MECHANISM FOR EXERTING PRESSURE.
SPECIFICATION forming part of Letters Patent No. 718,621, dated. January 20, 1903.
Application filed February 24. 1902. Serial No. 95,204. (No model.)
To all whom it may concern:
Be it known that I, EDUARD GUENTHER, a citizen of the United States, and a resident of WVest New York, county of Hudson, and State of New Jersey, have invented a new and Improved Mechanism for Exerting Pressure, of which the following is a full, clear, and exact description. v
My invention relates to mechanism for exerting pressure, and is applicable to devices varying considerably in function, its purpose being to provide a very simple and powerful mechanism for exerting pressure upon gaseous, liquid, or even solid bodies. The pressure may be applied either for the purpose of propelling said bodies or, making use of the reaction principle, for propelling the structure, such as a ship or air-ship, which carries said mechanism, as well as for many other purposes, some of which will be indicated hereinafter.
To facilitate a clear understanding of my invention, I have hereunto appended two sheets of drawings, in which Figure 1 is a longitudinal sectional elevation on line 1 1 of Fig. 2, showing one form of mechanism for carrying out my invention. Fig. 2 is a cross-section thereof on line 2 2 of Fig. 1. Figs. 3 to 6 are diagrammatic longitudinal sectional elevations illustrating the I operation of the device shown in Figs. 1 and 2. Figs. 7 to 10 are similar views of another form of my invention. Fig. 11 is a cross-sectional elevation of the mechanism shown in Figs. 7 to 10. Fig. 12 is a longitudinal sectional elevation showing the application of my invention to the propulsion of a marine vessel.
I desire it to be clearly understood that while I have shown specific mechanism for effecting the result in viewit is my intention to protect the features of my invention as broadly as the state of the art will permit, and the novelty of my improved apparatus will be carefully defined in the appended claims.
As shown in Figs. 1 and 2, the invention comprises as its principal elements three partsviz., a conduit for the medium (fluid or solid) on which pressure is to be exerted, a pressure-exerting member arranged in said conduit, and mechanism for imparting a poculiar oscillating motion to this member, as will be set forth presently.
The conduit or casing in the particular instance shown consists of a tubular body A of rectangular cross-section and open at both ends, one of which may serve as the inlet and the other as the outlet. This body is represented as provided with a downward extension comprising parallel longitudinal walls A A between which may be located a fillingpiece A spaced from the wall or plate A so as to leave a slot or narrow chamber A between them. As shown in Fig. 1, this chamher is open toward the tube or conduit A, but is otherwise closed. The conduit has a top A and a bottom A extending to the wall A the chamber A being located centrally with respect to the side Walls of the tube or conduit A.
Within the conduit extends longitudinally a pressure-exerting member in the nature of a plate B, the ends of this member or' plate being free, and this plate is arranged to move in such a manner as to form a gradually-contractin g pocket, first with the top A and then with the bottom A or vice versa. In this movement the plate preferably always remains at a right angle to the central longitudinal plane of the conduit A. The movement may be described as an oscillation about a shifting center, and as aninstance of the many devices which mechanical skill and ingenuity may contrive for this purpose I have shown a Web B, extending centrally from the plate B into the chamber A where said web is pivotally connected, as at 0 with a crank-disk O or equivalent part on a shaft 0, to which motion may be imparted by a pulley C Vertically above the shaft 0 a stationary guide-pin A is projected across the chamber A and this pin engages the web B at the edges of a slot B the pin 0 being in the continuation of the slots axis.
The operation is as follows: Starting from the initial position shown in Figs. 1, 2, and 3, if the shaft is rotated in the direction indicated by the arrow in Fig. 1 the plate 13 will first be rocked on the pin A so as to bring the right-hand end of the plate down into the position shown in Fig. 4, while the left-hand end of the plate remains practically stationary in its upper position. This will obviously cause a pressure on the lower face of the plate, causing the fluid or other medium to be forced toward the left, and above the plate a suction will be produced to draw in a fresh supply of the medium and impart to it an impulse in the same direction. The position shown in Fig. 4 is obtained approximately after a quarter-revolution of the shaft O. As the pin C nears its lowest position the right-hand end of the plate B remains stationary and its left-hand end swings down, so as to finally lie close to the bottom A as indicated in Fig. 5. In passing from the position shown in Fig. 4 to that illustrated by Fig. 5 the flaring pocket formed between the plate B and the bottom A is contracted gradually, thus forcibly expelling the fluid from said pocket toward the left. At the same time the suction between the upper face of the plate B and the top A of the conduit A continues. During the further rotation of the shaft C the right-hand end of the plate B rises to the position shown in Fig. 6, and finally the plate returns to the original position shown in Fig. 1, forming first a flaring pocket with the top A and then gradually contracting said pocket to continue the n10- tion of the fluid in the same direction as before. If the shaft C is rotated in the opposite direction, the order of positions is simply reversedthat is, the plate B will pass successively through the positions shown in Figs. 1, 6, 5, 4, and 3, and of course the fluid or other medium will be propelled in the opposite direction through the conduit A.
The employment of the apparatus above described as a pump will be obvious. The attachment of suitable suction and delivery pipes to the ends of the conduit A is merely a matter of mechanical skill. This pump is reversible by simply reversing the shaft 0. The apparatus when working in air may be used as an air-pump or as a ventilator or blower for the va1'iotis, purposes for which such devices are used. If the conduit A is attached to the hull of a ship or toa suitable part of an air-ship, the mechanism will form an efficient propeller if placed in the longitudinal axis of the vessel or parallel thereto, while when disposed at an angle to such axis the mechanism will constitute a powerful steering device. My invention is applicable to the propulsion or compression or exhaustion of fluids, gaseous and liquid, and may also be made to operate on solid or semisolid material, such as powdered substances and heavy sticky juices or the like. Further, the mechanism may be used as a washing-machine, as it will exert an intermittent pressure on the clothes at difierent points and will automatically feed the clothes through the channel or conduit A. The mechanism may also be employed as a machine for kneading dough.
Another form of my invention is shown in Figs. 7 to 11. Here I arrange two superposed plates B B in the conduitA between the top A and the bottom A thereof and provide duplicate mechanism for imparting to the said pressure-exerting members the motion illustrated by Figs. 7 to 10. The webs B may in this case be arranged at the sides instead of centrally and worked by oppositely-projected cranks C on the shaft C; but the throw of each crank is only about one-half the height of the conduit A. From the position shown in Fig. 7 the right-hand ends of the two plates first swing together to form a tapering pocket, as in Fig. 8. Then the left-hand ends of the plates move toward each other to reach the position shown in Fig.9. Thereupon the righthand ends separate, as in Fig. 10, and finally the left-hand ends separate and return to the position shown in Fig. 7. This succession of movements obviously produces a suction at the right-hand end of the conduit and a delivery action at the left-hand end, as indicated by the arrows. If the shaft 0' is rotated in the opposite direction, the fluid will travel from left to right.
With a construction comprising two movable plates, as in Figs. 7 to 11, the conduit A, or at least the top A and bottom A thereof, may be omitted, although the action will be more powerful if a complete conduit is used. While it is true the two plates B B form a pocket with each other and may therefore exert a pressure and propelling action without the cooperation of the conduit-walls, two additional pockets are formed when the conduit-walls A A are provided and the efficiency is considerably increased.
In Fig. 12, A indicates a conduit extending lengthwise of a marine vessel below the waterline, said conduit being normally open at both ends, so that it is filled with water. In said conduit is arranged the transversely-movable pressure exerting or propelling plate B, which receives motion by means of pistons D D, working in cylindersE E, and connected with said plate by piston-rods F F. In order to properly govern the admission of the motive fluid to the driving-cylinders E E, so that the plate B will have the motion hereinbefore described with reference to Figs. 1 to 6, I provide valves G G, of which the valve G may be the inlet-valve for the cylinder E, while the valve G is the outlet-valve for the cylinder E. These two valves are worked by a lever H, fulcrumed at H and connected with the piston-rod F. Thus the piston-rod F controls the inlet-valve of one cylinder and the outlet-valve of the other cylinder. Similarly, the piston-rod F will through the medium of a lever 11 control the inlet-valve of the cylinder E and the outlet-valve of the cylinder E. These two valves are not shown in the drawings; but it will be understood that they correspond exactly in construction to the valves G G. In order to facilitate the making of repairs, I may provide gates I with suitable raising and lowering mechanism J, so that the part of the conduit A which contains the pressure-exerting plate B may be ICC separated from the outer portions of the conduit. Upon then removing a section of the conduit between the two gates I the plate B becomes readily accessible. Gates of this character may also be provided with the constructions shown in Figs. 1, 2, and 11.
In each of the constructions hereinbefore described the movement of the pressure-exerting plate forces the water or other medium against a relatively solid surface or resistance, which may be formed bythe stationary wall of a conduit, by the hull of a vessel, or by another pressure-exerting plate. I wish to state, however, that if a propelling or pressure-exerting plate is given a movement of the character described it will exert a propelling action even if there is no solid resistance cooperating with it, as the relatively stationary body of water or other fluid will form a sufficient resistance to obtain a useful result. It is preferable, however, that the device should consist of two cooperating members extending longitudinally of the direction in which pressure is to be exerted, the said members having free ends and being combined with mechanism for separating them first at one end and then at the other and then again bringing them together in the same succession. This relative movement may be effected by moving both members or only one of them. Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination of a pipe or conduit having an inlet and an outlet, a pressure-exerting member movable transversely in said conduit, a web extending from said member in a plane substantially parallel to the longitudinal central plane of the conduit, said web being provided with a transverse guideway, a stationary guide engaging said guideway and a rotary shaft having an eccentric pivotal connection with said Web, the point of pivotal connection being situated in the continuation of the guideway.
2. The combination of two plates movable toward each other into close proximity and also movable away from each other at both ends to form a pocket between them, and mechanism for causing said plates to first approach each other at one end and then at the other end, and thereupon to recede from each other first at that end at which they first approached each other, and then at the other end.
3'. The combination of a pipe or conduit having an inlet and an outlet, two pressureexerting plates extending lengthwise of the conduit in the same portion thereof, said plates being movable transversely toward and from each other, and also relatively to the walls of the conduit, and means for causing said plates to move together and then separate alternately at opposite ends.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
