Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed September 1. 1905. Serial No. 276,666.

To all wh/om it may concern;

Be it known that I, WIN I). WILLIAMS, a citizen of the United States, residinflr at Phila delphia, in the County 0f Philadephia and AState of Penns lvania, have invented certain new and useu Improvements in Rotary Oscillatory Reciprocating Engines, of which the following is a specification.

In the generation andutilization of artifi cial forces many have been the attempts to obtain a maximum amount of units of available force from the energy developed by the combustion of fuel. It is known that in the o eration of reciprocating engines only a portion of the force of the fluid medium is utilized/i. e., that which acts on the piston to drive it-the remainder acting on the cylinder-head, which is inert and immovable. This difiiculty has been met by utilizing two pistons and admitting the motive medium etween them and harnessing the force represented by each. No real advantage results from this construction because the sum of the strokes of each piston may be represented b the single stroke of a piston of like area. o this end the engine in operation is the resultant of a reciprocating, an oscillatory, and a rotar movement, all combining in the economica conservation of energy.

The mechanical embodiment of the invention consists of a frame, a relatively rotatable head, an oscillatory engine, a crank-wheel between the engine and rotary head and geared to the frame so as to e'ect rotation of the said rotary head and an oscillation of the en ine, and 'a valve mechanism for admitting an exhausting the motive medium from the en Ine.

or a full description of the invention and the merits vthereo and also to acquire va knowledge of .the details of construction of the means for effecting the result reference is to be had to the following description and ac- -com anying drawings.

'le the invention may be adapted to different forms and conditions by changes in the structure and minor details without clepartin from the spirit or essential features thereo still the preferred embodiment is shown in the accompanying drawings, in which- Figure 1 is a vertical transverse section of an engine embodying the invention about on the line :u :v of Fig. 2. Fig. 2 is a vertical longitudinal section of the engine on the line y y of Fig. 1. 3 is a side view of the engme having a portion broken away to show Inore clearly the relation of the steam passa es and ports. Fig. 4 is a View similar to Fig. 3 of the opposite side of the engine. Fig. 5 is a section of the engine on the line z z of Fig. 2. Fig. 6 is a detail view of the engine and crankwheel, showing the disposition of the orts when the piston is at one-half of its stro e in one direction. Fig. 7 is a view similar to Fig. 6, showing the relation of the parts when the piston is at one-half of its stroke in the opposite direction. Fig. 8 is a detail view of a portion of the cylinder and a plate, showing the cooperating ports.

Corresponding and vlike parts are referred to in the following description and indicated in all the views o? the drawings by the same reference characters.

The main frame of the engine comprises a base 1, heads 2, and a rim or shell 3, the latter preferably having a close it with the heads and provided upon its inner circumference, which lis circular, with cog-teeth 4. The superstructure of the frame constitutes a casing in which the rotary head, engine, and adjunctive parts are located and housed. The heads 2 are reinforced u on their exterior by means of ribs 5, whic have a radial arrangement, and said heads have bosses'at their center to provide bearings in which the shaft of' the engine is mounted.

The engine and cooperating crank-wheel are mounted upon a rotary head which is located within the casing or u per part of the main frame. I he engine is o the oscillatory reciprocating type and comprises a cylinder 6 and piston 7, the piston-rod operating in a stufiing-box 8, closin the open end of the cylinder and having goose connection with the crank-wheel 9 by means of a wrist-pin 10 in the manner well understood. The pivotal end of the cylinder 6 is thickened and formed with a transverse o enin in'which is fitted the pivot 11, upon wh mounted for oscillatory movement, said pivot beimT stationary and made hollow and subdivided by a longitudinal partition 12 to form passages 13 and 14. Openings 15 and 16 are formed at diametrically opposite points of the pivot 11 upon one side of the partition 12, and an opening 17 is formed in a side of the pivot adjacent' to the partition 12 and opening 16. The several openings 15,

ich t e engine is' ICO 16, and 17 constitute steam-ports. An open- L infy 18 is provided in the outer end of the cyl; inder, and a corresponding opening 19 1s lo- :ated at the inner end, both openings 18 and 19 being at diametrically opposite points and leading from the transverse opening in which the pivot 1 1 is fitted. At the op osite end oi' the cylinder a triangular-shaped3 space 20 is formed in a side wall, and

ports

21 and 22 lead therefrom through opposite sides of said wall, said

ports

21 and 22 having a right-angular disposition, the outer port 21 being lengthwise of the cylinder and the inner port 22 transverse thereof and in communication with the wider end of the space 20. The port 21 is adapted to 'alternately register with

ports

23 and 24, formed in a wall of the rotary head, so as to admit steam into the inner end of the cylinder and exhaust it therefrom. A live-steam passage 25 is formed in a wall of the rotary head and establishes communication between an end o the pivot 11 and the live-steam ports, and a corresponding passage 26 is in communication with the exhaust-ports to carr off the spent steam. As the engine oscil ates the port 21 thereof' alternately connects with the ive and exhaust ports in the well-known manner to admit ot supplying steam to the cylinder to drive the piston toward the pivotal end .of the engine and to exhaust the spent steam as the piston is driven inward or away from the pivotal end of the engine.

The rotary head, which carries the engine and crank-wheel, may be of any construction and preferably comprises companion plates 27, which are connected by transverse tiebolts 28, the ends of which are reduced and threaded to pass through corresponding openingsof the plate. The pivot 11 is constructed similar to a tie-bolt 28 and performs the same oiiice--that is, to connect the plates 27. A passage 29 is formed in one of the plates 27 and is in communication at one end with the passage 14 of the pivot 11 and at its opposite end with the opening 30, formed longitudinally in an end portion of the shaft 31 of the engine, and which is in communication with a pipe 32 for supplying steam or other fluid motive medium for driving the engine. The engine is mounted between the plates 27, and the outer end of the piston-rod is connected with a transverse rod which corresponds to the wrist-pin 10 and which connects a pair of crank-wheels 9, each being mounted upon journals 33, extended inward from the plates 27. The crank-wheels 9 are toothed around their periphery and mesh with the cog-teeth 4 upon the inner circumference of the rim 3. In the operation of the engine as the piston is driven inward or away from the pivotal end of the engine and by reason of its toothed connection with the stationary frame bers of the head carrying said crank-wheel and engine is caused to turn.

Having thus described the invention, what is claimed as new is 1. In combination, a stationary frame, a rotary head comprising spaced members, an oscillatory engine mounted between the members of said head, a hollow pivot supporting said engine and subdivided into longitudinal assages which communicate at opposite en s with passages formed in the memthe rotary head, and a crank-wheel mounted upon said rotary head and operatively connected with the piston-rod and geared to the stationary frame to effect rotation of the head in the operation of the engine.

2. In combination, a stationary frame, a rotary head comprising spaced members each provided with a steam-passage, a hollow pivot connecting said members and having communication at its ends with the passages in the members of said rotary head, said pivot being subdivided longitudinally to provide live and exhaust passages, an oscillating engine mounted upon said valve, a crank-wheel connected with the piston-rod and co erating gearing crank-wheel and enginerame.

3. In combination, a frame comprising a casing, a rotary head housed within said casing and comprising spaced members, each provided with a radially-disposed passage, a hollow pivot having communication at opposite ends with the passages of said members, an oscillating engine mounted upon said hollow pivot, companion crank-wheels journaled to the rotary head and operatively connected with the piston-rod, and cooperative gearing between the crank-wheels and rim of said casing.

4. An engine comprising a cylinder and a piston arranged to reciprocate therein, a rotary support having the engine cylinder mounted thereon for oscillatory movement, a toothed crank-wheel mounted upon said rotary support and having the piston-rod connected thereto, and a toothed rim having the toothed crank-wheel coperating therewith and having its center coinciding with the axis of the aforesaid rotary support, the axes of the engine-cylinder and crank-wheel being upon opposite sides of the axis of the rotary support and in the same straight line therewith.

In testimony whereof I affix my signature in presence of two witnesses.

WIN D. WILLIAMS.
