Abstract
The invention contemplates a chain-making machine having the capability of making continuous chain wherein successive links follow a predetermined relative size and shape, with selective applicability to different input materials, including wire and/or flat ribbon, for the respective successive links. For each link-forming cycle, the production of one kind of link may call for one kind of motion in a manufactured-chain accumulating device, while production of another kind of link may call for a different kind of motion in the accumulating device, yet the machine includes provision for proper accommodation of these different motions, as each different link is formed, to the end that the resulting product will be free of entanglement.
Claims8
A machine for the manufacture of chains comprising:
- first and second substantially symmetrical machine sections, each of said first and second machine sections including means for operating upon the chain to be formed;
- a slide bearing a rotating unit having pincer tools for engaging the links of the chain to be formed, said slide being constructed and arranged to be displaceable between first and second working positions corresponding to said first and second machine sections;
- means for displacing said slide;
- first and second continuously rotating camshafts corresponding to said first and second machine sections;
- tappet means selectively engageable between said means for displacing said slide and said continuously rotating camshafts for transmitting the motion of said camshafts to said displacing means to thereby displace said slide;
- locking means to lock said slide at said first and said second positions;
- and
- at least third and fourth camshafts correponding to said first and second machine sections, engagement means engaging between said first and second continuously rotating camshafts and said third and fourth camshafts, respectively, to alternately operate said third and fourth camshafts to thereby alternately actuate said chain operating means in said first and second machine sections.
