Patented Sept. 29, 1908.
Application led April 18, 1907.. Serial No. 369,023,
To all whom it may concern:
Be it known that I, SAMUEL I-IAUDEN- SHIELD, a citizen of the United States of America, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rotary Engines, of which the following is a speciiication, reference being had therein to the accompanying drawing.
This invention relates to rotary engines, and the invention has Vfor its object to provide a novel reversible engine from which a maximum amount of eiiiciency can be obtained, with a minimum expenditure of fuel.
My invention aims to provide an engine having an eccentrically mounted revoluble head, provided with a plurality of radially disposed pistons which can be easily and quickly adjusted to compensate for the Wear and tear of the pistons withoutremoving the pistons from the engine. In this connection,`
have devised a novel packingfor the pistons whereby the engine can be economically operated to obtain the highest degree of efficiency from an engine ofthe above type. i
The detail construction,V entering into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims, andreferring to the drawing forming part of this specification, like numerals of reference designate corresponding parts throughout the several views, in which p Figure 1 is a longitudinal sectional view of my improved engine, Fig. 2 is a crosssectional view ofthe detachable'plate, of the engine, Fig. 3 is an elevation ofthe same, Fig. 4 is a plan of the steam chest, Figs. 5, 6 and 7 are perspective views of a acking used in connection with the engine, 8 is an elevation of the revoluble head of the engine, Fig. 9 is a cross sectional view of the same, Fig. 10

To put my invention into practice, Iconstruct my improved engine, of a cylindrical casing 1 supported upon a base or suitable foundation 2. formed an enlargement 3 terminating in a steam chest 4, which communicates with the bore 5 or interior of the casing, 1, by vertically disposed inlet ports 6--6, said ports being arranged in the ends of the enlargement 3. The steam chest 4 is closed by a plate 7, suitable packing 8 being interposed between the plate 7 and the top of the chest 4. Connected with the plate 7 is a steam inlet pipe 9.
Arranged within the steam chest 4 are two slide valves 10, said valves controlling the inlet of steam to the ports 6 and 6a. The valves are carried bya rod 1 1 slidablymount- 4ed in the steam chest 4 and in a bracket 12 provided therefor in said chest. The outer end of the rod 11 is connected to an operating lever 14 suspended from a bracket 15 carried bythe` plate 7. The steam chest is provided with a segment-shaped gage 16 for determining the position of the lever 14.
The 4base or foundation 2 of the engine is provided with two horizontally disposed exhaust ports 17 and 17a communicating with vertically disposed ports 18. These ports can be connected together by a pipe leading to a suitable point of exhaust. The horizontal exhaust ports 17 and 17et are formed in the sides of the base 2 and communicate with the bore 5 of the casing 1, said ports communicating with the bore at two points ninety degrees apart. In the ports 17 and 17a are slidably mounted valves 19, the valve stems 20 of which extend outside of the base 2 and connect with links 21 and 22. The link 21 is connected to the crank arm 23 of ashaft 24, j ournaled in a bracket25 carried by the side of thecasing 1. The shaft 24 is provided with a crank arm 26, connecting by a rod 27 with the crank arm 28 of a shaft 29 located upon the opposite slide of the engine, said shaft being j ournaled in a bracket 30 carried by the base 2. Connected to the shaft 29 is an operating lever 31, to which the link 22 .is connected, said lever being provided with a movable locking pawl 32 adapted to engage in a notched bar 33, carried by the base 2 of the engine.
The valves 10 and 19 are actuated by t'he Vlevers 14 and 31 respectively to reverse the engine, the ports 6 and17 being closed when the engine is operated in one direction, as in the direction ofthe arrow of Fig. 1 of the drawings, while the ports 6a and 17a are Upon the top of the casing is closed when the engine is operated in the opposite direction.
The casing 1 is provided with detachable side plates 34, said plates being secured by nuts 35 to stud bolts 36 carried by the edges of the casing 1. rhe plates are formed with central enlargements 37 upon their outer sides and with seats 38 in their inner sides, said seats carrying tapering annular blocks 39, which are adjusted in their seats by screws 40 and locked therein by screw bolts 41. The objectA of the tapering annular blocks will presently appear.
Journaled in the enlargements 37 of the plates 34, and transversely of the casing 1, is
a drive shaft 42 said shaft being eccentrically arranged with respect to the axis of the casing 1, to support a head 43, mounted concentrically upon the shaft 42, within the casing 1. Since the head is of a less diameter than the bore 5 of the casing 1 and is eccentric with relation to said casing, a crescentshaped compartment is formed between the periphery of the head 43 and the inner sides of the bore 5, this compartment conveying steam from the inlet ports to the exhaust ports.
The head 43 is formed with a web 44 having annular packing grooves 45 formed therein in which packing is located to engage the tapering annular blocks 39 of the plates 34 and form a steam tight connection. The head 43 is provided with radially disposed slots 46 for pistons 47, the confronting outer edges of said slots and the edges of said head being provided. with packing grooves 48 and 49 within which suitable packing is arranged to insure a steam-tight connection between the pistons 47 and the outer edges of the slots 46, and the edges of the head 43 and the plates 34, respectively.
The pistons 47 are grooved, as at 50 to receive packing strips 51 and 52, the latter being supported by springs 53, arranged in sockets 54 formed inthe strips 52 and in the pistons 47. The packing strips 51 are adapted to engage the inner sides of the bore 5, while the packing strips 52 engage the plates 34, during the rotation of the head 4T. The springs 53 serve to hold the packing strips 52 in engagement with the plates 34, the upper ends of the strips elevating the packing strips 51 and retaining said strips in engagement with the inner sides of the bore 5 of the casing 1. The pistons are provided with depending shanks 55 carrying trunnions 56 for segmentshaped actuating arms 57, said arms being arranged upon both sides of the web 54 of the head 43 and engaging the tapering annular blocks 39 of the engine.
The enlargement 3 of the engine between the inlet ports 6 and 6ad is provided with a recess 58 for a packing block 59, said block being adjusted by screws 60 passing through the sides of the steam chest 4, and engaging the packing block 59. T he packing block is recessed, as at 6l, to accommodate a roller 62, said roller bearing against the periphery of the head 43 and being retained in said packing block by packing strips 63, these strips also engaging the periphery of the head 43.
provide the inner sides of the bore 5 of the casing 1 with grooves 64, said grooves extending from the inlet ports 6 and 6 to within close proximity to the exhaust ports l17 and 17a. These grooves, being open to the crescent-shaped conipartment, form steam passages which permit of communication between the steam chambers on opposite sides of the piston, and being also in communica tion with the inlet port, provide means whereby the inlet ports cannot be closed or cut-off by the pistons, so that there is no pos sibility of the head stopping in such a position as would prevent its being started again as soon as steam is introduced through the inlet port.
The casing 1 is provided with lubricant receptacles for feeding the lubricant to the bore 5 of the casing 1, thus insuring easy rotation of the head 43 within the casing.
Operation: With the valves 1() and 19 in the positions shown in Fig. 1 of the drawings, steam entering the chest 4 passes through the port 61 and enters the e1'escent-shaped compartment of the bore 5, where it impinges against the first piston which lies within that portion of the compartment extending between the steam inlet and exhaust ports, thereby causing the piston and head to rotate until the piston passes the port 17L at which time the steam behind the piston ex hausts, but in the mean time another-piston has taken steam from the port 6u. lt will thus be observed that the steam traverses rnactically one-half of the casing 1 before exhausting, thus obtaining full use of the steam before its final escape.
As shown, the annular tapering blocks are arranged with their peripheries concentric with respect to the inner surface of the bore 5 but eccentrically to the shaft 12, therelore, during the propelling of the head 43 by the steam-impelled pistons 47, the pistons will remain in contact with both the inner face of the casing and the periphery of the blocks, the eccentric mounting of the head causing the pistons to have a relative in and out movement within the slots 46.
As the surface of the piston actuating arms wears, the blocks 39 can be moved inwardly, to insure a positive operation of said arms and the pistons 47. This is a distinct feature of my invention to which l attach considerable importance.
It is thought that the operation of my improved engine will be fully understood without further description, and while l have herein disclosed the preferable construction feeders l of the engine, I desireitto bey understood that suchchanges in the size, proportion and minor details of construction as are ,permissible by the appended claims,may1be resorted to Without departing from the spirit and scopeof the invention. Y a
It Will be understood thatlalthough I have herein described my engine Voperating With steam power, any other motive force such as hydraulic, compressed air, orthe like may be employed. y y
