Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
144 words
In a stationary hoist for a vehicle having wheels and a frame, a wheel carrier having means for disengageably engaging said vehicle by its wheels to be lifted and lowered by and with said wheel carrier; a lift reciprocable between an elevated and a lowered position; a frame carrier attached to said lift having means for disengageably engaging the vehicle by its frame to be lifted and lowered by and with said frame carrier; linkage operable to couple said wheel carrier to said lift enabling the lift to raise and lower the wheel carrier and the vehicle engaged thereby when reciprocated as aforesaid; mans for supporting said wheel carrier and vehicle at an elevated position independently of said lift; said linkage being also operable to de-couple said wheel carrier from said lift enabling the lift to reciprocate as aforesaid independently of said wheel carrier.
Claim 2
Dependent Claim
144 words
In a stationary hoist for a vehicle having wheels and a frame, a wheel carrier having means for disengageably engaging said vehicle by its wheels to be lifted and lowered by and with said wheel carrier; a lift reciprocable between an elevated and a lowered position; a frame carrier attached to said lift having means for disengageably engaging the vehicle by its frame to be lifted and lowered by and with said frame carrier; linkage operable to couple said wheel carrier to said lift enabling the lift to raise and lower the wheel carrier and the vehicle engaged thereby when reciprocated as aforesaid; mans for supporting said wheel carrier and vehicle at an elevated position independently of said lift; said linkage being also operable to de-couple said wheel carrier from said lift enabling the lift to reciprocate as aforesaid independently of said wheel carrier.
Claim 3
Dependent Claim
26 words
A stationary hoist for a vehicle as set forth in claim 1 wherein: the means for disengageably engaging said vehicle by its wheels consist of runways.
Claim 4
Dependent Claim
30 words
A stationary hoist for a vehicle as set forth in claim 2 wherein: the runways are spaced to permit access to the bottom of the vehicle while supported as aforesaid.
Claim 5
Dependent Claim
20 words
A stationary hoist for a vehicle as set forth in claim 2 wherein: said lift is positioned between the runways.
Claim 6
Dependent Claim
32 words
A stationary hoist for a vehicle as set forth in claim 4 wherein: the linkage operates between said lift and said runways to couple and de-couple the lift and said wheel carrier.
Claim 7
Dependent Claim
53 words
A stationary hoist for a vehicle as set forth in claim 4 including: crossbeams joining the runways, and bars interconnecting said crossbeams between the runways; said bars forming part of the linkage aforesaid and beIng movable while connected to said crossbeams to couple and de-couple the wheel carrier to and from said lift.
Claim 8
Dependent Claim
39 words
A stationary hoist for a vehicle as set forth in claim 6 including: cantilever facilities securing said bars to said runways; the cantilever facilities being extendible and retractable to couple and de-couple the lift and wheel carrier as aforesaid.
Claim 9
Dependent Claim
32 words
A stationary hoist for a vehicle as set forth in claim 7 wherein: said cantilever facilities include piston-cylinder motor means for effecting coupling and decoupling of the said lift and wheel carrier.
Claim 10
Dependent Claim
48 words
A stationary hoist for a vehicle as set forth in claim 2 wherein: the vehicle frame engaging means on said frame carrier comprise arms by which the vehicle frame is engageable as aforesaid and which are foldable to be disposed and to lie wholly between the two runways.
Claim 11
Dependent Claim
57 words
A stationary hoist for a vehicle as set forth in claim 2 wherein: said lift is disposed between the runways; said frame carrier is permanently mounted on said lift and co-movable therewith, and said linkage is constituted by tongues mounted on said lift; each said tongue being extendible and retractable to engage and disengage a said runway.
Claim 12
Dependent Claim
50 words
A stationary hoist for a vehicle as set forth in claim 9 wherein: said lift is disposed between the runways; said frame carrier is permanently mounted on said lift and co-movable therewith, and said arms also constitute linkage disengageably engageable with the wheel carrier for coupling it to the lift.
