IMPROVED APPARATUS FCR WELDING CHAIN-LINKS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, HENRYREYNOLDS, of Aurora, in the county of Cayuga, and State of New York, have invented certain new and useful Improvements in Machines for XVelding GhninvLinks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to thel accompanying drawings, making e part of this specif fr ,g Figure l represents a-front elevation of the machine.

Figure 2 represents n vertical section through the seme, teken at 'the line C D of tig. 1.

Figure -3 representsa. horizontal section through the machine, taken et the line A-B of fig. i'.

Figures 4 and 5 represent the anvil and hammerdies, for welding and iinishing the links, on an enlarged scale.

ASimilar letters of reference, where they occurin the separate figures, denntelihe parts ofthe machine in all of the drawings.

. The object and purpose of myinvention are to weld nplinks in forming chains, by a series of graduated blows between dies of peculiar form, and so that no fin shallbe formed at the line of meeting of the dies, and thus weld and iinish the links at the Sametime.

, To enable others skilled in the art to make and use my invention, I will proceed to describe the saine with reference to the drawings.

In a suitable housing or trame, E, is arranged n crank or eccentrie-shnft,l which may be turned or stopped by an endless belt running upon the first pulley G, or shipping it upon the loose one H, as the ense may be.

On the end of said cinnlshaft, opposite to the fastand Iloose pulleys, is a balance ily-wheel, l', for giving Stea'diness ot' motion to the shaft, and to the hammer J, connected to it by the pitman or crank-rod K, said ,hammer moving upon guides or ways, L, in the hous- 1 the under part oi' the hammer J, e port-ion of the shaping-die is formed, better seen nt` a a, iigxfi, this die working, not against, but into the under or Mvll-dle o c, will he explained. l Upon n shaft, M, supported in the housingor frame E and at or nea-r the lower end thereof, there is en. gtlju'table cam, N, which can he set, and then fastened to said shaft. g n l.

And upon one of the ends of this shaft M, th'ere is arranged n hand-lever, O, which can, if found desirable, he made adjustable by its set-screw e taking into one of a series of holes in en are, i', 'scented to the Shsfb M.. ,j

Upon the cam N, rests the anvil P, which l cnn he raised up or let down by said cam,tbrou h' the lever O.

Theicnnubkis slipped upon the shaft M; and when wdjusted, is fastened b y :i set-screw or other device,f, and by shift-ing the cam or-the lever upon the shaft,

v and then fastening them, the anvil can-gzberaised ce kept at its wnrkingfposition with less oni-more motion, as the character ot' the work muy require.

The anvil movesand is guided initsmovementsby v the die c, and their line of contet is within the under die, leaving myspace or `joint-'in w iich nu objectionable fin or die-mark cnn he made.y Thehammer does not touch the anvil, but the hammerdieeriters .into the anvildie, and .when the twodies pproach each other as near as they can, the spac'- ruled-:hy the two unequal cavities in the dies' makes complete circular cavity,in'cross-section, for giving that'nferm to the welded link, as seen in ig. 4.

The hammer and' sdie move v space, which is defined by thee-mnh on the shaft F.

The anvildie` is moved up gradually, so that the first blows of the hammer-die maybe light, just reaching the metal to ne welded, out by bringing down the lever or raising the cam N, the miv-il and its die are brought nearer and negre to the hammer-die, and thus receiving increased o V "adu'eted blows, until the hammer-die entersijhe anvil-die, and not only com.- pletcs the weld, lbut shapes and neatly finishes the throughs uniform 'v link, so that there is scarcely :t iinor "a, die-morirl perceptible.J

Dierent dies may bensed in the machine' for difv'ferent-sized links, and Vthe 'adjust-ment of the cam is suoli that vthe anvil'eflie vcan he so accuratelyraised that the upper die will work into itwithout jamming or sticking. From the pofntsn, of the anvil -die c, it flares outward,1sothat the upper die is readily worked into it, withbut-nny danger of marring it.

I amnware that hammers or drop-dies have been used,'fa.iid thntmvilswth dies` in them havealso been used. 'These Ido not e-lim; hut hnvingthus fully described my invention,
