Abstract: An energy-absorbing trailer hitch assembly is provided that includes a receiver tube and an insertion tube. The receiver tube is typically fixedly attached to a motor vehicle and has a set of apertures that affords for a pin to pass therethrough. The tube also has a set of slots adjacent to the apertures, with protrusions between each aperture and its adjacent slot. The insertion tube serves as a trailer hitch and has a set of apertures that align with the set of apertures in the receiver tube. Placement of the insertion tube within the receiver tube affords for a pin to pass through and be held within said apertures. In this manner a trailer may be attached to the trailer hitch and pulled by the motor vehicle. When the trailer is impacted, for example by a rear-end collision, deformation of the pin and/or the protrusions of the receiver tube allow the pin to travel in a forward direction, thereby absorbing energy from the collision.

When the receiver is moved in a first tow direction, the energy management device is isolated and the tow force is coupled directly to the frame. However, when the energy management device is moved in a second, generally opposite direction, the energy management device reduces some or all of the force applied to the receiver from being transferred to the vehicle frame.

Abstract: Impact attenuating devices (1) for vehicles (5) with frame side members (9) are used in e.g. roadwork areas to protect road-users, men at work and equipment. The attenuator (1) is connected at the rear or front end of a vehicle (5) which is placed behind or in front of a roadwork. A vehicle having not noticed the roadwork runs into the attenuator (1) which catches the vehicle. To be able to attenuate the great forces arising in collisions, the attenuator (1) must be long and fixedly connected to the vehicle (5). This makes it difficult to transport, and a long overhang easily sweeps outside the own lane when driving through curves. The object of the invention is to provide an attenuator (1) which is easy to transport between the roadwork areas. A vehicle (5), usually a lorry, with frame side members (9) is connected to an attenuator (1) comprising an attenuating part (3), wheels (4) and a connecting part (2).

Abstract: A trailer hitch uses a draw bar to interconnect tractor and trailer vehicles. The draw bar includes an elongated shank with a transverse throughway. A resilient cushion is disposed in the throughway. A passageway is associated with the throughway to receive a hitch pin such that longitudinal motion of the shank is resiliently resisted by the cushion. The cushion may be disposed in a rigid casing to form a cartridge that inserts into the throughway, and the passageway may be provided by a reciprocating slide member in the casing. Cushions may be employed in the casing to resist motion during both braking and acceleration. Cartridges having differing performance may be interchanged in the system. A method employing such structures is described.

Abstract: A sod cutting device having a pair of sod cutting blades offset such that their interior ends are aligned in the direction of cutting. Two strips of sod may thus be cut simultaneously with minimal waste. The two cutting blades are connected to inidividual cutter frames which are pivotably connected to respective lateral ends of a pivot frame. The pivot frame is in turn pivotably mounted at its center to a main frame of the device. This allows each cutter frame to follow the contours of the land and thus improves cutting depth consistency. The cut sod is conveyed up a first conveyor to a second conveyor which is mounted behind the first conveyor. A netting is introduced between the two conveyors under the sod such that the sod, together with the netting thereunder, travels up the second conveyor. The sod and netting are then rolled about a mandrel with the netting supporting the delicate sod. When a sod roll of sufficient size has been formed, the second conveyor is pivoted downwardly about its forward end.

Abstract: A laterally yieldable or "bendable" hitch pole is provided for the steering mechanism of a trailing vehicle to minimize or prevent breakage of the hitch pole during sharp turns negotiated by the draft vehicle, especially during backing of the trailer. The invention is especially applicable to trailers having steering mechanisms of the Ackerman type. The hitch pole is typically swingable between right and left stops and breakage or other damage occurs when the pole encounters one or the other of the stops and turning forces are still applied. The invention provides a two-piece hitch pole having its end-to-end parts connected in such manner as to enable "bending" of the hitch pole in those situations with subsequent recovery of the pole to its normal attitude.

Abstract: An A-frame trailer front end construction configured to alternately accept non-dampered connector for co-action with the towing vehicle or a damped connector without structural modification of the A-frame. Switch over between the damped and non-damped towing modes can be accomplished very quickly by the loosening and unloosening of mounting bolts between the connector and A-frame. The system enables the human operator to select the type of connection most conducive to human driver comfort, minimum inertial loading between the towed and towing vehicle, and lessened load forces on the vehicle brakes and suspension.
