Abstract: An aluminum chassis for road or railway vehicles is such that the transverse beams are continuous and are attached to the longitudinal beams by means of angle-pieces using threaded bolts and nuts or, in particular, parallelogram-shaped nuts. The transverse beams and, if desired, the longitudinal sections of the frame--which can also function as longitudinal beams--feature undercut channels in which the nuts engage. This type of construction offers various advantages that are realized in the assembly of the chassis and in repairing damaged vehicles.

Abstract: The invention pertains to a vehicle frame particularly suitable for use with fire truck aerial apparatus wherein the frame comprises a torque box highly resistant to twisting and deformation. The frame is of a box configuration, fully enclosed, wherein the bottom surface is inwardly recessed to provide clearance for the vehicle driveshaft, and to provide rigidity and resistance to twisting, internal K-bracing plates are welded to the lateral and bottom frame portions.

Abstract: A motor vehicle with axle pivot steering includes a rigid axle and a steering axle having swivelling wheels. The vehicle frame is made up of a first and a second frame portion each having longitudinally extending beams interconnected by transverse beams. First frame portion extends forwardly of the second frame portion and forms the front end of the frame. The second frame portion extends rearwardly of the first frame portion and forms the rear end of the frame. The longitudinal beams of the first frame portion are located inwardly of the longitudinal beams of the second frame portion and support the rigid axle and the steering axle. The rigid axle is located forwardly of the steering axle. The longitudinal beams in the front portion of the frame are at a level permitting easy access to the driver's seat.

Abstract: A framework structure including longerons and lateral ribs formed of relatively thin plate metal having bent-over long edges forming channels or Z-sections riveted and welded together forming a lattice type framework, as a supporting frame for a lightweight trailer construction. The frame construction includes channel-shaped struts or longerons and Z-shaped laterals and peripheral longerons.

Abstract: A shoulder belt carriage track extends longitudinally along the door window frame. The outboard shoulder belt end is attached to the window frame adjacent the rear end of the track and the inboard shoulder belt end is retractably mounted on the vehicle body inboard the occupant. A shoulder belt carriage is movable fore and aft along the track and slidably engages the shoulder belt. A rigid link has a rearward end pivotally connected to the carriage and a forward end mounted on the vehicle body. The fixed length of the rigid link is such that when the door is closed the carriage is established at the rear end of the track adjacent the end of the shoulder belt so that the shoulder belt is disposed in the normal diagonal position across the upper torso of the occupant. During door opening movement the link forcibly pulls the carriage forwardly to establish the shoulder belt in an occupant access position forwardly of the occupant.

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 vehicle frame has first and second members having adjustably telescoping channel portions securable by bolts disposed in selected combinations of holes provided in the channel portions for providing a total vehicle frame of a chosen length and wheelbase. Adjacent portions of the respective members define portions of a battery compartment which varies with the size of the vehicle frame to accommodate the power requirements thereof. Channel shaped spacers join facing portions of the members for increased strength of the resulting frame.A rear axle mounting assembly is adjustably mounted on the rear member for independent adjustment of the wheelbase.A second embodiment has front and rear members secured by a selected nestable spacer member having an adjustable axle mounting for independent adjustment of the vehicle frame and wheelbase.

Abstract: A vehicle frame having longitudinally spaced apart parallel tapered channel frame members extending forwardly from a unitized backhoe mounting rear frame section to a front yoke. The tapered channel frame members are narrow at the front yoke and become wider toward the midsection of the frame. These frame members are at their widest just forward of a rear axle location on the frame.A unitized backhoe mounting rear frame section and a loader tower locate the tapered channels relative to the longitudinal center line of the frame.
