UNITED STATES JOSEPH B. BENNETT, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN ROTARY ENGINES.
Specication forming part of Letters Patent No. 123,144, dated January 30, 1872.
Specification describing certain Improvements in Rotary Engines, invented by JOSEPH B. BENNETT, of the city of Brooklyn, county of Kings and State of New York.
The nature of my invention consists in several improvements in the construction of my rotary engines, whereby their durability and eii'ectiveness are increased.
Figure l represents a face view of the engine With the head and cover removed; Fig. 2, a section of the same Without the pistons; Fig. 3. a section ot' head or cover; Fig. 4, piston in perspective.
A, outer cylinder; B B, inner cylinder, pro-- vided with slots for the reception ot' the pistons (l G C U, and recessed at each end for the rings D D. The wheel or cylinder B B is eccentric to the. cylinder A, so that (with or without packing) it forms a tight joint at the point of contact with inner rim of cylinder A, as shown. It will be seen that the distance between the outer ends of pistons 2 2 is less than that between the outer ends of 3 3. To compensate for this difference and for the Wear on the pistons the rings D D are provided with the springs E E or their equivalents for the purpose. The rings may be made with iiat surfaces, and the springs be applied to the pistons, or the springs may be applied in any other suitable manner. It is found that the rings receive an independent oscillating rotary motion, Which, though slight, is sufficient to Wear the ends or edges of the pistons at the point of contact. To diminish this wear I have provided the inner edges of the pistons with steel bearings or shoes I I and 4; either form or any other form may be used which will accomplish the purpose. Three or more pistons may be used. H in Fig. 3 represents a ringpacking, arranged so that when in position its periphery is opposite that of the cylinder B B. This packing is operated by steam or suitable springs, not shown. The bearings for the shaft are increased by extending the hub G into the engine-casing.
l do not claim an engine made with three pistons and similar rings when the springs are set in grooves in said rings.
What I claim, and desire to secure by Letters Patent of the United States, is
l. The combination of the loose rings D D With four or more pistons, C O, in a rotary engine, the inner cylinder B B of which is eccentric to the outer cylinder A, substantially as shown.
2. The springs E E, in combination with the rings D D and four or more pistons in an yengine, the outer cylinder A and inner cylinder B of which are eccentric to each other, substantially as specified. Y
3. The combinat'on of the loose rings D with pistons C C having shoes I or 4, all substantially as and for the purpose set forth.
