Abstract
Abstract An engine mount assembly for resiliently supporting an engine on a frame of a motor vehicle includes a pair of mounting brackets and an insert. The insert and one of the brackets have cooperating rails preventing relative movement therebetween in two mutually perpendicular directions while rivets normally secure the insert and this one bracket against movement in a third direction perpendicular to the other two directions. Rubber is secured between the other bracket and the insert for yieldingly resisting relative movement therebetween to normally isolate engine vibrations and these members also have abutments which engage on predetermined relative movement therebetween in the stated third direction to transmit force to the rivets. Rubber secured between the insert and the stated one bracket operates to yieldingly resist movement therebetween in the stated third direction when the rivets are sheared.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
An engine mount assembly for resiliently supporting an engine on a frame comprising a pair of mounting brackets, an insert located between said brackets, securing means for normally securing said insert and one of said brackets, first resilient means secured between the other of said brackets and said insert for normally yieldingly resisting relative movement therebetween, said other bracket and said insert having abutment means operable to engage on predetermined relative movement therebetween in one direction to mechanically transmit load between said other bracket and said insert to said securing means, and second resilient means secured between said insert and said one bracket for yieldingly resisting movement therebetween when said securing means is forced to release said insert and said one bracket for relative movement.
Claim 2
Dependent Claim
125 words
An engine mount assembly for resiliently supporting an engine on a frame comprising a pair of mounting brackets, an insert located between said brackets, securing means for normally securing said insert and one of said brackets, first resilient means secured between the other of said brackets and said insert for normally yieldingly resisting relative movement therebetween, said other bracket and said insert having abutment means operable to engage on predetermined relative movement therebetween in one direction to mechanically transmit load between said other bracket and said insert to said securing means, and second resilient means secured between said insert and said one bracket for yieldingly resisting movement therebetween when said securing means is forced to release said insert and said one bracket for relative movement.
Claim 3
Dependent Claim
143 words
An engine mount assembly for resiliently supporting an engine on a frame comprising a pair of mounting brackets, an insert located between said brackets, securing means including shearable means for normally securing said insert and one of said brackets, first resilient means secured between the other of said brackets and said insert for normally yieldingly resisting relative movement therebetween in three mutually perpendicular directions, said other bracket and said insert having abutment means operable to engage on predetermined relative movement therebetween in one of said directions to mechanically transmit load between said other bracket and said insert to said shearable securing means in excess of the load transmission ability of said first resilient means, and second resilient means secured between said insert and said one bracket for yieldingly resisting movement therebetween in said one direction when said shearable means is forced to shear.
Claim 4
Dependent Claim
143 words
An engine mount assembly for resiliently supporting an engine on a frame comprising a pair of mounting brackets, an insert located between said brackets, securing means including shearable means for normally securing said insert and one of said brackets, first resilient means secured between the other of said brackets and said insert for normally yieldingly resisting relative movement therebetween in three mutually perpendicular directions, said other bracket and said insert having abutment means operable to engage on predetermined relative movement therebetween in one of said directions to mechanically transmit load between said other bracket and said insert to said shearable securing means in excess of the load transmission ability of said first resilient means, and second resilient means secured between said insert and said one bracket for yieldingly resisting movement therebetween in said one direction when said shearable means is forced to shear.
Claim 5
Dependent Claim
185 words
An engine moUnt assembly for resiliently supporting an engine on a frame comprising a pair of mounting brackets, an insert located between said brackets, said insert and one of said brackets having cooperating rail and channel means for preventing relative movement there between in two mutually perpendicular directions and guiding relative movement there between in a third direction perpendicular to the other two directions, shearable securing means for normally securing said insert and said one bracket against relative movement in said third direction, first resilient means secured between the other of said brackets and said insert for normally yieldingly resisting relative movement there between, said other bracket and said insert having abutment means operable to engage on predetermined relative movement there between in said third direction to transmit load between said other bracket and said insert to said shearable securing means in excess of the load transmission ability of said first resilient means, and second resilient means secured between said insert and said one bracket for yieldingly resisting guided movement there between in said third direction when said shearable securing means is forced to shear.
Claim 6
