Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
73 words
An internal combustion engine and bearing arrangement for an engine driven accessory, said engine having a driven shaft journalled by a pair of mating light alloy castings, a reinforcing element formed front a stronger material than said castings embedded in one of said mating castings, said driven shaft being supported at least in part by the reinforcing element, and a component of said engine driven accessory being supported directly by said reinforcing element.
Claim 2
Dependent Claim
73 words
An internal combustion engine and bearing arrangement for an engine driven accessory, said engine having a driven shaft journalled by a pair of mating light alloy castings, a reinforcing element formed front a stronger material than said castings embedded in one of said mating castings, said driven shaft being supported at least in part by the reinforcing element, and a component of said engine driven accessory being supported directly by said reinforcing element.
Claim 3
Dependent Claim
38 words
An internal combustion engine and bearing arrangement as set forth in claim 1 wherein the pair of mating castings comprise a cylinder block and a bulkhead member cooperating to journal the engine driven shaft that comprises a crankshaft.
Claim 4
Dependent Claim
27 words
An Internal combustion engine and bearing arrangement as set forth in claim 2 wherein the engine driven accessory is driven from the crankshaft by a flexible transmitter.
Claim 5
Dependent Claim
70 words
An internal combustion engine and bearing arrangement for an engine driven accessory, said engine having a crankshaft journalled by a pair of mating light alloy castings, said engine driven accessory being driven from said crankshaft by a flexible transmitter, a reinforcing element formed from a stronger material than said castings embedded in one of said mating castings, and a tensioner for said flexible transmitter supported directly by said reinforcing element.
Claim 6
Dependent Claim
70 words
An internal combustion engine and bearing arrangement for an engine driven accessory, said engine having a crankshaft journalled by a pair of mating light alloy castings, said engine driven accessory being driven from said crankshaft by a flexible transmitter, a reinforcing element formed from a stronger material than said castings embedded in one of said mating castings, and a tensioner for said flexible transmitter supported directly by said reinforcing element.
Claim 7
Dependent Claim
30 words
An internal combustion engine and bearing arrangement as set forth in claim 4 wherein the tensioner is comprised of a pivotally supported member for applying pressure to the flexible transmitter.
Claim 8
Dependent Claim
31 words
An internal combustion engine and bearing arrangement as set forth in claim 5 wherein the pivotal support for the member is provided by a pin carried directly by the reinforcing member.
Claim 9
Dependent Claim
42 words
An internal combustion engine and bearing arrangement as set forth in claim 5 wherein the pivotally supported member is biased by a torsional coil spring having an end engaged with the pivotally supported member and another end engaged with the bulkhead member.
Claim 10
Dependent Claim
41 words
An internal combustion engine and bearing arrangement as set forth in claim 7 wherein the other spring end is trapped in a slot formed in the bulkhead member and closed by the engagement of the bulkhead member with the cylinder block.
Claim 11
Dependent Claim
31 words
An internal combustion engine and bearing arrangement as set forth in claim 8 wherein the pivotal support for the member is provided by a pin carried directly by the reinforcing member.
