PATENT OFFICE.
IMPROVEMENT m STATIONARY enemas.
Specification forming part of Letters Patent No. 133,926, dated December 17, 1872.
To all whom it may concern:
Be it known that I, CHARLES S. CRANE, of
' the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stationary Engines, of which the following is a full, clear, and exact I descriptiomreference being had to the accomrpanylng drawing making a part of this specification, in which Figure l is an elevation, having part of the casing removed, showing the interior of the steam-chest and a vertical section of one cylinder-with its valves and passages; showing also a portion of the wall C cut away and valve F removed; Fig. 2 shows a plan of one 7 r end-the other end of the figure is a horizontal section -on line w, except that the valve is shown in section on line y; Fig. 3, a plan view and Fig. 4, a vertical transverse section of one valve; and Fig. 5, a plan of the other .valve.
My invention is designed to be used with a double-cylinder engine; and consists in making the cylinders and steam-chest together, and in the combinations hereinafter claimed.
In the'drawing, AA represent two vertical cylinders; B, steam-chest, located between the cylinders; C, a partition wall; D, one of the outer walls of the steam-chest; E, valve, opening and closing the ports to the cylinder A. This is, in fact, a double D-valve, the
A part 9 corresponding with the ordinary D- valve, and the part h being an outer casing,
leaving an open space, 6, between 9 and h. a b, ports or openings in the wall C, the former communicating by means of the passage 01, which is between the walls C D, with the space 0. between the two parts g h of the valve E; the latter,b, communicates by means of a passage, 5, similar to d, between the walls C D, with the under side of the valve E; and this last-mentioned passage is indicated by means of. dotted lines in Fig. 1. c is the exhaust-outlet. The ordinary D-valve F (see Figs. 3 and 4) is used with the port'sand openings 0. b c. k and m are induction-ports to the cylinder A. vided with induction-ports similar to k m,
. which are opened and closed by a valve similar to E, and there are passages from a b to the left similar to those already described. I cast the cylinders and steam-chest together.
The cylinder A is pro- Operation.
. Steam is admitted to the steam-chest in the usual manner. Suppose the port b and exhaust-opening e to be covered by the valve F, steam will pass from the chest through the port a and passage d to the space 6 between the parts 9 h of the valve E. If, now, the valve E be lifted so as to open the passages k m steam will pass from E through h to the lower end of the cylinder, and as the piston rises the exhaust steam will pass out through at beneath g' to and through the passage t to the port b, thence under the valve F to the opening 0. It, then, the valve F be moved so as to open the port b and cover the port a and opening 0. the operation will be reversed-steam will pass through the port b and passagei and come beneath the part g of the valve E; and this valve being raised so as to open the ports m and h the steam will pass through m to the upper end of the cylinder,,and as the piston descends the exhaust steam will be forced out through 70 into the space c between g and h, and thence through passage 01 to the port a and beneath the valve E to the outlet '0. At the same time steam will pass to and from the cylinder A, substantially as before described.
Among the advantages of this construction the ifollowing maybe named: The valves being in one chest willall be exposed to view whenever the chest is opened, so that if anything should get out of order the defective part can be more readily discovered than'if there were three separate steam-chests. The valve E will also be heldin place by the pressure of the steam in the chest instead of by a spring, which has been used when this valve has been in a separate chest.
What I claim as new is as follows:
The combination of the cylinders A and A and steam-chest B, made in one piece with the valves E, g, and F, ports a b, passages d and 1., and exhaust c, all constructed and operatln g substantially as specified.
CHARLES S. CRANE.
