Abstract
Abstract A tilt cab is mounted at one end of a vehicle for downward tilting movement around a pivot axis and subsequent support on a lift member associated with the vehicle. A load damping and energy storing device is connected between the cab and the frame of the vehicle in such a manner as to be activated by upward movement of the lift member conjointly with the downward swinging of the tilt cab, to first dampen the movement of the tilt cab downwardly while simultaneously being loaded and thereafter exerting a hold-down force on said tilt cab to maintain secure shake-proof support of the cab on the lift member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
252 words
In combination with a vehicle having a chassis including an operator station and a tilting cab normally enclosing said operator station and pivotally movable between a normal enclosing position and a transport position remote from said operator station; characterized by first support means for said tilt cab associated with said vehicle and pivotally attached to said chassis for movement between a lowered and a raised position; a pivot shaft supported for rotation on said chassis for connection of said tilt cab to said chassis; a first lever attached to said pivot shaft; a second lever attached to said pivot shaft in angular offset position relative to said first lever; linkage means between said first lever and said first support means; second support means for said tilt cab attached to aid chassis; means operatively connecting said second support means with said second lever; actuator means for raising of said first support means towards said tilting cab; said second support means comprising an energy storing and load supporting device; said first support means upon actuation by said actuator means being effective to rotate said pivot shaft by means of said first lever and said linkage means to tilt said cab forwardly towards said first support means and simultaneously activated said second support means by means of said second lever connected to said pivot shaft whereby said energy storing and load supporting device of said second support means is effective to maintain said tilt cab in substantially rigid rest position upon said first support means.
Claim 2
Dependent Claim
252 words
In combination with a vehicle having a chassis including an operator station and a tilting cab normally enclosing said operator station and pivotally movable between a normal enclosing position and a transport position remote from said operator station; characterized by first support means for said tilt cab associated with said vehicle and pivotally attached to said chassis for movement between a lowered and a raised position; a pivot shaft supported for rotation on said chassis for connection of said tilt cab to said chassis; a first lever attached to said pivot shaft; a second lever attached to said pivot shaft in angular offset position relative to said first lever; linkage means between said first lever and said first support means; second support means for said tilt cab attached to aid chassis; means operatively connecting said second support means with said second lever; actuator means for raising of said first support means towards said tilting cab; said second support means comprising an energy storing and load supporting device; said first support means upon actuation by said actuator means being effective to rotate said pivot shaft by means of said first lever and said linkage means to tilt said cab forwardly towards said first support means and simultaneously activated said second support means by means of said second lever connected to said pivot shaft whereby said energy storing and load supporting device of said second support means is effective to maintain said tilt cab in substantially rigid rest position upon said first support means.
Claim 3
Dependent Claim
24 words
The combination as defined in claim 1, characterized by provision of anti-friction means for support of said tilt cab upon said first support means.
Claim 4
Dependent Claim
144 words
The combination as defined in claim 1, further characterized by a pivot block attached to said chassis rearwardly of said pivot shaft; said means connecting said second support means with said second lever comprising a rod pivotally attached to said lever and slidingly supported within said pivot block; said energy storing and load supporting device of said second support means comprising spring means associated with said rod; the axis of said pivot shaft and said pivot block defining a dead center; said spring means being normally in unloaded condition with said cab is in normal enclosing position whereby upon actuation of said first support means said spring means will be gradually compressed and moved through said dead center to thereby exert a downward clamping force of predetermined magnitude on said cab to maintain substantially rigid engagement between said first support means and said cab.
Claim 5
Dependent Claim
135 words
In a vehicle, a frame, a tilt cab mounted for tilting movement thereon; cab tilting means connected to said frame and said cab for movement of said cab between a raised and a lowered position; characterized by load absorbing energy storing means; actuator means for actuating said tilting means and said load absorbing energy storing means; said load absorbing energy storing means including an overcenter linkage and at least one spring operatively connected between said cab and said frame so that upon activation of said tilting means said cab will be caused to tilt to said lowered position and said load absorbing energy storing means will first absorb load during movement of said cab towards said lowered position and thereafter will exert said load on said cab to maintain said cab in said lowered position.
Claim 6
Dependent Claim
135 words
In a vehicle, a frame, a tilt cab mounted for tilting movement thereon; cab tilting means connected to said frame and said cab for movement of said cab between a raised and a lowered position; characterized by load absorbing energy storing means; actuator means for actuating said tilting means and said load absorbing energy storing means; said load absorbing energy storing means including an overcenter linkage and at least one spring operatively connected between said cab and said frame so that upon activation of said tilting means said cab will be caused to tilt to said lowered position and said load absorbing energy storing means will first absorb load during movement of said cab towards said lowered position and thereafter will exert said load on said cab to maintain said cab in said lowered position.
Claim 7
Dependent Claim
42 words
The tilt cab mechanism of claim 4 characterized by said cab tilting means comprising a support member mounted for pivotal movement towards said cab as the latter tilts towards said lowered position for supporting engagement with said cab in said lowered position.
Claim 8
Dependent Claim
23 words
The tilt cab mechanism of claim 5 characterizEd in that said vehicle comprises a combine and said cab tilting means comprises an elevator.
