Abstract The practice of the method disclosed herein acts to absorb the effect of impact forces placed on articles shipped in a railroad car, or other moving vehicle, to prevent or minimize movement of the articles relative thereto. A strap adapted to be disposed about a package being transported is located within a cushion seal, which is subsequently crimped to interlock the strap and seal. The seal is then secured to the base of the transporting member, which will act to absorb the imposed shock loads. The impact energy on the strapped article is converted into heat due to the high friction developed tending to move the strap through the cushion seal. With the cushion seal disclosed herein, a controlled slippage of the strap and thus controlled movement of the article is obtained, which prevents the article from becoming damaged due to hitting the end of the car, or another article in the car, or from sliding into a position where it would block an unloading doorway. The holding power of the cushion seal is of lesser magnitude than the strap tensile force, so that the article will move before the strap is broken.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
Load retaining means comprising: means defining an attachment surface; a load positioned adjacent said attachment surface; a strap positioned against said load; and a seal having a flat main body portion fixedly mounted on said attachment surface, said seal having legs extending from said main body portion toward said attachment surface and embracing said strap between said main body portion and said legs, said legs being crimped into engagement with said strap to provide mating convolutions in the strap and the seal whereby the seal frictionally engages the strap to absorb impact forces imposed on the load during sudden changes in movement of the attachment surface.
Claim 2
Dependent Claim
106 words

Claim 3
Dependent Claim
24 words
Load retaining means as set forth in claim 1 wherein said seal includes a single leg at each side of said main body portion.
Claim 4
Dependent Claim
25 words
LoAd retaining means as set forth in claim 2 wherein a recess is provided in said main body portion adjacent each end of each leg.
Claim 5
Dependent Claim
40 words
Load retaining means as set forth in claim 1 wherein a plurality of openings are provided in the main body portion of said seal, and wherein fasteners extend through said openings to fixedly secure the seal to said attachment surface.
Claim 6
Dependent Claim
24 words
Load retaining means as set forth in claim 1 wherein at least two legs are provided on each side of said main body portion.
Claim 7
Dependent Claim
30 words
Load retaining means as set forth in claim 1 in which a single leg is provided at each side of said main body portion, each leg having tapered end portions.
Claim 8
Dependent Claim
34 words
Load retaining means as set forth in claim 1 wherein tabs extend outwardly from said main body portion adjacent the ends of said legs to assist in maintaining said seal on said attachment surface.
Claim 9
Dependent Claim
22 words
Load retaining means as set forth in claim 1 wherein said strap is a thin, flat metal member that encircles said load.
