HARLEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Engines, of which the following is a specification. One of the objects of this invention is to insure uniform correlated expansion of the co-operating members of the mechanism. A further object is to insure regular operation of the engine irrespective of the temperature at which the engine is operating. It further object is to provide a motor in which the errors of timing of the mechanism due to expansion of the parts are eliminated. A further object is to provide a light weight motor."
The patent act of 1790 established the rules for submitting a patent application. Each application had to be submitted with specifications, a patent drawing, and if possible a model of the invention. Eventually, models were no longer required.
