Abstract
Abstract A track of a track laying vehicle consists of a set of identical track elements which are serially connected together by wire rope connectors extending between adjacent elements. An elastomeric seal protectively and supportably encloses portions of the wire rope connectors between opposing side edges of the adjacent track elements. The track elements are kept in alignment by gear teeth provided on each element and received in sockets formed in the adjacent element. The sockets have elastomeric inserts, portions of which serve to seal the space between the opposing side edges of the adjacent elements. Each track element is formed from two complemental parts which are separably secured together and are complementally recessed to accommodate the wire rope connectors.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
200 words
A track for a track laying vehicle, comprising a set of identical track elements serially connected together, each of said track elements having its ends at the sides of the track and also having side edges extending transversely of the track, opposing side edges of every two adjacent elements in the set being spaced away from each other, a plurality of wire rope connectors connecting together every two adjacent elements, said rope connectors having their ends anchored in the respective adjacent elements and extending through the space between said opposing edges of the adjacent elements, an elastomeric seal disposed in the space between every two adjacent elements, said seal protectively and supportable enclosing said plurality of rope connectors, and aligning means provided at the end portions of every two adjacent track elements and cooperating to prevent movement thereof relative to each other transversely of the track, said aligning means comprising a gear tooth provided on each end portion of each track element and received in a socket provided in each end portion of the adjacent track element, and an elastomeric insert provided in the socket of each track element and receiving said gear tooth of the adjacent track element therein.
Claim 2
Dependent Claim
200 words
A track for a track laying vehicle, comprising a set of identical track elements serially connected together, each of said track elements having its ends at the sides of the track and also having side edges extending transversely of the track, opposing side edges of every two adjacent elements in the set being spaced away from each other, a plurality of wire rope connectors connecting together every two adjacent elements, said rope connectors having their ends anchored in the respective adjacent elements and extending through the space between said opposing edges of the adjacent elements, an elastomeric seal disposed in the space between every two adjacent elements, said seal protectively and supportable enclosing said plurality of rope connectors, and aligning means provided at the end portions of every two adjacent track elements and cooperating to prevent movement thereof relative to each other transversely of the track, said aligning means comprising a gear tooth provided on each end portion of each track element and received in a socket provided in each end portion of the adjacent track element, and an elastomeric insert provided in the socket of each track element and receiving said gear tooth of the adjacent track element therein.
Claim 3
Dependent Claim
33 words
The device as defined in claim 1 wherein said elastomeric insert includes an outer portion projecting from said socket and sealing the space between said opposing side edges of the adjacent track elements.
Claim 4
Dependent Claim
161 words
A track element for a track laying vehicle wherein a set of identical track elements are serially connected together to form the track, said track element having ends at the sides of the track and also having side edges extending transversely of the track, and aligning means on said track element for aligning the same with respect to adjacent track elements, said aligning means comprising a gear tooth projecting from one side edge of an end portion of said element, the other side edge of said end portion being provided with a socket for reception of a gear tooth of an adjacent track element whereby to prevent relative movement of adjacent elements transversely of the track, and a tooth-receiving insert of elastomeric material provided in said socket, said elastomeric insert including an outer portion projecting from said socket to seal a space between the side edge of the associated track element and an opposing side edge of an adjacent track element.
Claim 5
Dependent Claim
161 words
A track element for a track laying vehicle wherein a set of identical track elements are serially connected together to form the track, said track element having ends at the sides of the track and also having side edges extending transversely of the track, and aligning means on said track element for aligning the same with respect to adjacent track elements, said aligning means comprising a gear tooth projecting from one side edge of an end portion of said element, the other side edge of said end portion being provided with a socket for reception of a gear tooth of an adjacent track element whereby to prevent relative movement of adjacent elements transversely of the track, and a tooth-receiving insert of elastomeric material provided in said socket, said elastomeric insert including an outer portion projecting from said socket to seal a space between the side edge of the associated track element and an opposing side edge of an adjacent track element.
Claim 6
Dependent Claim
22 words
The device as defined in claim 3 wherein said track element comprises a pair of complemental superposed plate members separably secured together.
Claim 7
Dependent Claim
105 words
The device as defined in claim 3 wherein said track element comprises a pair of complemental superposed plate members separably secured together, together with flexible means connecting said track Element to an adjacent track element, said connecting means comprising a plurality of wire rope connectors with enlarged heads at each end thereof, said complemental plate members of the track element being recessed so as to form in the assembled track element a cavity in which said heads are disposed and ducts extending from said cavity to one side edge of the plate member through which ducts said rope connectors extend toward an adjacent track element.
Claim 8
Dependent Claim
38 words
The device as defined in claim 5 together with an elastomeric seal positionable on said rope connectors between adjacent track elements to protectively and supportably enclose portions of the rope connectors between opposing side edges of adjacent elements.
Claim 9
Dependent Claim
39 words
The device as defined in claim 3 together with a pair of spaced ribs extending transversely at the underside of said track element, said element being provided with sprocket tooth receiving apertures communicating with the space between said ribs.
