Abstract
An assembly ties together a plurality of boiler tubes to increase their mechanical stability and maintain a uniform spacing between adjacent tubes. A tie bar has a plurality of periodically spaced fingers extending from a cross member to form openings between adjacent fingers with in which the boiler tubes tightly fit. A retainer projects orthogonally from ends of some of the fingers. A locking bar has wedges spaced along one edge which engage the retainers clamping the boiler tubes between the fingers of said locking bar. Stops and brackets attach to the boiler tubes to support the fingers and cross member, thereby holding the tie bar in place during assembly.
Claims13
A boiler comprising:
- a housing which forms a chamber;
- a plurality of boiler tubes within the chamber;
- a tie bar mounted on the tubes and having a plurality of fingers extending from and spaced periodically along a cross member to form an opening between adjacent fingers within which a boiler tube is located, and having a retainer projecting from at least some of the fingers;
- a locking bar having wedge elements spaced along one edge for removably engaging the retainers and an opposite edge abutting said boiler tubes;
- and
- a support means attached to at least some of said boiler tubes and engaging said tie bar.
An device for connecting a plurality of tubes comprising:
- a tie bar having a plurality of fingers extending in a first direction from and spaced periodically along a cross member to receive a tube between adjacent fingers, and having a separate retainer projecting from at least some of the fingers in a second direction transverse to the first direction;
- and
- a locking bar having wedge elements spaced along one edge for engaging the retainers and clamping the tubes between said locking bar and the cross member of said tie bar.
An device for connecting a plurality of tubes comprising:
- a tie bar having a plurality of fingers from and spaced periodically along a cross member to receive a tube between adjacent fingers, and having a separate retainer projecting from at least some of the fingers;
- and
- a locking bar having wedge elements spaced along one edge which removably engage the retainers and clamp the tubes between said locking bar and the cross member of said tie bar.
