IMPROVEMENT IN ROTARY ENGINES. 1
Specification forming part of Letters Patent No. 168, l 14, dated September 28, 1875; application filed March 17, 1875.
had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
The nature of my invention consists in the construction and arrangement of a rotary engine, as will be hereinafter more fully set forth. In order to enable others skilled in the art to which my invention nppertains to make and use the same, I will now proceed to de-' scribe its construction and operation, referring to the annexed drawings, in which-' Figure 1 is a plan view of my rotary engine. Fig. 2 is a longitudinal section of the same through the line a: m, Fig. 1. Fig. 3 is a side view of the engine with the outside plate removed. Fig. 4 is a section through the line y 3 Fig. l. 1
A represents the outside casing or shell of my engine, made in the form of three cylindrical chambers connected, as shown, by running into each other. Through the center of the middle cylindrical chamber passes a shaft, B, and through the center of each of the side chambers passes a shaft, B, all of said shafts passing through suitable stuffing-boxes attached to the heads or end plates of the casing. On the center shaft B issecured a wheel or cylinder, 0, provided onits periphery with four semicircular lugs or projections, to a, at equal distances apart, and on each of the shafts B is secured a wheel or cylinder, 0, provided in its circumferencewith four semicircular recesses, b, at equal distances apart, and of such size as to, have the lugs or projections a fit therein when the wheels revolve. d d are steam-spaces between outsidecylinders O G and the case A. e e are bearings, making steam-joints between the case and cylinders. h h are steam-entrances, and i i are the exhaust-ports. At one side of the casing A is an interior packing-plate, D, pressed against the ends of the cylinders O O on that side by means of springs E E, and the tension of these springs is regulated by means of set-screws m m. The shafts B B1 are connected together by means of cog-wheels G G, for rotating the cylinders together. The steam enters through the ports h h, and, coming in contact with the lugs or projections to a, drivesthe wheels around, the steam escaping through the portsi The steam is taken in on the two opposite sides of the center wheel 0, so as to avoid side pressure. The two outside wheels 0 are abutments for the steam to back against, the spaces d allowing the steam to pass as far back as possible without escaping, for the purpose of taking' off allside pressure on the outside cylinders, excepting enough to hold them snug in against their bearings e, and also against the face of the center bearings.
I do not broadly claim a cylinder of" a rotary engine constructed to form a steamspace around a portion of the periphery of the revolvin g abutment, whereby the latter is nearly balanced by the pressure of steam, as such is not my invention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is-
The combination of the case or shell A, the wheels or cylinders O and O O, with their respective lugs a and recesses 12, steam-spaces d, bearings e, inlets h h, and outlets it, all constructed substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 6th day of February, 1875.
