SPECIFICATION formingpart of Letters Patent No. 682,389, dated September 10, 1901. Application filed January 22, 1901. Serial No. 44,266. (No model.)

ject the furnishing of a compact machine in I which a single lever controls the starting, stopping, reversing, or running of the engine at any speed and without the aid of the usual eccentrics or links.

It consists in the combination, in an engine having its cylinders radially disposed in relation to a main power-shaft, of oscillating inlet-valves at the outer ends of these cylinders, a governing device by which said oscillation is effected, a controlling-valve in relation to each of said inlet-valves, and means bywhich said controlling-valves are operated 1n unison.

It also consists of details which will be more fully hereinafter set forth.

In the accompanying drawings, Figure 1 shows the inlet and reversing valves with connections detached from one another. Fig. 2 is a vertical central section through the engines. Fig. 3 is a partial section through the upper parts of the engines on line yyof Fig. 4 and at right angles to Fig. 2. Fig. 4; is a cross-section through the engine-head on line a: .90 of Fig. 3.

Having reference to the drawings, F represents the frame of my engine. The cylinders '22 are cast integral with this frame. In these cylinders are the pistons, to which are pivoted the piston-rods 23. The latter are ad- .justably connected to the crank in the main shaft 5 by means of the rings or straps 25'. j Each rod is provided with aprojection or foot 24, and the rings 25 rest upon these projec;

Steam is conveyed to the cylinder through passages 26, formed in the jacket" surrounding the cylinders.

At the outer ends of the cylinders are situated the rotatable inlet-valves G. Each of these valves consists of a cylinder having a longitudinal diaphragm g, ports 29 on either side of the diaphragm, radial end ports 31, and a stem 27 at the other end of the valve Similar valves (Z are arranged in relation to the other cylinders. These valves d d are each provided with a central end opening or chamber33. ing through one side of the valve is the eX- haust-port 33. Opposite the port 33 is the inlet-port 32, adapted to register with the steamsupplypassage 26. A U-shaped partition 32 incloses this inlet-port and cuts 01f communication with the chamber 33 and forms a radial passage 32, which is adapted to regis- Communicating with this open-' ter with one or other of the ports 22 of the partition. These latter ports communicate, as before stated, with the valves G, governing the supply and exhaust to the cylinders. The controlling-valves cl d are operated in unison to start, stop, or reverse the engine by means of a single lever E. This lever is secured to one of the valves, as d, and connects with the others by means of links 36 and crank-arms d" on the valve-stem (1 The live steam enters the feed-passage 26 through the opening 35 and around the valveseats 34. From the passage 26 it is admitted to the cylinders through the port 32, passage 32, and one or the other of the ports 22 and corresponding ports 31, 29, and 30. The exhaust will take place through the opposite of the ports 29, 31, and .22 into the valve-chamber 33 and out through the port- 33.

The oscillation of the inlet-valves G is done i in the following manner: A fiyrwheel 37 is carried upon the end of the shaft 5 of the engine. Upon the spokes of this wheel is attached a flange consisting of two conjoined i concentric crescents of unequal radiusa larger 38 and a smaller 39. The former is slotted, so as to allow a crescent lever 4:0, pivoted at ll, to swing therein. Oppositelly upon the inner side of the crescent 39 is attached a spring 47, carrying a Weight 4-2, which is connected'with the lever 40 by a link 43. The

- cranks 28, above referred to, upon the stems of the valves G are held in proper position by means of rods or links 44, connected to springs or dashpots 45. Steam is only admitted through these valves G and to the cylinders as the crescent lever 40 in the revolution of the fly-wheel strikes a roller 46 upon a crank, lifts the crank, and accordingly rotates the valve. The momentthecrescentleverpasses from that roller its dash-pot causes the valve immediately to close and shut off the live steam and permit exhaust at the proper instant. The crescent lever protrudes more or less beyond the slot in the flange, according to the speed of the fly-wheel and the centrif 'ugal action of the weight-governor.

Consequently the faster the engine runs the less will the lever project and the less will be its effect on the inlet-valves and the greater the tendency to cut off the steam, and-vice versa.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. .An engine consisting in combination of a plurality of fixed cylinders, pistons reciprocating therein and acting upon a shaft, os-' cillating inlet-valves at the outer ends of said cylinders, means by which such oscillation is efiected, a. rotatable controlling-valve adja-l cent to each of said inlet-valves, an inlet and; an exhaust port in the end of each control-- ling-valve, inlet and exhaust ports in the end of each of said first-named valves, means whereby said ports are adapted properly to register, and means whereby said controlling-1 valves are operated simultaneously to admit or'shut off steam to the cylinders.

2. An engine consisting in combination of.

a plurality of radially-disposed cylinders in the same plane, pistons therein, piston-rods connecting with the crank of a main shaft, said piston-rods having segmental portions bearing upon said shaft and held thereto by straps or rings, oscillating inlet-valves at the outer ends of said cylinders and means for effecting said oscillation, rotatable controlling-valves in axial alinement with said oscillating Valves, connections between said oscillating and controlling valves and a lever mechanism whereby said controlling-valves are operated to admit or shut oif steam to or from the cylinders.

. 3. In an engine and in combination with a cylinder thereof, a rotatable inlet-valve consisting of a cylindrical structure havinga lougitudinal diaphragm, slots on either side of said diaphragm and adapted to register with the port of said cylinder and radial slots at one end of said valve and on either side of said diaphragm.

4. In an engine and in combination with the steam-supply passage thereof, a controllingvalve having a hollowed or chambered end portion, an opening in the wall of said valve into said chamber, a second opening in the wall of said valve and adapted to register with said supply-passage, and radial partitions inclosing said second opening whereby plates or partitions against which the oscil-' lating valves abut, radial slots in said partition with which the ports in the end of said valves are adapted to register, and acontrolling-valve in relation to each of said oscillating valves, said controlling-valve having one end abutting against said slotted partition, admission and exhaust ports in said controlling-valve and adapted to register with the slots in said partitions, and means by Which said controlling-valves are rotated in unison to start, stop-or reverse the engine.

6. In an engine having radially-disposed cylinders, the combination with oscillating inlet-valves at the outer end of said cylinders, of a governor consisting of two conjoined concentric crescents of unequal radius upon the spokes of the fly-wheel, the larger crescent having a slot in which a crescent lever is fulcrumed and movable to or from the center of the wheel, means by which this lever is drawn inwardly by the more rapid revolution of the wheel, and conversely swung outwardly by the slowing of the wheel, and means by which this lever operates to open the inlet-valves on the revolution of the wheel.

7. The combination in an engine having a plurality of radially-disposed fixed cylinders, of rotatable inlet-valves in the outer ends of said cylinders, stems upon these valves protruding through the casing,cranks upon these stems, and means by which the valves are kept closed, of a governor upon the fiy-wheel on the engine-shaft, said governor consisting of two conjoined concentric crescents of unequal radius upon the spokes of the wheel, the larger crescent having a slot in which is fulcrumed a crescent lever, andwhich appears or disappears within the crescent by the revolution of the. wheel, said appearance and disappearance being controlled by a contrifugally-operating weight upon the wheel, said lever adapted to engage with each of the above-mentioned valve-cranks successively in the revolution of the wheel, whereby the said valves are rotated and steam admitted to the cylinders during such engagement of the lever and cranks.

In witness whereof I have hereunto set my hand.
