Abstract: A vertical tensioning means and a horizontal tensioning means for a curtained door of a van body. The vertical tensioning means comprises at least one set of rollers which are rollably movable in each of upper and lower tracks located opposite the top and bottom of the van body. The vertical tensioning means also includes adjustable straps which communicate with upper and lower brackets which hold the rollers.The horizontal tensioning means comprises an end plate which includes a cam keeper portion capable of being engaged by a cam. The curtain of the door is bossed against the end plate. Horizontal tensioning of the curtain is provided when the cam engages the end plate.

Abstract: A method of preparing truck floor boards of a desired standard length from floor boards having differing, initial standard lengths. For the case wherein the desired standard length is less than initial standard length, one may begin with severing, by saw-cutting, from a board having at least one initial standard length, as many desired length-boards as are available; this leaves a remainder board. One may also begin with such a remainder board, as an end product of a previous execution of the method, or of a cycle of the method. A finger joint profile is cut in the trailing end surface of the remainder board, and a mating finger joint profile is cut into the leading end surface of an initial-standard-length board. By gluing, the finger jointing is completed, and from the resultant composite board, severed out by saw-cut are as many desired length boards as are available. This may leave a new remainder board of sufficient length to warrant its inclusion in a new cycle of the method.

Abstract: A ramp for trucks and the like is disclosed for use with a truck body, which includes parallel spaced rails extending longitudinally of the truck, secured to the truck chassis, of the I-beam type, carrying at least one trolley which is movable longitudinally in a track formed by the rails, which supports a carriage which is connected to side frame bars which are pivotally connected to the ramp, the carriage being positioned when the forward end of the ramp exits the truck body, so as to assist hooks on the forward end of the ramp to engage in openings in the truck body, while the rear end of the ramp rests on the ground.

Abstract: An air cargo container is disclosed of metallic construction which is light in weight, yet sturdy and which has structure for overcoming problems which have been encountered with cargo containers heretofore available and with particular reference to hold-down or restraint pockets, fork lift pockets and floor construction and which complies with present government and other applicable standards.

Abstract: A ramp and ramp carrier for trucks and the like is disclosed in which the truck body is provided with long rails comprising channels facing inwardly and which carry the cross members and truck floor, the long rails being supported and secured to the spaced parallel truck frame rails, with interposed spacers of wood, the securing elements being exteriorly of the channels and truck frame to avoid interior interference with the ramp, the ramp being carried between and by the long rails with provisions for retention and, upon withdrawal for use, with the outer end on the ground having members for hooking over a rear plate on the body.

Abstract: A transverse interlock floor for the bodies of trucks, vans, trailers and other vehicles is disclosed in which extruded transverse floor panels are employed extending from side to side in the body with edge interlocks between adjoining panels, and with stiffening braces on the undersides of the panels, the panels being secured to and supported from below on transverse I-beams of the body and with intermediate stiffening braces if desired, the transverse I-beams being supported on the longitudinal I-beams or frame members of the body which latter are secured to the longitudinal frame channels of the truck chassis.

Abstract: Heavy duty stake rack connectors for joining of racks for flat bed trucks and trailers which racks have upright portions engaged in hollow sockets of the truck or trailer bed are provided. The connectors may be formed as extrusions and operate as pairs of male and female connectors one at each end of the rack. The female connectors have U-shaped portions for the reception of vertical ribs from male connectors. Both connectors are symmetrical which avoids the necessity for right and left hand connectors. If desired, a portion of the male connector may be removed to provide a hinge pin on one side and a like portion of female connector at the opposite end of the racks removed permitting the rack to be swung away from an adjacent rack after vertical displacement and disengagement of its uprights from their sockets. The racks can be of picket or solid wall construction.
