Two-piece cushion insert for U-bolt clamp assembly

A cushion strip having a substantially rectangular uniform cross-section and a pre-determined axial length adapted to be disposed about a cylindrical member secured to a support surface within a U-bolt clamp assembly, said cushion strip comprising:

• a planar inner surface for engaging said cylindrical member;
• and
• a substantially planar outer surface provided with a saddle portion for retainably engaging a U-shaped bolt member which attaches said cylindrical member to a support surface;
• whereby said cushion strip is positioned about the circumference of said cylindrical member within said U-bolt clamp assembly such that the free ends of said cushion strip are butted together at a point along the 180.degree. of said circumference of said cylindrical member that is furthest away from said support surface.

A U-bolt clamp assembly for securing a cylindrical member to a support surface, comprising:

• a U-shaped bolt member for attaching said clamp assembly to said support surface;
• fastening means for retaining said U-shaped bolt member to said support surface;
• and
• a two-piece cushion insert for absorbing vibration and shock adapted to be disposed about said cylindrical member, said two-piece cushion insert comprising a base member having a substantially planar lower surface in contact with said support surface, an upper surface provided with a concave portion for receiving said cylindrical member, and two flange portions each extending in a direction laterally outwardly from said concave portion, each said flange portion having a shoulder portion extending upwardly from said flange portion and inwardly toward said concave portion, and a cushion strip member of uniform cross-section having an outer surface provided with a saddle portion forming an arcuate recess for retainably engaging said U-shaped bolt member and a substantially planar inner surface for engaging said cylindrical member;
• whereby said base member and said cushion strip member operatively cooperate to provide a passageway for substantially circumferentially encompassing said cylindrical member, said cushion strip member being securely supported at the ends thereof between said U-shaped bolt member and said shoulder portion of each said flange portion of said base member.
