nal combustion, steam, air andother gas or' "vaporen'gines," of the annular or ring type which are moved axially. to uncov'erTthe inlet and exhaust ports in the cylinder walls and so control theadmission and emission of working fluid to' and: from the cylinder. The present invention hasfor its object to provide an improved arrangement of 'superposed or end-to-end valves.
According *to the invention "I employ a: plurality of ring valves arranged one elosew above the other at the top or at one end of the engine cylinder the interior surfaces of the valves forming a continuation of the interior surface of the cylinder, one of said valves seating upon the cylinder wall and the other valve or valves seating upon the next loWer valve, said valves controlling the inlet and exhaust ports opening directly into and out of the engine cylinder. I also provide mechanical means whereby one or more of said valves can be lifted 'or moved axially to uncover the inlet port or ports or the exhaust port or ports in the wall of the engine cylinder.
I will fully describe my invention with reference to the accompanying drawings wherein Figure 1 is a central vertical section of the head or upper portion of the cylinder of an internal-combustion engine fitted with my improved arrangement of ring valves and with one construction of means for operating same in accordance with my invention; and
Fig. 2, is a plan-on the line X-Y in Fig. 1. Referring to the drawings, a is the engine cylinder, 22 the piston, c the inlet for work ing fluid which opens into an annular chamber d in the cylinder casting, and e the outlet to exhaust which leads from an annular chamber 7 in the cylinder casting. In the embodiment of my invention illustrated in the drawings, I provide two valves 9, h each I of which comprises a complete ring, the internal diameter of whichis the same as that of-the engine cylinder a, and thus Is very slightly greater than the external diameter Specification ofLette rs I atcmt.

' of the piston 72. The interior surfaces of the ring valves 9 and IL form a continuation of the interior surface of the cylinder wall.
Theljoiver ring valve 72; is provided with an inclined or beveled under face j seating on a .beveledwfa'ce 70 around the cylinder, and .forms the wall between the'exhaust passage and'the interior of the engine cylinder a. 'lhe upperringvalve g is also provided with an inclined or beveled 'under face m and seats on the upper face n ofthe lower ring valve h which is similarly inclined.
The upper valve 9 formsthe wall between .the inlet passage J and the interior of the engine cylinder. The cylinder head 0 which carries the usual spark plug p, ,ismade so that it can be readily detached from the cylindercastinga; and, in order to render the upper ring valve 9 gasrtight, I provide a split junk or like packing ring or rings g arranged in an annular recess or groove 0'' in the cylinder head. While the under faces of the ring valves 9 and h are shown as being beveled, it will be obvious that, if desirable, the under faces of these valves may be horizontal or at right angles to the axes of the cylinder.
To open the engine cylinder (1 to working fluid or to exhaust the ring valves 9 and h are lifted off their seatings by rods s and t attached at diametrically opposite points to the ring valves 9 and h. In the arrangement illustrated in the drawings, the rods t, which are attached to the upper valve g, are hollow and surround the rods 8 attached to the lower valve k.
The rods 8 and t may be lifted at predetermined intervals by any convenient means. For example, and as shown in the drawings, the rods 8 project beyond the upper ends of the hollow rods t and are connected together by a cross bar a, the rods t being similarly connected together by a cross bar '0 which is cranked so that its center portion lies alongside the cross-bar u, said cross bars being alternately lifted by cams w, a: mounted side by side on a cam shaft 3 suitably driven from the crank shaft of the engine. Springs 2 are provided in boxes 2 to return the valves to normal position after they have been lifted, said springs being arranged between collars 3 on the rods 25 and inner ends of screw plugs 4 which close the boxes 2. It will be seen that, when the upper valve 9 is lifted, the
lower valve h is not moved and the inletpassage cl only is put into communication with the interior of the cylinder 0:,while, when the lower valve h is lifted, the upper valve g is also lifted with it, but the port in the cylinder Wall communicating with the inlet passage d is still covered by the valve h and the exhaust passage f only is putinto communication with the interior of the cylinder at. In some cases, instead of arranging the actuating rods 8 and t one withintheother readilyfitted, and, by removing the cylinder head, direct accesscan be had to the valves thus permitting easy repair. Moreover, a perfectly cylindrical combustion chamber is obtained, and, when-used with steam 'or air engines, a very small clearance space is required. I claim:
'1. A plurality of ring valves arranged one above the other at one end of an engine cylinder, the interior surfaces of the valves forming a continuation of the interior surface of the cylinder, one of the said valves seating upon the cylinder wall and the next superposed, said valves controlling the inlet and exhaust ports, opening directly into and out of the engine cylinder, substantially as herein described. a 'T 2. The combination with a plurality of end-to-end ring valves, of mechanical means for lifting said valves said means consisting of actuatingmods attached to the rear of the ring valves and passing through springloaded'boxes to the outside of the: engine cylinder, the rods attached to' each ring valve being coupled together. by a crossbar adapted to be lifted by a cam on a cam shaft operated from the crank shaftof theengine,
substantially as and for the purpose herein described.
