Abstract
Abstract A cab-over-engine automotive truck cab is provided with a two-piece transmission shift handle. A telescopic sleeve holds the two shift handle sections together against relative lateral movement and the sleeve can be moved against the pressure of a spring to release the remote section so that it may pivotally break over at an angle to the lower section. In this manner, a slot in the floor of the cab can clear the upper shift handle section whereas without break over the shift handle would not allow adequate clearance with movement of the floor about a forward pivot axis.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A break-over shift lever assembly for cab-over-engine automotive trucks wherein the entire cab including a floor pivots about a forward pivot axis to expose the engine beneath the cab, comprising: a transmission shift assembly having a two-piece shift handle connected below the cab floor to shift linkages and movable between fore and aft and lateral positions to operate the shift linkages, said floor having a slot with said shift handle extending upwardly above the slot but in an interference location with the path of the floor as the floor is swung about the forward pivot axis, and means for releasibly breaking the two-piece shift handle into an upper lever section and a lower lever section while still connected together with the juncture between the two sections lying below the path of movement of the floor whereby the cab is pivoted over the shift handle.
Claim 2
Dependent Claim
144 words
A break-over shift lever assembly for cab-over-engine automotive trucks wherein the entire cab including a floor pivots about a forward pivot axis to expose the engine beneath the cab, comprising: a transmission shift assembly having a two-piece shift handle connected below the cab floor to shift linkages and movable between fore and aft and lateral positions to operate the shift linkages, said floor having a slot with said shift handle extending upwardly above the slot but in an interference location with the path of the floor as the floor is swung about the forward pivot axis, and means for releasibly breaking the two-piece shift handle into an upper lever section and a lower lever section while still connected together with the juncture between the two sections lying below the path of movement of the floor whereby the cab is pivoted over the shift handle.
Claim 3
Dependent Claim
67 words
The assembly of claim 1, said releasible breaking means including a sleeve telescopically mounted on one of the shift lever sections and extendable telescopically over the other shift lever section to lock the two sections together against relative lateral movement, means pivotally interconnecting the two sections, means for biasing the sleeve into its locking position and means for guiding said other shift lever section into the sleeve.
Claim 4
Dependent Claim
115 words
The assembly of claim 2, said sleeve being telescopically attached to the upper shift lever assembly, said guiding means for said other shift lever assembly including a chamfered plug attached to the lower shift lever section, said sleeve having a lower end with a similarly chamfered end for receiving the plug and cam surfaces on said end of the lower shift lever section for assisting in guiding the plug into the sleeve and for holding the sections in a break-over condition wherein upward movement of the sleeve will break over the shift lever sections and alignment of the sleeve over the lower shift lever section will automatically restore the sleeve to its extended, locking position.
