UNITED STATES PATENT OFFICE.
GEORGE M. BARI), OF CHICAGO, ILLINOIS.
ROTARY ENGINE.
To all whom it may concern:
Be it known that I, GEORGE M. BARD, a citizen of the United States, residing at Chicago, in the county of Oook and State of Illinois, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification.
The object of my invention is to produce a simple yet efficient rotary engine wherein the rotating eccentric part may be provided with a continuous surface without openings.
The accompanying drawings illustrate my invention: Figure 1 is an axial section, Fig. 2 a transverse section on line 2 2 of Fig. 1 Fig. 3 a sectional detail of the connection between the vane and eccentric, and Fig. 4 a section on line 4 4 of Fig. 3.
In the drawings, 10 indicates a cylinder formed in any desired manner preferably by means ofvsimilar arc sections 11 provided at each end with radial wings 12 between which are clamped U-shaped portions 13, thus forming radial pockets 15 opening into the Mounted in the pockets 15 so as to reciprocate therein are vanes 16 which are supported at their edges in radial slots or grooves 17 formed in the arms of a spider 18 one of which is secured in each end of the cylinder 10 and held against rotation. J ournaled in the two spiders 18 is a shaft 19 which carries an eccentric body20 adapted to engage the cylinder 10 at one point and to be engaged by the inner ends of the vanes 16. The spiders 18 lie immediately adjacent the ends of the eccentric 20 and secured to the shaft 19 immediately outside of each spider 18 is a plate 21 which fills the end of the cylinder and rotates with the shaft 19. Each end of the cylinder, outside of the plate 21 is closed by a suitable cap or head 22 which lies a short distance from the adjacent platev 21 so as to provide a steam space 23. Formed through one of the plates 21 are inlet ports 23 (one or more) and formed through the other plate 21 are exhaust ports 24 (one or more). The inner ends of the vanes 16 are provided with any suitable means for forming a steam-tight joint with 'the surface of the eccentric body 20. In the construction shown the vane is provided at its inner end with asocket 25 adapted to re- Speciiicaton of Letters Patent. j
Application filed March 5, 1906. Serial No. 304,157.
ceive a shoe 26 which shoe may oscillate in the socket 25 so that its inner wearing surface may at all times lie properly against the surface of the eccentric. It is desirable that some means be provided to positively reciprocate the vane 16 in both directions by the rotation of the eccentric body 20, and for this purpose each inner corner of the vane is provided with an extended lip 28 which overlaps the eccentric and carries a pin 29 upon which is pivoted a shoe 30 lying in an angular groove 31 formed in the adjacent end of the eccentric body, the arrangement being such that as the eccentric is rotated the vane will be positively reciprocated, and shoe 26 will remain in contact with the surface of the eccentric. x
In operation, with the parts in the position shown in Fig. 2 steam will enter through ports 23 and cause a rotation of the eccentric 20 in the direction indicated by the arrow. As the eccentric advances the plates 21 advance with it and when ports 23 pass the next forward vane 17 steam is admitted into the space immediately in front of said vane. In the meantime steam is exhausted through the exhaust ports24, said exhaust ports being carried around as the eccentric rotates. It will be seen, therefore, that there is a continuous admission of steam into successive portions of the cylinder and a continuous exhaust from successive portions of the cylinder in immediate advance of those portions into which steam is being admitted.
I claim as my invention:
1. In -a rotary engine comprisinga cylinder, an eccentric body rotatably mounted therein, a vane projected into said cylinder and coacting with the eccentric body, a pair of port plates mounted in the cylinder and rotating with the eccentric body, and having inlet and exhaust ports respectively communicating continuously with the interior of the cylinder.
2. In a rotary engine, the combination, with a cylinder, an eccentric body rotatably mounted therein, and a vane projected into said cylinder and coacting with said eccentric body, of a stationary spider mounted in each end of said cylinder and provided with Patented June 2, 1908.
