Abstract: An all terrain vehicle has two vehicle units and an articulating link which interconnects the vehicle units in tandem. Each vehicle unit has a body and a pair of spaced crawler tracks which are powered for moving the respective vehicle unit. The articulating link has two longitudinally spaced apart pitch hinge assemblies, each of which cooperates with a respective vehicle unit to permit relative rotation therebetween about a horizontal pitch axis without interference between the vehicle units. Pitch swivelling means associated with one particular pitch hinge assembly can force relative rotation about the particular pitch axis between a particular vehicle unit and the link, so that one vehicle unit can be rotated forcibly relative to the other vehicle unit to negotiate marginal terrain. The remaining pitch hinge assembly can be either freely hinged to permit rotation about the remaining pitch axis or alternatively can have a similar pitch swivelling means.

Abstract: A safety hauling coupler characterized by comprising a buffer tube with a spring fitted there-over and a slot made therein, two extension tubes respectively fitted over and fixed to one end of the buffer tube by means of retaining pins, two connecting tubes respectively fitted in and fixed to the extension tubes at one end and hauling hooked heads at the other, two sleeves respectively fitted over the connecting tubes, two wire cables to be held by the hooks and attached to the supports of vehicles, and six retaining pin for fixing the said tubes, so that it can firmly join the hauling vehicle and that to be hauled and prevent the hauling vehicle from being hit by the hauled vehicle.

Abstract: An articulated vehicle for carrying cargo. The vehicle includes a truck in the form of a tractor having a cab mounted on a chassis and supported on small diameter wheels. A first body is releasably, but stationarily, secured to the chassis by an elevatable fifth wheel assembly. A trailer, which is mounted on identical diameter wheels, is connected to the truck body, via a tow bar-pintle hook connection. The connection is located approximately 8 feet (2.44 m) forward of the end of the truck body. The trailer is separated from the truck body by approximately 1 foot (30.5 cm) so that it is enabled to pivot with respect to the truck through a long swing angle to enable the vehicle to safely negotiate corners and curves. The fifth wheel assembly is elevatable to enable the tractor, when the body is removed therefrom, to be used with conventional trailers.

Abstract: A tow bar coupling head removably attachable to the cross pin of an aircraft nose wheel strut has a solid metal body portion with a transverse slot in its underside within which the cross pin is received. A positive deadbolt slide lock retains the cross pin in place. A removable locking pin extending vertically through the body portion prevents accidental withdrawal of the deadbolt slide lock.

Abstract: A towbar assembly wherein two individual towbars are arranged in a V-configuration between a towing vehicle and a towed vehicle. The leading ends of the towbars have special end connectors that hook around a single towing pintle so that each towbar carries approximately the same tensile loading irrespective of changes in vehicle pitch or roll attitude. Each towbar is essentially independent of the other towbar, whereby the towbar loadings are essentially in the direction of the bar longitudinal axis; bending forces are to a great extent eliminated. The invention is designed primarily for use in towing large heavy vehicles weighing in excess of fifty tons.

Abstract: A folding trailer is provided having a chassis supported by at least one pair of road wheels and a load bearing platform supported by the chassis, the load bearing platform being formed in two sections which are foldable between a first position in which the sections lie in a common plane and a second position in which the sections lie juxtaposed in parallel planes. When in the second position the trailer can be moved into a substantially vertical plane for stowage.

Abstract: This invention relates to a towbar particularly adapted for attachment to a snowmobile for towing the snowmobile. The towbar includes an elongated tubular tongue with a hitch connected to one end for releasably securing the tongue to a rear hitch on a snowmobile. An elongated tubular crossbar is fixed to the other end of the tongue. The crossbar is adapted for releasable connection to runners of a snowmobile which is to be towed. An elongated ear is connected to each end of the crossbar for holding the towbar onto the runner. Each ear has one end fixed to the crossbar and the other end spaced away from the crossbar and extending toward the other ear for receiving a portion of a runner between the ear and the crossbar for holding the runner in connection with the towbar.

Abstract: A hitch for connecting a prime mover such as a tractor to an implement such as a plough to be drawn by the prime mover. The hitch comprises a two part prime mover drawbar and a separate single part implement drawbar. One part of the prime mover drawbar is connectable to the prime mover, the other part carries a spring loaded first latch, the implement drawbar carries a second latch, the first and second latches being arranged to secure the prime mover drawbar and the implement drawbar.

Abstract: A multi-purpose four-wheel drive vehicle having four-wheel steering. The vehicle according to the present invention incorporates a number of features, some of which are individually known in the prior art but which, when combined in a single vehicle, constitute a vehicle having several advantages over conventional vehicles presently employed for various uses. The applicant's multi-purpose vehicle is of light-weight construction, is relatively inexpensive to manufacture in comparison with vehicles presently employed for the same jobs as those accomplished by the present vehicle, and has substantially less initial and operating costs. The applicant's vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four corners of a main frame body of the vehicle.

Abstract: A strut for MacPherson-type suspensions for motor-vehicles comprises an upper tubular member of sheet metal which forms the cylinder of a telescopic shock absorber, and a sheet metal housing having an upper wall with a circular aperture. An additional reinforcing member of sheet metal is welded to the housing to define a supplementary wall adjacent to the upper wall of the housing. The supplementary wall has a circular aperture, aligned with, and spaced from, the circular aperture of the upper wall. A lower portion of the tubular member is engaged with a close fit into the said two aligned apertures and is fixed by welding to an edge of at least one of the apertures.

Abstract: A trailer has a platform whose center of gravity may be placed forward or rearward of its support. When the center of gravity is in the rearward position the platform is enabled to tilt its rear end to the ground to facilitate loading or unloading. A cable arrangement pulls the load up the sloping platform onto the platform. The center of gravity is positioned forward of the support to travel.

Abstract: A tow bar assembly including a pair of draft bars, attachment members for the bumper of a towed vehicle, universally coupled to the trailing ends of the tow bars, and a towing vehicle coupling member pivotally joined to the leading ends of the tow bars, to permit pivotal adjustable movement of the draft bars in a substantially horizontal plane.
