SEMIAUTOMATIC' ORNAMENT GLUING MACHINE Filed Aug. 31, 1 960 4 Sheets-Sheet 4 INVENTOR. MORRIS KORTICK ATTOR Y United States Patent 3,149,972 SEMI-AUTOMATIC ORNAMENT GLUING MACHINE Morris Kortick, Cranston, R.I. (166 Valley St., Providence, R.l.), assignor of one-half to Louis Yanolf, Providence, RI.

Filed Aug. 31, 1960, Ser. No. 53,089 31 Claims. (Cl. 156--566) My present invention relates to the jewelry art and more particularly to a semi-automatic machine for gluing ornamental stones such as rhinestones into prepared settings.

The principal object of the present invention is to provide a semi-automatic machine for eliminating most of the manual labor heretofore required in gluing ornaments on articles of jewelry.

Another object of the present invention is to provide a semi-automatic gluing machine which materially speeds the gluing operation by preparing the ornament or stone and the glue prior to assembly with the article.

A further object of the present invention is to provide a semi-automatic machine which will glue the rhinestones into position without spreading excess glue on to the article of jewelry and thus saving a cleaning operation.

Another object of the present invention is to provide a semi-automatic gluing machine which is simple in construction and operation and readily adaptable to many variations including multiple assemblies.

With the above and other objects and advantageous 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,

FIG. 1 is a plan view of the operating portion of the machine embodying my invention.

FIG. 2 is a side elevation thereof.

FIG. 3 is a plan view, partially diagrammatic and partially broken away of the operating portion and the control and drive portions.

FIG. 4 is an enlarged section on line 4-4 on FIG. 3.

FIG. 5 is a front elevation, partially in section of the operating portion.

Jewelry ornaments such as rhinestones are held in stamped settings with prongs that are bent over in a manner similar to the settings of real diamonds. However, a great deal of the costume and other types of ornaments are cast. In such constructions a tapered opening is cast for each rhinestone which must be glued into the opening. For a great many years this gluing operation has been performed manually. The operator deposits a measured drop of glue into the opening, picks up the rhinestone with a pair of tweezers right side up and deposits the rhinestone into the opening. Many of the pins and brooches and other ornaments require 15 or 20 stones to each piece. It can well be appreciated that the manual assembly is slow and costly. Where a great deal of production is required hundreds of girls are sometimes hired for the sole purpose of gluing rhinestones into pieces of costume jewelry.

The present invention provides a machine which eliminates most of the slow laborious labor required in the gluing operation, removes the guesswork from the amount of glue to be placed in the opening and provides for a much more rapid and cleaner operation. The machine of the present invention is only semi-automatic because it still requires that the operator hold the article of jewelry in position for the setting of the stone. However, it can easily be rendered completely automatic if there is to be a large volume of any one particular design.

3,140,972 Patented July 14, 1964 This feature will be apparent after the description of the operation of the machine. Also, the machine has been illustrated for gluing one rhinestone at a time. This is for illustrative purposes only. The machine can readily be adapted to glue a multiplicity of stones simultaneously.

In handling rhinestones one of the most difficult problems is the positioning of the tiny stone in right side up position for proper feeding. The present invention utilizes the hopper feed principle shown in my copending application entitled Automatic Ornament Setting Machine, Serial No. 845,204, filed October 8, 1959, and in my copending application entitled Automatic Finding Assembly Machine, Serial No. 43,783, filed July 19, 1960, now Patent No. 3,099,068. These applications utilize a rotating plate having openings which hold a rhinestone in one position only. This plate is made the bottom of a hopper holding a large number of stones. Thus the rotating plate always presents a stone in right side up position to an operating head.

Referring more in detail to the drawings, the machine of the present invention is mounted on a rectangular base 10 with the stone handling and operating portion mounted at the front of the base 10 as shown in FIG. 3 and the control and drive portions mounted to the rear of the base 10. The stone handling and operating portion includes the hopper and hopper drive illustrated in FIGS. 1, 2, 3 and 4. The hopper comprises a plate 11 having a plurality of stone holding openings 12 extending adjacent the circumference thereof. The plate is rotatably mounted on a pivot post 13 which is mounted in the base 10, see FIG. 4. The hopper wall comprises a cylindrical member 14 which slides over the plate and rests on the base. The hopper wall is provided with a plurality of spaced radial wall portions 15 having brushes 16 at their bottom edges contacting the upper surface of the plate 11 for properly positioning the rhinestones in the openings 12 in the manner more fully disclosed in my copending applications above referred to. Viewing FIG. 1, the upper right hand quarter of the cylinder 14 is provided with a lower portion 17 which permits movements of the carrying arm hereinafter to be described. Adjacent the portion 17 is a gap 18 which permits entry of the pickup head hereinafter to be described.

Rotation of the plate 11 is clockwise and is provided by the mechanism mounted beneath the plate and shown in FIGS. 3 and 4. A ratchet wheel 19 is mounted on the pivot pin 13 and is provided with a centering opening 20. The plate 11 is provided with 21 depending pin 21 which enters the opening 20 to ensure the alignment of one of the stone holding openings 12 with the movement of the pickup head through the gap 18. Beneath the ratchet wheel 19 is a rectangular block 22 also pivoted on the pin 13. Viewing FIG. 3, the lower end of the block is provided with a pawl 23 pivotally mounted on the block 22 and having a tapered finger 24 which engages the peripheral teeth of the ratchet wheel 19. The pawl is held in yielding engagement with the ratchet wheel by the spring 25, FIG. 4. The opposite end of the block 22 is provided with an extended arm 26 to which the operating arm 27 is pivotally attached. When the arm 27 is reciprocated it will force the block 22 to pivot back and forth around the pivot pin 13. This will cause the pawl 23 to move the ratchet wheel in a clockwise direction carrying the plate 11 with it. A small block 28 is fastened to the base 10 forwardly of the pawl 23 to act as a stop, so that the block 22 will move in a clockwise direction only so far and no further. This motion is equivalent to the movement of three of the stone openings 12 on the plate 11. The plate 11 is provided with a number of openings which will not divide by three. For example 56 openings may be provided. This means that each opening must make three revolutions before it is again positioned in alignment with the pickup head. This ensures that when the opening is thus aligned a stone will be positioned therein in right side up position and the machine will not miss.

Moving clockwise around the ratchet wheel 19 and just beyond the stop member 28 is a block 25 secured to the base 10 and beneath the plate 11 on which a pawl 30 is pivoted, the pawl 36 also engaging the teeth on the ratchet wheel 19. This pawl 30 is a stop element which prevents rearward movement on the ratchet wheel 19 when the pawl 23 is being swung counterclockwise. On the other side of the wheel 19 is a second stop block 31 which is generally L-shaped and pivotally mounted on the base 10. The second stop block is provided with a portion 32 which is in the path of forward motion of the block 22. When the block 22 is feeding it engages the portion 32 and pivots it until the other end 33 clamps on to the teeth on the ratchet wheel. At high speed this prevents overriding and ensures the stopping of the plate 11 in alignment with the pickup head.

The glue dispenser is mounted forwardly of the hopper feed as shown in FIGS. 1, 2, 3 and 5. The base 10 is provided with a short forwardly extending portion 34 having a transverse dovetail groove 35. A block 36 is slidably mounted in the groove and locked in place by a suitable set screw (not shown). As can be seen in FIG. 5, the block 36 is pushed in from the right of the portion 34 until it abuts the solid end of the groove to the left to properly position the gluing dispenser. The block 36 constitutes a glue reservoir 37. The container of glue 38 is inverted to the right as shown in FIG. so that the glue enters the reservoir 37 and fills the portion to the left. The portion to the left is provided with a cover 39 having an opening or slot 40. A shaft 41 extends through the block 36 adjacent the upper edge as shown in FIGS. 1 and 5. The outer end of the shaft is provided with an arm 42 extending at right angles thereto to which a detachable operating arm 43 is attached. The operating arm 43 runs parallel to the arm 27 as shown in FIG. 3, and at the rear end thereof is connected by a transverse bar 44 to a piston rod 45 which operates the arm 27. The piston rod 45 is connected to a piston that is slidably mounted in a fluid cylinder 46. With this construction the arms 27 and 43 operate simultaneously. Reciprocation of the arm 43 will cause a oscillating movement of the shaft 41. Adjacent the other end of the shaft 41, is a dipper 47 having a conical opening 48. The opening 48 is of the same angle and shape as the bottom of a rhinestone. However, the depth of the opening 48 is equal to one half of the height of the bottom portion of a rhinestone. As shown in FIG. 2 when the arm 43 moves forwardly to rotate the shaft 41 the dipper 47 moves through an angle of 90 degrees into the glue reservoir 37. When the arm 43 moves in the opposite direction the shaft 41 is rotated in the opposite direction and the dipper 47 turns upwardly with the opening 48 filled with glue. The glue level in the reservoir 37 is maintained from the bottle 38. If the glue is extremely heavy it can be force fed by putting an opening in the top of the bottle as viewed in FIG. 5 and forcing air into the bottle. Various devices for ensuring a proper flow of glue from this type of dispenser can be used. An auxiliary sliding cover 49 may be positioned on the cover 39 for closing the reservoir slot 40 when the machine is not in use to prevent the glue from drying out.

The pickup on the rhinestones is provided by the construction shown to the right in FIG. 1 and is also illustrated in FIGS. 2, 3 and 5. A cylinder 50 is provided with an operating piston rod 51 which is attached at right angles to the bottom of a vertical bar 52. The upper end of the bar 52 is bolted to the end of an elongated operating arm 53. Mounted on the base is a post 54 which comprises at its upper end spaced bearing arms 55. The operating arm 53 slides between the arms 55. A

fixed shaft 56 extends transversely between the arms 55 so that the bottom of the arm 53 rides on the shaft 56 as shown in FIGS. 2 and 5. With this arrangement reciprocation of the piston rod 51 will cause reciprocation of the bar 53 on the shaft 56. The bottom edge of the arm 53 is provided with a transverse V-shaped groove 57 adjacent its rear end. A second transverse V-shaped groove 58 is positioned intermediate the ends and a third V- shaped groove 59, slightly deeper than the grooves 57 and 58 is positioned towards the front end. When the bar 53 is reciprocated there will be a drop at each groove in both forward and backward movements. However, in back of the central groove 58 is a slot 60 in which a small block 61 is pivotally mounted under the tension of the spring 62. As can be seen in FIG. 2 when the bar 53 is reciprocated rearwardly the block 61 will fill the groove 58 and allow it to ride over the shaft 56 without dropping. However, on the forward movement the block 61 will be kicked rearwardly and will allow the shaft 56 to enter the groove 58. Since the device operates at extremely high speeds and the groove 58 is not required during the rearward movement of the arm 53, the above construction reduces unnecessary noise, vibration and wear at this point.

Mounted at the forward end of the arm 53 and at right angles thereto is a block 63. The free end of the block 63 is provided with a depending block 64 having a vertical opening therethrough as shown in FIG. 5. A hollow pickup cylinder 65 is slidably mounted in the opening in the block 64. The lower end of the cylinder 65 is tapered at 66. The upper end is provided with a collar 67 which rides in a wider portion of the vertical opening and forms a stop for the lowermost position of the cylinder 65. The upper end of the cylinder 65 bears against a spring pin 68 which operates an electrical switch 69 connected by wires 70 to the hookup shown to the left in FIG. 3. The block 63 is provided with an L-shaped passageway 71, the vertical leg of which is connected by a flexible hose 72 to the control mechanism shown to the left in FIG. 3. The horizontal leg of the passageway 71 communicates with the interior of the cylinder 65 through a passageway 73 in the block 64 and an opening 74 in the cylinder 65.

The actual gluing operation takes place as follows:

The bar 53 moves rearwardly carrying the head with the cylinder 65 through the gap 18 in the hopper 14. Simultaneously the rods 27 and 43 move forwardly so that the plate 11 is rotated three spaces and the dipper 47 is submerged in the glue. When the arm 53 is pulled rearwardly until the groove 59 rides over the shaft 56 it will drop downwardly sufiiciently for the bottom end of the cylinder 65 to contact a rhinestone in the plate 11. A vacuum pressure is flowing through the cylinder 65 by way of the various passageways and the flexible hose 72. As the cylinder 65 picks up the stone by vacuum pressure it moves forwardly and is lifted out of the groove 59 to raise the stone sufliciently to clear its opening 12 and be carried forward. During this forward motion the rods 27 and 43 are moving rearwardly and the dipper 47 is moving upwardly to the position shown in FIG. 2 with the cavity 48 loaded with glue. As the groove 58 reaches the shaft 56 the bar 53 again drops to dip the stone into the cavity 48. The distances are such that the stone will enter the cavity approximately .020 inch from the bottom. The glue will surround the lower half of the rhinestone and any excess or overflow will squirt over the sides of the dipper leaving the top of the stone clean. The arm 53 then carries forwardly into the final forward position shown in FIG. 2 with the shaft 56 in the groove 57. The operator holds a piece of jewelry with one of the settings directly under the rhinestone and moves it upwardly so that the rhinestone enters the setting and is glued therein. The moment the operator touches the rhinestone the cylinder 67 is pushed upwardly against the pin 68 and trips the electrical switch 69. This changes the vacuum pressure to a blowing action for a split second to clear the passageway in the cylinder 65 and also immediately and rapidly pulls the arm 53 rearwardly for a new cycle. Note that because of the groove 57 the initial rearward movement of the arm 53 will lift the arm and the front end so that the cylinder 65 is lifted from the manually held article of jewelry as it is pulled away from it. This prevents snagging or interference with raised portions of the jewelry. The device is now ready for another cycle and the gluing of another rhinestone. The action is so rapid that when the operator picks up one rhinestone and turns the article of jewelry to the next cavity, the head is actually in forward position and ready with another glued rhinestone.

The entire action as hereinabove set forth is controlled by the electrical and pneumatic arrangement shown to the left in FIG. 3. Referring to FIG. 3, the electrical portion of the control comprises the source of power 75 controlled by a master switch 76. The source of power is controlled by the switch 69 shown diagrammatically as being in the line 70 but actually positioned in the operating head as shown in FIG. 5. The switch 69 sends current to a solenoid valve 77 and a solenoid valve 78 and to a counter 79 which counts the number of stones.

The pneumatic system is shown in heavy black lines and comprises a vacuum line 80 which leads to the solenoid valve 78, another line 72 from the solenoid valve 78 to the operating head 63. The air pressure line 81 leads to a bleeder valve 52 which is connected at one end by a line 83 to the solenoid valve 77. The valve 8?. is also connected by a line 84 to the front end of the cylinder 46 and the rear end of the cylinder 58. Another line 85 is connected to the rear end of the cylinder 46 and the front end of the cylinder 56. The bleeder valve is controlled by a line 86 extending to an operating button 8-7 posi tioned in the path of rearward movement of the vertical bar 52. The relation of the operating portion to the operation of the device as above described may now be described as follows:

The operators contact withthe rhinestone closes the switch 69. The resultant current opens solenoid valve 77 to exhaust which bleeds air and exhausts it from the back of cylinder 50 and the front of cylinder 46. Simultaneously solenoid valve 7 8 switches from vacuum pressure to blowing pressure through line 72. There is a slight hesitation as the pressure drops and then the piston in the cylinder 50 moves rearwardly and the piston in the cylinder 46 moves forwardly both under positive air pressure. The pickup head is thus moving rearwardly as the plate is being turned and the dipper drops into the glue. When the arm 53 reaches its rearward movement so that the groove 59 drops over the shaft 56 the cylinder 65 picks up another rhinestone. Note that as soon as the operator has picked up the first rhinestone and removed the pressure from the cylinder 65, the switch 69 is again opened and the solenoid valve 78 is again applying a vacuum pressure to the head through the hose 72. At the rearmost point of the arm 53 the bar 52 hits the button 87 which operates the bleeder valve 82 to bleed the pressure from the back of the cylinder 46 and the front of the cylinder 50 and reversing the direction of movement to complete the cycle.

The operation of the device is extremely rapid there being only a slight hesitation at the end of the rearward movement sufiicient to allow the cylinder 65 to pick up a rhinestone from the plate 11. At the end of the forward movement the device will stop until the operator reverses the action by picking off the rhinestone and tripping the switch 69. The device thus applies a proper amount of glue to the bottom portion of each rhinestone so that the operator can position the rhinestone in its prepared opening without spreading excess glue over the rhinestone or over the article of jewelry.

The device has been illustrated with a single cylinder 65 picking up a single rhinestone. However, where production warrants the cylinder 65 can comprise a multiple head designed to pick up a plurality of rhinestones in the manner shown in my copending application Serial No. 43,783 above referred to. The gluing dipper can be provided with a multiplicity of openings and an entire finding can thus be loaded simultaneously with a plurality of stones. If desired the device can also be equipped with the type of feed mechanism shown in my copending application so that the findings can be automatically fed beneath the operating head thus rendering the device completely automatic. These additions are economically sound only where large quantities of a single design are to be run.

The device is purely illustrative in many respects. The gluing arrangement may readily be changed. For example, the rhinestone can be dipped directly into the glue reservoir by raising the reservoir. This would require a more careful maintenance of the level of the glue in the reservoir. The operating portions, using compressed air cylinders can also be changed to a completely electrical system using reversing motors. Other variations will be readily apparent to a person skilled in the art.
