LINWOOD A. HORD, OF ADAMSTON, WEST VIRGINIA.
ROTARY ENGINE.
Application filed. January 29, 1907, Serial No. 354:,669. Renewed May 2, 1908.
To all whom it "may concern:
Be it known that 1, LINWOOD A. Horn), a citizen of the United States, residing at Adamston, in the county of Harrison, State of Nest Virginia, have invented certain new and useful Improvements in Rotary Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to rotary engines and more particularly to that class in which the cylinder of the engine forms the rotary member, the shaft being non-rotatable.
In carrying out my invention I employ a cylinder having heads which rotate therewith and a piston which is located within the cylinder and around which the cylinder rtates. This piston is of ordinary construc tion, including slidable blades or heads against which the steam impinges and upon the piston and concentrically thereof are formed collars, there being one collar on each side of the piston and connected with these collars or formed integral therewith is the en gine. Upon each of the cylinder heads there is formed a pair of concentric flanges the inner one of which embraces the corresponding collar and engaged over the outer flanges of each pair is a steam chest in communication with which is a steam inlet pipe. A steam port is formed in each cylinder head and has communication with the respective steam chest and also at times, with the cylinder itself.
In the accompanying drawings, Figure 1 is an edge view of an engine constructed in accordance with my invention, Fig. 2 is a side elevation thereof with one of the cylinder heads removed, Fig. 3 is a detail vertical longitudinal sectional view, taken centrally therethrough and showing the inlet port of the engine closed.
Referring more specifically to the drawings the engine is shown as comprising a cylinder 5 having heads 6. The cylinder is hollow but has a portion of its inner periphery eccentric to the remaining portion thereof as in dicated by the numeral 7 and arranged within the cylinder is a piston 8 which is circular in form and is provided with slidable blades or heads 9 which contact at their ends with the inner periphery of the cylinder and are moved by the eccentric portions 7 thereof when one of their ends is in engagement with 1 the engine.
Specification of Letters Patent.
Patented Nov. 3, 1908.
Serial No. 4=30,538.
the said portion, to bring their opposite end into engagement with the remaining portion. Each of the cylinder heads is provided with an opening 10 through which projects a collar 11 which is formed integral with the corresponding side of the piston 8. The engine shaft is preferably formed in sections 12 which are connected or formed integral with the collars 11.
Formed integral with each cylinder head 6 is a pair of concentric flanges, the inner one being indicated by the numeral 13 and the outer one by the numeral 141 and the inner flange extends around the opening 10 in its respective cylinder head and surrounds or embraces the collar 11. The collars of each pair are suitably braced as at 15 and formed in each cylinder head is a radially extending port 16 which has communication at its inner end with the interspace between the flanges 13 and 1 1 and at its outer end, at all times with the inter-space between the main portion of the inner periphery of the cylinder and the opposing portion. of the periphery of the piston.
The outer flange 14 is provided with a plurality of grooves 17 and fitted over each of these flanges 1 1 is a cylindrical steam chest 18 which is provided upon its inner periphery with a plurality of spaced ribs 19 which seat in the grooves 1 7. To permit suchfltting of the steam chest over the flange, each of the steam chests is slit at diametrically opposite points and is provided upon opposite sides of each slit with ears 20 which are apertured for the passage of bolts 21 upon which are engaged nuts 22, it being understood that these bolts or nuts serve as a means for tightening the engagement of the chest upon the flanges. Each of the steam chests 18 is reduced at a point slightly outwardly of or beyond the end of the collar 11 as at 23 to iit around the shaft 12, there being ribs 24: formed upon the shaft and projecting into grooves 25 in the reduced portions of each steam chest. This means of connecting the steam chests with the flanges 14 and with the shaft serves to form an effective packing to prevent escape of steam and also serves to hold the parts in their proper relation. Communicating with each of these steam chests 18 is a steam inlet pipe 26 and 'these pipes are connected with a steam main 27 and are each provided with a cut-ofl valve 28 whereby steam may be admitted to either side of the piston to reverse A steam exhaust pipe 29 also leads from each steam chest and is provided I with a suitable cut-off valve and it will be l readily understood that when steam is being admitted to the engine at one side, the exhaust pipe from the steam chest at the opposite side is open, the exhaust at the first mentioned side'being of course closed.
From the foregoing description and from I the drawings it will be observed that the cylinder itself is the only member which re volves and it is hence used as the fly wheel of the engine.
What is claimed is,
1. An engine of the class described comprising a rotary cylinder, a piston arranged within the cylinder, said piston being stationary, concentric flanges formed upon the heads of the cylinder, said heads having inlet ports formed therein and communicating with the interspace between the flanges and with the cylinder, shafts connected with the opposite sides of the piston, steam chests I engaged over the outer one of the concentric flanges upon the cylinder heads and connected with the shafts, an inlet communicating with each steam chest and an exhaust leading therefrom 2. An engine of the class described comprising a rotary cylinder, a piston arranged within the cylinder, said piston being stationary and including heads, concentric flanges formed upon each of the heads, collars carried by the piston at opposite sides thereof and embraced by the corresponding inner flanges of each pair, said heads having inlet ports formed therein and communicating with the interspace between the pairs of flanges and with the cylinder, said inlet ports being extended in different directions, nonrotatable steam chests secured over each of the outer flanges of the pair, each of the outer flanges being provided in its outer periphery with a plurality of grooves, ribs formed upon the outer periphery of each steam chest provided within the grooves in the flanges, an inlet communicating with each steam chest and an exhaust leading from each steam chest.
In testimony whereof, I affix my signature, in presence of two witnesses.
LINWOOD A. HORD.
