SPECIFICATION forming part of Letters Patent No. 683,399, dated September 24, 1901.
Application filed April 29, 1901- Serial NO- 58,026. (NO model.)
To all whom it may concern/.-
Be it known that 1, WILLIAM A. HILL, a citizen of the United States, residing at Rutland, in the county of Rutland, State of Vermont, have invented certain new and useful Improvements in Revolving Cylinder Engines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to a revolving-cylinder engine, and particularly to a structure wherein a plurality of cylinders are mounted upon a rotatable shaft and connected by piston-rods to a relatively fixed point, which is adapted to be shifted into positions eccentric to the axis of said shaft.
The invention has for an object to provide a structure of rotatable shaft carrying a plurality of pistons whereby the propelling medium shall be fed to the respective cylinders in succession and exhausted therefrom, so as to produce a continuous rotation of the shaft and cylinders carried thereby.
A further object of the invention is to provide means whereby a relatively fixed point of connection for the piston-rods from the cylinders may be shifted into positions either concentric to the axis of the rotating shaft of the cylinders or eccentric thereto when it is desired. to rotate said shaft.
A further object of the invention is to proing means adapted to operate within a steamchest having inlet and exhaust chambers, whereby the cylinders are fed directly from the shaft upon which they are mounted and numerous auxiliary connections obviated, thus simplifying the structure of engine and rendering the operation thereof direct and positive.
Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.
In the drawings, Figure 1 is a side elevation of an engine embodying this invention. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical section through the steam-chest of the engine. Fig. 4 is a similar section through the cylinders and driving-shaft. Fig. 5 is an enlarged horizontal section with parts broken away on the line 5 5 of Fig. 4; and Fig. 6 is a horizontal section on the line 6 6 of Fig. 4, showing the method of connecting the piston within the cylinder with its red.
Like letters of reference indicate like parts throughout the several figures of the draw ings.
The letter Adesignates a frame, which may be of any suitable construction and provided with a foundation-plate A. At the opposite ends of this frame bearing-boxes A are provided for the driving-shaft B and one end of this shaft with the usual driving-pulley B. The opposite end of the shaft is provided with a plurality of cylinders O, radially disposed to the shaft, as shown in Fig. 2.
Supported from the frame A is a stationary steam-chest D, through which the shaft 13 passes. This chest has at its upper portion an inlet-chamber D and at its lower portion an exhaust-chamber D separated by bridgewalls D at opposite sides, each being provided with a suitable packing. The inlet-chamber communicates with a suitable supply-pipe D for the motive power, while the exhaust-chamber communicates with an enlarged chamber D and an exhaust-pipe D leading therefrom. Within the steam-chamber a cut-off valve E is located, as will be more fully hereinafter described.
The shaft B is provided with a series of longitudinal channels B therein, corresponding in number with the cylinders carried at the end of the shaft B. These passages are closed throughout their length and provided with an opening B within the steam-chest,
which alternately communicates with the inlet and exhaust chambers.
Each of the cylinders O is provided with a passage C,communicating with the outer end thereof and extending from the shaft B, where they communicate with a passage B extending from the channels B to the passages C. The inner ends of the cylinders also communicate with these passages B by means of passages B as shown by dotted lines in Fig. 4, the arrangement of parts being such that the inlet-passage for any one cylinder communicates with the channel at the opposite side of the shaft B from that with which the exhaust-passage communicates. It will be understood that the cylinders and connections are firmly secured to the shaft and r0- tated therewith, while the inlet and exhaust of steam are entirely controlled by the movement of the shaft within the steam-chest, wherein one channel thereof alternately communicates with the inlet-chamber and with the opposite end of two cylinders.
Each of the cylinders is provided with a piston F, of any desired construction, adapted to be driven in one direction by the pressure of the motive power and to be restored to its initial position by its operative connection with the other parts of the engine, as the cutoff valve E determines the length of cut-01f and permits a direct steam-pressure in only onechannel at a time. Each of these pistons is connected with a piston-rod F by means of a stud F extending through the slotted wall at one side of the cylinder, which wall is providedwith guide-flanges O adapted to retain in position a cover-plate C through which the stud F passes and which plate forms a closure over the slot in the side of the cylinder. The stud F forms a wrist; pin connection at F for the piston rods or straps F, which at their opposite ends are pivotally mounted on a disk F in any suitable manner, as shown in Figs. 1 and 2. This disk is in turn rotatably mounted, as shown at F in Fig. 1, and its fixed point of support is carried by a slide F, suitably mounted in a standard A rising from the base A. This slide F is seated within any usual dovetailed recess of the standard, which is provided with a slot A adapted to receive a pin F", journaled in the slotted lever G at a point above the pivot G of said lever. The upper end of the lever G is provided with a handle G upon which a suitable latch mechanism G is supported and adapted to cooperate with a locking-segment G carried at the upper end of the standard for the purpose of retaining the disk in a position either concentric'or eccentric to the axis of the drivingshaft 13. I
In the operation of the engine the steam is admitted to the cylinder through the chest D, whence it passes through the channel B connecting passages B and B to the opposite ends of two of the cylinders O. The pistonrods from all of the cylinders are connected to the disk F which is shifted to a position eccentric to the axis of the shaft B, and the pressure of the motive power upon the piston drives or rotates the cylinder from this eccentric point, as is well known in this art. During this movement the passages 13 and B communicate with one of the channels B now upon the opposite face of the shaft from the feeding-channel and communicating with the exha'usit-chamberD of the steam-chest. This movement of the cylinder rotates the shaft B, bringing the openings B of the passages successively under the cut-off valve E, which is loosely mounted in the steam-inlet chamber and may be of any desired width to effect a cut-off at the desired length of travel for the piston. As soon as this cut-off closes the channel 13 the motive power is shut off from the cylinder just described and the piston returned therein to its initial position through its connection with the disk and in the movement of the successive similar operation of each of the pistons. In order that the operation of two opposite pistons may be clearly understood, the passages B and cylinders C in Fig. 4 have been respectively numbered 1, 2, 3, and 4, and 1, 2, 3, and 4. It will thus be seen that the steam from channel 1 enters the inner end of cylinder 1 through the passage B from the channel 1 and also the outer end of the directly opposite cylinder 3 through the passage B which also communicates with the channel 1 in the drivingshaft B. It will also be seen that the passages C and B from the cylinder 1 communicate with the channel 3 upon the exhaust side of the shaft B, and the opposite passage B from the inner end of the cylinder 3 also communicates with this channel 3, which acts as an exhaust. During such operations the cylinders 2 and 4: are being restored to theirinitial position, and in the progressive rotation of the parts the same operation occurs therein as described in connection with cylinders 1 and 3. In the reversal of the engine the passages 13 and 13 act in the directly opposite capacity from that heretofore described. This construction applies the power from the two cylinders simultaneously and at a single point, thus increasing the power and capacity of the engine. If it be desired to stop the rotation of the engine, the disk I may be shifted to a position concentric to the axis of the driving-shaft B, which will render all of the cylinders inoperative, as the force from the piston-rods will be applied in a direct line to the center. If the disk be shifted toward the opposite side of the axis, a reverse movement of the cylinders and shaft will be secured, and the feed to the cylinder will be likewise reversed.
It'will be obvious that the controlling-lever G may be shifted to various positions for use as a cut-off to shorten the stroke of the pistons or as a reverse-lever. In this reversing action and the consequent reversal in direction of rotation of the shaft G the cut-off valve E is carried by frictional contact with said shaft to the opposite side of the casing and there acts in the same capacity as before. It will be apparent that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims, while the number of cylinders may be varied at will or as found desirable and the connecting passages suitably multiplied or decreased to correspond with such changes in structure. It is also obvious that while the engine is shown as a stationary engine the same may be applied to a vehicle or other rotating machine wherein the rotation of the cylinders may be directly applied to a rotating member.
