Abstract
Abstract The specification describes the making of a gudgeon pin connection in the construction of internal combustion engine, the connection being characterized by the facing of the ends of the pin, which forms the connection between the small end of a connecting rod and piston of the engine, with material different of that of the pin itself deposited in layers of appropriate thickness.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
In an internal combustion engine having a piston and a connecting rod connected to said piston, a gudgeon pin connection between the small end of the said connecting rod and the piston comprising a gudgeon pin of the maximum permissible length and fixed on each end for contact with the wall of the cylinder, the ends of the pin being faced with material, different from that of the pin itself, deposited over and metallically bonded to the end faces in layers of approximate thickness to act as bearing surfaces.
Claim 2
Dependent Claim
89 words
In an internal combustion engine having a piston and a connecting rod connected to said piston, a gudgeon pin connection between the small end of the said connecting rod and the piston comprising a gudgeon pin of the maximum permissible length and fixed on each end for contact with the wall of the cylinder, the ends of the pin being faced with material, different from that of the pin itself, deposited over and metallically bonded to the end faces in layers of approximate thickness to act as bearing surfaces.
Claim 3
Dependent Claim
21 words
In an internal combustion engine according to claim 1, in which the ends of the pin are faced with aluminum bronze.
Claim 4
Dependent Claim
38 words
In an internal combustion engine according to claim 1, in which the end faces of the said pin are machined to a radius a little less than that of the piston about axes normal to the pin axis.
