TO ALL WHOM IT MAY CON CERN:
Be it known that I, FRIEDRICH FISCHER, of Garibaldi, in the county of Keokulc, and State of iowa, have invented a new and improved Rotary Engine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification, in which n Figure 1 represents a vertical section of this invention, taken in the plane indicated by the line c; zr, ng. 2.
Figure 2 is a similar section of the same, the plano of section being indicated by the line y y, fig. 1.
Figure 3 is a horizontal section of the same, 4the line .c e, hg. l, indicating the plane of section.
Similar letters of reference indicate like parts.
Thisinvention relates to a rotary engine, which is composed of an annular cylinder fitted with a piston which is secured to a piston-Wheel. The steam is admitted at' one side ol' an abutment in the cylinder, and through cavities or channels in said abutment, made or two parts, which close up by the action of springs, and which are forced apart by a Wedge-shaped projection or toe, secured to the piston, and travelling with the same in such a manner that, immediately as the pistou has passed the abutment, the two halves thcreoi` close up, and the steam acts on the piston until the wedge-shaped toe comes in contact with the abutment and forces the two halves thereof back, steam icing shui. oit at the same time until the piston has passed.
A represents the cylinder of my rotary engine, which is provided with an annular steam space, a. Into this steam space is fitted a piston, B, which is secured to the pston-nl1cel C, being connected thereto by a narrow tongue, b, which extends thr'ough a circular slit, c, in the cylinder A. This cylinder is composed of two halves, which are united by suitable screws passing through their enges, and, when the two halves are united, the slit cis formed between their-inner edges. Said slit extends from the steam space a to circular grooves, d, which are turned in the inner surfaces ot the two halves of the cylinder, and which are intended to receive the edges of the piston-wheel, ns shown in iig. 1 ot the drawing. These edges are ground into the grooves d so as to form steam-tight joints, and obviate the necessity of packed `joints or stuiling-boxcs. The piston-Wheel is mounted on the shaft D, which passes irecly through central openings in the cylinder, and has its bearings in suitable standards, E, which rise from 'the bed of the engine. Steam is admitted to the cylinder A through a pipe, F, which connects by branch pipes, e, with steam chests, G, situated on opposite sides'of thc cylinder, as shown particularly in tig. 3. Each of those steam chests forms the guide for a tlat slide, H H, and .these slides are subjected to the action of springs, whereby they are forced in until-their inner ends meet in such a manner that by said slides an abutment is formed, which is situated between steam-supply channelsgg, and the exhaust ports z. The steam-supply channels are dug out of the slides H H, and they do not extend clear through to the inner ends of said slides, as shown in gs. l and 3, so that when said slides are forced back the channels will be closed.. In order to open the slides at the proper interval,.the piston is provided with a Wedge-shaped toe, z', as shown in fig. 2, and as said piston approaches the slides, the point ot' the toe forces itself in between them, and opens them gradually for the passage of the' piston. The action of the toe on the slides is facilitated hy a chamfered recess, j, which guides the point oi` the toe, so that the same is enabled to enter between the slides without fail. After the piston has passed the abutment, the slides close up again by the action of the sprngsf, and, to prevent the slides from closing up with a sudden blow, the piston head is provided with inclined planes, 7c, which compel the slides to come together gradually. The supply of steam from the generator to the steam pipe Fis governed by a piston-valve, I, which works up and down in a chamber, K. This chamber connects by a pipe, L, with the steam generator, and it is provided -with recesses, Z, so Athat when the valve is raised to a certain height the steam which enters through the pipe L can pass through said recesses to the pipo F, but if the valve is lowered the communication between the pipes L and F is out off. The position of the valve is regulated automatically by a cam, M, which is mounted on the shaft D of the pistonwheel,4 and which acts on the end of the stem N, which passes through astnihng-box in the bottom part of the chamber K, and connects with the pistonvalve I, a spring, m, being applied so as to keep tbv end of the stom in contact with the surface of the cam. llhis cam Vis so shaped that it allows the valve to drop just before the toe enters between thc slides, and thereby the waste of steamis prevented.` The valve-stom N is made in 'two parts, which are connected by a pivot, n, and the lower end of said stem catches in a socket, o, in the end of lthe starting-bnr O. By the sctiou of the starting-bor the hinged end of thc stem can be turned o` out of contact with the surface of the com M, and by this motion the valve I is permitted to drop, and the engine is stopped; or the hinged part of the stem can be turned beck on the tsmfwhereby thc vtlvc is opened'.
iind the engine started. This engine is very simple in its constidction, and it can be run with' great economy.
What I claim as new, und desire to secure by Letters Potent, is-
1. The abutment I'I II, which opens from thc middle, in combination with the toc t' on tho advancing endr of' the piston B, constructed und operating substantially ns and for the purpose described.
2. The inclined planes 7c yon the piston heed, in combination with the abutment H H, opening from the middle, substantially as and for the purpose slot forth.
3. The hinged or jointed valve-stein N, com M, and starting-bnr O, in combination with the piston-vulve I, abutment II H, piston B, und cylinder A, constructed and operating substantially as andfor the purpose described.
