Abstract: A track assembly for endless track vehicles is disclosed utilizing endless, elastomeric-sheathed, elastomer-impregnated glass fiber cable structures on which are strung individual track sections composed of a lug unit and a shoe plate unit. Each of the lug units includes passageways extending transversely of the length dimension thereof for receiving the continuous sheathed cable structures. The lug units are held in spaced apart relation from each other by integral, regularly spaced elastomeric projections extending laterally from the sides of the cable structures. The shoe plate units are secured to each of the lug units and hold the sheathed cable structures in position in the passageways without substantial compressive loading of the cable structures. The elastomeric sheath is bonded to the elastomer impregnated cables, substantially eliminating relative movement between the cables and the surrounding sheath. A load exerted on any individual track section by the drive sprocket of the track vehicle is shared with the adjacent track sections. Movement between the track sections is limited to that within the elastic limit and below the tear limit of the sheath and cables embedded in the sheath. Each of the lug units is provided with means forming a mechanical stop which prevents flexing of the cables beyond their elastic limit and means for engaging the drive sprocket of the vehicle through which vehicle drive forces are transmitted to the track assembly. Integral rails projecting from each of the lug units transversely of their length dimension and substantially parallel to the passageways for the cable structures extend beyond the opposite sides of the lug units and are engageable with the rails of adjacent lug units to limit lateral movement of the track sections relative to each other.

Abstract: A coreless glass fiber cable is made of a plurality of individual substantially untwisted glass fiber rovings twisted together. Prior to twisting but during the twisting operation certain of the rovings are impregnated with one component of an elastomeric resin with the remainder of the rovings impregnated with the second component of the elastomeric resin. The impregnated rovings are spirally twisted together in the same direction at substantially the same helical angle, the two components of the elastomeric resin impregnating the rovings mixing with each other at the junction of the intertwining of the rovings to form a cured elastomer spacing the glass fiber rovings and filaments making up the rovings from each other. The layed up glass fiber cable is fed back on itself and subsequent layers of impregnated rovings plied together over the initial layers. The subsequently applied layers are applied at the same helical angle as the initial layer. The cable, although useful for other purposes, is particularly useful in the manufacture of endless track for track vehicles, the endless track comprising a plurality of individual track sections strung along a cable of the type mentioned.

Abstract: A deflector of a sheet distributing mechanism is positioned at selected sheet-receivers or stations in response to the passage of sheets past the deflector. A manually programmed crossbar switch determines the preselected numbers of sheets to be distributed to any one of several sheet-receivers. A sheet stepping switch and a station stepping switch join the programmed crossbars of the crossbar switch when the programmed number of sheets have been received at the selected sheet-receiver so as to index the deflector to the next sheet-receiver. The number of sheets and the number of sheet-receivers programmed may be varied, sheet-receivers may be skipped or the device may operate as a collator by distributing a single sheet at a time to one or more of the sheet-receivers. An anticipating device is employed on the station stepping switch to permit smooth operation of the distributing mechanism when several sheet-receivers are to be skipped.
