IMPROVD MACHINE FOR MAKING BALL-GRAIN..
T0 ALL WHOM ITMAY CONGERN: i
Bc it known that I, D. T. MUNGE, of Waterbury, in the county ofNew Haven, and State of Connecticut, have invented a new Machine for Making Ball-Chain; and I do hereby declarethe following, when taken in connecton with the accompanying drawings and the letters ofv reference mark-ed thereon, to be a full, clear, and' exact description of the same, and which said drawingsconstitute part of this specification, and represent, in-
Figurc 1, a front view.
Figure 2, a side view.
Figure 3, a top view.
Figure 4, a vertical central section.
Figure 5:), the rivet.
Figure 6, the blank from which the ball is formed.
Figure 7, the partial formation of the ball.
Figure 8,'the chain complete; and in Figure 9, a vertical section of the same.
This invention relatesto an improvement in the manufacture of what is termedball-chain, that is to say, a chain formed from hollow balls, the several balls being united so as to form a flexible chain.
Heretofore this kind of chain has been formed by passing a'link through each ball, and uniting the several links. This necessitates a suilicient distance between the balls to permit the union of the link, and is a comparatively expensive operation. By my invention the cost of thechain is very much reduced, and its appearance i. very much improved, inasmuch as the linkis dispensed with, and the balls lie in clo'se proximity to each other; and consists, rst, in ewa-ging the balls so as to lclosearound the neck of a double-headed rivet, then a second ball around the same rivet, and so on successive balls `arounda. separatefrivet lbetween each two balls; and second, a mechanism by which the chain is thus constructed.
To enable others to construct my improvement, I will proceed to describe the same as illustrated in the accompanying drawings. I I
A piece of metal of the proper size, as in iig.` 6, is bent in cylindrical form, a's in iig. 7, and the two: edges p l united. 'I I- prefer to use corrugated metal, but this is not essential. Fig. 5 is av double-headed rivet, formedin machines formed for the purpose. Then the cylinder in g. 7 is placed in proper dies,` or otherwise, and its two ends contracted so as to close around the neck of the rivet, as seen in iig. v9. Then a second ball is in like manner closed around the neck of one of 'the rivets, and another rivet placed'in the neck of the second ball to receive the third, and so on, leaving sufficient play around therivet to render the chain-flexible; and thus the4v balls are attached together in close proximity to each other, and without the employment ofthelinks heretofore uscd, and which detract verygreatly from the tasteful appearance of the chain.
I will now proceed to describe the machine by which I thus construct the chain.
A is the bed, B the frame which supports the mechanism, Cia. slide, arranged in guides, c, so as to be moved freely up and down by-a lever, .1), pivoted in the frame at CZ, and so as to move from the position in black to that in red, as denoted in fig.. 2, and m'ce versa. Upon the upper endof the slide lC is arranged a concave dic, E, the concavity corresponding to one-half of the ball of the chain to be produced; and centrally from the bottom of the said die ai hole is made, to receive a rivet, as denoted in g. 4, and so that' one head of the rivet will extend up into th`e die. Above the die E, in proper guides,f, are arranged slides, F, each carrying -in its inner-end a die, and the two dies combined correspond to the other half of the ball,` as denoted in lig. 4, and when. the'three dies, E and F F, are in the position as in g. 4, they together conform tothe shape ofthe ball to be produced. In the centre of the two dies F and F aperforation is made, so as to encircle the rivet, as. seen in iig. 4. The two dies F and F are moved by their respective-levers, G G, hung upon a common fulcru m, H-,l and above the two dies is arranged a plate,vI, through which a perforation is formed centrally with the dies, but smaller than the dies, vso as to support the last ball made while the next ball is being formed and attached, as seen Vin iig. 4. I v l,
The operation of the machine is as follows: When the die E stands in the position denoted in red, g. 2, insert the riv'et therein, as seen in iig. 4; lthen place the blank shown in iig. 7 into the die and close the Vtwo dies F, as denoted in red, g. 3, and in iig. 4; then raise the die E, and the form ofA the combined dies will contract the blank and close one end around the rivet setting in the bottom of the die, as seen in iig. 4; then open the dies, remove the ball and the rivet, which is' securely attached thereto; then place a second rivet and a second blank in the dies in like-manner, setting:r the first ball through theplate I, so that the rivet in the first ball will hang down through the upper dies, as seen in iig. 4; then close the dies as before, and the two ends of the blank are closed, the one upon the upper, and the other upon the lower rivet, and .so continuing, ladding ball after ball, until the chain is of the length desired. Thus the chain is produced in a very rapid manner, perfect inall its parts and connections, and neat and tasteful in its appearance. I have represented the several dies as moved by their respective levers, and this I nd to be the most convenient arrangement, but am not confined to this precise arrangement for operatinr the dies.
Having thus fully described my invention, what I claim as new and useful, anddesre to secure by Letters Patent, is-
1. The die E, combined with the dies F F, so as to operate to close the ball upon the rivets, substantially as herein set forth.
2. The arrangement of the plate I, in combination with the dies and F F, as and for the purpose specified,
