SHARP
v.
RIESSNER.



APPEAL FROM THE CIRCUIT COURT OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK.

Author: Blatchford

[ 119 U.S. Page 631]

 MR. JUSTICE BLATCHFORD delivered the opinion of the court.

This is a suit in equity brought for the alleged infringement of letters-patent No. 177,334, granted to Abner B. Hutchins, May 16th, 1876, for an improvement in hydro-carbon stoves. The specification and drawings are as follows:

Vertical tubes or flues are placed in the hot-air cylinder in such positions as to act as chimneys for the burners. Mica windows are placed in the sides of these flues or chimneys in such positions as to enable the operator to observe the flame of the burner and to regulate the same as circumstances may require.

Fig. 2 is partly a plan and partly a section of the same. In this view the half of the top-plate only is removed, so as to disclose the construction of the hot-air cylinder and the flues or chimneys. Fig. 3 is a sectional plan of the stove, taken just below the top-plate of the water-chamber, and showing a part of the top-plate of the oil-vessel or reservoir broken out.

"He base of the stove consists of a vessel, A, resting, for

     convenience, on short legs a. This vessel is intended to contain water, and has a top plate, A', which is preferably made of cast metal, and strong enough to support all the parts of the stove which are above it. This plate A' is annular in form if the stove is of general cylindrical ...
