SPLIT RING ASSEMBLY MACHINE FIELD OF INVENTION The present invention relates to an assembly machine and more particularly to a machine operable to open rings of the spiralled wire split" ring type to link together the component assemblies of jewelry, fishing lures and the like to provide a linkage between said component assemblies.

DESCRIPTION OF THE PRIOR ART Split" rings as used in the present disclosure relates to rings commonly used to hold a multiplicity of keys together which is usually made by compressing together a spring steel spiral to form the ring. As commonly used, an article having an eyelet, such as a key, is caused to be inserted over one of the terminal ends of the ring spiral that has been sharpened to a point and then to twist the ring through the eyelet until the article such as a key is held within the spiralled ring. Formerly assemblies of such rings to articles to be linked together has been accomplished by the hand operation as aforesaid, and, therefore, split rings could not economically be used in commercial high-speed production. Instead, rings made from a single strand of wire having its terminal ends abutted together have more generally been used to assemble components and accessories to be linked together. Opposing forces exerted on the components or accessories so linked together tend to cause such a link to pull apart. Therefore, it is more desirable to use the split ring for the reason that inadvertent disassembly may not likely occur.

Accordingly it is a very important object to the present invention to provide a machine which may quickly and economically link components and accessories together on a split ring link, and to provide a machine which is simple in its construction and operation. A further object of this invention is to provide in a split-ring assembly machine the combination of means to feed split rings into the operating apparatus, means for placing split rings on a pedestal to be held into position and means for opening the split-ring for fast and easy assembly of accessories and components thereto.

These and further objects shall become more clearly apparent from the description of the preferred embodiment hereinafter set out, particularly when understood with connection with the drawings forming a part of this specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings the split" ring assembly machine of the present invention is shown to advantage in FIG. 1 and is generally designated by the numeral 10. A commonly known vibratory hopper 11 is provided on the machine housing 12. The hopper 11 includes a spiralled track 13 issuing out of a flat bottom pan portion 14. As the hopper I1 is caused to vibrate, split" rings (not shown) in the hopper 11 are caused to be oriented horizontally on the pan l4 and on the track I3, and to be advanced counterclockwise on the spiralled track 13 in response to the rotational movement of an eccentric vibrating motor commonly known and forming an integral part of the hopper l1. Toward the upper terminal end of the track 13, the split" rings tend to be inclined upwardly by the side of track being more steeply inclined.

A split ring feed mechanism 15 is provided on the housing 12, having one of its terminal ends suitably fastened to the housing adjacent an outlet opening 16 of the hopper 11 provided at the terminal end of the track 13. The feed mechanism 15 is inclined downwardly from the hopper II on the housing 12 and is cantilevered over the housing at the terminal end opposite the hopper. The feed mechanism 15 is operable to cause "split" rings received from the hopper 11 to be fed through the mechanism by gravity as hereinafter later described. The feed mechanism 15 comprises a horizontally disposed bed portion 17, a pair of parallel, upstanding guide members 18 and I9 suitably fastened to bed 17 and spaced apart to provide a trough in which the split" rings may travel downwardly in the feed mechanism 15; a split" ring retaining-release assembly 20; and a stop portion 21. The bed 17 is provided with a split" ring exitway 22 at the terminal end opposite the end thereof adjacent the hopper outlet opening 16.

FIGS. 2 and 3 show to advantage the detailed construction of feed mechanism 15. The components thereof identified above are identically numbered in each of the drawings. The split" ring retaining-release assembly 20 is pivotally mounted to and carried by the underportion of the bed 17 and is disposed between the bed 17 and a mounting block 23 provided on the housing 12 to carry feed mechanism 15. The retaining-release assembly 20 comprises a U-shaped body portion 24 issuing upwardly at more or less, to a stop mounting block portion 25, the stop-mounting block portion 25 having a knifelike split ring stop-release blade 26 suitably fastened to one of the faces thereof; and a retaining studmounting block 27 slidably mounted on the body portion 24 on the side opposite the stop-mounting block portion 25. The retaining stud-mounting block 27 is provided with a retaining stud portion 28 which is engageable with a slotted opening 29 provided in the guide member 18. A spring 30 is disposed between the U-shaped body portion 24 and mounting block 23 on the side of the body portion 24 adjacent the stop-mounting block portion 25 and is operable to normally urge the body portion 24 and the split ring stop release blade 26 forwardly so that split" rings in the trough formed by the guide members l8 and I9 may not pass the blade 26. When the retainingrelease assembly 20 is caused to pivot on its axis in response to movement of an electric solenoid (not shown) the blade 26 is caused to be articulated out of the path of the split" rings in the trough and the retaining stud portion 28 is simultaneously caused to arcuately move through the slot 29 of the guide portion 13 and into engagement with the next succeeding split" ring in the trough. In this manner only one split" ring is released in response to each movement of the retainingrelease assembly 20. The split ring thus released may then travel by gravity down the trough formed by

guide members

13 and 19 to the split ring exitway 22 in the bed ll7 of the feed mechanism 115 and drop therethrough. It should be particularly pointed out that the retaining stud portion 23 may be adjusted for various sizes of split" rings by moving the block 27 forwardly or rearwardly on the block 24 and consequently moving the stud 24 in the slot 29.

Referring again to FIG. II, the feed mechanism 15 is mounted on the housing 112 so that the mechanism 15 is downwardly inclined from the hopper I1 and cantilevered over a split" ring placing arm assembly 31 and a spindle assembly 32 provided on the housing. A holding pin assembly 33 is provided in the housing adjacent the spindle assembly 32 and adjacent the pin arm and spindle assemblies, as well as a knife arm assembly 34 adjacent to the spindle assembly 32. Although, each of the above-identified assemblies are operated sequentially in cooperative engagement with each other, a clearer understanding may be had of the invention when a separate and independent understanding of the construction and operation of each of the assemblies is had before describing the combined integral relationship and construction of the assemblies.

Referring now more particularly to FIG. which shows to advantage the detailed construction and operation of the split" ring placing arm assembly 31, the placing arm assembly is pivotally carried by a shaft 35 journaled for rotation in the housing 12 and is disposed between the feed mechanism 115 and the spindle assembly 32 and is contiguous with one of the faces of the spindle. The placing arm assembly 3i comprises a flat, platelike arm portion 36 having an eyelet 37 in one of the terminal sides thereof being normally positioned and operable to receive a split" ring from the exitway 22 of the feed mechanism a guide bracket 33 suitably fastened to the shaft 33,'the bracket 37 including an upstanding rollerlike guide member 33'; and a placing arm cam 39 carried by a rotatable shaft 40. A spring 41 is provided in a recess portion in the housing 12 to constantly urge the bracket 37 and consequently the rollerlike guide member 33 against the cam 39. In response to the tracking movement of the guide member 33 as the cam 33 is rotated, the placing arm 36 is caused to move across the face of the spindle assembly 32. A "split" ring received from the exitway 22 of the arm 36 is carried across and over the face of the spindle assembly 32 onto the holding pin assembly 33 adjacent the spindle assembly 32 as hereinafter described. Movement of the placing arm assembly 31 is shown in dotted lines in the FIG. 5.

FIG. 6 shows to advantage the detailed construction and operation of the split-ring-holding pin assembly 33 of the present invention. The pin assembly 33 comprises a pin-spacing adjusting arm 42 having an upstanding split"-ring-holding pin portion .43 at one of its terminal ends and a pair of arcuately shaped slots 44 and 45 in the body portion of the arm 42 toward the terminal end opposite the portion 43; a guide arm assembly 46 pivotally carried by the arm 42 including a pair of downwardly projecting

studs

47 and 46 which are in engagement with the slots 44 and 45 respectively; and including an upstanding rollerlike guide member 40 below the placing arm cam 39. An adjusting screw 31 is laterally threaded into the body of the adjusting arrn portion 42 and into the slot 44, one of the terminal ends of the screw 51 being operable to urge against the stud 47. In response to tightening or loosening of the screw 51, the arm 42 and consequently the holding pin portion 43 carried thereby may be moved toward or away from the spindle assembly 32 to provide means of adjustment for various sizes of "split" rings. A spring 32 is provided in a recess portion of the housing 12 to constantly urge the

arms

42 and 46 including the rollerlike guide member 49 into engagement against' the cam 50. In response to the tracking movement of the guide member 49 as the cam is caused to rotate, the split"ring holding pin portion 43 is caused to be moved toward or away from the spindle assembly 32. When the pin portion is moved away from the spindle assembly 32, a split" ring may be received on the pin portion 43 from the eyelet 37 on the arm portion 36 of the split"ring placing arm assembly 31. When the holding pin portion 43 is on its normal position adjacent the spindle assembly 32, a split ring on the pin portion 43 is urged against a knurled peripheral sidewall portion of the spindle assembly 31 to be drivingly rotated by the spindle assembly 31 on the holding pin portion 43 as hereinafter later described. Movement of the holding pin assembly 33 away from the spindle assembly 32 is shown in dotted lines in the drawings.

FIG. 7 is a plan view of the knife arm assembly 34 of the present invention, while FIG. 11 shows to advantage the assembly 34 in a side elevational view as it may be observed from the right side of housing I2. The knife arm assembly 34 comprises a crank arm 53 pivotally mounted in the housing 112, a knife-holding chuck 54 carried at one of the terminal ends of the crank arm 53, a knife 55 carried by the chuck 54, a horizontally disposed rollcrlike guide member 56 carried by the arm 53 at the terminal end opposite the chuck 54, and a knife arm cam 57 carried on the rotatable shaft 40 below the pin arm cam 50. The crank arm 53 is provided with a downwardly projecting arm-retaining member 58. A spring 59 is provided in a recess portion of the housing 112 to constantly urge the retaining member 53 and consequently the crank arm 53 with the guide member 56 upwardly against the cam 57. In response to the tracking movement of the guide member 56, the crank arm 53 and consequently the chuck 54 and the knife 55 are caused to be moved upwardly and downwardly with respect to the spindle assembly 32 to permit the loading of a split ring onto the pin 43 as above described.

The assembly of the placing arm assembly 31, the holding pin assembly 33 and the knife arm assembly 34 upon the shaft 40 is shown to advantage in FIGS. 8 and 9. The shaft 40 is journaled for rotation as one of its terminals in the base portion of housing I2. A commonly known electric clutch 60 is provided on the shaft 40 and includes a gear-engaging portion 61. A driven gear 62 is journaled for rotation on the shaft 40, and is disposed above the electric clutch 60.

In operation, the electric clutch 60 is energized from a suitable power source to cause the gear-engaging portion 61 to engage the driven gear 62 during one complete revolution of the gear 62. In response to the rotation of the gear 62 the shaft 40 is caused to turn carrying with it the split ring placing cam 39, the "split"ring holding pin cam 50, and the knife arm cam 57. The solenoid in operative engagement with retainingrelease assembly 20 of the split" ring feed mechanism 15 is electrically interconnected with the power source and electric clutch 62 so that when the clutch 60 is energized the solenoid is simultaneously caused to operate the retaining-release assembly 20.

The operating cycle of the split" ring assembly machine commences with the split rings being placed into the vibratory hopper Ill and being caused to travel up the spiralled track I3 and through the hopper outlet opening 16 into the trough formed by the upstanding guide members 13 and I9 of the feed mechanism 15 to the retaining-release assembly 20 of the feed mechanism I5. When energy is supplied concurrently to the solenoid associated with retaining-release assembly 20 of the feed mechanism 15 and to the electric clutch 60 on shaft 40, the retaining-release assembly is caused to pivot on its axis in response to movement of the electric solenoid to cause the blade 26 to be articulated out of the path of split rings in the trough formed by the

guide members

18 and 19 of the feed mechanism I5 and to cause the retaining stud portion 23 to arcuately move through the slot 29 of the guide portion 113 into engagement with the next succeeding split ring in the trough of the feed mechanism 115 so that only one split" ring may travel down the feed mechanism 15 to and through the exitway 22 of the feed mechanism 15 and into the eyelet 37 of the split-ring placing arm assembly 31 on the face of the spindle assembly 32. Concurrently the gear-engaging portion 61 is caused to engage the driven gear 62 to cause the shaft 40 to rotate, carrying with it the ring-placing cam 39, the ringholding pin cam 50, and the knife arm cam 57. The respective rollerlike guide members 33, 49 and 56 are caused to trace the movement of the earns 39, 50 and 57 respectively to simultaneously cause the ring placing arm 36 with a split" ring in the eyelet 37 to move across and over the face of the spindle assembly 32 to eject the split ring; to cause the pin-holding portion 33 of the pin assembly 33 to move arcuately outward from the spindle assembly 32 to receive the "split ring; and to cause the knife 55 of the knife arm assembly 34 to move upwardly out of the path of the placing arm assembly 31 and the pin assembly 33 so that a split" ring may be received on the holding pin 43 as described above, Upon completion of one revolution of the shaft 30, the ring-placing arm 36 of the ringplacing arm assembly 31 is returned to its normal position under the exitway 22 of the feed mechanism and contiguous with the spindle assembly 32; the ring-hodling pin 43 of the pin assembly 33 is returned to its normal position adjacent the peripheral wall of spindle assembly 32 to urge the split ring on the pin 43 against spindle assembly 32; and the knife 55 of the knife arm assembly 34 is returned to its normal downward position on the split" ring held by the ring-holding pin 43. The spindle assembly 32 is caused to be rotated concurrently with the shaft 30 in the manner hereinafter set forth.

Referring now to FIG. 30 which shows to advantage the spindle assembly 32 of the present invention. The spindle assembly 32 comprises a flat, disclike wheel 63 carried by a shaft 64 which is journaled for rotation at the terminal end opposite the wheel 63 in the base of the housing l2, an electric clutch 65 including a gear-engaging portion 66 suitably fastened to the shaft 64; and a driven gear 67journaled for rotation on the shaft 64. The clutch 65 is electrically interconnected with the camshaft clutch 60 and the solenoid of the feed mechanism 15 so that energy may be simultaneously applied to each of these electrical components to cause the retaining-release assembly of the feed mechanism is, the split"ring placing arm assembly 31, the spindle assembly 32, the pin-holding arm assembly 33, and the knife arm assembly 34 to concurrently operate. The crank arm 53 of the knife blade assembly 34 is provided with an actuating block so that when the knife 55 reaches the split" portion 68 on top of a "split" ring on the pin 43, a microswitch 69 mounted to the housing l2 and electrically interconnected with the clutch 65 will be energized to cause the gear-engaging portion 66 to engage the driven gear 67 to cause the shaft 64 and the wheel 63 to be rotated. The peripheral sidewall of the wheel 63 is knurled to cause a split" ring held against the wheel 63 by the ring-holding pin 43 to be rotated and to be opened by the knife 55 as shown to advantage in FIGS. H and 12. A positive wheel stop pin 70 is provided on the shaft 64, and a microswitch 71 is mounted to the housing 12 in the path of pin '70. The pin 71 may be adjusted on the shaft to stop the wheel. The microswitch 71 is cooperatively associated with the clutch 72 on the motor drive shaft 73 shown to advantage in the driving train schematic of the FIG. 13. When the wheel stop pin 70 impinges on the microswitch 7i in the rotational travel of the spindle assembly shaft 64, electric current to the clutch 72 is shut off to clutch 72 causing the gear-engaging portion of the clutch 72 to disengage the driving gear 74.

Referring now to the PK]. 13, energy may be applied from a suitable source to a motor identified by the indicia M to drive the gear train identified by the

numerals

74, 75, 76, 7'7, 78, 67 and 62. A switch (not shown) is electrically interconnected to the respective electn'c clutches 72, s5, and 60 and the solenoid of the feed mechanism 15 through which energy may be selectively applied to simultaneously cause the operation of the several assemblies of the split ring assembly machine of the present invention as hereinbefore described and to permit spindle assembly 32 to continue its rotation to a predetermined point as above disclosed.

Having thus described a preferred embodiment of the invention which includes the teachings and principles therefor, it is to be appreciated and will be apparent to those skilled in the art that many physical changes could be made on the invention without altering the inventive concepts embodied therein. Hence, it is intended that the scope of the invention be limited only to the extent indicated by the appended claims.
