Abstract
Abstract Frangible resilient shock absorbing supports are utilized for mounting an engine on the underside of the frame of a vehicle. Three vertical supports are provided to carry the weight of the engine, each vertical support including a resilient member which absorbs vibrations, and further including collapsable self sacrificing members which absorb a severe impact. A horizontal support stabilizes the engine in the fore and aft direction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
134 words
Mounting apparatus for supporting an engine from and below a frame of a vehicle, comprising a plurality of vertical supports, each vertical support being fastened to the engine and being adapted to be suspended from the vehicle frame, each of said vertical supports including rigid means preventing any substantial amount of movement of said engine at shock loads less than a severe impact but collapsing at shock loads above such a severe impact, and a horizontal support fastened to the engine and adapted to be fastened to the frame, said vertical supports being spaced around the center of gravity of the engine to substantially equally distribute the weight of the engine, and said horizontal support being sufficiently rigid in the horizontal fore and aft direction to prevent fore and aft swaying of the engine.
Claim 2
Dependent Claim
134 words
Mounting apparatus for supporting an engine from and below a frame of a vehicle, comprising a plurality of vertical supports, each vertical support being fastened to the engine and being adapted to be suspended from the vehicle frame, each of said vertical supports including rigid means preventing any substantial amount of movement of said engine at shock loads less than a severe impact but collapsing at shock loads above such a severe impact, and a horizontal support fastened to the engine and adapted to be fastened to the frame, said vertical supports being spaced around the center of gravity of the engine to substantially equally distribute the weight of the engine, and said horizontal support being sufficiently rigid in the horizontal fore and aft direction to prevent fore and aft swaying of the engine.
Claim 3
Dependent Claim
37 words
Apparatus as in claim 1, wherein each of said vertical supports comprises a pair of mounts, each of said mounts including said rigid means, the mounts of each pair being spaced in the fore and aft direction.
Claim 4
Dependent Claim
28 words
Apparatus as in claim 2, wherein each of said pair of mounts further includes a resilient member which provides isolation of vibration between said engine and said frame.
Claim 5
Dependent Claim
48 words
Apparatus as in claim 1, wherein said rigid means each include a tubular member extending between said frame and said engine, and a bolt extending through said tubular member and fastening said engine to said frame, said tubular member buckling and said bolt bending under a severe impact.
Claim 6
Dependent Claim
55 words
Apparatus as in claim 1, wherein said horizontal support is pivotally connected both to said engine and to said frame and extends in the fore and aft direction of said vehicle and is substantially rigid in the fore and aft direction, said horizontal support being laterally offset from the center of gravity of said engine.
Claim 7
Dependent Claim
96 words
Mounting apparatus for supporting an engine from and below a frame of a vehicle, comprising at least three vertical supports, each vertical support being fastened to the engine and being adapted to be secured to the vehicle frame, said vertical support being spaced around the center of gravity of the engine to substantially equally distribute the load, and each vertical support including a self sacrificing member which prevents any substantial movement of said engine at normal loads but which will collapse under unusually high shocks and absorb impacts, thereby protecting both the engine and the frame.
Claim 8
Dependent Claim
96 words
Mounting apparatus for supporting an engine from and below a frame of a vehicle, comprising at least three vertical supports, each vertical support being fastened to the engine and being adapted to be secured to the vehicle frame, said vertical support being spaced around the center of gravity of the engine to substantially equally distribute the load, and each vertical support including a self sacrificing member which prevents any substantial movement of said engine at normal loads but which will collapse under unusually high shocks and absorb impacts, thereby protecting both the engine and the frame.
Claim 9
Dependent Claim
23 words
Apparatus as in claim 6, wherein each of said vertical supports further includes a resilient member for isolating said engine from said frame.
Claim 10
Dependent Claim
26 words
Apparatus as in claim 6, wherein each of said vertical supports includes two mounts which are spaced in the fore and aft direction of said vehicle.
Claim 11
Dependent Claim
113 words
Mounting apparatus for supporting an engine from and below a mounting frame of a vehicle, comprising vertical support means fastened to the engine and being adapted to be secured to the vehicle frame, said vertical support means carrying the weight of said engine, and horizontal support means connected to said engine and being adapted to be connected to said frame forwardly of said engine, said horizontal support means being rigid in the horizontal fore and aft direction to prevent fore and aft swaying of the engine, but being pivotally connected to the engine and to the frame, and said horizontal support means being laterally displaced from the center of gravity of said engine.
Claim 12
Dependent Claim
113 words
Mounting apparatus for supporting an engine from and below a mounting frame of a vehicle, comprising vertical support means fastened to the engine and being adapted to be secured to the vehicle frame, said vertical support means carrying the weight of said engine, and horizontal support means connected to said engine and being adapted to be connected to said frame forwardly of said engine, said horizontal support means being rigid in the horizontal fore and aft direction to prevent fore and aft swaying of the engine, but being pivotally connected to the engine and to the frame, and said horizontal support means being laterally displaced from the center of gravity of said engine.
