ROTARY STEAM-ENGINE.
SPECIFICATION forming part of Letters Patent No. 517,790, dated April 3, 1894.
Application filed ruiy 18,1893. y
To a/ZZ whom it may concern.- e
Be it known that I, WALTER MOsELY BYRD, a citizen ofthe United States, residing at Mount Gilead, in the county of Montgomery andState of North Carolina, have invented a new andA useful Rotary Steam-Engine, of which the following is a specification.
This invention relates to rotary steam engines, and it has'for its object to provide certo tain improvements in rotary engines to secure order to more effectively secure the objects zo sought for.' v
With these and other objects in view, which will readily appear as the nature of the -invention isbetter` understood, the same consists in the novel construction, combination,
fand arrangement of parts hereinafter more fully described, illustrated, and claimed.
In the accompanying drawings:-Figure-1 is a central vertical longitudinal sectional View of a rotary steam engine constructed iny 3o accordance with the present invention.
Fig. 2 is a vertical section 'on the line of packing abutment one of the side plates of which is shown partly in'section. l
Referring to the accompanying draWings,-A represents a suitable bed or base to which is secured the sectional steam cylinder B. The sectional steam cylinder B, incloses therein a circular steam chamber, as is usual in engines 4o of the rotary type, and said steam cylinder is pierced at one side by the steam inlet port C, and at an opposite side by the 'exhaust port D. Intermediate of the inlet and exhaust ports of the steam cylinder the same is provided in its inner wall with an olstanding segmental recess E, which is adapted to receive the segmental packing abutment F. `The segmental packing abutment F, extends almost entirely aroundthe'interior wall of the steam cylinder, and is so disposed between the inlet and exhaust ports as to have its ends Fig. 3 is a detail in perspective of thel sain No. 480.835. (No more project inwardly within the steam cylinder beyond its inner wall, whereby the exhaust space G, is left `between its projecting ends, and which exhaust space always communicates with the exhaust port D,to insure'a free exhaust of the utilized steam from the cylinder. .f
`The 'said packing abutment F, is provided Vnear one end thereof withthe inlet opening H,
which is in a line with the inlet port C, of the cylinder, and communicates directly with the first one`ofa series of off-standing impacting pockets or recesses I, formed in the body of the impacting abutment and standing off from the interior steam space or chamber of the cylinder. The said impacting pockets or recesses may be arranged or formed in the packing abutment in any number found expedient to employ, and each of said pockets or recesses Vis provided with a rear straight shoulder wall J, and aforward curved Wall K. The several impacting pockets or recesses I, communicate directly with each other by the intermediate connecting channels L, which channels are walled in atl one side, as Well as the pockets or recesses themselves, by the removable abut- 2 ment ring or plate M. 'The abutment ring or lplate M, is formed of any suitable packing material and has its ends register Withthe shoulders m, formed near the end of the packing abutment for the reception thereof, and the said removable abutment plate, which is more properlya cap plate for the abutment, is held in proper position facing the inner side of the packing abutment, by the inner projecting ends of the abutment side plates N, which plates are bolted to the opposite sides of the abutment so as to inclose the impacting pockets or recesses and to hold the removable cap plate M, in proper position.
The removable curved cap plate M, vis bored with a series ofsteam openings or ports O, which steam openings or portsv are in a direct line with the forward curved walls K, of each of the impacting pockets or recesses, whereby means are provided for directing the impact of steamfrom the pockets squarely against the shoulders of the steainbuckets P, formed in the periphery of the steam drum Q. The
steam drum Q, is mounted on the shaft R,'
ICQ
inder in contact with the removable abutment plate M, and out of contact with the remaining inner portion of the cylinder, where the exhaust space G, is located, so that as each bucket of the steam drum leaves one end ot' the packing abutment it discharges directly into the exhaust space of the cylinder.
. N ow from the foregoing it willbe apparent that the series of inclosed and intercommunieating impacting pockets or recesses form a steam impacting chamber or reservoir into which the steam is impacted until it becomes as dense as the steam in the boiler, and consequenily having the same pressure as said steam, so that it will be practieably effective when it is expanded squarely' against the shoulders of the drum buckets through the steam openings or ports leading from the sev- -eral impacting pockets or recesses of the impacting chamber formed thereby. By reason of separating the impacting recesses or pockets from the periphery or face of the steam drum by means of the removable abutment cap plate M, the steam drum is relieved of all unnecessary pressure, while at the same time the advantage of a double impact is secured, first from the boiler to the steam impacting chamber, and then from the several impacting pocketsor recesses of such chamber to the steam drum, and it is to be observed that owing to the proximity of the steam impacting chamber to the steam drum and the area thereof, an over supply of closely impacted steam is always contained within the steam cylinder ready to spend its expansive force against the shoulders of the steam buckets.
Changes in the form, proportion and fthe minor details of construction may be resorted to without departing from Vthe principle or sacrificing any of the advantages of this invention'.
Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-
l. In a rotary steam engine, the steam cylinder having a series of interior impacting pockets communicating with each other and the steam inlet, a cap plate facing the inner Wall of the steam cylinder' to inclose said impacting pockets and having steam openings or ports aligning with the forward Walls of each pocket, and the bucket drum substantially as set forth.
2. In a rotary steam engine, the cylinder having oppositely located inlet and exhaust ports, a segmental packing abutment seated within the cylinder between the ports thereof and havingaseries of impacting pockets communicating with each other and the inlet port, a removable abutment cap plate facing the inner side ot' said packing abutment and having a series of steam openings or ports communicating with said impacting pockets, and a rotary bucket drum or piston mounted within said cylinder and traveling in contact with said abutment cap plate, substantially as set forth. L
3. In a rotary steam engine, the combination of a steam cylinder having oppositely located inlet and exhaust ports, a segmental packing abutment mounted inside or" the cylinder between the ports thereotl and provided with a series of intercommunicating impacting pockets or recesses also communicating with the inlet port, said impacting pockets each having a rearstraight shoulder wall and a forward curved wall, a removable cap plate fitted to the inner side ol said packing abutment and provided with a series of steam openings or ports disposed in a direct line with the forward curved wallotI each impacting pocket and a bucket steam drum mounted within said cylinder and traveling in contact with said removable cap plate, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto aitxed my signature in the presence of two witnesses.
