Specification of Letters Patent.
Patented Feb. 19, 1907.
Application filed September 9, 1905. Serial No. 277,660.
To all whom, it may concern.-
Be it known that I, Jnssn C. SIMMONS, a citizen of the United States, and a resident of the city of Shelby, in the county of Occana and State of Michigan, have invented certain new and useful Improvements in Rotary Engines; and I do hereby declare that the following is a full, clear, and exact description the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in engines, and more particularly to rotary engines.
I'lerctzfore the construction of rotary engines has been such that the resistance to rotation caused by the centrifugal tendency of certain moving parts has acted as a brake, and in many instances the efficiency has been seriously affected thereby. Furthermore, the valve construction of such engines is usually more or less complicated and. the numerous parts must be timed to the rotation of the revolving element of the engine and in consequence unnecessary power is consumed thereby.
The object of this invention is to provide a rotary engine in which the ixltatiin of the revolving element is perfsrniet'l with minimum resistance and in which the steam is taken alternately on opposite sides thereof.
It is also an object of the invention to afford a construction in which an. exceedingly simple and autnnatically-operating valve is provided, otatable with the head, and whereby the inlet and exhaust from the pressure-chamber is regulated with the least possible expenditure of power.
It is a further object of the invention to provide a cheap, simple, and extrcnielypowcrful and durable engine consisting of but few parts and those of such construction as not likely to get out of repair and in which the whole construction is of such a simple and direct-acting character as to enable the device to be operated by one without previous engineering experience.
The invention consists in the matters here inafter described, and more fully pointed out and defined in the appended claims.
In the drawings, Figure 1 is an end elevation of a device embodying my invention. Fig. 2 is a section taken on line 2 2 of Fig. 1.
I I I I I I I I I I I I I f Fig. 3 is a side elevation thereof. Fig. 4 is an end elevation with the head of the steamchest removed and exposing the re tary valve. Fig. 5 is an enlarged f 'aginentary detail taken on line 5 5 of Fig. 4. Fig. 6 is an enlarged fragmentary detail taken on line 6 6 of 1g. 2 1* 1g. 7 is a section taken on line 7 7 of Fig. 2. Fig. 8 is a section taken on hne 8 S of Fig. 2 and showing the exhaustchamber.
Fig. 9 is an enlarged perspective View of one of the reciprocating abutment-s. Fig. 10 is a vertical section thereof. Fig. 11 is a transverse section of the same. Fig. 12 is a plan view of the revolving disk or head, showing the reciprocating heads or abutment there in. Fig. 13 is an enlarged fragmentary detail of the revolving head, illustrating the roller-bearings for the reciprocating abutment. Fig. 14 is a section taken on line 14 14 of Fig. 13. Fig. 15 is a somewhat diagrammatic view illustrating the travel of the abutincnts. Fig. 16 is a development of the steam and pressure cylinders.
As shown in said drawings, A and A indi cate the cylinder-heads, which are peripherally flanged and the flanges of which are fitted together to afford a ground joint, as shown in Fig. 2, and between which is provided an arm. lar steain-chaniber arranged obliqlely with the plane of the revolving element. Extending centrally throi gh the cylinder is a shaft B, on which is seci red the elongated lu.b B of the rotating head B which, as shown, is CIIG. lar and of a diameter eq al to the diameter of the steam-chamber. Said pressi re or steam chamber is shaped, as shown in Figs. 2, 5, 7, S, and 15, to ailord a pl" rality of presspre-chamhers on opposite sides of the shaft and on opposite sides of the rotating head, or, in other words, the steamchamher as a whole extends obliqi ely aro'. nd' the shaft with respect to the plane of rotation of the revolnble head B iLlILS affording a plLrality of press'ure-chamb ers on alternate sides of the head.
As shown, abutments B, B", and B are carried by said head B and reciprocate in slots in the periphery thereof to project into alternate pressLre chambers on opposite sides of the head. As shown, each of said ab; tments is of the same with a longiti dinal rib b, which fits in a con'ipleniental groove in the head B and, as shown, rollers b b 1), and if provided centrally on each side' are provided on each side of said head adjacent the abutment-slots and two of which are at each side of the same. These afi'ord roller-bearings for the abutments and permit the same press;re-chambers.
to slide freely through said slots to project alternately into the pressure-chambers on either side of the same and, together with the ribs on said abutments and the grooves in the head, act to hold the abutments at all times firmly from any other movement. Said abutments are packed to afford steam-tight joints at all fo:.- r walls of the feedchamber. As shown in Figs. 9 to 15, inclusive, a strip of acking b is secured on each side of each abutment and is provided with a central in- "vvardly-directed web b which projects into the side of the abutment. Said packingstrips are notched at their edges, attording serrations on the abutment and which act to hold said packing b in operative position, while springs b engage in the central webs b and act to hold the packing firmly against the outer walls of the steam-chamber. Said packing-strips b at their ends are provided with semicircular seats, as shown in Fig. 9, and s1 pported thereon and resting in semicircular grooves in the end of the abntment are rounded packing-strips b and, as shown, a web bar b is seated in a longitrdinal groove l provided at each end of said hub,
in each end of each ab'etment and bearsagainst the inner side of the packing-strips b and is held firmly in contact thereagainst by means of springs b, tllLS affording a rolling bearing for said strips at the ends of each abutment where it bears against the cylinder head of the engine.
As shown, the heads A and A are cored to provide indzction and eXha' st ports and passages leading thereto and therefrom, and, as shown, the head A is provided on its inner side with a cored passage a, which leads from the ind;ctionport (1;, opening into the pres sure-chamber X, and along the side of said head and COIIlIIli' I1lG&t6S with a corresponding passage a in the head A, which opens from the inlet-port 0c in said head, which opens into the steam-chest. Acorresponding inlet-port x is provided diametrically opposite the inlet-port 0c and on the opposite side of the revolving head 13' and opens into the pressure-chamber X in the cylinder-head A. A passage a leads from said port to a port 00 which opens throi' gh the o1 ter face of the cylinder-head A into the steam-chest diametrically opposite the port 00.
Rigidly see red on the hub B of the revolving head l3 and atiording a gro" nd joint with the o' ter face of the cylinder-head A is a valve-disk D, provided, as shown, with three inlet-apert' res therethrotgh, which are arranged eqial distances apart and near the periphery to register with the ports 90 and 03 thro' gh the cylinder-head A. Said apertires are of a width corresponding with the radial length of the inlet-ports and of a length l versely of said rotating to permit inlet of the pressure fliiid against the abutment closely in advance thereof for nearly the entire length of the respective The pressure inlet or supply pipe 01 opens into the steam-chest formed in the head A bolted to the cylinder head A and chambered to contain the valvedisk D. i
Exhaust-ports d (1 open from the end of movenlent of the abutnients. The port d opens from the chamber X into a chamber (1 in the cylinder-head A and from which opens an exhaust-pipe d. The exhaust-port on the opposite of the enginenarr..ely, the ort d in the head Adischarges directly into the exhaust-pipe d, communicating through said head. Said exhaust-pipes may be con nected, if desired, in a single pipe or may dis charge to the atmosphere independently, as preferred.
Any suitable packing for the rotating head B may be employed. As shown, an annular strip of packing d is provided about the hub of the rotating head B and a gland (i is as shown in Fig. 2, thus preventing any escape of the pressure fluid except through the exhaustports. As shown, a pipe G, provided with a valve g, connects the induction or supply pipe with inlet-passages a, a, and a below the valve-disk D and perniits adniission ofthe to the pressure-chambers indepressure fluid pendently of said valve-disk.
'lhe operation is as follows: In starting the engine the pressure fluid is adniitted through the induction-pipe to the steamchest. .If the ports are both closed by the position of the'valvedisk D, as niay son..e times occur, the valve 9 in the pipe G is opened, adiritting pressure to one or both pressure-chambers and starting the engine. 'lhe valve 9 1r ay thenloe closed, and the steam or other pressure fluid will be adir. itted regularly and alternately through the oppositelydisposed ports 00 03 into the respective pressure-chamlt ers against the abutnients and the head B As the head B rotates, the abutnients B B, and B reciprocate transhead B first into the pressure-chamber X on one side of the head and then intothe pressure-chamher X at the opposite side thereof, taking pressure alternately on opposite sides of the head at diametrically opposite points, and inasmuch as there are three of said abutnients slidahly carried on the revolving head, two of these are at all tin. es subjected to pressure either direct or expansively. Said valve-ports through said valve-disk D are of such size and so arranged as to cut off the steam-supply after having filled the pressure-chamber behind one abutn' ent just tefore another receives direct pressure. 'Ihus forapart of the travel of each abutrnent the steam is acting each pressure-chamber in advance of the directly on the abutment by impact and for a portion of its travel is acting by expansion to drive the shaft. Inasnuch as said abutments are journaled to slide transversely of the head B on roller-bearings it is obvious that but slight friction can occur, and, furthermore, inasmuch as the ports are arranged at the points Where the abutments starts to move transversely of the head the pressure is relieved from the abutnients approxiir ately at the moment the transverse ILOVGll'BIll] begins and is not again applied until inlet-pressure is received on the opposite side of the rotating head. In this 11 anner the abutments reciprocate back and forward in the steam-chamber in one and then the other pressure-chamber thereof with but slight friction and, being carefully packed, with practically no loss of power.
Ooviously While I have shown a rotary valve-disk on the shaft it is obvious that other valves may be employed, if desired,
and that any suitable inlet or exhaust ports may be en ployed. I therefore do not purpose liniiting this application for patent otherwise than necessitated by the prior art, as many details of the construction and arrange1r ent n' aybe varied without departing from the principles of my invention.
