| 141 | Expandable load spacer | US735966 | 1991-07-25 | US5171114A | 1992-12-15 | George D. Dunn |
| An expandable load spacer having a suspension strip fixedly attached to a generally honeycomb, cellular void filler is disclosed for use between stacks of articles of freight in, for example, rail cars and other shipping vehicles or containers. The load spacer substantially eliminates the hour glass effect generally experienced in suspended dunnage devices, while at the same time significantly reducing the amount of sheet material required in the manufacture of those load spacers. | ||||||

| 143 | Method for cushioning a containerized shipment by railroad flatcar | US406866 | 1989-09-13 | US4957399A | 1990-09-18 | Anders Hove |
| A device for fastening containers and shifting platforms onto railroad cars using container pins fixed in a movable frame. The frame is fixed on the floor of a railroad car by a double-acting cushioning means. | ||||||
| 144 | Bracing and cushioning system and method for transporting massive loads | US941627 | 1986-12-15 | US4854792A | 1989-08-08 | Mark A. Cottone |
| A system and method for bracing and cushioning the impact of movable massive loads during sudden deceleration of a transport vehicle, such as created during humping of railway cars. Resilient elastomeric pads separate adjacent objects of the load with the thickness and density of the elastomeric material chosen to dampen typical impact forces without damage to the objects. The resilent pads are preferably formed with at least one face contoured to envelope the side of an object. Three types of resilient pads are disclosed for use in transporting massive sheet metal coils with one pad adapted for particular use at endwalls, another pad for use between coils, and yet another pad for use between mid-row coils and doorway dunnage. | ||||||
| 145 | Lading protection device | US609816 | 1984-05-14 | US4601461A | 1986-07-22 | Steve A. Brough; Mark P. Scott |
| A lading protection device in the form of a shock absorber for a railway car including a cylinder containing a piston and a body of hydraulic fluid normally captive between the front face of the piston and the closed end of the cylinder. A flow control valve assembly, centered in the piston, mounts an orifice bushing defining a constricted circular orifice. The assembly includes a valve stem slidable in the piston with a spring at its inner end for pressing the stem in a direction to seal the orifice. The piston has a fluid passage extending therethrough and an annular separator piston defines, with the main piston, a receiving space into which the fluid flows upon impact. The space in back of the separator piston is filled with a charge of gas under high pressure so that when the impact has been dissipated the gas pressure acting upon the separator piston restores the fluid to its normal position in readiness for a succeeding impact. The invention also resides in the structure of the orifice bushing and a system of seals and lubrication which minimizes leakage over a long period of time. | ||||||
| 146 | Void filler | US539621 | 1983-10-06 | US4585381A | 1986-04-29 | George C. Boyse |
| An expansible honeycomb-type void filler formed of stacked strips secured together at spaced and staggered positions to define cell walls which vary in length to provide vertically aligned shortened stretch-limiting walls which reduce hourglass-type distortion, has suspension means consisting of a supporting top strip of the stack and a suspension structural element, said suspension means also including parts movable in a direction lengthwise of the strips to provide openable cells between the suspension structural element and the supporting top strip of the stack. The void filler is also disclosed as having widened adhesive connections in an upper region, and as being formed of corrugated paperboard which is partially crushed. | ||||||
| 147 | Suspended type cellular void filler | US393662 | 1982-06-30 | US4516891A | 1985-05-14 | Paul A. Wnuk; Thomas J. Hamilton; Anthony Trassare, Jr.; Michael J. Oliver |
| An expansible cellular void filler for dunnage uses is formed of a stack of flat, bendable strips, each except the top and bottom of which is secured at alternating longitudinally spaced positions to an overlying strip and to a subjacent strip, the secured positions being aligned in rows in a direction perpendicular to the planes of the flat strips, the spacing between at least two such rows being less than the spacing between other rows, so that when the strips are moved apart and bend to form cells, the cell sidewalls formed by the portions of the strips which extend between said two rows move toward a straight planar relationship prior to the sidewalls of other cells, and limit the expansion of the filler. | ||||||
| 148 | Air suspension system for piggyback transportation of goods | US118642 | 1980-02-04 | US4344656A | 1982-08-17 | Robert C. Masterson, Jr.; R. Gordon Thomas; John G. Johnson |
| A system for preventing damage to cargo shipped in air-ride suspension semi-trailers loaded on railroad flat cars which comprise at least part of a freight train is provided. The system comprises a coupling element connected to the air brake line of the freight train. The coupling element is connected to an air reservoir mounted on the flat car or on the semi-trailer and supplies compressed air to the reservoir from the brake line of the train. The coupling element includes a valve to prevent air from flowing from the train brake line to the air reservoir when the air pressure in the brake line drops below a predetermined safety level to prevent unwanted activation of the train's brakes. The air reservoir is connected to the air line of the semi-trailer and provides compressed air to the air bags which comprise the air suspension system of the semi-trailer. When the bags are inflated with compressed air from the brake line of the train, they suspend the semi-trailer above its rear axles and cushion the semi-trailer from the lateral sway and rough ride of the flat car. | ||||||
| 149 | Means for preventing dry burn in a paper plastic dunnage bag | US520014 | 1974-11-01 | US3960281A | 1976-06-01 | Robert L. Reeves |
| A dunnage bag having multiple outer plies of paper and an inner ply of plastic has a baffle means opposite the inflation valve to prevent dry burn constituting either a piece of corrugated paper or a similarly flat member of sufficient included area to baffle substantially all of the air projected through the valve and having an expanded thickness sufficient to separate the confronting surfaces of the plastic ply a discrete distance so that the air stream directed through the valve will be diffused transversely and thereby dissipate any vibratory forces tending to produce a dry burn on the plastic ply. | ||||||

| 152 | Method and apparatus for absorbing impact forces | US3653334D | 1970-03-27 | US3653334A | 1972-04-04 | MEIER WILLIAM A |
| 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.

| 153 | Shoring device | US3554135D | 1968-10-01 | US3554135A | 1971-01-12 | DUVALL WILLIAM C; TOMCSAK STEPHEN L |
| An inflatable member having a body composed of opposed plies of air impervious, pressure retaining flexible material which are joined together along their peripheral edges to form a seam around the entire body of the member. The member has at least two pneumatic chambers with at least one crossover connecting any two such chambers and a single valve means connected with the body through the seam. The principal application for the inflatable members of this invention is as a dunnage device for shoring merchandise, for instance, in the storage compartment of a transport vehicle or in a warehouse. Each chamber of the pluralchambered device is the size and capacity of the ordinary single inflatable dunnage bag but inflation and deflation of the device is accomplished through a single valve assembly. Since the valve extends through the seam of the dunnage device it is readily accessible to the source of the inflating medium for inflating the bag. These devices are also designed with an open area between each pair of chambers so that the device may be positioned to avoid obstructing or interfering structures in the storage area.
