Application filed-I September 12, 1921; 'S eriaLsNo. 499,885.
Be; it known that I, JAMES B. BUaKs, a citizen oftheUnited States,- residing' at Houston, in the-county of Harris and State of Texas, have invented certain new and use- .ful Improvements in anEngine, of which the following, is a specification.
This invention relates to new and useful improvements in an engine,
One object of theinvention is to provide,
an engineof the character described, spe cially adapted. foruse on boats and other water craft, and which is struction, is made offewparts and is easily controlled. d i
Another objectis to provide an engine of the character described adaptedfor the use of steam asa motive power an-d equipped with a novel formv of valve fortheapplication thereof. H
With the above and other objects in view, this invention has particular relation to certain novel features ofconstruction; operation and arrangement of parts an example this specification I and of. which isv given in illustrated in the accompanying drawings,

View of this form oftheengine. I f 7 Referring more particularly te -the drawing, the numeral 1 designates the base on which, the-cylinder block2 is mounted. This block, as shown, has, three cylinders, 3,; 4, .5. In these cylinders; the pistons -6 ork, f ea risen tas e an s ed a: th s ants aft 8 v y at he u ua sen- 7 "ing 11 mounted onthe base 1.
of: simple coni i will, have-registered with the" necting rods'i. The crank shaft is rotatably mountedin suitable bearings in'the engine base 1 and; one end thereof is formed to beconnected to the work to be driven. The
other endof this shaft is connected to a. ro-
The valve 9 has the form of a hollow cylinderwith both ends closed. At opposite ends it has the annular peripheral grooves 15 and 16, the former of which communicates with the interior of the valve through the ports 17 An inlet-steam line 19 is connected into the valvecasing-ll, opposite thegroove l5, and
andthe latter of which connects with a spiralled groove 18, in the valve 9.
and 22' arranged tOIfGglStBI with said inlet 7 p and exhaust lines.
The sleeve 10 also has the outwardlyltaperingforward ports 23,24 and25, and reverse ports26, 27 and 28, arranged. in staggered;
relatiomas shown in Figure 4. 4
tates. 111g respective cylinders 3,4 and 5, as shown in .Fi 'ure 1. i Y l I gteamlenters the valve .9, from'the steam line .19, through the ports 21 and 17 and whenthe valve :port .31 registers with the pipe 34lthe steam will pass into-the expansion chamber of the-cylinderlfi.
-As the valve continues to rotate the port 31 will pass out of registration, with saidsteampipe and the exhaust groove 18 will come into registrationtherewith and the spent steam will return;through the pipe 34, the-grooves 18, and 1.6 and will be exhausted through the eX-,
spent steam will be exhausted from said last mentioned cylinder. And soon, the steam will be delivered to and exhausted from said cylinders, in succession through the pipes 32, 33 and 34, each pipe alternately delivering steam to and exhausting it from itscorresponding cylinder.
It is to be observed that the valve sleeve controls the passage of steam through the valve to the steam pipes 32, 33 and 34. This sleeve may be adjusted so. that the forward ports 23, 2d and will be in position to register with the corresponding valve ports 29. and 31 and the engine will be driven To reverse; the engine the valve sleeve may be adjusted, through the lever 13, so thatthe reverse ports 26, 27 and 28 will register with the corresponding valve ports I and the engine will be reversed. The valve sleeve ports are correspondingly tapered, as above explained, so that the path of travel of the valve ports across them may be lengthened, or shortened,-and the amount'of steam delivered to the cylinders thus controlled by a suitable shifting of the valve sleeve.
' In'the form shown in Figures 6 to 11 inelusive, provision is made for delivering steam to, and exhausting it from, opposite sides of thepistons 6. In this form the v steam pipes 35, 36 and 37 lead from one side of the casing 11 and communicate with the respective cylinders 3, 4 and 5 between the pistons 6 and the cylinder heads, and the steam pipes 38, 39 and 40 lead from the opposite sides of the casing 11 and communicate with said respective cylinders 3, 4 and 5 on the other sides'of the pistons 6. The valve sleeve, in this form, has two series of forward ports, '23 24: and 25, as well as two series of reverse ports, 26 27 and 28', oppositely arranged so as to register alternately with the respective steam pipes of the two series, 37, 36, and 35, and 38, 89, and 4:0, ofpipes. In the other respects this form of the engine is similar to that shown in Figures 1 to 5, inclusive, and hereina-bove described.
What I claim is 1.- In an englne a communication with an inlet steam'lineand also provided with an outletportand a spiralled exhaust passageway, a valve sleevearound said valve provided with an outlet port, said sleeve port alternately registerf ing witlrsaid valve outlet port and exhaust passageway. a
