Two pistons or wings, C D, extend diametrically from The shaft of the engine extends a short distance into the cylinder d, to the inner periphery of the case A. a cylindrical pump-case, H, fixed to the engine-cylinder There are also tw'o passages, f and g, leading through bya neck, I, and arranged with respect to it in manthe pistons, the cylinder d, and the shaft B. These ner as represented. On the part of the shaft B, which passages go parallel to one another through the shaft enters the interior space` g' of the pump-case, 1s a B and the cylinder al. Thence, each goes through the ring, I', which is fixed to and so as to be y revolved by two pistons in opposite directions, in manner as shown the shaft. This ring, and the end of the' shaft B, abut in fig. 4, the same being so as to open communication directly against a cylinder, K, which is fastened to the between the space over each piston with that below outer head h of the pump-case. the other piston.

There are also -two passages, if c2, leading through the block l. Each of such passages opens communication between the spaee below one piston and that above the other of the pump-chambers l m. By the employment of the stationary cylinderK, arranged with the partitions 1"-(1, the passages of communication, the shaft B, and the pistons i" L", and their connecting annulus I, l am enabled to make the passages b'` c2 much larger than I could were I toinake them through the shaft B. '.lhe'same may be said with respect to my arrangement of the passages 7" q of the steam-engine, as, by arranging them in the pistons OD, and through the shaft B and cylinder (l thereof, they may be made much larger than they could be were they to be run through the part (l and the shaft B, for in such case they would have to be very narrow, on account of the pistons, when at work, approaching so closely to the partitions t b.
\Vhen steam is let into the passage of the steamchest of the engine, and the shaft B is turned so as to cause one of the pistons C to rise and throw oiiits valve b, steam will pass through the seat of such valve into the steam-chest Y, and, by acting' against the piston Gr, will move it endwise within the chamber I, so as to enable steam to pass through the passage f', and into the passages s, y, l11,', and 11:, of the piston-Valve G. In this case the annularl passage a" will beidirectly over the port o leading to the raised piston. The passage yuf will Aopen communicationbetween the port p and the eduction-passage on. The steam will rush, through the passage o, into the spaee over the piston c, and will also pass, through the passage j, into the space below the piston D. The steam, acting against the pistons, Will move them in opposite directions, until the piston D may be thrown up against the valve-stem c1, so as to raise the valve b thereof. As soon as this may take place,'the steam will enter the chamber l and drive the piston-valve. in the direction opposite lto which it was previously moved, so as to cause the steam to produce a reverse movement of the pistons. The exhaust steam of the chamber lwill i'low through the valve-stem passage a" leading from the spaee I, into the space over the piston C. Such passage a* should have a diameter a little greater than that of the valve-stem. The same may be said with respect to the passage b" of the other valve-stem. Each passage, however, should be of such diameter as to discharge the exhaust steam'so slowly as to cause the 1 iston-valve to be cushion'ed7 by the' steam, while the valve may be in movement, the cushioning of the valve being to prevent its momentum from breaking its stop or stud, fc, or otl'ierwise doing damage.
` The pistons will be moved` with oscillatory movements, so as to impart to the shaft B a reciprocating rotative motion, and cause it to work the two pistons of the pump, which is a double-acting lifting and forcepump.
iVhat 1 claim as my invention in the above-described punniiing-engine, is as follows, viz
The combination of the stationary cylinder K, and its passages b2 ci, with the pump-pistons 17h' connected with the shaft B, and arranged in the pump-case, provided with valves, and partitions, and induction and eduction-conduits, as explained.
Also, the arrangement of the steam-engine and the pump, and their connection by the neck 1, and the shaft B, as described.
