the present state of the art. Still since the novelty of the improvement
claimed in No. 451, is admitted and is proven by the testimony of Henry
B. Renwick to have some utility as one of this series of patents, I
think it has sufficient utility to justify an extension.

[Sidenote: Mr. Hussey Did Not Abandon His Invention]

The contestant's counsel have argued from the testimony of Lovegrove,
that Hussey abandoned his inventions to the public by having them on
sale more than two years before applying for a patent. The testimony
does not sustain this point. Besides, an inventor does not abandon his
invention to the public by constructing a machine embracing it, in the
same factory where he makes and sells other machines. Nor by using it
experimentally in such a factory or elsewheres. Nor by keeping it in
such a factory from the autumn of one year to the harvest of the next
year. Nor by doing all or any of these things more than two years before
his application for a patent.

The statement of receipts and expenditures is unusually full and in
detail, more so than is necessary to fulfill the requirements of the
law.

There are two classes of expenditures and two corresponding classes of
receipts, _viz._:

1st. Expenditures and receipts on account of the manufacture and sale of
Reapers and Mowing Machines embracing the patentee's improvements.

2nd. Expenditures and receipts on account of the sales of Patent rights
and licenses, and compromise of infringements.

The Patentee manufactured and sold about 2,000 machines, and a few
other articles at a cost of materials and labor $195,292.88
Shop and Tools 12,500.00
One-quarter of patentee's time and expenses 9,008.22
___________
$216,801.10

The receipts on account of the sale of these manufactures were:

Cash for Reapers $216,607.90
Cash for parts of Reapers 22,416.58
Notes and Book Accounts 11,388.23
Cash for Corn Crushers 1,135.25
