-simple inconstruction and easyand v economical to manufacture andassemble.
.Another object of thevpresentinvention is to provide a bead stringing machine which. is simple and easy'to operate and does not. requirespecial skills. I
With-the above and tageous features in view, my invention consists of a novel arrangement of parts, more fully -disclosed in the detailed description following, in conjunction with .the accompanying drawings, and more particularly defined in the appended claims.
. In the drawings,

With the modern-style'trends in the jewelry industry and'thedevelopmentspf new and better methods. of manufacture, there :has been a great increase in thedemand for artificialor synthetic pearls. .These pearls can now be manufactured rapidlyand cheaply-in .quantity. .However, the threading .of these pearls on strings presents a problem which has. not.beensatisfactorily solved todate. .Thereare a few machin s manufactured which. thread beads. or pearls, but they are. com plicated and costly to build and they :areslow and have alimited capacity. 4
Most threadingis done by hand and this adds considerably to the final costof'the'necklace. .The
taken .on. line 2-2 other.v objects andv advanpresent invention provides a .simple machine which is easy and economical to manufacture and assemble and which has been found in actual use to thread beads or pearls so rapidly that it requires at least two operators toservice each machine. 7
Referring more in detailto the drawings illustrating my invention, Fig. 1 shows a complete machine embodying my invention. The :device ispreferably mounted on a base comprising'legs 29 connected by end bars 2! and a table top portion 22 extending across the-front of the base. I now provide a frame mounted on theend bases 2i .andcomprising vertical supports 23 extending from each end base 2 i 1 and connected at their upper ends by a horizontal support 24. The vertical support "23, totheleft in..-L Eig. l, is providedwith a clamp 25 supporting a reservoir 26 having a funnel bottom 21. The beads or artificial pearls 28 are put intothisreservoir and feed through the funnel'bottom 2'! into the trough 29. The trough 29.is generally v-shaped so that the beads or pearls will gravitate along the center, thereof. The trough '29..is-mounted on the vertical frame. members. 23 in the manner. shown in Fig. 4. An angle ,iron.30..-is bolted to the front of .each member 23 and supports .arubber plate or washer 3| upon which-anextended Portion 32 of the trough 2'9 rests. A bolt 33 extends through the angle iron, the rubber plate and the, portion 32 and holds the parts resiliently together by means of a coil spring 34' positioned beneath the head of the bolt. This arrangement holds. the trough firmly in place, :but .permits vibrating movement thereof as will-hereinafter be described.
The trough 29 is provided with av depending flange=35 extending along the .bottomrear wing of the trough as shown in Figs. 5 and 6. .It is also provided with a similardepending portion 36 along the front edge thereof. The flange portion 36 is provided along its front bottom. edge at spaced intervals with slots 31, seeFig. 4, which have wide front portions 38 and taper rearwardly towards the narrow slot portion 31. The bottom central portionofi the trough is provided with spaced openings 39, seeF-i v3, ofsufficient diameter to accommodate one head or pearl. Eachslot 31 is positioned in alignment with each opening 38 andcommunicating therewith. The trough is vibrated by meansof .a conventional vibrator ill, having depending arms, which is mounted on thejtop edgeofthe central part of the trough,-as shown in'Figs. 1-: and :2. The vibrator is operated from aswitch 4|- and-rheostat 42 mounted on the top horizontal supporting bar 24, as shown in Figs. 1 and 2. The pearls 28 thus feed into the trough 29 through the funnel 21 and the vibration of the trough causes the pearls or beads to move along the trough in a concentration towards the bottom central portion thereof, with said beads dropping into the openings 39, as will hereinafter be described.
The beads or pearls are initially threaded by the machine on needles 43, each opening 39 being provided with its own threading needle. Adjacent the bottom end of each vertical support 23 is mounted a bracket 44 supporting between them a rod 45. Each needle 43 is supported in an annular member 46 which is mounted on the rod 45, as shown in Figs. 1 and 5. The needle 43 extends into an opening 41 in the member 46 and is held in place by means of a thumb screw 48 extending through a cutaway portion 49 on the member 46. The member 46 can be held in any angular position on the rod45 by means of a thumb screw 56. When the needle is in upright position, as shown in Figs. 2 and 5, it will extend into the opening 39 in the trough 29, so that the upper end of the needle will be slightly below the level of the trough. In this position, as the trough is vibrated, the beads, bouncing along the trough, will be prevented from dropping into the openings 39 unless the thread opening of the individual bead is in alignment with the needle, in which case the head will slide through the opening 39 and on to the needle, as shown in Fig. 5.
In order to control the removal of the beads from the needle and the number of beads threaded to the needle, I have provided the lever linkage shown in Figs. 2, 5, 6, 9 and 10. Pivotally mounted beneath and rearwardly of the trough 29 behind each needle 43 is a stop lever 5|, Fig. 9. The lever 5| comprises an arm 52 having an upturned V-shaped front portion 53. Pivotally mounted below each stop lever 5| is an actuating lever 54, Fig. 10, which comprises a rearwardly extending arm 55 having spaced adjustment openings 56 and having a forwardly and downwardly integrally extending portion 51 with a V-shaped toe 58. This lever is mounted on a hub 59 having a forwardly extending lever 60 for manual operation. One of the adjustment openings 56 is linked to an opening 6| in the lever 5| by means of the link bar 62. The levers 54 are all mounted on a bar 63 extending between the vertical supports 23 and the movement of each lever may be regulated by a thumb screw or tappet screw 64 mounted in a supporting angle iron 65. Thus, the needle 43 can be properly centered under its opening by adjusting the screw 64. Also extending between the supports 23 to retain the levers in desired position, I use the spring 66 mounted on an angle iron 61 also extending between the supports 23.
In operation, the parts are positioned as shown in Figs. 2 and 5. In this position, the needles 43 extend vertically into the openings 39 and may be locked in this position by tightening the thumb screws 50.' The lever 54 is in its up position with the V-shaped toe portion 58 straddling the circumference of the needle spaced from the bottom end thereof and preventing the beads that may drop on to the needle from passing beyond the toes 58. It has been found that the beads or pearls will drop on to the needles with such speed that an operator is needed for each dozen needles. As soon as any needle has its full complement of beads or pearls, the lever 60 is pushed downwardly, as shown in Fig. 6. The initial movement of the lever 60 will swing the toes 58 away from the needle 43 into the dotted line position shown in Fig. 5 and permit the beads 26 to drop downwardly upon the needle and expose the upper end of the needle as shown in Fig. 5. Further movement of the lever through the bars 62 will swing the stop lever 5| upwardly, so that the V-shaped front portion 53 operates along the exposed portion of the needle into the bottom portion of the opening 39 and prevents any further beads from entering the openings. Th spring 66 will retain the levers in this position.
The thumb screw 56 is now loosened and the needle 43 pivoted forwardly towards the operator into the position shown in Fig. '7. The top of the needle is provided with a cutaway hook portion 68 into which a wire or cord can be hooked as shown in Fig. 8. The operative merely slides the beads off the needle 43 and on to the wire or thread 68. The wire or thread 69 is then unhooked and the needle pushed back through the slots 38 and 31 into vertical position and locked in such position bymeans of the thumb screw 50. The lever Iitl is now snapped upwardly against the action of the spring 66 and the parts are back in the position shown in Figs. 2 and 5, ready for another operation.
It is desirable that the needles have a tendency to remain in vertical position without looking. This can be accomplished by springs or by the arrangement shown in Figs. 1 and 2, wherein a cord 10. is attached to each member 46 and holding the weight ll. As can be seen in Fig. 2, when the needle is pulled downwardly, the cord will wind on the member 46 and the weight will tend to draw the needle vertically and hold it in vertical position. The use of thethumb screw 56 is therefore optional, as the cord 10 and weight 1 I will always tend to swing the needle into vertical position.
It can thus be readily seen that the device is simple in construction and easy and economical to manufacture and assemble. The assembly is so rapid that very few needles are required to keep an operator busy removing the beads on threads. It has been found that a row of 25 openings and needles will exhaust the quantity of beads travelling along the trough 29.'
Beads that are defective and cannot slide on to any needle will eventually work their way to the end of the trough, and an opening maybe provided for allowing them to drop into a discard receptacle. g I While I have described a specific embodiment of my invention, it is obvious that changes may readily be made in the size, shape or relative arrangement of parts without departing from the spirit and scope of the invention as defined in the appended claims.
