Date Aug. 21, 1980 An adjustable double link mounting for interconnecting a pair of structures, such as structures (37, 51) mountable on a crawler vehicle (10), including at least a pair of spaced-apart lugs (44, 82, 83, 84, 85) on each of the structures and each having a bore, a pair of spaced-apart links (80,81) having a pivotal connection at each end to at least one lug as provided by a pin-receiving opening (91, 92, 105, 107) for receiving a pin (93, 94, 104, 106) which also extends through an apertured lug, and one (81) of the links including a turnbuckle (110, 111, 112) for adjusting the effective length thereof.

Adjustable double link mounting

A vehicle has elements providing a fluid pathway to the controlling system of spring actuated, normally locked brakes that are fluid releasable. The elements forming the fluid pathway are connectable to a fluid power assembly that is movable to and from the vehicle and releasably connected to the fluid pathway.

Vehicle having portable power means for brake control

Structure for removably locking a cover in a covering disposition. The locking device is arranged to be released notwithstanding the disposition thereof in a relatively inaccessible area of the machine on which the cover is mounted. The locking device includes a locking pin which is axially movable so as to have clearance with the cover with the pin being so moved by a tool inserted through the small access space available to the locking device. The pin is drawn back outwardly into locking arrangement with the cover by a threaded device having a shank portion passed through a hole in the cover into threaded association with the locking pin, permitting threaded operation of the device to draw the pin outwardly into the hole of the cover and thereby lock the cover against rotation about a pivot mount thereof.
