Abstract
The forged chain link and flight assembly and method of making same provide for use of a hollow sleeve for engaging link ends together and engaging flights to the link through engagement of a suitable connector through the flights and the sleeve to make the flights easily replaceable. As an alternative embodiment a solid sleeve incorporating threaded ends is also proposed for use in engaging flights to a forged chain link.
Claims13
A forged chain link and flight assembly comprising a forged chain link having a male end and a female end which cooperates with an opposite end of an adjacent link to form a chain, each end having a throughbore therein which cooperates with a throughbore in the opposite end of an adjacent link to form a bore for receiving a connector therein for creating a forged link chain wherein the links pivot relative to each other, the improvement comprising;
- the connector being configured in the form of a hollow sleeve extending through substantially an entire length of the bore, a separate flight which is tightenable against each lateral side of the female end of a chain link with a nut and elongate bolt, the elongate bolt extending through a bore in each flight and the hollow sleeve which joins the links together.
A method for producing a forged chain link and flight assembly comprising a forged chain link having a male end and a female end which cooperates with an opposite end of an adjacent link to form a chain, each end having a throughbore therein which cooperates with a throughbore in the opposite end of an adjacent link to form a bore for receiving a connector therein for creating a forged link chain wherein the links pivot relative to each other, the improvement comprising engaging a flight to each lateral side of the female end of a chain link using a nut and elongate bolt which extend through the connector which joins the links together, the method including the steps of:
- engaging a male end of a link with a female end of an adjacent link;
- placing a connector into aligned bores of the engaged link ends;
- positioning a flight over each lateral side of the female end of the link;
- and tightening down the flights against the engaged links using a nut and elongate bolt, the elongate bolt extending through a bore in each flight and the connector.
A forged chain link and flight assembly comprising a forged chain link having a male end and a female end which cooperates with an opposite end of an adjacent link to form a chain, each end having a throughbore therein which cooperates with a throughbore in the opposite end of an adjacent link to form a bore for receiving a connector therein for creating a forged link chain wherein the links pivot relative to each other, the improvement comprising engaging a separate flight to each lateral side of the female end of a chain link using the connector which joins the links together, the connector comprising a hollow sleeve which seats within the bore and has a threaded interior and receives a bolt into each end thereof, the bolt passing through a respective flight to one side of the female end and extending into the sleeve.
