Application April 15, 1553, Serial No. 349,052

11 Claims. (Cl. 59-27) This invention relates to a machine for linking together costume jewelry pieces and, more particularly, to certain improvements in the machine for handling and closing costume jewelry links disclosed in our co-pending application Serial No. 215,542, filed March 14, 1951, now Patent Number 2,680,344, patented June 8, 1954.

The links disclosed in our said co-pending application consist of breached wire circles which are held together in bar form by a suitable cement and which are readily removable from the bar ser'iatim to be closed to join together a pair of costume jewelry pieces.

Cate object the invention is the provision of a machine for removing the links from a said bar seriatirn for feeding the links to a gripping means and for closing the links as they are held in said gripping means.

Another object of the invention is the provision of novel means for shifting the links angularly accurately to position the links in said gripping means.

Still another object of the invention is to construct the means for feeding the links to the gripping means in such manner that the accurate angular positioning thereof is maintained.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The machine for closing costume jewelry links, according to the present invention, includes a base from one end of which a post 26 projects vertically. Fixed on the post 26 near its upper single acting spring is a return compressed air press 27 having an intake line or hose 28 and a piston rod 30 which is forced downward by compressed air and restored upward by a spring in known manner.

Mounted on base 25 is a frame plate 31 above which a second plate 32 is spaced by corner posts 33, said

plates

31 and 32 having mounted between them a double-acting compressed air press 34. The press 34 is provided with upper and lower

air intake tubes

35 and 36, respectively, which provide for positive movement of the cylinders piston rod 37 in either vertical directions, see Figs. 5 and 9.

Compressed air presses such as those indicated at 27 and 34 are extremely well known and available in many diiferent sizes from Air-Mite of Chicago, Illinois, and, therefore, it is not deemed necessary to illustrate or describe their internal construction.

The piston rod 37 of the press 34 extends upward through aligned openings in the plate 32 and in a plate 38 secured atop the latter and has an upwardly extending feeder bar 40 secured to the upper end thereof in any suitable manner, said feeder bar extending upward within a housing block 41 fixed in the opening of plate 38. Housing block 41 is suitably hollowed out and cut away as shown to receive a facing block 42 which is secured thereto by screws 43 and which has in its inner face an accurately cut vertical groove 44 in which feeder bar 40 slides. Pike erabty a plate 45 is extended across groove a above its center to pre out iateral movements of feeder bar 46, see also Fig. 2. Below plate 45 the longitudinal center groove 44 is deepened to form a lubrication well 46. At its upper end block 42 tapers somewhat and has its upper edge formed into a concave arc as at 47. Also the stock at either side of the upper end of groove 44 is cut away so that the nose 47 forms one jaw of a gripping device whose other jaw is the concavely arcuate upper edged nose 48 of a lateral and upward extension 50 of a block 51 pivoted to housing 41 at its lower end, as will 1'; be described presently.

As best shown in Fig. 9, the face of extension 50 abuts the groove 44 and the nose 48 thereof is positioned to cooperate with nose 47 to grip an article fed up through said groove by feeder bar 40, see also Fig. 3.

Near its lower end, block 51 is provided with a bore 52 in which is journalably mounted a sleeve 53 through which a bolt 54 extends into the housing. Block 51 and its extension 50 are thus pivoted to said housing and nose 48 is capable of being swung away from nose 47 to in order to maintain nose 47 in gripping position a rod 55 extends rearward from the block 51 and near its free end has a depending rod 56 secured thereto. Coiled about depending rod 56 is a coiled spring 57 which acts against plate 38 and against the rod 55 to rock block 51 to normal position, that is, the position in which gripping nose 48 is adapted to cooperate with nose 47 Extending rearwardly from housing 41 at a slight angle is a bar 58 which is supported by an L-bracket 60 and has a generally circular cross-section with the upper porseries of wire links 62 having the same configuration as the groove and arranged in cemented-together relation- 3 ship, see also Fig. 6. The bars of links 62 preferably are carried on a rod 63 with which they are inserted into the open end of groove 61, after which the rod 63 is removed.

After removal of the rod 63, a follower 64 is inserted into the groove 61 beind said links and acts to move the latter toward the housing 41. Follower 64 is pulled along by a string or cord 65 which is threaded over suitably mounted

pulleys

66 and 67 and is secured to a counterweight 68 which provides the motive power for the follower. The groove 61 extends clear to the groove 44 in facing block 42 described above so that as follower 64 pushes them forward, the links 62 are detached one by one and raised to the gripping

noses

47 and 48 by the feeder bar 40.

In order to assure that the breach of each link 62 is positioned Vertically for feeding by bar 40 the following means are provided, see Figs. 4, 9 and 11. A plate 70 is secured atop bar 58 at the forward end thereof by screws 71 and has the rear edge 72 thereof undercut on an incline.

Thus, as the links 62 are fed along in groove 61 they pass beneath said incline and if the breach therein is not centered vertically, the links are cammed to the proper angular position. The plate 70 extends beneath the extension 50 of block 51 and has its forward edge out at an angle to parallel the same with the grooved face of facing block 42. Said angled edge is provided with a longitudinal groove 73 in which a thin rod or pin 74 is located. A spring 75 located in a well at the base of groove 73 tends to project the rod out of the groove. As best shown in Fig. 9, the action of spring 75 forces rod 74 partly out of the groove and against facing block 42, said rod spanning feed groove 44. As the links 62 are fed upward by feeder bar 40 they must of necessity contact the rod 74.

The construction is such that a link 62 fed into groove 44 by follower 64 is moved upward by feeder bar 40, during which movement it engages rod 74 and forces the same back into groove 73 against the tension of spring 75; and if the link is not positioned with its breach centered vertically, the engagement thereof with said rod rotates the link to the proper position.

To further insure that the links 62 move upward with their breach centered vertically, the side of the extension 50 facing the block 42 is formed midway of its height with a transverse groove in which a short rod is positioned, see Figs. 3 and 9, and which is resiliently urged into an extended position by a spring 91 housed in a well formed in the extension 50. Thus, the rod 90 functions exactly as the rod 74 does to turn the links 62 to center their breach vertically in the event any rotation of the links should take place between the time that they leave the rod 74 and reach the rod 90. v

To further insure that the links 62 move upward with their breach centered vertically after they pass

rods

74 and 90, facing block 42 at the back of groove 44 is provided with an elongated groove 98 communicating with the rear face of the block by means of opening 99. A rod fits Within groove 98, as shown in Fig. 9, and is beveled at its lower end, as at 101. The rod 100 is normally urged into 'groove 44, as shown in Fig. 14, by means of tongue 102 integrally formed and bent at right angles to a leaf spring 103 secured to the back of block 42 by means of a screw 104 and a spacer washer 105.

Thus, as shown in Fig. 15, as the link 62 moves upwardly past the

rods

74 and 90 with its breach centered vertically by the latter, the ends of the link engage both longitudinal sides of rod 100. As the ends move upwardly along the rod 100, the beveled portion 101 of the latter is engaged by first the link 62 and then feeder bar 40, rocking the rod into groove 98 about the end of tongue 102 as a fulcrum, as the link moves upward. Since the ends of the link 62 are always in engagement with the longitudinal sides of rod 100 just before they are rocked into groove 98, the vertical centering of the breach is assured. After the link 62 and feeder bar 40 pass the end of tongue 102, the upper portion of rod 100 will likewise be rocked into the groove, as shown in Fig. 12, delivering the link to the

noses

47 and 48 with the breach thereof vertically centered.

Referring again to Fig. 5, the upper edge of feeder bar 40 is cut away to form a concave seat 76 for engaging the links 62. Also to prevent inadvertent rotative movements of the links after they pass the

rod

74 and 90, seat 76 is provided with serrations or teeth 77.

The construction is such that feeder bar 49 moves the links upward one by one to the gripping

noses

47 and 48 which holds the same under tension of spring 57. The face of extension 50 is, of course, suitably formed to allow a link 62 moving upward in groove 44 to cam the same outwardly a short distance. While a link is held between

gripping noses

47 and 48 with the feeder bar 40 still engaging the same, the pair of jewelry pieces that are to be connected by the link are engaged over opposite sides of the latter and the press 27 is actuated to close the same. The means operated by the press 27 to close the links consists of a chuck 78 which is mounted on the piston rod 30 of the press, as shown in Fig. 1. In obvious manner depression of chuck 78 onto a link 62 held by

noses

47 and 48 closes the same.

A closed link is removed from gripping

noses

47 and 48 by the next link fed upward by the feeder bar 40.

it will readily be seen, therefore, that means is required to operate the lower press 34 to raise feeder bar 40 and maintain the same in raised position, to operate cylinder 27 to depress chuck 78, and to operate the press 34 in reverse to lower feed bar 40 to pick up another link 62.

Means to these ends are extremely well known and the diagrammatic showing thereof in Fig. 7 is deemed sufficient for a full knowledge of the invention. The

air tubes

35 and 36 for operating the press 34 in opposite directions, are connected to a foot switch or valve 30 which is operable in either of two directions to connect one or the other of said tubes to a main tube 81 leading to a source of compressed air such as a tank 82. Tube 28 for upper press 27 is connected to a foot switch or valve 83 which in turn is connected to tank 82 by a tube 84.

It will readily be seen that to obtain the required sequence of operations described above, all that is required is to operate valve 80 in one direction, operate the valve 83 and then operate valve 30 in the opposite direction.

In Fig. 12, there is illustrated an earring 85 which has its upper ear engaging portion 96 connected to a lower pendant portion 97 by means of a link 62 pressed to a closed position by a machine constructed in accordance with the present invention.
