Specification of Reissued Letters Patent.

Reissued April 9, 1907.

To all whom it may concern.

Be it known that I, JAMEs LOGKE STRICK- LAND, a subject of the King of Great Britain, residing at \Vestport, county of Digby, in the Province of Nova Scotia, Canada, have'invention consists of the construction, combi nation, and arrangement of parts, as herein illustrated, described, and claimed.

In the accompanying drawings, forming part of this application, I have illustrated one form of embodiment of my invention, in which drawings similar reference characters designate correspondin parts, and in which Figure 1 is a side e evation. Fig. 2 is a plan view. Fig.3 is a vertical transverse section showing the interior construction of the cylinders and the arrangement of the pistons. Fig. 4 is a longitudinal vertical section through the cylinders, showing the pistons in elevation. Fig. 5 is a vertical section on line 5 5 of Fig. 4 looking in the direction indicated by the arrow. Fig. 6 is a fragmentary detail, in side elevation, showing the bearing for one side of the cylinders and the piston-shaft. Fig. 7 is a vertical section on line 7 7 of Fig.

' 6 looking in the direction indicated by the ar rows. Fig. 8 is an elevation of the four pis tons used in the engine. Fig. 9 is a vertical section takenon line 9 9 of Fig. 2 looking in the direction indicated by the arrow. Fig. 10 is a plan view of the main bearing of the engine, showing the arrangement of cylinders on Fig. 1 1 is a fragmentary, detail, in front elevation, of one of the pistoneach side thereof.

heads. Fig. 12 is an edge elevation of one of the piston-heads, the packing being removed; and Fig. 13 isa vertical section through the steam-chest of the engine.

Referring to the drawings, 1 designatesa bed-plate havin on one end a bearin 2. Disposed in the Iiearing 2 is a main sha t 3, which is also supported by the main bearing 4, carried by the bed-plate 1. Disposed on the opposite sides of the main bearing 4 are cylinders 5 and 6, and dis osed above the main bearing is a steam-c est 7, having a supply-pipe 8.

The steam-chest is provided with a plurality of ports 9, to which are connected the pipes 10 and 11, the pi e 10 connecting with the cylinder 5 and t e pipe 11 connecting with the cylinder 6. The steamchest7 is provided with an exhaust-port 12, to which is connected an exhaust-pipe 13. Disposedin the steam-chest is a slide-valve 14, adapted to cover one of the outlet-ports 9 and the exhaust-port 12 and has connected thereto a valve-rod 15 for the purpose of actuating the valve to the desired position.

Disposed in the cylinder 5 is a cylinder 16, and disposed in the cylinder 6 is a cylinder 17, suitable packing-rings 18 being disposed around each of the cylinders 16 and 17 to make a steam-tight connection. Disposed in each of the cylinders 5 and 6 are springs 19, adapted to thrust against the inner ends of the cylinders 16 and 17 so that a slight play is permitted. Connecting the cylinders 5 and 6 is a ring 20, having passages 21 communicating with the cylinders '16 and 17 and having elongated slots 22 communicating with the passages 21. Secured on the shaft 3 is a p ate 23 provided with four slots 25, communicat ing with radially-disposed steam-passages 26. Secured to the plate. 23 are a plurality of disks 27, connected by webs 28, provided with chambers 29, forming the cylinders of the engine. Adjacent the outer ends of the chamber 29 are openings 30, communicating with the passages 26, suitable packing 31 being placed round each opening intermediate of the disks 27 and the plate 23. Disposed on the side of one of the disks 27 opposite to the plate 23 is a disk 32, suitable packing 33 being interposed between the disk 27 and the disk 32 to make a steam-tight fitting. The disk 32 is provided with a flange 34 and provided with an opening 27 in the adjacent disk 27, in which opening 35 is disposed a bearing 36, secured by bolts 37 to a edestal 38, which pedestal is disposed on t e bedplate 1. Disposed through the bearin 36 is a steam-pipe 39, connecting with the oiler and an exhaust-pipe 39*, and a suitable packing-ring 40'is disposed between the bearing 36 and the flange 34 of the outside disk 32.

Carried by the bearing 36 and projecting 29 is a pistonwithin the space between the disks- '27 is a shaft 41. Dis osed in each of the chambers ffead 42, and each piston-head has secured thereto a rod 43, the end of which is pivotally mounted on the shaft 41. The chambers 29 are preferably square in crosssection and each of the piston-heads 42 comprises the plates 44, (see Figs. 11 and 12,) between which are disposed four movable sections 45, of packing, the packing being actuated outwardly against the sides of the chambers 29 by means of the helical springs 46, whose inner ends are dis osed in openings 47 in the squared outer en s of the rods 43.

Rotation of the shaft 3 is produced by pressure of the steam against the sides of the chambers 29, the area of the chambers being different, owing to the disposition of the piston-heads 42, the shaft 41 being placed eccentric to the shaft 3. 7

Steam being admitted through the pipe 1 1, it passes into the cylinder 6, thence through one of the passages 21 and one of the slots 22 into one of the steam-passages26, and thence into one of the chambers 29, causing rotation of the cylinders 29 and the consequent oscillation of the piston-heads 42, which are secured to the shaft 41. Steam is exhausted from the cylinder 29 through the passage 26, out of the slots 22 and into the cylinder 5, and from thence to the steam-chest. When one pair of the slots 25 register with the slots 22, steam is admitted to the chambers 29, and rotation of the cylinders in one direction is caused, so that if the slide-valve 14 is moved to cover the opposite port 9 the steam will be admitted through the pipe uncovered, and the movement of the cylinders 29 will be reversed. When steam is admitted through the cylinder 5 into the cylinders 29 through the assages described, it should be understoo that theexhanust is through the corresponding passages on. the exhaust side and into the cylinder 6, the slots 22 being two in number and being placed in the same horizontal plane, the passages 26 leading to the cylinders 29 being successively uncovered by rotation of the parts. The shaft 31 being placed eccentric to the shaft 3 and the disks 27 being revolved with the shaft 3, it is evident that the piston-heads 42 must be oscillated by this movement, thereby-changing the area of the chambers on which the steam exerts power. The thrust of the steam against the plates 27 being toward the left hand of Fig. 1, steam from the boiler is admitted'through the pipe 39 to counterbalance the thrust, and the pipe 39 permits the exhaust of this steam when the steam in the cylinders 29 is exhausted, the friction of'the thrust being materially lessened by this relief.
