SPECIFICATION forming part of Letters Patent No. 710,769, dated October 7, 1902.
Application filed January 13, 1902. Serial No. 89,422. (No model.)
To all whom it Duty concern.-
Be it known that 1, WILLIAM '1. FOX, of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Motors; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.
My present invention relates to motors 0perated by steam or other fluid and particularly adapted for propelling vehicles, boats, and the like; and it consists in certain improvements and constructions which render the same simple and easily constructed, and the parts being interchangeable the motor may be assembled by unskilled operators or taken apart for repairs, all as will be hereinafter fully described and the novel features pointed out in the claims at the end of the specification.
In the drawings, Figure 1 is aview of a' motor constructed in accordance with my invention, showing some of the steam-passages in section, said section being taken on the line a a of Fig. 3. Fig. 2 is a vertical sectional view taken through one of the cylinders, the portions being shown in elevation; Fig. 3, a horizontal sectional view on the line Z) Z) of Fig. 1. Figs. 4tot7, inclusive, are diagrammatic views showing the operation of the pistons; Fig. 8, a horizontal sectional view taken on the line 0 c of Fig. 1; Figs. 9 to 10, sectional views of a simple form of reversing-valve.
Similar reference-numerals in the several figures indicate similar parts.
The main frame of the motor consists of a single casting or structure embodying two similar cylinders or cylindrical chambers 1 and 2, open at the ends and adapted to be closed by top and bottom plates 3 and 4, secured steam-tight by suitable packing and bolts 5, as usual. At the sides and between the cylinders are chambers or passages 6 and 7, extending lengthwise of the frame and covered at the ends by the plates 3 and 4. The cylinders 1 and 2 are provided near their upper ends with ports 8 and 9 and at their lower ends with ports 10 and 11, all connecting with the passage 6, and near the center of the cylinders are ports 12 and 13, connecting with the chamber or passage 7. Also formed in the sides of the main frame are passages terminating in ports 14, 15, 16, and 17 in the cylinders 1 and 2, said passages connecting with passages formed in the end plates 3 and 4, so as to connect the port 14 with the upper end of cylinder 2, the port 15 with the lower end of cylinder 1, the port 16 with the lower end of cylinder 2, and the port 17 with the upper end of cylinder 1, as shown in the diagrammatic views.
19 and 20 indicate two similar and interchangeable pistons operatingin the cylinders 1 and 2, respectively, the former provided with three piston heads or rings 21, 22, and 23 and the latter with the similar heads or rings 24, 25, and 26. The pistons are connected to or formed with piston-rods 27, operating through suitable stuffing-boxes in the upper end plate 3 and pivoted to pitmen 28, connected tocranks 29 on a shaft 30, journaled in standards 31, formed upon or secured to the end or cover plate 3. The piston-rods are connected to or provided with cross-heads operating in suitable ways in the standards in the usual or any preferred manner.
The chambers or passages 6 and 7 are connected to steam- pipes 32 and 33, respectively, which extend to a reversing-valve casing 34, having ports 35 and 36, with which the pipes 32 and 33 connect, respectively, and an inletport 37, connected by a pipe 38 with a steamsupply and an exhaust-port 39. Within the valve-casing is a valve 40, having an operating-handle 41, a port 42, and a passage 43, these ports being so arranged relative to the ports that steam may be admitted to either of the passages 6 or 7 and the other passage connected to the exhaust-port, as will be understood, thus causing the reverse movements of the engine, as will be understood. Any other form of reversing-valve can be employed, if desired, the construction of the engine being such that asingle valve, as shown, is all that is required to regulate speed or accomplish the reversal of movement of the engine. l
The cranks to which the pistons are connected are arranged on the shaft-quartering, as shown, so that there will be no dead-centers to the engine and each of the pistons serve as valve devices for regulating the inletand exhaust of fluid to and from the other. As, for instance, in the position shown in Fig. 4, the fluid-supply being connected to the chamber 7 and chamber 6 with the exhaust, the steam or other fluid passes from port 13 between piston- heads 24 and 25 and port 15 to the lower end of cylinder 1, the air or the steam in the upper end of cylinder 1 being exhausted through port 17 between heads 25 and 26 to port 11 and passage 6. hen the ports are in the position shown in Fig. 5, steam is admitted through ports 12 and 16 to the lower end of cylinder 2 and is exhausted from the upper end of said cylinder through ports 14 and 8. In the position shown in Fig. 6 both pistons are descending, the steam from port 13 passing through port 17 to the upper end of cylinder 1 and the steam in the lower end of said cylinder exhausting through ports 15 and 9, and when the ports are as shown in Fig. 7 the piston 19 is in its lowest position and about torise, with piston 20 at half-stroke and descending, steam being admitted to the upper end through ports 12 and 1%. The various movements of the pistons will be readily understood from Figs. 4 to 7, which show the positions at the four quarters of the cycle of movement.
It will be understood that the motor can be reversed and governed entirely by a single reversing-valve such as I have shown. Inasmuch as the direction of movement depends upon the connection of the steam-supply with the passage 6 or 7, when steam is admitted to the latter, the ports 12 and 13 operate as the inlet-ports and when it is admitted to chamber 6 the ports 8 to 11 operate as inletports; but it is of course immaterial, as far as the operation of the motor is concerned, to which passage steam is supplied.
The parts of the motorare exceedingly few and of simple construction, and the cylinders being duplicates and the pistons interchangeable broken or worn parts may be replaced or repaired by unskilled operators at a nominal cost. Any suitable form of packing for the pistons may be employed and the other details of construction may be altered without departing from the spirit of myinvention.
By connecting the pistons'to the driven shaft by the quartering-cranks shown they not only each serve to transmit equal force to said shaft, but positively operate as valves for each other in whatever direction the motor may operate, and by simplifying the construction and dispensing with separate valves, valve-motions, and reversing-gear and other complicated parts I render the motor especially adapted for operating automobiles, launches, or other self-propelled vehicles for the operation of which it is not desirable to employ a mechanic or engineer.
