JosIAn'c}FLEMING,orxnnrnoir, MICHIGAN, ASSIGNOR TO DETROIT HOIST & MACHINE COMPANY, OFVDETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.
FLUID-PRESSURE ENGINE No. 923,16 I
To all whom it may concern:
Be it known that I, JOSIAH C. FLEMING,
a citizen of the United States of America,
residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Fluid-Pres sureflEngines, of which the following is a specification, reference being had therein to the accompanying drawings.
' The invention relates particularly to a controlling valve for fluid pressure engines, and consists inth'e novel and simple construction of the valve, and in the peculiar combination I and arrangement of its various parts as here mafter described.
In the drawings illustrating theinvention,
I Figure lis a vertical central section through the valve and a portion of an engine casing; Fig. 2*is a horizontal section taken on line of Fig.;1; and Fig. 3 is a perspective view of the valveand'its seat, the parts being detached to more clearly illustrate the respective constructions.
, In the drawings thus briefly described, A represents the casing of an engine, which may be of the oscillating type. B is a seat formed thereon, provided with a central bore or recess 0, and a plurality of ports ex gme. The construction of the engine is such that fluid pressure,--preferably air in this instance,-'-when admitted to either of the ports 0 (2, passes through the engine, thereby operating the same, and, exhausts through the other port, the engine thereby operating "in o'nedirection, and it will be obvious for reversing movement the air or other fluid pressure may be passed in the opposite d1rec- O tion through the ports mentioned.
D represents a disk, valve for controlling the portsmounted upon the seat for rotative oscillation] It is centrally bored, as at e, to register with the bore 0 in'theseat, and its *under o'r'meeting face is provided with a concavity'or recess f, so proportioned as to bridge over and thereby connect either of the ports 0 d with the exhaust b.
Specification of Letters Patent. Application filed June 3, 1908. Serial No. 436,386.
'mitting relative axial movement.
Patented June 1, 1909.
E represents a centrally apertured recessed cap, bolted upon the seatover the valve and spaced from the latter to form an opening, as g, permitting the air pressure to act upon the valve and hold it to its seat. The valve is also made in segmental form, as indicated, and adapted to be positioned, as shownin Fig 2, so as to constantly expose the inlet port a, allowing the air or other fluid pressure to fill the chamber formed by the recessed cap.
G indicates an operating stem for the valve extending through a suitable stufling box "L in the cap opening, entirely through the valve, as shown in Fig. 1, and partly within the bore in the seat. A shoulder,- preferably in the form of a collar, as h,-is formed upon the stem, which bears against the top of the valve and limits the amount of extension of the stem within the seat bore.
In order that the valve may properly seat at all times, the stem as shown is independent of it, and the bore in the valve and in the seat is of slightly greater diameter than that of the stem, so that there will be a loose fit between the parts for the purpose set forth.
An operative connection is formed between the stem and valve, holding the parts against relative rotary movement but per- The preferable connection is in the form of a key, as 7c, carried by the stem below the collar, which engages a suitable keyway Z formed in the valve.
The stem may be operated by any suitable handle or lever mechanism, and for this purpose its upper or free end is threaded, as at m, to receive the operating member.
In the operation, the valve being in the position shown in Fig. 2, the engine is at rest, the disk valve covering the complementary ports 0 d and the concavity f extending over the exhaust. Upon shifting the valve so as to connect through the concavity either of the ports 0 d with the exhaust, the remaining port will be exposed, permitting the air or other fluid pressure to pass therethrough from the inlet and to discharge through the complementary port and exhaust into the port 6, the engine thereby operating in one direction. To reverse, the valve is shifted in an opposite direction, causing the fluid pressure to pass in the reverse direction, through the ports 0 d, and exhaust in the same manner through the port I).
What I claim as my invention is,
1. In a fluid pressure engine, the combination with a ported valve seat provided with a central bore, of a rotatively oscillating disk valve thereon controlling the ports and having a stern opening extending centrally therethrough, a recessed cap upon the seat inclosing the valve, an operating stern for said valve extending through the casing, loosely through the valve and into engagement with its seat, and an operative connection between the valve and stem, permitting relative axial movement between the parts.
2. In a fluid pressure engine, the combination with the valve seat provided with a central bore, and a circular series of ports extending therethrough comprising an inlet and an exhaust oppositely disposed, and complementary ports intermediate the firstmentioned ports leading within the engine, a segmental disk valve mounted upon the seat for rotative oscillation having a concavity formed in its contacting face proportioned to connect either of the complementary ports with the exhaust, a recessed cap upon the seat inclosing the valve and spaced from the latter, an operating stem extending through the casing and loosely through and beyond the valve into the seat bore, and an operative connection between the stem and valve permitting relative axial movement between the parts 3. In a fluid pressure engine, the combination with the valve seat provided with a central bore, and a circular series of ports extending therethrough comprising an inlet and an exhaust oppositely disposed, and complementary ports intermediate the first mentioned orts leading within the engine, a segmentcl disk valve mounted upon the seat for rotative oscillation having a concavity formed in its contacting face proportioned to connect either of the complementary ports with the exhaust, a recessed cap upon the seat inclosing the valves and spaced from the latter, an operating stem extending through the casing and loosely through and beyond the valve into the seat bore, a collar on said stem fitting the recess in said cap and bearing against the top of the valve to limit the inward movement of the stem, and an operative connection be tween said stem and valve adapted to hold the parts against relative rotary movement while permitting relative axial movement between the parts, said connection comprising a keyway on a key loosely engaging said keyway.
In testimony whereof I aflix my signature in presence of two witnesses.
