| 61 | Hitch retarder | US409315 | 1989-09-19 | US5015131A | 1991-05-14 | Kenneth D. Schmidt; Jan D. Holt |
| A retarder (97) for a railcar hitch (1) is disclosed. The hitch has an erected and a retracted position and the retarder slows movement of the hitch towards its retracted position. The retarder comprises a cylinder (99) fixedly mounted on a railcar. A piston (101) is movable in the cylinder. A rod (115) attaches the piston to the movable hitch element so that preferably only axial loads act on the piston during operation of the hitch. The fluid compressed in one end of the cylinder by the piston is bled (metered) from the one end of the cylinder so as to control the rate of movement of the movable element during hitch retraction. | ||||||
| 62 | Captive dunnage fitting | US507037 | 1983-06-23 | US4553888A | 1985-11-19 | Charles F. Crissy; Paul M. Holmes |
| A dunnage bar system for freight containers utilizing a fixed elongated track cooperable with fittings mounted upon the opposite ends of an elongated bar. The bar fittings including a head captive within the associated track affixed to a neck extending through an elongated slot wherein the fitting may be adjusted along the track length and openings formed in the track selectively cooperate with head projections to lock the fitting against longitudinal track displacement. The dunnage bar fittings are releasable from the track openings by a rotative movement of the head either with, or relative to the bar, and with a relatively movable head a latch is associated therewith locking the fitting head relative to its bar. | ||||||
| 63 | Damage prevention void filler for separating loads during transit | US465522 | 1983-02-10 | US4494897A | 1985-01-22 | Eugene A. Rogers |
| A collapsible, corrugated damage prevention device for separating freight in transit in railroad cars, trucks, and the like is provided and includes an outer tube like member and a collapsible spreader core inside the outer tube and at right angles to the sides of the outer tube. One version provides an outer tube like member and a second tube like member inside and at right angles to the outer tube. Another version provides a U-shaped outer section with outwardly extending flanges covered with a cap sheet to provide a hollow interior. The sides of the void filler are scored to allow each side to be easily folded outwardly from the core member thus disposing the entire device in a flat configuration which can be easily stored when not in use. | ||||||
| 64 | Side load spacer | US253771 | 1981-04-13 | US4386881A | 1983-06-07 | Henry L. Liebel |
| A load spacer is disclosed for filling the void between containers or articles in a railway boxcar or other freight shipping vehicle or container and the sides thereof to prevent shifting of the load. The load spacer is an expandable, collapsible honeycomb structure which includes a generally planar suspension member laminated to the top of the honeycomb structure. The suspension member includes side portions extending laterally beyond either side of the honeycomb structure and is provided with a score line permitting one side portion to be bent to a position generally perpendicular to the top surface of the suspension member. This side portion includes a pair of flaps which are bendable inwardly over the top surface of the suspension member to prevent the one side portion from being bent beyond the perpendicular. In use, the other side portion rests on the top of the article of freight while the side portion bent into the perpendicular relationship lies against the vertical side wall of the container. This relationship prevents the load spacer from falling down between the load and the side wall of the vehicle during use. A bendable wire runs along the length of the one side portion of the suspension members having the flaps to hold the flaps in their inwardly bent position during use. | ||||||
| 65 | Cellular void filler | US341093 | 1982-01-20 | US4372717A | 1983-02-08 | James D. Sewell; Norman E. Gordon |
| An expandable honeycomb slab constructed from sheet material of corrugated paperboard, for filling load voids within a container carrying articles of freight. A plurality of horizontal cell rows, each containing a central diamond-shaped cell straddled by a pair of square-shaped cells, is stacked in vertical relation. Vertically adjacent corners and apexes of the cells are interconnected so as to allow vertical expansion of the suspended cellular array under its own weight. The vertically aligned, centrally positioned diamond-shaped cells provide vertical support and horizontal rigidity for the array, effectively preventing the honeycomb slab from assuming an hourglass configuration. | ||||||
| 66 | Dunnage bag fill valve device with integral combination baffle, plug retainer, and bladder separator | US740951 | 1976-11-11 | US4073389A | 1978-02-14 | Barry R. Angarola; James A. Robbins |
| An inflatable dunnage bag having a relatively thin-film, flexible, gastight bladder is provided with a fill valve device extending from the exterior of the bag to the interior of the bladder. The fill valve device includes a hollow housing which is mounted on one end by means of a flange to the outer surface of one wall of the bladder. Within the housing there is an orifice and a plug member which is spring-biased in sealing engagement against the orifice. The plug member extends beyond the end of the housing and into the bladder. A flange on the end of the plug member in the bladder is substantially parallel to, and spaced away from, the mounting flange/bladder wall interface to provide a separation of the bladder walls, to deflect the filling gas to prevent impingement upon the bladder wall opposite the housing, and to provide an anti-blowout stop thereby preventing the plug member from being blown out of engagement with the valve housing when the bag is subjected to high compressive loads. | ||||||
| 67 | Inflatable dunnage | US30585372 | 1972-11-13 | US3847091A | 1974-11-12 | HOLT J |
| Air bags are provided along the length of the car and are inflated to apply pressure against the lading in a generally transverse direction. The air bags may act upon panels or upon a flexible covering. Various lading loading schemes are accommodated by applying different amounts of pressure to individual bags. Thus the problem of lateral shift of the lading is avoided or reduced.

| 68 | Inhibition of end-to-end sloshing, longitudinal of the direction of movement, within confined bodies of liquid in transit | US3795204D | 1972-06-12 | US3795204A | 1974-03-05 | WAGUESPACK W |
| The invention is a method, and apparatus specifically designed to carry out the method, of lessening and substantially eliminating the sloshing and surging within bodies of confined liquid in transit as in a railway tank car.

| 69 | Interlocking device for inflatable bulkheads | US3724395D | 1971-10-26 | US3724395A | 1973-04-03 | ENOCHIAN S |
| A safety latching mechanism for use with bulkhead cushioning systems that employ a wall-type member, a lading-engaging panel attached to the wall-type member and an inflatable envelope disposed therebetween. When the bulkhead is not in use the envelope is deflated and the lading-engagement panel is automatically and releasably maintained in close relation to the wall-type member by the latching system provided herein. Before the bulkhead can be used the latching system must first be disengaged so as to prevent damage to the bulkhead which might result from inflation of the envelope when the panel and walltype member are latchably secured in close relation.

| 70 | Impact absorber for railroad cars | US3693768D | 1970-10-14 | US3693768A | 1972-09-26 | ERDMANN HANS |
| A railroad car impact absorber having a fluid filled cylinder with a matching piston movable in the cylinder to force fluid through an orifice in the piston, the area of the orifice varying with the piston position by means of a grooved throttle rod attached to the cylinder and extending into the orifice. A floating piston in the chamber on the other side of the piston forms a gas return spring. The throttle rod causes a lower deceleration during the first part of the piston displacement than during the second part of the displacement.

| A vehicle body is disclosed having a floor and a pair of upstanding support members spaced apart in the direction of travel of the vehicle. Bands of strapping material are extended longitudinally in the body and have their opposite ends secured to the upstanding support members at points spaced above the floor, so that intermediate portions of the bands rest on the floor and their end portions slope upwardly toward the support members. A unitized load is placed on the intermediate portions of the bands and is spaced from the support members by the sloping band end portions, whereby upon impact the load may ride up the strap members to absorb impact energy.
