10. The tractor of claim 8 in which said towing mechanism is mounted on a side of said tractor for lateral extension and retraction relative to said side.
11. The tractor of claim 8 which includes a second said towing mechanism mounted on the other side of said tractor for selective extension and retraction relative to said other side, whereby said tractor may engage and tow a trailer from either side thereof.
12. The tractor of claim 8 in which said control means includes fluid valve structure for regulating a fluid cylinder to selectively effect extension, retraction, locking, or free movement of said framework relative to said tractor.
13. In combination, a trailer, and a tractor for towing said trailer from a side thereof; sAid trailer including towing structure mounted on the side frame of said trailer adjacent an end thereof; said tractor including towing mechanism mounted thereon comprising a selectively movable framework, a towing member connected with said framework and movable to an extended position in which it is interengageable with said towing structure on said trailer; means for effecting selective extension and retraction of said framework and said towing member therewith so that interengagement of said towing member with said trailer towing structure may be effected without manual intervention between the tractor and trailer; and control means for regulating the position of said framework relative to said tractor and said trailer; said tractor and trailer being operatively interengageable through said towing structure and said towing mechanism so that said trailer may be towed by said tractor from said side thereof.
14. The combination of claim 13 in which said trailer includes a plurality of said towing structures mounted thereon at spaced locations adjacent one or more ends thereof, whereby said trailer may be side towed by said tractor from more than one position.
15. The combination of claim 13 in which said trailer includes four of said towing structures mounted thereon, said towing structures being positioned adjacent opposite ends of said trailer and at opposite sides thereof.
16. The trailer of claim 15 in which the towing structures at opposite ends of said trailer on each side thereof are oppositely oriented relative to each other so that the guide ramps thereof extend toward each other.
17. The combination of claim 13 in which said towing structure of said trailer includes a socket to receive said towing member therein, and a guide ramp mounted on said trailer side frame adjacent said socket, said ramp having an inclined section which opens onto said socket so that engagement of said towing member on said tractor with said socket is facilitated.
18. The combination of claim 17 in which said towing member comprises an elongated rigid towing pin which is selectively receivable in said socket when said tractor and trailer are coupled for towing.
19. The combination of claim 13 in which said tractor includes a second said towing mechanism mounted on the other side of said tractor for selective extension and retraction relative to said other side, whereby said tractor may engage and tow a trailer from either side thereof.
20. The combination of claim 13 in which said towing mechanism includes control means for regulating the position of said framework, said control means comprising fluid valve structure for regulating a fluid cylinder to selectively effect extension, retraction, locking, or free movement of said framework relative to said tractor.
21. For use in combination with a tractor having towing mechanism mounted thereon which imparts side tow capability thereto, a double-ended towable trailer or like vehicle which is designed to be moved with either of its opposite ends leading and which may be coupled with or uncoupled from a tractor without manual intervention between said trailer and tractor to effect such coupling or uncoupling; said trailer including towing structure mounted on the side frame of said trailer adjacent each of the opposite ends thereof which is automatically engageable with a tractor without manual intervention, each said towing structure comprising a vertically oriented socket positioned to receive therein a member of the towing mechanism of said trailer, a guide ramp mounted on said trailer side frame adjacent said socket, said ramp having an upwardly inclined section which opens onto said socket so that engagement of said towing member on said tractor with said socket may be effected without manual intervention; so that towing of said trailer from either side thereof and in either direction may be effected upon movement of said tractor with said towing mechanism and one of said towing structures interengaged.
22. The trailer of claim 21 in which the towing structures at opposite ends of said trailer on each side thereof are oppositely oriented relative to each other so that the guide ramps thereof extend toward each other.
23. The trailer of claim 21 in which each of said sockets comprises a vertically extending cylindrical member which is hollow to receive a portion of the tractor towing mechanism therein, said cylindrical member including an extension thereof at its upper end having a cut out portion opening toward its associated guide ramp to further facilitate interengagement of said tractor towing mechanism with such socket without requiring manual intervention to effect such interengagement.
24. The trailer of claim 21 in which each said guide ramp includes sidewalls to prevent lateral separation of said towing mechanism of said tractor from said ramp during movement of said mechanism along said ramp as said mechanism and a socket are being interengaged.
25. For use in combination with a trailer having towing structure mounted thereon which imparts side tow capability thereto, a towing tractor having selectively extensible and retractable towing mechanism mounted on each side of said tractor for selective extension and retraction relative to an associated side whereby said tractor may engage and tow a trailer from either side thereof; each said mechanism comprising a selectively movable framework pivotally connected with a tractor side, a pivotal towing member hingedly connected with said framework and movable under the effects of gravity to an extended position in which it is interengageable with said trailer towing structure when said trailer is located adjacent such towing structure, means for effecting selective extension of said framework and said towing member therewith into engagement with said towing structure and for permitting vertical upward and downward movement of said framework relative to said towing structure when such interengagement is effected so that such towing member may be automatically engaged with a socket in said towing structure without requiring manual intervention to effect such interengagement, said means further effecting locking of said framework and said towing member in a fixed position upon interengagement of said towing member with said towing structure socket and for effecting selective retraction thereof from said socket without requiring manual intervention to effect such retraction; and manually actuatable control means for selectively regulating and position of said framework relative to said towing structure socket and for regulating the condition of said towing mechanism during coupling or uncoupling of said tractor with said trailer.
26. The tractor of claim 25 in which said control means includes a hydraulic fluid valve structure for regulating a fluid cylinder operatively interposed between said trailer and said framework to selectively effect extension, retraction, locking or free movement of said framework with said towing member thereon relative to said tractor.
27. The tractor of claim 25 in which said towing member comprises an elongated rigid pin pivotally mounted on said framework and movable under the effects of gravity to be selectively received within said towing structure socket on said trailer to be towed.
