Abstract: A track-over-tire driving arrangement comprises a pneumatic tire having a plurality of equally spaced notches formed on the periphery thereof. An endless track assembly, completely wrapped around the tire, comprises a plurality of closely coupled groundengaging track shoes connected together by an annular articulated link assembly positioned on each side of the tire. A common pivot means pivotally connects laterally opposed pairs of links of the link assemblies together and is totally confined within a respective one of the notches for providing a mechanical drive connection between the tire and track assembly.

Abstract: A pair of tractors are disposed in side-by-side relationship and are coupled together for unitized operation by front, rear and diagonal cross bracing which provides for a limited amount of transverse and longitudinal oscillation of either tractor relative to the other. The rear cross brace structure is defined in part by ripper tooth-mounting members in an arrangement which does not block the independent oscillation of either tractor.

Abstract: Lubricating means are provided for lubricating track rollers for track-type vehicles including conventional support bushing bolt holes modified to communicate with existing lubricant reservoirs via radial passages formed between the bolt holes and the reservoirs. Removal of one of the bolts from the modified bolt hole and loosening of another such bolt pemits filling and venting of the corresponding reservoir for replenishing lubricant as necessary, either in the factory or field.

Abstract: A material transport vehicle is provided with a material stuffing mechanism for transferring material from a loading bin mounted ahead of a relatively large material receiving body carried on the rear end of the vehicle chassis. A pusher mechanism is reciprocably mounted within the body and includes a pair of pusher members pivotal to a first position providing an opening between such members to admit material from the loading bin into the body and to a second position to form a substantially continuous wall for compacting material within the body and subsequently ejecting it therefrom.

Abstract: A mining machine includes front and rear sections connected together for pivotal movement about a vertical axis. The front section is made up of a unitary frame which includes a lower frame portion, upwardly extending legs, and a roof portion. The roof portion defines an opening, and a door is associated therewith to selectively block and unblock such opening. A power unit is associated with the rear section, and is easily detachable therefrom.

Abstract: An end loader in which the bucket operating linkage has lift arms that form a secondary boom pivoted on the frame, lifting jacks to control the position of the secondary boom, bell cranks fulcrumed at the free ends of the lift arms which have first arms forming a primary boom and short second arms, the bucket having lower pivots by which it is carried on the primary boom and there being primary jacks pivoted to the frame and to the second bell crank arms to swing the primary boom on the secondary boom. Bucket aspect on the primary boom is controlled by control levers fulcrumed on the bell crank fulcrums, dumping jacks pivoted to first arms of the control levers and to upper bucket pivots, and tag links pivoted to short second arms of the control levers and to the primary jack pivots on the frame.

Abstract: Mounting brackets are retained within crawler tractor roller assemblies by bracket-retaining means including an obliquely fitted lock pin angled between the bracket and roller shaft; such bracket-retaining means are particularly useful in restraining individual mounting brackets from axial and rotary displacement during storage and handling of the asembly. Assembly bolts are retained within these mounting brackets by bolt-retaining means including an elastomeric retainer snugly fitted to the bolt and compressible into a subjacent shallow relief in the bracket during installation of the roller assembly in the tractor.

Abstract: A pneumatic tire or the like has a protective chain assembly wrapped therearound. The chain assembly comprises a plurality of rings coupled together by notched and co-planar cylindrical coupling means which also serve as tread sections on the periphery of the tire. Each coupling member attaches two of the rings together to form a tire chain assembly exhibiting multidirectional flexibility. In addition, the integrated chain assembly is reversible and the dimensions thereof may be selectively varied to provide various earthworking functions, such as compacting. In the preferred embodiment, one group of such coupling members forms master coupling members or joints for assembly and disassembly purposes.
