Boiler tube clamp assembly

A clamp assembly adapted to embrace a series of tubes and maintain the tubes in parallel spaced relation, said assembly comprising:

• first and second elongated clamp halves each having an axially spaced series of first slots opening in a first side edge of the clamp half with a series of first land portions positioned respectively therebetween and each having a series of second axially spaced slots opening in a second side edge of the clamp half with a series of second land portions positioned respectively therebetween;
• the clamp halves being positioned in superimposed relation with the first land portions of said first clamp half received in the second slots in said second clamp half and the first land portions of said second clamp half received in the second slots of said first clamp half;
• the first slots being dimensioned such that each first slot of said first clamp half coacts with a respective first slot of said second clamp half to define a series of axially spaced openings sized to pass the tubes;
• the first land portions of said first clamp half coacting with the second land portions of said second clamp half to define a first axially extending passage along a first longitudinal side edge of the clamp assembly and the second land portions of said first clamp half coacting with the first land portions of said second clamp half to define a second axially extending passage along a second longitudinal side edge of the clamp assembly;
• and
• the clamp assembly further including first and second rods respectively slidably received in said first and second passages.

A clamp assembly adapted to maintain a plurality of tubes in parallel spaced relation, said clamp assembly comprising:

• first and second elongated clamp halves;
• each clamp half having a series of axially spaced first slots opening in a first longitudinal side edge thereof separated by a corresponding series of axially spaced first land portions;
• each clamp half having a series of axially spaced second slots opening in a second longitudinal side edge thereof separated by a corresponding series of axially spaced second land portions;
• said first slots being axially staggered with respect to said second slots so that said first slots are laterally aligned with said second land portions and said second slots are laterally aligned with said first land portions;
• said clamp halves being positioned in superimposed relation with outboard portions of said first land portions of said first clamp half positioned in said second slots of said second clamp half, said second land portions of said first clamp half positioned in said first slots of said second clamp half, inboard portions of said first slots of said first and second clamp halves coacting to define an axially spaced series of openings to respectively pass the tubes, outboard portions of the first land portions of said first clamp half coacting with the second land portions of said second clamp half to define a first passage extending along a first longitudinal side edge of the assembled clamp halves, and outboard portions of the first land portions of said second clamp half coacting with the second land portions of said second clamp half to define a second passage extending along a second longitudinal side edge of the assembled clamp halves;
• the clamp assembly further including first and second rods respectively slidably received in the first and second passages.

A clamp assembly including a pair of elongated clamp halves adapted to coact to maintain a series of tubes in parallel spaced relation, characterized in that:

• the clamp halves coact in their assembled relation to define a series of axially spaced openings to pass respective tubes and first and second passages extending axially along the respective sides of the assembled clamp halves;
• the clamp assembly further includes first and second rods respectively received in said first and second passages;
• the clamp halves are identical and are assembled with one clamp half inverted with respect to the other clamp half;
• each clamp half includes a series of axially spaced planar main body portions separated by a series of first axially spaced slots opening in a first side edge of the clamp half;
• in the assembled relation of the clamp halves, the planar main body portions of one clamp half are superimposed on the planar main body portions of the other clamp half and the first slots in one clamp half coact with the first slots in the other clamp half to define the openings for passage of the tubes;
• and
• each clamp half further includes a series of axially spaced first passage defining portions proximate said first side edge, raised above the plane of the planar main body portions, and formed as lateral extensions of the respective planar main body portions;
• a series of second axially spaced slots opening in a second side edge of the clamp half in respective lateral alignment with the planar main body portions;
• and a series of axially spaced second passage defining portions proximate said second side edge, raised above the plane of the planar main body portions, and disposed in respective lateral alignment with the first slots.
